This paper briefly surveys current work in the emerging area of Computer Supported Collaborative Learning (CSCL) and describes how the technology can be extended to exploit communication between computers. A number of applications which might make use of network support, distributed CSCL, are reviewed and a simple prototype distributed CSCL application is described and evaluated. The work has highlighted issues concerning the value, viability and development of distributed CSCL software. It would appear that valuable opportunities for the development of such software exist but it is unclear how these applications might be developed using existing hardware. Conclusions are presented regarding the future of network supported CSCL.  相似文献

A contingency contract procedure was used to reduce truancy in a 13-year-old learning-disabled subject. The subject received a daily amount of trading stamps contingent on school attendance. Results showed a significant decrease in truancy from three to four days per week to less than one per week. A reversal design indicated that truancy could be controlled by the contingency procedure.  相似文献

This study explores how teachers developed and critically evaluated a range of teaching strategies that could support the discussion of a socio-scientific issue (SSI) that had the potential to be controversial. The issue was stem cell research and six New Zealand teachers of senior biology students (grades 12/13) took part in an action research project that was situational, collaborative and self-evaluative. The focus of the research was to identify communication barriers that interfered with classroom discussion and how teachers could help students cross cultural borders when they discussed SSIs that were outside their life worlds. The barriers to communication were access to relevant science knowledge, religion, language, an inability to question issues and cultural expectations of girls. Teachers trialled and adapted two discussion strategies, ‘Drawing the Line’ and ‘Diamond Ranking’ that provided a vehicle for their students to explore and discuss this issue from a range of perspectives. These discussion strategies enabled their students to take part in a dialogue where reciprocal conversation could occur because they had opportunities not only to explore their own perspectives but also other people's viewpoints.  相似文献

This paper reviews the results of a citation analysis conducted to determine the extent of references to African American scholarship in American criminology texts published between 1918 and 1960. The analysis showed that African American graduates from the University of Chicago's “Chicago School”, including Charles Johnson, E. Franklin Frazier, Monroe Work, and Earl R. Moses, were cited most often. They were usually cited in discussions of either race or culture areas and crime. African American scholars' discussions of the effects of social, economic, and political conditions such as slavery, segregation, racism and oppression on crime and criminality, especially among African Americans, were generally not cited. These findings suggest that while claims that African American scholarship cannot be found in mainstream publications might be somewhat overstated as they relate to early American criminology texts, the most important themes found in the writings of African Americans were excluded.  相似文献

The classroom environment influences students’ academic outcomes, but it is often students’ perceptions that shape their classroom experiences. Our study examined the extent to which observed classroom environment features shaped perceptions of the classroom, and explained levels of, and changes in, girls’ motivation in junior secondary school science classes across two school terms. Girls have been found to feel less capable than boys and to under-participate in science classrooms, even though their achievement levels are similar. Four teachers and five of their classrooms of students (N = 52) reported their perceptions of the classroom environment, and trained observers rated the ‘actual’ classroom environment. Students also completed questions regarding their motivations for science at both time points. Hierarchical linear modelling showed that students’ perceptions of classroom structure were very important and exerted significant influence on science motivations. All of the six observed classroom dimensions affected students’ extrinsic utility value, via perceptions of structure. Other classroom dimensions showed particular patterns of relationship with motivations. Teachers’ perceptions of the classroom environment were often more positive than those of the students, which is congruent with previous research. The findings have implications for retaining girls in science and, thereby, addressing the gender gap in science-related vocations.  相似文献

About half of 2,581 low-income mothers reported reading daily to their children. At 14 months, the odds of reading daily increased by the child being firstborn or female. At 24 and 36 months, these odds increased by maternal verbal ability or education and by the child being firstborn or of Early Head Start status. White mothers read more than did Hispanic or African American mothers. For English-speaking children, concurrent reading was associated with vocabulary and comprehension at 14 months, and with vocabulary and cognitive development at 24 months. A pattern of daily reading over the 3 data points for English-speaking children and daily reading at any 1 data point for Spanish-speaking children predicted children's language and cognition at 36 months. Path analyses suggest reciprocal and snowballing relations between maternal bookreading and children's vocabulary.  相似文献

Children learning English as an additional language (EAL) often experience difficulties with reading comprehension relative to their monolingual peers. While low levels of vocabulary appear to be one factor underlying these difficulties, other factors such as a relative lack of appropriate background knowledge may also contribute. Sixteen children learning EAL and 16 of their monolingual peers, matched for word reading accuracy, were assessed using a standard measure of reading comprehension and an experimental measure of reading comprehension for which relevant background knowledge was taught before assessing understanding. Tests of receptive and expressive vocabulary were also completed. Results confirmed lower levels of reading comprehension for children learning EAL for both standard and ‘background’ controlled measures. Analysis of comprehension by question type on the experimental measure showed that while both groups made use of taught knowledge to answer inferential questions, children learning EAL had specific difficulties with both literal questions and questions requiring the interpretation of a simile. It is suggested that relevant background information should be used to facilitate children's text comprehension. Furthermore, several factors, especially vocabulary differences, but also text search strategies, context use and comprehension monitoring skills, may contribute to the comprehension difficulties experienced by children learning EAL.  相似文献

The most recent Program for International Student Assessment (PISA) (2009) mathematical literacy results provide evidence that in Western English-speaking countries, including Australia, the gender gap in achievement appears to be widening in favour of males. In the study reported in this article, the aim was to explore the effects of gender, school type (a measure of socioeconomic background), school learning setting and geographic location on mathematics performance amongst the highest achievers (top 2 %) in the grade 12 Victorian Certificate of Education (VCE) mathematics subjects based on results reported in a metropolitan newspaper. The analyses revealed that over the period 2007–2009, males, students from higher socioeconomic backgrounds and those attending metropolitan schools predominated amongst the highest achievers in all three VCE mathematics subjects. Students in single-sex settings, particularly males, were also over-represented. For each factor, the dominance was more pronounced as the level of difficulty of the mathematics subject increased.  相似文献

This paper summarises research conducted into the issue of gender differences within primary school bullying. The study focused on the extent and nature of gender differences and teachers' perceptions and experiences of these differences. Primarily, the research shows that anti-bullying strategies need to be more focussed on girl's experiences of bullying. Within the study, the teachers' identification of boys bullying appeared to be in line with both well-documented gender differences and those reported by the pupils in the study. However, the teachers' appear to be less able to identify girls' involvement in bullying.  相似文献
