최행숙,김은경,백성혜,이길재,정완호 한국교원대학교 과학교육연구소 2001 청람과학교육연구논총 Vol.11 No.1
In this study, the contents of elementary school science textbooks related to 'heat and temperature' are analyzed and alternative conceptions of "heat and temperature" among students enrolled in grades 4, 5 and 6 are investigated. 259 students were selected from a elementary school located in urban area. The relationships between students' alternative conceptions and the content of elementary science textbooks are also examined. Students' conceptions are analyzed from their answers to a paper-and-pencil test. The typical alternative conception of "heat and temperature" held by students was follows. They think that "heat" is a material and "temperature" is value of heat amount. They can't distinguish between "heat" and "temperature". Their explanation of "heat and temperature" is focused on hot or cool sensation and other observable characteristics of a material. A textbook analysis indicated that contents on "heat and temperature" were organized without the viewpoint of particle motion theory. This may be one of the causes of students' alternative conceptions.

초등학교 과학실험 기구 조작 기능에 대한 관찰 평가 준거 개발 : 초등학교 화학 단원을 중심으로
최행숙,백성혜 한국교원대학교 과학교육연구소 1999 청람과학교육연구논총 Vol.9 No.1
The purpose of this study is the development of the observation Assessment criteria that is used to assess manipulative skills in elementary science. The procedures of developing observation Assessment criteria are as follows. First, we investigated the actual condition about science process skills assessment with the questionnaire. Second, we selected 7 experimental apparatus through the analysis of the science textbooks. The selected experimental apparatus are dropper, alcohol lamp, thermometer, test tube, filtering device, table balance, graduated cylinder. Third, the observation Assessment criteria are developed through the analysis of the related experimental textbooks, the demonstrations, and the questionnaire. Forth, the validity is verified by science education specialists and graduate students who major in science education. Fifth, the first inter-rater agreement is investigated in the result of the field with observation criteria of which the validity was verified. The second inter-rater agreement is investigated through the revision and the addition of the criteria with the low agreement. In result, the inter-rater agreement ranged from 0.86 to 0.98. One of the major problems in observation assessment is the rater's subjective viewpoint. So, this research shows a more specified scale and criteria for the assessment. This suggests that the observation Assessment criteria developed in the study satisfies the high reliability and validity requirements. Considering the results, this criteria can be used effectively for assessing manipulative skills of elementary school students.
