The purpose of this study is to construct a structural equation model and to analyze causal relationships among variables related to attitudes to science using structural equation modeling(SEM) with LISREL VII. The sample consisted of 483 10th grade boys from a general high school in Pusan, Korea. The questionnaires (ABC-attitude scale: affection, behavioral intention, cognition scale of attitude towards science) were developed by the researcher through a pilot study. And other instruments have modified previous ones. Five instruments were used in this study: GALT(group assessment of logical thinking), MTSlS(modified test of science inquiry skill), ABC-attitude scale, MSAS(modified scientific attitude scale), CSAT(common science achievement test). Structural equation modeling with LISREL VII($J\ddot{o}reskog$ & $S\ddot{o}rbom,$ 1993) was employed to estimate the causal inferences about hypothesized relationships among observed data sets. Three competing models consisted of five latent variable(scientific thinking ability, science inquiry skill, attitude towards science, scientific attitude, science achievement) - lP(inquiry preceding) model, AP(attitude preceding) model and AM(attitude mediating) model - were developed. Among these competing models, IP model satisfied the observed data sets. The causal relationships among "attitudes to science" and other latent variables were reliably identified. According to the results of the present study, science inquiry skill was the most significant variable that can predict science achievement. But scientific thinking ability has not directly influenced science achievement. This study suggests that inquiry based teaching-learning processes should be offered to students for improvement of science achievement. At the same time, it seems to be important to develop positive attitude towards science. Understanding of relationships among variables related to attitudes to science will be helpful to the development of science curriculum and to the design of science teaching and learning process. LISREL has been recognized as a useful approach in testing a SEM. However, in this study, LISREL approach was estimated as much more useful method for research design.

The purpose of this study was to evaluate the effects of STS Programs on science-related attitude of junior high school students. For this study, samples of 198 students who are in grade 8 were selected. The eight STS Programs were used in this study. One group pretest-posttest design was used in this study as an experimental design. The TOSRA was used in this study as the science-related attitude evaluation instrument. The major results of this study are as followings: 1. The effects of STS programs about the junior high school students' science-related attitude indicated that there were no statistically significant differences between pretest and posttest. 2. Total students were classified as high(above about mean) or low (bellow about mean) on the basis of science-related attitude pretest scores. The low level students have improved from using of STS programs in teaching science on science-related attitude scores. The high level students have dropped from using of STS programs in teaching science on science-related attitude scores.

The purpose of this study was to identify the effectiveness of science writing on organizing scientific knowledge and improving science process skills and science attitude, as science educators have indicated. For this study, two classes of $5^{th}$ grade students were chosen in the same elementary school. Subjects were divided into an experimental and a control group. The students in the experimental group took part in a science writing program for 14 lessons of science classes. The students in the control group were taught according to the traditional science program using standard science textbooks. To identify the effects of science writing, both groups' students were tested on science achievement, science process skills, and science attitude before the program implementation and were tested on science concept, science process skills, science attitude after the program implementation. The results of this study showed that the experimental group gains significantly higher scores than the control group in science concept and science attitude, but there was no significant difference on science process skills for either group. In conclusion, science writing had positive effects on science concept and science attitude of elementary school students, helping them to express their thinking logically and systematically, but science process skills were not affected.

The Purpose of this study is searching the effect of the flow level increasing by using flow learning on scientific achievement and attitude toward science in 4rd grade elementary school student's scientific learning factors, and the better way to approach scientific institude than now in used. Participants included 52 elementary school students. For this study, two classes were divided into experimental class and control class. The control class takes a regular instructions and the experimental class takes a flow learning instructions. Two chapter were selected, 'Plant's World' and 'Fossil and Rock', for this study. Students were treated for 18 hours. The results were as follows: First, flow learning related program about plant's world, fossil and rock is increasing 4rd grade elementary school students' flow level in science class. Second, students are not increasing their scientific achievement according to increasing their flow level. Third, students are not increasing their attitude toward science according to increasing their flow level. But in attitude toward scientific inquiry, adoption of attitude toward science and preference of job related science subordinated, students are increasing subordinate factors of attitude toward science.

This study was undertaken to investigate the general attitude toward science and scientific inquiry behavior of underachiever at the junior high school level. In this study, underachiever was defined as the one who is below the minimum acceptable performance level because of his/her deficiencies in prerequisites but who has the capability to reach the required mastery level in normal classroom. For the identification of the underachiever, IQ test and achievement test in science which were developed by the investigators were used. The attitude test which was to measure the general attitude toward science and scientific inquiry behaviors of the underachiever was also developed by the investigators. The tests were given to 250 1st grade junior high school students in one experimental school. Out of 250, 55 underachievers were identified. For the study, 55 underachievers with 57 normal students were compared. The findings of this study showed that there were significant differencies between underachievers and normal students in both attitude toward science and scientific inquiry behavior. They can be summarized as follows; 1. Awareness on science by underachievers was minimal compared to normal students. 2. Compared to normal students, there was a tendency by underachievers to think the influence of science on their real life is remote. 3. Underaschievers were less positive, less voluntary and were less persistent in science activities than normal students. 4. Underachievers were less interested in science than normal students. These findings showed us that there were significant relation between the attitude and achievement level. This suggests that fostering attitude toward science and scientific inquiry behavior is needed for the improvement of achievement level of underachievers.

The purpose of this study was to identify the effect of mind map activity on scientific attitude and science achievement in elementary school science. The subjects of this study were fifth-grade students selected from two classes in elementary school located in Seoul. The subjects were classified into two groups: One group is composed of thirty-eight students(experimental group) who were participated in mind map activity, and the other is composed of thirty-five students(control group) who were participated in traditional teaching situation. Pretest showed that there were no significant differences between experimental and control group in scientific attitude and science achievement. The results were as follows: First, the experimental group showed a significant improvement in the post-test science achievement compared to the control group. Second, the experimental group showed insignificant improvement in the post-test scientific attitude compared to the control group. Third, female students and mid-ranking group showed a significant improvement in the post-test science achievement. Fourth, in sex and academic ranking, experimental group did not show significant difference in the post-test scientific attitude. In conclusion, mind map activity was more effective than traditional teaching situation on science achievement. But mind map activity was less uneffective than traditional teaching situation on scientific attitude.

The purpose of this study is to analyze elementary school students' personality, scientific attitude and to find the correlation between elementary school students' personality and scientific attitude. To determine this, the distribution of sixth graders' personality and scientific attitude was examined and correlation between the lower categories of each one was analyzed. The test tools and the subject were decided through the two preliminary examination, personality test and scientific attitude test were investigated appling to a total of 354 sixth-grade students at eight elementary schools in this study. The test results were analyzed with averages, standard deviations, correlations, ANOVA using SPSS/PC/sup +/. The major results of analysis are as follows. First, the distribution of scientific attitude proved that the average of boys' curiosity was higher than that of girls' curiosity, but girls' average was higher than boys' average in criticalness property, cooperation property, preparation property, continuation property and patience property. The distribution of upper group and lower group in personality properties revealed that the ratio of upper group was higher than that of lower group in activity property, social property, but the ratio of lower group was higher than that of upper group in responsibility and reflective property. Second, the socio-populational variables affecting 6th graders' personality' and science attitude were a sex, a sibling order. The cognition variables affecting 6th graders' personality and science attitude were preference, extent of usability to practical life and interest of science. Third, analyzing the correlation between lower categories of personality and lower categories of science attitude revealed that activity property of personality rather highly correlated to willingness property, critical property at .399(p<.01), .351(p<.01) respectively. and that consideration property of personality highly correlated to curiosity, critical property at .451 (p<.01), .415(p<.01) respectively.

The importance of science attitudes is more increasing in science education. Science attitudes may influence students' attainment, consistency and quality of classwork as well as their later views of science education and scientific occupations. According to the international comparative researches and longitudinal studies on Korean students' science attitudes, it has shown that the more grade, the less science attitude. This research was survey the science attitudes and learning environment variables, and then make a inquiry that causes of decline of science attitudes. To study this purpose, the participating students in this study will be selected from 3th to 11th grade. 6,925 participants were administered 3 times in questionnaires of science attitudes and learning environment variables during a year. The result of this study showed that science attitude got low after June. Science attitude was changed from 4th grade to 8th grade students. Science attitude much more decrease second semester than first semester, high school students' science attitude fell much. It was experience about science that cause the biggest effect in science attitude and other learning environment variables influence in science attitude change. Learning environment variables made different influence from students of increased and declined science attitude. As category that influence in science attitude, in elementary school were gender, area and grade, in middle school were grade and area, and in high school was area.

The ARS(Attitude Reference System) calculates an attitude of a vehicle using inertial angular rate sensors and acceleration sensors. The attitude error of ARS increases due to the integration of angular rate sensor output. To reduce the attitude error an acceleration of sensor is used similar to leveling method of INS(Inertial Navigation System). When an acceleration of vehicle is increased, it is difficult to calculate the attitude error using acceleration sensor output. In this paper the estimation method of acceleration due to the attitude error only is proposed. Two methods of the attitude calculation depending on vehicle dynamics and the integration method of these two methods are proposed. To verify its performance the monte carlo simulation is performed and shows that it bounds attitude error of ARS to reasonable level.

The purpose of present study is to examine the science attitude level of middle school, high school and university students, and to provide the suggestions for science education. Instrument to invent science attitude consists of four domains as 'Scientific Inquiry', 'Importance of Contribution to Science', 'Normality of Scientist', and 'Social Value of Science'. Inventory instrument have 20 items(Likert scale of 1 to 5). Subjects are 70 middle school, 72 high school, and 95 university students. There is no significant difference among students by school, but the attitude level toward science of female students is lower than that of male students. 'Importance of Contribution to Science' among four domains has the highest score of attitude toward science, whereas 'Normality of Scientist' has the lowest attitude score toward science. To bring up scientific abilities of students, we conclude that it needs the educational plan to increase science attitude of students, through improving and developing curricular system and science curriculum for the secondary school and university.
