The aim of this study was to identify students' views on the orientation of science and to investigate the relationship between their views and decision-making on socio-scientific issues (SSI). In this study, 27 university students attending a science course were asked to discuss four controversial issues: the Toyota recall, the green car, the global warming and swine influenza (influenza A (H1N1)). The study was comprised of two stages. At the first stage, we examined students' views on the nature of science and on the orientation of science with the open-ended questionnaire based on VNOS and VOSTS. While they held relatively similar views on the nature of science, their views on the orientation of science were distinct as pragmatic, intrinsic, communal and ethical views. At the second stage, to examine the role of their views on the orientation of science in decision-making, we selected four students who had similar views on NOS but different views on the orientation of science. The four students were selected from each group of views on the orientation of science and their decision-making processes were analyzed following grounded theory. Across SSIs, they relied upon their views on the orientation of science as the strategies for decision, though considered different perception, and causal and contextual conditions. This study indicates that understanding students' views on the orientation of science would be helpful for achieving scientific literacy for informed decision.

Whether and when naturalistic or supernaturalistic explanations of the origins of sun and earth, humans, life and species change with development was explored in a questionnaire and interviews with 32 first graders and 32 second graders, and in a questionnaire with 34 third graders, 32 sixth graders and 38 eighth graders. Participants were also asked about factors affecting their explanations in the questionnaires. Even the first and second graders could consistently provide supernaturalistic or naturalistic explanations on both the origins of sun and earth, and of humans. There was an age-related developmental shift from supernaturalistic to naturalistic explanation. As for origins of species, most of the first and second graders held the spontaneous generationist explanation, and after the third grade their views divided into evolutionist and creationist explanations. Students' explanations of species origins were established by the sixth grade through a transitional stage in the third grade. At the first and second grade levels, books and the children's own reasoning mainly influenced the views of origins, whereas parents and school were not perceived as being important. For the third graders and higher-grade levels, several factors, including parents and religion, were perceived as being important. These results show that explanations of origins start to develop earlier than or during the first grade, and are established by the sixth grade; moreover, the formation of these views is affected by several factors in addition to development.

The purpose of this study was to investigate the elementary students' views about lab-based science learning. For the purpose of this study, semi-structured interviews were conducted with thirty sixth grade students in 12 classes from two elementary schools located in Daegu City. The interview contents consisted of three major categories. The first category was related to attitude toward science lab, the second was related to lab-based science learning which had four sub-categories; recognizing lesson object, planning experiment, performing experiment, drawing conclusion in lab-based science learning in which the students had ordinary have views and expectations, and the last category was related to students' difficulties and something need to be improved in lab-based science learning. In-depth interviews were performed individually and the interviews were recorded. From the interviews, we found that students, in first category, do like lab-activities more than lectures or instruction-based activities in textbook. Students, in second category, wanted generally more discussion for their own activities rather than teacher's instruction and they wanted teacher' mediation conflicts within small groups and comments for students' experiment results. In the last, most of students had fears for some dangerous reagents and accidents. Based on the results, the study suggested that teacher need to give their students to autonomous discussion opportunities to design and interpret data through teacher' guided questions in inquiry steps, to produce some intimate atmosphere for active interaction in small groups, and to teach the safety education on some dangerous reagents.

Researchers continue to emphasize the centrality of proof in the context of school mathematics and the importance of proof to student learning of mathematics is well articulated in nationwide curricula. However, researchers reported that students' performance in proving tasks is not promising and students are not likely to see the need to prove a proposition even if they learned mathematical proof previously. Research attributes this issue to students' tendencies to accept an empirical argument as proof for a mathematical proposition, thus not being able to recognize the limitation of an empirical argument as proof for a mathematical proposition. In Korea, there is little research that investigated high school students' views about the need for proof in mathematics and their understanding of the limitation of an empirical argument as proof for a mathematical generalization. Sixty-two 11^th graders were invited to participate in an online survey and the responses were recorded in writing and on either a four- or five-point Likert scale. The students were asked to express their agreement with the need of proof in school mathematics and to evaluate a set of mathematical arguments as to whether the given arguments were proofs. Results indicate that a slight majority of students were able to identify a proof amongst the given arguments with the vast majority of students acknowledging the need for proof in mathematics.

In the past, the judicial circles in the Republic of Korea (ROK) were generous to the online copyright violations of computer software compared to other academic areas or offline violation. However, they started to reconsider such a practice since the FTA talks with some advanced countries began so that new laws had to be established, especially after the first round of negotiations with United States of America (USA) in 2006 during which they changed their views on the matter. Now it became possible to penalize digital copyright violations through lawsuits, and from March 1st, 2017, the court is expected to abolish the nonsuit system for teenagers. Thus, this paper has reviewed the ethical aspects involved in digital copyright protection and examined the possible alternatives, dividing them into three broad groups, before proposing a digital copyright protection curriculum for secondary education.
