This study is to establish the domains and the standards of instructional evaluation on the teacher knowledge dealing with the knowledge of 'teaching and learning methods and assessment'. Especially, in this study, the instruction assessment standards are developed focused on the six types of mathematics competencies such as problem solving, communication, reasoning, creativity and collaboration, information and handling, attitude and practice which were emphasized in the mathematical curriculum revised in 2015. By the result, seventh evaluation domains such as an instruction involving problem-solving activity, an instruction involving reasoning activity, instruction involving communication activity, instruction on information and handling activity, instruction involving learners' achievement level and attitude, instruction involving the development of assessment method and tool, instruction applying on assessment result were new established. According to those domains, the 19 instructional evaluation standards were developed totally. This study is limited to consider the domain of 'teaching and learning methods and assessment' among the domains of teacher knowledge, while dealing with the elements of mathematics competencies in the standards. However, instructional evaluation standards reflecting these competencies should be developed in the other diverse domains of teacher knowledge.

To improve educational performance by analyzing the learning trends of adult learners of Open High Schools, various algorithm models using artificial intelligence were designed and performance was evaluated by applying them to real data. We analyzed Log data of 115 adult learners in the cyber education system of Open High Schools. Most adult learners of Open High Schools learned more than recommended learning time, but at the end of the semester, the actual learning time was significantly reduced compared to the recommended learning time. In the second half of learning, the participation rate of VODs, formation assessments, and learning activities also decreased. Therefore, in order to improve educational performance, learning time should be supported to continue in the second half. In the latter half, we developed an artificial intelligence algorithm models using Tensorflow to predict learning time by data they started taking the course. As a result, when using CNN(Convolutional Neural Network) model to predict single or multiple outputs, the mean-absolute-error is lowest compared to other models.

The purposes of the study are to introduce and apply an activity that can help improve student-initiated learning on the TOEIC Speaking Test (TOEICST) performance and to see students' attitude toward the activity. Twenty-eight university students in Chungcheong province engaged in learning based on this activity. In the present study, the activity proposed by McCormick and Vercellotti (2013) and Stillwell, Curabba, Alexander, Kidd, Kim, Stone, & Wyle (2010) was modified and adapted[14][19]. The outline of the Task Recording Activity (TRA) consisted of three steps: preparation step, Task Recording Activity step, and evaluation step. As data collection of the study, a survey and students' journal were utilized and qualitatively analyzed. The results showed that student-initiated learning activity could be applied positively not only in communicative lessons, but in TOEICST specific lessons as well. Additionally, participants showed positive attitudes toward self-transcription and self-correction. Some implications of the study are that the TRA can be applied to generate autonomous learners studying for the TOEIC Speaking Test, that the guideline for different proficiency can be developed to help them improve their self-reflection, and that students need to have an active attitude to lead their own learning.

전통적인 수학교육은 간단한 수학적 사실을 이해하고 활용하는 측면에 있어서는 효과적일 수도 있지만, 수학적 개념, 원리, 법칙을 학생 스스로 탐구, 발견하고 창조하는 능력을 기르는 데는 적절하지 않다. 이러한 능력을 기르기 위해서는 학생들 스스로가 관찰, 조작, 분석, 종합하는 활동을 강화할 필요가 있다. 구체적 조작물을 학습도구로 활용하는 경우, 수학 학습에 대한 흥미와 자신감을 길러 주고, 자신의 수준에 맞는 내용을 자기 주도적 학습을 통하여 성취감을 가지게 하며, 학생 스스로 탐구 활동을 활발히 하는데 도움이 된다. 삶의 질이 급격히 향상되는 정보사회에서는 사이버 공간의 등장으로 공간감각 기능의 필요성이 더욱 절실한 바, 현행 수학교과서에서 제공되는 각종 공간 도형들은 3차원 공간에서 이루어지지 않고 평면도형으로 처리함으로써 아동의 도형인지 능력 향상에 큰 효과를 기대하기 어렵다. 이에 본 연구에서는 아동의 인지발달 단계를 고려, 도형인지능력 향상을 위한 선 및 점대칭 관련 동기유발, 선수, 기본, 보충, 심화, 평가, 도움말 관련 프로그램을 개발, 적용한 결과 학습자의 동기가 유발되고, 도형 인지능력 향상에 유의미한 결과를 얻었다.

This study investigated the current status and problems of medical librarian qualification system and measured medical librarians' self-efficacy and self-esteem. 49.4% of the respondents acquired medical librarian qualification and 82.9% of them are willing to re-acquire the qualification. To obtain publishing activity point was the most difficult of all evaluation items. Average self-efficacy score was 3.42, and self-esteem score was 3.89, and women's self-efficacy and self-esteem scores are higher than those of men. Medical librarian qualification system has been managed in a stable manner, yet the system has to be consolidated and developed into a national qualification system so that it can contribute to the improvements in proficiency of medical librarians.

Speaking skill is an important quality in expressing oneself in school life. Quite a few students experience difficulties at school because of the lack of adequate speaking ability. In order to help them, a Web-based speaking enhancement system is designed and developed using computers equipped with multimedia devices with which students can practice speaking while they are observing graphical representation of voices, which is to cause interest and voluntary participation in the learning activity. The learning system was tested on a group of 44 students of 4th grade in an elementary school. The students were divided into three smaller groups in terms of speaking ability. The experiment shows the effectiveness of the system in building speaking ability.

The purpose of this study is to reveal what mathematics teachers focus on and how they assess students' thinking during lessons enacted. For this purpose, we googled and searched internet sites to collect formative assessment materials for the year 2014 to 2019. The formative assessment tasks data were analyzed according to the levels cognitive demand levels and tasks suggested in textbooks in terms of degrees to which how they are related. The data analysis suggested as follows: a) most of the formative assessment tasks were at the low-level, in particular, PNC level tasks that require applying particular procedures without connections to concepts and meaning underlying the procedures, b) the assessment tasks appeared to be very similar to the tasks suggested in the secondary mathematics textbooks, and c) it seemed that 3 types of formative assessment, observation notes, self-assessment, and peer-assessment were dominantly utilized during mathematics lessons and these different types of formative assessment were employed apparently to find out whether students participated actively in class and in group activity, not how they go through understanding or thinking processes.

The purpose of this study was to evaluate the tobacco cessation activities of the dental staffs in Wonju city. All 137 subjects were surveyed by structured questionnaire with convenience sampling. The distribution and correlation of attitude, behavior, and intervention were evaluated by both frequency test and ANOVA test. 75.2% of total subjects responded that the dental staff should give a model through prohibition of smoking and 66.5% responded that tobacco cessation activities should be responsibility of the dental staff. Tobacco cessation counsel was performed by little but with positive attitude. Advice method of tobacco cessation was used to counsel on tobacco cessation (68.6%). The dentists (48.2%) and dental hygienists (23.4%) were responded adequate for the tobacco cessation counselor, however, it was shown that the dentist had lower level of attitude about tobacco cessation than dental hygienist (p<0.01). The dental staff needs to participate in the tobacco cessation counseling program more regularly and actively. In order for the dental staffs gets the counsel effectively and intervene with tobacco cessation, it is essential that the education of tobacco cessation is integrated in dental school. Furthermore, it is necessary for the dental staffs to take continuing education for more effective understanding of tobacco cessation.

Social networking sites (SNS), such as Facebook, provide abundant social comparison opportunities. Given the widespread use of SNSs, the purpose of the present study was to examine the impact of exposure to social media-based social comparison on user's negative emotions and discontinuous use intention on SNS. We present evidence that under the use of SNS, social comparison activities diverge into three patterns, with explicit self-evaluation desire made against similar target (lateral comparison), self-defense desire made against less fortunate target (downward comparison), and self-enhancement desire made with more fortunate target (upward comparison). Such social comparison processes frequently arise, as people are increasingly using on SNSs, the downward contacts ameliorating self-esteem with positive emotions, but the upward contacts and standard contacts with lateral status enabling a person to compare his or her situation with others and simultaneously increase negative emotions due to its differences with others. In other words, as people increasingly relying on SNSs for a variety of everyday tasks, they risk overexposure to upward or standard social comparison information that may have a cumulative detrimental impact on future intention on SNS use. This study with survey with 209 SNS users found that these negative emotions lead to negative fatigue (attitude) and then discontinuous use intention (behavior) on SNS. Our findings are among the first to explicitly examine discontinuous use intention on SNS using social comparison theory and our results are consistent with those of past research showing that upward social comparisons can be detrimental.
