On the nature of "context" in chemical education

Some of the most pressing problems currently facing chemical education throughout the world are rehearsed. It is suggested that if the notion of "context" is to be used as the basis for an address to these problems, it must enable a number of challenges to be met. Four generic models of "context" are identified that are currently used or that may be used in some form within chemical education as the basis for curriculum design. It is suggested that a model based on physical settings, together with their cultural justifications, and taught with a socio-cultural perspective on learning, is likely to meet those challenges most fully. A number of reasons why the relative efficacies of these four models of approaches cannot be evaluated from the existing research literature are suggested. Finally, an established model for the representation of the development of curricula is used to discuss the development and evaluation of context-based chemical curricula.

Using spreadsheets in chemical education to avoid symbolic mathematics.

Traditionally, quantum theory has traditionally relied heavily on the use of  mathematics. However, there is a significant cohort of students who are  weak in mathematics, for example, students who are majoring in   biochemistry, biological sciences, etc. This paper reports on the use of  spreadsheets to generate approximate numerical solutions and visual  (graphical) descriptions as a method of avoiding or minimizing symbolic  manipulations, mathematical derivations and numerical computation. A  specific example from quantum theory is provided. Some aspects of  educational pedagogy of spreadsheet usage are discussed.

Chemical education research

Every field of knowledge has two aspects: a practice component, and research into the advancement of the discipline. Chemical education is the same. Chemical education research (CER) aims to evaluate improvements and innovation in practice and also investigate how students learn chemistry. Examples illustrate the scope of CER, with analogies to better well-known examples of research in chemistry.

One recurring theme in chemical education is the improvement of existing laboratory exercises, the development of new laboratory exercises, and the testing of the activities to ensure their scientific validity and robustness, and finally evaluation and feedback to assess the effectiveness of the experiment by students and teaching staff.

Another active area of research is the analysis of curriculum in terms of logical versus psychological progressions of topics order, and trials on better sequences of topics for better outcomes.

have lead to advances in chemistry, with microwave-assisted synthesis, microfluidic devices, and better spectrometers to name just a few. So too, advances in technology have changed the practice of chemical education.

Other CER has examined new uses for mobile phones, using podcasts to enhance lectures, as flashcards, or to access chemistry resources, student-created videos and photo blogs, and other advances in technology.

Yet another area of CER is in the development and validation of these survey instruments.

Research is about collecting proof to support or refute a hypothesis. Chemical education research is no different. Chemical education seeks to improve the learning of chemical science. Chemical education research collects data to evaluate whether a particular course of action is good or bad for learning.

Chemistry and Chemical Education Through Text and Image: Analysis of Twentieth Century Textbooks Used in Brazilian Context

Assuming that textbooks give literary expression to cultural and ideological values of a nation or group, we propose the analysis of chemistry textbooks used in Brazilian universities throughout the twentieth century. We analyzed iconographic and textual aspects of 31 textbooks which had significant diffusion in the context of Brazilian universities at that period. As a result of the iconographic analysis, nine categories of images were proposed: (1) laboratory and experimentation, (2) industry and production, (3) graphs and diagrams, (4) illustrations related to daily life, (5) models, (6) illustrations related to the history of science, (7) pictures or diagrams of animal, vegetable or mineral samples, (8) analogies and (9) concepts of physics. The distribution of images among the categories showed a different emphasis in the presentation of chemical content due to a commitment to different conceptions of chemistry over the period. So, we started with chemistry as an experimental science in the early twentieth century, with an emphasis change to the principles of chemistry from the 1950s, culminating in a chemistry of undeniable technological influence. Results showed that reflections not only on the history of science, but on the history of science education, may be useful for the improvement of science education.

ConfChem Conference on A Virtual Colloquium to Sustain and Celebrate IYC 2011 Initiatives in Global Chemical Education—The Global Experiment of the IYC2011: Creating Online Communities for Education and Science

The Global Experiment, Water: A Chemical Solution, was one of the flagship activities of the International Year of Chemistry (IYC). During the virtual colloquium of the spring 2012 online ConfChem conference, the main results of this year-long experiment were presented and discussed online for a week. Some of the main conclusions of the virtual conversations relate to the benefits of creating online communities of people sharing similar interests, the use of online educational platforms to gather massive amounts of data, and specific questions about the development of this IYC initiative. The activities of the global water experiment (GWE) were designed by a team of experts and the protocols are available online on the GWE Web site. The results were shown in one interactive world map that allowed students to learn about data visualization, validation, and interpretation. The feedback obtained from the participants of the GWE and later by the contributors of the virtual colloquium was very positive. Many participants asked specific and technical questions about the development of this experiment, while others excitedly endorsed the convenience of these large open-access activities to promote chemistry worldwide. The estimate is that over 2 million people took part in the GWE during the IYC. This communication summarizes one of the invited papers to the ConfChem online conference: A Virtual Colloquium to Sustain and Celebrate IYC 2011 Initiatives in Global Chemical Education, held from May 18 to June 29, 2012 and hosted by the ACS DivCHED Committee on Computers in Chemical Education and the IUPAC Committee on Chemistry Education.

Use of spreadsheet simulations in university chemistry education

Students who are strong in logical-mathematical intelligence have a natural advantage in learning and understanding chemistry, which is full of abstractions that are remote from the material world. Simulations provide more-inclusive learning activities for students who are weak in logical-mathematical intelligence.

A second advantage of using simulations is that they are not limited by (for example) the quantised energies, integral masses and discrete expectation values of real atoms and molecules. Numerical experiments can be used to investigate the effect of continuously varying atomic mass, bond distance or any other property, from one value to another.

Finally, students are more familiar with spreadsheets than more advanced mathematical packages such as MathCAD, MAPLE, Mathematica and other symbolic algebra software. Use of these advanced packages presents additional learning hurdles for students and should be used only for advanced classes. Furthermore, spreadsheets are capable of a level of sophistication that is greater than commonly expected. This can be achieved without the use of MACROs.

Examples from the author's teaching are used to discuss the advantages of spreadsheet simulations for learning chemistry.

The Australian journal of education in chemistry

The article traces the history of the "Australian Journal of Education in Chemistry". The journal, which was founded in 1978, is the only refereed periodical that is wholly owned by the Royal Australian Chemical Institute (RACI). It is designed to improve the quality of chemistry teaching and learning in Australia. It was initially called "Chemeda: The Newsletter of the Chemical Education Division RACI". Overview of some article published in the journal is presented.
