Production of a Science Documentary and its Usefulness in Teaching the Nature of Science: Indirect Experience of How Science Works     

Sun Young Kim  Sang Wook Yi  Eun Hee Cho 《Science & Education》2014,23(5):1197-1216

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, “Life as a Scientist: People in Love with Caenorhabditis elegans, a Soil Nematode” encompasses the entire process of a scientific investigation by exploring the everyday life of a particular group of scientists. We explored the effectiveness of this documentary in teaching the nature of science by examining the epistemological views of college students toward science before and after viewing. In addition, we collected written responses from the students where they described which aspect of the nature of science they learned from the documentary. The scores of epistemological views toward science increased between the pretest and the posttest (p < 0.01) with the most significant increase being in their views of the role of social negotiation. In the written responses, approximately half of the students suggested that they had learned more about the role which cooperation and collaboration play in the development of scientific knowledge by watching the documentary. The documentary overall provides a valuable instructional context so that students are able to discuss and reflect on various aspects of nature of science within authentic scientific research.  相似文献   

The recent trends of information organization research in Japan and Korea     

Jane Cho 《Library Collections, Acquisitions, and Technical Services》2013,37(3-4):107-117

In order to analyze and compare the intellectual structure of information organization research in Japan and Korea, this study has carried out frequency analysis and network text analysis of research articles published in the last two years. Analysis showed that the Japanese information organization area has a high frequency of research centered on the concepts of “catalog” and “classification”. In particular, “catalog” is seen to have a high figure in degree centrality by network text analysis, it can be said that the “catalog” concept has extensive connections with a diverse range of subjects in the area of information organization. On the other hand, the Korean information organization research area showed a high frequency and connectivity of subjects related to “classification” rather than “catalog”. The “classification” concept is seen to have extensive connections with other various subjects in the Korean information organization research area.  相似文献   

Influence of Family Processes,Motivation, and Beliefs About Intelligence on Creative Problem Solving of Scientifically Talented Individuals     

Seokhee Cho  Chia-Yi Lin 《Roeper Review》2013,35(1):46-58

Predictive relationships among perceived family processes, intrinsic and extrinsic motivation, incremental beliefs about intelligence, confidence in intelligence, and creative problem-solving practices in mathematics and science were examined. Participants were 733 scientifically talented Korean students in fourth through twelfth grades as well as 71 individuals in fifth grade, tenth grade, and former Korean Science Olympians. Across all students, perceived positive family processes directly predicted creative problem-solving practices in mathematics and science and were indirectly predicted through enhancing confidence in intelligence and intrinsic motivation, which, in turn, predicted students' creative problem solving in mathematics and science. Confidence in intelligence was the best predictor of creative problem solving for scientifically talented fifth- and tenth-grade students but not for Olympians. Alternative interpretations, the importance of confidence in intelligence for creative problem solving in mathematics and science, and educational implications are discussed.  相似文献

Meeting the Needs of High School Science Teachers in English Language Learner Instruction     

Seonhee Cho  Jacqueline T. McDonnough 《Journal of Science Teacher Education》2009,20(4):385-402

This survey study explored high school science teachers’ challenges and needs specific to their growing English language learning (ELL) student population. Thirty-three science teachers from 6 English as a Second language (ESL)-center high schools in central Virginia participated in the survey. Issues surveyed were (a) strategies used by science teachers to accommodate ELL students’ special needs, (b) challenges they experienced, and (c) support and training necessary for effective ELL instruction. Results suggest that language barriers as well as ELL students’ lack of science foundational knowledge challenged teachers most. Teachers perceived that appropriate instructional materials and pedagogical training was most needed. The findings have implications for science teacher preservice and inservice education in regard to working with language minority students.

Does Teaching Experience Matter? The Beliefs and Practices of Beginning and Experienced Physics Teachers     

Imelda S. Caleon  Yuen Sze Michelle Tan  Young Hoan Cho 《Research in Science Education》2018,48(1):117-149

This study utilized multiple data sources to examine the beliefs about learning and teaching physics and the instructional practices of five beginning teachers and seven experienced teachers from Singapore. Our study was implemented in the unique context of teachers teaching the topic of electricity to students grouped according to academic abilities. The topic of electricity is one of the most difficult physics topics for students to understand and for teachers to teach. It was found that the experienced teachers, compared to the beginning teachers, tended to have beliefs about teaching and learning physics that are closer to constructivist views. The majority of the teachers, particularly the beginning teachers, espoused beliefs about learning physics that were incongruent with their beliefs about teaching physics. Although transmission-oriented and teacher-directed practices dominated the classroom lessons of both groups of teachers, more elements of constructivist instruction were found in the classroom lessons of the experienced teachers. It was also found that the classroom practices of the teachers, especially those in their inductive years of teaching, were more aligned with their beliefs about learning physics than their beliefs about teaching physics.  相似文献   

Maternal literate mediation of writing and Korean children’s reading and writing across 1 year     

Jeung-Ryeul Cho  Catherine McBride 《Reading and writing》2018,31(3):679-701

The present study examined the relations of maternal literate support instructions during parent–child joint writing to children’s word reading and writing across 1 year among 95 4- and 5-year-old children from Korea. The whole episode of mothers individually teaching their children how to write words was videotaped, and a Korean scale of mothers’ literate mediation of their children’s writing was developed based on six cognitive strategies focusing on whole Gulja (Korean written syllable), visual strokes, letter, Gulja structure, and CV (consonant + vowel) and coda (final consonant of a syllable) subsyllabic units. Maternal literate support explained a significant amount of variance in children’s word reading and writing concurrently and longitudinally across 1 year after controlling for children’s age, nonverbal IQ, phonological and morphological awareness, rapid automatized naming and mother’s education. In addition, children’s coda phoneme awareness explained unique variance in word reading and writing concurrently and longitudinally. Results underscore the unique characteristics of Korean and the importance of Korean maternal literate support as a major factor in early literacy development.  相似文献   

Perceived competence and autonomy as moderators of the effects of achievement goal orientations     

YoonJung Cho  Claire Ellen Weinstein  Frank Wicker 《教育心理学》2011,31(4):393-411

The primary purpose of this study was to investigate the roles of two moderators – perceived competence and perceived autonomy – in the relationships of achievement goal orientations with a broad range of learning‐related variables, including interest, effort, learning strategy use and academic achievement. Perceived competence and autonomy played roles as moderators by strengthening the positive effects of a mastery goal pursuit on outcome measures of adaptive use of learning strategies and effort, respectively. However, no moderating role of either perceived competence or perceived autonomy was found for the effect of a performance‐approach and performance‐avoidance goal pursuit. In addition, perceived competence played a significant role in determining the level of academic achievement in the context of multiple‐goal pursuit. For students with high perceived competence, the adoption of high performance‐approach goals resulted in a higher level of achievement regardless of the levels of mastery goals. In contrast, students with low perceived competence showed the highest achievement when high performance‐approach goals are paired with low mastery goals.  相似文献   

Peer reviewers learn from giving comments   总被引：1，自引：0，他引：1  

Young Hoan Cho  Kwangsu Cho 《Instructional Science》2011,39(5):629-643

Research on peer reviewing has revealed that comments received from peer reviewers are helpful when it comes to making revisions in an individual’s writing, but the role of providing comments to peer writers has been little explored despite the potential value of such research. In this study, we explored how student reviewers learn by reviewing peer drafts in the context of reciprocal peer reviewing. Undergraduate students in an introductory physics course participated in this study as part of their course activities. Participants wrote technical research drafts, reviewed three or four peer drafts, and revised their own drafts in the SWoRD system. A total of 3,889 comment segments were analyzed in two dimensions: (a) evaluation (strength vs. weakness) and (b) scope (surface, micro-meaning, and macro-meaning). We found that providing weakness comments for micro-meaning and strength comments for macro-meaning improved the reviewers’ writing qualities. In addition, reviewers’ initial writing skills and the quality of reviewed peer drafts influenced the types of comments given. The results are discussed, along with their implications for improved writing through reviewing.  相似文献
