Benefits of personality characteristics and self‐efficacy in the perceived academic achievement of medical students     

Sabine Guntern  Hanke Korpershoek  Greetje van der Werf 《教育心理学》2017,37(6):733-744

This study investigates the joint impact of personality characteristics and self‐efficacy on the perceived academic achievement of medical students on top of their prior high school performance. The sample consisted of medical students in their pre‐clinical years. The students’ grade point average scores at high school were included as control variable in our explanatory models. Based on previous findings in the literature, we selected self‐discipline, social activity and emotional stability from the Five Factor Model of Personality as predictor variables. Furthermore, following the social cognitive theory of Bandura, we added self‐efficacy (students’ belief in their academic skills) as an additional predictor. The logistic regression analyses confirmed the importance of self‐discipline (positively related) and social activity (negatively related) for these students’ perceived academic achievement. Additionally, we found a positive contribution of self‐efficacy. The results of this study (as discussed in the final sections) have implications for support programmes in the practical field.  相似文献   

高中数学课堂活动教学的实践与思考     

黄兰妹 《钦州学院学报》2006,21(5):91-94

课堂活动教学是让课堂教学焕发生机与活力的重要教学形式。数学实验、设置问题解答、设置错误纠正等是课堂活动教学的有效形式。实施课堂活动教学要以学生为主体；要激发学生参与学习活动的欲望；要给学生主动发展提供广阔的时间和空间；要重视交流与合作；要提高活动教学的针对性。  相似文献

自闭症谱系障碍儿童早期脑结构发育异常及其神经机制     

王琳  王志丹  王畅 《中国特殊教育》2020,(3):55-61

自闭症谱系障碍是儿童发育早期出现的一种神经发展性疾病。近年来,基于婴幼儿同胞研究范式的脑神经科学研究发现,自闭症儿童发育早期会出现皮层表面积加速增大、脑脊液异常增加和脑白质结构异常,这些发现有助于追踪自闭症儿童大脑和核心行为症状的发育轨迹,预测自闭症早期的发生和后期的发展趋势。本文对自闭症儿童早期脑结构发育异常及其神经机制的研究进行了系统梳理,以期深入理解自闭症的发病机制,助益于自闭症的早期筛查、靶向干预和有效康复。  相似文献

智力心理活动的矛盾结构论要   总被引：1，自引：0，他引：1  

张永昌  辛志英 《石家庄学院学报》2004,6(4):9-13

要具体回答智力心理活动的矛盾结构,必须科学地划分心理活动及其要素;以心理活动的反映对象为根据,把心理活动及其要素划分为认知心理活动及其要素和价值心理活动及其要素;认知心理活动和价值心理活动的对立统一,构成了智力心理活动的矛盾结构;认知心理活动是智力心理活动的基础和必要条件,价值心理活动是智力心理活动的主导和充要条件。智力矛盾结构论的确立,必将对实验心理学、学校教育、人力资源开发和创新活动发挥更大推动作用。  相似文献

Playing with rules around routines: children making mealtimes meaningful and enjoyable     

Sophie Alcock 《Early Years: An International Journal of Research and Development》2007,27(3):281-293

Children attending early childhood education and care centres spend a lot of time fitting in with institutional routines. This paper uses ethnographic methods and sociocultural activity theory to describe and analyse the processes whereby young children in an early childhood centre collectively created meaning and interest during potentially boring routine mealtimes. The research explores the relationship between rules and children's playful activity. Using their imaginations children negotiated and played with and within the rules around ‘eating‐together’ times. While physically constrained in chairs around tables children enjoyed the freedom of playing with word sounds and meanings. Children actively, collaboratively and at times subversively, created their peer community culture.  相似文献

Attrition resistant catalyst for dimethyl ether synthesis in fluidized-bed reactor   总被引：1，自引：0，他引：1  

Li-hua Teng 《浙江大学学报(A卷英文版)》2008,9(9):1288-1295

Fluidized-bed reactor is a candidate for dimethyl ether （DME） synthesis from syngas because of its excellent heat removal capability. In order to improve the attrition resistance of catalyst, an amount of silica sol as binder was added to the catalyst composed of methanol synthesis component CuO/ZnO/Al2O3 and methanol dehydration component HZSM-5, which was prepared by coprecipitation and shaped by spray drying to get spherical particles. The effect of silica sol on the catalytic activity was investigated in a fixed-bed flow microreactor. Based on the experiment results, silica sol in the range of 0-20wt% had small effect on the catalytic activity. Generally, the CO conversion and DME yield decreased with the increase in concentration of silica sol, while the attrition resistance of catalysts increased with increasing silica sol, indicating that it was feasible to improve the attrition resistance without greatly sacrificing the activity of catalyst. In addition, the characterizations of catalysts were carried out using Brunauer-Emmett-Teller （BET）, X-ray powder diffraction （XRD） and temperature programmed reduction （TPR）.  相似文献
