Some discussions are made about practices which take places in some aspects of instructions from the viewpoints of traditional and reform based instruction. This kind of discussion is needed to be done, because there is no evidences to show that reform based instruction is mainly implemented among teachers even through reform based instruction has continued to be stressed since the 7th national curriculum was released. Some suggestions was made for consideration of further deep discussions based on the practices discussed earlier.

This study investigated the effects of cooperative and individual computer-assisted instructions upon middle school students' science conceptions, achievement, perception of learning environment, and motivation. The cooperative, individual, and traditional learning groups were selected from a middle school, and taught about the motion of molecule for 5 class hours. Data analyses indicated that the students with cooperative computer-assisted instruction scored significantly higher than those with traditional instruction in the tests of conceptual understanding, perception of learning environment and motivation. Better understanding of the cooperative learning group was also found in a retention test of conceptions. In addition, there were significant interactions between the instruction and the level of prior achievement in the tests of retention of conceptions and motivation. Educational implications are discussed.

In this study, the multimedia CAl program for chemical equilibrium in high school grade 3 was developed and the effect of CAl on achievement and attitude toward chemistry instruction and computer was investigated. Before instruction, the test of attitudes toward chemistry instruction and computer were administered, and the grade in the mid-term examination was obtained. These scores were used as covariates. Mid-term science score was used as blocking variable. For chemical equilibrium instruction, traditional and computer assisted instruction were used. After instruction, the achievement test and the test of attitudes toward science instruction and computer were administered. The results indicated that students in the treatment group achieved significantly better than those in the control group, but did not show improvement of attitude to chemistry instruction and computer compared to those in the control group. No significant interaction between the treatment and the level of students' prior achievement was found. Female achieved significantly better under CAl than under traditional instruction. In two subtests(understanding and application), treatment group achieved better in the subtest of application than control group. CAl had an effect on chemical equilibrium state (about reversibility) significantly. While female of the treatment group did not show more positive attitude toward both chemistry instruction and computer significantly than that of the control group, male showed more positive attitude significantly. Educational implications are discussed.

본 논문에서는 2015개정 교육과정에서 중학교 필수과목으로 지정된 정보교과에 플립러닝을 적용한 수업모형을 제안하고자 한다. 플립러닝은 전통적인 강의식 교수법을 뒤집은 수업모형으로 구성주의 관점에서 시작된 학생중심수업의 한계점을 개선하고 더욱 활발한 상호작용 중심 수업이 이루어지도록 하는 수업모형이다. 본 논문에서는 학생들의 학업성취 및 학습동기 향상에 긍정적인 영향을 미칠 수 있도록 수업모형을 설계하여 정보교과의 다양한 영역에서 사용가능한 플립러닝 설계 가이드라인을 제공하고자 한다.

The effect of Web-based project learning on the science achievement and attitude of middle school students was investigated. Four classes of 9th grade at a coed middle school were divided into control and experimental groups. Web-based project instruction in which students utilized the Web to interactively carry out their projects was put into practice with the experimental group, while traditional instruction was employed with the control group. Pre- and post-test achievement and attitude scores were estimated through an analysis of covariance. Web-based project instruction was seen to be more effective in enhancing students’ science achievement and attitude than traditional instruction. In particular, the former instruction was most useful for improving higher level students’ achievement and attitude among the higher, middle, and lower level students of both groups, based on their academic achievement. The effect of Web-based project may result in eradicating negative cognition about gender difference.

The purpose of this study was to investigate the effects of STS (Science, Technology and Society) instruction on 5th graders learning motivation and scientific attitudes, using ARCS (Attention, Relevance, Confidence, Satisfaction) strategies. A total of 53 fifth grade students were sampled from an elementary school, and were assigned to the experimental and the control groups. For four weeks, the experimental group was treated with STS instruction using ARCS strategies while the control group was treated with traditional instruction. The result of this study showed that STS instruction using ARCS strategies was more effective in the development of students' learning motivation and scientific attitudes.

purpose of this study was to examine the effect of Small-Scale Chemistry(below SSC) Lab Program on academic achievement and science-related affective domain of high school students. For this study, SSC Lab Program was developed on the basis of analyzing the chemistry part of the high school science textbook in the 7th curriculum. The experimental group was received SSC experiment lessons(below SSC group), and the comparison group was received traditional lessons. According to the result of this study, there was a significant difference (p<.01) between a SSC group and a comparison group in academic achievement. Also, there were significant differences in science-related affective domain, especially interest and scientific attitude. It showed that SSC Lab Program was more effective to improve the academic achievement and science-related affective domain. Student perceptions on SSC Lab Program were also discussed. Majority of students thought that SSC lab program was an effective and interesting way in science study.

Preconceptions of middle school students related to chemical change the students are surveyed. The students are divided into experimental group that are learned by concept change theory teaching model, and control group that are learned by traditional teaching method based on science textbooks. After the planned classes, the tendencies of concept change of the two groups according to students learning motivations are analyzed. New teaching methods, which based on concept change learning model and students learning motivations, developed by this research. And the effects of the new teaching method are testified. As a result, it is proved that most of the students have a lot of preconceptions, and persist the wrong conceptions after the classes. This tendency is same in the control group and in the experimental group.

The purpose of this study is to devise a Small-Scale Chemistry (SSC) lab program for primary school learners and to examine its effects on science learning achievement. In addition, it will be examined whether the type of learning groups affects the achievement or not. The participants in the current study were 173 6th graders from 6 classes of Y elementary school in Changwon city, Gyeongnam. Three classes(86) were assigned to the experimental group and the other three, the comparative group after checking the pre-homogeneity between the two groups through t-test on the scores of the science mid-term exam. We conducted five experimental sessions on the Acid and Base in the science textbook for the sixth graders. The students of one experimental class worked in pairs and another class worked individually, but the students of the comparative classes were divided into groups of six(one group with pair, another group with individual work in the SSC program, and the other group conducting the traditional experiment with groups of six students). The data were analyzed by t-test and ANOVA. The results showed that experimental learning using individual work in the SSC program compared to traditional experimental learning was effective in improving science learning achievement. also it was indicated that the teachers could reduce their burden of preparing for classes and of school hours when they utilized the SSC laboratory learning program. Teachers could also actively support students' experimental activities in employing the program. Based on the results, we suggest that the development of the SSC laboratory learning program is meaningful in the sense that this program can help elementary schoolers to improve science learning achievements more than the existing traditional experimental methods.
