An Analysis of Difficult-to-learn Materials in Science Curriculum for Grade Three to Grade Five Students in Elementary Schools Author: Tien-Ying Lee(Graduate Institute of Science Education, National Taiwan Normal University)

Abstract：

The purpose of this study is to find the possible reasons for the fact that students could not achieve as the curriculum is designed for. The congruence among intended, implemented, and achieved curriculum is investigated based on the Tyler's curriculum evaluation model. Test results from the project of "Evaluation of elementary school stu-dents' science achievement" from the Taiwan Provincial Teacher In-service Center dur-ing 1980-1986 are used and analyzed.
Findings indicate that there is 4 % of congruence among intended, implemented, and achieved curriculum. Low percentage of congruence, inadequate arrangement of learning materials, and complexity of answer form of some test items are the main rea-sons for students' low achievement.
Results reveal that there is not enough research data which are related to elemen-tary students' science learning. It is suggested that more practical oriented research could be done.
