Chemistry Education for Sustainability: Assessing the chemistry curricula at Cardiff University

Rodrigo Lozano, Mary Katherine Watson   184-192
[+]
As more universities become interested in, and engaged with, sustainability, there has been a growing need to assess how their curricula addresses sustainable development and its myriad issues. Different tools and assessment exercises have looked at course descriptors. This paper presents the Sustainability Tool for Assessing Sustainability in Universities Curricula Holistically (STAUNCH, Trade mark) assessment of the School of Chemistry, Cardiff University. The results indicate that STAUNCH -Trade mark- can be instrumental in identifying courses that more adequately capture the breadth and depth of sustainability and exhibit high contribution scores. The curricula assessment can help university leaders and directors of teaching and learning better understand where they should engage in changes to make chemistry education more sustainability-oriented, and, ultimately, to have the greatest impact in helping make societies more sustainable. Overall, STAUNCH -, Trade mark- can provide a systematic method for evaluating the strengths and weaknesses of the chemistry curriculum for the purpose of devising curriculum reform strategies to promote student sustainability learning. Keywords: sustainability in higher education, curricula assessment, STAUNCH tool, Cardiff University, chemical education

EMERGENT TOPICS ON CHEMISTRY EDUCATION

Human durability and chemical education

Carlos Amador Bedolla   193-198
[+]
Two hundred years of intense economical growth, centrally driven by abundant access to sources of inexpensive energy, have allowed the establishment of a social paradigm that has directed the development of all social, economic, educational, scientific and technological aspects of our society. However, during the past fifty years, evidence has accumulated of our displacement towards several planetary boundaries as a result of the effects of the application of this paradigm, thus alerting us of the impossibility of its continuance. Sustainability science is a rational attempt of adopting an alternative paradigm that allows deviating from these planetary boundaries. The relative autonomy of universities and its influence on the creation of cultural capital make them a forceful participant in the diffusion and application of the science of sustainability. Chemistry has an important role in solving some of the most urgent problems of our present situation. KEYWORDS: sustainability science, planetary boundaries, sustainability in higher education and scientific research

EMERGENT TOPICS ON CHEMISTRY EDUCATION

Sustainability science: A New Knowledge Domain to which chemistry and chemistry Education are contributing

Daniel Gil Pérez, Amparo Vilches   199-206
[+]
The most diverse knowledge domains are currently contributing to the treatment of socio- environmental problems. Many papers and books have been published in the fields of Green Chemistry, Industrial Ecology, Environmental Engineering, Green Economy (low in carbon), Environmental Education, etc. But very recently it has been understood that these contributions are insufficient and that we need a Sustainability Science that integrates all of them. This paper studies the emergence of this new field of knowledge and research, which explicit aim is to contribute to the transition to a sustainable society. Keywords: sustainability science, education for sustainability, green chemistry, scientific revolution

EMERGENT TOPICS ON CHEMISTRY EDUCATION

Science, Technology, Environment, Society (STES) Literacy for Sustainability: What Should it Take in Chem/Science Education?

Uri Zoller   207-214
[+]
Ensuring sustainability requires a paradigm shift in conceptualization, thinking, research and Science education, particularly concerning the science-technology-environment-society (STES) inter-faces. Consequently, STES literacy requires the development of students capabilities via higher-order cognitive skills (HOCS)-promoting teaching, assessment and learning strategies. Striving for sustainability and the consequent paradigms shift, from unlimited growth to sustainable development, makes the corresponding paradigms shift in science, environmental and technology engineering education, from algorithmic teaching to HOCS learning, to become unavoidable. The identified paradigms shift reflect the ever-increasing social pressure towards more accountable, socially- and environmentally-responsible sustainable action. Concomitantly, this pressure constitutes the driving force for STES education for sustainability. This requires HOCS for responsibly dealing with multi-dimensional, socio-economical-technological-environmental systems. Our research findings and educational practice suggest, that, although the road to STES literacy for sustainability is rocky, it is educationally feasible and, therefore, attainable.

TO TAKE THE DUST AWAY

John William Draper

Jaime Wisniak   215-223
[+]
John William Draper (1811-1882), a physician, did extensive work in the nature of radiant heat, in proving that the rays of all wavelengths are capable of producing chemical changes, in the determination on the nature of the rays absorbed in the growth of plants in sunlight, and on the interpretation of capillary phenomena in physiology and in plant growth. He used intensively and smartly the science and art of photography, then in its infancy, to give visual proofs of his results. He was one of the first to photograph a human face, the moon, and the solar spectrum. Keywords: Optics, photochemistry, photography, phosphorescence, tithonic rays, spectrum, capillary phenomenon, osmosis, endosmosis.

WOMEN AND CHEMISTRY

Marie Sklodovska Curie and radiactivity

Adela Muñoz Páez   224-228
[+]
There is no other woman in the history of science better known than Marie Curie, the only one that everybody knows. She was the first Professor at the Sorbonne, the University of Paris after more than six hundreds years, the first woman to obtain a Nobel Prize, the first scientist to obtain a second. But above all these honours, Marie was a passionate person, whose curiosity and spirit of adventure keep her alive beyond the limits of her strength. It is astonishing how there are still some persons, usually men, that still consider her as an assistant of her husband, neglecting the relevance of her discovery, the radioactivity. It is even more difficult to understand how distorted is the picture of her that had reached us, that of a sad women, wearing always black dresses. And Marie was just the opposite: a lively and passionate woman, who devoted her life to science as everybody knows, but did many other things as well: fought to defend her country, and loved passionately her daughters and the men she felt in love with, specially her husband. Keywords: Marie Curie, Pierre Curie, Radiactivity, polonium, radium, Henry Becquerel, Irene Joliot-Curie

EDUCATIONAL ASSESSMENT

Positioning for Teachers of Science in the Evaluation of Learning: An Approach to its Subjectivities

Osbaldo Turpo-Gebera   230-236
[+]
Pedagogical and epistemological criteria of science teachers to guide their thoughts and educational activities are evident through the recognition of the positions assumed, as expressions of subjectivity teaching. Teachers in this discourse, reveal a state of confusion over terminology and explanatory interpretive frameworks that support their views and assessment practices, which appear as traditional and innovative, without distinction. Such interventions express the reduced effectiveness of teacher training process changes promoted, and conversely, a series of embarrassments in making pedagogical decisions. KEY WORDS: Assessment of learning. didactic of science. Evaluative perspectives. Teacher subjectivity.

Experimental methods that allow the study of macromolecules of life: history, fundamentals and perspectives

Oscar Gregorio-Ramírez, Julián M. Peña-Castro, Blanca E. Barrera-Figueroa   237-246
[+]
Nucleic acids and proteins comprise a network of biomacromolecules that store and transmit information sustaining the life of the cell. The study of these mechanisms is a field called molecular biology. The development of this science has always been paired with technical advances that allow breaking through methodological barriers in order to test novel hypothesis. Among available methods for molecular biologists, five stand: electrophoresis, sequencing, cloning, blotting and polymerase chain reaction. Their impact reaches genetics, medicine and biotechnology. Here, the historic relevance, technical grounds and current trends of these five essential methods are reviewed. The review intends to be useful both for students and professional scientists who seek to acquire advanced knowledge on the value of these methods to probe the molecular mechanisms sustaining life. Keywords: biomacromolecules, genetic information, genomics, transcriptomics, proteomics.

ICT AND CHEMICAL EDUCATION

Concepts of heat and work in an electronic forum. Effect of computer self-efficacy

Martín Enrique Durán-García, Emilse Emperatriz Durán-Aponte   247-254
[+]
The purpose of this study was to describe the performance in an electronic forum activity on the concepts of work and heat and their relationship with computer self-efficacy and other variables, with the aim of providing tools that incorporate the use of ICT in the teaching of thermodynamics . 34 university students participated in Mechanics and Aircraft Maintenance Technology. We used the Computer Self-Efficacy Inventory (IAC) adapted by Peinado and Ramirez (2010). Significant relationships were found between performance on the electronic forum and computational efficacy subscale and between basic skills and performance in the electronic forum. The results suggest the need to take into account the knowledge about electronic resources held by students to reinforce knowledge or training in new technologies, given that the more able to feel, get better results in activities that involve the use of the computer. Keywords: computer self-efficacy, an electronic forum, the teaching of thermodynamics, meaningful learning.

ICT AND CHEMICAL EDUCATION

Virtual Campus and Facebook in the College Environment. Allied or Enemy in Teaching and Learning Processes?

Gisela Celeste Muscia, Esteban Ariel Ugliarolo, Daniela Soledad Mansilla   255-259
[+]
Our students live in a new era of communication. For many years chemists have used technology for teaching and learning at different levels of education. The use of virtual platforms is a valuable educational tool. The aim of this paper is to analyze the use of virtual platforms for students enrolled in the Organic Chemistry II course, of the careers of Pharmacy and Biochemistry, University of Buenos Aires. We have compared the use of the Virtual Campus and Facebook groups. A sample of 110 randomly selected students participated in this research. The 100% of students were registered on the campus of Organic Chemistry II and the 80% was a member of a related Facebook group. The 90% of the students used some of these technological tools as a means to support their questions. Moreover, the 67% of respondents prefer Facebook as a means of communication. The 64% of students felt that Facebook was the means by which they obtained a rapid response. The results indicate that students use virtual platforms as a support tool in the learning process. Keywords: Undergraduate Students, Organic Chemistry, Virtual Platforms, Facebook, Virtual Campus
