Interest in the education for the technology entrepreneurship has increased significantly in the past decade but it is not enough for the educator. That is the reason that one educator has field experience without the theoretical background and the others have theory without the practical experience. Government ask to university to enhance the entrepreneurship training in the undergraduate and graduate level. Our study focus on the what is important for the entrepreneurship educators. Among the evolution of entrepreneurship education, this paper suggest three factors for the educators, the development of teacher and coach who has embedded entrepreneurship algorithm, teachers who has many practice and know-how, and last one is balancing and harmony teamwork of coaches and teachers.

In this paper, we introduce a web-based scheduling toolkit(GridTool2), which can run simulation of scheduling algorithm in grid system. And we suggest new algorithms which apply additional communication costs to the existing MinMin and Suffrage scheduling algorithms. Since GridTool2 runs in web environment using server and database, it does not require a separate compiler or runtime environment. The GridTool2 allows variables such as communication costs on the web for performance evaluation, and shows simulation results on the web page. The new algorithm with communication costs was tested using GridTool2 to check for performance improvements. The results revealed that the new algorithm showed better performance as more workloads were incorporated to the system.

Long division was one of the major issues in math war II started from 1990's in US. In this paper, we investigated this concretely and examined present teaching condition of long division in Korea. Firstly, Long division is not only a mechanical way to get the answer but also a realization of core conception in elementary mathematics. Futhermore it is a connecting link between elementary and middle mathematics education. Secondly, it is needed to use the term 'long division' to provide the concrete teaching guidelines. Thirdly, a minor algorithm, like an 'partial quotient method', is necessary to introduce in order to help understanding long division.

The main purpose of computing education is to teach the Computational Thinking which is based on Abstraction, Automation and etc. In Elementary and Secondary Education, programming activity is provided for the purpose of learning algorithm design. In this paper, the achievements of learning concepts of algorithm design are analyzed on the learner's characteristics in the programming activities using the Tangible programming tools for elementary and secondary school students. As a result, the achievement did not show the difference on grades but the usability showed the difference on genders.

본 논문은 화학에서 사용되는 2가지 산, 염기 모델에 대한 이해를 높이고자 각 모델의 핵심 알고리즘가 반영된 단계별 교육용 콘텐츠를 개발하는데 목적이 있다. 이를 위해 먼저 Arrhenius와 Brønsted-Lowry 모델이 갖는 핵심 알고리즘을 탐색하였으며, 이러한 핵심 알고리즘을 반영된 단계별 교육용 콘텐츠를 JAVA를 이용하여 개발하였다. 개발된 교육용 콘텐츠는 총 5단계로 구성되어 있다. 1단계는 화학에서 다루어지는 입자들이 개별적으로 무작위하게 운동함으로 표현하였으며, 2단계는 화학반응이란 이러한 무작위적 운동 중 입자 간 충돌에 의해 반응이 개시됨을 보여주었다. 3단계에서는 단일입자에 대해 정반응과 역반응을 동시에 고려한 진행되는 상황을, 4단계는 여러 입자가 동시다발적으로 정반응과 역반응에 참여한 상황을 구현하였다. 마지막 5단계는 정반응과 역반응의 공존의 비율이 다른 상황을 통해 평형상수의 의미를 고찰하도록 하였다. 창발적 사고의 핵심은 여러 입자를 생각하는 확률적 사고와 이러한 여러 입자가 개별적으로 움직인다는 사고가 반영되어야 한다. 이 연구에서 개발한 교육콘텐츠를 활용한다면 학생들이 보다 창발적 사고를 하는데 도움을 줄 것으로 기대된다.

This paper analyzes the activities for (fraction) ${\times}$(fraction) in Korean elementary textbooks focusing on the connection between visual models and the algorithm. New Korean textbook attempts a new approach to use length model (as well as rectangular area model) for developing the standard algorithm for the multiplication of fractions, $\frac{a}{b}{\times}\frac{d}{c}=\frac{a{\times}d}{b{\times}c}$. However, activities with visual models in the textbook are not well connected to the algorithm. To bridge the gap between activities with models and the algorithm, distributive strategy should be emphasized. A wealth of experience of solving problems of fraction multiplication using the distributive strategy with visual models can serve as a strong basis for developing the algorithm for the multiplication of fractions.

Many researchers have supported in various aspects that elementary students should experience alternative algorithms as well as formal standard one for addition and subtraction. Korean elementary mathematics textbooks have some units for alternative algorithms for addition and subtraction. In special, the change of unit sequence in the second grade revised mathematics textbooks may cause the necessity for discussion about teaching sequence and teaching purpose between alternative algorithms and formal standard one. Therefore, this study aims to consider the purpose of teaching alternative algorithms and to induce implications for their teaching strategies and sequence. To do this, related references, curriculum and textbooks were analyzed. Four lessons were observed and three teachers were interviewed. The main content of this study is the result of analysis on students' activities and teachers'teaching approaches. This study also includes didactical implications based on the result.

Q-Learning is a technique widely used as a basic algorithm for reinforcement learning. Q-Learning trains the agent in the direction of maximizing the reward through the greedy action that selects the largest value among the rewards of the actions that can be taken in the current state. In this paper, we studied a policy that can speed up agent training using Q-Learning in Frozen Lake 8×8 grid environment. In addition, the training results of the existing algorithm of Q-learning and the algorithm that gave the attribute 'direction' to agent movement were compared. As a result, it was analyzed that the Q-Learning policy proposed in this paper can significantly increase both the accuracy and training speed compared to the general algorithm.

2015 개정 교육과정에 따라 2019년 3월부터 초등학교 5~6학년 학생을 대상으로 소프트웨어 교육이 실시된다. 궁극적인 소프트웨어 교육의 목표는 컴퓨팅 사고력을 갖춘 창의 융합형 인재를 양성하는 것이다. 이를 위해 초등학교에서는 알고리즘과 프로그래밍의 체험을 통해 소프트웨어 기초 소양을 함양하는 것을 목표로 한다. 이러한 컴퓨팅 사고력을 수업에 효과적으로 적용하기 위해 전용주(2017)는 소프트웨어 및 컴퓨팅에 관련된 사고과정과 원리를 실생활의 소재와 관련지어 창의적이고 능동적으로 그 해결방안을 구현해가는 과정으로 제시할 수 있는 수업 구성 원리인 CT-CPS 수업 모형을 개발하였다. 또한 교육부는 2015 개정 교육과정 실시 전, 소프트웨어 교육을 위한 선도학교를 전국에 지정하여 운영하였다. 선도학교에서의 소프트웨어 교육과정을 분석한 결과 주로 컴퓨팅 사고력의 구성요소 중 알고리즘과 자동화에 초점이 맞춰져 있었다. 엔트리와 스크래치와 같은 블록 프로그래밍 도구를 사용한 코딩교육과 로봇교육을 주로 실시했고, 실제 문제에 대한 학생들이 자료를 직접 다루는 시간은 찾아보기 힘들었다. 컴퓨팅사고력 향상을 위해서는 학생들이 실제 자료를 수집, 분석, 표현해보는 활동이 반드시 필요하다. 이에 본 연구에서 NetsBlox을 활용하고자 한다. NetsBlox는 학생들에게 익숙한 블록형 프로그래밍 도구로 실제 데이터를 온라인상에서 쉽게 받아와서 수집, 분석, 표현을 하게 도와주는 역할을 한다. 따라서 본 연구에서는 초등학생을 위한 NetsBlox를 활용한 CT-CPS기반 프로그래밍 수업을 설계하고자 한다.

As technology advances, the importance of software education is increasing. Accordingly, interest in information subjects is increasing, but intending elementary learners to show algorithms only for specialized IT skills that could spoil the interest. In this paper for the elementary school students, through the four stages, 2015 revision curriculum analysis, creating of training program development operating plans, applying programs for the targeting students and analysis of results and evaluation, using Rich Picture technique which is various tools such as pictures and speech bubble symbols for the learners can express the intelligent CCTV algorithm freely and easily so they can understand fully about the algorithm of intelligent CCTV that uses artificial intelligence to extract faces from subjects. Suggest on this paper, the proposal of educational program can help the learner to grasp the principle of the algorithm by using the flowchart. As the result, Through the modification and development of the proposed program, we will conduct research on IT creative education that can be applied in various areas.
