This research explores the integration of artificial intelligence (AI) into blended learning modules for multimedia and animation students at Bangkok Thonburi University. The study aims to: Investigate the implementation of AI-assisted teaching approaches. Assess student satisfaction with AI integration in learning. And examine the advantages and limitations of AI-supported learning. The research involved 20 students from the Multimedia and Animation program. Data was analyzed using mean and standard deviation. The research instruments included: AI-integrated modules evaluated by AI experts. Student satisfaction questionnaires. And figJam web platform. The findings indicate a positive student perception of AI integration, with Microsoft Bing, Google Bard, and ChatGPT being the most preferred AI tools. Students particularly favored Microsoft Bing and were least enthusiastic about ChatGPT. The advantages of AI included the ability to search for Thai language-supported information, access reliable sources, and generate creative content. However, limitations were also identified, such as the need for precise Thai language commands, usage restrictions, and the potential for inaccurate image generation. Students demonstrated overall satisfaction with AI integration in blended learning modules. Microsoft Bing emerged as the most preferred AI tool among students. AI-supported learning was perceived as beneficial for information retrieval, resource access, and creative content generation. The need for accurate Thai language commands and potential for inaccurate image generation were identified as limitations of AI integration.</p> 2024-06-02T00:00:00+07:00 Copyright (c) 2024 https://so01.tci-thaijo.org/index.php/bkkthon/article/view/270190 Problems of Applying Artificial Intelligence (AI) to Assist in the Teaching and Learning of Design Course 2023-10-18T11:20:38+07:00 Borvonsak Markpoon borvonsak.mar@bkkthon.ac.th Pongtep Phonprasert borvonsak.marll@bkkthon.ac.th Panya Niyomtong borvonsak.marlll@bkkthon.ac.th Thanyathorn Tangchitpornchai borvonsak.marllll@bkkthon.ac.th <p>Currently, Artificial Intelligence (AI) is playing an increasingly important role. Therefore, researchers are interested in applying AI as a teaching tool in design courses to identify problems that can be effectively addressed using AI. The objectives of this study are as follows: 1. To investigate the problems of applying AI in teaching and learning. 2. To examine the satisfaction of students with the use of AI as a teaching tool. And 3. to compare the learning outcomes of students who use AI with those who do not, considering their different learning experiences.</p> <p>Summary of Research Findings key Challenges of AI Integration in Design Education: English Prompt Formulation: Students struggle to effectively formulate prompts in English due to limited language proficiency. Design Function Utilization: Difficulty in navigating and utilizing the design functions offered by AI tools. Token Usage Limitations: Restricted daily token usage hinders exploration and experimentation with AI tools. Positive Outcomes of AI Integration: Enhanced Design Efficiency: AI simplifies and streamlines the design process, leading to more efficient design output. Reduced Design Time: AI reduces the overall time required to complete design tasks. Implications: address English Language Support: Provide comprehensive English language support to aid prompt formulation.
