Science Teaching Efficacy of Preservice Elementary Teachers: Examination of the Multiple Factors Reported as Influential

This study explores the science teaching efficacy beliefs of pr-service elementary teachers and the relationship between efficacy beliefs and multiple factors such as antecedent factors (participation in extracurricular activities and number of science and science teaching methods courses taken), conceptual understanding, classroom management beliefs and science teaching attitudes. Science education majors (n?=?71) and elementary education majors (n?=?262) were compared with respect to these variables. Finally, the predictors of two constructs of science teaching efficacy beliefs, personal science teaching efficacy (PSTE) and science teaching outcome expectancy (STOE), were examined by multiple linear regression analysis. According to the results, participation in extracurricular activities has a significant but low correlation with science concept knowledge, science teaching attitudes, PSTE and STOE. In addition, there is a small but significant correlation between science concept knowledge and outcome expectancy, which leads the idea that preservice elementary teachers’ conceptual understanding in science contributes to their science teaching self-efficacy. This study reveals a moderate correlation between science teaching attitudes and STOE and a high correlation between science teaching attitudes and PSTE. Additionally, although the correlation coefficient is low, the number of methodology courses was found to be one of the correlates of science teaching attitudes. Furthermore, students of both majors generally had positive self-efficacy beliefs on both the STOE and PSTE. Specifically, science education majors had higher science teaching self-efficacy than elementary education majors. Regression results showed that science teaching attitude is the major factor in predicting both PSTE and STOE for both groups.

Comparing the job satisfaction of hourly paid and salaried preschool teachers in Turkey

This two-phase mixed-methods study compares the job satisfaction of Turkish preschool teachers who are paid hourly against the satisfaction of those on regular contracts. The participants in its first, quantitative phase were 260 preschool teachers, of whom 81 also participated in the second, qualitative phase. Initial data collection from all phase-one participants was via the Job Satisfaction Scale. Then, in phase two, the members of the hourly paid group were asked three open-ended questions, and the regular-contract teachers two of the same questions, related to the advantages and disadvantages of hourly paid teaching. The results indicated a significant difference in job satisfaction levels between the two types of teachers. None of the interactive effects between preschool teachers’ working status and their gender, age, marital status, and in-service training was statistically significant. In phase two, moreover, more than half of the 41 hourly paid teachers (n?=?22) emphasised that they worked as hourly for economic reasons, while more than a third (n?=?30) of the overall phase-two sample stated that there was no advantage of working as an hourly paid teacher. Working conditions for hourly paid teachers were described as disadvantageous by almost half the members of the phase-two sample (n?=?37).

荣格的集体无意识学说与杰克·伦敦的《野性的呼唤》

中篇寓言体小说《野性的呼唤》是美国著名作家杰克·伦敦在惊人的无意识亢奋状态下创作出来的一部幻觉性的作品。不管杰克·伦敦本人的创作意图如何,他的这部杰作与荣格的集体无意识学说完全相吻合。本文在迈克思维尔.盖斯玛和厄尔.莱柏两位著名评论家所持观点的基础上,运用荣格的集体无意识学说对《野性的呼唤》进行心理分析,以证明主人公巴克是在其自性的引导下,经过艰难的个性化过程,从其有意识的自我中解脱出来并达到自我实现的。
