Because of a shortage of physical exercise, concerns about adolescents have recently been raised in Taiwan. In educational environments where student exercise has been limited by scheduling constraints and the lack of physical exercise has become a vital problem, “learning while exercising” may be part of a possible solution. This study developed the Ecosystems Augmented Reality Learning System (EARLS) and also made a comparison of EARLS, existing keyboard/mouse-based computer assisted instruction (KMCAI) approaches, and traditional face-to-face teaching methods, in terms of learning achievement and learning attitude. In this study, 1211 subjects were surveyed and divided into 5 groups. Students from the first three groups used EARLS but were exposed to different sections of the system. In terms of learning achievement, learning while exercising groups do not learn less well than the KMCAI or traditional groups. However, they earn extra exercise without diminishing the quality of learning achievement. With regard to the attitude subscales “Usefulness of learning Ecosystems” and “Anxiety in learning Ecosystems”, the students in the traditional-teaching group had the significantly lowest scores for both while the students involved in EARLS had the highest ratings on “Usefulness of learning Ecosystems” and the students within KMCAI rated the highest anxiety in learning ecosystems. 相似文献

The aim of this study was to analyze the correlation among teachers’ perceived acceptance of technological innovation, organisations’ innovation climate, and innovative teaching using information and communication technology (ICT) in Taiwan. The participants (N?=?482) responded to a questionnaire using a five-point Likert scale for each factor, and their responses were analyzed using structural equation modeling (SEM). This research found that an organisation’s innovation climate is significantly and positively related with innovative teaching using ICT, and that the acceptance of technological innovation is significantly and positively related with innovative teaching using ICT, as supported by the organisation’s innovation climate. The influence pattern and empirical data of the acceptance of technological innovation and the organisation’s innovation climate on innovative teaching with ICT exhibited a good fit. The implications of such findings were discussed. 相似文献

Sensitivity Analysis of the No-Omitted Confounder Assumption in Latent Growth Curve Mediation Models

Latent growth curve mediation models are increasingly used to assess mechanisms of behavior change. For latent growth mediation model, like any another mediation model, even with random treatment assignment, a critical but untestable assumption for valid and unbiased estimates of the indirect effects is that there should be no omitted variable that confounds indirect effects. One way to address this untestable assumption is to conduct sensitivity analysis to assess whether the inference about an indirect effect would change under varying degrees of confounding bias. We developed a sensitivity analysis technique for a latent growth curve mediation model. We compute the biasing effect of confounding on point and confidence interval estimates of the indirect effects in a structural equation modeling framework. We illustrate sensitivity plots to visualize the effects of confounding on each indirect effect and present an empirical example to illustrate the application of the sensitivity analysis. 相似文献

Technical and vocational education emphasizes the development and training of hand motor skills. However, some problems exist in the current career and aptitude tests in that they do not truly measure the hand motor skills. This study used the Nintendo Wii Remote Controller as the testing device in developing a set of computerized testing tools to measure the hand motor skills. Through literature analyses, expert reviews, and analysis of the experimental data, it has been confirmed that these computerized testing tools are stable and effective; in addition, the test results were not influenced by gender or prior experiences with using sensor devices. Moreover, the computerized test was capable of diagnosing and measuring the hand motor skills of participants in a safe, low-cost, virtual testing environment. In focusing on the learning experiences from vocational school practice classes, this study provides a reference for decision-making regarding further education and career development. 相似文献

Exercise systematically improves physical and psychological performances on a wide range of measures, but the links between them are rarely examined for the high homogeneous group of institutionalized veterans. This study aims to investigate the exercise intervention effects on both depressive symptoms and body-balance. Samples were divided into experimental-group (N = 11, mean age = 80.67) and the control-group (N = 10, mean-age = 82.54). The experimental-group received 10 sessions of exercise intervention, including aerobic cycling and leg stretching (muscular endurance), while the control-group attended lecture sessions on health education. Depressive symptoms: the findings show the intervention has no significant intragroup effect on either the experimental-group or the control-group; but a high and median effect-size (EF with Cohen’s d) was found for both the experimental and the control group (d = .916 and .504, respectively). The intergroup difference was small (p = .748; d = .136). Balance-ability: the findings show no statistically significant intragroup effect on the 5-stage balance test within the experimental-group, and the EF is low. In the control-group, health education intervention had no improvement on the 5-stage balance test, but there was a moderate decrease in balance Stage-4 (d = ?.626). Additionally, the strong intergroup effect (d = 1.621, p = .003) indicated that the experimental-group is superior to the control-group at Stage-4, and there was a moderate effect at stage-3 and stage-5 (d = .567 and .495, respectively). The current study shows that exercise can help adults older than 80 to ameliorate depressive symptoms and enhance body balance ability, and the findings deserve more attention. 相似文献

Gender bias exists in our language environment. We investigated personal name usage in two large corpora of language written for and by U.K. children aged 5–13. Study 1 found an overrepresentation of male names in children’s books, largely attributable to male authors. In stories written by over 100,000 children, Study 2 found an overall male bias that interacted with age. Younger children wrote more about their own gender. With age, girls became more balanced yet boys continued to show a strong male bias. Our findings demonstrate a male-centered bias in both children’s books and their own writing. We consider the power of written language to both shape and be shaped by cultural stereotypes via systematic biases in gender associations. 相似文献

Online programming discussion forums have grown increasingly and formed sizable repositories of problem-solving solutions. In this paper, we investigate programming learners’ information seeking behaviors in online discussion forums, and provide visual navigational support to facilitate information seeking. We design engines to collect students’ information seeking behaviors, and model these behaviors with sequence pattern mining techniques. The results show that programming learners indeed seek for information from discussion forums by actively search and read progressively according to course schedule topics. Advanced students consistently perform query refinements, examine search results and commit to read, however, novices do not. Finally, according to the lessons learned, we propose, design and evaluate Personalized Information Seeking Assistant system to help query refinement by summarizing the search results and to provide social-based browsing history. Findings suggest that paying attention to the query history may lead to further reading events, which subsequently resulting in potential learning activities. 相似文献

In the study described in this article a questionnaire was employed that can be used to assess students' and teachers' perceptions of science teachers' interpersonal communication behaviors in their classroom learning environments. The Teacher Communication Behavior Questionnaire (TCBQ) has five scales: Challenging, Encouragement and Praise, Non‐Verbal Support, Understanding and Friendly, and Controlling. The TCBQ was used with a large sample of secondary science students in Taiwan, which provided additional validation data for the TCBQ for use in Taiwan and cross‐validation data for its use in English‐speaking countries. Girls perceived their teachers as more understanding and friendly than did boys, and teachers in biological science classrooms exhibited more favorable behavior toward their students than did those in physical science classrooms. Differences were also noted between the perceptions of the students and their teachers. Positive relationships were found between students' perceptions of their teachers' communication behaviors and their attitudes toward science. Students' cognitive achievement scores were higher when students perceived their teacher as using more challenging questions, as giving more nonverbal support, and as being more understanding and friendly. The development of both teacher and student versions of the TCBQ enhances the possibility of the use of the instrument by teachers. © 2002 John Wiley & Sons, Inc. J Res Sci Teach 39: 63–78, 2002 相似文献

ABSTRACTThe flipped classroom pedagogy has been widely used recently. Despite many researches have paid attention with the learning outcome of flipped classroom, there has been limited attention in regard to investigate the relationship between learning behavior and learning outcomes in a flipped classroom. In this paper, we proposed to investigate the influence of online learning behaviors on short-term and long-term learning outcomes in a flipped classroom. This study used Calculus and grade point average (GPA) scores to represent short-term and long-term learning outcomes, respectively. Multiple linear regression indicated that students’ online learning behavior does not have a significant effect on short-term learning outcomes, but has a significant effect on long-term learning outcomes. For applying multiple correspondence analysis, students were divided into groups according to five grade levels based on their scores. According to GPA grade level, students’ online learning behaviors had a significant effect on long-term learning outcomes for the five groups (GPAa, GPAb, GPAc, GPAd, GPAe). According to their Calculus grade level, students’ online learning behaviors had a significant effect on short-term learning outcomes for three groups (CALa, CALd, and CALe), but two groups (CALb and CALc) did not demonstrate this trend. For exploring the effects of online learning behaviors on future learning outcomes, GPA can be considered representative because the GPA was calculated for the entire academic year 2015. Students in the CALa group exhibited the highest frequency of online learning behaviors and obtained the highest GPA grade levels (GPAa and GPAb). For the CALb, CALc, CALd, and CALe groups, students with a higher frequency of online learning behaviors obtained a higher GPA grade level. These results indicate that students’ online learning behaviors have a positive effect on future learning outcomes. 相似文献
