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.

Discovery learning is a learning situation on wich the principle content of what is tobe learned is not give but must be independly discovered by student. The effectiveness of guided discovery learning model to improve students’ critical thinking skills uses 6 indicators, are: formulating problems, formulating hypotheses, analyzing date, providing alternatives, summing up, communicating and applying principle. The guided discovery learning model was included in the effective category in terms of: (a) Improvement (N-gain) of students’ critical thinking skills by 0.65 with moderate criteria and (b) Students respond positively to learning using guided discovery learning model and its learning tools on implementation.

This development research aims to produce a product in the form of a discovery learning model to improve students' critical thinking skills in physics. The research design used is the 4D model which consists of define, design, develop and disseminate. Products developed in the form of a syllabus, lesson plans (RPP), material analysis, student worksheets (LKPD), and test instruments in the form of description questions. Data collection techniques using validation sheets and questions. The validity data were analyzed by determining the final mean value (NA) of the expert validators and practitioners. The improvement of critical thinking skills is analyzed using standard gain from the results before and after the learning process. Data validity results show that the learning device developed is at a very valid level with a final average value of 3.48 so that the developed device is suitable for use in learning. The data on the reliability results of the learning tools developed with an average value of 93.21% were included in the reliable category. The ability to think critically with discovery learning models has increased with a gain value of 0.38. Based on the results of these data, it can be concluded that the discovery learning model that was developed is effective to improve students' critical thinking skills in physics.Keywords: Learning tools, discovery learning model, critical thinking skills in physics

Lack of critical thinking skills in students is a problem faced in thematic learning at <em>SD Negeri 2 Kedungrejo. </em>Therefore, it had an impact on low learning outcomes. From this problem, this study aims to improve critical thinking skills and learning outcomes through discovery learning model. Classroom Action Research (PTK) was used in this study. While the data collection instruments included observation sheets, test questions, and questionnaires. The data analysis technique used a comparative descriptive technique. The subjects of this study were 22 4<sup>th</sup> grade students of <em>SD Negeri 2 Kedungrejo.</em> The results of this study indicated an improvement of critical thinking skills and students’ learning outcomes. This can be proven by the average value of students' critical thinking skills in cycle I of 54.67% and increased again in cycle II by 69.84%. Whereas for students’ learning outcomes, in cycle I showed students’ average score of 70. Moreover, it increased by an average value of 80 in cycle II. To sum up, these results showed that applying discovery learning model in the online learning process were able to improve students’ critical thinking skills and learning outcomes.

Historical learning has not reached optimal in the learning process. It is caused by the history teachers’ learning model has not used the innovative learning models. Furthermore, it supported by the perception of students to the history subject because it does not become final exam (UN) subject so it makes less improvement and builds less critical thinking in students’ daily learning. This is due to the lack of awareness of historical events and the availability of history books for students and teachers in the library are still lacking. Discovery learning with scientific approach encourages students to solve problems actively and able to improve students' critical thinking skills with scientific approach so student can build scientific thinking include observing, asking, reasoning, trying, and networking.

<em>One of the problems in our education world is the weakness of the learning process, which has an impact on metacognitive skills and critical thinking skills of students. One of the contributing factors is that the teacher only provides existing material without any development related to the real world of students. Thus the effort that can be made is that before carrying out the learning process the teacher as an educator must have a learning plan, which is included in the learning tool. Because in a learning device a teacher can design learning methods and materials that are considered innovative when used. One of the innovative learning methods that can build active learning conditions for students is to use a local wisdom-based learning model. The research objective was to determine the validity of learning tools through a learning model based on local wisdom of South Kalimantan to improve metacognitive skills and critical thinking of students in the classification concept of living things. This study develops products in the form of RPP, LKPD and Questions. The development method used refers to 4-D development which has 4 stages, namely define, design, develop and disseminate. The type of data used is qualitative and quantitative data. The instrument used was a validation sheet that was declared valid based on the results of the expert team's assessment. Data analysis techniques were carried out by matching the results of empirical validation from experts with predetermined validity criteria. The results of this study indicate that local wisdom-based learning tools are worth trying out, because the scores obtained from the validation results show validity with a percentage of&gt; 67.19% which is considered valid enough and has no revised information</em>

The current study describes how the guided-discovery-learning model impacts students' conceptual understanding (SCU) and students’ critical thinking skills (SCTS) on the topic of solubility. The quasi-experimental research with a posttest-only nonequivalent control group design was used in this study. The experimental group (45 students) and the control group (47 students) were selected by the saturated sampling technique. Data on SCU was collected using an objective true false test instrument with correction/proofing, while data on critical thinking skills was collected using an essay test instrument. The research data were analyzed descriptively and statistically (Mann-Whitney U). The research found the SCU (mean= 81.51 vs. mean= 72.81) and SCTS (mean= 70.46 vs. mean= 58.43) in the experimental group was better than the control group, both descriptively and statistically (p < 0.05). These findings indicate that the guided-discovery-learning model significantly impacted SCU and SCTS on the solubility topic.
