South Africa’s readiness to integrate ICT into mathematics and science pedagogy in secondary schools
One of South Africa’s identified priorities is the implementation of ICT in education. To this end a phased implementation plan was initiated in 2004 for ICT to be implemented into schools across the country over eight years. During this time South Africa also participated in three international studies undertaken by the International Association for the Evaluation of Educational Achievement (IEA) focusing on ICT in Education. Each of these permitted the country to benchmark its progress in terms of other countries and their implementation of ICT in education. The latest study, SITES 2006 provides a useful set of indicators against which South Africa can evaluate its progress with regard to its implementation of ICT. This paper seeks to evaluate South Africa’s readiness to integrate ICT into mathematics and science classrooms. This was done using a number of indicators of “sustainable change” derived from SITES 2006 and then comparing these to countries such as Chile, Thailand and Norway, the former two with similar context and conditions and the latter with contrasting conditions. The findings reveal that whilst South Africa has made some progress since 1998 in terms of the implementation of ICT in education, that the majority of schools are still in their infancy regarding the acquisition of ICT and most of those who have access are still in the process of trying to integrate the ICT into their teaching and learning. It would appear that more fundamental needs in South Africa’s education system have dominated its priorities. 相似文献

Rats shocked once by a stationary, wire-wrapped prod mounted on the wall of the test chamber incorporated sand, wooden blocks, or commercial bedding material on the floor of the chamber into a defensive response. They moved the available material toward and over the shock prod in all three conditions, adapting the response topography to the particular demands of the available material. In the sand and bedding conditions, the rats buried the prod by pushing and spraying piles of the material with snout and forepaws, whereas, in the blocks condition they picked up the blocks with their teeth and placed them individually around the prod. In Experiment 2, the rats buried the shock prod with blocks even when they had to first carry the blocks to the prod from the back of the chamber. Thus, conditioned defensive burying is not a simple, reflexive response to objects paired with a painful stimulus: it is a complex behavioral sequence that can vary as a function of the availability of burying materials. 相似文献

OBJECTIVES: To examine the effects of different forms of family violence at two developmental stages by assessing a sample of 110 Israeli children, drawn from the case files of Israeli family service agencies, studied longitudinally in both middle childhood and adolescence. METHODS: Information about the children's adjustment was obtained from parents, teachers, and the children themselves when the children averaged 10.6 and 15.9 years of age using the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), Youth Self-Report (YSR), and Children's Depression Inventory (CDI). Information about the history of family violence was obtained from the mothers, fathers, children, and social workers. RESULTS: The results paint a mixed picture of the effects of family violence on children and adolescents. The relationship between concurrent behavior problems and abuse group varied by informant and study phase, although they were strongest when children were the informants. Predictions regarding the relationship between early abuse and later adjustment were only partially confirmed. Different informants did not agree about which groups of children were most adversely affected, there was little stability over time in the pattern of reported effects, and children were more likely than other informants to report levels of maladjustment that varied depending on recent or concurrent exposure to family violence. Many families changed their abuse status over time, and children who were new victims at follow-up had the most internalizing problems. Girls were found to be at more risk for internalizing and externalizing behavior problems than boys. CONCLUSIONS: Multiple informants are necessary to evaluate and assess the effects of family violence on children's behavior. Younger children may be more susceptible to the effects of family violence than older children, but problems manifest by some children may not carry over to adolescence. Changes in family and parenting practices, as well as in children's capacity to appraise and cope with family violence may help mitigate the adverse effects of family violence. 相似文献

The greater the dissimilarity between exteroceptive stimuli, the easier it is to discriminate between them. To determine whether a similar relationship holds for memories produced by reward events, rats in three runway investigations received trials in pairs, the number of food pellets (0.045 g) occurring on Trial 1 indicating whether reward or nonreward would occur on Trial 2. In each investigation, discriminative responding on Trial 2 was better the larger the difference in reward magnitude on Trial 1. This finding was obtained under a wide variety of conditions: for example, when the larger of two reward magnitudes on Trial 1 signaled nonreward on Trial 2 (Experiment 1, 10 vs. 2 pellets); when the smaller of two reward magnitudes on Trial 1 signaled nonreward on Trial 2 (Experiment 2, 10 vs. 2 pellets); and when the same magnitude of reward on Trial 1 signaled nonreward on Trial 2 (Experiment 3, either 5 pellets or 0 pellets). The findings obtained here indicate that the greater the dissimilarity between reward magnitudes, the greater the dissimilarity between the memories they produced and, thus, the easier it is to discriminate between them. It is suggested that the present results may provide a basis for understanding findings obtained in other instrumental learning investigations in which reward magnitude is varied. 相似文献

OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis. 相似文献

The purpose of this qualitative study was to examine teachers’ attitudes and experiences with coaching. This study was conducted in advance of a planned randomized controlled trial of a coaching intervention to better align the model with teachers’ needs and goals. Thirty-four K–5 general (n = 26), special education (n = 6), and educational support staff (n = 2) working in two high-poverty schools participated in focus groups. Interrater reliability between independent coders was high (К = 0.92; range: 0.76–1.0). Thematic analyses identified facilitators and barriers to teacher participation in the planned intervention and were used to improve upon the existing coaching model. Themes focused on advantages and disadvantages to coaching and characteristics of effective coaches and coaching models. Implications of findings for research and practice are discussed. 相似文献

This study investigates the efficacy of a social skills training program with seven mildly handicapped students across three school settings: regular classroom, special education resource room, and recess. It was found that social skills training generated improvement on both pre-post measures and behavior ratings. Improvements were maintained 2 weeks after treatment was discontinued for seven students. All students' performance generalized from resource room to regular classroom settings; only four students' performance generalized to the recess setting. 相似文献

Countless pregnant and parenting students come to college and university campuses across the country every year. According to the Urban Institute, more than 5.4 million parenting students were pursuing higher education as of December 2022. Whether a first-time freshman or a doctoral-level graduate student, these students are owed a robust support system by universities and colleges striving to achieve inclusive, developmental, and academic excellence. 相似文献
