Science students increasingly need programming and data science skills to be competitive in the modern workforce. However, at our university (San Francisco State University), until recently, almost no biology, biochemistry, and chemistry students (from here bio/chem students) completed a minor in computer science. To change this, a new minor in computing applications, which is informally known as the Promoting Inclusivity in Computing (PINC) minor, was established in 2016. Here, we present the lessons we learned from our experience in a set of 10 rules. The first 3 rules focus on setting up the program so that it interests students in biology, chemistry, and biochemistry. Rules 4 through 8 focus on how the classes of the program are taught to make them interesting for our students and to provide the students with the support they need. The last 2 rules are about what happens “behind the scenes” of running a program with many people from several departments involved. 相似文献

The aim of the study was to describe, categorise and analyse students’ (aged 14–16) processes of scientific inquiry in biology and chemistry education. Therefore, a theoretical structure for scientific inquiry for both biology and chemistry, the VerE model, was developed. This model consists of nine epistemological acts, which combine processes of scientific thinking and inquiry methods. Based on the theoretical structure, a paper-and-pencil test was developed to investigate the students’ abilities in the acts of scientific inquiry. Each of the nine acts was operationalised to generate multiple-choice items. For each act, ten items were constructed. In total, ninety items per subject were tested in a field study to evaluate their psychometric quality. The article focuses on the outcomes for testing in biology. In biology, 537 students were tested with a paper-and-pencil test, following a multi-matrix design in which each student solved twenty-seven items. Data from 260 students have been analysed so far. Seventy-five items showed satisfactory item characteristics. The distribution of the items’ difficulties fits the students’ abilities appropriately. We conclude that theory-driven epistemological acts can be operationalised in tasks that assess students’ abilities in scientific inquiry. 相似文献

An understanding of physical chemistry principles enhances student understanding of biochemical phenomena; however, the application of these principles to biological examples is frequently missing in the standard undergraduate physical chemistry curriculum. The topics of protein folding and stability are based in thermodynamics and can serve as a vehicle for presenting essential thermodynamics in a context that is highly relevant to undergraduate biochemistry majors. The outline of a course that replaces the standard thermodynamics offering in physical chemistry is described. The protein folding literature is used to illustrate thermodynamic concepts in this course and students are expected to read and comprehend the assigned literature. The course is offered as a separate biophysical chemistry course for B.S. Biochemistry majors; however, elements of this course may be useful in crafting a more standard thermodynamics course for B.S. Chemistry majors in chemistry departments seeking to fulfill ACS guidelines for approved B.S. Chemistry majors. 相似文献

Chemical biology graduate programs that are jointly organized by chemistry and life science departments can offer a stimulating 'bicultural' training environment for students from diverse backgrounds. However, communication, flexibility and responsiveness are crucial for effectively structuring such programs. 相似文献

Movies depicting science-related issues often capture the attention of today's youth. As an instructional tool, movies can take us beyond the drama and action and thrilling scenes. In this article we share our experiences of using the movie Eight Below as a centerpiece for developing high school students’ understanding of basic chemistry concepts. In addition to the science concepts developed using the context of the movie, we engaged students in thinking about the ethical dilemmas embedded in the movie. 相似文献

Plants are an integral part of nature. Many plant species in almost any part of the world are under serious threats due to various reasons such as deforestation, pollution–of air, water and soil–caused by industrialisation, overgrazing and rapid population growth. It is likely that people have strong positive attitudes towards conservation of plants. This study investigated the effectiveness of an instructional approach based on integration of botany with chemistry and art on students’ attitude towards plants. This study was carried out in a science summer school for 10–12-years-old students (N = 49) in Turkey. The Plant Attitude Questionnaire was used as pre-test and post-test to assess the effects of the instruction on the students’ attitudes towards plants. Moreover, the participating children were asked to keep journals throughout the instruction. The children’s journals served as a data collection tool. The findings of the study indicated that integration of botany with chemistry and art is a good way to support children’s positive attitudes towards plants, particularly for an instructional approach based on the integration of plants with various disciplines to support children’s interest and enjoyment of plants. Also, this approach could offer children opportunities to understand the importance of plants in the living environments of humans and other organisms, and material benefits from plants in industry. 相似文献

Learning about the water situation in other regions of the world and the devastating effects of floods on drinking water helps students study science while learning about global water quality. This article provides science activities focused on developing cultural awareness and understanding how local water resources are integrally linked to the quality of the world's water supply. After reading and discussing a case study highlighting one water situation facing the people of Kenya, students explore water sanitation and testing methods, including solar pasteurization and the Colilert test for total coliform bacteria and Escherichia coli. These investigations are relevant to inquiry-based water quality labs for high school biology, chemistry, and environmental science. 相似文献

Teaching college students about the nature of science should not be a controversial exercise. College students are expected to distinguish between astronomy and astrology, chemistry and alchemy, evolution and creationism. In practice, however, the conflict between creationism and the nature of science may create controversy in the classroom, even walkouts, when the subject of evolution is raised. The authors have grappled with the meaning of such behaviors. They surveyed 538 students in a public, liberal arts college. Pre/post course surveys were analyzed to track changes in student responses to questions that were either consistent or inconsistent with the Theory of Evolution after a semester of instruction in a college biology or zoology course in which evolution was taught. Many students who were initially undecided about issues regarding evolution had shifted in their viewpoints by the end of the course. It was found that more education about the evidence for and the mechanics of evolutionary processes did not necessarily move students toward a scientific viewpoint. The authors also discovered a "wedge" effect among students who were undecided about questions pertaining to human ancestry at the beginning of the course. About half of these students shifted to a scientific viewpoint at the end of the course; the other half shifted toward agreement with statements consistent with creationism. 相似文献

The lunar samples from Apollo flights 11 through 17 provided the students of chemical evolution with an opportunity of examining extraterrestrial materials for evidence of early prebiological chemistry in the solar system. Our search was directed to water-extractable compounds with emphasis on amino acids. Gas chromatography, ion-exchange chromatography and gas chromatography combined with mass spectrometry were used for the analysis. It is our conclusion that amino acids are not present in the lunar regolith above the background levels of our investigations. 相似文献

The changing landscape of education in biochemistry and molecular biology presents many challenges for the future, for students and educators alike. The exponential increase in knowledge, the genomics, proteomics and computing revolutions, and the merging of once separate fields in biology, chemistry, physics and mathematics, mean that we need to rethink how we should be preparing today's science undergraduates for the future. What do we need to change, and how will we implement it? 相似文献

Review: Biodegradation as a biotechnological model for the teaching of biochemistry. A knowledge of waste treatment and the biodegradation processes involved is necessary for undergraduates in agriculture, chemistry, biology, food technology, etc. Courses in these subjects must make adequate provision for such instruction. In this article, we suggest a theoretical and practical study of composting, which stimulates the interest of the students in metabolic pathways involved in this, and other, biotechnological processes. 相似文献
