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

Researchers in the educational field have investigated how a caring adult can best provide mentoring support to youth placed at risk and what functions a mentoring program should serve to promote healthy mentoring relationships. However, the perspective of mentors rarely has been sought to elicit their evaluation of a mentoring program or recommendations for programmatic change. The purpose of this article was to investigate the views of university students serving as mentors in high‐need high schools or community centers. We asked 49 students, primarily undergraduates across a range of liberal arts disciplines, who were participating in a university‐based service‐learning mentoring program for youth attending high‐poverty high schools: (a) what activities they engaged in with mentees, (b) how they benefited from the mentoring program, and (c) how they perceived the program and what recommendations they had for change. Findings revealed specific suggestions that mentoring program coordinators can adopt to address mentors’ concerns and promote sustained, durable mentoring relationships for youth. 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

This pilot study examined the effects of a short‐term music therapy program on the classroom behaviours of newly arrived refugee students who were attending an intensive ‘English as a Second Language’ secondary school. A cross‐over design with two five‐week intervention periods was employed with group music therapy sessions conducted one or two times per week. Data from the Behaviour Assessment Scale for Children were used to evaluate a range of positive and negative school behaviours. A significant decrease in externalising behaviours was found with particular reference to hyperactivity and aggression. No significant differences were found in other behaviours. Explanations and implications of these findings are discussed. 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

This article examines 3 papers presented before the Cincinnati Academy of Medicine by 19th-century physician Julia W. Carpenter. The article identifies 3 strategies Carpenter used to negotiate the incompatible rhetorical expectations for women and for physicians. The published records of academy discussions provide evidence for Carpenter's colleagues' reactions to each strategy, revealing the complexity of her rhetorical situation and demonstrating the complex links among rhetorical practice, professional identity, and a communicator's social position. 相似文献

Low-income single-mother students are disproportionately choosing to attend for-profit schools over community colleges when pursuing associate’s degrees and subbaccalaureate certificates. For-profit schools offer single mothers juggling school, employment, and family the benefits of accelerated degree programs along with enhanced convenience and streamlined student services. Community colleges can become a more appealing and feasible option for low-income single-mother students by adopting some of these characteristics while concurrently advertising their relative affordability and high level of academic rigor. 相似文献

Framing Quality: Annotated Video-Based Portfolios of Classroom Practice by Pre-service Teachers 总被引:1,自引:0,他引:1
In this paper we describe the use of peer learning teams creating annotated video-based portfolios to improve the quality of teacher–child interactions of undergraduate majors in early childhood and family studies. We used the intentional teaching framework (Hamre et al. in Handbook of early education. Guilford Publications, New York, 2012a) to create a course that moved students through the process of “knowing,” “seeing,” “doing,” and “reflecting & improving.” Forty-four undergraduate early childhood students formed eleven peer learning teams of four. We started the course by teaching the teacher–child interaction skills that are considered to be high-quality and linked to positive child outcomes (knowing). After learning to reliably identify (seeing) high quality instruction using the Classroom Assessment Scoring System, the students created video portfolios featuring their own adult-child interactions (doing). These portfolios, featuring short salient examples of six different dimensions of quality instruction, were posted to a website and shared with their peer learning team. Each team member then commented on the extent to which she or he believed the students’ example was high quality. The portfolios and the peer coaching learning team (PCLT) process have improved our ability to document change in interactions as well as the students’ abilities to see their own growth (reflecting & improving). Further, it allows us to tighten the connection between course content and practical application as well as providing us with an alternative to on-site supervision of practicum students, which can be challenging due to budget constraints. Finally, we hope that sharing this activity will encourage others to integrate video-based technology into their coursework as a means to demonstrate positive change in students’ learning. 相似文献

Research Findings: The objective of this study was to understand how two dimensions of parent–child book-reading quality—instructional and emotional—interact and relate to learning in a sample of low-income infants and toddlers. Participants included 81 parents and their children from Early Head Start programs in the rural Midwest. Correlation and multiple regression analyses were used to test the hypothesis that parental book-reading qualities interact and relate to children's concurrent cognitive and language scores. Exploratory analyses examined if patterns of relationships varied for families who had different home languages (i.e., English, Spanish). Results included that book-reading qualities and home language interacted to predict child scores. Practice or Policy: Findings suggest a need to further explore potentially complex patterns of relationships among parental book-reading behaviors and child learning for diverse families. Understanding these patterns could inform the development of culturally-sensitive intervention approaches designed to support high-quality shared book reading. 相似文献

A new vision of school counseling asserts that counselors must address all children and must orient counseling services toward the primary mission of schools: to educate young people and to support their healthy development. Two universities that are working to prepare new vision school counselors have changed their recruitment and selection procedures to attract increased numbers of candidates who can be optimally trained to fulfill the requirements of this vision. The authors describe criteria and procedures used to select graduate students who have the greatest promise of becoming leaders, advocates, and change agents in schools to promote student learning and achievement. 相似文献
