This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores. 相似文献

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes
towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the
35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the
30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and
QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry
laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest
magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal
behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student
interactions for gifted students are provided. 相似文献

Village Elders’ and Secondary School Students’ Explanations of Natural Phenomena in Papua New Guinea
Soikava?Pauka David?F.?TreagustEmail author Bruce?Waldrip 《International Journal of Science and Mathematics Education》2005,3(2):213-238
This research investigated the sources of explanations and understanding of natural phenomena in terms of the students’ cultural and school science experiences. The first phase involved interviews with eight village elders that probed their explanations and understanding of natural phenomena. The second phase involved the design, development and administration of two questionnaires on natural phenomena to 179 students in a rural boarding high school in Papua New Guinea (PNG). Most village elders gave explanations of many of the phenomena in terms of spirits, spells, magic, religion, and personal experiences. Most school-aged students choose scientific explanations of natural phenomena in terms of what they had learned in school or from personal experiences. However, many choose explanations of the same phenomena about spirits, spells and magic that came from the village, family or home. The study revealed that students’ ideas about natural phenomena are strongly governed and controlled by their school science knowledge in the school setting. It is likely that their own traditional knowledge cannot be identified in a school setting but that questionnaires in the students’ local language be given to students in their villages (as opposed to school). In addition, so as not to diminish the value of this traditional knowledge, science education programs are needed that are able to consider and harmonise traditional knowledge with school science. 相似文献

AbstractTo foster lifelong learning skills, we need new didactic approaches with aligned assessment methods. Therefore, we investigated whether the outcomes of a project assignment show a different relation to learning strategies than a longitudinal knowledge-based assessment. We studied learning strategies of first year students of medicine and biomedical sciences (n?=?248) and performed hierarchical regression analyses for the learning strategies and grades of the longitudinal knowledge-based test and project assignment. Scores of students, measured with the Motivated Strategies for Learning Questionnaire (Likert scale 1–7), were relatively low for critical thinking (3.53), compared to rehearsal (4.40), elaboration (4.82), organisation (4.69) and metacognitive self-regulation (4.33). Knowledge based tests showed a significant relation to elaboration (p?<?0.01). For the project-based assessment, we did not find a significant relation to any learning strategy (p?=?0.074). Explained variance of the grades was low for all learning strategies (R2 < 0.043). Different types of assessment did not discriminate between students with high or low scores on learning strategies associated with lifelong learning. An explanation is that the curriculum is not aligned with assessment, or students do not benefit in terms of grades. We conclude that, if assessment is to drive lifelong learning skills, this is not self-evident. 相似文献

In this paper, we investigate the effects of a community- and school-based service learning experience (SLE) on pre-service physical education teachers’ Indigenous knowledge, cultural competency and pedagogy. Informed by the theoretical tenets of Indigenous research methodologies, experiential learning and critical reflection, we examine 55 final-year pre-service physical education teachers’ (age: 21.9 [8.3]; 10.7% low SES; 68% females) cultural learning and competency in a core unit of study with a six-week SLE. Measures of their experiences included reflective journals, multicultural teaching competency scales and focus group interviews. Findings support the design of the SLE, with statistically significant changes in pre-service teachers’ perceptions of their cultural competency (p < 0.001). Pre-service teachers were able to challenge their assumptions about Indigenous students, plan and implement student-centred and culturally relevant pedagogies. Attention is drawn to the design of this SLE and demonstrates the importance of using Indigenous community members and teachers as mentors, which has not been explored in previous SLE studies. 相似文献

This study provides a Canada-wide snapshot of the self-efficacy and beliefs of 1490 preservice teachers in relation to inclusive teaching using the Teacher Efficacy for Inclusive Practice and the Beliefs about Learning and Teaching Questionnaire. At the time of data collection, these preservice teachers were in the final stages of their teacher education programmes. Based on the results of surveys in 11 Faculties of Education, men have higher self-efficacy than women for managing behaviour in the classroom, elementary preservice teachers have higher self-efficacy in collaboration than those teaching in secondary schools, those enrolled in the 1-year post-degree programme show lower self-efficacy than those enrolled in programmes of other durations, and those who have experience with people with special education needs show higher self-efficacy than those who do not. Differences illustrated that women were more inclusive than men, 1-year post-degree preservice teachers were less inclusive than others, and those who have experience with people with special education needs are more inclusive than those who do not. Recommendations for teacher education and limitations surrounding the practical significance of the findings are discussed. 相似文献
