The Role of Models and Analogies in the Electromagnetic Theory: A Historical Case Study

Despite its great importance, many students and even their teachers still cannot recognize the relevance of models to build up physical knowledge and are unable to develop qualitative explanations for mathematical expressions that exist within physics. Thus, it is not a surprise that analogies play an important role in science education, since students’ construction of mental models of abstract phenomena need to be rooted in some existing or previous experience in order to interpret more complex ideas. The present article focuses on some of these issues by analyzing some specific instances of the historical development of the electromagnetic theory. Using the mental models framework, the importance of mechanical analogies to understand some of the electromagnetic concepts are emphasized.     

A Method to Increase Student Interaction Using Student Groups and Peer Review over the Internet

A method of peer review for student groups is proposed. In this method, groups of students publish their assignments results over the Internet. A fellow student group reviews their work and publishes their findings (on the Internet). Finally, the two groups debate their points of view in front of the class. The debate and healthy competition among groups give the students a chance to learn how to give and receive criticism in a constructive way. This should increase the students' ability to interact and work in groups, an important skill for computer science professionals.     

The effectiveness of a marketing virtual reality learning simulation: A quantitative survey with psychophysiological measures

Virtual reality (VR) technology has been shown to be a promising teaching method in STEM subjects. Extending these findings, the current study is the first to develop and examine the feasibility of using a VR simulation in marketing (ie, a non-STEM subject). Specifically, the levels of immersion and three learning outcomes (learning attitude, enjoyment and performance) were compared between the marketing students who learned the same content through a VR simulation prototype versus a traditional static video presentation. Learning enjoyment was measured using facial electromyography, which served as a more objective measures for the feeling of enjoyment. Compared to the video condition, the results showed that VR resulted in a higher experience of immersion, learning attitude and learning enjoyment. Furthermore, immersion was found to fully mediate the positive effects of the VR simulation on learning attitude, but not enjoyment. Surprisingly, students in the video condition performed better on the knowledge-based test than those in the VR condition. The current study suggests that the current prototype of the VR simulations should be used as supplementary resource to increase the learning attitude and enjoyment, but not as a main teaching material to enhance knowledge-based performance in the marketing discipline.

Encouraging Example Generation: A Teaching Experiment in First-Semester Calculus

Abstract

Mathematicians use example generation to test and verify mathematical ideas; however, the processes through which undergraduates learn to productively generate examples are not well understood. We engaged calculus students in a teaching experiment designed to develop skills in productively generating examples to learn novel concepts. This article presents three student case studies. These case studies are representative of our findings and serve to summarize the activities we found useful. They also serve as examples of various student experiences during the teaching experiment. One student expressed a continued negative view to using example generation. Two increased in skills and experience and expressed positive changes in views.     

Distribution of School Knowledge and Social Reproduction in a Brazilian Urban Setting

The present study was designed to elucidate the ways in which the distribution of school knowledge contributes to processes of cultural and social reproduction. Three schools in the southern Brazilian city of Porto Alegre were studied for this purpose: a private institution serving an upper class clientele; a public school serving children of the middle class; and a public school attended by working‐class children. Two classrooms at each of the three schools were intensively observed during one semester. Teachers and staff were interviewed concerning their pedagogical views.

Patterns of instruction and control observed at the three schools suggest that children from different social classes receive substantially different kinds of schooling. The most obvious distinction in ideological discourse observed among staff members at the three schools concerns the existence of an explicit pedagogy endorsed at the private school and the concomitant absence of any such similar rationale at the other two schools.

The final sections of the paper discuss the implications of these findings for processes of cultural and social reproduction and their relation to relevant literature.     

The Struggle to Pass Algebra: Online vs. Face-to-Face Credit Recovery for At-Risk Urban Students

Students who fail algebra are significantly less likely to graduate on time, and algebra failure rates are consistently high in urban districts. Identifying effective credit recovery strategies is critical for getting students back on track. Online courses are now widely used for credit recovery, yet there is no rigorous evidence about the relative efficacy of online versus face-to-face credit recovery courses. To address this gap, this study randomly assigned 1,224 ninth graders who failed algebra in 17 Chicago public high schools to take an online or face-to-face algebra credit recovery course. Compared to students in face-to-face credit recovery, students in online credit recovery reported that the course was more difficult, were less likely to recover credit, and scored lower on an algebra posttest. There were no statistically significant differences by condition on any outcomes measured during the second year of high school (standardized mathematics test and algebra subtest scores, likelihood of passing subsequent math classes, cumulative math credits, or on-track rates). The benefits and challenges of online learning for credit recovery are discussed in light of the findings to date.
