Advancements in technology, particularly the internet, have provided learners with extensive opportunities to access various resources for independent learning. However, not all learners can effectively utilize digital media and technology, and many face challenges in selecting appropriate materials and methods to support their learning. This study examines the self-directed learning strategies of a Japanese language learner, addressing the following questions: (1) What strategies are employed for independent learning? (2) What media are used, and how does he facilitate self-directed learning? This study employs a qualitative research approach, specifically narrative inquiry, to explore the learner’s experiences. Data were collected through semi-structured interviews and analyzed to identify patterns in self-directed learning strategies. Findings reveal that the learner adopt multiple strategies, including goal setting for both short-and long-term learning, adaptation, combination, evaluation, and validation. Additionally, the learner engages with various online resources, such as interactive learning platforms, receptive learning materials, social media, and authentic content. The study further identifies six key aspects of technology used in self-directed learning, with variations in frequency based on individual needs and perceived advantages and limitations.

Mathematics plays a crucial role in developing students' problem-solving abilities and independence. Educators need to consider the varying characteristics of students when it comes to solving problems, one of which is their adversity quotient (AQ) level. The adversity quotient relates to a student's ability to handle complex problems or to overcome challenging situations. This research aims to analyze the mathematical problem-solving abilities of Class X students in the context of Systems of Linear Equations in Two Variables (SPLDV) based on their Adversity Quotient (AQ). This qualitative, descriptive study involved selecting research subjects using an AQ questionnaire and was conducted in Class X. Data collection methods included testing, interviews, and documentation. Data analysis techniques included data reduction, data presentation, and conclusion drawing. The results indicate that subjects with the Climber type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, and use available information to re-check their answers. Subjects with the Camper type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, but often cannot use available information to re-check their answers. Subjects with the Quitter type can understand the problem and formulate a plan but struggle to solve the problem accurately and appropriately, and tend not to use available information to re-check their answers.
