Programming is very important subject in computer science and similar computer-related areas such as electronics engineering, etc. Programming is also important for information education for elementary, middle, and high school students since programming is one of the most basic subjects in computer science courses and other similar areas. In current information and knowledge society, raising programming ability is a key factor for everyone's competitiveness. With highly-competitive programming ability, one can enjoy his or her daily life abundantly. He or she also can get a highly-paid job, and make money using his or her programming ability. In this paper, a programming ability assessment tool is developed and introduced for the no-programming experienced. It is very difficult to test programming ability for the no-programming experienced with non-programming tools or activities. In this paper, a programming ability assessment tool is developed based on logical thinking ability. Especially the proposed tool consists of 15 questions for test one's logical thinking ability. The tool does not require any computer science or programming background. The proposed tool will be helpful as criteria for entrance examination or job screening examination for programming-related areas or subjects.

In this study, the relationships among learners' cognitive variables, motivational variables, and conceptual understandings in learning with analogy were investigated. The instruments regarding analogical reasoning ability, field dependence-independence, mental capacity, and logical thinking ability were administered. Some subtests (self-efficacy, expectancy, self-concept of ability, and value) of the Patterns of Adaptive Learning Survey were administered. After students learned with a worksheet that included analogy, a conception test regarding 'stoichiometry that included limiting reagent' was also administered. It was found that learners' conceptual understandings were significantly correlated with the logical thinking ability and the field dependence-independence among the cognitive variables, and the self-efficacy and the self-concept of ability among the motivational variables. The multiple regression analysis of the cognitive variables on conceptual understandings revealed that the logical thinking ability was the most significant predictor. The field dependence-independence also had predictive power. In the analysis of the motivational variables, the self concept of ability was the only significant predictor.

The purpose of this study was to explore logical thinking abilities and metacognitive characteristics by student's giftedness and grade level. Furthermore, this study sought to present the practical basis for the promotion of students' abilities in self-driven learning as well as cognition. Average-ability students(n=199), economically disadvantage gifted students(n=133), and gifted students(n=111), who were sampled by two-step sampling procedures, responded the logical thinking ability test(Cho et al, 2006) and the questionnaire asking self-perception for 'metacognitive knowledge' and 'metacognitive control' abilities(Cho & Han, 2004). As the results, average-ability students showed less logical thinking abilities(in language, mathematics, and space) than gifted students. The logical thinking abilities had affected by giftedness, grade level and these interaction. And gifted students showed higher metacognitive control abilities in planning, monitoring, priority, and strategies of learning than average-ability students. However, there were no significant differences in metacognitive knowledge and metacognitive control abilities between economically disadvantaged gifted students and gifted students.

The purpose of the study is to meta-analyze research results on Korean students' logical thinking ability. The results of meta-analysis on the research studies between the year 1980 and the year 2000 show that about 40-50% of Korean middle school students have conservation reasoning, proportional reasoning and combinatorial reasoning abilities, and that about 25-30% of them have control of variables and probability reasoning abilities. In addition, only 8% of the Korean middle-school students have correlational ability. When comparing their logical thinking ability results with those of Japanese and American middle-school students, The ratio (32.6%) of Korean middle-school students who have formal thought ability is a little higher than that of American students (30.6%), but much lower than that of Japanese students (50.1%).

The purpose of this study is to develop a Python sorting algorithm training program based on execution time as an educational method for enhancing the logical thinking power of elementary students and then to verify the effect. The education program was developed based on the results of the pre-demand analysis conducted on 100 elementary school teachers. In order to verify the effectiveness of the developed educational program, I teached 25 students of the volunteer sample of the elementary school education donation program conducted at ${\bigcirc}{\bigcirc}$ University conducted 42 hours, 7 days. The results of the pre-test and post-test were analyzed using the 'Group Assessment of Logical Thinking(GALT)' developed by the Korea Educational Development Institute. The results showed that the Python sorting algorithm training centered on execution time was effective in improving the logical thinking ability of elementary school students.

It is necessary for us to be equipped with problem-solving ability, logical thinking ability, and convergence thinking ability in the digital information age. To have these abilities, modern people in the $21^{st}$ century should be educated to develop the computational thinking ability. However, it is difficult to cultivate the computational thinking ability in current computer education curriculum. Therefore, this paper aims to propose a programming-based computer educational program to make students better understand the principles of computer science and enhance student's computational thinking ability escaping from current fragmentary and limited computer education. In order to verify the effectiveness of the educational program, students in total 42 middle school (22 students in 1st and 2nd grades and 20 in 3rd grade) were applied to the educational program for twenty-four hours on 12 weeks and then we obtained a positive result that might bring improvement on the logical thinking ability and creative problem-solving skills. As a result, this study presents the possibility of its field applications of computational thinking-based programming learning and analyzed the effectiveness. therefore, it has a notable point of presenting the development direction of a variety of education programs for enhancing the computational thinking in the future.

In this study, students' understanding of the analogies used for chemical concepts in science textbooks, misconceptions induced by the analogy, and the factors affecting conceptual understanding were investigated. In addition to the tests of field independency and logical thinking ability, tests of students' understanding of concepts and analogies on three states of matter, pressure-volume relation, molecular motion, and changing state depending upon energy were administered. The results revealed that half of the subjects understood the analogies differently from the textbook writers' intention and that students' conceptual understanding was significantly correlated with the degree of understanding on corresponding analogies, field independency, logical thinking ability, and prior achievement of science. The results of analyzing the direct and indirect effects of each variable on conceptual understanding showed that the direct effect of prior achievement was significant and that field independency and logical thinking ability had indirect effects through understanding of analogies and prior achievement of science. The limitations and implications of using analogies in science education were discussed on the basis of the results.

The purpose of this study is to verify the effects of the advance organizer in programming class on elementary school students' logical thinking ability and self-efficacy. We developed our teaching-learning materials of programming for this purpose, Further, they are applied to the elementary school, and their effects are analyzed. Fourth grade students in elementary school were selected for the experiments of this study, For comparison, they were divided into a control group who taught by a traditional programming teaching method and an experimental group who taught by our advance organizer programming class. As a result, through before-and-after t-verifications performed on the experimental group and the control group respectively, we found statically significant differences between the two groups, and the effectiveness of our new programming teaching method was proved in both learner's self-efficacy and logical thinking ability.
