The purpose of this research was to propose a method to acquire the three-dimensional movement of a roller skiing athlete utilizing a global positioning system (GPS), an atmospheric pressure sensor (APS), and an inertial measurement unit (IMU) to distinguish between diagonal skiing and double poling techniques. In this study, we developed a lightweight wearable sensor that was composed of a GPS, APS, and IMU. For the data collection, two national level athletes roller skied a 1700 m long course where the maximum difference in elevation was 5.3 m. The planar positions of the athletes were based on the longitudinal and latitudinal data provided by the GPS, and the altitude was calculated by the International barometric formula and Laplace transform from the APS. The longitudinal and latitudinal data acquired through GPS had errors within 2 m range at each point. The altitude of Laplace transform from the APS showed errors of less than 1 m at each point. The range of motion of pelvis from the IMU was 34.0?±?3.8° for diagonal skiing, which is wider than the 21.2?±?6.9° for double poling. 相似文献

We investigated psychological dimensions of academic interest among undergraduate students (N = 325) using a global academic interest scale. The scale was administered together with measures of academic performance, educational aspiration, career planning, goal setting, life satisfaction, attitudes towards leisure, personality and value. Exploratory factor analyses revealed four dimensions of academic interest: passion for learning, confidence in the future, career aspiration and self-expression. All four dimensions were significantly related to career planning, goal setting and life satisfaction. On the other hand, specific pairings of significant relationships were found between different dimensions of academic interest and personality and value, suggesting that students with different personalities and different sets of values are likely to appreciate and respond to different aspects of academic interest. We conclude with implications for research on academic interest development across a more diverse range of age groups. 相似文献

This study explores what makes high achievement at a top university in order to gain insights into college learning. For this purpose, institution-wide in-depth interviews were conducted with the 45 highest achievers (GPA of 4.0/4.3 or higher) at a top Korean university, and the interview data were primarily analyzed qualitatively to investigate in-depth determinants. The results revealed that these highest achievers share the following specific cognitive, motivational, and self-regulation strategies: (1) they recorded all of the information provided in class; (2) used a motivational regulation strategy rather than motivation itself; and (3) were highly managerial in their cognition, emotions, physical condition, time management, and interpersonal relationships. These findings were verified by quantitative data obtained from online surveys of 1,111 students at the university. Critical implications and suggestions, such as institutional support, evaluation criteria, cultural differences, and other related issues, were discussed. 相似文献

To study deception, participants were randomly assigned the role of allocator or recipient in an ultimatum negotiation game. Allocators “earned” 7 dollars and divided the money between themselves and recipient and communicated the decision either face-to-face or through text chat. Recipients were unaware the amount the allocator had, and therefore, allocators could deceive. Most allocators used deception. We hypothesized that participants who self-identified as good liars would communicate more face-to-face than through text chat when deceiving, and this was supported for deceptive omission but not fabrications. Good liars were more likely to have their truths correctly detected than bad liars. 相似文献

This study investigated how Health Information National Trends Survey (HINTS) data from the U.S. National Cancer Institute (NCI) was cited in the scholarly literature. It addressed the following research questions: (1) What patterns of citations exist among authors of research articles using HINTS data? and (2) How is the citation format of HINTS data characterized? We collected scholarly articles that used HINTS data as primary or secondary data for analysis from Web of Science databases and HINTS publications on the NCI website. Among the resulting 250 articles, we identified citations to HINTS data themselves (data citations) and those to HINTS‐related documents (data‐related citations). Among the 250 articles, 156 articles (62.4%) cited HINTS data or HINTS‐related documents; only 29 articles (11.6%) cited HINTS data, while 127 (50.8%) cited HINTS‐related documents. Both data and data‐related citations increased over time. Data citation format varied, and 13 different compositions of citation elements were identified. Author, Title, and Location (URL) were common elements. The frequent use of URLs is undesirable due to URL instability. Furthermore, the data citations showed not only various compositions of citation elements but also ill‐defined element formats. Standardized citation formats are therefore needed. 相似文献

The current popularity of flipped learning may be attributed to its reported successes in bringing about enhanced learner engagement and positive learning outcomes. This study aims to improve our understanding of flipped learning (FL) outcomes by examining factors of learner engagement, academic capability, and epistemological beliefs. Data were collected and statistically analyzed from 231 undergraduate students enrolled in a general biology or general chemistry course at a Korean university implemented with the FL model. The results indicated that learners’ epistemological beliefs influenced neither pre-class nor in-class engagement, but that academic capability did affect both pre-class and in-class engagement. Only content/learning-related outcomes, not generic competencies or satisfaction, were affected by both academic capability and epistemological beliefs. Both pre-class and in-class engagement levels affected most types of FL outcomes except generic competencies, which were only affected by the extent of in-class engagement. Learners’ affective engagement was not influenced by epistemological beliefs, but directly and indirectly affected FL outcomes via behavioral and cognitive engagement. Theoretical and practical implications are discussed along with recommendations. 相似文献

This study proposes that the fundamental cultural differences between the East and the West lie in a holistic-analytic worldview, and this new perspective can explain the cultural differences better than collectivism-individualism. To test the claim, this study developed a measurement for holism and its derivative, cognitive relativity. Then, it examined the degree of holism, cognitive relativity, and independent and interdependent self-construals with Korean and American college students. Results showed that (a) Koreans had a stronger holistic worldview than Americans, (b) Koreans maintained a higher degree of cognitive relativity than Americans, (c) Koreans and Americans did not differ in either independent or interdependent self-construals, and (d) the impact of holism was still strong after controlling for the effects of self-construals. 相似文献

ABSTRACTThere appears to be something of an intellectual and philosophical gulf between education researchers who seek insights from statistical analyses of complex data-sets such as those provided by the OECD (PISA), and others who seek to develop rich, contextualised socio-historical understandings that can shed light upon why particular classroom practices operate and are sustained within a given milieu. This paper outlines these different perspectives, with particular reference to non-cognitive factors. Detailed analysis of the roots of high academic achievement, and associated challenges to student wellbeing, in many East Asian countries, is provided. The important influence of broad political and societal factors is highlighted by reference to cross-cultural differences across a large number of countries. The paper concludes by stating that while data from large datasets can assist in gaining greater understanding of cross-cultural differences, to be meaningful, such analyses should be incorporated within complex ecosystemic accounts. 相似文献

AbstractThis study examined learning strategy use in mathematics among East Asian students in East Asian educational systems. By employing latent class analysis on the Programme for International Student Assessment (PISA) 2012 data, we found four classes of learning strategy types, namely memorization with metacognitive strategies (17.49%), metacognitive strategies with memorization (50.70%), elaboration only (10.33%), and metacognitive strategies with elaboration (16.47%). The results showed that the majority of the students in all seven East Asian educational systems belonged to the ‘metacognitive strategies with memorization’ class, and most students adopted more than one type of learning strategy when learning mathematics. Additionally, students who reported the use of metacognitive strategies along with either memorization or elaboration showed higher mathematics achievement. We conclude that the cognitive processes employed by students of East Asian backgrounds are more complex and nuanced than the previous perception that they relied heavily on memorization. 相似文献
