Traditional research on collaborative learning employs a “black box” approach that makes it difficult to gain a deeper understanding
of the differential effects of collaborative learning. To make the black box transparent, researchers have studied the process
of collaboration, in order to establish which interaction features are likely to make learning more effective and efficient
for group members. Although cognitive load theory has been developed in the context of individual learning situations, it
may provide a promising new way of looking inside the black box, assuming that students working in groups have more processing
capacity than students working individually. The aim of this article is to provide an overview of the process-oriented and
cognitive-load approaches to conducting collaborative learning research, to highlight their respective advantages and disadvantages,
and to suggest how they can be combined in order to address new research questions. 相似文献

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem‐based learning (PBL) curriculum. PBL is a well‐established student‐centered approach, and the authors have sought to examine if a student‐centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self‐directed learning questions. All IRSs were primarily directed by students. During two second‐semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student‐centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non‐IRS blocks. A student‐centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first‐year medical students.

Through multiple logistic regression modeling, this article explores the relative importance of risk and protective factors associated with learning disabilities (LD). A representative national sample of 6- to 17-year-old students (N = 1,268) was drawn by random stratification and classified by the presence versus absence of LD in reading, spelling, and mathematics according to ability-achievement discrepancies or low achievement levels. The dichotomous classifications were regressed on sets of explanatory variables indicating potential biological, social-environmental, and cognitive factors, problem behavior, and classroom learning behavior. Modeling revealed patterns of high risk for male students and students evincing verbal and nonverbal ability problems and processing speed problems. It was shown that, absent controls for cognitive abilities (such as provided by the ability-achievement discrepancy definition), definitions keyed to low achievement will substantially overidentify ethnic minority and disadvantaged students and will be confounded by significantly higher proportions of students who display oppositional and aggressive behavior problems. Alternatively, good learning behaviors uniformly provide substantial reduction in the risk for LD. 相似文献

The response to intervention of English language learners at risk for reading problems 总被引:1,自引:0,他引:1
The response to intervention (RTI) of English language learners identified as at risk for reading difficulties in the fall of first grade was examined at the end of first grade and at the end of second grade. Students at risk for reading problems were randomly assigned to intervention or control groups. Intervention students received supplemental reading intervention daily for 50 minutes in small groups from October to April. Students in the comparison condition received the school's existing instructional program for struggling readers. Criteria were established to determine adequate RTI at the end of first grade and at the end of second grade. The results indicated that more students who participated in the first-grade intervention in either Spanish or English met the established RTI standards than students who did not, and this finding was maintained through the end of second grade. 相似文献

A simple transfer function has been used to predict indoor temperature and humidity from outdoor climate. Using downscaled output from the Hadley Model (HadCM3) changes in indoor climate through to 2100 were predicted for an idealised unheated room at a number of European sites. The potential threats to paper and the risk of salt damage were predicted using damage functions. Although paper faces an increased risk in some temperate locations, salt weathering can increase or decrease dependent on location. Many future indoor climates may already exist at other locations, so communication throughout the heritage sector offers examples for the management of future challenges. Climate change is relatively slow so there is ample time for the adoption of good practices at these locations. 相似文献

For more than 150 years, the United States Government Printing Office (GPO), along with its Federal Depository Library Program (FDLP), has supported an informed citizenry and democracy by ensuring access and preservation to a broad swath of federal government information. This collaborative national public information program between local libraries and the national government, if it is to survive beyond its second century of service, must overcome profound challenges within a rapidly evolving complex of e-government policies and principles. The FDLP can (and must) find a way to serve its traditional values – permanent and public access to government information – that allows for growth and change within the demands of a dynamic electronic environment between the governors and the governed. 相似文献

The purpose of this study was to examine the adequacy of "multi-age" classification systems in youth sports with a specific focus on the unisex multi-age-groupings used by USA Swimming. In addition, we offer an analytical rationale for the multi-age-groupings and potential alternatives. We examined the top 100 US swim performances for three years (2005, 2006, and 2007) for girls and boys in 15 age-groups (7 to 20 years and a singular group of 21 years and older). Data for each age and sex were pooled over the three years and means were calculated for each of seven competitive swim events. Swim times differed among each age up to the 14-year age-group in girls (F (14,30885) = 183.9, P < 0.01, Cohen's d = 1.19-3.72, large effect) and 16-year age-group in boys (F (14,30885) = 308.7, P < 0.01, Cohen's d = 0.81-3.64, large effect) for all events. Age-related differences in swim times continued later in boys than girls likely due to differences between the sexes in timing of growth and maturation. Because of the differences in swim performance in contemporary multi-age-groups, stratifying swimmers by a single age is the best means to ensure competitive fairness and equality, although there is no rationale for swimmers under the age of 8 years to compete in separate unisex competitive groups. 相似文献

This study examined the nature, occurring contexts, and psychological implications of weight-related teasing in urban physical education programs. Semistructured interviews were conducted with 47 participants from a large urban school district. Data were analyzed using inductive analysis and constant comparisons. Most overweight adolescents experienced many different types of teasing in physical education. Victims of teasing felt hurt and experienced uncomfortable feelings due to social comparisons. Overweight students who were not teased reported a variety of reasons. Teachers lacked awareness of and strategies to handle teasing of overweight students. There is a need to implement preventive policies and rules to eliminate weight-related teasing and create inclusive physical education environments. 相似文献

Educators, not to mention philosophers of education, find themselves in a difficult position nowadays. They are confronted with problems such as which kind of values one would want citizens to embrace, or to what extent social practices of a particular group may differ from what is generally held. In this essay, Paul Smeyers and Yusef Waghid focus on postmodern critiques, in particular on the position of Michel Foucault as it is relevant for the debate on cosmopolitanism. The authors argue that Foucault's analysis of the self in relation to the other is somewhat contentious, as it seems to invoke an independent ethical self other than a social self. Smeyers and Waghid claim that a more nuanced position regarding this relation can be found in the work of Stanley Cavell. They conclude that encounters with the other should not be seen as a new kind of universalism or Foucauldian subjectivism, but rather as an opening that creates opportunities both for attachment and detachments, that is, for acknowledgment and avoidance. 相似文献
