A Study of Learning Behavioral Engagement in Live Teaching     

LIU Sizhuo  LI Shuang  HUANG Jiajing 《Frontiers of Education in China》2022,17(1):69

Based on the related theories and research results of learning behavioral engagement, this study constructed an evaluation framework of learning behavioral engagement in live teaching, which included 24 indicators in three dimensions: compliance with norms, learning participation and social participation. A small-class live English learning for younger students on the ClassIn was taken as a case study program. Five younger students attended this English learning course of 16 lessons totaling 950 minutes. The preset indicators were preliminarily examined based on the teaching records and the recorded course data. Then, experts in the field of educational technology were invited to develop the learning behavioral engagement dimensions and indicator weightings by using the Analytic Hierarchy Process, and to determine the evaluation indicator system for the evaluation of learning behavioral engagement. Finally, based on this framework, the characteristics of learning behavioral engagement of the case course were analyzed, and the influences of students’ individual factors, teaching and environmental factors on learning behavioral engagement in live teaching were investigated.  相似文献

The Effect on Enhancing Students＇ Inquiry Abilities via Step-by-Step Open-ended Inquiry Teaching Design     

Chung-Ming Yang  ;Jeng-Fung Hung  ;Tai-Chu Huang 《美中教育评论》2014,(12):887-894

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel＇s proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification （from levels of inquiry 0 to 2b） and to combine the experimental teaching method with the 5E （engage, explore, explain, elaborate, and evaluate） learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders＇ basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the ＂predicting＂ dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on ＂interpreting data＂ as well as ＂experiment designing＂ dimensions. Hence, the study indicated that it could enhance students＇ inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.  相似文献
