The purpose of this study was to examine the effects of animation-based instruction on elementary students' level of understanding and interest on a plant's structure and function, using "Magic School Bus(Joanna Cole, Bruce Degen, 1986)". The understanding and interest measurements were administered to 99 fifth grade students at a elementary school located in Seoul. The study examined the changes in understanding and interest through pre-test and post-test of the two groups. Intensive interviews were conducted to find factors that enhance understanding and interest. Three key findings were revealed from the results. First, the animation-based instruction enhanced the level of understanding in the experimental group compared to the control group. Second, animation-based instruction made high-achieving students enhance their interest in topic component and attitude component. And, animation-based instruction did not led low-achieving students to increase their interest in the topic component and attitude component. We suggest that animation-based instruction positively influences students' understanding, but its effects on students' interest are dependent on their conceptual understanding of the topic.

Various data and methods are necessary to help students understand the science subject, and have interest in it. Most students like cartoons, and more easily memorize their contents. The purpose of this study was to verify the effects of science cartoon reading on the academic achiements, the levels of interests in science and scientific attitudes of elementary students The study subjects were four classes of the 6th grade of G elementary school in U city. Two classes were experimental group and the others were comparison group. The students of the experimental classes were encouraged to read science cartoon related to class contents at the beginning and ending for 5 minutes respectively in instructional time. And those of the comparison classes received general science lesson. The results of this study were as follows. First, the experimental classes encouraged to read science cartoon marked higher average score than comparison classes in post-test and the difference was meaningful (p<.05). This meant science cartoon reading treatment had the effect of improvement of the levels of interest in science of student. Second, the experimental classes marked higher average score than comparison classes in post-test but didn't show meaningful difference. This meant science cartoon reading treatment didn't have the effect of improvement of academic achievement of students in our study. Third, the experimental classes marked higher average score than comparison classes in post-test and showed the meaningful difference(p<.05). This meant science cartoon reading treatment had the effect of improvement of scientific attitudes of students. From the results thus far, we could tell that science cartoon reading had positive effects on the levels of interest in science and scientific attitudes of students in our study.

The purpose of this study is to analyze the concept concerned with Earth's rotation as passed by tenth graders whose interest in earth's rotation and learning styles were varied. To examine student's interest in the Earth's rotation, 4students (visual-verbal learning style student with much interest, visual learning style student with much interest, visual learning style student with little interest, and verbal learning style student with little interest) were chosen for study. Personal interview was used for this study. To probe students' conception in varied ways, they were allowed to make gesture and draw pictures through data collection process, except for interviews. And the data were analyzed one by one. The result of this study were as follows: First, the student with much interest was faster to answer the questions about Earth's rotation than the one with little interest. Also he comprehended better and was able to explain reasons coherently. Second, there was little difference according to student's learning style. Third, one of the repeated misconception was direction. For thinking that is the right side is the east side, students have misconception that the sun goes from right to left and stars in north sky move clock-wise.

The purpose of this study was to investigate the effects of science toy making activities on the scientific interest and the conceptual understanding of elementary school students. In this study, science toy making activities were applied to an experimental group and traditional learning activities were applied to the control group. The science toy making activities comprised thirteen steps and were administered during class. In the scientific interest test, there was a statistically significant difference between the score of the experimental group and that of the control group. In particular, post-test scores were higher than pre-test scores in the experimental group, while they were lower than this in the control group. It appeared that students had positive thoughts about science toy making activities. These science toy making activities had positive effects on the conceptual understanding of the experimental group students. The post-test scores of the experimental group were higher than that of the control group in all domain concepts. From these results, it can be deduced that the science toy making activities were more effective than traditional teaming activities. They were an effective teaching technique which enhanced the scientific interests and the conceptual understanding of the students in question.

The purpose of this paper is to present a neural network model based on change-point detection for the prediction of the U.S. Treasury Securities. Interest rates have been studied by a number of researchers since they strongly affect other economic and financial parameters. Contrary to other chaotic financial data, the movement of interest rates has a series of change points due to the monetary policy of the U.S. government. The basic concept of this proposed model is to obtain intervals divided by change points, to identify them as change-point groups, and to use them in interest rates forecasting. The proposed model consists of three stages. The first stage is to detect successive change points in the interest rates dataset. The second stage is to forecast the change-point group with the backpropagation neural network (BPN). The final stage is to forecast the output with BPN. This study then examines the predictability of the integrated neural network model for interest rates forecasting using change-point detection.
