Playing with a double-edged sword: Analogies in biochemistry
No full textAnalogy pervades our everyday reasoning. No situation we encounter is exactly like a situation we have encountered previously, and our ability to learn and survive in the world is based on our ability to find similarities between past and present situations and use the knowledge we have gained from past situations to manage current situations. Analogies can be powerful teaching tools because they can make new material intelligible to students by comparing it to material that is already familiar. It is clear, though, that not all analogies are good and that not all good analogies are useful to all students. In this study, I have used textbook analysis, classroom observations, student interviews and instructor interviews to determine the role that analogies play in biochemistry learning. Analogies are an important teaching technique in biochemistry classes, being used more often in both biochemistry classes and textbooks than they are in high school chemistry classes and textbooks. Most biochemistry students like, pay particular attention to, and remember the analogies their instructors provide; and they use these analogies to understand, visualize, and recall information from class. Even though students like and use analogies, they do not understand what analogies are or the mechanism by which they improve learning. For the students, analogies are simply any teaching technique that eases understanding, visualization, or recall. Instructors, on the other hand, have a good understanding of what analogies are and of how they should be presented in class; but they do not use analogies as effectively as they should. They do not plan, explain or identify the limitations of the analogies they use in class. However, regardless of how effectively instructors present analogies in class, this study indicates that, in general, analogies are useful in promoting understanding, visualization, recall, and motivation in biochemistry students at all levels. They would be even more useful if students understood what analogies are and how they can be used to improve understanding of biochemical concepts
Affective Dimensions in Chemistry Education
Get PDFThis is a unique resource for those wishing to address the affective domain as they research and solve problems in chemistry education. Contributions by world-leading experts cover both fundamental considerations and practical case studies. This work fills a gap in the literature of chemistry education, which so far has focussed mainly on the cognitive domain. The affective domain refers to feelings-based constructs such as attitudes, values, beliefs, opinions, emotions, interests, motivation, and a degree of acceptance or rejection. It can affect students\u27 interest in science topics and their motivation to persevere in learning science concepts
Investigating the trajectories of academic staff who identify as DBER scholars
Get PDFOne of the growing areas of research in Australia is the discipline-based education research (DBER) field. In 2012 a National Research Council report stated “[DBER is a] vital area of scholarship [with] potential to improve undergraduate science and engineering education” (National Research Council, 2012, p. 1), meeting recommendations given by the Chief Scientist of Australia (2014) to improve the education of STEM graduates.
The primary intent of this study was to collect the motivations, journeys and trajectories of DBER researchers and find factors that can lead to supporting the growth and retention of these scholars. Given the regional differences in academic landscapes between continents, we have chosen to focus (for now) on the Australian DBER community. Additionally, we know representation within our teaching faculty has direct and measurable impact on the students themselves. As such, we have also explored the diversity of backgrounds of those who participated alongside their perceptions of the diversity seen within the Australian DBER community.
To achieve the above aims, a series of interviews were undertaken with Australian academics who identify as being a part of the DBER community. The population represented was across a range of experience levels, from early career to senior, as well as multiple gender identities and varied academic pathways. In this presentation, the outcomes of analysing this data will be used to describe the types of academics that are becoming DBER researchers in Australia, as well as the initial motivations and pathways that have led them to this point in their careers.

What do biochemistry students pay attention to in external representations of protein translation? The case of the Shine–Dalgarno sequence
Get PDFBiochemistry instructors often use external representations—ranging from static diagrams to dynamic animations and from simplistic, stylized illustrations to more complex, realistic presentations—to help their students visualize abstract cellular and molecular processes, mechanisms, and components. However, relatively little is known about how students use and interpret external representations in biochemistry courses. In the current study, variation theory was used to explore the potential for student learning about protein translation from a stylized, dynamic animation. The results of this study indicate that students learned from this animation, in that they noticed many critical features of the animation and integrated those features into their understandings of protein translation. However, many students also focused on a particular feature of the animation, the Shine–Dalgarno sequence, that their instructors did not feel was critical to promote an overall understanding of this metabolic process. Student attention was focused on this feature because of the design of the animation, which cued students to notice this feature by significantly varying the appearance of the Shine–Dalgarno sequence

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
