原位固化法高效合成ZnO/环氧树脂纳米复合材料

ZnO纳米颗粒可以明显提高固化后环氧树脂的性能.本研究制备了ZnO量子点/环氧树脂复合材料,环氧树脂使用聚酰胺固化剂,在低温下短时间固化.合成过程中,使用正己烷取代丙酮作为溶剂,从而提高复合材料的机械性能.随后,使用紫外-可见透过光谱、荧光发射光谱和硬度等研究了不同制备工艺下ZnO/环氧树脂复合材料的光学性能和机械性能.结果表明,通过原位固化法将ZnO量子点与聚酰胺固化剂混合得到复合固化剂,将树脂与该固化剂混合后,可以在低温下固化得到具有较好机械性能和光学性能的ZnO/环氧树脂纳米复合材料.     

Do students learn what they teach when generating teaching materials for others? A meta-analysis through the lens of learning by teaching

Students can generate teaching materials for others. However, solid evidence of the learning effect for the student creating the material is needed. This meta-analysis aims to explore current evidence of the learning-by-teaching potential effect on students’ learning of the content they teach. A total of 23 articles were included in the meta-analysis, providing 62 comparisons between an intervention in which students were required to create a teaching material and an alternative condition. Possible moderators were examined as well (i.e., product, educational level, content area, and access to source material). Results show statistically significant differences in favour of creating teaching materials when compared to business-as-usual or alternative interventions, with an overall effect of 0.17. However, the type of product and the access to source material significantly moderate the findings. Audio-visual and visual materials considerably outperform textual materials. Having no access to the source material is better than having full access to it. No publication bias was detected. However, the type of control group moderates the findings: creating teaching materials shows a significant effect when compared to nonbeneficial interventions rather than to other expected beneficial interventions. Nonbeneficial interventions refer to business-as-usual or alternative interventions that are not expected to influence the outcome much, while beneficial interventions are those that are known or expected to have a positive effect. The findings are discussed based on the different views on the underlying learning-by-teaching mechanisms. Limitations as well as implications for practice, policy, and future research are underlined.     

师范高等专科学校物理专业“理论力学”课的教学探讨

《张治中回忆录》及其史料价值

《张治中回忆录》是张治中在生前留下的一份自述。它由张治中和余湛邦共同撰写,三易其稿,历时十年而成,不仅详细记述了张治中过去六十年在政治、军事和教育等方面的种种活动,生动地展现了他为国为民而奋斗的一生,而且还保留了丰富的原始档案材料,具有重要的史料价值,对于学术界深入研究张治中的各种思想、抗战初期湖南的社会状况、新疆的和平解放、国共关系的发展以及两次淞沪抗战等有要作用。但同时受主客观因素的影响,该书也不可避免地带有一定的局限性。
