This research was motivated by the still limited learning of mathematics as a means of supporting learning in the 2013 Curriculum. The purpose of this study was to produce some products in the form of learning devices (syllabus, RPP and LKPD) on the material for the flat side building of VIII Middle School with discovery learning models that meet valid, practical, and effective criteria for improving students mathematical critical thinking skills. Learning tools are developed using the 4-D model, which are define, design, develop and assess. The research instrument used was an instrument of validity in the form of a validation sheet to assess the feasibility of the syllabus, RPP and LKPD as well as a practical instrument in the form of a teacher observation sheet activity in applying the discovery learning model and student questionnaire responses to assess the practicality of LKPD. The results of the validation of the experts stated that the product developed reached a valid category with an average rating of 76.67% for syllabus, 76.67% for RPP and 88.04% for LKPD. Learning devices are considered very practical in small group trials with an average response of 96.44% students and large group trials from the observation sheet of teacher activity 93.71% and the average response of students 87.77%. The learning tools have been proved to improve students mathematical critical thinking skills in terms of an average N-gain of 0.53 in the medium category.

This study aims to describe the impact of online mentoring activities in implementing the RADEC (Read, Answer, Discuss, Explain, and Create) learning model on the competence of elementary school teachers in training students’ critical thinking skills. The method was a pre-experiment with a one-group pretest-posttest design involving 25 elementary school teachers in Indonesia. The teachers received online mentoring in implementing RADEC learning model. The research instrument was a questionnaire to measure teachers’ knowledge and skills in training critical thinking. The data processing technique was carried out by calculating the mean and the percentage of each item to obtain a description of the teachers’ knowledge and skills in training students’ critical thinking before and after treatment. The data were analyzed inferentially with a paired sample t-test using SPSS version 22 software to see the impact of the treatment on teachers’ competence in training critical thinking. Based on the results of the paired-sample t-test, for both the knowledge and skills aspects, the probability value (sig) was 0.00 <0.05. This result means that there was a significant difference in the knowledge and skills of teachers in training students’ critical thinking skills before and after mentoring activities. The study results indicate that the online mentoring in implementing the RADEC learning model improved teachers’ competence in training elementary school students’ critical thinking skills.

This study aims to improve critical thinking skills and mathematics learning outcomes of fourth-grade students of SD Tingkir Tengah 02 Salatiga in the second semester of the 2018/2019 academic year. Critical thinking and learning outcomes are low because the teacher uses the lecture method. The author chooses the Open-Ended model assisted by powerpoint media as a solution. Research procedures include planning, action, observation, and reflection. The results showed an increase from the initial condition with 9 students or 25.71% completed and 29 students or 74.29% not complete. The implementation of the first cycle results obtained 29 students or 82.86% completed and 6 students or 17.14% did not complete. Cycle II as a follow-up and improvement of the first cycle with the acquisition of achieving attainment of 35 students or 100%. The results obtained by the conclusion of the application of Open-Ended learning assisted by powerpoint media can improve critical thinking skills and mathematics learning outcomes of fourth-grade students of SD Tingkir Tengah 02 Salatiga second semester of the 2018/2019 academic year.
