Abstract:

Chemistry has been experiencing dramatic changes since the beginning of the twentieth century. The enterprise is diverse and complex, and it involves international collaboration. However, the trends in modern chemistry do not seem to be reflected in education, although many children show a strong interest in natural phenomena from an early age and demonstrate an outstanding ability to think creatively and in abstract terms. This presentation summarises the global trends in Nobel Laureates in Chemistry from 1901 to 2012 in order to illustrate how giftedness in chemistry is a requirement for the new century. This presentation proposes different chemistry education modes for gifted students in formal and informal settings. Some of Ehime University’s special gifted education programmes, which deal with identification, curriculum development, practice, and assessment, are introduced as case examples of chemistry education for the gifted. This presentation also analyses the effects of special education programmes and discusses the similarities and differences between their effects on gifted students and regular students. The development of chemistry curricula and teaching materials that accommodate the special needs of gifted students and the implementation of related teaching methods and assessments are relevant to all teaching subjects, school types, and education in general. Moreover, they can be used in the educational activities of communities and societies around the world.

Biography:

Karin Larsson is a Professor in Inorganic Chemistry at the Dept. of Chemistry-Ångström Laboratory, Uppsala University, Sweden, and Guest Professor at the University of Science and Technology Liaoning, China. In addition, Karin Larsson is elected member of IVA (Royal Swedish Academy of Engineering Sciences), division V (Mining and Materials;Vice-Chair). Prof. Karin Larsson is today the head of the Theoretical Materials Chemistry Group at the Div. of Inorganic Chemistry, Dept. of Chemistry-Ångström laboratory. The scientific focus is on interpretation, understanding and prediction of the following processes/properties for both solid/gas interfaces, as well as for solid/liquid interfaces; i) CVD growth (e.g. diamond, BN, and graphene), iii) interfacial processes for renewable energy applications (e.g. electrochemical processes), and iv) bio-functionalization of surfaces (e.g. bone regeneration). 

Abstract:

Diamond is a widely known material for its many excellent properties (eg., high thermal conductivity, high breakdown voltage, transparency, chemical inertness and bio-compatibility). A B-doped diamond is an excellent p-type material for solar cell usage. Due to some specific properties (e.g., large chemical inertness, very high carrier mobility for both electron and holes, high transparency), it is considered as one of the strongest candidates for photovoltaic electric generation. However, in order to implement the usage of diamond in solar energy applications, properties like the i) electrochemical window, ii) possibility for interfacial charge transfer, and iii) stability of functionalized surface, have to be further studied and optimized.

In the past investigation, the adsorption of different dye molecules onto H-terminated diamond (111) surfaces, have been theoretically studied using Density Functional Theory (DFT) calculations under periodic boundary conditions. The diamond surfaces were B-doped in order to make them p-type semi-conducting. The choice of dyes was based on the match between the electronic structures of these H-terminated B-doped diamond surfaces, and the respective dye molecules. The dye molecules in the present study include C26H13NO3S4 (A), C35H37NO2S3 (B), C34H38OS2 (C), C32H36OS2 (D), and C31H35S3Br (E). These dyes differ in the various functional groups, which have the role as electron acceptors. The main goal with the present study was thereby to investigate and compare the photovoltaic efficiency of the various dyes when attached to B-doped and H-terminated diamond (111) surfaces. Of a special interest was to study the i) absorption spectra of the dye, ii) degree of electron transfer over the diamond//dye interface, iii) electron transfer arte, iv) electron-hole recombination, and v) diamond//dye bond strength.

The calculated absorption spectra for in principle all of the different dyes were shown to be located in the most intense part of the sunlight spectrum. For the E dye, the spectrums were more positioned towards the UV light range. The usage of a combination of these different dyes would hence be an optimal choice in order to improve the light harvesting in a photovoltaic process.

Furthermore, the calculations identified the LUMO’s for the B, C and D dyes to be positioned on the upper end of the molecules, which also will be the position of the electron acceptor when being excited by light. For dyes A and E, there were though certain extensions of the LUMO’s to the lower end of the molecules (i.e., towards the diamond surface), which will also increase the electron-hole recombination rates.

Calculation of electron transfer was to ensure that the HOMO of these dyes were positioned at a lower energy compared to the upper edge of the valence band of the B-doped diamond surface. Moreover, all dyes were found to bind with strong C-C covalent bonds to the diamond (111) surface.

Biography:

Kimberly B. Fields has completed her PhD at the age of 35 years from University of South Florida. She is an instructor in chemistry with eight years of experience in higher education. She has published 7 papers in peer-reviewed journals and has written two book chapters. Current research interests are in chemical education with an emphasis on organic chemistry and a key member of the USF Science in Florence program development team.   
 

Abstract:

The University of South Florida (USF), with an undergraduate enrollment of 31,000 students, has a vibrant study abroad program involving hundreds of students, dozens of faculty, and over 60 countries. We have developed and administer a STEM study abroad program called USF Science in Florence which is centered in Florence, Italy. Traditionally, study abroad programs do not include chemistry, physics, or physician observation/comparative health care systems courses – that are completely in line with the students’ STEM major. In our study abroad program, Organic Chemistry I & II, Physics I with Calculus, and General Biochemistry are taught with the same rigor as when those courses are taught during the standard semester. This affords STEM majors the ability to stay on track for their respective degrees while experiencing study abroad. The study abroad experience is viewed positively by prospective employers and post-graduate program selection committees. Our STEM study abroad program is called Science in Florence and is centered in Florence, Italy.

The class sizes are small (30 students or less) with many more opportunities for individualized instruction and support than the typical USF on-campus experience. The courses offered in Florence, usually are high-enrollment courses (200-300 students per lecture) when taught in Tampa, FL. Field learning excursions to reinforce course learning objectives are incorporated as much as possible. Tours to local establishments take place weekly and include Officina Profumo – Farmaceutica di Santa Maria Novella, the Museo Galileo, and Fattoria di Maiano. Discussion of relevant scientific topics dovetail nicely with topics in chemistry. Feedback from students involved are overwhelmingly positive of the program

Biography:

Andreas Schedy studied from 2011 to 2016 at the University of Education Freiburg for teaching at secondary schools in the subjects of chemistry, mathematics and geography and graduated in 2016 with the first state examination. Since July 2016 he has been doing his doctorate in the working group of Prof. Dr. Marco Oetken at the University of Education Freiburg, funded by a doctoral scholarship. As part of his doctoral thesis, Mr. Schedy deals with the experimental development of the topic Graphene. 

Abstract:

The two-dimensional modification of carbon which is also known as “graphene” is an extremely interesting material due to its physical properties, such as a very high electrical conductivity and an intrinsic mechanical strength that is even better than that of steel. For that reason, it has already been called the “miracle material“ of the 21st century. Up to now, the synthesis of graphene was to dangerous to implement it into the school curricula. The authors present a method of synthesizing graphene which can be put into practice at school without hesitation. In addition, the authors present some experiments with which  the varying properties of graphene oxide and graphene during synthesis can be shown. In this way, different structure property relationships, which appear to be one of the most important concepts in chemistry lessons, can be analyzed. The authors also present a field of application for graphene

Mª Gloria Quintanilla López became Titular Professor in Organic Chemistry at the University of Alcalá in 1985. Her teaching task is focussed mainly to the students of Health Biology, Chemistry and Pharmacy. As researcher she has dealt with Organic Synthesis and Electrochemistry. She is Erasmus Coordinator for the Chemistry Faculty since 1989 and organized the Choir of the University for the last 39 years. In the last ten years she is the coordinator of a teaching innovation group of the University of Alcalá based in the “Reflection activity”.

Abstract:

All social networking such as Facebook, Twitter or WhatsApp produce an immediacy which prevents, especially the young people, from going deeper in any thought or communication among others. As a contrast, a group of teachers of different subjects of the University of Alcalá, headed and caught up by an Organic Chemistry professor, have implemented a teaching strategy in which the main objective is the reflection, named “Weekly Reflection Papers”, (WRP). Initially in this experience, the students handed in to the lecturer every week their “weekly assignments”, in which they schematically express the most important ideas related to the topic presented during the classes of the previous week including also their impressions or comments on those aspects which they found especially difficult or interesting.  Teachers give back to the students the corrected WRP and respond to the student’s comments. The implemented strategy represents an excellent vehicle to allow us to explore and analyse the learning process.

However, we checked that the reflective ability of students had to be enhanced, consequently in this communication we describe how along the years we have put more emphasis in the way the reflection has to be done helped by questions as: “What is the most important contribution given to you by the professor in order to increase your personal development? What changes have been produced in your intellectual baggage as a consequence of the classes? Which are the most difficult aspects you have found in your learning process? What can you suggest to improve the teaching and learning process? Where can you find in your real life the knowledges you have recently acquired?”

Mian Jiang completed his PhD from Wuhan University and research associate studies from Northwestern University and New Mexico State University respectively. He currently teaches analytical chemistry at the University of Houston Downtown. He has published more than 50 papers in peer-reviewed journals, and served in various professional capacities in his institution and fields.

Abstract:

             Petrochemical components were recently incorporated into our curricular efforts. The main driving force lies at the societal relevance of a sustainable analytical chemistry curriculum. Crude oil exploration, processing, and production of basic, intermediate, and final petrochemicals, all bear the natures of material and characterization studies. They are in line with the University’s high-impact education mission and one of the local economic focuses (as the world’s energy capital). Despite of the natural match or extension between analytical sciences and petro-industry, few reports in this curricular incorporation were published thus far. We started with the incorporation of petrochemical experiments into undergraduate research and STEM workshops. These directly address a wide spectrum of petroleum/petrochemical industry and study. The experiments, designed and tailored to reflect material science and characterization means, included the crude oil viscosity measurement (addressing the up-stream exploration sector), corrosion quantitation (for the mid-stream pipeline or transportation), and preliminary polymer production and characterization (for down-stream end-user products). These ideas were also tested in the existing analytical chemistry classes for teaching effectiveness. Initial responses were positive, with the rising enrollments and motivation to learn. Some students showed interests to deepen these practice into Problem-based learning (PBL) after regular labs. Our current activities concentrate on the embedding of non-aqueous (petroleum liquid) titration for chemical analysis, and characterization of hydrocarbon-bearing rocks and carcinogen petrochemicals (benzene, toluene, ethylbenzene, and xylene, BTEX) in instrumental analysis. Our efforts in updating analytical curriculum are preliminary and forward-looking. They have the potential to improve learning in both material and characterization studies, and may expand into other chemistry disciplines or interdisciplinary fields.

Arnos Arshaki Hovhannisyan received his doctorate at the age of 31 from the Moscow Technical  Institute of Fine Chemical Technologie. He is Doctor of Chemical Sciences, Professor. He is head of Laboratory of Polymer Dispersions.  He published more than 100 works in well-known journals and a monograph titled "The Theory of Emulsion Polymerization".

Abstract:

Polymerization in monomer - water heterogeneous systems has special properties different from those of other methods of radical polymerization. These properties are detected when the polymerization is conducted in highly disperse systems, or what is common to be considered as emulsion polymerization (EP).

The main components of emulsion polymerization are the monomer, water, emulsifier and initiator. Usually emulsifier molecules don’t participate in the elementary acts of polymerization; however, the rate and degree of EP are increased simultaneously when the concentration of the emulsifier is increased.

There are many theories and models that describe the mechanism of emulsion polymerization. In some of these, the authors introduce the emulsifier concentration in the kinetic equations of radical polymerization. These models and theories are briefly discussed in this presentation.

The main purpose of this report is to represent the results of several experimental studies that show a possible link between the specifics of EP and physical and chemical processes occurring at monomer-water interfaces. In these experiments the polymerization is carried out without the use of emulsifier under static conditions in styrene-water, vinyl acetate-water and chloroprene-water systems, from which is clearly visible the topological picture of dispersed particles generation in a narrow interface of the monomer – water system.

Lucila Giammatteo studied pharmaceutical and biological chemistry at Universidad Nacional Autónoma de México. She has been working as a chemistry teacher specialized in multicultural education at Instituto Tecnológico de Estudios Superiores de Monterrey for the past 4 years. She is currently studying a Master's degree in Chemistry Teaching at Universidad Nacional Autónoma de México.

Abstract:

Given the changes with the last educational reform in Mexico, most high-schools have changed to a competency-based model. Since there is a huge gap between the instruction and the evaluation process, there is an evident need to homologate both.  This paper proposes a novel strategy to evaluate the competencies which are related to laboratory practices, such as formulating hypothesis, systematizing information, applying security norms, handling residues, collecting data, contrasting results in an experiment and communicating conclusions.

Experimental sciences specific competencies were selected and evaluated with the use of an assessment tool where the students' levels of achievements were described considering the curriculum and the graduate's profile. A random sample of students averaged 16 years old was chosen. After submitting the laboratory report, Students' feedback was delivered through Blackboard platform in prompt time, so the students could take those comments into consideration and improve their performance in the following practices. A total of 7 practices were evaluated in this manner during a semester in an inorganic chemistry high-school course. The topics were chosen in such a way that those seen in theoretical classes were reinforced with the laboratory practices.

Abstract:

In a number of research studies, we have dealt with a number of attributes which are of paramount importance to improve the quality of life for any well-organized society.  The main target in this set of studies is to both focus and underline the importance of the knowledge in the state of the art.  It is crucial to realize that nowadays broad topics such as Robotic, Artificial Intelligence, Data mining, Nano science, Nanotechnology and Biotechnology are the basis for any development to be achieve in the short, medium and long term.  We do recognize the importance of these broad and essential areas of knowledge and development but it must be admitted that as a country, we have not done the work properly and in due time. The offset with reference to developed countries is most significant.  It is rather straightforward to conclude that our efforts in these areas are not enough to overcome these difficulties. Chile is sad example of a country, where highly qualify professionals are, in number, either scarce or non-existing.  We believe that we must develop and increase economical resources on a regular basis, so as attributes such proactivity, novel ideas, entrepreneurship and social business among others are indeed to be considered seriously.  Chile has considerable resources, such as Cupper, Lithium and Rare Earths and a dessert with clean skies and sun light (so this is without any doubt a rather unlimited supply of solar energy).  Only scarce efforts have been dedicated to obtain benefit of these free sources.  There are also, a number of other traditional resources such as a significant and large forest, wine and other commodities.  A better analysis of both our strength and weak points should be taken into account and people should be seduced to work for the country welfare.  It is obvious the role to be played by a high level training in subjects such as Chemistry and Biology in addition to Mathematics, Physics, Computing, will be essential to have available a reasonable number of competent professional working for the productive sector.

Kiramat Shah is Assistant Professor at Institute of Chemical Sciences, University of Swat, Swat KPK Pakistan. He has obtained his Ph.D degree from International Center for Chemical and Biological Sciences University of Karachi, Karachi Pakistan. He is synthesizing macrocycles and macromolecules using different advanced reactions particularly Azide -Alkyne Click reaction, Glaser coupling, Sonogashira coupling, amide bond formation using coupling reagents and Mannich reaction. For the characterization of these molecules we use different techniques like 1H NMR, 13C NMR, advanced 2D NMR, EI-MS, ESI-MS, MALDI, UV-vis and FT-IR spectroscopy. To explore the chemo-sensing properties of these macrocycles and macromolecules for different antibiotics, dyes, explosives and metal ions we use UV-visible and Fluorescence spectroscopy.

Abstract:

The monitoring of pharmaceutical drugs in the environment is of great importance word wide. For example, in Karachi Pakistan due to contaminated water six children were died and about 200 were fill ill in 2005. A large number of pharmaceutical drugs in highly alarming amount were found in different components of drinking water (surface water, drainage, and effluent) of Karachi in the microgram-per-liter range during bioassay directed chemical analysis. The photophysical evaluation of supramolecular organic molecules as optical probes for detection of water toxins has been recognized to be very selective, sensitive, and economical as compared to the previously used methodologies.

Synthesis, characterization and molecular recognition properties of fluorene based supramolecular cleft is reported. The cleft molecule was prepared in a single-step with good yield (85% yield), by linking Fluorene with 1-ethyl piperazine. The cleft molecule was carefully characterized using various spectroscopic techniques such as NMR and mass spectrometry. The supramolecular interaction of cleft with amoxicillin, 6APA, aspirin, captopril, cefotaxime, ceftriaxone, cefuroxime, diclofenac, penicillin, and cephradine was evaluated by fluorescent spectroscopy. The molecular recognition studies showed that amoxicillin selectively binds with cleft in the presence of other drugs. The analytical method developed for the supramolecular interaction of molecular cleft and amoxicillin was validated at varying pH, concentration and temperature during recognition process. Job's plots indicated that the stochiometry of the interactions between the cleft and the amoxicillin was 1:1.

Abstract:

Salah Akkal think that it is necessary to link the theoretical side with the practical aspect of chemistry teaching in a way that allows the student to get closer to this understanding, since chemistry touches large areas in our daily life. We do not forget that for students of fine science and technology, their choice of chemistry, Or graduate studies in chemistry after the end of the common trunk, they must have a solid composition in the application of chemistry supports their theoretical balance and allows them to enter the world of chemical industry, pharmaceuticals and petrochemicals.

The student's study of the chemistry experiments also gives rise to the enthusiasm for following up on the observations and conclusions of the experiments of chemistry

One of the current priorities is to give importance to the practical aspect by providing specialized laboratories for this purpose for the first years of university so as to ensure an integrated composition, although this is not easy because of the large number of students in the common trunk, but follow-up and supervision can overcome the various difficulties by forming committees A follow-up aimed at coordinating and creating the appropriate framework to put this reform on the right track and from which to reap the desired results.

Henadzi Filipenka graduated from the Leningrad Electro technical Institute. He grew monocrystals of iron-yttrium garnet. Worked out technologies of powder metallurgy in the Grodno branch of the Kazan Research Radio Technology Institute. He worked as a teacher of materials science in Grodno Electro technical College.

Abstract:

The main problem is that using X-rays, we have determined the crystal lattices of different materials, and why they are so, and not others are not yet known. For example, copper crystallizes in the fcc lattice, and iron in the bcc, which becomes fcc on heating, this is used for heat treatment of steels. Copper does not change the crystal lattice when heated. There are many factors affecting the crystallization in the literature, so they decided to remove them as much as possible, and the metal model in the article, say so, is ideal, i.e. all atoms are the same (pure metal) without inclusions, without implants, without defects, etc. using the Hall effect and other data on properties, as well as the calculations of Ashcroft and Mermin, my main determining factor for the type of lattice was the core of the atom or ion, which resulted from the transfer of some electrons to the conduction band. It turned out that the metal bond is due not only to the socialization of electrons, but also to external electrons of atomic cores, which determine the direction or type of the crystal lattice. The change in the type of metal lattice can be connected with the transition of an electron to the conduction band or its return from this zone. Phase transition. It is shown that in the general case, the metal bond in the closest packages (hec and fcc) between the centrally chosen atom and its neighbours is presumably carried out by means of nine (9) directional bonds, in contrast to the number of neighbours equal to 12 (twelve) (coordination number). Probably the "alien" 3 (three) atoms are present in the coordination number 12 stereometrically, and not because of the connection. The answer is to give an experimental test.

Qualified in education as well as research, she uses teaching strategies such as Process Orientated Guided Inquiry Learning (POGIL) and she supports that through action research to maximize the benefit of such pedagogical approaches in Chemistry in the Foundation Program. Currently published 5 papers on this work.

Abstract:

In this paper, we report on outcomes from a recently ended chemistry education research project that facilitated the transition of a western pedagogical practice into a middle-eastern context like Qatar using a curriculum evaluation framework. An inquiry based approach such as Process Oriented Guided Inquiry Learning (POGIL) was implemented in the foundation chemistry course at Weill Cornell Medicine in Qatar for students to develop key process skills such as teamwork, collaboration, and critical thinking, which foster lifelong learning and professional growth in medicine. Student-centered learning introduced at the foundational level can maximize their development, especially in the sciences.

The positive impact of POGIL was evident from students’ improvement of their cognitive and affective characteristics in a trans-national setting thus demonstrating efficacy and cultural transferability of the pedagogy. The study also focuses the effect of POGIL activities on students’ confidence level in understanding of essential key concepts in chemistry. The talk also reflects the chemistry educator’s scholarship of teaching and learning activities related to discipline-based education research that used inquiry-based approaches in Qatar over a 6 year period, 3 of which we funded by the Qatar Foundation.

Abstract:

 Coals are heterogeneous, complex and noncrystalline macromolecules containing both organic and inorganic materials. Inorganic constituents, especially sulfur plays a decisive role in the utilization of coal systems. The undesirable ash and sulfur contents can be reduced using physical–chemical and chemical methods. ‘Froth flotation’ is a physical–chemical method that is capable of reducing pyritic sulfur and the ash content of coal. In this research work, key operating variable (pH, air flow rate, composition of feed and separation time) were investigated in a lab-scale froth flotation unit and separation time & air flow rate were found to be the most effective variables for the removal of pyrite sulfur and ash contents from the coal samples. Wetting agent (Polyvinyl Alcohol) and frothing agent (Pine oil) are used that helps for stabilizing air bubble in the froth flotation column and capturing the pyrite sulfur from the column. Present research showed that PVA has a good role as good wetting agent for the pyrite sulfur/coal mixture. Considering the market price of PVA, it is the most feasible option as wetting agent. The optimum values for pH, separation time and air velocity were 7, 40 minutes and 90 scfh respectively. At these optimum values removal of sulfur and ash contents were highest. This combined approach consisting of physical followed by chemical cleaning of coal was found to have potential applications for significant removal of ash and sulfur from bituminous coal with less investment and less generation of waste water.

Abstract:

One of the major classes of substances common to living systems are carbohydrate so these compounds as very familiar to us that we call many of them as sugar [1,2]. Recently, we have reported the new monosaccharide’s barcoding that caused drawing of Fischer projection of the linear monosaccharaides to be easily [3] and this new barcodes forced the invention of the new monosaccharide’s osazone chart [4]. In this educational research a new epimeric chart (Scheme 1, left) introduced for easily determination of the kind of epimers in each monosaccharide using the corresponding barcode. This new epimeric chart is facilitating the determination and the prediction of any kind of epimers in each monosaccharide. Osazone chart (Scheme 1, right) indicated the new determination rule for finding of a pair aldose and a ketose that make the same osazone.

Abstract:

The 21st century is the era of ‘a knowledge-based society’ where new knowledge, information and technology are becoming increasingly important for activities in all walks of life, and science is the driving force. The purpose of this study was to examine the contemporary science lessons in primary science classrooms. A pilot study was conducted in a grade 5 regular science classroom related to the process of ‘dissolving’. The pilot lesson had three stages: 1) sharing scientific language, 2) practicing scientific methods and experimental skills, and 3) innovative application. This lesson model was based on an idea of science education as a second language education. The children did not consider the introduction part of sharing scientific language to be difficult and their self-evaluation of keenness to learn was high. In the second part which involved practicing scientific methods and experimental skills, the difficulty level of the lesson showed an increase in their self-evaluation. It seemed that self-confidence also increased slightly at this stage. In the final stage involving innovative application, the children designed their original experiments, and discussed what was new in their findings. In the final stage, the self-evaluation of difficulty of the lesson further increased while their self-confidence and self-evaluation of keenness to learn rose as well. In conclusion, primary students can consistently and intentionally manipulate ‘scientific language and metaphor’, confidently face difficult questions and discuss something new about their findings collaboratively.

Abstract:

Current chemistry is developing rapidly and strongly affects human everyday lives. For this reason, chemistry is considered to be an important part of education for the current and future population. There is also expert consensus that science education (including chemistry) should be a compulsory part of the education of all children. But according to research findings (for example PISA) chemistry belongs to the least favourite school subjects. Because the socio-economic success of Europe 2020 depends on education of new generation, new ways of chemistry teaching/ learning which should prepare today’s children for adult roles as citizens, employees, managers, entrepreneurs, and parents, are sought. So a very important question arises how to motivate students to learn chemistry. In the presentation the most important factors influencing student interest in chemistry and ways how to support student engagement in learning of chemistry will be presented. Big attention will be paid to the innovative teaching methods of chemistry. Because the quality of teachers is one of the most important factors influencing the quality and effectiveness of chemistry education and student performance innovative ways of teacher education will be discussed.

Abstract:

Science education  including chemistry is undergoing changes due to its increasing importance these days, as it faces economic and social challenges. It is possible to register these changes in most European countries as well as the USA. Society requires to prepare the younger generation for the 21st century. We need a workforce with generally higher levels of STEM (Science, Technology, Engineering and Mathematics) literacy, as well as a sufficient number of highly gifted individuals entering scientific and engineering careers. To carry out these requirements it is necessary to change way of education and to find its appropriate content. Experts are trying to define a new paradigm of science education. But in order to be successful, important curricular changes have to be accepted by all of the stakeholders in education: students, their parents, politicians and especially by teachers, who should implement these curricular changes into practice. We will present research findings of the Czech Republic concerning the identification of views on science education, what opinions on current science education are held by stakeholders and what priority should be preferred in their opinion. The appropriate content of school chemistry will be discussed.

Abstract:

Generations of teachers and lecturers of chemistry have aimed at stimulating the curiosity of their students. Kindling an interest in chemistry for nonchemistry majors such as design students is even more of a challenge. Traditional photographic processes such as William Henry Fox Talbot’s calotype process are a link between the artistic and scientific disciplines. In 2−3 day workshops, design students without a major background in chemistry were able to define a reproducible protocol for Talbot’s gallic acid containing calotype process. The aim was to offer students the possibility to discover the chemical process on their own and to translate the procedure into creative artwork. With the experimental concept presented herein, students can be taught to approach an issue in a systematic way, to practice their problem solving skills, and to experience chemistry in a hands-on learning environment. Due to the workshop setup students can be coached individually in accordance with their progress. They can understand the chemical process, manipulate it, and use it in an artistic fashion. However, the molecular interpretation of a photograph is the means to an end. Photography is a well-known, ubiquitous process, and even today, young students are fascinated by the moment when the picture becomes visible in the dark room. Labor intensive photographs are appreciated in a different way than images taken with digital cameras or smartphones. Students without a chemical background succeeded in formulating a reproducible protocol for the calotype process and were able to pass on their knowledge to fellow students.

Abstract:

Fatty acid amides are an extensive family of cell signaling lipids with the general structure of R-CO-NH-Y.  This structural simplicity belies a wealth of diversity amongst this lipid family as the R-group is derived from fatty acids (R-COOH) and the Y-group is derived from a number of biogenic amines (H₂N-Y).  The fatty acid amide family is divided into different classes, which are defined by parent amines.  Examples include the N-acylethanolamines (NAEs, R-CO-NH-CH₂-CH₂OH), the N-acylglycines (NAGs, R-CO-NH-CH₂-COOH), and the fatty acid primary amides (PFAMs, R-CO-NH₂). In addition to the NAEs, the NAGs, and the PFAMs, other classes of fatty acid amides are known.  As the best known fatty acid amide is N-arachidonoylethanolamine (anandamide), a fatty acid amide found in the human brain that binds to the cannabinoid receptors.

The Merkler laboratory has had a long interest in the fatty acid amides, with a focus on their biosynthesis. We and others have demonstrated that the NAGs and the NAEs are precursors to the PFAMs and were the first to identify N-oleoylglycine from a mammalian source, long-chain N-acylserotonins from Drosophila, and have characterized a set of N-acyltransferases from mammals, Drosophila melanogaster, the silkworm (Bombyx mori), and the red flour beetle (Tribolium castaneum).  The fatty acid amide field is littered with many unanswered questions, including (a) have all the naturally-occurring fatty acid amides been uncovered, (b) which enzymes are involved in fatty acid amide metabolism in vivo, and (c) what are the respective contributions made by divergent pathways of fatty acid amide metabolism.

Abstract:

There is evidence in the literature that novice learners benefit from direct instructional methods while more experienced learners benefit from a more discovery-based approach. When a task efficient for novice learners becomes inefficient for experienced learners, it is called the expertise reversal effect, and illustrates the importance of being able to tailor a exercise to the level of the learner. This becomes especially relevant with the increasing use of web-based learning, where it is possible to tailor every small step of the learning process giving each individual a unique learning experience. To do this, we need a continuous monitoring of the level of knowledge of the learner. We designed a self-monitoring test to see if the students were able to evaluate their own level of knowledge, and a rapid science-based test in a specific area of science. We compared both tests with traditional measures of knowledge.
