Recently substantial learning model is strongly demanded through which ICT could be effectively used at PBL, teaching and learning method, based on constructivism putting an emphasis on learner centered education. This thesis is designed to introduce the way to make the most of ICT when teachers try to make teaching plan applying PBL to science class. PBL courseware is designed to make teacher and student use by applying traditional science class model to the model for problem solving of PBL. analysing class according to the degree of connecting ICT with contents of learning. This paper suggests 8 stages of PBL package development and 5 stages of teaching pattern to grasp whole procedure.

In this study, Jigsaw III cooperative learning strategy and traditional learning strategy have been applied to the 'electricity' chapter of grade 8 science textbooks to know the effects of learning strategy, gender, and GPA on the students' science achievement and science learning attitude of middle school female students in gender-separated classes. For this purpose, 143 students of 4 classes in separated classes were chosen from a middle school in Daegu. One female class and one male class were assigned to the experimental group and other female class and male class were assigned to the control group. Traditional learning strategy was applied to the control group and the Jigsaw III cooperative learning strategy was applied to the experimental group. Four worksheets for expert groups were used for 18 hours through 5 weeks. Both tests for science achievement and learning attitude were administered as pre and post test. The test results were analyzed through analysis of covariance(ANCOVA) as pre test score as covariant The overall conclusions of this study were as follows: The Jigsaw III cooperative learning has improved science achievement, especially on subjective-type questions, of female students and mid-lower level students. The Jigsaw III Cooperative Learning has also improved self-directed attitude toward science learning. Female students have expressed more positive opinion about the Jigsaw III cooperative learning.

This research was conducted with an intention to develop a teaching program that possesses a goal of elevating higher thinking ability within the science class and to investigate its effect. The hypothetico-deductive teaching model was developed and its' program was designed to be directly put into the practical use, and apply it in class. The application of the hypothetico-deductive teaching program had a positive effect in the improvement of students' creative thinking ability and critical thinking ability. And it had a positive influence on scientific attitudes. After completing the program the opinions of the students who participated in this research by a poll were gathered and analyzed. The students felt uneasy and had a lot of difficulties during the program activity because they had to keep on thinking newly, critically, and scientifically, but they admitted that they gained the ability to think on their own when the program was completed.

This research was aimed to develop and apply the molecular genetics teaching program based on the history of science and creative problem solving model (HS-CPS model) for gifted students. Based on the strategies of creative problem solving and scientific theory development, the HS-CPS teaching program were developed. This program was applied to 8 first and second graders of the special class for invention activity in a high school. Creative problem solving ability in science and the understanding of DNA and gene concept were tested in pre and post of 12 lessons. The results were as follows: First, creative problem solving ability in science was improved meaningfully. Second, HS-CPS teaching program was effective in the understanding of DNA and gene concepts. Third, the students responded positively to the program evaluation questionnaire.

Circular motion has been one of the most difficult concepts for students to understand. To facilitate for students to form scientific mental models about circular motion, this study developed 4M learning cycle teaching model based on the integrated mental model theory and strategies. For this study, fifty-three eleventh graders at a technical high school in Inchon were taught for 3 class hours. We conducted tests of basic physics concept and mental model of circular motion before, after, and two months after instruction. In results, we found that there were statistically significant improvement in the test of basic physics concept and mental model related with circular motion after instruction. Especially, this teaching model affected learning effectiveness of Correctness and Coherence of mental model.

Inquiring earth science phenomena is characterized by the followings: a big scale of time and space, inaccessibility, uncontrollability, and complexity. Thus, it is very difficult or, in some cases, impossible to investigate them through the actual manipulation in laboratories. Therefore, it is necessary to provide chance for students to experience scientific inquiry without actual manipulation in earth science classes. This study is to explore the role of reasoning based on a thought experiment as a representative model without actual manipulation, and to investigate features of various inquiry models using reasoning in classes. We can make implications when applying for applying each inquiry model to earth science classes, proposing a reasoning-based inquiry model embedded in earth scientific phenomena.

This study aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.

Although many studies have investigated the effectiveness of concept mapping and the learning cycle, in Korea none have explored the effectiveness of concept mapping and the learning cycle combined. This study explored the effectiveness of concept mapping, the learning cycle, and a combination of concept mapping/learning cycle(CL) in high school biology class. Students' science achievement, the science related attitudes and scientific inquiry ability was measured. The results indicated that concept mapping, the learning cycle, and CL treatment were significantly different from the traditional one in science achievement(p< .05). However, the three treatments were not significantly different from each other. No significant difference exists among different learnings in high and average-ability students. But, concept mapping was the most effective in low-ability students. For the students' scientific inquiry ability, CL and learning cycle were more effective than concept mapping and traditional learning. No significant difference exists among different learnings in high-ability students. CL and learning cycle were more effective than concept mapping and traditional learning in average and low-ability students. For the students' science related attitudes, concept mapping, the learning cycle, and CL were more effective than the traditional learning. But, there was no significant difference among these three groups.
