The purpose of this study is to investigate the misconception about circulatory / excretional system and to determine the effectiveness of two teaching strategies. The subject was 214 middle school students. The control group was instructed with the traditional teaching method.On the other hand, the experimental group was taught with the concept mapping teaching method. Then the effectiveness of the two teaching strategies were compared in terms with the changes of their conceptions about circulatory/excertional system. The major findings of this study are as follows. 1. The major misconception types were identified. 1) The function of blood is only transportation. 2) The artery is equal to arterial blood. 3) The colon and the anus are also excretional organs. 4) Urine is formed from the bladder. 5) Urine and feces are also excrement. 2. Different conceptional change was observed between control group and experimental group at 0.05 significance level. The concept mapping strategy was more effective than traditional teaching method. 3. No significent difference was found between male and female students in the effectiveness of concept mapping strategy.

We have investigated the effect of the substrate temperature and hydrogen flow rate on the characteristics of IGZO thin films for the TCO (transparent conducting oxide). For this purpose, IGZO thin films were deposited by RF magnetron sputtering at room temperature and 300℃ with various H₂ flow rate. Experiments were carried out while varying the hydrogen gas flow rate from 0sccm to 1.0sccm in order to see how the hydrogen gas affects the IGZO thin films. IGZO thin films deposited at room temperature and 300℃ showed amorphous. The lowest resistivity value was 0.379×10^-5 Ωcm when the IGZO film was deposited at 300℃ and set up at 1.0sccm. As the oxygen vacancy rate increased, the resistivity intended to decrease. In conclusion, Oxygen vacancy affects the IGZO thin film's electrical characteristic.

The purpose of this study is to investigate the self-perceptions of the elementary school students' on the affective, behavioral and cognitive domains in science class. To see if there are differences in students' perceptions according to grade levels, a self-perception questionnaire was applied to third and fifth grade students in Seoul, Korea. The major results of the study are as follows. First, the perception level of the affective domain was higher than that of the cognitive domain in third grade students. There was no significant difference in the self-perception level of the fifth grade students. Both third and fifth grade students perceived the greatest improvement in the cognitive domain through one year of science teaching. Second, in the life science class, the same tendency was also observed. The students in the third and fifth grade reported that cognitive domains were the most improved through the one-year life science class. Third, when the students' perceptions were compared by grades, the third grade students showed higher self-perception scores than fifth grade students. As the grade increased, the perception scores of the students' lowered. Based on these findings, implications for science education research and teaching and learning at school are discussed.

The purpose of this study is to identify the difficulties of learners who started programming after entering college and to search an effective software education method as university liber arts for non-science major students. In order to do this, we analyzed the difficulties of learners in Python programming classes composed of students from various majors at H University through questioning and taught them using flipped class model with pre-questions. The questions that students submit are collected online before class every time, the data on the degree of the difficulty of feeling and the understanding of feeling were obtained through the questionnaire. As a result, for learners who are new to programming, the learners should allocate the process of making the problem into a logical abstraction at the beginning of the curriculum before learning the basic concept of computer language, each lesson should be practiced through the bottom-up problems enough to provide a logical understanding before actual coding. In addition, detailed curriculum should be developed according to characteristics of learner's major, contents and conducting level.

The purposes of this study are to investigate elementary students' perception of science classroom through an analysis of students' answer to an open-ended question and to suggest a framework for the analysis of science classroom culture, as the first step to develop an analysis tool for qualitative exploration of science classroom culture. We analyzed 571 responses and developed an analysis framework with six categories (i.e. major factors; power structure of a classroom community; focused domains of the science classroom; student concerns; atmosphere of science classroom; participation form). The details of the six categories can be summarized as follows: (1) major factors were revealed to be practical work, fun, teacher, community and others; (2) the power structure of classroom community was in the order of peer students, teacher, and individual student himself/herself; (3) the focused domains of the science classroom perceived by students were more about affective and behavioral domains than cognitive one; (4) major student concerns were teachers' teaching, having practical work, and the understanding of and the sharing of knowledge and opinions (5) science classroom atmosphere was noisy and pranky but fun and interesting; (6) the students participation forms were to be total participation or voluntary participation or cooperative practice. Through this study, not only suggesting the framework, but we could also get implications for the cultural aspects of science classroom based on the results of data analysis in this study.
