In this study, researchers designed and implemented a 1-year professional development (PD) program that focused on supporting teachers in evaluating and selecting digital learning contents. Participants in this investigation included 109 teachers who consented to the study amongst a total of 171 teachers from five school districts across central Ohio. In addition to their participation in the PD program, they completed surveys, interviews, and self-reflections in this mixed-method study. The results revealed that teachers’ perceived TPACK increased over time throughout the PD program, suggesting that training teachers to evaluate digital contents can be an effective PD model to improve teachers’ capacity in learning technology integration. The PD program was especially effective for teachers with less prior experience in technology integration or related training. Mathematics teachers, in comparison to teachers from other disciplines, began with low TPACK; however, these initial differences gradually diminished over the course of the PD program. In terms of their motivation in digital content evaluation, teachers’ expectancy for success increased significantly while their task values remained medium high. The qualitative analyses provided additional insights and revealed design suggestions for success in future PDs. 相似文献

ABSTRACT Criticisms have been levelled at academics at a time when funding of universities is increasingly tied to private and corporate purposes and when academics are held accountable through a hierarchy of functions. Claims are also made that academics work within narrow specializations and are removed from real-world experience and problems. Boyer’s model of scholarship offers four categories of scholarship that remain relevant to understanding and guiding the work of academics, including how they engage with communities. To explore the nature of academics’ work, we draw on data provided by a group of academics who participated in a research project using both sociological elicitation and visual arts-based research methodologies. The participants were asked to explore what various aspects of current academic work mean for them by providing an image and text, akin to creating a postcard. In this article, we focus on responses they provided to the prompt ‘Community engagement is?…?’ The postcards show how community engagement can be interpreted in diverse ways and that, along with teaching and research, community engagement are all integrated, mutually reinforcing drivers and outcomes of academic work. 相似文献

Peer acceptance during early childhood is related to children's academic achievement, adjustment in school, and even psychological well-being in adulthood. Children who experience low peer acceptance exhibit socially inappropriate behavior patterns, which are associated with irrelevant patterns of information processing. Therefore, as a way of helping children with low peer acceptance, a cognitive-social learning model of social skills training has been used because the model focuses on cognitive changes as well as behavioral changes. Three parts of the social skills training—enhancing skill concepts, promoting skill performance, and fostering skill maintenance/generalization—are discussed. In order to be successful, a trainer should understand the training model as well as behavioral patterns of children with low peer acceptance to provide theory-based and individualized feedback to each participant. 相似文献

This study draws on institutional theory to examine teachers’ and principals’ perceptions of new teacher evaluation policies, factors that influence such perceptions and how such perceptions shape the implementation of the policies in Seoul (Korea) and Michigan (USA). The study featured in-depth interviews of 11 elementary school teachers and 4 principals and analysis of policy documents in both countries. While Korean teachers strongly disagreed with the new teacher evaluation policy in Seoul and implemented it in ways that were not intended by policy makers, the Michigan teachers varied in their perceptions and implementation of the policies. The teachers’ perceptions of the new policies seemed to be influenced by the designs of the policies, their backgrounds and definitions of ‘effective teachers’ and principal leadership. The association between teachers’ perceptions and their implementation of the new policies was quite strong. 相似文献

We examined how raters and tasks influence measurement error in writing evaluation and how many raters and tasks are needed to reach a desirable level of .90 and .80 reliabilities for children in Grades 3 and 4. A total of 211 children (102 boys) were administered three tasks in narrative and expository genres, respectively, and their written compositions were evaluated in widely used evaluation methods for developing writers: holistic scoring, productivity, and curriculum-based writing scores. Results showed that 54 and 52% of variance in narrative and expository compositions were attributable to true individual differences in writing. Students’ scores varied largely by tasks (30.44 and 28.61% of variance), but not by raters. To reach the reliability of .90, multiple tasks and raters were needed, and for the reliability of .80, a single rater and multiple tasks were needed. These findings offer important implications about reliably evaluating children’s writing skills, given that writing is typically evaluated by a single task and a single rater in classrooms and even in some state accountability systems. 相似文献

The use of two‐dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low‐quality and high‐quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low‐quality or high‐quality images, and then completed a comprehension test using either 2D images or three‐dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high‐quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high‐quality vs. low‐quality for hand anatomy P = 0.018; high‐quality vs. low‐quality for eye anatomy P = 0.247). Also, the benefit of high‐quality images on hand anatomy learning was restricted to performance on short‐answer (SA) questions immediately after learning (high‐quality vs. low‐quality on SA questions P = 0.018), but did not apply to performance on multiple‐choice (MC) questions (high‐quality vs. low‐quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

In recent years, most studies on flipped classrooms or flipped learning have focused on learners’ motivation, academic achievement and teachers’ and students’ perceptions of the flipped classroom. Little research has involved interactions in the flipped classroom. This study aims to show that in-class collaborative learning in the flipped classroom can not only be conceived as a collective activity consisting of discrete actions, but also as a systematic activity. From the activity-theoretical perspective, contradictions were found between components of an activity such as subject, tools, rules, community, division of labor, object and outcome. This study conducted a pre-experiment, selecting one lesson of the seventh-grade Information Technology Course as the learning content, conducted in a flipped classroom. Three triads with different compositions were specifically observed by recording their interactions. More second-level contradictions existed between subject and tools, and division of labor within the low-level triad than within the other two triads, and more first-level contradictions also occurred within the low-level triad than within the other two triads. Most second-level contradictions within the high-level triad were resolved by self-regulation of cognition. Instead, most second-level contradictions within the mixed-level triad were overcome by co-regulation or shared regulation of cognition. This study sheds light on how to effectively design and implement flipped learning, and provides a new approach for analyzing interactions in the classroom. 相似文献

This study examined the role of instruction for spelling performance and spelling consciousness in the Dutch language. Spelling consciousness is the ability to reflect on one's spelling and correct errors. A sample of 115 third-grade spellers was assigned to a strategy-instruction, strategic-monitoring, self-monitoring, or control condition representing different types of metacognitive aspects. The results showed that students in all three training conditions made more progress in both spelling performance and spelling consciousness than students in the control condition. With respect to spelling consciousness, only students in the strategy-instruction condition made significant improvement between pretest and posttest. Students made more progress in spelling performance on regular words than on loan words. Students in all four conditions became more accurate at assessing which words they could spell correctly. Students in the control condition more frequently overestimated their spelling ability. 相似文献

INTRODUCTION A 3D solid model is used in various processes such as design, engineering evaluation, drafting, manufacturing, and so on. It is a time-consuming and skill-required job to create a complicated 3D solid model. Most commercial CAD tools support func- tions to generate engineering drawings from solid models automatically. However, adjusting layouts, dimensioning, and inserting annotations are required and they are tedious and time-consuming work. Most current CAD/CAM/CAE so… 相似文献
