The purpose of this research is to increase mathematical problem solving abilities VIa STAD evaluation after completing classes. to which ST AD group study is applied, and promoting the learning accomplishments of students by developing gradual self-leading learning materials about the research project on ' How to use an hour math class efficiently\ulcorner ' For this purpose, the items below were studied. Firstly, gradual self-leading learning materials were developed and applied which were composed of textbook abstracts, basic problems, developing problems and intensive problems rather than existing textbooks. Secondly, the ST AD group study model was selected and applied which invokes competitions among small groups of which learning goals were clear. individual responsibility was important. and successive opportunities were equal. The evaluation using STAD at each end of a chapter was announced instantly using the EXCEL scoring system. Though the results of experimental classes were limited in their size. experimental time, and class selection, there were meaningful changes in the aspect of being able to heighten the accomplishment desire of students by inducing voluntary competitions among small groups without any student omitted. As the result of applying this research to my class, the ST AD group study using gradual self-leading learning materials invoked the interests of students and increased learning accomplishments via increasing problem solving abilities in mathematics. The ST AD group study was easy to use by beginning teachers, and its process was simple. It increased interactions among students and learning motives because its compensation system was open to all students. Among various studying methods for small groups. STAD group study is expected to be widely used for mathematics classes.

This paper aimed to design a computer course teaching-learning strategy for (m-learning?) to be used in a Problem Based Learning (PBL) environment. The research findings were as follows. Firstly, learning contents were provided as educational tools for mobile device usage. The educational contents provided were designed for effective usage on mobile devices, such as smartphones, thereby making mobile devices suitable for use as learning tools. Secondly, learning contents for PBL were provided. PBL problems (for computer engineering courses) were made with the principles of teaching plans. The learning objectives were achieved through the problem-solving progress of the learners and their self-directed and cooperative learnings. Thirdly, learning resources were provided that were easily accessible through smartphones, laptops and PDAs. This study is about the PBL instructional design of creative engineering design subjects, which aims to foster talent. The PBL model developed in this study consists of Analysis, Design, Development, Implementation, and Evaluation. We made a plan for creative engineering design subjects based on PBL, and focused on the process of PBL. This research was able to establish the basis for PBL usage in Engineering Schools and help achieve its ultimate goal of endowing professional intellectuals with creative problem-solving abilities.

The purpose of this study were to develop PBL(problem-based learning) program, and to examine the effects of PBL. This paper applied PBL to a "Culture of Clothing" class, comprised of 23 undergraduate students majoring in Home Economics. As part of the PBL curriculum, the class assigned students to design and create brochures about the culture of clothing by going on field trips to the National Folk Museum of Korea. The class met for five weeks, 3 hours per week. The effectiveness of PBL was measured based on the students' self-reflective journals, self-assessments, and satisfaction surveys. The study gathered three major feedbacks from the students after taking the PBL class. First, the students recognized the importance of cooperation and communication in problem-solving process. Second, the students appreciated that students themselves were implementing the self-directed learning. Third, the students were satisfied with the overall quality of the PBL class, based on their feedbacks and surveys. However, the students' self-assessments show their acknowledgement of the lack of creativity and critical-thinking skills. The study also observed relatively low-satisfaction ratings about the learning environment at the National Folk Museum of Korea.

This study examined a possibility of a new learning method using a robot to improve elementary school students' creativity and problem solving ability. It researched and analyzed school teachers' tendency about robot education and based on this it developed curriculum and teaching materials to teach and evaluate the education after school. According to the findings, a robot is found to have a possibility of a creative learning method.

This study compares and analyzes the mathematics assessment items of the middle school's national-level academic achievement tests in Korea and Japan, recently revised as a competency-focused curriculum. By comparing and analyzing the assessment items in each country, the analytic framework is integrated into content areas, contexts, and competencies. The characteristics of each country's assessment items developed for each content area were analyzed using the framework. We suggested some implications on developing and improving national-level academic assessment items.

The purpose of this study was to investigate the effects of 'problem posing from mathematical problems' on the students' affective domain of mathematics, and to conduct evaluation and management of teachers' respectively. The quantitative and qualitative approaches were combined to analyze the changes in the affective achievement of all the students and individual students in the study. The conclusions of this study are as follows: First, problem-posing class improved the problem-solving ability and meaningful experience in the learning activity itself, thus improving students' self-confidence, interest, value, and desire to learn. Second, The students' affective domain of mathematics should be emphasized, and systematic evaluation and management should be carried out from the first grade of middle school to high school senior in mathematics. Third, it is necessary to present and disseminate them in detail on the national-level to evaluation system and method of affective domain of mathematics. Therefore, the teacher should actively implement the problem-posing teaching and learning in the classroom lesson and help students' affective achievement. and teachers need to measure and manage the affective achievement of all students on a regular basis.

오늘날의 교육은 단순히 지식을 많이 습득하는 것보다 문제를 인식하고 지식 및 정보를 통합하여 창의적으로 문제를 해결할 수 있는 역량 중심의 교육을 강화하고 있다. 이러한 역량을 배양하고 함양하기 위해 학생들의 발달 수준을 알아보고 분석하기 위해 국제 수준의 학업 성취도 평가 연구가 국제기구를 중심으로 활발히 이루어지고 있다. 학습자들의 역량을 효과적으로 평가하기 위해 최근에 컴퓨터 기반 평가가 도입되고 있다. 본 연구에서는 국제 수준의 학업 성취도 평가에서 컴퓨터 기반 평가가 이루어지는 현황을 파악하고 PISA와 ICILS의 공개 문항의 특징을 비교하여 시사점을 제시하였다.

Metacognition is a core element for nurses' clinical competency as a result of the learner's development and evaluate goals and plans for problem solving. The study aimed to analyze factors related to metacognition among undergraduate nursing students. The 205 nursing students participated from August 15 to October 19, 2017 to measure metacognition, self-directed learning, grit, learning environment and learning style. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple regression with the SPSS/Win 22.0 program. Metacognition represented a positive correlation with self-directed learning, grit, learning environment. The self-directed learning and grit were significant factors on undergraduate nursing students' metacognition. As a result of this study, it is necessary to develop curriculum that can improve metacognition level by increasing self-directed learning ability and grit of undergraduate nursing student.
