This article reports on the study of the components of scientific imagination and describes the scales used to measure scientific imagination in Korean elementary and secondary students. In this study, we developed an inventory, which we call the Scientific Imagination Inventory (SII), in order to examine aspects of scientific imagination. We identified three conceptual components of scientific imagination, which were composed of (1) scientific sensitivity, (2) scientific creativity, and (3) scientific productivity. We administered SII to 662 students (4th–8th grades) and confirmed validity and reliability using exploratory factor analysis and Cronbach α coefficient. The characteristics of Korean elementary and secondary students' overall scientific imagination and difference across gender and grade level are discussed in the results section. 相似文献

Socioeconomic status (SES) is often used as control variable when relations between academic outcomes and students' migrational background are investigated. When measuring SES, indicators used must have the same meaning across groups. This study aims to examine the measurement invariance of SES, using data from TIMSS, 2003. The study shows that a latent SES variable has the same meaning across sub-populations with Swedish and non-Swedish background. However, the assumption of scalar invariance was rejected, which is essential for estimation of differences in latent means between groups. Comparisons between models assuming different degrees of scalar invariance indicated that models allowing partial scalar invariance should not be used when comparing latent variable means across groups of students with different migrational backgrounds. 相似文献

School self-evaluation (SSE) is an effective mechanism that helps schools to put in place strategies to improve an aspect of school quality. By implementing an action research study of SSE in 24 Chinese secondary schools across seven cities since 2011, the present study generalizes and proposes an operationalized and effective SSE system to illustrate how to operationalize SSE effectively. The system was developed in three essential parts: (a) constructing the measurement model of SSE, which included identifying the framework and indicators to determine the primary evaluation contents, and designing operational evaluation modules to apply SSE indicators to school practices and integrate them into routine school operations; (b) establishing a cooperation mechanism between internal SSE groups and external “facilitative friends” to conduct SSE with different roles allocated; and (c) summarizing detailed implementation procedures and key strategies to implement a cyclical, regular and sustainable SSE process step by step. 相似文献

Expectancy-value researchers have described the components of subjective task value in multiple ways, leading to multiple competing structural representations of subjective task value data. The purpose of this study was to examine these competing multidimensional factor structures by comparing correlated factor, hierarchical, and bifactor representations of both confirmatory factor analysis and exploratory structural equation modeling (ESEM) models across three theoretical conceptualizations of subjective task value. Results indicate that, in an undergraduate life science learning context (n = 334), the best representation for subjective task value data was a bifactor ESEM model that allowed for the disentangling of general and specific variance of general subjective task value, specific value beliefs, and specific costs. Full measurement invariance of the retained structure across continuing generation and first-generation students was found, and no differential item functioning was found across gender. General subjective task value and specific opportunity cost significantly and positively predicted achievement and specific utility value significantly and negatively predicted achievement, providing support for the criterion-related validity of the general and specific factors for predicting achievement outcomes. 相似文献
