Weekly self-efficacy and work stress during the teaching practicum: A mixed methods study

The purpose of this longitudinal mixed methods study was to examine the development of self-efficacy and work stress of pre-service teachers during a teaching practicum. Participants were 150 pre-service teachers who completed eight weekly electronic surveys during their two-month final practicum in a Canadian teacher education program. The study investigates the patterns of self-efficacy and work stress during a critical period in the formation of new teachers. Latent growth curve analysis revealed a pattern of significantly increasing self-efficacy and significantly decreasing stress, although the trajectories were independent of each other. Qualitative analysis of multiple collective cases highlighted the variability of self-efficacy and stress patterns within the practicum experience, and underscored the critical influence of relationships with mentor teachers on self-efficacy and stress.     

The occupational commitment and intention to quit of practicing and pre-service teachers: Influence of self-efficacy, job stress, and teaching context

The purpose of the present study was to explore the occupational commitment and quitting intention of practicing and pre-service teachers. We used a cross-sectional survey design to examine the impact of teachers’ self-efficacy, job stress, and contextual factors on occupational commitment and quitting intention of 434 practicing teachers and 379 pre-service teachers. Results revealed that similar factors—self-efficacy, job stress, and teaching context—influence the occupational commitment and quitting intention of practicing and pre-service teachers. Pre-service teachers displayed higher levels of commitment and less overall stress than practicing teachers. We conclude the article with implications for theory and practice, and suggest avenues to extend this line of career stage research.

教师职业压力的影响因素及内在心理机制

文章从需要和动机、认知方式、人格特征、能力素质、自我期望、经验、心理准备状态等方面阐述了影响教师职业压力的内部心理因素和影响教师职业压力的社会因素——社会支持系统;分析认为,教师职业压力从产生到发展经历几个阶段：环境刺激→对压力情境的评估→应付策略的运用→严重压力症状的产生→反馈机制的制约,完善了教师职业压力的内在心理机制模式图,进一步揭示了教师职业压力的本质和压力产生的一般规律。     

参灵糖浆对抗小鼠运动性疲劳的实验研究

目的:观察参灵糖浆对小鼠机体运动性疲劳的影响。方法:采用小鼠运动耐力实验、耐寒实验、耐缺氧实验,观察参灵糖浆对小鼠应激能力的影响;并建立疲劳模型,测定血乳酸及尿素氮含量,观察参灵糖浆对小鼠的抗疲劳作用。结果:参灵糖浆能明显提高小鼠的运动耐力、耐寒及耐缺氧能力,降低定量负荷后血乳酸及尿素氮水平。结论:参灵糖浆对小鼠有抗疲劳作用。     

有氧训练及热应激对运动大鼠肾脏组织NO、NOS及自由基代谢的影响

目的：探讨有氧耐力训练对运动热应激大鼠肾脏组织NO、NOS及自由基代谢的影响。方法：对大鼠进行为期6w的递增负荷运动训练,并在运动末次施加热应激,测定大鼠肾脏组织NO、NOS、MDA和SOD含量或活性。结果：（1）运动加热应激使大鼠肾脏组织NO、NOS、iNOS和MDA显著高于安静组和急性运动组,SOD和SOD／MDA显著低于安静组和急性运动组;（2）训练安静组与安静对照组相比,MDA均显著下降,NO、NOS均显著上升;（3）训练后运动热应激大鼠肾脏组织NO、NOS、iNOS、MDA显著下降,SOD显著上升。结论：（1）在热环境下运动,机体NO、NOS和自由基代谢增加,抗氧化酶活性下降;（2）在常温下进行有氧耐力训练练,可以适当提高机体的耐热性,降低运动热应激对机体的损伤。

运动应激对HPG轴下丘脑-垂体系统的影响和适应

不同种类运动应激对HPG轴下丘脑-垂体系统产生不同的影响,而机体的HPG轴下丘脑-垂体系统也产生不同的适应性变化,作为反映HPG轴下丘脑-垂体系统功能的代表性指标GnRH、LH和FSH有不同的变化趋势。本文对其变化的趋势及机理进行了探讨。     

篮球运动员比赛应对方式量表的编制

高水平竞技体育比赛中运动应激的应对问题正逐步成为国内外运动心理学研究的热点.从环境研究思路出发,编制了我国篮球运动员比赛应对方式测评量表.运行探索性和验证性因素分析后表明: 篮球运动员比赛应对方式主要有四种类型,即直接行动、情绪宣泄、重新计划和逃避;该量表具有较好的信度和效度,可以作为评估我国篮球运动员比赛应对方式的测评工具.此外,还初步整理出成年队和青年队常模,这为准确地分析和评定运动员个体的应对方式以及对不良应对方式的治疗性干预提供了参考依据.
