This study investigated the influences of applying the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy: Kwon, 1989) upon students' achievement and attitudes in a middle school science concept instruction. For the treatment group, science instruction to apply the Cognitive Conflict Process Model was used. For the control group, traditional instruction was used. Prior to instruction, students' pre-conceptions test and attitudes test related to the science were administered. After instruction, the above two tests and the regular examinations were measured. Also students' perceptions of their teacher's new teaching style was investigated by questionnaire. But, above all, the main purpose of this study was to investigate the principal accompanying matters of general application of the teaching model to science concept instruction rather than conceptual and attitudinal change. Therefore, this study identified necessary conditions of applying the teaching model to science instruction.

Recently there has been increasing emphasis on pedagogical content knowledge (PCK) for fostering science teachers' teaching professionalism that needs to be done from teacher training courses systematically. We investigated what were the PCK factors considered in planning instruction and the difficulties encountered in implementing it by pre-service teachers. In this study, 26 sophomores at an university of education in Gyeonggi province were asked to perform teaching demonstrations using scientific instruction models. They were also requested to write reflective journals and interview. Analyses of the results revealed that many pre-service teachers considered the teaching strategies such as the instruction organization and implementation when planning instruction. They had also regard to the learners' cognitive affective aspects, whereas the pre-knowledge of them was not properly considered. Especially, the curriculum and assessment were almost disregarded. Most of the difficulties encountered in planning instruction and implementing it were appeared in terms of the teaching strategies. For example, they had difficulties in considering the characteristics of each stage presented by the instruction models when planning instruction and implementing it. The frequencies of the difficulties in implementing experiment were especially higher than those of the other PCK factors. Educational implications of these findings are discussed.

This study is aimed at exploring the effects on Science Inquiry Ability, Scientific Attitude and Science Achievement of the Elementary School Students according to the Input time of Web-Based Instruction Programs. As the object of the study, seventy-two students were selected from three classes in the fifth grade of Y Elementary School located in the city of T, Gyungsangnam-do. They were classified into the three groups such as Group A (Class 1), Group B (Class 2) and Group C (Class 3). The author threw web-based instruction programs into the begining of a unit, during a unit, the end of a unit to each group, and explored the effects. The results of this study were as follows: First, for the learning effect of science inquiry ability, it was indicated that there was the highest effect in the case of throwing web-based instruction programs into during a unit, but the effect reduced a little in the case of throwing them into the end of a unit. Secondly, the scientific attitudes tended to be reduced in the case of throwing them into during a unit, but there did not occur statistically significant improvement. Thirdly, the degree of improvement of the science achievement tended to be highest in the case of throwing them into the end of a unit. Such findings indicated that the time of throwing in web-based instruction programs affected science inquiry ability, scientific attitude and science achievement of elementary school students. Thus, it will be said that teachers need to teach their students with the class strategies of considering various scientific elements revealed at the time of throwing in web-based instruction programs.

The purpose of this study was to analyze the types of teachers' questioning between verification laboratory instruction and discovery laboratory instruction. Results were that there was no difference in questioning types in verification laboratory instruction and discovery laboratory instruction. Most teachers in two types of laboratory instruction used closed questionings more than open-ended questioning. This shows that teachers' laboratory instruction processes are focusing on 'get the content' rather than consideration of the characteristics of laboratory instruction types. Such results show that the teachers in verification laboratory instruction and discovery laboratory instruction provide little opportunity for children to improve in scientific thinking. Therefore, teachers should make good plans with a questioning strategy that can be adapted to the types and characteristic of laboratory instruction. If teacher's questioning is practiced well in the science class, it can improve students' scientific thinking and science laboratory instruction.

In this paper, I studied on reading instruction in the school library. Reading instruction is a very important role of school library. And it is an essential element of school education. In this paper, I tried an application of constructivism for reading instruction. Information literacy instruction of school library includes reading instruction. So the pattern of information literacy instruction of school library was accepted as reading instruction pattern of school library in this paper. And then constructivism for learning principle and reading strategies as reading instruction was analyzed in this paper. Gerard J. Westhoff categorized reading strategies into 4 parts. I applied this categorization of reading strategies to the reading instruction pattern. And I analyzed and synthesized these relative constructivism elements and reading strategies for the reading instruction pattern in this paper.
