Wing, J. M. emphasized the importance of computational thinking competency to live in the 21st century. In this study, the abstraction of computational thinking is classified into object abstraction, data abstraction, and procedural abstraction through related studies. In addition, abstraction achievement and assessment standards were developed for the abstractable competency assessment. As a result of applying to the school site, the students showed that the object abstraction and the data abstraction competency which are expressed in writing and drawing, they are excellent in solving the problem. However, students hard to write a computer program. The abstractable competency assessment developed in this study will help teach students to teach software education.

It has been pointed out that the mathematics textbooks according to 2009 revised national curriculum cause difficulty not by mathematical knowledge but concomitantly by words and sentences for the first graders who just started learning Korean alphabets. This study focused on the suitability of words and sentences in mathematics textbooks for elementary first grade. We analyzed the degree of difficulty and familiarity in terms of words and the structure, length, and expression in terms of sentences. The results show some causes that lead the first graders to the difficulty. In more detail, we found 108 difficult words and 6 unfamiliar words for the first graders. And it is noticed that the textbooks contain 37 compound sentences, 727 complex sentences, and 38 compound-complex sentences. They also contain 237 long sentences that are composed of 9 words or more, 168 sentences that assign two activities or more, and 52 sentences that contain three nouns or adjectives or more successively. Based on these results and discussions, we suggested several implications for writing mathematics textbooks for the lower grades in elementary school.

Students are exposed to many visual representations in various visual cultures. Infographics combining visual representations and writing can effectively convey information. Also it can be efficient ways for teachers to focus on important contents. Students can use infographics as a method directly to organize information. Therefore, the infographics that students use both writings and images directly and visually will be more effective on elementary school science classes than the workbook. Classes are guided with the same scientific inquiry and experiment written on the science textbook. The experimental group students organized scientific inquiry by infographics, while the comparison group students still used the workbook. First, the types of infographics are determined by what students want to explain. Based on learning objectives, students used the right type of infographics to effectively convey their focus on information. Second, the infographics organizing activities used in the classes had a significant effect on students' academic achievement. Also, the infographics organizing classes are positively associated to science-related attitudes, including such+ as 'Leisure Interest in Science', 'Adoption of Scientific Attitudes', and 'Attitude to Scientific Inquiry'. Third, visual tendency and classroom treatments had no interactions, but the experimental group had a positive impact regardless of student's characteristics. Fourth, experimental group showed positive attitudes toward to students' perception of infographics. Since some of students had difficulties organizing information in infographics, further research is required to enable students to reduce their burden in application of infographics.

The purpose of this study is to understand the characteristics of the questions presented in shapes area and Measurement area of elementary mathematics textbooks. For this purpose, the types of questions presented in shapes area and measurement area of elementary mathematics textbooks and their working functions were comparatively analyzed by area and by grade cluster. As a result of the analysis, the number of questions per lesson increased sharply in the 3rd and 4th grade cluster compared to the 1st and 2nd grade cluster in both shapes area and measurement area. In these two areas, the most common reasoning questions are presented. It is presented relatively more in measurement area than in shapes area. There was a clear difference between the types of questions presented in shapes area and measurement area. In common with the two areas, questions mainly were acted as a function to help students learn to reason mathematically, a function to help students to determine whether something is mathematically correct, and a function to help students learn to conjecture, invent, and solve problem. The characteristics of the questions identified in this study can provide teaching/learning implications for the design and application of the questions suitable for the guidance of shapes area and measurement area, and can be used as a reference material when writing mathematics textbooks.

The purposes of this study are to analyze the merits and limits of flipped learning by suggesting the ALP model for efficient application and to test the effects of the new ALP model. The process of new model and program development is based on ADDIE in this study. This study consists of two steps. First through literature research on the difficulties of the flipped learning, the elements are extracted to develop new model. Second, these elements were placed according to the teaching and learning flow, which resulted in the procedures. As a result, the ALP model was developed. The ALP model is a new model for applying teaching and learning methods for efficient application of the flipped learning. This model was applied to elementary science classes to test its effects in scientific communication skill. Interviews and cognitive survey were also conducted to collect additional information. The results of this study are as follows: There were various difficulties in flipped learning. Based on literature research results, the ALP model and the science programs for elementary students have been developed. The experimental group showed statistically meaningful improvement in scientific communication skill. The scientific communication skill has two subcategories: the forms and the types. According to the form analysis results, the experimental group showed a statistically meaningful improvement in the form of Table and Picture, but not in the form of Writing and Number. With the same reason given previously, this study confirmed that the application of ALP model improves the students' visual form communication skills such as Table and Picture better than reading form communication skills such as Writing and Number. According to the type analysis results, the experimental group showed a statistically meaningful improvement in "the scientific insistence" type, and "the justification" which is the sub element of "the scientific insistence" type. With this reason, this study suggests that the class applied ALP model gives students more time and opportunities to learn. Though the survey and interviews about the student's awareness of the class with applied the ALP model, this study showed that students actively exchanged their opinions in the class with applied ALP model.

The purpose of the study was to develop a practical arts textbook for creative problem solving abilities in elementary school. In this study the practical arts textbook and teacher's guide has the following characteristics: they were developed to promote creative problem-solving ability, and to instill curiosity and interest about the subject matter. The procedure for the development of the practical arts textbook for creative problem solving abilities is composed of 4 steps; the planning and preparation stage, the research and developmental stage, the writing and compilation stage and the deliberation and improvement stage. This procedure for the development of a textbook can apply to both government published textbooks and to authorized textbooks. The validity of the writing and compilation stage's practical arts textbook developed model is the highest at 4.21, followed by the research and developmental stage's average, at 4.14. Among the textbook's stages of development, the importance of the deliberation and improvement stage averages the lowest, at 3.50.

Establishing and evaluating science education policies and revising and monitoring the effectiveness of science curriculum should be based upon the results of systematic and scientific research studies. Advanced nations have already been administering and developing national level science assessments for these purposes. The science assessments administered in Korea have been reported having many limitations and problems, and not succeeded in providing data for science education policy making and curriculum reform. The major purpose of the study is developing national level science knowledge assessment system in order to identify longitudinal trends of elementary and secondary school students science knowledge achievements. The research team consisted of science education experts and teachers from various school levels, decided the directions and major elements of national level science knowledge assessment with the consultation of educational evaluation experts. Item developing ability of the researchers was improved by seminars? and workshops on national assessment in advanced nations and developing skills of writing science items. Nearly 500 items were developed and revised. Pilot test was administered with 958 students at various school levels. 380 items were selected and tested with 8766 students, and the characteristics were analyzed in terms of item response theory. The target populations for national level science knowledge assessment are 5th-grade of elementary school, 2nd-grade of middle school, 1st and 2nd-grade of high school students. The proper period for the assessment is February every year. Multi-stage clustered sampling method is desirable and rotated forms are recommendable for the test format. Bridge items should be introduced to compare the results of multiple tests, and various grades. Anchor items should also be used for longitudinal interpretations of the results. The items for elementary school require low to medium abilities, for middle school and first grade of high school require medium to high abilities and for 2nd-grade of high school high abilities. The discrimination ability of the items developed is high.

The 2009 revised curriculum has been revised to increase the time allocated to creative discretion. Accordingly, in many schools, discretionary activities have been replaced by reading and essay writing. However, these activities do not differ from existing classes and student's interest in those activities is minimal. This study has applied two kind of the AR program, which is designed and implemented using Smartphone in the classroom, to increase student's interest. A browser-based AR, created by Junaio and QCAR-authored Smartphone-based AR fairy tale book, are easy to use in class by the students themselves. We applies to Fourth grade student in reading education this AR programs. As a result of test, the students in actual reading classes responded that their interest in the lesson and their understanding of fairy tales has increased.

The aim of this study is to develop and suggest the handle for lockers according to the design process which are used for keeping of student's personal stuffs such as books, writing implements and gym uniform in elementary, middle and high school and university as well. This includes the design development for ILGUMTUR which is specialized for office furniture, but does not own the intellectual property right yet. The design concept based on the domestic locker market survey is recessed handle at low- to intermediate price and it's material should be plastic what is solid and light. The lock system should be constructed by molding process and the name plate can be exchanged every time the owner of locker changes. Contrary to the right angle of it's external appearance, the handle of the locker is designed to be softly round and the simplicity is pursued for an easy production. On the basis of this design concept the sketch has been drawn and upgraded in full by 3D-rendering. Then the mock-up has been completed by 3D printer and ILGUMTUR has obtained a patent for the locking system based on the rotation of 2 circles.
