The development of the nature of science view scale (NOSvs) at university level

Background: Determining individuals’ views of the nature of science is quite important for researchers since it is both a component of scientific literacy and a fundamental aim of science education.

Purpose: This study aims to develop a NOSvs for assessing prospective teachers’ views of the nature of science and to analyse their psychometric properties.

Sample: A total of 565 prospective teachers participated in the study.

Design and methods: The Kaiser–Meyer–Olkin (KMO) Index and Bartlett’s Sphericity Test were used in this study. Confirmatory factor analysis (CFA) was performed to determine the construct validity of the scale. Cronbach’s Alpha (α) coefficient was calculated for the reliability of the study.

Results: It was consequently found that the KMO was larger than .50. That Bartlett’s Sphericity Test was also statistically significant. The items with item-total correlations smaller than .30 were removed from the scale. Cronbach’s α values calculated for each sub-scale were above .70. In consequence of the first CFA performed, fit indices were found to be below the expected level. For this reason, three more items with the least item-total correlations were removed from the scale. Following the CFA, the final form of the scale included 36 items and five sub-scales.

Metaphorical images of schooling: beliefs about teaching and learning among prospective teachers from the United States displaying different motivational profiles

This study focused on investigating the types of schooling beliefs (teaching and learning) expressed through metaphorical images by prospective teachers (PTs) from the United States. Participants (N = 215) rated 10 schooling metaphors illustrating the student–school–teacher relationships (i.e. Passenger–Bus–Driver; Student is a passenger, School is a bus and Teacher is a driver). Two main factors, a student-centred and a teacher-centred approach described the key schooling beliefs of PTs. Additionally, differences in PTs’ schooling beliefs across typologies/clusters of PTs were found. Further, qualitative data from interviews illustrated how each cluster specifically expressed their instructional views.

1922年右派社会革命党人审判案

社会革命党是俄国的一大革命政党。进行过反对沙皇制度的英勇斗争。十月革命后反对布尔什维克党的政策。为消除该党在俄国人民,特别是农民中的影响,1922年举行了对右派社会革命党人的审判。社会革命党人则利用法庭公开宣传自己的主张,毫不改悔。审判在国际上引发强烈抗议。虽然判处了一些被告死刑,但没有执行,最后不了了之。

完善试用期的录用条件 减少劳动合同的解除成本

《劳动合同法》实施以来,新的规定对企业现行的人力资源管理办法、劳动关系及用工策略等提出了挑战。如何运用新的法律规定签订一份能规避法律风险、减少用工成本和解雇成本的合同,是摆在用人单位面前的新课题。本文就如何完善试用期间的录用条件,最大限度地减少用人单位解除劳动合同的成本问题,围绕招聘工作的录用条件、合同的审查、订立、解除、离职管理进行了探讨。
