The Educational and Career Interest scale, a self-report instrument measuring high school students’ educational and career interest in STEM, was developed and validated in two studies conducted during 2010 and 2011. Study 1 included data from 92 high school students, in which exploratory factor analysis (EFA) was conducted with an initial item pool of 20 items. EFA identified three factors: educational and career interest in science, educational and career interest in technology, and educational and career interest in mathematics. Study 2 utilized data from 658 students to revisit the three-factor model using confirmative factor analysis. The two studies provide strong evidence that the scale is both valid and reliable. 相似文献

Play is considered an important activity of the early childhood years. Research supports the contribution of play to children’s development, learning, and well-being. In spite of this, time for play is being pushed out in many early childhood programs by greater time allotted to formal instruction in narrow academic skills to be tested eventually by standardized tests. As a result, current preservice teachers are likely to see fewer examples of appropriate time and support for play in their field placements in early childhood settings. The purpose of this study was to document and analyze what happens when an experiential play lab is implemented in an early childhood teacher education program. This qualitative study includes multiple forms of data collection, including two forms of reflective writings and group discussions. After the workshop, preservice teachers made a greater number of references to play in their defense of developmentally appropriate practice, and the nature of their references to play increased in their focus on play process and on teacher roles in children’s play, as compared to prior to the lab. The results of this study of an experiential play intervention support its potential as a means of probing, documenting, and enriching students’ understanding of the importance of providing for and supporting play in classrooms for young children. 相似文献

The purpose of this study was to develop an index to assess and evaluate the competitive advantage of a country’s human resource development system. Based on an extensive literature review, a theoretical model of a human resource development system at the national level (named National Human Resource Development: NHRD) was constructed. The model consists of four factors—supply conditions, demand conditions, environment, and supporting systems—and NHRD system competitiveness was measured by the cumulative sum of a country’s achievement in each of these four factors. The four factors were divided into 10 sub-categories, and 45 indicators were selected based on criteria such as relevance, international comparability, reliability, timeliness, and accessibility. Finally, by using the Analytic Hierarchy Process, the individual weights of the 45 indicators were calculated. In addition, the relationships between the NHRD competitiveness scores of OECD member countries and other relevant variables, including GDP per capita and the scores from other national competitiveness studies, were analyzed to examine the validity of the index. 相似文献

This research investigates how disciplinary contexts, institutional settings, and individual motivations all affect researchers' depositing their articles into an institutional repository (IR). This study employed the Theory of Planned Behavior as its main theoretical framework and proposed six hypotheses to explain how disciplinary, institutional, and individual factors influence researchers' article depositing behaviors through an IR. This research utilized an online survey as its data collection method, and a total of 221 survey responses from researchers in U.S. academic institutions were collected. The hypothesized relationships were then tested by using multiple regression analysis. This research found that perceived community benefit, perceived institutional support, and perceived career benefit significantly increases researchers' article depositing behaviors through an IR, and the perceived career risk significantly decreases researchers' article depositing behaviors through an IR. This research suggests that community benefit, institutional support, and career issues need to be considered to increase researchers' overall article sharing behaviors through an IR. 相似文献

This paper presents an analysis of educational technology research with specific emphasis on determining how the research goals pursued and methods used have evolved over the 25-year period from 1989 through 2014. For this study, the contents of the Educational Technology Research and Development journal were analyzed over two six-year periods, first from 1989 to 1994 and second from 2009 to 2014, to identify the goals and methods of the studies specifically designated in the journal as “research papers.” Results indicate trends in the goals and methods employed in educational technology research that have implications for future research directions as well as for the preparation of graduate students and early career scholars to conduct educational technology research. 相似文献

Teacher–student relationships have been linked to autonomous motivation and achievement. However, relatively little is known about whether satisfying students’ psychological needs mediates the association between teacher–student relationships and student happiness. Furthermore, this relationship needs to be examined in samples of students from different ethnic and racial backgrounds. In this structural equation modeling study (N = 1,961), we found that teacher–student relationships were positively and moderately associated with the satisfaction of psychological needs for autonomy, relatedness, and competence. Satisfying psychological needs, in turn, was moderately positively associated with happiness. These findings held across African American, Asian American, and Latinx subsamples. For the overall sample, students in higher grade levels perceived that their psychological needs were met to a lesser degree than students in earlier grades. However, only the Latinx subsample replicated this effect. Teacher–student relationships may promote happiness via meeting psychological needs. 相似文献

The integration of digital game-based learning environment (DGBLE) enhanced by technology in recent years has been hampered by its complexity and difficulty in realistically addressing teachers’ instructional needs. The pedagogical gap between what teachers think a DGBLE can deliver and what DGBLE can actually offer remains substantial. To preliminarily address the gap, this present qualitative study adopted an end-user-development lens to understand how K-12 teachers as novice end users interpret and design game features in their DGBLEs. The design ideas, situated in teaching scientific subjects, were collected from 19 pre-service teachers in a public university in the United States by semi-structured interviews based on game features identified in the literature. The data analysis, grounded in the ARCS (attention, relevance, confidence, satisfaction) motivational design model, employed the direct content analysis method and revealed the distribution of motivational support among participants’ DGBLEs design ideas. The finding suggested that participants were more likely to incorporate intrinsic motivational support than extrinsic support in their design. This trend could compromise the motivational support of DGBLEs when students need additional extrinsic motives toward the end of learning processes. Further, the study illuminates the importance of incorporating end users’ perspectives early on in the DGBLE design process. 相似文献
