  • In this study, four gifted students in the second year of middle school at Gifted Education Center of the National University in Jeollanam-do were surveyed students' perceptions of the effectiveness of science class using science writing heuristic in terms of metacognition and the goals of the 2015 revised science curriculum. Through questionnaires and interviews with gifted science students, science gifted students recognized that the science class using science writing heuristic had a positive effect on the four subdomains (planning, monitoring, control, and evaluation) of metacognition. For this reason, the science gifted students presented self-directed experience in designing experiments, continually checking the collected experimental data, feedback process, and reflecting experience in preparing conclusions. Science gifted students recognized that science class using science writing heuristic had a positive effect on the goals of the 2015 revised science curriculum(attitudes, inquiry, knowledge, Science·Technology·Society(STS), and the enjoyment and usefulness of science learning) that correspond to through inquiry science writing lessons. For this reason, the science gifted students presented self-directed inquiry experiences, continual inquiry experiences on the same subject, thinking process at each stage of inquiry, learning experiences through inquiry, experience of the whole inquiry process, and inquiry of phenomena closely related to real life. Therefore, for the effective science class, it is necessary to apply the characteristics of science class using science writing heuristic which is responded by science gifted students to general science class as well as science gifted class later.

  • The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

The Perception of Middle School Science-Gifted Students on the 'Science Writing Heuristic' Class Emphasizing Social Interaction and Tool Improvement (사회적 상호작용과 도구 개선을 강조한 '탐구적 과학 글쓰기' 수업에 대한 중학교 과학 영재 학생들의 인식)

  • In this study, a science writing heuristic class with emphasis on social interaction and tool improvement for 10 middle school students at the National University Science-Gifted Education Center in Jeollanamdo was conducted to investigate the perception of STS (science technology society) relationship and students' perception of the effects of class. After science writing heuristic class emphasizing social interaction and tool improvement, the students became aware of the STS relationships as follows: Science-gifted students have come to perceive that experimental tools and technology contribute to the development of scientific theory, that it is difficult to solve all social problems with only science and technology, and that science is a social interaction activity. In addition, science-gifted students responded that they became aware of the relevance of STS through intensive inquiry conducted on the same subject for several hours, communications with colleagues in another group through peer reviews, communication to solve problems with colleagues in the same group, activities to improve tools in the process of inquiry, inquiry using familiar materials and phenomena. In order for students to effectively recognize the relationship of STS in science-gifted class for middle school students, it is necessary to provide experience to solve problems using various experimental tools, experience to have trial and error in the process of solving inquiry problem under the same subject, experience to improve tools in the process of solving inquiry problem, experience to communicate with colleagues who conduct inquiry activities under the same subject, experience to share the results with other groups, and inquiry activities using familiar materials and phenomena.

  • The purpose of this study was to explore changes of elementary science class in student oriented group inquiry activities using a Science Writing Heuristic (SWH) template that enhance scaffolding of inquiry. The changes focused on students' written reports and perceptions of their learning environment as well as discourse patterns. One fourth-grade class of 29 students participated in this study, and a developed work sheet of science writing was utilized to scaffold student's inquiry activities. Four units in the first-semester text book for fourth grade of the-, 2007 Educational Curriculum Revision were chosen for scaffolding inquiry, and sixteen lessons of instruction were all videotaped. For investigating students' written reports, a framework based on the aspects of science inquiry by Millar (2010) was used to evaluate the coherence between student inquiry activities and their claims. Secondly, a regular fourth-grade class was selected as the control group and was compared with the experiment group using the pre- and post-test of the survey on the perception of science class and science. Lastly, students' discourse patterns of the beginning science lesson were compared with those of the closing lesson. We found that the coherence in the last class increased significantly in students' written reports compared to the first one. Findings also indicated that students' perceptions on their learning environment moved toward student-centered. Based on our discourse patterns analysis, the last class was more student-centered from being teacher-centered than the first one.
