A previous meta-analysis indicated that eight instructional factors--Questioning, Sequencing and Segmentation, Skill Modeling, Organization and Explicit Practice, Small-Group Setting, Indirect Teacher Activities (e.g., homework), Technology, and Scaffolding-captured the majority of successful intervention programs for adolescents with learning disabilities (LD). Most important was the Organization/Explicit factor, which contributed significant variance (16%) to effect size. This factor included two important instructional components: advance organization and explicit practice. In this article, we convert these findings into practical guidelines to direct instructional practice.  相似文献

Mobile devices are highly portable, easily distributable, substantially affordable, and have the potential to be pedagogically complementary resources in education. This study, incorporating mixed method analyses, discusses the implications of a mobile learning technology-based learning model in two public primary schools near the Mexico-USA border in the state of Baja California, Mexico. One school was located in an urban slum and the other in a rural village community. Empirical and ethnographic data were collected through a series of achievement tests, observations, surveys, and interviews involving 160 s grade school children recruited by convenience sampling. The general technology infrastructure, distinctive features of mobile learning to supplement literacy development, profound contextual phenomena arising from the two uniquely underserved communities, and social factors possibly influencing the educational experiences are discussed. The findings suggest that students in the rural village, seriously lacking educational resources and technology exposure, may have benefited substantially more from mobile technologies than urban school students possibly due to their relatively higher socio-economic status and higher parental involvement and interest in education. In contrast, there was no evidence of interaction with parental education levels, the experience of teachers or school principals, or the teacher’s perception or preparation of the technology. Overall, the mobile learning technology adoption was rapid, seamless, and actively driven by the students rather than the teacher. The challenges of the phenomenal migratory nature of most families in this unique geographical region are also discussed to benefit future studies.  相似文献

The transition to kindergarten represents an important developmental milestone for children and may pose unique challenges to children with disabilities, their families, and teachers. The primary goal of the current study was to investigate teacher concerns regarding the transition to kindergarten as well as teacher and parent-reported transition preparation practices and involvement for a sample of children with autism spectrum disorders (n = 19) and children with other developmental disabilities (n = 76). Teachers reported significantly more concerns for children in the ASD group than for children in the DD group, although there was no difference in total involvement in transition practices between groups. Although teacher and parent involvement in transition preparation was generally high, generic less individualized practices often were utilized. Study findings are discussed in the context of future research directions to help facilitate kindergarten transitions for young children with disabilities.  相似文献

In educational research, emotion has attracted substantial attention since the mid-1990s. While there are many studies of teacher emotion in educational change in the West, there is a remarkable dearth of such studies in China. This qualitative study attempts to address this issue by examining teachers?? emotional experiences in the national curriculum reform of senior secondary education in China. Results indicate that teachers revealed complex emotional responses to the reform. These emotions were related to teachers?? perceptions about the use of new textbooks, teaching approaches, and, more importantly, the uncertain changes in college entrance examinations. Three types of teachers with different emotions and professional identities are identified in the reform (i.e., the losing heart accommodators, the drifting followers, and the cynical performers). These findings highlight the Chinese perspective on teacher emotion and provide some implications for the management of curriculum reform and teacher emotion in the Chinese context.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are the most commonly diagnosed childhood disorders, and they frequently co-occur with each other. It has been found that students with comorbidity of ADHD and LD experience more difficulties in school. Even though the research interests in the comorbidity of ADHD and LD are increasing, there are inconsistent results in research studies and insufficient understanding of the comorbidity of ADHD and LD. This study attempts to grasp the progress of the studies in the comorbidity of ADHD and LD in Korea and to suggest the future directions for following research. A total of 90 studies published between 1987 and 2009 are examined. First, we analyze the studies that examined the learning problems of ADHD and then identify the characteristics of the learning problems in ADHD group. Afterwards, we investigate the studies that dealt with the attention problems of LD and then discuss the characteristics of the attention problems in LD group. Third, we identify the differences between ADHD and LD and synthesize the research findings. Finally, we analyze the studies conducted in conjunction with the comorbidity of ADHD and LD. On lightening the research of the comorbidity on three aspects, we find the research trend in Korea and provide the implications for future studies on the comorbidity of ADHD and LD. Furthermore, we suggest that it is important to identify comorbid conditions at the early stage, and it is necessary to conduct multidisciplinary research and international comparison research.  相似文献

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.  相似文献

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.  相似文献

Much of the research on social interaction in mainstreamed settings has focused on “reverse mainstreamed” or special environments in contrast, the present study observed 600 social interactions in 19 regular preschools. Three findings emerged: a) retarded children are substantially integrated into the emotional and social life of the peer group, but not fully integrated into peer group verbal life; b) there is an inverse relationship between teachers’ initiation of social interaction with retarded children and the degree to which the latter are integrated into peer group life; and c) teachers provide retarded children with more verbal enrichment and emotional protection than these children receive from their peer group. On balance, these findings are fairly encouraging, suggesting that to a considerable extent mainstreaming is working in preschool classrooms.  相似文献
