  • This study aims to identify the characteristics of the program that integrates maker education with science subjects and to explore the maker's competency expressed in students. To this study, a maker activity program based on scientific concepts was developed and applied to 20 first-year students at H University in a general chemistry experiment course, and activity data were analyzed. The analysis results of maker activities based on scientific concepts are as follows. First, students performed activities through the process of 'presentation of ideas,' 'selection and planning of ideas,' and 'prototyping'. In particular, it was confirmed that prototyping was divided into stages of "partial prototyping" and "full prototyping". Second, as characteristics of the activity, 'use of scientific concepts as logic for coding in the process of maker activities', 'in-depth understanding of scientific concepts', and 'inducing high achievement and interest through transfer of initiative in learning' were confirmed. Third, collaboration competency and making performance competency were frequently expressed in the process of activities, but human-centered competency were rarely expressed.

  • The purpose of this study was to analyze laboratory instructions in a secondary school science with an analysis instrument on science laboratory instruction. For its purpose, we used an instrument that analyzes three dimensions of the secondary laboratory instructions. This analysis instrument was composed of 3 categories (the aim of the laboratory activity, interaction, and inquiry process) which are spread into 20 sub-categories, and its validity was checked by four science educators with factor of 0.89. For its purpose, 21 sessions of lab instructions were video-recorded and transcribed. According to the results, in the aims category, the instructions mainly focused on two aims; acquiring the declarative knowledge and increasing attitudes toward science. In the interaction category, some of the observations made were that the teachers's questions could not gather the students' divergent thinking, their directive instructions were centered around themselves rather than giving opportunities for students to be centered within laboratory activities, and students' interaction were rarely shown. Therefore, interaction was classified as level I. In the inquiry process, presenting phenomenon or questionings about the subjects were little observed, and students' hypothesizing and predicting were almost nonexistent. Most of the activity designs within lab session were given from the teachers' directions or worksheets, and students solely focused on data collecting and recording. Hence, inquiry process were classified level I.

  • The purpose of this study is to investigate the contents of open inquiry activities of the newly revised 2007 National curriculum for each grade level and to teach open inquiry activities and selection of rational inquiry activities. For this study, 470 elementary students in Seoul, ranging from 3rd to 6th grades were surveyed. The experiment plans written by students were analyzed based on the analysis criteria. These criteria consisted of the reason for the selection, type, and suitability of open inquiry activities. The reason for selecting open inquiry activities were analyzed according to the reason why they want to conduct the activity, degree of getting help and the object of getting help. The types of the open inquiry activities were analyzed according to the field of inquiry, the inquiry method and the period of inquiry. Suitability of the open inquiry activities were analyzed according to the reason of suitability or unsuitability.

  • The purpose of this research was to investigate how the peer review activity of lab report in the problem-solving experiment effected on the description ability and the quality improvement. The students who were taking the general chemistry experiment course were the subjects for this study. They finished lab reports and received peer review from their peers more than two times. The students who got feedback answered on peer review, revised their reports, and subsequently, completed final reports. The result showed that peer review affected the qualitative improvement of the lab report, specially in the process of 'designing experiment' and 'drawing conclusion and evaluation'. Students could organize their thoughts through writing lab reports. During this process, peer review activities provided the opportunity of self-examination and the way for viewing as objective standpoint. Moreover, the activities established communication fields for exchanging mutual opinions and learning.

  • What does mean the statement that scientific reasoning is logical? In this study, we clarify the logical structure of the scientific explanation, prediction and the process of hypothesis testing. To simplify and identify the structure of scientific explanations and prediction more clearly, we used syllogism and presented various concrete examples. Especially, we showed that the logical structure of scientific explanation was well reflected in dynamics. Based on this analysis, it can be said that the deficit of students' understanding of dynamics is because that many scientific activities are focused on prediction rather than explanation. To explain the process of hypothesis testing, we reinterpreted the Wason's selection task as two stages: the process of prediction of experimental phenomena based on the presented hypothesis, and the process of the hypothesis testing based on the predicted experimental phenomena. And we suggested the reason of the logical fallacy of 'affirming the consequent' in science was because that many scientific relationships between the variables is one-to-one relationship, and compared this suggestion with the Lawon's multiple hypothesis theory. To check out the effect of content on the deductive reasoning, we reviewed some researches about psychology and psychology of science. And to understand the role of deductive reasoning in student's scientific activities, we reviewed researches about the analysis of students' responses in the task of conceptual change or evaluation of evidence and so on.

  • The purpose of this study is to consider the implications of science experiment in class and to seek a direction for its improvement. For this purpose, Science textbooks, teachers' cognitions, and classroom activities have been analyzed to find out how many and what kind of levels of inquiry elements are included in those. In this study, 22 teachers have participated in the questionnaire to investigate their perception about experiment class, and the two instruction cases in two classes of 9th grade have also been analyzed. Results show that most of the textbooks have included questioning, evidence collecting, explanation of phenomena, and connection with existing scientific knowledge. But the elements of communication and justification have been few. Most levels of the inquiry are teacher-led. Although the teachers thought communication and justification are important, their classroom activities does not coalesce with their thoughts. The students mostly spend their time with connecting evidence, they hardly explain the phenomenon based on the proofs as the results of experiment, and the activities of connection with the existing scientific knowledge, and communication and justification.

  • In this study, we explored the philosophical perspective of Ian Hacking on experimentation and discussed its potential impact on science education in schools. Traditionally, many philosophers have advocated a theory-driven view of experimentation, emphasizing its importance primarily in validating theories. Similarly, in the context of education, the prevailing perspective has been to focus on experimentation primarily as a means of confirming and proving theories. However, in contrast to this theory-driven perspective, philosophers like Hacking have proposed that experimentation itself possesses autonomy and vitality. Through their discussions, they have brought to light the significance of previously overlooked elements in experiments, such as tool usage, materials, and the involvement of scientists. They have prompted a reevaluation of the role and importance of experiments in scientific activities. Therefore, in this study, we consider the application of this philosophical standpoint to school experimental education. We anticipate that the phenomenon-centered perspective we propose in this research will be beneficial for teaching scientific practices, including tool usage, the involvement of experimenters, and modeling activities.

  • The purpose of this study is to explore students' epistemic goals and considerations in designing an experiment task and to investigate how a shift in the students' epistemology affected their argumentation. Four 7th grade students were selected as a focus group. According to the results, when they designed their own experiment, their epistemic goal was 'scientific sense-making' and their epistemic considerations - the perception of the nature of the knowledge product was 'this experiment should explain how something happened', the perception of the justification was 'we need to use our interpretation of the data' and the perception of the audience was 'constructor' - contributed to designing their experiment actively. When students tried to select one argument, their epistemic goal shifted to 'winning a debate', showing 'my experiment is better than the others' with the perception of the audience, 'competitor'. Consequently, students only deprecated the limits of different experiment so that they did not explore the meaning of each experiment design deeply. Eventually, student A's experiment design was selected due to time restrictions. When they elaborated upon their result, their epistemic goal shifted to 'scientific sensemaking', reviewing 'how this experiment design is scientifically valid' through scientific justification - we need justification to make members accept it - acting as 'cooperator'. Consequently, all members engaged in a productive argumentation that led to the development of the group result. This study lays the foundation for future work on understanding students' epistemic goals and considerations to prompt productive argumentation in science classrooms.

  • The purpose of this study is to provide some suggestions for future improvement of scientific inquiry activities in Korean elementary science textbook. The modified framework of Lee(2005) and Millar et al.(1998) was used to compare inquiry activities in the Korean and Singaporean science textbooks. The results of this study are as follows: Korean text books have more activities than Singapore's, but both countries have similar time allotment for science classes. In the area of 'inquiry process skill', Singapore is more balanced in 'Basic inquiry process skills' and 'Integrated inquiry process skills' than Korea. Singapore's integrated inquiry rate is also higher than Korea's. Next the results of comparing leaning objectives to scientific inquiry activities shows that Korean text books tend to focus on 'contents objectives', while Singapore's text books focus on balancing 'contents objectives' and 'process objectives'. Korean science textbooks encourage students to communicate the results of experiments but in most case these communication activities are actually not performed. Lastly Korea and Singapore have low degree of openness in inquiry activities. Remarkably 'Suggest questions' are totally conducted by teachers. This study implies that Korean science textbooks should have lower amounts of inquiry activities to accomodate enough time for communication about results. Next we need to make balance not only 'Basic inquiry process skills' and 'Integrated inquiry process skills' but also 'Content objectives' and 'Process objectives'. Lastly we need to make student to be the leader in science classes through encouraging them to plan procedures for experiments and to discover results by themselves.
