The study examined the sustained effects of methylphenidate on reading performance in a sample of 42 boys, aged 8 to 11, with attention deficit-hyperactivity disorder (ADHD). Two subgroups were formed based on the presence or absence of co-occurring conduct disorders. Subjects were selected on the basis of their positive response to methylphenidate as determined in a series of original medication trials (Forness, Cantwell, Swanson, Hanna, & Youpa, 1991). For the purpose of this study, subjects were placed on their optimal dose of medication for a 6-week period and then tested on measures of oral reading and reading comprehension equivalent to those used in the original trials, retested after a week without medication (placebo), then tested again the following week after return to medication. Only the subgroup with conduct disorders responded, and this response was limited to reading comprehension improvement in only those subjects who also demonstrated improvement in oral reading on original trials. No response differences were found between subjects with or without learning disabilities.  相似文献

Opportunities for American Indian youth to meaningfully engage in school-based science, technology, engineering, and mathematics (STEM) experiences have historically been inadequate. As a consequence, American Indian students perform lower on standardized assessments of science education than their peers. In this article we describe the emergence of meaning for students—as well as their community—resulting from Indigenous culturally-based STEM curriculum that used an American Indian tradition as a focal context. Specifically, the game of snow snakes (Gooneginebig in Ojibwe) afforded an opportunity for STEM and culturally-based resources to work in unison. A case study research design was used with the bounded case represented by the community associated with the snow snake project. The research question guiding this study was: What forms of culturally relevant meaning do students and the community form as a result of the snow snake game? Results indicate evidence of increased student and community engagement through culturally-based STEM experiences in the form of active participation and the rejuvenation of a traditional game. Implications are discussed for using culturally-based contexts for STEM learning.  相似文献

Many theories on college retention recognize the significance of student satisfaction as a positive factor in students’ persistence. Yet, there are few theories that address the relationship of degree program satisfaction to study behaviour and dropout. This paper explores the impact of degree program satisfaction on academic accomplishment and dropout. The impact of degree program satisfaction was studied within a multitheoretical framework. The results of the study show that student accomplishment not only depends on differences in academic ability but also on degree program satisfaction. Decreased degree program satisfaction appears to diminish both study motivation and study behaviour. The authors discuss some implications for current educational practice.  相似文献

3 hypotheses were tested concerning the developmental relation between children's concepts of physical uncertainty and their comprehension of a speaker's uncertainty. 2 cognitive tasks of physical uncertainty were used to assign 56 subjects (aged 5-4 to 17-11) to 1 of 3 cognitive stages. 2 tests for comprehension of speaker uncertainty were administered to all participants. The results indicated that cognitive stage was related to (a) comprehension that a speaker could be uncertain, (b) comprehension that uncertainty could be expressed in different degrees or magnitudes, and (c) the internal consistency of judgments made about the relative degree of uncertainty conveyed by an utterance. These findings are interpreted as evidence for the position that development of cognitive stages is structurally related to comprehension of speech act uncertainty.  相似文献

Approaches to Study of Distance Education Students   总被引:6,自引:0,他引:6  
The'Approaches to Studying'inventory of Ramsden and Entwistle (1981) was administered to groups of external and internal students at Capricornia Institute and the Tasmanian College of Advanced Education. Factor analysis revealed a similar factor structure for external students to that of the total sample. This finding, together with analysis of variance data, is taken as evidence that it is valid to use the inventory and the associated theories on learning styles with distance education students. Analysis of variance data showed differences in learning styles for older students. The implications of this finding for the design of distance education courses are discussed.  相似文献

Children from some demographic groups disproportionately receive special education (SE) services. Due to methodological shortcoming in existing work, it remains unclear whether this is due to real differences in academic needs or cultural selection/bias. Hence, in a community sample of 1250 Norwegian children, we examined the role of third grade SE services, academic test scores, behavioural problems, and teacher’s level of helplessness in mediating the effect of family socio-economic status (SES) and students’ gender on fifth-grade SE services. Results revealed no direct effects of either gender or SES on fifth-grade SE, but four mediated pathways were identified: (1) Boys had a greater likelihood of receiving fifth-grade SE services when (a) they previously received SE and (b) they experienced more ADHD symptoms, both in third grade. (2) Students from low-SES families were more likely to receive SE services in fifth grade when (a) they performed poorly in math in third grade and (b) their teacher reported greater feelings of helplessness when teaching these students. The findings are discussed with respect to the differential-needs hypothesis, mechanisms of cultural selection and the possibility of gendered selection for SE at younger ages.  相似文献

ABSTRACT

Mindfulness offers a pathway for preservice teachers to develop self-awareness, which is an essential part of personal and professional growth. However, supporting teacher self-awareness is rarely given much attention in teacher education programs. The authors studied the use of mindfulness meditation in an early childhood college course with early childhood preservice teachers. This article reports the main findings that emerged from the students’ journals regarding the mindfulness meditation. Reflecting on the findings, this article suggests that educators need to provide meaningful learning experiences and activities, which could help their students develop the personal qualities necessary to teach with high self-confidence.  相似文献
