  • The purposes of this study were to develop a program utilizing learning strategies for underachieving middle school students in science and to identify the effectiveness of the program on the ability of using learning strategies and the improvement of science academic achievement. For this study, we developed the program of learning strategies consisting of eleven consecutive lesson plans focusing on the content of 2009 revised national science curriculum and applied the program to three underachieving students in science of 7th grade, who have weaker learning strategies that can be used for science study than other underachievers. After treatments, we analyzed the effectiveness of this program through science learning strategy tests, overall assessments, student-activity sheets, research logs, learning-transcription details, analysis of interviews with students, and observation of classes. According to this study, the enhancement of the ability of using learning strategies was limited because it was difficult for the students to change their fossilized strategies. On the other hand, their overall academic performance was considerably improved since the students became interested in studying science drawing on the learning strategies. Therefore, the program of learning strategies had a positive effect on improving the science underachievers' ability of using learning strategies and academic achievements.

  • The purpose of this study was to analyze 9th grade students' understanding about the earth science terms written by Chinese characters depending on their loaming style and attitudes toward science. The study selected the eight students with the middle level of science achievement and divided into four groups: verbal-high attitude toward science, verbal-low attitude toward science, visual-high attitude toward science, and visual-low attitude toward science learners. Three types of questionnaires including Korean characters type, a picture type, md Korean and Chinese characters type were developed to determine the students' understanding about the earth science terms written by Chinese characters. The results of data indicated that the 9th grade students' understanding showed no significant difference by their different teaming style, and yet demonstrated higher level of understanding in Korean and Chinese characters type questionnaire rather than Korean characters type only or a picture type. On the other hand, the level of students' understandings both in Korean characters type and a picture type was about equal. In conclusion, it seems more effective in students' teaming about the earth science terms written by Chinese characters when they were provided with both Korean and Chinese characters.

  • The purpose of study is to develop the web-contents for web based instruction (WBI) with the Science Fiction Movie (SF) and investigate the effects of application to the science learning. The results are as follows. 1) Science fiction movies for the earth science classes of middle school were selected, that is the Armageddon, the Apollo13 and the Total Recall. They are related to the chapters, the Earth and the Stars in the 8th grade science textbook. 2) The developed WBI materials were applied to the science classes of the 2nd grade in middle school through the Internet Line. and then the changes of attitude on science and recognition on using the science fiction movies to the class were analyzed. The results show that the science fiction movies have so much related to the contents of science learning and the developed WBI materials are effective to the science classes(p<0.05), but no meaningful (p>0.05) to the attitude on the science excluding the students' interest to science learning.

  • This study investigated the causal relationships between high school student multiple-choice algorithmic chemistry problem solving and 1) the motivational variables of achievement goal (task goal/performance goal/performance-avoidance) and perceived ability, and 2) the cognitive variables of learning strategy (deep learning/surface learning) and self-regulation. Path analysis supported a causal model in which perceived ability and task goal were found to positively influence algorithmic chemistry problem-solving ability via self-regulation. In particular it was found that perceived ability directly influenced algorithmic chemistry problem-solving ability. Moreover, deep learning was found to have been influenced by perceived ability and task goal, while surface learning was influenced by performance-avoidance goal. Lastly, there did not appear to be any causal relationship between learning strategy and algorithmic chemistry problem-solving ability.

  • The purpose of this study is to investigate pre-service middle school earth science teachers' perceptions about the learning of geological field trip. The study sample consists of 39 undergraduate students at the university located in a metropolitan city. Additionally, 4 pre-service earth science teachers are semi-structure interviewed. The instrument of the study includes a 5-category perception about the learning of geological field trip, which consists of needs, educational values, educational experience, teaching methods, and training for learning. The results are as follows. First, participants are important to the need and educational values of learning about the geological field trip regardless of gender and grade level. Second, all participants have experienced geological field trip in college. They have more opportunities to experiment for field trip as they advance to higher grade. There is significant difference between lower and higher graders in terms of the goal of learning about geological field trip. It needs a new lesson model to teach geology between men and women regarding teaching methods category. In order to practice geological field trip in school, participants perceive that they need the knowledge of geological context, experiment of field trips, and how to teach geological field trip to students. This study suggests that pre-service earth science teachers' perceptions include how to teach and learn geological field trip during their college year.

  • The study aims to investigate self-regulated learning ability (SRLA) of students and analyze its relationship to their science inquiry skill and affective domain of science in middle schools in Korea. For this end, the research questions include the followings: First, what level is SRLA of middle school students? Second, how does the relationship between SRLA and science inquiry skill look like? Third, how does the relationship between SRLA and affective domain of science look like? A research method employed in the study is the survey utilizing three questionnaires: a) a questionnaire of SRLA (Jung et al., 2004); b) a questionnaire of problem finding ability of the science inquiry skill (Jung et al., 2004); and c) a questionnaire of science affective domain (Seo et al., 2008, adopted from 2006 PISA Student Questionnaire). Responses to three questionnaires by 704 students from seven middle schools in Busan, Ulsan, and Gyeongnam in Korea were analyzed. The research findings were as follows: First, mean average scores of SRLA is 3.02 (${\pm}0.63$) in 5 Likert scale (1 = strongly disagree; 5 = strongly agree). Second, students with higher scores in science inquiry skill showed significantly (p<.05) higher scores in SRLA than others. Third, boys scored higher on self-efficacy scale than girls. As students advance their grade level, their affective domain levels of science significantly (p=.048) decreases, in particular, their self-efficacy level most significantly (p=.002) decreases. Fourth, SRLA was significantly (p=.000) correlated with science inquiry skill and affective domain of science. In conclusions, it appeared that the higher SRLA level of students in middle schools is, the higher level of science inquiry skill and affective domain of science is.

  • The purpose of this study was to explore science teacher's epistemological understanding of science and science teaching and learning, from the perspective of inquiry as the process of scientific knowledge building. Three science teachers participated in this study. The data were collected from individual in-depth interviews and classroom videotaping. The results show a case involving coherent and consistent data. It showed that the teacher's epistemological understanding of science and science teaching and learning consisted of five categories: scientists doing science with scientific thinking; scientific thinking as the process of knowing; science learner in the learning process of scientific thinking; science teacher as a man/woman with good understandings of science; and teaching and learning as the process of knowing science. Based on the results, discussions and implications about science education and science teacher education were presented.

  • The purpose of this study was to develop the brain compatibility index equation for the brain-based analysis method of science teaching-learning program. To develop the index equation, one sample unit in middle school science programs was selected and analyzed by the brain-based analysis frame (CORE Brain Map). Then, the index equation was derived by the CORE Brain Map. In addition, four sample units in elementary science programs were selected to validate the brain compatibleness index equation. From the random network theory of Erdos and Renyi, this study derived the brain compatibility index equation; (BCI=$\frac{L_o}{11(N_o-1)}{\cdot}{\sum}\limits_{i=1}^4l_iw_i$) for quantitative analysis of science teaching-learning program. With this equation, this study could find the quantitative difference among the teaching-learning programs through the unit and curriculum. Brain-based analysis methods for the qualitative and quantitative analysis of science teaching-learning program, which was developed in this study is expected, to be a useful application to analyze and diagnose various science teaching-learning programs.

  • The purpose of this study is to investigate science teachers' orientation toward scientific inquiry-based teaching. In this study, five middle school science teachers formed and participated in a teacher learning community for scientific inquiry-based instruction during one year. Data collection consisted of pre and post questionnaire and interviews, audio-recordings of teachers' collaborative lesson planning and reflection on teaching practice, and field notes of participant teachers' teaching practice and follow-up interviews. Data analysis indicated that there were four orientations toward scientific inquiry-based teaching. They were knowledge and beliefs about 'goals of scientific inquiry-based teaching', 'scientific inquiry-based teaching and learning', 'argumentation-based teaching and learning', and 'nature of science and science inquiry'. Teachers' collaboration in a teacher learning community would be effective in facilitating teachers' orientation to scientific inquiry-based teaching.
