Vocational teachers need to equip their students with meaningful and relevant required workplace competencies. As a result, vocational teachers should always stay updated on their knowledge and skills regarding the development of science and technology in the world of work. More specifically, in the automotive vocational expertise domain, problem-solving abilities become the crucial skills students need to master. Hence, equipping prospective automotive vocational teachers with sustainable learning and problem-solving abilities is indispensable. In this case, the metacognition theory could facilitate students with learning-how-to-learn activities, which is an essential skill for sustainable learning and learning to teach and equip them with problem-solving abilities. Therefore, bringing the metacognition theory, supported by other relevant theories, into teaching and learning activities would be beneficial in dealing with those issues. This study aimed to design and develop a metacognition-based digital problem-solving worksheet. This digital worksheet was expected to facilitate students with learning-how-to-learn activities and equip them with problem-solving abilities effectively. There were four main research objectives and questions in this study, which were related to; 1) the practical problem that needs to be addressed, 2) the didactic design, 3) the usability, and 4) the effectiveness of the digital worksheet. Design-based research was used to answer the research questions. This is a multi-methods research design, which means many methods exist to achieve the research aim and objectives. This research design comprised six stages; analysis and exploration (stage 1), design and construction (stage 2), evaluation and reflection (stage 3), analysis and exploration (stage 4), design and construction (stage 5), and evaluation and reflection (stage 6). Stage 1 was used to explore the practical problem as the answer to the first research question. Stages 2 up to 5 were used to formulate the digital worksheet's didactic design as the answer to the second research question. Stage 6 was used to evaluate the usability and effectiveness of the digital worksheet as the answer to the third and fourth research questions, respectively. Firstly, in answering the first research question, three semi-structured interviews were used as the data collection techniques in the first research stage. The findings of this stage stated that sustainable learning, learning to teach, and problem-solving abilities became the needed competencies prospective automotive vocational teachers need to master. Additionally, the findings stated that automotive fault diagnosis learning was the highest-order thinking subject that had a practical problem on it. The quality of the instructional toolkit for this subject required to be improved since the existing toolkit was a conventional observation sheet and still allowed students to conduct trial-and-error stages. This was the practical problem that this research would address. Secondly, in answering the second research question, a focus group discussion, expert-based evaluations, user-based evaluations (formative usability evaluation), and final revisions were used in the second, third, fourth, and fifth research stages, respectively. The focus group discussion aimed to discuss the materials needed to develop the digital worksheet. Following that, expert-based evaluations and user-based evaluations were conducted to evaluate the initial digital worksheet based on the experts' and users' perspectives, respectively. Several revisions were done based on those evaluation results, and the digital worksheet's final didactic design was finally realized. The findings of the didactic design stated that the worksheet was in a digital form and used blended learning with flipped classroom strategy, so students need to have three different learning times; 1) before, 2) during, and 3) after classroom activities. Furthermore, constructivism learning theory, adult learning theory, metacognition theory, experiential learning theory, and reflection theory became the fundamental theoretical knowledge basis for developing this digital worksheet. Moreover, problem-based learning, automotive fault diagnosis procedures, and worksheet stages became the digital worksheet development's fundamental practical knowledge basis. There were seven stages that students need to do during the problem-solving learning; 1) introduction, 2) observing, 3) collecting information, 4) analyzing, 5) testing, 6) rectifying, and 7) checking all systems. There were many steps in every stage above, and many instructions and self-reflection questions in every single step. Additionally, in every step, the teachers had an opportunity to give feedback on the student's work, and the students could have discussions with other students at the end of every stage. The self-reflection questions on every instruction, the teacher's feedback on every step, and the discussion results at every stage were used to regulate the students' self-cognition. Thirdly, in answering the third and fourth research questions, a questionnaire survey and an experimental study were used as the final research stage, respectively. First, the survey of summative usability evaluation consisted of four elements: usefulness, ease of use, ease of learning, and satisfaction. The findings of this evaluation stated that the usability level and those elements' usability levels were all in very high categories. Additionally, it could be determined that the usefulness, ease of use, and ease of learning significantly influenced the students' satisfaction simultaneously and independently, except for the variable of ease of learning. Second, the effectiveness findings stated that the digital worksheet significantly effectively facilitated students' learning-how-to-learn activities and equipped them with problem-solving abilities.:ABSTRACT (EXECUTIVE SUMMARY) ABSTRAKT (ZUSAMMENFASSUNG) ACKNOWLEDGMENTS AND DEDICATION TABLE OF CONTENT LIST OF FIGURES LIST OF TABLES LIST OF ABBREVIATIONS CHAPTER 1.
