There are many assumptions about the ways in which textbooks and other learning and teaching support materials (LTSM) can contribute to improved learning outcomes in many international contexts. These can focus on ways that they can implement the school curriculum, often in lieu of good pedagogical practice. Drawing on case studies from Rwanda and South Africa, the complexity of the role of LTSM as part of classroom enactment is shown. The discussion suggests that there are enabling factors to this including support for teachers’ use of LTSM and the availability of materials to all learners. A framework is presented in which LTSM, teachers and learners can become equal partners in teaching and learning, but only when adequate language and other pedagogical support structures are provided. Conclusions consider the potential impact for LTSM use when it is elevated to a medium that is accessible and useful to both teachers and learners.  相似文献

Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes.  相似文献

Methodological problems, have limited the usefulness of findings from experiments into learning by discovery. By using programmed instruction materials, a within-class design, and other controls, an attempt was made to remove confounding. Two tasks were used: concept learning and principle learning. For each task, a separate 2x2x2 factorial design containing sixteen Ss in each cell was used. Independent variables were instructional method (egrule and ruleg), school grade (9 and 5), and intelligence (high and average). A set of eight different measures, involving retention, transfer, and ease of relearning, was used for each task. It was found that the egrule and ruleg methods did not differ significantly, and that interaction between instructional method and the other variables was low.  相似文献

Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns. Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation.

To understand the physical activity culture in the lives of Hong Kong Chinese children and their parents, 48 young people between the ages 9 and 16 and their parents, with different socio-economic backgrounds and geographical locations, were interviewed for this study. By applying Confucianism and postcolonialism, this study aimed to investigate the meaning of physical activity in the lives of Hong Kong children and their parents. The results showed that parents value physical activity as a factor which contributes to their children's well-being and provides balance to their life. There were differences though, in this attitude, for different age groups. Junior students (aged 9–12) expressed their interest in physical activities. However, older students (12 or above) in secondary school, think or are told that academic study is the most important aspect of their life and that physical activities are not a priority. When examining parents' and children's involvement in physical activity, the barriers to the parents' involvement in their children's physical activities included lack of time and a habitual sedentary lifestyle at home.  相似文献

Sequence learning in pigeons was studied in asimultaneous chaining paradigm: all stimuli and the opportunity to respond to each stimulus were available simultaneously. In contrast to the traditionalsuccessive chaining paradigm, a simultaneous chaining paradigm provides no differential feedback following each response (except the last). Subjects were first trained to perform on sequences of two (AB), then three (ABC), and then four colors (ABCD). Performance greatly exceeded that predicted by models of random choice. Generalization to novel arrays of three and four colors was complete. After training with a four-color sequence, the subjects were tested with subsequences consisting of all possible combinations of two and three of the four training colors (e.g., BD, AD, BC, ACD, BCD, etc.). The successful completion of these subsequences showed that the organization of the original sequence did not entail overt pecks to successive elements of that sequence. That subjects can respond accurately on nonadjacent subsets is not readily explained by a chaining theory, or by any theory that assumes that responding to element n provides a cue for responding to element n+1.  相似文献

Word reading and math computation scores were predicted from Wechsler Abbreviated Scale of Intelligence Full Scale IQ, 10 neuropsychological tests, and parent attention deficit hyperactivity disorder (ADHD) ratings in 214 general population elementary school children. IQ was the best single predictor of achievement. In addition, Digit Span contributed significantly to reading prediction, and the Developmental Test of Visual-Motor Integration (VMI) and Coding contributed to math prediction. The remaining neuropsychological test scores did not significantly improve achievement prediction. Exploratory factor analysis yielded a general ability factor (comprising the four IQ subtests, Digit Span, VMI, reading, and math), five factors made up solely of subtests from single measures (Wisconsin Card Sorting Test, Stroop Color and Word Test, Gordon Diagnostic System, California Verbal Learning Test, and ADHD ratings), a factor consisting of Grooved Pegboard Test and Coding, and a factor consisting of Symbol Search and Animal Naming Test.  相似文献

Students majoring in criminology and criminal justice are assumed to have more detailed and accurate knowledge about crime, criminal justice, and punishment practices than peers majoring in other disciplines. The purpose of this study was to examine if criminology/criminal justice majors were more or less punitive than students pursuing other majors at three universities using standard predictors of punitiveness that have not been consistently examined in previous research. The results indicate that criminology and criminal justice students are more punitive in the combined three‐campus sample and in two of the three‐campus samples considered separately.  相似文献

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that calculation complexity was predicted by long-term retrieval and working memory; calculation fluency was predicted by perceptual processing speed, phonetic coding, and visual processing; problem solving was predicted by fluid reasoning, crystallised knowledge, working memory, and perceptual processing speed. Younger students’ problem solving skills were more strongly associated with fluid reasoning skills, relative to older students. Conversely, older students’ problem solving skills were more strongly associated with crystallised knowledge skills, relative to younger students. Findings are consistent with the theoretical suggestion that broad cognitive processes play specific roles in the development of mathematical skills among children and adolescents. Implications for educational psychologists are discussed.  相似文献
