The purpose of this study was to examine the effect of Small-Scale Chemistry(SSC) lab program on the academic self-efficacy and the science-related affective domain of 11th grade science-majored students. For this study, a SSC lab program was developed on the basis of analyzing the textbook of high school chemistry I in the 7th curriculum, and the experimental group was received SSC experiment lessons(SSC group), and the comparison group was received traditional experiment lessons. After students were grouped high and low level according to the students' prior science achievement score, the differences between the two groups were investigated using 2-way ANCOVA. From the result of this study, we found that the SSC lab program was more effective than the traditional Large-Scale lab program based on the textbook in academic self-efficacy. And the scores of interest toward science-related careers and creativity for the SSC group, which are subcategories of science-related affective domain were significantly higher than those for the comparison group. In students' perceptions on the SSC lab program, majority of students thought that the SSC lab program was convenient, effective and interesting.

The purposes of this study were to investigate the correlation between the cognitive level and the probabilistic thinking level and to analyze the effects of the probability activities in Thinking Science (TS) program on the development of probabilistic thinking. The 219 7th grade students were sampled in the middle school and were divided into an experimental group and a control group. The probability activities in TS program were implemented to the experimental group, while only normal curriculum was conducted in the control group. The results of this study showed that most of 7th grade students were in the concrete operational stage and used both subjective and quantitative strategy simultaneously in probability problem solving. It was also found that the higher the cognitive level of the students, the higher the probabilistic thinking level of them. The sample space and the probability of an event in the constructs of probability were first developed as compared to the probability comparisons and the conditional probability. The probability activities encouraged the students to use quantitative strategy in probability problem solving and to recognize probability of an event. Especially, the effectiveness was relatively higher for the students in the mid concrete operational stage than those in any other stage.

We investigated middle school students' awareness of Han-style(Korean cuture) in order to promote it, and developed and applied the Teaching-Learning Lesson Plan according to the traditional clothing culture contents related to Han Style. We selected 5 major fields representing Han Style including Han-gul(Korean alphabet). Han-sik(Korean food). Han-bok(Korean traditional clothes). Han-ji(Korean traditional paper), and Han-ok(Korean traditional house). We analyzed the contents of the food, clothing and shelter in 6 types of high school testbooks under the revised 7th national curriculum, and chose seven traditional clothing-lifestyle culture contents. Also we developed 14-period processes and materials(9 for teachers. 9 for students and 3 for and applied it to usual classes. The mean score of middle school students' awareness of Han Style in the post-test was significantly higher than that in the pre-test. Students evaluated it positively that the classes could raise the pride on the Han-culture and provoke the interest in it through the direct experiencing activities. We suggest that the various themes on Han-style should be developed, and the theoretical classes on the identity as well as the experiencing activities on it.

This study examined the moral judgments and ethical decision-making and analyzed ethical dilemmas experienced in practice by nursing students. The data were collected using self-reported questionnaires and reports from 189 college students in their 2nd ~ 4th grades. Data collection period was from Nov 6th - 20th in 2012. Each grade's P(%) scores were 47.92, 43.74, and 43.75 respectively.. For stage 4 score, each grade's scores were 22.37, 22.98, and 19.74. This result shows that, compared to juniors, senior student's P(%) scores did not drop and stage 4 scores rather decreased, which is in line with the results of previous studies about the effects of ethics education. This finding could be attributed to the regular and voluntary case presentations and discussions required for the senior participants. Regarding ethical decision-making type, the most favored was type 3(35.45%). Among seven categories of the ethical dilemmas facing the students, the most commonly reported was the patient's rights and dignity, followed by practices based on nursing standards, arranging for dying patients. This study raises the need that the curriculum is revised to encourage student's participation in the analysis of ethical issues they confront in the field.

Modern society requires people with practical knowledge that is able to recognize actual problems in the complex reality and solve the problems. Due to that reason, the 7th National Curriculum aims to basically cultivate ability adaptable to information-oriented global age by maximizing students' individuality and creativity. However, as existing education is hard to improve creativity, logical thinking, information processing skills, and problem-solving ability in the information-oriented age, self-directed learning is getting highlighted. Therefore, this study aimed to look into how learner-oriented IPER for self-directed learning and problem-based learning(PBL) in middle school science affected academic achievement of science and self-directed learning characteristics. As the results of the study are as follows. First, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on learners' academic achievement increase, it showed that the class with IPER instruction model was more effective. Second, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on self-directed learning characters, IPER was more effective than PBL overall, and among sub-areas, 'openness', 'self-concept', 'initiative', 'future-oriented self-understanding', and 'self-evaluation' were more effective in IPER while 'creativity' was more effective in PBL. However, among sub-areas 'responsibility' and 'learning enthusiasm' didn't show statistically significant difference. Third, the results of the post-survey to compare and analyze learners' perception regarding the application of IPER instruction model and PBL instruction model, the two models were positively affective. In addition, as the result of comparing the two models, IPER was more positive than PBL.

Students' affective attitude not only influences their achievement in a meaningful way but is also an important educational goal in its own right. This research investigated how students' interest in science varies among elementary, middle, and high-school students based on surveys and reviews of previous research results. We analyzed students learning attitude in terms of (1) interest in and enjoyment of science, (2) instrumental motivation in science, (3) science learning anxiety, and (4) self-concept in science. Major findings are that students showed more negative attitudes in intrinsic motivation, instrumental motivation, value perception of science, and confidence in science as they move in to a higher school level. According to the students' explanation, science classes get boring in higher grades because of difficult contents, lack of experiments and activities, and the teachers' monotonous explanations. Based on the results, recommendations on how to improve students' attitudes towards science are suggested. First of all, we need to secure more science instructional hours in the school curriculum than the 7th national curriculum to implement improved science teaching and learning methods.

For this purpose the problems as following are selected centering on the hygiene education contents of the 7th education process in Korea and Japan and the hygiene text of public school in California, USA. First, this study tries to analyze the composition classified by 12 guidance contents each grade of hygiene education contents of elementary schools in Korea, USA, and Japan. Second, this study tries to analyze the composition classified by fields(physical, mental, social) of hygiene education contents of elementary schools in Korea, USA, and japan. As a result of the analysis and comparison on the matters stated above, the conclusion as following was gotten. First, as a result of searching the hygiene education contents system of elementary schools in Korea, USA, and Japan classified by 12 guidance contents each grade, the subjects which have good contents composition classified by class step by step were safe life and disease prevention. And the subjects such as growth development and health, physical fitness, drug use and health were weak and the parts such as consumer health and the careers concerned with are not dealt in the present education process of Korea at all. Second, as a result of analyzing the composition classified by fields of hygiene education contents of elementary schools in Korea, USA, Japan, all the three countries put great on physical part. And there are 57 units about mental part in USA, 27 units in Japan, only 17 units in Korea. And this fact reveals that there was lack of understanding about the need of mental part in Korea. This study tries to suggest improvement method as following through the study results stated above. First, as it is grasped in the analysis classified by guidance part of hygiene education contents, community and environment preservation, physical aptitude and stress management are to be emphasized more strongly and about the parts like consumer health and the persons concerned with hygiene new education programs as contents satisfying the need of age are to be inserted or complemented Second, because the hygiene education contents in Korea are still lack in comparing contents of mental parts compared with those of the two countries, the contents proper to the level and the requirement of learners to each grade are to be developed and complemented. Third, hygiene education units which were reduced in the 7th curriculum in Korea are lack compared with those in the two countries. Therefore, it is necessary that teachers should recognize the need of hygiene education so that the hygiene education can be separated and be taught out regularly.
