核心素养理念下的化学实验教学策略探究

新课程标准已经明确指出,实验在初中化学教学中占有重要地位。教师在初中化学实验教学中,要努力创新实验教学方式,激发学生的化学探究兴趣,提高学生的实验探究能力和动手操作能力,培养学生的化学核心素养。文章对核心素养理念下的初中化学实验教学进行分析,并提出几种教学策略。

The Application of an Adaptive Web-Based Learning Environment on Oxidation–Reduction Reactions

The World Wide Web is increasingly being used as a vehicle for flexible learning, where learning is seen to be free from time, geographical, and participation constraints. In addition to flexibility, the Web facilitates student-centered approaches, creating a motivating and active learning environment. The purpose of this study is to set up an adaptive learning environment on Internet and to experiment with the most suitable methods and applications. Our goal is to provide a better solution with regard to the related distance learning research. All the resources and background are from current relevant documents on the theory of asynchronous distance education. We set up an adaptive Internet learning system based on learning theory and related learning models. Our research targets are those students who took the ‘Life Chemistry’ course for the asynchronous distance education environment at Providence University at Taiwan. The students were divided randomly into two groups: the experimental group, which was in an adaptive learning environment and the controlled group, which was in a non-adaptive one. We used the American Chemistry Society Test Bank as our research tool and used SPSS to analyse the data we obtained. Results show that the experimental group in the adaptive learning environment out-performs the controlled group. In addition, those students who are field independent learning types, have higher pre-knowledge, are male, in science departments and have a longer study time span in an adaptive learning environment show much greater achievement levels than those in the opposite situations.
