This study examined the effects of students’ construction of computer-based educational games, using Scratch, on their mathematical equation-solving performance and their attitudes towards learning mathematics with the assistance of technology. A one-group, pretest-posttest quasi-experimental study design, was adopted. A total of 89 seventh grade students from three classes at a public school in Beijing, China, offering 9 years of compulsory education, participated in Scratch-based mathematical game-making activities. Data were collected via an equations-solving test, surveys, interviews and member checking, and pairwise t-tests were performed for data analysis. The results indicated significant improvements in students’ equation-solving performance and in their attitudes towards learning mathematics with the assistance of technology. 相似文献

ABSTRACTPhysical education emphasizes learning sports skills, which is why it is usually conducted in a face-to-face manner. Instructors focus on explaining rules and demonstrating moves, which the learners are required to repeat and imitate. Flipped classrooms have become a trend; thus, the present study investigated their influence on physical education. A mobile application for novice and advanced basketball players was developed and tested in a course teaching 3-on-3 basketball and various teaching methods were implemented to test for the effects of gender differences on learning outcome. The participants were students enrolled in the aforementioned course in a university in central Taiwan. 326 participants were included in the study, of whom 238 were male and 88 were female. The duration of the experiment was 5 weeks between May and June 2017, during which the correctness of moves, maneuverability, teamwork, sense of balance, and adaptability of the participants were evaluated and graded as their learning outcome. The research team observed the participants each week to gather empirical data for analysis. The results indicate that a mobile flipped classroom is the optimal teaching strategy, followed by projecting teaching; therefore, a mobile flipped classroom is the recommended approach to be integrated into physical education. 相似文献

This study investigated students’ modeling progress and strategies in a problem-solving simulation game through content analysis, and through supervised and unsupervised lag sequential analysis (LSA). Multiple data sources, including self-report models and activity logs, were collected from 25 senior high school students. The results of the content analysis found that the problem-solving simulation game helped most of the students to reflectively play with the science problem and build a workable model to solve it. By using the supervised LSA, it was found that the students who successful solved the game frequently linked the game contexts with the physics terminologies, while those who did not solve the problem simply relied on the intuitive knowledge provided in the reference materials. Furthermore, the unsupervised LSA identified four activity patterns that were not noticed in the supervised LSA: the fragmented, reference material centered, reference material aided modeling, and modeling centered patterns. Each pattern has certain associations with certain problem-solving outcomes. The results of this study also shed light on the use of different analytics techniques. While the supervised LSA is particularly helpful for depicting a contrast of activity patterns between two specific student groups, the unsupervised LSA is able to identify hidden significant patterns which were not clearly distinguished in the pre-defined student groups. Researchers may find these analytics techniques useful for analyzing students’ learning processes. 相似文献

This study investigates how social factors affect Taiwanese Internet users’ dual screening use and its impact on online and offline political participation. The Web survey recruits 961 dual screen users. Structural equation modeling results show that bridging social capital and perceived social presence are significantly associated with dual screening use. Dual screening is positively related to online and offline political participation. Dual screening use strongly influences offline political participation when mediated by online political participation. Moreover, alternative media trust is positively related to online political participation, whereas mainstream media trust shows a negative association. 相似文献

Currently, many of the electronic services are still new, and there may be a need for further fine-tuning and changes. Having separate electronic addresses for each service rather than having one centralized address will make it easier for NLM to identify and isolate questions or problems. The Appendix summarizes the commands and addresses mentioned in this article. 相似文献

The Effects of Outcome Uncertainties,Patriotism, and Asian Regionalism in the World Baseball Classic
This article investigates the effects of patriotism and Asian regionalism on game attendance and television viewers by using World Baseball Classic match data. The micro data of TV ratings provides comprehensive insights into the behavior of TV viewers. The results imply that attendance and TV viewers are affected by patriotism and Asian regionalism. Patriotism and regionalism have a significant positive effect on TV ratings. Although total points scored and game uncertainty are not significantly related to attendance and TV ratings in the game-level analysis, total points scored are significantly positively related to TV ratings in the inning-level analysis. Coefficients of inning-level uncertainty are partially negatively related to Videoland Sport's TV rating. The evidence weakly supports the hypothesis of game uncertainty. 相似文献

This paper reports the results of two semistructured focus group interviews with 17 retirees that explore the issues these retirees perceived as central to their learning in later life (LLL). Focus is especially placed on the factors leading to their learning interests after retirement. A total of six themes (past experience in adulthood and voluntary work, perception of learning, social support, living alone, self-efficacy, and openness) were identified to be related to learning interest in later life. This study has implications for future research and service planning of LLL in the Chinese population. 相似文献
