  • Recognizing the importance of abductive inquiry in Earth science, some theoretical approaches that deploy abduction have been researched. And, it is necessary that the abductive inquiry in a geological field excursion as a vivid locale of Earth science inquiry should be researched. We developed a geological field trip based on the abductive learning model, and investigated students' abductive inference, thinking strategies used in those inferences, and the impact of a teacher's pedagogical intervention on students' abductive inference. Results showed that students, during the field excursion, could accomplish abductive inference about rock identification, process of different rock generation, joints generation in metamorpa?ic rocks, and terrains at the field trip area. They also used various thinking strategies in finding appropriate rules to construe the facts observed at outcrops. This means that it is significant for the enhancement of abductive reasoning skills that students experience such inquiries as scientists do. In addition, a teacher's pedagogical interventions didn't ensure the content of students' inference while they helped students perform abductive reasoning and guided their use of specific thinking strategies. Students had found reasoning rules to explain the 01: served facts from their wrong prior knowledge. Therefore, during a geological field excursion, teachers need to provide students with proper background knowledge and information in order that students can reason rues for persuasive abductive inference, and construe the geological features of the field trip area by the establishment of appropriate hypotheses.

  • The purpose of this study is to develop a project-based learning program utilizing Earth science data and to evaluate its effects on students' knowledge-information processing competency and communication and collaboration competency. To achieve this, the ADDIE instructional design model was employed to create the program, which was then implemented with 75 second-year middle school students. The program's effectiveness was assessed using paired sample t-tests on the results of tests measuring knowledge-information processing competency and communication and collaboration competency. Additionally, reflection journals were analyzed to identify students' interest in and difficulties with the program. The study's conclusions are as follows: first, the Earth science data-based project learning program comprises three themes: 'Journey through the Planets of the Solar System,' 'I am a Marine Expert,' and 'Planning a Tidal Flat Experience Program.' Second, following the program's implementation, there was a significant improvement in the overall students' knowledge-information processing competency. Third, the program also led to a significant enhancement in students' communication and collaboration competency. Based on these findings, the study suggests the need for specific and continuous teacher support to provide students with successful experiences through the program, overcoming challenges in program implementation through collaboration with the information subject, and conducting research that microscopically analyzes students' interactions.

  • This study investigated the relationships among middle school students' understanding about the nature of scientific knowledge, conceptual understanding, and learning strategies. Grade 7 students (N=162) in Incheon completed the nature of scientific knowledge scales (NSKS) and a learning strategy questionnaire. After learning density by way of a CAl program, a conception test was administered. Results indicated that students' conceptual understanding and both deep and surface learning strategies were significantly correlated to their understanding about the nature of scientific knowledge. A cluster analysis was used to classify students on the basis of their deep and surface learning strategies. Three clusters of students with distinctive learning strategy patterns were found; high deep-low surface strategy (cluster 1), low deep-high surface strategy (cluster 2), and high deep-high surface strategy (cluster 3). One-way ANOVA results revealed that the scores of cluster 3 were significantly higher than those of the others in the NSKS and the conception test. Additionally, cluster 1 also performed better than cluster 2 in the conception test. Lastly, educational implications were discussed.

  • The purpose of this study was to examine the effects of formative assessment with detailed feedback on students' science achievement, attitude, and interactions between the teacher and the students. For the study, 133 seventh graders were selected from a girl's middle school in Seoul, and assigned to the experimental and the control groups. The duration of the treatment was over a period of nine weeks. In the experimental group, detailed feedbacks on the solution, teacher's comments on the results, and relevant references were provided after each formative assessment. However, only the answers were presented in the control group. Prior to instructions, a achievement and a attitude tests were administered. After the instructions, follow-up tests which were similar to the pretests were also administered. The results showed significant difference between the two groups in science achievement. It was found that the usage of formative assessments with detailed and supportive feedbacks was more effective in stimulating students' interest, raising their confidence in the subject, increasing their participation, as well as reducing their anxiety. The results also strongly indicated that detailed feedbacks were more effective in improving the interactions of the teacher and the students. The results strongly suggest that formative assessment utilizing detailed and supportive feedback is a necessary component of effective science teaching and learning.

  • The purpose of this study was to examine middle school students' (N= 153) perceptions of motivational climate (teacher learning/teacher comparison/peer learning/peer comparison/peer worry) and their achievement goals (task/performance/performance-avoidance). The influence of perceptions of motivational climate emphasized by science teachers and/or peers on achievement goals was explored by stepwise regression. Although there was no difference in male/female perceptions of motivational climate, there was significant difference in their achievement goals. Regression result indicated that the pursuit of learning by peers made the strongest contribution to students' task goal. On the other hand, promotion via comparison by science teachers or peers had little effect on inducing performance goal. Anxieties about mistakes were found to be the strongest contribution to predictions on students' performance-avoidance goal. The promotion of comparison by science teachers was related to not only performance goal, but also performance-avoidance goal. Lastly educational implications for intervention efforts designed to enhance the quality of student motivational development in science education are discussed.

  • The purpose of this study was to investigate the effects of the instruction with question-creation training, compared with traditional science instructions. The instruction with question-creation training is to give students chances to make questions by themselves based on what they learned before the end of the classes. The four effects of the instruction were studied: students' achievement, metacognition, self-efficacy, and the level of the questions created by the students according to different proficiency levels. Research data was gathered from 65 second grade students at a middle school in Busan. The comparative group was instructed in traditional lecture-type teaching method. The experimental group was instructed with questioncreation training. Students in the experimental group were asked to make 3 questions by themselves and then, to solve their peers' questions about 15 minutes before the end of the classes. Both groups were divided into 3 groups by proficiency level according to the results of last semester's science test. Before the research, a metacognition test and a self-efficacy test were conducted. After the research, an achievement test, a question level test, a metacognition test, and a self-efficacy test were conducted and analyzed by t-test. The research data for question level was analyzed by one-way ANCOVA. The results of this study revealed that question-creation training has a positive effect on student's achievement, metacognition, and self-efficiency. It also showed most of the students have gained an ability to make higher-level questions regardless of their proficiency level due to the increased number of students who made higher-level questions. It also showed that most of the students could gain an ability to make higher-level questions regardless of their proficiency level from the fact that the number of students who made higher-level questions increased in every proficiency level.

  • This study aims to develop a field trip program for the Hantan River geopark in Pocheon using Orion's field trip model. The selected learning sites were the Hwajeogyeon and Bidulginang Falls, famous geosites of the Hantan River geopark in Pocheon. The field trip program consisted of six preparatory units, two field trip units, and two summary units. The preparatory stage helped reduce the novelty space considering cognitive, psychological, and geographical factors. In the field trip stage, students acquire concepts linked to learning elements in the curriculum scientifically and encourage interest in science. In the summary stage, students organized the geological phenomena observed in the field and inferred the vicinity of the Pocheon Hantan River region. The field trip program was modified to give enough time for observation activities to increase students' interest in science and to connect concepts with learning elements in the curriculum in the outdoor learning phase to allow students' convergent thinking. Implementing the field trip program raises students' interest and attitude in science.
