Gestural motions of the hands and fingers are powerful tools for expressing meanings and concepts, and the nervous system has the capacity to retain multiple long-term motor memories, especially including movements of the hands. We developed many sets of successive movements of both hands, referred to as "digit anatomy," and made students practice the movements which express (1) the aortic arch, subclavian, and thoracoacromial arteries and their branches, (2) the celiac trunk, superior mesenteric artery and their branches, and formation of the portal vein, (3) the heart and the coronary arteries, and (4) the brachial, lumbar, and sacral plexuses. A feedback survey showed that digit anatomy was helpful for the students not only in memorizing anatomical structures but also in understanding their functions. Out of 40 students, 34 of them who learned anatomy with the help of digit anatomy were "very satisfied" or "generally satisfied" with this new teaching method. Digit anatomy that was used to express the aortic arch, subclavian, and thoracoacromial arteries and their branches was more helpful than those representing other structures. Although the movements of digit anatomy are expected to be remembered longer than the exact meaning of each movement, invoking the motor memory of the movement may help to make relearning of the same information easier and faster in the future. 相似文献

The reaction video is an understudied area in YouTube and other online scholarship. Despite its limited scholarly attention, it is an influential site of meaning making, particularly for global youth cultures. Understanding polyculturalism as the suturing of self into multiple lineages, this project argues that Black American fans self-represent their K-pop fan interests as being salient to their racial identities. The videos construct identities that are not confined to the Black–White paradigm. Instead, YouTubers engage in fan practices of production, represent conformity to values within the fan community, articulate racially specific fan participation, and express concern for racially specific marginalizing discourses. Thus, the YouTube response video becomes a complicated site with multiple negotiations that reveal the self-production of polycultural identities. 相似文献

Adolescents’ dyadic relationships are likely influenced by the cultural context within which they exist. This study applied a person-oriented approach to examine how perceived support and negativity were manifested across youths’ relationships with mothers, fathers, and best friends, simultaneously, and how distinct relationship profiles were linked to adaptive and maladaptive functioning (aggression, anxious-withdrawal, prosociality) within and across cultures. Participants resided in metropolitan areas of South Korea, the United States, and Portugal (10–14 years; N = 1,233). Latent profile analyses identified relationship profiles that were culturally common or specific. Additional findings highlighted commonality in the relations between a high-quality relationship profile and adaptive functioning, as well as cultural specificity in the buffering and differential effects of distinct relationship profiles on social-behavioral outcomes. 相似文献

We incorporated clay modeling into gross anatomy and neuro‐anatomy courses to help students understand cross‐sectional anatomy. By making clay models, cutting them and comparing cut surfaces to CT and MR images, students learned how cross‐sectional two‐dimensional images were created from three‐dimensional structure of human organs. Most students in a clay modeling group responded positively to this approach, and their average score on CT examination was higher than that of a group that did not use clay models. Clay modeling appears to be a useful supplement to conventional anatomy or radiologic anatomy education. It can be applied to any part of human body, and its effectiveness will be greater when a more complicated understanding of cross‐sectional anatomy is required.

Inventing is a recombinant process that involves searching and recombining different streams of knowledge. The value of invention is associated with not only how many prior inventions are considered, but also how they are related to each other. We introduce social network analysis broadly used in the social capital theory, and extend the dimension of analysis for the evaluation of patent value. This study employs U.S. pharmaceutical patent data and investigates whether the network characteristic of backward citations have significant effect on the future patent value. The empirical results suggest that the network features of backward citations measured by constraint, cohesion, and efficiency have statistically significant implication on the value of invention in both level and depreciation rate. The study also provides empirical evidence that the exploration strategy is more significantly and positively correlated with the future value of invention compared to the exploitation strategy of inventors. 相似文献

The purpose of this study was to examine the types of instruments being used to document mathematics and science teacher quality characteristics in 48 nationally funded mathematics and science education awards. Each of the 48 projects operationalized teacher quality and determined how to assess it. The main research questions examined the instruments awardees used to gather data on mathematics and science teacher quality, and the main characteristics of teachers examined by awardees. Results showed that awardees most frequently used surveys or questionnaires to assess characteristics of mathematics and science teacher quality. The most common teacher characteristics examined by awardees' included teacher behaviors, practices, and beliefs, followed by the assessment of subject and pedagogical knowledge, and the documentation of mathematics and science teachers' certification. A few new instruments were under development and in use to assess characteristics of teacher quality. Detailed information on the development and psychometric properties of the instruments used for these examinations was not available from the reports. Because awardees were at different stages in their funded activities and data collection efforts were ongoing at the time of this analysis, this study offers a preliminary and formative review of the use of assessments to document mathematics and science teacher quality characteristics among these awards. 相似文献

Design research (DR) has been an emerging research paradigm in the field of educational technology as well as in education generally for two decades. Educational design research integrates design and research into a socially responsible approach to inquiry related to learning and teaching. Given its still relative novelty, design research requires further discussion regarding what it is and how it can be effectively executed. Instructional Systems Design (ISD) is one of the major activities carried out by educational technologists. Both ISD and design research deal with the enactment of design to improve educational practice. This paper describes the differences and similarities between these two activities and addresses the implications of these differences and similarities for educational technology researchers and practitioners. 相似文献

Abstract This article reviews previous research and reports on a study relating to six factors relevant to achievement in learning a new language: motivation, language learning styles, language learning strategies, gender, course level, and previous experience in learning a foreign language. Although motivation, learning styles, gender, and learning strategy use were all found to be influential, motivation was the single most important predictor of success. The authors suggest that awareness and understanding of the influence and interaction of student characteristics on achievement will allow instructors to provide optimal learning opportunities for all students. 相似文献
