The purpose of this study was to describe the extent of misunderstandings experienced by high school students while tackling Minimum Numerical Ability (AKM) questions modeled on the basis of domain-dependent cognitive styles. The number of students used as subjects in the study was her XI-IPS students in class three (3). The study was conducted at Tawangsari, Tulungagung District, Kedungwal, MA Darul Hikma, Tulungagung District, Jl KH Abu Mansur I. The study was conducted in even-numbered terms of the academic year 2021-2022. A targeted sampling method with the GEFT test (Group Embedded Figure Test) is used to determine research topics and classify students as having subject-dependent cognitive styles or not (subject-dependent). The results showed that students were categorized based on their AKM numbering test response results of low, medium, and high misconceptions. The number of questions is 3 questions. The first item is used to make sure that the indicator cannot repeat the concept. The second item is used to determine that the indicator fails to formulate the concept correctly in various mathematical representations. The index cannot determine the formula that answers the question. Indicators cannot apply formulas or algorithms to solve problems. The third item is used to see indicators of inability to use formulas or problem-solving algorithms. The results obtained show that subject-specific style students with low misunderstandings score higher from responses to AKM numbering questions than students with moderate and high misunderstandings

“Who Am I”: The Role of Character Strength in Self-Awareness Emerging Adulthood

Previous research shows that self-awareness is important for emerging adulthood. Individual knowledge of himself is required, specifically the strength of his character, to increase self-awareness. For this reason, this research shows the role of emerging adulthood character strengths on self-awareness. The research was carried out using a non-experimental quantitative approach with a research design in the form of a survey. Sampling was done using simple random sampling. The measuring instruments used are the Indonesian version of character strength developed by the VIA Institute via the viacharacter.org page formulated by Peterson & Seligman (2004) and the Self-Awareness Outcomes Questionnaire (SAOQ) created by Sutton (2016), which researchers adapted. These two measuring instruments have been proven to be valid and reliable in measuring the selected variables. Data collection was carried out using Google Forms, and a total of 142 participants were used for hypothesis testing. Hypothesis testing using a simple linear regression test shows that character strength plays a significant role in predicting emerging adulthood self-awareness with a predictive power of 64 per cent, and the direction of the relationship between the two is in the same direction. This means that the higher the strength of character, the greater the self-awareness. Thus, it is known that the true potential of emerging adulthood can be maximized if individuals are aware of their character strengths. This is because character strength can be an element in self-exploration and self-understanding. Research suggestions are attached
