| Summary: | 碩士 === 國立台中師範學院 === 自然科學教育學系 === 89 === This research undertook a general survey about the concepts regarding atom, molecule and particle among the primary school pupils around Taiwan. The purposes were firstly to develop a reliable and validated concept instrument to investigate primary pupils'' understanding and misconceptions of the above concepts. In-depth interviews had been undertaken to explore what are held in pupils'' cognitive constructions. The ultimate goal is to provide detailed mechanism of primary pupils'' conceptual understanding profiles in Taiwan so that they may be helpful to the curriculum designers and textbook writers.
Concepts regarding atom, molecule and particle play a vital role in many fields of primary school science, however, most pupils have suffered great difficulties in this aspect. A pilot study had been conducted with a sample of 754 primary school pupils using reliable and validated concept instruments. The structured interviews with the 78 selected subjects was subsequently held and used to support the need to direct an individual''s attention to specific features.
Based upon the results from questionnaires and interviews with sample students, the main findings are listed as following:
(A) No significant differences are found in the misconceptions about particles held among pupils from different areas or between pupils of different genders.
(B) There are significant differences among the response types of pupils when three kinds of questionnaires were administered to them.
(C) The main types of particle conceptions and misconceptions held by the primary students can be classified into four categories:
a. Misconceptions about particles that construct matter.
b. Misconceptions about particles that construct the same matter in different states.
c. Misconceptions about particles that construct the matter during phase change process.
d. Misconceptions about the scientific terms and daily language used to illustrate particles that construct the matter.
