This paper describes the ways that students’ problem-solving behaviors evolve when solving multi-faceted, context-rich problems
within a web-based learning environment. During the semester, groups of two or three students worked on five physics problems
that required drawing on more than one concept and, hence, could not be readily solved with simple “plug-and-chug” strategies.
The problems were presented to students in a data-rich, online problem-based learning environment that tracked which information
items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like
entering an initial qualitative analysis of the problem into an online form. Students were not constrained to complete these
tasks in any specific order. As they gained more experience in solving context-rich physics problems, student groups showed
some progression towards expert-like behavior as they completed qualitative analysis earlier and were more selective in their
perusal of informational resources. However, there was room for more improvement as approximately half of the groups still
completed the qualitative analysis task towards the end of the problem-solving process rather than at the beginning of the
task when it would have been most useful to their work. 相似文献

Law enforcement officers, often the first professionals to come in contact with a victim of child sexual abuse, can either increase or decrease the traumatic impact on the child and the family at the time of disclosure. The model for a training program for police officers in handling cases of child sexual abuse outlined in this paper is divided into three sections. The first part is directed towards theoretical issues involved in this problem, including an explanation of the history and background of sexual abuse of children by adults and of the difference in the dynamics of extra- and intrafamilial sexual abuse. The second part consists of a detailed explanation of different types of sex offenses and of standard physical examinations of sexual abuse victims. Graded slides of physical trauma geared towards wound identification are paired with relaxation exercises. The third section focuses on special considerations when interviewing sexually abused children. The difference between interviewing and interrogation, specific questioning techniques, and the use of videotape is explained. Each part of this training procedure is followed by a question and answer period and small group discussions for the purpose of encouraging disclosure and better understanding of the officers' personal reactions to cases of child sexual abuse. 相似文献

The intent of this research was to investigate the experiences of eighth grade readers as they read nonfiction text on an iPad for academic purposes. We investigated reading strategies that students use to support their reading as well as what role iPad features played in the reading process. New literacies, metacognition and transactional theories informed the framework. Multiple data sources were used to triangulate findings and included (a) retrospective think alouds, (b) student iPad survey, (c) pre and post study student interviews, (d) Metacognitive Awareness of Reading Strategies Inventory and (e) student observations. Data for the collective case study participants focused on the identification of proficient readers who displayed confidence, competency, and control over text. Themes identified in the collective case studies included (a) reading comprehension strategies, (b) nonfiction features and (c) iPad features to support their reading of nonfiction on the iPad. 相似文献

Using statewide survey study data collected from more than 5,000 community college students, this study examined the impact of a preengineering curriculum on students' self-efficacy level after they entered rural community colleges. Project Lead The Way (PLTW), is a project-based learning curriculum for middle and high school students that strives to create a path to college and career success in STEM-related fields. In this article, the authors focused on comparing the probability of rating high self-efficacy among 86 community college students who participated in PLTW with students with no PLTW experience. The findings indicated that PLTW students have significantly lower probability of rating high self-efficacy compared to their non-PLTW counterparts. It might be that PLTW students rated their self-efficacy by comparing with a group of their close peers, who might be a group of academically high-ability students. This study provides implications for the unique, perhaps unintentional, peer effects of the project-based learning curriculum on the self-rating of students' self-efficacy. The findings highlighted the secondary-postsecondary nexus on STEM education, especially the importance of secondary programs that could positively influence the STEM educational pathways for community college students. 相似文献

Application of physiological methods, in particular electroencephalography (EEG), offers new and promising approaches to educational
psychology research. EEG is identified as a physiological index that can serve as an online, continuous measure of cognitive
load detecting subtle fluctuations in instantaneous load, which can help explain effects of instructional interventions when
measures of overall cognitive load fail to reflect such differences in cognitive processing. This paper presents a review
of seminal literature on the use of continuous EEG to measure cognitive load and describes two case studies on learning from
hypertext and multimedia that employed EEG methodology to collect and analyze cognitive load data. 相似文献
