We examined cognitive attributes, attention, and self‐efficacy of fourth grade struggling readers who were identified as adequate responders (n = 27), inadequate responders with comprehension only deficits (n = 46), and inadequate responders with comprehension and word reading deficits (n = 52) after receiving a multicomponent reading intervention. We also included typical readers (n = 40). These four groups were compared on measures of nonverbal reasoning, working memory, verbal knowledge, listening comprehension, phonological awareness, and rapid naming as well as on teacher ratings of attention problems and self‐reported self‐efficacy. The two inadequate responder groups demonstrated difficulties primarily with verbal knowledge and listening comprehension compared to typical readers and adequate responders. Phonological awareness and rapid naming differentiated the two inadequate responder groups. In addition, both inadequate responder groups showed more attention problems and low self‐efficacy compared to typical readers.  相似文献

Pre-service teachers’ motivation,sense of teaching efficacy,and expectation of reality shock     

Hyunjin Kim  YoonJung Cho 《Asia-Pacific Journal of Teacher Education》2014,42(1):67-81

The present study investigated how pre-service teachers’ motivation and their sense of teaching efficacy influence their expectation about reality shock during the first year of professional teaching. A total of 533 pre-service teachers at a state university in the US Midwest participated in this study. The results showed that the pre-service teachers’ expectation of reality shock was negatively related to teacher efficacy and intrinsic motivation while it was positively related to introjected and external motivation. The results of a hierarchical regression analysis revealed that pre-service teachers’ sense of efficacy and introjected motivation were strong predictors of their expectation of reality shock, when gender difference was controlled for. There was an interaction effect between intrinsic motivation and teachers’ sense of efficacy in predicting the reality shock expectation. We discussed the educational implications for future research in an endeavour to reduce the reality shock among novice teachers.  相似文献   

Introduction of Molecular Methods into a Food Microbiology Curriculum     

Aaron M. Pleitner  Susan R. Hammons  Emily McKenzie  Young‐Hee Cho  Haley F. Oliver 《Journal of Food Science Education》2014,13(4):68-76

Maintaining current, relevant curriculum in undergraduate Food Microbiology courses is essential for training future experts in food quality and safety. Having an understanding of the fundamental techniques (for example, polymerase chain reaction [PCR]) that are used in the food industry and regulatory agencies is critical for students entering the workforce. The purpose of this study was to assess the efficacy of integrating molecular methods into an undergraduate Food Microbiology course in both lecture and laboratory settings. Modules on PCR and pulsed‐field gel electrophoresis (PFGE), both of which are currently used by government agencies and the food industry to investigate the presence and persistence of foodborne pathogens, were developed, introduced, and evaluated among 269 students over 4 y. Multiple teaching and learning styles were incorporated through (i) traditional lecture format on the basics of PCR and PFGE; (ii) hands‐on group activities to build upon the lecture instruction; (iii) performing PCR and PFGE in the laboratory; and (iv) group discussions to analyze results from laboratory exercises. Pre‐ and postinstruction evaluations revealed significant increases in understanding and application of both methods in lecture and laboratory settings as demonstrated by 0.60 and 0.51 mean normalized gains for respective PCR and PFGE lectures and 0.50 and 0.56 mean normalized gains in respective labs. Academic year significantly impacted score improvement, potentially due to hidden factors, such as previous exposure to material and student aptitude. This study provides the platform for successful introduction of molecular techniques in an undergraduate Food Microbiology course. The guidelines and materials developed by our group are publicly available for use by other institutions.  相似文献

INTRODUCTION Being the bio era, a significant research effort has been devoted to the study of proteins since they are related to the critical body functions. There have been many studies on proteins, with the voluminous related data being currently available in various pub- lic repositories including the Protein Data Bank (PDB) (CATH, 2006; DALI, 2006; MSD, 2006; RCSB PDB, 2006; SCOP Database, 2006). Given the atomic complexes of proteins, ana- lyzing interactions between them…  相似文献

Exploring the parallelism between change in students' conceptions and historical change in the concept of inertia     

Dr Jinwoong Song  Sook-Kyoung Cho  Byung-Hoon Chung 《Research in Science Education》1997,27(1):87-100

This study investigates students' conceptions of inertia and compares these conceptions with historical change in the concept. A total of 736 students from four different age groups (i.e., age 11, 13, 15 and 17) participated in the survey. Questions in the questionnaire represent problems related to the concept of inertia which have been argued by past scientists such as Aristotle, Buridan, Galileo, and Newton. The questionnaire contained three questions, each concerned with one of the following applications of inertia: natural motion, the motion of a flying spear, and the falling motion of a stone on a moving ship. The results of the survey showed that there were considerable similarities as well as dissimilarities between students' conceptions and the views of past scientists. It is suggested that this kind of comparison studies would give useful background information on change in students' conceptions. To this day every student of elementary physics has to struggle with the same errors and misconceptions which then had to be overcome, and on a reduced scale, in the teaching of this branch of knowledge in schools, history repeats itself every year.

INTRODUCTION Today, the manufacturing industry makes con- stant effort in order to construct an E-manufacturing system using information technology for effective production control, and then, it offers the integrated production control to the workers, the production managers, and the consumers, etc. (Lee, 2003; Choi, 2004). In the mould manufacturing industry, the process managers often request paperwork to know the information of the processes on CNC machine tools or they visit the shop…  相似文献   

Foot and ankle joint movements of dancers and non-dancers: a comparative study     

Ho-Jung Cho  Soyeon Kim  Joon-Yong Jung 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(6):587-594

Ballerinas use their ankle joints more extremely and sustain injuries on the ankle joint more frequently than non-dancers. Therefore, the ankle movement of dancers is important and should be studied to prevent injuries. Measuring ankle joint range of motion (ROM) using radiographs could demonstrate the contribution to motion of each joint. The aim of this study was to analyse and compare ankle joint movements and the ratio of each joint’s contribution during movement between dancers and non-dancers, using radiographic images. Dancers have lower dorsiflexion (26.7 ± 6.2°), higher plantarflexion (74.3 ± 7.1°) and higher total (101.1 ± 10.8°) ROMs than non-dancers (33.9 ± 7.0°, 57.2 ± 6.8° and 91.1 ± 9.3°, respectively) (p < 0.05). Although the ROMs were different between the two groups, the ratios of each joint movement were similar between these two groups, in all movements. Regarding total movement, the movement ratio of the talocrural joint was almost 70% and other joints accounted for almost 30% of the movement role in both dancers and non-dancers. Therefore, the differences in ROM between dancers and non-dancers were not a result of a specific joint movement but of all the relevant joints’ collaborative movement.  相似文献   

Learning by self-explaining causal diagrams in high-school biology     

Young Hoan Cho  David H. Jonassen 《Asia Pacific Education Review》2012,13(1):171-184

Understanding scientific phenomena requires comprehension and application of the underlying causal relationships that describe those phenomena (Carey 2002). The current study examined the roles of self-explanation and meta-level feedback for understanding causal relationships described in a causal diagram. In this study, 63 Korean high-school students were randomly assigned to one of three conditions: instructional explanation, self-explanation, and meta-level feedback. Results showed that self-explaining a causal diagram was as effective as studying instructional explanations. Furthermore, the effectiveness of self-explaining a causal diagram was enhanced by meta-level feedback that prompted students to reflect on their own explanations by comparing them with instructional explanations. We identified three main difficulties that high-school students experienced when explaining a causal diagram to themselves: one-sided explanation, erroneous explanation, and the lack of inference. Implications of the study were discussed in regard to the improvement of self-explanation and the design of causal diagrams in science education.  相似文献
