The results of student mathematics learning in Indonesia are still relatively low, both at national and international levels. This is because in the learning process the teacher still uses theapproach teacher-centered. So that students are not optimal in developing their knowledge. Therefore, one learning model that can observe this needs to be pursued in a form of learning that is able to increase student activity and learning outcomes is one of thelearning models Guided Discovery Learning. The objectives of this study are (1) To compare the learning outcomes of students taught withmodels Guided Discovery Learning with student learning outcomes taught with conventional learning, (2) To find out the improvement in student learning outcomes taught withlearning models Guided Discovery Learning and ( 3) To find out the response of students after taking part in learning with thelearning model Guided Discovery Learning for students at Bandar Baru Middle School. The research method used was a type of Quasi Experiment with the type of control group pre-test post-test design. The population in this study were all eighth grade students of Bandar Baru Junior High School andsamples were taken, Random namely class VIII3 as the experimental class and VIII6 as the control class. Data collection uses learning outcomes tests, and student response questionnaires. Analysis of student learning outcomes data used t-test and N-gain while analysis of student response data was carried out through analysis of average score criteria. From the results of data processing it can be concluded that the learning outcomes learned usinglearning models Guided Discovery Learning are better than student learning outcomes taught with conventional learning,learning models Guided Discovery Learning can improve student learning outcomes and student responses to learning models Guided Discovery Learning very positive.

This study aimed to develop learning tools to help children with learning disabilities of comorbid dyscalculia-dyslexia. The learning tools were developed using the 4D model. Each stage of development was conducted based on the materials focused on in this research, namely the topics of recognizing and understanding numbers, sorting numbers, and operating numbers. This study involved 280 students, ages between 7 and 8 years old, from four elementary schools. Students took a series of tests, and 11 students were found with comorbid dyscalculia-dyslexia. The results of this study provided an overview related to the learning tools developed, tested, and implemented in mathematics learning for students with dyscalculia and dyslexia. This finding was indicated by the analysis results of recognizing numbers, sorting numbers, and operating numbers using paired-sample t-tests (p< 0.05). The results showed increased students' essential mathematics ability based on the pretest and posttest scores.

So far, the teacher's thought process in solving a math problem has rarely been paid attention to by the teacher. The thinking process of students in solving math problems includes intuitive and analytical thinking processes. The aim of this research is to explore the intuitive and analytical thinking process of junior high school students in solving UN questions. The research method used is qualitative research that is exploratory in nature by selecting subjects who have high abilities in mathematics. Data collection in the form of descriptions of students' intuitive and analytical thinking processes was carried out through interviews. The results obtained in this study are a description of the process that students go through in mental when students solve math problems in the form of questions National Examination. The results of the study can be concluded that students in solving mathematics problems in the National Examination prioritize the process of intuitive thinking, where students can spontaneously and directly pour out ideas for solving the problems given. In addition, in the further process, students also use analytical methods. Analytical thinking processes are carried out by students by detailing the answers based on the information in the questions.
