Service learning provides pre-service educators with a context for having hands-on field experience and also assists in understanding the theory and practice. This study discusses 7 undergraduates' implementations of learning stations as their service learning with 28 elementary school students. Through thematic data analysis of interviews, observation field notes, activity designs, and discussion posts, this study presented the following major findings. First, elementary school students, seven undergraduates, and a cooperative elementary school English teacher held positive attitudes towards the implementation of learning stations, because these developed children's cooperation and word recognition skills. Second, undergraduates and cooperative teachers gained professionalism through reflection and cooperation, in terms of activity designs, classroom management, and interpersonal skills development with kids and adults. Five suggestions are provided in order to effectively implement undergraduates' activity designs for learning stations as their service learning among elementary school students. 相似文献

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition. 相似文献

The Common Core State Standards Initiative has placed an increased focus on mathematics and English language arts. A relationship between physical activity and academic achievement is evident, but research on integration of academic subjects with physical education is still unclear. This literature review examined databases for the years 2004–2013, focusing on physical education or physical activity and core academic subjects for school-aged youth. 23 studies were found that focused on integration and physical education that met the inclusion criteria. These were from 16 different publication outlets, ranging in research methods, country, and population. This review provides information on the status of integration and physical education. Since classroom teachers are increasingly being encouraged to incorporate core subjects with physical activity into their classes, it would be appropriate for physical educators to understand the desired outcomes of integration of core subjects before attempting its implementation. 相似文献

As the advance of learning technologies and analytics tools continues, learning management systems (LMSs) have been required to fulfil the growing expectations for smart learning. However, the reality regarding the level of technology integration in higher education differs considerably from such expectations or the speed of advances in educational technologies. This research aimed to evaluate the current activation levels and usage patterns of a LMS. A large data-set was analysed, which included the online activity information from 7940 courses. Through data pre-processing, general indicators reflecting login frequencies of the virtual campus and activity-based indicators presenting the activation patterns of diverse functions provided by Moodle were derived. Activity theory was applied to interpret the results of analysis, since it has been recognised as a powerful framework to understand phenomena encompassing interactive systems. Further, time-series investigation over three consecutive semesters allowed observation of historical changes. The results revealed considerably low use of the virtual campus with only slight changes, as well as significantly different activity patterns across course attributes and colleges. Contradictions among components in the activity system are discussed, along with the implications for improving teaching and learning with LMS in higher education. 相似文献

This formative intervention documents the emergence of a hybrid activity aiming at student engagement and academic achievement. In this context-bound study, early stages of this activity consisted in establishing PénArt meant to enable high school students with difficulties to start up their own business at school. It involved reaching agreements between a high school and a youth centre so that high school students engage in the production and selling of their branded t-shirt. At the frontiers of their respective activity system, students, youth workers, special education teachers and members of the school board took actions to cross boundaries and redefine their interrelations. Cultural historical activity theory was fruitful to document the development of a new object-oriented activity. Tensions and contradictions revelaled to be the key moments in the emergence of the hybrid activity. Expansive learning led us to understand that, in a conflicting situation, a collective’s agentive actions create an expansive form of learning and leads to a successful entrepreneurship experience. Change laboratory capacity to foster change for cooperative education in Quebec was successful. The students enrolled in a regional entrepreneurship contest and won it. That was a significant event for students with low self-esteem linked with their performance at school. 相似文献

This response draws from the literature on adaptive learning, traditional ecological knowledge, and social–ecological systems
to show that Brad’s choice is not a simple decision between traditional ecological knowledge and authentic science. This perspective
recognizes knowledge systems as dynamic, cultural and historical activities characterized by diverse worldviews and ways of
constructing and legitimizing knowledge. Brad’s decision is seen as an example of adaptive learning, identity development
and personal/collective agency oriented to increasing tribal influence in resource management decisions and policies. I will
conclude that science literacy for all is not served by a transcendent, universal, Western modern view of science.
