<p style="text-align: justify;">Literacy ability is an individual's ability to reason, formulate, solve, and interpret mathematically to solve problems related to daily life. Executive function is a cognitive aspect that has a relation with mathematical literacy. One of some aspects that affects the low mathematical literacy ability is the aspect of executive function. This study aims to investigate the characteristics of mathematical literacy based on the executive function aspects of 15 years old students. A qualitative method with a descriptive approach is employed in this study. The present research applies interview guidelines, questionnaires, and students' mathematical literacy tests as the instruments. Research subjects are junior high school students in grade VIII from two different schools. The result shows that the students' executive function influences mathematical literacy ability. Students' mathematical literacy ability is not fully achieved by fulfilling all the indicators involved. Another aspect found in the research is the low critical thinking ability impacts the achievement of mathematical literacy ability indicators.</p>

The study aims to produce the e-learning physics of Newton's legal material to develop the critical thinking skills of high school students who have higher and practical validity rates. The model of development research used is Rowntree models. The evaluation phase used is Tessmer's formative evaluation consisting of four phases: Self evaluation, expert review, one-to-one evaluation, and small group evaluation. Data collection techniques using walkthroughs and polls. This level of e-learning validity is judged by three experts, namely in material aspects, learning design aspects, and e-learning aspects as well as data analysis using the Aiken V Index to determine the consensus of the experts. The results of the development of e-learning indicate that the resulting media is suitable for use in learning physics. This can be seen from the Aiken V index value of 0.94 with a high level of validity category. Meanwhile, one-to-one evaluation and small group evaluation are obtained by average result of 81.84% and 90.00% and also includes very practical category.
