The Effect of 'Self Control Management Strategy' on the Reinforcement of Internal Locus of Control
Park, Jin-Hee ; Chang, Nam-Kee ;
Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 347~358
Locus of Control of Reinforcement (LOCR)' is considered as one of the most important factors on responsible environmental behaviors(REB). It is defined as 'an individual's perception of his or her ability to bring about change through his or her behavior'. This psychological construct is divided up into two directions: the external locus and internal locus. The internal locus is important as a predictor of REB. Recently, 'The Environmental Action Internal Control Index: EAICI' has been developed and it is a valid and reliable instrument to measure the relationship of two variables. The purposes of this study were to develop a strategy to reinforce the internal locus or to converse external locus to internal locus. and to verify the effects by EAICI. A new strategy, 'Self Control Management Strategy' was based on the characteristics of internal locus and the key idea of this was to self-control and to manage the courses by themselves. EAICI scores of the control group was 99.83. All of them were internal and the LOCR of females was more internal than that of the males. This strategy was applied when the instructions were carried out on seven environmental issues by the experimental group. According to the results. the seven points of the EAICI were increased significantly. Therefore this strategy is helpful in reinforcing the internal locus or to converse external locus to the internal locus.

The purpose of this investigation was to examine and compare pre-service and in-service secondary tearchers' beliefs about STS, particulary beliefs about the nature of science and technology and their interaction within society. For this study, a belief was defined as something that people believe and accept as true. Instrument used in this investigation was empirically developed multiple-choice instrument entitled the Tearchers' Belief about Science - Technology - Society(TBA-STS) by Peter A. Rubba and William L. Harkness. The result of survey showed that large percentages of the preservice and in-service secondary science teachers in the two samples held misconception about the nature of science and technology and their interactions within society. And there was no apparent difference between the samples on their beliefs about STS interactions.

Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 373~381
To investigate the preconceptions on the reference frame and relativity of motion, 251 of grade 7 pupils were selected. The questionnaire has 15 questions consisted of four test domains made by the researchers: object looks rest or moving in the rest frame, object looks rest or moving in the moving frame. The result shows that pupils took the observations in the moving frame for those in the rest frame, or vice versa. In addition, their answers varied according as the context of the observation differed.
The Effect of Force and Motion Conceptions into the Kinematics Graph Construction
Kwon, Sung-Gi ;
Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 383~393
In order to study the effect of student's conceptions about force and motion into the graph construction in kinematics in college physics course, the tasks of constructing the qualitative graph in the similar problem context used in force conception was asked to the first 74 and third 97 student teacher in teachers' university. The frequencies analysis showed that student teachers had the naive conceptions that the throwing force was still acted to a upwarding ball. They also had the popular Aristotelian views about motion. These naive conceptions coexisted with the scientific conception about gravitational force. In a simple pendulum problem no one had the correct acceleration concepts which varies the direction in swing. This result suggest that student teacher had more difficulties in a acceleration problem than in a velocity problem In v-t and a-t graph construction tasks, the number of categories of a-t graphs were more than that of v-t graphs. There were many graph errors in a sign of velocity and acceleration. The acceleration conceptions without the relations of changes in velocity made the kinematics graphs more various shapes. The force and motion conceptions influenced the ability to construct the kinematics graphs.

Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 395~403
In order to study the effect of the 'General Science' course implemented under the 6th science curriculum, high school students' views about the relationship between science/technology and society and their perceptions of science classroom environment were investigated. Four classes (n = 211) were selected from those completed the 'Science I' course under the 5th science curriculum, and 4 another classes (n = 216) which took the 'General Science' course under the 6th science curriculum were selected. In order to compare students' views about the relationship between science /technology and society. 10 items were selected from the VOSTS (Views On Science-Technology-Society) while considering the 6th science curriculum and the 'General Science' textbooks, and administered at the end of the 'Science I' course and at the beginning and end of the 'General Science' course. In order to compare the perceptions of science classroom environment, the Perceptions of Science Classroom Environment Questionnaire, which was prepared from the Individualized Classroom Environment Questionnaire. the Science Laboratory Environment Inventory, and the Classroom Environment Scale. was also administered at the end of the 'Science I' course and the 'General Science' course. The results indicated that the mean VOSTS score of the 6th-curriculum group was lower than that of the 5th-curriculum group, although the difference was not statistically significant. The decrease in the VOSTS score of the 6th-curriculum group during the 'General Science' course was statistically significant. It was also found that unrealistic views such as 'technology is the application of science', and 'corporations should control science/technology' had been formed during the course. However, the 6th-curriculum group had more positive perceptions of science classroom environment. Educational implications are discussed.

Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 405~413
High school common science is introduced by the sixth national curriculum. It consists of physics, chemistry, biology and earth science like the secondary school science. In this paper, textbooks are analyzed by the science teachers and the status of the present teaching and learning methods is reported. The detailed results are as follows; 1. Almost high school teachers choose textbook that included little the STS material. More than two teachers are teaching the high school common science and when they are chosen, they are independent with their major. 2. According to the national curriculum, they evaluated the textbooks as it is below the middle level. This evaluations are not dependent on teachers' comparement and textbook's class except the several matters based on STS (science-technology-society). 3. The teacher teaching the high school common science thought that teaching the textbook in school is worse than analysizing it. they must have emphasised on learning of inquire method than system of knowledge, introduction to material connected with real life and STS in the high school common science.

The purposes of this study were to investigate the intercorrelations among various motivational patterns and learning strategies and to examine the differences in motivation and strategy usage in terms of students' science achievement level, gender, and grade. A questionnaire on achievement goal, self-efficacy, self-concept of ability, expectancy, value, causal attributions, and learning strategies was administered to 360 junior high/high school students (178 males, 182 females). Students who adopted performance-oriented goal tended not to be task oriented. Task-oriented students had high levels of self-efficacy, high self-concept of ability, and expectancies for future performance in science. They also valued science and attributed thier failures to the lack of effort. However, performance-oriented students evaluated their ability negatively, did not value science, and attributed thier failures to uncontrollable causes. With respect to learning strategy, task-oriented students tended to use deep-level strategy, whereas performance-oriented students tended to use surface-level strategy and not to use deep-level strategy. High-achieving students, boys, and junior high school students were more task-oriented, evaluated their ability more positively, and valued science more than low-achieving students, girls, and high school students, respectively. High-achieving students and boys also used deep-level strategy more than each of their counterparts. However, no significant difference in learning strategy was found between junior high school students and high school students. Educational implications of these findings are discussed.

Choi, Kyung-Hee ;
Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 425~433
The purpose of this study was to examine for middle school science textbooks published by the sixth curriculum to analyze STS material, activity, and space devoted to STS. Because most teachers and students are dependent upon textbooks in teaching and learning, analyzing science textbooks will give basic information to ascertain the extent to which the current school science incorporate STS themes. Results indicated that lots of STS topics in the middle school science text books are related to applications of science. They also revealed that about 3% of the narrative space is devoted to STS topics, with a range of 0.7% to 5.2%. The coverage of STS topics increases as grade level increases.

The status of facilities, management for the experiment, practices, teaching methods in middle schools have been investigated. The present status and reasonable management of the middle school science education have been grasped from the questionaires. To do this 125 secondary science teachers, 1,745 students and 70 principals of schools in Korea are administered questionaires of Science Education Reserch Institute of Kyungpook National University(1996). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the middle school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper

Various modern social problems are also related with science and technology. Thorough understanding about Technology-Society(STS) interactions is required to take informed action about how to deal effectively with these problems. In this case, there is a need for STS education. The purpose of this study was to examine the perceptions of high -school students and science teachers about Technology-Society interactions and differences of their perceptions. It is my hope that this thesis will contribute to future "General Science" class in Korea. We obtained the data by a survey of 414 high school students who took "General Science" courses in Seoul and 54 of their science teachers. The survey was made using 10 multiple-choice items selected from the VOSTS (Views On Science-Technology-Society) item pool. The results of this study are as follow: 1. More than half of the students and teachers thought that science is exploring the unknown and discovering new things. Their perceptions about the science are somewhat stable, but about the technology various. 2. Most students and teachers thought that science and technology interact and complement each other. They also thought that the improvement in the quality of life needs investments in both science and technology 3. Most students and teachers thought social facts as community, government, and politics influenced scientists and scientific research. They also had a good understanding about the effects of science and technology on society. We can conclude from this that they had a Science-Technology-Society oriented viewpoint. 4. There are significant differences between the perceptions of boys and girls in following categories (p<.05): Influence of Community or Government Agencies on Scientists Influence of Politics on Scientists Role of Scieoce/Technology in Resolving Social Problems 5. There are significant differences between the perceptions of students and teachers in following categories (p<.05): Definition of Science Influence of Politics on Scientists

The concept map is the diagram of two dimensions which hierachically arrays main concepts from those of the textbook and shows their relations. The research analyzed five of the ten high school earthscience textbooks approved by the Minister of Education according to the 6th reformed curriculum in 1995, one of which this research chose to make out the concept maps. The chapter [III. the Universe] contains the outer space of the earth presents new concepts about the stars and the universe and introduces the latest research in astronomy. This study changed textbook contents into Novak's concept map, searched for concepts requiring complement for learners in oder to obtain concepts from those of the textbook and pointed out problems on the basis of that result still better concept map is set up. We have the following conclusions. First, it is necessary to rule out unnecessary small units so as to make more effective understanding and to rearrange the units to have relation to contents. Second, the higher concept and lower concept need to be rearranged systematically in making an array of textbook contents. Third, the concept should have something to do with learners' experences and consciousness by showing learners the real examples relevant to the concept for the link between them.
A Study of Validity in Tripartite Model of "Attitudes towards Science" using Exploratory and Confirmatory Factor Analyses
Lee, Kyung-Hoon ;
Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 481~492
The purpose of this study is to construct validity of Tripartite model of "Attitudes towards Science" using Exploratory and Confirmatory Factor Analyses. Exploratory and confirmatory factor analyses are two major approaches to factor analysis. The primary goal of factor analysis is to explain the covariances or correlations between many observed variables by means of relatively few underlying latent variables. In exploratory factor analysis, the number of latent variables is not determined before the analysis, all latent variables typically influence all observed variables, the measurement errors(
) are not allowed to correlate, and unidentification of parameters is common. Confirmatory factor analysis requires a detailed and identified initial model. Confirmatory factor analysis techniques allow relations between latent and observed variables that are not possible with traditional, exploratory factor analysis techniques. As a result of exploratory factor analysis, tripartite model of "Attitudes towards Science" being composed of affection, behavioral intention and cognition is empirically identified. But attitude of science career being composed of affection and behavioral intention is identified. In validity test using confirmatory factor analysis, measurement structure of Tripartite model of "Attitudes towards Science" is not correspondent to data set. Because it is concluded that the object of attitudes are not specific.

Many science teachers can be able to miswrite the vocabularies for seven kinds of experimental tool names on blackboard of secondary school in Korean language. The diagnosis test for the miswriting possibility was carried out by science teachers in secondary school. We questioned "How can you write each of Korean vocabulary for seven experimental tools?" to each of one hundred and fourty science teachers in three class of physics, chemistry, and biology during inservice training course of Gyeongsang National University on August in 1997. First of all, for the investigation we showed the real things of seven tools to the teachers and they wrote each vocabulary for each tool name on blackboard in English. In addition we explained the general use of each tool name. And then the teachers answered the vocabularies of them on one written paper. The miswriting results for seven tools were as follows. There appeared various miswriting vocabularies for each tool name. For examples, meas cylinder was miswritten two kinds of Korean name and the miswriting ratio of 4%, Mortar & pestle was miswritten four kinds of name and the ratio of 12%, Beaker & desiccator were miswritten one kind of name and the ratio of 51% and 36%, separately. Separatory funnel & spuit were miswritten two kinds of name and the ratio of 54% and 58%, separately. Schale was miswritten four kinds of name and the ratio of 51%. We might conclude that the cause of miswriting vocabularies for the tool name could be due to the original miswriting in Korean-English or English-Korean dictionaries as well as the seience teachers by themselves

Science teachers' beliefs about science and school science and their perceptions of the science laboratory learning environment were investigated with an assumption that science laboratory teaching would be affected by science teachers' beliefs. Likert-scale questionnaires of BASSSQ and SLEI were used in this study. The major findings were as follows: 1. Science teachers showed inconsistent beliefs about science and school science. Their responses reflected a patch-like view of postmodern epistemology and objectivism They also showed somewhat different views about science and school science. It was found that science teachers had strong objectivist views about science in some parts. but they had moderate constructivist views about school science in other parts; 2. The mean scores of student cohesiveness, integration. and rule clarity on the actual version in SLEl were relatively high, but those of open-endedness and physical environment were very low; 3. There was no association between teachers' beliefs about science and their perceptions of the science laboratory learning environment. But some associations were found between teachers' beliefs about school science and their perception on student cohesiveness, integration, and rule clarity of the actual science laboratory learning environment. Teachers' beliefs about school science had some statistically significant correlations with their perceptions on all scales of the preferred version of SLEI. We could not show a causal relationship between teachers' beliefs and their science laboratory learning environment through these results. But it can be suggested that teachers' beliefs about school science do have a role in constructing a desirable science laboratory learning environment, as we found that there were statistically significant correlations between them.

Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 511~524
The curriculum of science should be made of the education based on the acquirement instead of the knowledge. However, the present educational environment has many problems such as lack of laboratory and experimental facilities, and time limitations. One of the suggested methods to overcome the barriers in regular curriculum is the efficient operation of science club activities. Since the club activities are not restricted on time and space, teachers can apply various methods and programs. In this paper, we investigate the present operational status of science club activities in secondary school and some suggested improvement schemes of them It is shown that teacher training, reference development, time allocation, educational environment, facility completion and various program developments should be preceded, in order to activate science club activities.

Hur, Myoung ; Lawson, Anton E. ; Kwon, Young-Ju ;
Journal of The Korean Association For Science Education, volume 17, issue 4, 1997, Pages 525~540
The present study tested the hypothesis that maturation of the prefrontal lobes is a crucial factor determining the performance of scientific reasoning tasks, Functions of the prefrontal lobes, such as activating relevant information, sequential planning and monitoring, and inhibiting irrelevant information, are related thinking patterns with scientific reasoning. Therefore, we inferred the idea that the prefrontal lobes play an important role in scientific reasoning. To test the hypothesis. the present study investigated a prefrontal lobe patient's task solving procedures in scientific reasoning tasks and the correlation and regression analysis between a test of prefrontal lobe function and two scientific reasoning tasks, The perseverative errors in the Wisconsin Card Sorting Test(WCST) was used as a measure of the prefrontal lobe function, The Melinark Type Task and the Classroom Test of Scientific Reasoning were used as measures of scientific reasoning abilities. Ages and Group Embedded Figure Test were also used as measures of two alternative hypotheses, general maturation and field independency respectively. The prefrontal lobe patient showed a crucial deficiency in solving scientific reasoning tasks. In the tasks, the patient could not used the reasoning of If... and... then... therefore pattern. In correlation study, the perseveration errors of the WCST showed a significantly negative correlation with two scientific reasoning tasks. Multiple regression study also showed that the perseveration errors measured as a function of the prefrontal lobes have more contribution to scientific reasoning ability than contributions of alternative hypotheses. Therefore, the present study supported the hypothesis that prefrontal lobes play a crucial role in scientific reasoning ability, What function of the prefrontal lobes do play crucial role in scientific reasoning? The present study provided an explanation for the question, which inhibiting ability of the prefrontal lobes is responsible for the scientific reasoning ability, in a part at least. That is, perseverative tendency in task-solving procedures causes a deficiency of an ability to inhibit the wrong information to solve a task. The present study provided a possibility of neuropsychological approach in science education research. The present study also showed an importance of the prefrontal lobe development in the performance of scientific reasoning task.
