Small Group Collaborative Instruction in school settings has been endorsed by many educational experts over the years. Some studies found that learners greatly benefit from one another through communication and interaction with their peers. These studies previously indicated improvement of a learner‘s academic ability as well as the application of the affective domain when using this type of instruction. Lower-level students with limited mathematical abilities improved their problem-solving and conceptual thinking skills when tasked to work with other learners. On the other hand, the effectiveness of this process was questioned to be less evident with higher-level performers. Therefore, this study was designed to observe the efficacy of Small Group Collaborative Instruction on higher-level students and to explore their learning process as they interact with and teach lower-level students. This study observed that higher-level students use high-level mathematical thinking skills when helping lower-level students, and they improved problem-solving ability as well as communication skills.

Modern society needs to think in new directions and solve problems by grafting problems from diverse fields with computers. Abstraction and automation of various problems using computing technology with your own ideas is called computational thinking. In this paper, we analyze how to diagnose and improve knowledge information based on computational thinking through the process of presenting a variety of problems in programming education situations and finding several problem-solving methods to solve them. To pretest the learners, they were diagnosed using a measurement sheet and a LightBot. By determining the correlation between the evaluation results and LightBot results, the learners' current knowledge statuses were checked, and the correlation between the evaluation results and the LightBot results, based on what was taught according to the problem-solving learning technique, was analyzed according to the proposed technique. The analysis of the group average score of the learners showed that the learning effect was significant. If the method of deriving and improving knowledge based on computational thinking ability for solving the problem proposed in this paper is applied to software education, it will induce student interest, thereby increasing the learning effect.

프로그래밍은 문제해결의 한 유형으로 학습자의 인지기술과 논리적 사고력을 향상시킬 수 있다. 컴퓨터 교육에 있어서 프로그래밍 교육이 중요한 위치를 차지해야 함에도 불구하고 초등학교에서는 거의 지도가 되지 않고 있다. 이에 본 연구는 구성주의적 교육 도구로써 많은 장점을 지닌 Lego Dacta를 이용하여 초등학생들이 쉽고, 즐겁게 프로그래밍을 할 수 있는 수업모형을 제시하고자 한다. 다양한 문제를 통한 단계적 문제 해결과정으로써의 Lego Dacta 학습모형을 제시하여 학교현장에서 적용할 수 있는 방안을 분석하였다.

The purpose of the study was to compare the effects of two instructional methods, which were the instructor-led instruction and the simulation delivery instruction on students' well-structured and ill-structured problem solving performance and motivation. 29 undergraduate students participated in the study and repeated measure design was used. We found significant difference of means in ill-structured problem solving performance and only relevance scale in motivation.

This study aims to suggest an instructional design to improve CT(Computational Thinking) skills in terms of problem solving. CT can be defined as a thought processes for computer-based problem solving. Examining the related CT concepts in the general problem solving process can be helpful for learners to understand CT. For this, this study selects the key elements of CT through literature review, describes how the elements are related to each phrase of the problem solving process, and explores cognitive aspects of the CT elements. In addition, this study describes learning activities and learning assessments of the CT elements according to each phrase of problem solving process and suggests a basic instructional design framework for CT in view of problem solving.

To help programming learning, we have designed a robot programming course that improves complex cognitive abilities. The developed course was implemented in college programming classes and educational effects were analysed. While students are learning through LEGO Mindstorms NXT and NXT-G software, the students' problem solving abilities have been enhanced. The developed robot programming course gives positive effects on learners' problem solving abilities. It means that the developed course helps a learner in a cognitive domain.

The purpose of this study is to investigate the effect of simulation practice combining problem-based learning on nursing knowledge, self-confidence, critical thinking tendency and problem solving ability. The subjects of this study were 45 students who took two courses of nursing situation practice in the fourth grade of S university in S area. Data were collected before and after the simulation exercise using the self-report questionnaire. The problem-based learning and the simulation practice convergence training were conducted for three weeks with two hours per week, and the post- integration nursing knowledge, self-confidence, critical thinking disposition, and problem solving ability scores were improved. Nursing knowledge, self-confidence, and critical thinking tendency were positively correlated with problem solving ability and proved the effectiveness of problem-based learning and simulation training. Therefore, education programs combining problem-based learning and simulation training on various topics should be developed and utilized.

Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

일선 교육 현장에서 영재를 지도함에 있어서 해결해야 할 당면 과제는 판별 도구와 학습 프로그램의 개발이다. 영재를 위한 수학 프로그램을 문제 해결형, 수학 탐구형, 과제 해결형의 3가지로 분류할 경우, 퍼즐은 문제 해결형과 수학 탐구형 프로그램의 특성을 공통적으로 갖고 있는 유형으로 수학적 지식의 통합과 연결성. 그리고 창의적 문제 해결력 신장 및 수학적 원리 ${\cdot}$ 법칙을 체험적으로 만들 수 있는 기회를 제공한다는 점에서 매우 가치있는 프로그램이다. 특히 조작퍼즐은 기존의 대수적 표현 체계로 학습하기가 힘든 관찰력이나 공간에 대한 인식과 표현력 친 공간 추론력을 기르는 데 유용하며, 게임적인 요소가 포함된 퍼즐은 지필에 의존해 왔던 수학학습에 대한 부정적인 인식을 해소하는 데 크게 기여할 것이다. 본 고에서는 수학 퍼즐의 종류 및 특성과 교육적 가치에 대해서 개괄적으로 살펴보고, 실제 프로그램 작성을 위한 정보를 제공과 영재들의 공감 감각을 기르기 위한 프로그램의 원을 이용한 수학 퍼즐의 개요를 제시한다.

This study investigated the definition and characteristics of computer science problem to be solved through computational thinking. It also explored types and cases of both computer science problems and teaching learning methods to solve computer science problems. Before studying computer science problems, I examined the definition, type, and the importance of problem solving in other subjects. Based on this research, We found that informatics can solve ill-structured problems through computational thinking and the power of computing. This includes counting, decision, retrieval, and optimization problems. Teachers can improve their students' skills in computational thinking, particularly as related to abstraction, automation, and generalization, by choosing the appropriate teaching and learning method or based on the characteristics of the problem.
