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.     

双语评价：Look before you leap

双语教育评价是双语课程改革的核心内容。要搞好双语课程实验，必须做到“评价先行”。正因为评价的导向作用，在实际操作中更应该“三思而行”。要搞好双语教育评价，让评价的功能实现从“棍子”、“鞭子”到“尺子”、“旗子”的转变，就要解决“为什么”、“什么”和“怎么”的问题，找到简单易行、科学有效的评价办法。“作业式评价”就是好的评价办法之一。它是集模糊评价、整体评价、定性评价、发展性评价于一身的简单的评价方式。

从教学过程设计转向信息技术支持的学习环境设计

由于中美两国历史文化背景的差异,在学科演化和发展上也呈现不同的道路,引进的教学设计在中国遭到了已有的"教学论"的质疑。对教学设计的概念重新进行梳理后,重新解读了中国的"教学设计"的内涵,以期能抛砖引玉,促进教学设计在中国的健康发展。     

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.
