This study was conducted to investigate the effect of PBL applied environmental writing class on the climate literacy and environmental sensitivity of 43 5th grade students. To carry out this study, an environmental writing class that applied PBL in the 8th class was developed and applied to examine the effect. The conclusions of this study are as follows. First, the environmental writing class applying PBL had a statistically significant effect on improving the climate literacy of elementary school students. Statistically significant results were found in the cognitive and definitional domains, excluding the sub-domain of climate literacy. Second, the environmental writing class applying PBL has a significant effect on improving the environmental sensitivity of elementary school students. Statistically significant effects were found in all sub-domains of environmental sensitivity, sensitivity, aesthetic sense and emotional stability, and sympathy and compassion. The reason why the environmental writing class applying PBL was able to improve the climate literacy and environmental sensitivity of elementary school students is that students actively participate in the class to solve environmental problems and realize that environmental problems are deeply related to our real lives.

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.

For engineers in the knowledge-based society of the 21st century, not only the specialty in their major field, but also the capabilities of creative thinking/reading/writing, of communication and of understanding society/business/economy, and the knowledge of specialized liberal arts, like ethics, are required. For the specialized liberal arts knowledge, it is important to have interest in a field, read the relevant literature, and summarize and express thoughts, but in reality, it is difficult to accomplish a higher level of learning outcome within the limited regular curriculum. In this study, an application for smart phones that purports to cultivate the specialized liberal arts knowledge of the students enrolled in the college of engineering was developed and applied to classes. Under this environment, a teacher can interact with teacher's students through the structured knowledge on a real-time basis in any place at any time, and the students can reorganize the knowledge by themselves. In this way, this paper proposed a way of improving the level of specialized liberal arts knowledge in daily life.
