본 연구의 목적은 실제 상황에서 수업과 통합된 형태로 이루어지는 수학교육의 교수-학습 참평가 모형과 예시 도구를 개발하는 것이다. 이를 위해 문헌연구를 통하여 수학교육에서의 참평가를 정의하고, 참평가 과제 준거와 진정한 수학적 활동이 무엇인지 살펴보았다. 참평가 수업설계 모형으로는 상황인지 수업설계 모형, 수학과 교수-학습 평가 모형, 프로젝트 평가 절차 모형을 살펴보았다. 프로젝트법을 적용한 수학과 참평가 과제 개발은 수학과 프로젝트의 유형인 실생활 문제해결형, 타교과 연계형, 수학사 활용형, 신문활용 교육형, 수학적 모델링형, 주제탐구형을 택하여, 수학과 참평가 과제 준거에 맞는 내용으로 선정하였다. 개발한 과제는 수학교육전문가에게 내용타당도를 의뢰하였고, 평가기준의 적절성을 검증받았다. 개발한 수학교육의 교수-학습 참평가 모형과 예시도구는 고등학교 학생들에게 적용해 봄으로써 학생 반응 결과와 시사점을 도출하였다. 그 결과 개발한 수학교육의 교수-학습 참평가 모형과 예시 도구는 수학교육에서 참평가를 실시하는데 의미있게 사용되어질 수 있는 것으로 여겨진다.

테크놀로지 내용교수지식(TPACK)은 1986년 Shulman이 제시한 내용교수지식(PCK)에 테크놀로지 지식이 통합된 새로운 지식 즉, 교사의 내용지식(CK), 교수학적 지식(PK), 테크놀로지 지식(TK)의 교집합에 해당하는 지식을 뜻한다. 본 연구에서는 2009년 1학기 서울시 소재 사범대학에서 팀 프로젝트를 중심으로 하는 테크놀로지 강의를 개설하고 설계, 분석하여 예비 수학교사의 TPACK 신장을 위한 방안을 모색하고자 하였다. 강의 초 예비 수학교사들은 테크놀로지에 대해 낮은 자신감을 나타냈지만, 강의가 끝날 무렵의 테크놀로지 관련 수학교수효능감은 3.88부터 4.50사이로 높게 나타났다. 또한, 예비 수학교사들은 팀 프로젝트가 TPACK에 긍정적 또는 매우 긍정적인 영향을 주었다고 응답했는데, 이는 팀 프로젝트를 중심으로 하는 테크놀로지 강의가 예비 수학교사가 앞으로 교사가 되어 테크놀로지를 활용하는 수업을 설계할 때 필요한 지식과 자신감을 갖도록 하는 데 효과적인 방법이 될 수 있음을 보여준다. 교사의 TPACK이 정보화 시대의 교육과정에서 제시하는 교육목표 달성을 위해 필수적인 지식이라 볼 때, 앞으로 예비 교사를 대상으로 하는 테크놀로지 강의가 테크놀로지의 사용 방법과 단편적인 적용 사례를 전달하는 방식보다 테크놀로지 활용 수업을 계획하고 설계하는 방식으로 변화되는 것이 바람직할 것으로 보인다.

The purpose of this study is to device the teaching-learning method and the evaluating method on 'free inquiry' which is newly introduced in 2007 revised curriculum. The teaching-learning models which apply 'free inquiry' are 'group investigation', 'PBL', 'project investigation' and 'IIM'. And the unit which apply 'free inquiry' on the fourth grade and the second semester in the elementary science. The results of this study are as follows: First, The person leading the lesson is not a teacher but learners. The focus of teaching-learning is not a unit but topic, problem or project on the science textbook. A teacher's role is not the deliverer of knowledge but the guide of learning. Second, the outcome of applying group investigation, PBL project investigation and IIM to 'free inquiry' is improvements of the problem-solving ability and the self-directed learning ability as well as building scientific attitude and social skills as educational effect in commonly. Third, to apply 'free inquiry' efficiently, teachers should understand each subject very well, teach a class with a thorough and concrete plan, and try to evaluate objectively.

This article is to investigate the possibility that project-based classes introducing mobile phones can replace the monotony of traditional classes led by teachers as well as they can encourage students to take active part in the classes to some extent. The students in groups choose a genre for their own video projects (e.g., movie, drama, news, documentary, and commercial) and produce the video contents using a mobile phone for presentation made at the end of a semester. In the sense that the students are allowed to do video-based mobile phone projects, they can work independently outside of class, where time and space are more flexible and students are free from the anxiety of speaking or acting in front of an audience. A mobile phone project consists of around five stages done both in and outside of the classroom. All of these stages can be graded independently, including genre selection, drafting of scripts, peer review and revision, rehearsals, and presentation of the video. Feedback is given to students. After the presentation, students filled out a survey questionnaire sheet devised to analyze students' responses toward preferences and level of difficulty of the project activity. Finally, proposals are made for introduction of a better mobile phone-based project classes.

The Korea Astronomy and Space Science Institute (KASI) is developing three 1.6m optical telescopes with $18k{\times}18k$ mosaic CCD cameras. These telescopes will be installed and operated at Chile, South Africa, and Australia for Korea Micro-lensing Telescope Network (KMTNet) project. The main scientific goal of the project is to discover earth-like extra-solar planets using the gravitational micro-lensing technique. To achieve the goal, each telescope at three sites will continuously monitor the specific region of Galactic bulge with 2.5 minute cadence for five years. Assuming 12 hour observation in maximum for a night, the amount of 200 GB file storage is required for one night observation at one observatory. If we consider the whole project period and the data processing procedure, a few PB class data storage, high-speed network, and high performance computers are essential. In this presentation, we introduce the KMTNet data management plan that handles gigantic data; raw image collecting, image processing, photometry pipeline, database archiving, and backup.

Recently, the demand to interpret image data with artificial intelligence in various fields is rapidly increasing. Object recognition and detection techniques using deep learning are mainly used, and video integration analysis to determine unstructured object recognition is a particularly important problem. In the case of natural disasters or social disasters, there is a limit to the object recognition structure alone because it has an unstructured shape. In this paper, we propose intelligent video integration analysis system that can recognize unstructured objects based on video turning point and object detection. We also introduce a method to apply and evaluate object recognition using virtual augmented images from 2D to 3D through GAN.

As the definition and role of design changes over time with the times and society, design education needs to update teaching methods to match it. The course design in this study began with an optimisation of the learning model based on previous research and analysis, followed by in-depth interviews, the application of the interview results to the final curriculum design, and finally a questionnaire to verify the positive effects of this teaching model. This teaching model has been applied to teach a pilot class in a university of applied sciences in China. The main characteristics of the course design are Project-Based Learning (PJBL) oriented, team cooperation centric, and an educational model developed based on peer assessment. In every stage of the UI design course, realistic project simulations are adopted, enhancing students' abilities through practical experience, teamwork, and peer assessment. The innovation lies in validating the effectiveness and advantages of this model at every stage of the UI design course, innovating existing teaching methods, optimizing learning models, and combining practice with evaluation. This research found that a project-oriented team course design based on PJBL has a high degree of effectiveness and relevance in each stage of the UI design course, significantly improving students' overall competence. It is expected that the results of this study can be applied in various ways to the course design of the courses that similar to design majors.
