基于马克思主义实践观的学习双机制理论对现代教育教学的启示---莫雷教授学习心理学创新研究探索40年

我国著名发展与教育心理学家莫雷教授经过长达40年的深耕探索,提出了基于马克思主义实践观的学习双机制理论。这一理论对于认识人类的知识学习与能力发展的客观规律,理解皮亚杰、布鲁纳、奥苏贝尔等著名教育家的观点,把握减负、大概念、PBL教学、素养导向、真实情境活动等当前教育教学改革的趋势,以及对于指导学前教育科学发展、基础教育创新能力培养等重大教育实践问题,都有着非常重要而深刻的启示。

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

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.
