ERRORS ANALYSIS OF HIGH SCHOOL STUDENTS IN SOLVING MATHEMATICS REASONING OF UTBK BASE ON KASTOLAN STAGES
This study aims to describe student errors and the factors that cause student errors in solving mathematical reasoning topic questions according to Castolan Stages. This research uses a qualitative approach with descriptive methods. The research subjects were 3 class XII high school students consisting of 2 female students and one male student. The research instruments used in the research were written tests and interviews. The results showed that students made three errors in solving the mathematical reasoning questions: conceptual, procedural, and technical. The causes of these three faults differ. As for student errors, (1) conceptual errors because students choose the wrong formula or formulas, so they don't answer questions; (2) procedural errors because students don't work on questions according to the steps requested, so they don't write down what was known and what was asked; and (3) technical errors. The cause of conceptual errors is pupils not understanding the subject and forgetting the formula. Procedure errors occur when kids don't know how to solve problems and aren't used to writing down what they know and what they're asked. Technical errors occur when pupils rush to solve problems and don't check their responses.

The sample chosen was a Purposive Sampling technique, and class VIII-F was selected as the control class and class VIII-H as the experimental class, the number of students was 35 people. Data was collected through a test in the form of 5 essay questions that measured mathematical and non-test connections as a SelfEfficacy questionnaire. Data analysis includes data normality test, data homogeneity test, t-test, and quantitative descriptive analysis. The research results stated; (1) The results of the Dependent sample t-test in the experimental class and control class each show the t_count < t_table value, so that (H0) is rejected and (H1) is accepted. (2) Independent sample t-test in the experimental class and control class also shows that the t_count < t_table value, so that H0 is rejected and H1 is accepted. (3) The results of the questionnaire validity test show that the value of t_count < t_table, so that H0 is rejected and H1 is accepted. This research concludes that there is a significant difference in the level of mathematical connection ability and Self-Efficacy between students who use Times Games and Tournaments with the help of Wordwall and conventional learning.
APPLICATION OF THE SELF TALK METHOD TO IMPROVE LEARNING ACTIVITIES OF STUDENTS OF PANJI 3 STATE JUNIOR HIGH SCHOOL
Learning activities are learning behaviors that are characterized by student activity during class learning. In the learning process, if a student does not do physical or mental activity to increase knowledge and skills, it will be difficult to achieve the goal from learning. Learning outcomes will be optimal if students carry out high learning activities, the more successful the learning process will be. Low learning activities are still found in class VII A and VII B students at SMP Negeri 3 Panji. The purpose of this study was to determine the effect of the self-talk technique to increase students' learning activities at school class VII at Panji 3 state junior high school. The design of this research is Pre Experimental Design. Researchers used a pretest and posttest design, because in this study to determine the role of the self-talk technique in improving the learning activities of the students used research sample, in this design, the sample is subjected to 2 measurements. The first measurement is carried out to measure the level of learning activity before being given treatment (treatment), and the second measurement is carried out level of learning activity after being given treatment (treatment).
ANALYSIS OF STUDENTS' MATHEMATICAL LITERACY BASED ON THE LEVEL OF PROBLEM SOLVING ABILITY OF HOTS PROBLEMS
This research aims to analyze students' mathematical literacy based on their level of problem solving ability on HOTS (Higher Order Thinking Skills) questions. Mathematical literacy is the ability that students must have to solve problems in learning mathematics in various contexts, one of which is HOTS type questions. The research method used is qualitative descriptive research. The sample for this research consisted of class VIII students at MTs Ichyaul Islam. Data was collected through mathematical literacy tests and HOTS questions relevant to the material on Systems of Linear Equations in Two Variables. The research results show that there is a relationship between students' mathematical literacy and their level of problem solving ability on HOTS questions. Students who have strong mathematical literacy tend to have higher problem solving abilities on HOTS questions. Students with high HOTS problem solving abilities are able to answer questions with high level thinking and are able to apply mathematical concepts in depth.
