Teaching Teamwork: Electronics Instruction in a Collaborative Environment

ABSTRACT

The Teaching Teamwork Project is using an online simulated electronic circuit, running on multiple computers, to assess students’ abilities to work together as a team. We pose problems that must be tackled collaboratively, and log students’ actions as they attempt to solve them. Team members are isolated from one another and can communicate only through an online chat channel, but modifications to the circuit made by any team member, insofar as they alter the behavior of the circuit, can affect measurements made by the others. We log all relevant student actions, including calculations (using an online calculator), measurements (using an online multimeter), inter-student communications, and alterations made by the students to the circuit itself. Automated analysis of the resulting data sheds light on the problem-solving strategy of each team, sometimes with surprising results.     

The body donation program at the Federal University of Health Sciences of Porto Alegre: A successful experience in Brazil

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists.     

A Remediation Program in an Urban College

Abstract

This article presents ten strategies instructors can use to get their students to take more responsibility for their learning. Suggestions are given about the importance of getting students to verbalize why they are taking the course, helping students get into the proper mindset for each class, and structuring assignments so students will be more likely to come to class prepared. Other suggestions include teaching students to look out for each other, behave responsibly when working in groups, and analyze their learning experiences. By teaching responsibility, as well as content, in our classrooms, we can enhance learning, raise the level of our classrooms, and produce more responsible members of society.     

Relations among student attention behaviors, teacher practices, and beginning word reading skill

The role of student attention for predicting kindergarten word reading was investigated among 432 students. Using Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scale behavior rating scores, the authors conducted an exploratory factor analysis, which yielded three distinct factors that reflected selective attention. In this study, the authors focused on the role of one of these factors, which they labeled attention-memory, for predicting reading performance. Teacher ratings of attention-memory predicted word reading above and beyond the contribution of phonological awareness and vocabulary knowledge. In addition, the relations between four teacher practices and attention ratings for predicting reading performance were examined. Using hierarchical linear modeling, the authors found significant interactions between student attention and teacher practices observed during literacy instruction. In general, as ratings of attention improved, better kindergarten word reading performance was associated with high levels of classroom behavior management. However, better word reading performance was not associated with high levels of teacher task orienting. A significant three-way interaction was also found among attention, individualized instruction, and teacher task redirections. The role of regulating kindergarten student attention to support beginning word reading skill development is discussed.     

Work–family relations among mothers of children with learning disorders

The study examined conflict and facilitation in work–family relations among working mothers of children with learning disorders (LD) or with typical development. The study also focused on three maternal personal resources (maternal anxious/avoidant attachment security, affect and sense of coherence) as antecedents of these work–family relations, and examined outcomes of such conflict and facilitation between the two life domains, as they affected patterns of close relationships within the family (child attachment and family cohesion). The sample included 96 mother–child dyads: 48 mothers and their children with LD; and 48 mothers and their typically developing children. Children’s ages were 8–12 years. All attended public elementary schools in urban areas of central Israel. Significant group differences emerged on mothers’ family to work conflict and on mothers’ work to family facilitation. Findings indicated that several maternal personal resources were antecedents of these relations and also contributed to differences in mother–child attachment relationships and family cohesion. Discussion focused on understanding work–family relations among these mothers of children with LD, as well as the influence of maternal personal resources on patterns of close relationships (i.e., child attachment, family cohesion).     

A constrained linear quadratic optimization algorithm toward jerk-decoupling cartridge design

Linear direct feed drives are widely used in machine tools, but an abrupt counter force from the secondary part will induce the jerk to the metro frame contacted with the linear motor and cause the vibration of auxiliary devices on it. The jerk-decoupling cartridge (JDC) provides a buffer to reduce such an impact. Design target for such a system includes both the tracking error and the jerk induced to the metro frame. To achieve both targets systematically, this work presents an integrated approach to efficiently determine parameters in the JDC and the position controller of the feed drive. The problem is firstly formulated as a nonlinear constrained optimization problem, which is then converted to a series of projection gradient optimization problems and step searching problems, which are either convex or linear. Thus, fast convergence of parameters are achieved within first several iterations. Through a series of simulation, the effectiveness of proposed methodology is verified.     

Social Movements in Brazil and their Educational Work

Using a distinction first proposed by Alain Touraine between historic and social movements, Ghanem's review of grassroots initiatives in Brazil argues that, despite differences in composition and aims, movements such as the landless rural workers, indigenous groups, and the women's movement in Brazil have attempted to shift the current socioeconomic order toward a new equilibrium – a process that is, however, not yet complete. In Ghanem's view, these movements are best described as historic movements. Addressing their educational aims, the author finds that they tend to fall into two types: (1) the self-provision of knowledge related to the set of problems that gave rise to their movement in the first place; (2) the striving for access to knowledge that is due to them as citizens and yet not given to them by the state. Often, social movements in Brazil are obliged to offer educational services through their own resources, services which are characterized by precarious conditions and which make the right to quality education still a distant dream.     

Comparative persuasive styles in Arabic and English: A study of the United Nations General Assembly Debate speeches

This study analyzed persuasive styles and tactics used in the United Nations General Assembly Debate speeches by Arabic and English speaking leaders. Past work has identified three persuasive styles: analogical, presentational, and quasilogical. The literature suggests that Arabs use analogical and presentational styles, while the “West” prefers the quasilogical style. Our results indicate that Arabs used the quasilogical style more often than English speakers. All speakers drew upon most of the tactics identified to strengthen their arguments. Finally, there has been a shift in the usage of some tactics for both sets of speakers over 30 years.
