Nonscience majors learning science: A theoretical model of motivation     

Shawn M. Glynn  Gita Taasoobshirazi  Peggy Brickman 《科学教学研究杂志》2007,44(8):1088-1107

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

Residual stress analysis and bow simulation of crystalline silicon solar cells

The pressure to reduce solar energy costs encourages efforts to reduce the thickness of silicon wafers. Thus, the cell bowing problem associated with the use of thin wafers has become increasingly important, as it can lead to the cracking of cells and thus to high yield losses. In this paper, a systematic approach for simulating the cell bowing induced by the firing process is presented. This approach consists of three processes: (1) the material properties are determined using a nanoidentation test; (2) the thicknesses of aluminum (Al) paste and silver (Ag) busbars and fingers are measured using scanning electron microscopy; (3) non-linear finite element analysis (FEA) is used for simulating the cell bowing induced by the firing process. As a result, the bowing obtained using FEA simulation agrees better with the experimental data than that using the bowing calculations suggested in literature. In addition, the total in-plane residual stress state in the wafer/cell due to the firing process can be determined using the FEA simulation. A detailed analysis of the firing-induced stress state in single crystalline silicon (sc-Si), cast, and edge-defined film-fed growth (EFG) multi-crystalline silicon wafers of different thicknesses is presented. Based on this analysis, a simple residual stress calculation is developed to estimate the maximum in-plane principal stress in the wafers. It is also proposed that the metallization pattern, Ag busbars and fingers screen printed on the front of a solar cell, can be designed using this approach. A practical case of a 3-busbar Si solar cell is presented.  相似文献   

Predicting reading achievement for Kindergarten boys and girls     

Nona Tollefson  Roberto Rodriquez  Peggy Glazzard 《Psychology in the schools》1985,22(1):34-39

This study assessed the validity of the Kindergarten Teacher Rating Scale (KTRS) in predicting reading achievement for male and female students. The KTRS was a significant predictor of reading achievement for both boys and girls; differential predictive validity for boys and girls was not found. The KTRS explained about 30% of the variance in reading achievement both at the end of the 1st grade and the beginning of 2nd grade. The proportion of variance in reading achievement explained by variance in KTRS scores was significantly greater than the proportion of variance in reading achievement explained by variance in reading readiness scores. There were no significant differences in the mean KTRS scores for male and female students.  相似文献   

Teaching Instructional Design: An Apprenticeship Model     

Peggy A. Ertmer  Katherine S. Cennamo 《Performance Improvement Quarterly》1995,8(4):43-58

Several cognitive psychologists have written about the importance of placing instruction within “authentic” contexts that mirror real-life situations. They argue that knowledge learned in academic settings does not necessarily transfer to non-academic settings. Whether preparing performance technologists or instructional designers, educators must strive to create meaningful problem-solving contexts that enable students to define, and subsequently solve, real-world problems. In an attempt to address this issue we have modified the way we teach instructional design. This paper discusses a cognitive apprenticeship approach to teaching design, which incorporates elements of modeling, coaching, reflection, articulation, and exploration. We describe how these features are embedded within three phases (orientation, situated training/learning, and exploration) of an introductory instructional design course designed to move our novice designers along a continuum of expertise as they develop and refine their own professional design skills. Although the apprenticeship model described here specifically addresses concerns within the context of preparing instructional designers, we believe that this model can be adapted to address similar issues in the education of performance technologists.  相似文献   

The effects of amount and type of teacher-child interaction on child-child interaction during free-play     

Richard E. Shores  Peggy Hester  Phillip S. Strain 《Psychology in the schools》1976,13(2):171-175

Social interactions between preschool behaviorally handicapped children were measured under three experimental conditions during free-play: (a) active teacher involvement in free-play, (b) no teacher involvement in free-play, and (c) teacher structured free-play. Significantly more child-child interactions occurred during teacher structured free-play than in either of the other two conditions, with the no teacher involvement condition producing significantly more child-child interactions when compared to the active teacher involvement condition. Additionally, significantly more teacher-child interactions occurred during the active teacher involvement condition than in either of the other two conditions, with nonsignificant differences in teacher-child interaction between the no teacher involvement and the teacher structured conditions. The results are discussed in terms of their implications for ameliorating social interaction deficits among young behaviorally handicapped children.  相似文献
