The purpose of this study was to identify the effectiveness of science writing on organizing scientific knowledge and improving science process skills and science attitude, as science educators have indicated. For this study, two classes of $5^{th}$ grade students were chosen in the same elementary school. Subjects were divided into an experimental and a control group. The students in the experimental group took part in a science writing program for 14 lessons of science classes. The students in the control group were taught according to the traditional science program using standard science textbooks. To identify the effects of science writing, both groups' students were tested on science achievement, science process skills, and science attitude before the program implementation and were tested on science concept, science process skills, science attitude after the program implementation. The results of this study showed that the experimental group gains significantly higher scores than the control group in science concept and science attitude, but there was no significant difference on science process skills for either group. In conclusion, science writing had positive effects on science concept and science attitude of elementary school students, helping them to express their thinking logically and systematically, but science process skills were not affected.

In this paper, we propose a think-aloud program for acquiring abstraction concept. Think-aloud is a technique, which is good for teaching higher-order thinking skills to learner. We intend to propose a program for teaching abstraction concept to learners directly, as software education is being reinforced in the current education policy. For the study, we develop a program depending on ADDIE model. According to these steps, we analyzed related works such as computational thinking, think-aloud technique, and direct instructional model. After that, we split and structuralized the learning tasks for achieving a goal. And then, we constructed steps for the instruction and detailed contents of the program. We did a survey for verification to nine experts and we corrected the program according to it.

This study investigated gender differences in the factors affecting elementary school students' ability to identify scientific problems. Scientific problem finding tasks, involving written instruments including IQ tests, content knowledge, science process skills, divergent thinking skills, intrinsic/extrinsic motivation, personality traits, and home environment were administered to 96 elementary school students(male; 50 & female: 46). The data collected was analyzed by means of a t-test, Pearson's correlation, multiple regression analysis, and canonical correlation analysis. The finding indicated that there were significant gender differences in scientific problem finding performance. Female students were significantly higher in both total score and elaborate score of scientific problem finding than male students. Personality traits and intrinsic motivation positively and extrinsic motivation negatively predicted male students' abilities in scientific problem finding. Science process skills, personality traits and intrinsic motivation positively and extrinsic motivation negatively predicted female students' scientific problem finding and IQ positively predicted female students' elaborate score of scientific problem finding.

Purpose: To develop a Critical Thinking Skill Test for Nursing Students. Methods: The construct concepts were drawn from a literature review and in-depth interviews with hospital nurses and surveys were conducted among students (n=607) from nursing colleges. The data were collected from September 13 to November 23, 2012 and analyzed using the SAS program, 9.2 version. The KR 20 coefficient for reliability, difficulty index, discrimination index, item-total correlation and known group technique for validity were performed. Results: Four domains and 27 skills were identified and 35 multiple choice items were developed. Thirty multiple choice items which had scores higher than .80 on the content validity index were selected for the pre test. From the analysis of the pre test data, a modified 30 items were selected for the main test. In the main test, the KR 20 coefficient was .70 and Corrected Item-Total Correlations range was .11-.38. There was a statistically significant difference between two academic systems (p=.001). Conclusion: The developed instrument is the first critical thinking skill test reflecting nursing perspectives in hospital settings and is expected to be utilized as a tool which contributes to improvement of the critical thinking ability of nursing students.

The purpose of this study was to test the effects of the Lasater's debriefing on critical thinking disposition, problem- solving skills and clinical judgement of nursing students. The study design was a nonequivalent control group non synchronized design. The subjects were 60 students for 12 groups. They were randomly assigned to the experimental group (n=30) or control group (n=30). Critical thinking and problem-solving skills were measured using a self-administered questionnaire. Clinical judgement was measured by a Lasater's clinical judgement rubric. The Results of the study was : After Lasater's debriefing, the level of students' critical thinking, problem-solving skills and clinical judgment in experimental group were higher than the level of control group. Through this experiment the rubric of Lasater debriefing is an effective tool for clinical judgment, therefore we know that the future of simulation training is needed to use the Lasater's clinical judgement rubric of debriefing in simulation training.

This study aims to examine the differences between groups through the results of the core competency diagnosis, and to find out the differences in core competences depending on engineering education accreditation, gender, admission types. To this end, we analyzed the differences in K-CESA results on self-management capabilities, resources & information use, global competency, higher order thinking competency, and interpersonal competency in 2017 for the fourth graders of S University. An ANOVA of major field showed that the humanities had high overall competencies. The results of t-test of engineering students showed that accredited students had relatively low "flexibility" of their global competency, and that the "analysis" of their higher order thinking competency was relatively high. There were no statistically significant differences between groups depending on the admission types. Through these analyses, we presented suggestions such as the provision of specialized programs based on differences among different groups, the development of comprehensive thinking skills such as capstone design, the need to secure flexibility in engineering education accreditation, and the enhancement of female students' resources & information use.

Scientific reasoning is one of the main concerns in current science education. This study have tried to answer on the question whether Korean science education has the potential to help improve of students' ability to think scientifically. Therefore, the present study investigated the relationship between reasoning patterns evident in science textbook and science examination items, and students' scientific reasoning skills across grades in Korea. 1975 subjects (1022 females and 953 males) were administered in the Lawson's Test of Scientific Reasoning skills. Forty seven science textbooks and 240 assessment instrument were analyzed by several scientific reasoning keys. Scientific reasoning patterns were adopted from Lawson's classification which characterized the patterns as the empirical-inductive and the hypothetical-deductive. This study found that reasoning patterns evident in textbook analyses and assessment instrumental items do not evidentce the potential to stimulate the development of students' reasoning skill. In order to improve the students' abilities to think and achieve, higher levels of reasoning must be included in the science textbook and examination. Further, some of scientific reasoning processes, such as generating hypotheses, designing experiments, and logical prediction, were not found in science textbooks and test items in Korean secondary schools. This study also discussed the educational implication of these results and further studies about to develop student's reasoning ability.

In order to assess students' higher mental abilities, such as scientific inquiry thinking skills, the essay type items would be more adequate than the multiple choice itmes. However, due to the present condition in which a huge number of students take the examination at the same time, it is inevitable to use the multiple choice type. For this reason, it is necessary to develop a new type of multiple choice items which can reduce the disadvantages of the traditional multiple choice type and can achieve a similar level of validity as subjective type assessment. The three-tier multiple choice test items which can be used for a large sample of students and especially for scientific inquiry thinking abilities, are proposed and examined. The three-tier multiple choice test items asked firstly conclusion or the results of calculation or experimental apparatus, secondly the processes of calculation or of developing conclusion, thirdly asking relevant scientific concepts. For the item analysis, 1 point was given to the correct answer, while 0 point was given to the wrong one. The data were processed through the computer program developed in Turbo C 2.0 language with an IBM compatable personal computer. The average score in the sub-items asking for scientific concepts was lower than that in the sub-items asking for results or processes. The score of guessing by chance in the three-tier multiple choice items was only 0.13%, so that the probability of making correct answers by just guessing would be extremely low. The three-tier multiple choice items, even if they are objective items, are thought to assess thinking skills of the scientific inquiry meaningfully excluding the possibility of guessing by chance.
