Since the emergence of the artificial intelligence platform called Chat GPT, interest in the use of AI in education has been further amplified. However, AI-based learning support systems that can be employed in university education are very limited. Therefore, this research aims to develop a Teaching-Learning support model for utilizing AI-based learning assistance systems in universities. The derived Teaching-Learning support model is structured around the processes of 'Analysis and Design (pre-class)', 'Implementation (during class)', and 'Assessment (post-class)', reflecting the stages of Teaching-Learning interaction. In the Analysis and Design phase, it is categorized into individual and student group diagnosis. In the Implementation phase, it is categorized into data-driven course design and problem-solving oriented teaching. Finally, the 'Assessment' phase presents evaluation of both learners and the course (program). The presented model underwent modifications and improvements through expert validation.

In this study, instructional design strategies were developed and examined by class type for synchronous online classes to teach and learn effectively at the college courses. To facilitate effective teaching and learning in online classes at college level, a case study was conducted to explore instructional design strategies by class type as follows. Eight courses were selected at S University in Seoul during the first semester of 2020. The classes were categorized according to lesson type, class scale, pre-learning materials, and pre-tasks. Practical classes were also divided based on training tools. Applying these criteria, eight courses were classified as follows: 1) teacher-centered large classes that do not require pre-learning 2) teacher-centered small and medium-sized classes with pre-learning materials 3) discussion-based small and medium-sized classes that do not require pre-learning 4) discussion-based small and medium-sized classes that requires pre-learning, and 5) practice-based small and medium-sized classes with pre-learning materials that use software programs. For each category, instructional design strategies were developed using available tools and functions for the period before, during, and after class. Our results showed that, to ensure the interactivity in online synchronous instruction, it is necessary to apply teaching and learning support tools that are optimal for each class type. Significantly, this study provides specific instructional design strategies, and employs a variety of teaching and learning support tools for synchronous online instruction according to class type in college courses.

In this study, the research trend of educational use of artificial intelligence chatbots were systematically analyzed to identify current issues and explore future directions based on activity theory. 34 papers were analyzed by using the activity system model as an analysis framework. The results are as follows. Research on chatbots has been sharply increased from 2019 in both domestic and international. For the number of learners, above of college students were the most in both domestically and internationally. The most common sample size was 50 or less in domestic and more than 100 in foreign countries. Artificial intelligence chatbots were most often used as a purpose-based system, text-based, learning tools in both domestic and abroad. chatbots were developed for using in foreign countries, while existing chatbots were used in Korea. In both domestic and foreign countries, chatbots were aimed to teach English and intellectual skill. The most result of learning is cognitive and affective domain in Korea and affective domain in foreign conturies. The most number of use was only once in Korea and twice in foreign countries. In both domestic and foreign countries, it was the most common case that the instructor were in control of environment and offered scaffolding while using chatbots. As for the learning environment, offline was the most common in Korea, and both online and offline were identically common in foreign countries. Chatbots were not used in cooperative learning at all abroad and only one case in Korea. Based on the results, the direction of future research is presented as follows. First, a follow-up study is required to develop a task-oriented, purpose-built chatbot and strictly verify its effectiveness. Second, it is necessary to develop chatbots that support the affective domain as agents. Third, it needs to design the cooperative learning in which chatbots function as tutors and provide timely feedback. Finally, research on learning design that can effectively use chatbots by utilizing learning analysis data on online learning environment is required.

As coding education is getting more attention in and outside of school, the number of learners starting coding education is steadily increasing. However, beginners tend to struggle to resolve error messages or give up on solving the problems, resulting in learning failure. To address the issue, this study aims to develop a web-based learning support tool using AI(Artificial Intelligence) chatbot in coding education, carry out usability tests, and explore the potential effectiveness of the developed tool. The study applied the design and development method. The early prototype was developed based on the design principles derived from the literature review and case analysis. Then, six beginners participated in usability tests on the early prototype. The participants’ perceptions of the usability, ease of use, and attitude on the prototype were positive. In specific, AI chatbots’ step-by-step feedback, prompt support for problem-solving, and communication function with co-learners were found to be the advantages of the prototype. On the other hand, the needs for improvement on code description and chatbot added menu, voice recognition, and designed friendly were reported. The final prototype reflecting the improvements consisted of seven elements: ‘file’, ‘edit’, ‘view’, ‘execution’, ‘debugging’, ‘help’, and ‘support functions’. The support functions included ‘chatbot’, ‘chat room’, and ‘function description’. Based on these results, we discussed that a learning support tool that students can ask for help and receive feedback without temporal and spatial constraints is needed in order to prevent dropout students and support coding education effectively. Moreover, it is necessary to promote computational thinking by providing personalized and step-by-step feedback.

The purpose of this study is to understand how interactions are performed in cooperative learning according to academic achievement. To analyze the interaction, two classes of cooperative learning were analyzed in English classes at H Middle School located in H. To figure out the interaction, the independent variables were classified into the individual academic achievement level and the gap of academic achievement in the group. The dependent variables were analyzed by word counting, turn taking and message types and frequency analysis, content analysis and nonparametric Mann-Whitney U test were conducted. The results of the study are as follows. First, there was a significant difference according to the level of academic achievement. The students with high academic achievement showed more speech than the students with low academic achievement. Second, the group having higher academic achievement difference showed more turn takings than the group having lower academic achievement difference. Third, in all learners and groups, the frequency of sharing information messages was the very highest, followed by disagreement finding, making knowledge, evaluating knowledge but hardly appeared. Finally, the group with larger difference in academic achievement had higher frequency of message of explaining and confirming the task than the group with smaller difference and there was a significant difference. These results show that to promote active interaction in cooperative learning, it should be designed considering how to make groups by academic achievement and degrees of structured task.
