  • The purpose of this study was to analyze of the science examination of middle school 7th grade by Klopfer's taxonomy of educational objectives. A total of 645 test items from 10 middle schools were analyzed for this study. The examination items were analyzed according to the objectives of science education, such as behavior and contents area, question types, and the degree of difficulty. It was shown that, when the distribution of behavioral objectives was considered, the items emphasized knowledge and comprehension, and were scientific knowledge oriented. The tests consisted of multiple choice questions at a relatively high rate, compared to short answer questions. Comparing the rate of teachers' expectations to the degree of difficulty, the ratio of "top" was low and that of "medium" was high. The results of this study suggested that using various types of question and multiple levels of content and behavior enabled more effective evaluation of the diverse thinking powers and learning of the students.

  • PURPOSE: This study aims to provide basic materials to re-establish terms and to build the institutional framework for the home and visiting physical therapy. METHODS: For such purpose of the study conducted the research that targeted the physical therapists, who were working at the rehabilitation hospital located in Gyeonggi-do as for the survey questionnaires as to the need and awareness of development of the adequate insurance fee of home physical therapy and visiting physical therapy. RESULTS: The survey result shows the awareness is low on the term separation in referring the home physical therapy and the visiting physical therapy. On the question regarding the performance obligation in the current system of the home and the visiting physical therapies, the answers for the recognition are shown to be 58% and 88.1% while no significant differences according to ages and working periods are found in all questions (p>.05). In the meanwhile, on the question regarding necessities of the home and the visiting physical therapies, answers agreeing the necessity is shown as 96.3%. And, on the question regarding the expected effect, the score shows to be very high with 40.5 points out of 50 points and significant differences according to the age and the working period (p<.05). CONCLUSION: It directly reflects the result, as the age and the working period are longer, the necessity shows to be higher.

  • The research area for solving question answering (QA) problems using artificial intelligence models is in a methodological transition period, and one such architecture, the dynamic memory network (DMN), is drawing attention for two key attributes: its attention mechanism defined by neural network operations and its modular architecture imitating cognition processes during QA of human. In this paper, we increased accuracy of the inferred answers, by adapting an automatic data augmentation method for lacking amount of training data, and by improving the ability of time perception. The experimental results showed that in the 1K-bAbI tasks, the modified DMN achieves 89.21% accuracy and passes twelve tasks which is 13.58% higher with passing four more tasks, as compared with one implementation of DMN. Additionally, DMN's word embedding vectors form strong clusters after training. Moreover, the number of episodic passes and that of supporting facts shows direct correlation, which affects the performance significantly.

  • This study examined the difference in the item characteristics in multiple-choice aptitude tests focusing on the response position, response length and question types. A university aptitude test consisting of 80 questions was used for this study. The subjects were 3120 senior high school students from 80 schools nation-wide (liberal arts-1650, natural sciences-1467 patients). The results suggest that item prediction is higher for numbers 2 and 3 (located in the middle) than numbers 1 and 4. The item discrimination was higher for pick-the-'wrong'-items than pick-the-'right'-items. In addition, longer choices are preferred. The suggestions for future research are provided based on these findings.

  • For the questions asked for LMS-based online evaluation the professor directly set exam questions, or use the automatic question-taking method according to the level of difficulty using the question bank divided by category. Among them, it is important to manage the difficulty of questions in an objective and efficient way, above all, in the automatic question-taking method according to difficulty. Because the questions presented to the evaluators may be different. In this paper, we propose an difficulty re-adjustment algorithm that considers not only the correct rate of a problem but also the time taken to solve the problem. For this, a logistic regression classification algorithm was used of machine learning, and a reference threshold was set based on the predicted probability value of the learning model and used to readjust the difficulty of each item. As a result, it was confirmed that there were many changes in the difficulty of each item that depended only on the existing correct rate. Also, as a result of performing group evaluation using the adjustment difficulty problem, it was confirmed that the average score improved in most groups compared to the difficulty problem based on the percentage of correct answers.

  • This study conducted a preliminary survey to study humanities healing methods for college students. Based on the student survey, we would like to present the research direction of humanities healing and find an appropriate humanities healing method. For quantitative analysis, 10 questions were constructed, focusing on BPS-Modell, Bio, Psycho, and Sozio of life. In the question of the Bio, 50% of the students said they understood their body, mind, and will and acted accordingly, but 20% of the students showed that their actions according to their body, mind, and will did not fit. In the question of Psycho, more than 50% of students said they communicated well with their inner selves, but less than 20% of students did not. In the question of Sozio of life, more than 60% of students form a social network well, but about 10% of students have very low attitudes or meanings toward life. The ultimate purpose of humanities is 'happiness', and the purpose of human life is also 'happiness'. We hope that the power of positivity to realize a stable future society and improve the quality of life will be expanded through humanities healing.

  • The Ministry of Agriculture and Forestry announced promoting the project, 'Regional Agricultural Clusters,' in Feb. 2004 through 「The Comprehensive Plan for the Agriculture and Agricultural Communities」 and initiated a model project from 2005. The purpose of 'Regional Agricultural Clusters' is to develop regional agriculture by concentrating the resources and capacities of the region and maximizing the effect of integrating related projects. 31 towns in Geonggi and 2 towns (Ganghwa and Ongjin) in Incheon were chosen for the study based on the crop areas of 36 agricultural products from the Agricultural Census in 2000. For those 33 towns, factors such as the top 20 agricultural products, main producing districts and surveys on each towns were considered and we have concluded that these items are good subjects for 'Regional Agricultural Clusters' : We have decided on 18 items for what we call, 'Mini-Clusters,' a cluster in which the item's main producing district is in only one area of the town in question (in 30 projects out of 21 towns). Secondly, we have decided on 11 items for what we call, 'Base-Clusters,' a cluster in which the item's main producing district can be associated by name with the item, the production is sizeable, and can be found in several locations of the town in question (in 13 projects out of 11 towns). Finally, we have decided on 12 items for what we call, 'Broad-Based-Clusters, a cluster which the item's main producing district expands the past the vicinity of the town in question (in 19 projects out of 19 towns).

  • The purpose of this study is to analyze the teaching of statistical graphs according to elementary mathematics curriculum. To do this, we set up three research questions as follows. First, what is the change in achievement standards related to the teaching of statistical graphs in elementary mathematics curriculum? Second, what is the change in the teaching of the drawing of statistical graphs in elementary mathematics curriculum? Third, what is the change in the teaching of understanding of statistical graphs in elementary mathematics curriculum? For the first research question, we analyzed the achievement standards related to the teaching of the statistics of the 2015 revised curriculum from the first curriculum. For the second research question, we analyzed how to provide students with the opportunity to draw graphs(number of drawings) and whether to present the basic frame of the graphs(frame provided). For the third research question, we analyzed questions in the textbooks based on the graph understanding; 'reading data', 'finding the relation between data', 'interpreting data', 'understanding the situation'. As a result of the analysis, the achievement standard in the curriculum has changed in the direction of fostering statistical thinking, and it has been changed to emphasize the interpretation of the graph so as to make the graph drawing easy. However, 'interpreting data' and 'understanding the situation' were still lacking.

  • This paper explores students' question generation process and their study in small group discussion. The research is based on Anthropological Theory of the Didactic developed by Chevallard. He argues that the savior (knowledge) we are dealing with at school is based on a paradigm that we prevail over whether we 'learn' or 'study' socially. In other words, we haven't provided students with autonomous research and learning opportunities under 'the dominant paradigm of visiting works'. As an alternative, he suggests that we should move on to a new didactic paradigm for 'questioning the world a question', and proposes the Study and Research Courses (SRC) as its pedagogical structure. This study explores the SRC structure of small group activities in solving ill-structured problems. In order to explore the SRC structure generated in the small group discussion, one middle school teacher and 7 middle school students participated in this study. The students were divided into two groups with 4 students and 3 students. The teacher conducted the lesson with ill-structured problems provided by researchers. We collected students' presentation materials and classroom video records, and then analyzed based on SRC structure. As a result, we have identified that students were able to focus on the valuable information they needed to explore. We found that the nature of the questions generated by students focused on details more than the whole of the problem. In the SRC course, we also found pattern of a small group discussion. In other words, they generated questions relatively personally, but sought answer cooperatively. This study identified the possibility of SRC as a tool to provide a holistic learning mode of small group discussions in small class, which bring about future mathematics classrooms. This study is meaningful to investigate how students develop their own mathematical inquiry process through self-directed learning, learner-specific curriculum are emphasized and the paradigm shift is required.
