This article describes how a detailed notebook analysis was used to assess and compare the opportunity to learn of a sample of grade 6 students from 126 classes in South East Botswana and North West Province, South Africa. Students’ mathematics notebooks provided the main data source for estimating how much time is spent on the subject during the 6th grade year, and what mathematics is covered relative to what the study’s student test asked the sample of students. The notebook analysis shows that in sample classes in both countries, most teachers were giving an average number of mathematics lessons that was considerably lower than the number officially programmed under each country’s ministry guidelines. It also reveals that, on average, teachers in both samples of classes covered just over a third of the possible topics related to the test items between the pre-test and post-test. Nevertheless, substantial differences in students’ opportunities to learn in the two countries are evident.  相似文献

This work investigates the effectiveness of simulated robots as tools to support the learning of programming. After the completion of a systematic review and exploratory research, a multi-case case study was undertaken. A simulator, named Kebot, was developed and used to run four 10-hour programming workshops. Twenty-three student participants (aged 16–18) in addition to 23 pre-service, and 3 in-service, teachers took part. The effectiveness of this intervention was determined by considering opinions, attitudes, and motivation as well as by analysing students’ programming performance. Pre- and post-questionnaires, in- and post-workshop exercises, and interviews were used. Participants enjoyed learning using the simulator and believed the approach to be valuable and engaging. The performance of students indicates that the simulator aids learning as most completed tasks to a satisfactory standard. Evidence suggests robot simulators can offer an effective means of introducing programming. Recommendations to support the development of other simulators are provided.  相似文献

This article presents a systematic scoping review of the literature focusing on interactions between classroom dialogue and digital technology. The first review of its type in this area, it both maps extant research and, through a process of thematic synthesis, investigates the role of technology in supporting classroom dialogue. In total, 72 studies (published 2000–2016) are analysed to establish the characteristics of existing evidence and to identify themes. The central intention is to enable researchers and others to access an extensive base of studies, thematically analysed, when developing insights and interpretations in a rapidly changing field of study. The discussion illustrates the interconnectedness of key themes, placing the studies in a methodological and theoretical context and examining challenges for the future.  相似文献

This study investigated how Health Information National Trends Survey (HINTS) data from the U.S. National Cancer Institute (NCI) was cited in the scholarly literature. It addressed the following research questions: (1) What patterns of citations exist among authors of research articles using HINTS data? and (2) How is the citation format of HINTS data characterized? We collected scholarly articles that used HINTS data as primary or secondary data for analysis from Web of Science databases and HINTS publications on the NCI website. Among the resulting 250 articles, we identified citations to HINTS data themselves (data citations) and those to HINTS‐related documents (data‐related citations). Among the 250 articles, 156 articles (62.4%) cited HINTS data or HINTS‐related documents; only 29 articles (11.6%) cited HINTS data, while 127 (50.8%) cited HINTS‐related documents. Both data and data‐related citations increased over time. Data citation format varied, and 13 different compositions of citation elements were identified. Author, Title, and Location (URL) were common elements. The frequent use of URLs is undesirable due to URL instability. Furthermore, the data citations showed not only various compositions of citation elements but also ill‐defined element formats. Standardized citation formats are therefore needed.  相似文献

Most U.S. higher education institutions have implemented initiatives to increase campus diversity. The intended outcome is to reduce educational inequities among underrepresented populations. Such initiatives have come under fire, however, for serving as a superficial solution to educational inequities. Here I propose the application of an action-knowledge conceptual framework to explore why money and policy change are not enough to create campus environments where multi-culturalism enhances student learning. Argyris' (1985) notion of double-loop learning recognizes the necessity for actionable knowledge to be instilled in practitioners in order for diversity initiatives to truly achieve desired outcomes and have lasting effects.  相似文献

A qualitative study of faculty members participating in a campus-wide problem-based learning initiative examined the process of transforming faculty pedagogical content knowledge. Researchers found that faculty existing knowledge and the institutional intervention influenced new knowledge of faculty roles, student roles, disciplinary structures, and pedagogy. Communicating new knowledge solidified the transformation.  相似文献
