This article uses a self-study research methodology to explore teaching an online course for mathematics specialists. The course included weekly videoconferencing sessions and focused on supporting their development as mathematics coaches working with K-8 teachers to enhance mathematics teaching and learning. The central question for the self-study was about the design of the course and the characteristics of the learning environment that resulted from the design. The study included journal reflections and survey data. Three themes emerged in the analysis of the instructional decision making for the course: student autonomy and engagement, authenticity and practicality, and fostering community.  相似文献

This study investigates three teachers’ uses of a dynamic geometry program (The Geometer’s Sketchpad) in their high school geometry classes over a 2-year period. The researchers examine teachers’ actions and questions during pivotal teaching moments to characterize mathematics instruction that utilizes technology. Findings support an association between teacher–tool relationships, predominant teacher actions, and questioning.  相似文献

Two experiments explored the effects of reading digital storybooks on tablet computers with 25 preschoolers, aged 4–5. In the first experiment, the students’ word recognition scores were found to increase significantly more when students explored a digital storybook and employed the read-aloud function than when they were read to from a comparable print book. Their comprehension scores did not change significantly in the two conditions. In Experiment 2, the same students explored digital storybooks with more animation embedded in them. The students listened to the read aloud function on the tablet computer and explored digital storybooks in both conditions, but in one condition a teacher guided the talk about the story. Contrary to expectations, the students’ word recognition and story comprehension scores were higher in the independent condition than in the guided condition. One explanation for the higher word recognition scores when students were reading with the tablet computer is the effect of multimedia, like hotspots and/or text tracking. Although digital storybooks are not a substitute for adult interaction, these preschoolers learned surprisingly well on their own. The importance of digital storybook design, as well as what elements to look for in an e-book to encourage literacy learning are discussed.  相似文献

Curriculum development is particularly challenging in computing-related disciplines as the computing industry changes more quickly than most. As information technology degrees have become relatively pervasive, some institutions that offer information systems degrees have recognized a need to develop specialist studies in information systems. This detailed case study shows the forces related to a successful implementation of new Health Informatics degrees. The case describes both an unsuccessful and then a successful attempt at essentially the same curriculum development. Although the case includes some local political factors, these represent typical considerations that a curriculum developer is likely to encounter.  相似文献

Dyslexia is one of the most common learning disabilities. It is described as a disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence, and sociocultural opportunity. It affects relatively about 7–10 % of the population across most languages and cultures. In this study, we explore the potential benefits offered by the use of Information and Communication Technology (ICT) to support dyslexic students by considering their preferred learning styles. In the current paper we administered the VAK and Honey & Mumford questionnaires to 28 Arabic students with ages between 8 and 10 years old. 8 students from dyslexic group and 20 students from control group were selected to assess and compare their preferred learning style. The implemented system focuses on dyslexia in Arabic language, especially in Arabic countries such as Morocco. Based on the results of the analysis of learning styles differences, we introduced an adaptive mobile learning to support and promote learning for dyslexic students. The aim of the study is to consider the relationship between dyslexia and learning style and to suggest a different learning way. Preliminary results show that the ICT has a valuable role in providing opportunities for learners with dyslexia to participate more fully in education.  相似文献

Although the flipped class has been hotly discussed, the clicker-aided flipped EFL class (CFEC) still remains a mystery for most scholars. This study aims to determine the correlations between the initial EFL proficiency and other variables of the clicker-aided EFL flipped class. The sample was made up of randomly selected 79 participants (Female =38; male =41), who received the clicker-aided EFL flipped class for one academic semester. It is found that there is a significantly positive relationship between the initial and the final EFL proficiency, motivation levels and cultural awareness in CFEC, whereas there is a negative relationship between initial EFL proficiency and cognitive loads in CFEC. The initial EFL proficiency is therefore an essential factor to influence the effectiveness of the flipped class. Future studies may consider this when exploring the educational technology aided flipped class.  相似文献

The study builds on a newly modified Technology Acceptance Model (TAM) to substantiate the motivation and operation of teachers’ utilization of online learning resources. A ‘Comprehensiveness’ construct is proposed in the modified TAM to reflect the breadth and depth of rich online knowledge. This new construct serves as the mediator between ‘Usefulness’ and ‘Behavioral Intention’ in the new TAM structure. In addition, the ‘Ease of Use’ factor in conventional TAM is proposed to moderate the mediation in the modified TAM. Survey data are collected from 301 teachers undertaking certified training in Macau and Structural Equation Model (SEM) technique is used to assess the model. Moderated mediation is evaluated using both multi-group bootstrapping method and moderated path analysis method. Both methods verify the presence of moderated mediation with partial mediation in high Ease of Use values and full mediation in low Ease of Use values. Theoretical implication of the current study extends the coverage of TAM applications and academic implication suggests the strengthening in teachers’ professional development and government sponsorship in building repositories of online resources.  相似文献

One prominent problem of conducting observational assessments of teaching quality is the possibility of reactivity effects. To date, the issue of reactivity has received limited empirical attention. The present study, therefore, investigated reactivity in 447 students from 24 classes as well as their 12 teachers. We compared reactivity during lessons that were video-recorded with those that were not: according to t?test analyses of teacher ratings and MIMIC analyses of student ratings, no significant differences emerged in teaching quality or teaching practices. Significant differences were found in teacher and student emotions, as well as in student cognition and behavior. Supplementary eye-tracking analyses indicated reactivity depleted after 1?min 20?s. The results are discussed with respect to their relevance for future video studies on classroom instruction.  相似文献

Research has established that adolescents both befriend peers based on their academic achievement and adjust their own achievement to that of their friends’ over time. However, these processes may be different for ethnic minority students, because some of them may adhere to an oppositional culture that rejects striving for academic success. We examine respective differences between self-identified ethnic minority and majority students using longitudinal social network analysis (stochastic actor-oriented models) in a sample of 1175 students (aged 13) from 12 grade-level networks in Germany secondary schools. Among the students, we find that academically successful students in particular prefer friends with high grades, but that students with poor grades exert more social influence on their friends to adjust their performance. Moreover, while minority students are indeed less inclined to select friends with higher grades, both ethnic majority and minority youth prefer friends with similar academic achievement and are similarly influenced by their friends’ achievement. However, social influence is stronger from same-ethnic than from inter-ethnic friends. In sum, there is mixed evidence for an oppositional culture among ethnic minority students in our sample.  相似文献

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research.  相似文献
