This article describes a simple and inexpensive hands-on simulation of protein folding suitable for use in large lecture classes. This activity uses a minimum of parts, tools, and skill to simulate some of the fundamental principles of protein folding. The major concepts targeted are that proteins begin as linear polypeptides and fold to three-dimensional structures, noncovalent interactions drive this folding process, and the final folded shape of a protein depends on its amino acid sequence. At the start of the activity, students are given pieces of insulated wire from which they each construct and fold their own polypeptide. This activity was evaluated in three ways. A random sample of student-generated polypeptides collected after the activity shows that most students were able to create an appropriate structure. After this activity, students (n = 154) completed an open-ended survey. Their responses showed that more than three-quarters of the students learned one or more of the core concepts being demonstrated. Finally, a follow-up survey was conducted seven weeks after the activity; responses to this survey (n = 63) showed that a similar fraction of students still retained these key concepts. This activity should be useful in large introductory-level college biology or biochemistry lectures.  相似文献

A sociocultural investigation with Year 8 secondary-school students experiencing marginalization and displaying signs of social and emotional difficulties in engaging fully with school life who participated in a mediated outdoor education programme was undertaken for this study. The findings indicate that there was a very statistically significant change in self-concept (p < 0.05) during the course of the programme. In addition, all participants reported positive results in relation to building trust, group cohesion, and emotional regulation with positive results on facing the challenges they experience daily within school. Moreover, 75% reported that they experienced positive gains in their family since beginning participation in the programme, and 100% stated that they had developed a deeper level of trust for the other group members.  相似文献

ABSTRACT

This study demonstrated how network usage logs such as those generated by the IBM Classroom Local Area Network Administration System (ICLAS) can be used to study student use of software available on a local area network. Software instrumentation was developed to convert ICLAS log files to a format (?.DIF) usable by spreadsheet and statistics software. Data on 163 students enrolled in an ‘Introduction to Computers in Education’ course during the Summer, 1992 session at the University of South Florida were compiled for exploratory analysis. Correlations of lab use time to course grade, change in knowledge, and change in attitude were performed. It was found that amount of lab use correlated significantly to general attitude toward computers, but that it did not correlate significantly to change in attitude toward school uses of computers or to change in knowledge of course topics.  相似文献

Conclusion The viewing of an educational film anf the recall of this viewing should constitute a satisfying learning experience so that the film’s message will be incorporated into a useful store of vicarious experience and remembered facts. Such learning is most likely to occur when those who write, direct, and edit a film have a clear understanding of the nature of the film’s audience and of what the film is expected to do to this audience. Knowing these things and to present his subject matter in the most interesting and satisfying manner possible. Here a long-time writer of educational films and television programs presents some thoughtful ideas on the design of instructional films for specific cudiences. Ralph R. White is a scenario writer with the Army Pictorial Center.  相似文献

This article explores the complex interplay of power between performativity and creativity agendas—a mutual tension that resides in British and Australian education. Accountability constraints and conflicting policy debates are problematised against the wider imperatives of similar government agendas. This ‘counterpoint’ of freedom and control has significant implications for pedagogy and, through accommodating performativity, teacher agency and professionalism are under threat. The authors propose a ‘rebalancing’ where pedagogy transforms from a site of struggle for control, to one where a higher trust is placed in teacher professionalism. The idea of ‘rebalancing pedagogy’ offers a way for teachers to navigate and be supported through the opposing demands of performativity and creativity. It acknowledges the importance of teacher agency and where teaching is judged against the characteristics of a systemic approach that facilitates the building of creative learning communities capable of supporting any curricula or content‐focused programmes in and beyond schools.  相似文献

The thesis of this essay is that globalization is a phenomenon that humankind must be educated for understanding as a process of global evolution. The new world evolving is being defined as requiring a new sense of collective cooperation amongst the peoples of the Earth, if we are to continue to exist on the planet. Educators are in the midst of and have an important role to play in this social and conscious evolution. One of our challenges is to explore the theoretical foundations for framing a new global education agenda. The assertion is that the theories of global, social, and conscious evolution of 20th century intellectuals and visionaries such as India’s Sri Ghose Aurobindo (1872-1950) and France’s Pierre Teilhard de Chardin (1881-1955) provide the foundation from which to construct a new global educational perspective.  相似文献

Abstract

In an increasingly data-driven world, facility with statistics is more important than ever for our students. At institutions without a statistician, it often falls to the mathematics faculty to teach statistics courses. This paper presents a model that a mathematician asked to teach statistics can follow. This model entails connecting with faculty from numerous departments on campus to develop a list of topics, building a repository of real-world datasets from these faculty, and creating projects where students interface with these datasets to write lab reports aimed at consumers of statistics in other disciplines. The end result is students who are well prepared for interdisciplinary research, who are accustomed to coping with the idiosyncrasies of real data, and who have sharpened their technical writing and speaking skills.  相似文献

Socioeconomically disadvantaged neighborhoods increase the risk for poor mental health among residents, yet protective factors may operate alongside risk. This study evaluated the influence of the prenatal neighborhood ethnocultural context on child behavior problems and maternal depressive symptoms. Prenatal maternal role expectations, prenatal culture-specific stress, and postpartum depression (PPD) symptoms were evaluated as mediators. Participants included 322 low-income, Mexican American mother-child dyads. Women (Mage = 27.8) reported on proposed mediators, maternal depressive symptoms, and child behavior problems at 4.5 years. Neighborhood Latinx concentration was obtained from census data. Higher Latinx concentration predicted fewer maternal depressive symptoms and child behavior problems, mediated through role expectations and PPD symptoms. Results suggest prenatal neighborhood context to impact later maternal and child mental health.  相似文献
