The Ministry of Education (2015) announced the "2015 Revised Curriculum for Elementary and Secondary Schools" and announced that SW (Software) training for elementary and junior high school students to develop Computational Thinking will be gradually introduced from 2018. In addition, 'problem solving' and 'programming' have become important areas. Furthermore, the ability to analyze and utilize big data is becoming more emphasized. We developed and applied the statistical - Python programming convergence curriculum based on the idea that convergence education combining information and mathematics, programming and statistical literacy is needed according to current trends. Before and after the experiment, problem solving ability test and programming / mathematical interest test were conducted and compared with the corresponding sample t-test. According to the analysis results, there were significant differences in the pre- and post-test on problem solving ability, programming interest and mathematical interest at the significance level of 0.05.

In this paper, we implemented by describing a pipeline processor using a HDL in functional level, simulated and verified it's operation. When simulating a implemented processor. We first specify assembly instruction that is Performed in the processor. entered by programming using the instruction sets at the experimental framework. Thus, the procedure that is presented in this paper can easily identify and verify the purpose for implementation and operation of a system by using test vector. Also, it was possible that exactly simulate a system. The method was comfortable that document a system operation to implement.

Developing Computational Thinking is getting attention as the importance of SW is emphasized. Also programming education is getting attention, especially, various researches that utilize robot in programming education are being carried out. This study focused on compensating the defects of the prior robot programming education and exploring the way of utilizing web based tool 2.0 while putting emphasis on communication and cooperation. This plan is based on $Gagn{\acute{e}}$ & Briggs nine events of instruction and can be used to implement cooperative learning with the Web 2.0 based tools at every instructional events. Tests for learner's cooperation were done before and after this new plan to evaluate its value. The result proves that this plan had a positive influence on improving learner's cooperative attitude.

Metacognition is defined to be 'thinking about thinking' and 'knowing what we know and what we don't know'. It was verified that the metacognitive abilities of high school students can be improved via instruction. The purpose of this article is to investigate a new method for activating the metacognitive abilities that play a key role in the Mathematical Problem Solving Process(MPSP). Hyunsung participated in the MPSP using Visual Basic Programming. He actively participated in the MPSP. There are sufficient evidences about activating the metacognitive abilities via the activity processes and interviews. In solving mathematical problems, he had basic metacognitive abilities in the stage of understanding mathematical problems; through the experiments, he further developed his metacognitive abilities and successfully transferred them to general mathematical problem solving.

본 연구에서는 21세기 지식정보사회에 학생들의 창의력 향상을 위하여 MSRDS에서 제공하는 에디터인 VPL(Visual Programming Language)를 이용한 로봇 프로그래밍 학습이 창의력에 미치는 효과를 연구하였다. VPL은 로봇 애플리케이션 개발을 프로그래머가 아닌 학생들도 쉽게 사용할 수 있도록 MSRDS에서 제공하는 프로그램이며, 이를 시뮬레이션과 연결시켜 로봇 하드웨어가 없이 손쉽게 학습을 할 수 있게 하였다. 이를 위하여 VPL에서 사용하는 기본 Activity를 이용하여 프로그래밍의 구문을 자연스럽게 학습할 수 있는 수업 내용을 개발하였으며, 연구 대상은 충청남도 B군에 위치한 B공고 3학년의 컴퓨터응용관련 학과 1개반을 대상으로 C언어를 이용한 기존의 마이크로 장비 프로그래밍 수업과 VPL을 이용한 로봇 프로그래밍 수업을 상호 비교하려고 한다. 이 연구에서는 VPL을 통하여 손 쉽게 프로그래밍을 하고 흥미가 유발되어 자신이 생각한 대로 로봇의 동작을 구현하는 과정에서 자연스럽게 문제해결능력이 신장된 것을 확인하고자 한다.

With the rapid growth of the Web technologies, the Web has changed teaching and learning as well as our life in various ways. Web-based instruction (WBI) supports self-directed and creative learning at anytime anywhere. However, learners may experience the problems of disorientation and cognitive overload when the hyperspace that consists of learning materials is complex. In this paper, we present a Web-based adaptive hypermedia system based on cognitive load theory which can reduce cognitive loads that novices may experience when they learn programming

This paper proposes a machine vision module for PLCs (Programmable Logic Controllers). PLC is the industrial controller most widely used in factory automation system. However most of the machine vision systems are based on PC (Personal Computer). The machine vision system embedded in PLC is required to reduce the cost and improve the convenience of implementation. In this paper, we newly propose a machine vision module based on PLC. The image processing libraries are implemented and integrated with the PLC programming tool. In order to interface the libraries with ladder programming, the ladder instruction set was also designed for each vision library. By use of the developed system, PLC users can implement vision systems easily by ladder programming. The developed system was applied to sample inspection system to verify the performance. The experimental results show that the proposed system can reduce the cost of installing as well as increase the ease-of-implementation.

Today, living in a software-centered global community. lots of countries are putting most efforts on breeding a creative manpower well equipped with problem-solving abilities based on computational thinking. Upon this colleges and universities where most strongly related to job activities are proceeding instruction related to programming for the IT majors realizing the importance of the software education. Hereby we intend to be of a proper help for every colleges and universities students who are working on educational programming design for the first time performing a research probing the relationship with the full gamut of computational thinking based on the result acquired through a phased survey showing the amount of difficulties at their beginning stages.

In this paper, we have selected physical computing as the focused learning elements with the PBL-based programming instruction method. Students experienced physical computing by using Arduino. Development of robot using Arduino can create an effective educational environment and also provide solutions for lack of environmental conditions, such as time or spatial factor restrictions and excessive expense issues; these are major obstacles to developing robot programming education. Finally, we analyzed the effects on growth of student's logical thinking and problem solving abilities by demonstrating the Arduino application courseware to the field of education.
