  • The subject of this study were 7th grade three students in a school in Seoul, Korea. They discussed the inquiry problem to be investigated during summer vacation. We analysed the process of how the inquiry problem is revised and improved to more investigative one in the discussion. Student always discussed the method in the light of problem and the existence of the method of a problem affect the endurance of problem. The main subject of a problems are in everyday context, which is the object of critics in discussion. Student respond to the critics in many ways. Main types of reaction to the critics are two kinds. One is a person who change their views to the critics, the other is a person who kept their ideas.

  • Software (SW) education is guided by the government to operate not only computer subject matter but also related subject matter. SW education is highlighted in the 2015 Revised Curriculum and Guide for Operating SW Education. SW education is related with science education. For example, education on algorithms employing SW and activities using sensors/output control can be an effective strategy for scientific inquiry. The method can also be applied in developing Computational Thinking (CT) in students. In this study, we designed lessons to solve everyday scientific problems using Educational Programming Language (EPL) SW and physical computing materials and applied them to high school students. We conducted surveys that were modified from questionnaires of Internet application capability and based on the standard of accomplishment of SW education as well as elements of CT to find out the change in perceptions on programming and CT of students. We also conducted a survey on students' attitude toward science learning after an SW inquiry activity. In the results, perceptions on programming and CT of students were improved through lessons using unplugged activity, EPL SW, and physical computing. In addition, scores for interest, self-directed learning ability, and task commitment were high.

  • This study asked preservice elementary teachers to conduct an inquiry of observing the moon, and analyzed the phenomena observed, difficulties experienced, and pedagogical suggestions by the preservice teachers. Participants were 31 undergraduate students enrolled in a science course in a university of education. As a part of the course, the preservice teachers observed the moon for about a month and completed personal journals which described the phenomena they observed, difficulties they experienced, and the pedagogical suggestions to help elementary students conduct the same inquiry activity. The analysis of the journals revealed that the preservice teachers observed the moon mostly during the evening or night and that they noticed lunar phases, directions, altitudes, and color and brightness more frequently than other phenomena. The preservice teachers experienced difficulties related to the observation time, lunar phases, directions, and altitudes, and, reflecting on their own experiences, suggested a variety of pedagogical ideas about these difficulties. The pedagogical suggestions by the preservice teachers also included how to help elementary students keep their interest and perform the moon observation for a rather long period of time. Implications for moon investigations in the elementary school science classroom and relevant research were discussed.

  • The study aimed to analyze middle school students construction of physics inquiry problems for open inquiry from the viewpoint of variable isolation and clarification, and investigate students' difficulties during the processes of variable isolation and clarification to get implications for teaching and learning strategies for small group open inquiry activities which have been included in the 2007 national curriculum. The participants were 4 students who had attended an outreach program for the science gifted run by a university institution located in Seoul area. They performed an open inquiry on egg drop for 13 lessons for 30 hours. Level descriptions for variable isolation and clarification have been developed and applied to analyze students' inquiry problems and variables included by the problems. Students iterated inquiry processed 5 times and the inquiry problem showed progress gradually. Dependent variables have been isolated ahead and the levels of variable isolation and clarification showed higher than the independent variables. Many kinds of independent variables isolated extensively and the independent variables and control variables have been mingled. One of the reasons why students had some difficulties in isolation of independent variables could be the absence of theoretical models. The realities of school lab could restrict the variable isolation and clarification as well as topic selections. Some sensory or extensive variables such as broken eggs and drop height seem to be salient to be focused on as core variables. Lack of background knowledges could be one of the reasons for students' difficulties in variable clarification, such as theoretical definitions and operational definitions. As a result of lacking background knowledges, students could not construct theoretical models even though they could isolate and clarify variables as scientific lexical definitions. Some perceptions of inquiry as trial and error or reckless establishment of causal relations between variables could be accounted as one reason.

  • This study analyzed activities in chemistry chapters of middle school science textbooks for the 2009 revised curriculum using 8 science practices. All the activities that students could experience inquiry were analyzed in this study. There were the most activities in 'Molecular motion and change of state' and the least activities in 'Heat and our life' of three textbooks. There were the most science practices in 'Features of substance' in two textbooks, but there were the least science practice in 'Heat and our life' of three textbooks. 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing' were frequently included, but 'asking questions and defining issues' was not included at all. For 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing', a variety of achievement goals were targeted while a few goals were frequently targeted. Two to four kinds of science practices were frequently included in an inquiry activity. There were few activity that includes over 5 different kinds of science practice.

  • The purpose of this study is to analyze the teaching-learning effect of using self-regulated learning strategy on experimental classes for the 'kinetics' unit of 10th grade science textbook. Six classes were chosen and classified into two groups: the first group, the control group, was taught with the regular laboratory activity and the other group, the experimental group, was taught with the teaching-learning method using self-regulated learning program. After the laboratory activity for the unit using self-regulated learning program, the mean values of the scientific inquiry, scientific attitudes, and performance assessment of the experimental group were larger than those of the control group. There were significant differences between the two groups in the post-test. With the results of the post-test for the experimental group, the self-regulated learning program has significant relationships on scientific inquiry, scientific attitudes, and scientific achievements.

  • The purpose of this study is to examine how well students can acquire scientific knowledge from the process and activity presented in the textbook. This is achieved by analysing of comparison on the material area in the 6th and 7th national curriculums' 3rd and 4th grade science textbooks. The method of this study is to analyse the contents, teacher's instruction and illustrations of the textbooks in the material area in both 6th and 7th national curriculum's 3rd and 4th grade science textbooks. Following is the result of the study. First, compared to the 6th national curriculum's content. 7th national curriculum is composed by phenomenon and activity focused. This considers student's developmental stages and abilities of concentration so one topic in the textbook is divided into 16 small contents. Therefore the textbook content of the 7th curriculum seems to have desirable changes. Secondly, teacher's instruction in the textbook of the 7th curriculum has impartial distribution in part Ⅰ and part Ⅱ according to Homey's analysis. This shows that some problems of writing textbooks that were pointed in the 6th curriculum have been improved. Thirdly, the content of the textbook emphasizes inquiry process as the 6th curriculum did. The 7th curriculum, however, more deeply deals with expecting and inferring. Finally, the analysis of illustration shows that the proportion of motive induction is high. This is also desirable approach to give students more interests in studying science.
