“…As ICT expertise becomes essential in work, thus potential to change the way a person learns and obtains information. It also provides the teachers the opportunities to develop instructional techniques in order to get maximum results (Fakhrunnisaa & Munadi, 2019;Roza, et al, 2017). The teacher's position in learning tends to be a facilitator who embraces and provides the latest information related to the development of science to students from various sources to help students understand concepts in digital form.…”

The implementation of learning media based on ICT (Information and Communication Technology) on chemistry was found to be very low. For this reason, ICT-based chemistry learning media which utilized autoplay application were developed in this research. The validated product of the learning media based by autoplay on chemistry can be implemented as a learning medium to improve students' communicative character. This research was designed by using the Plomp model in the form of Research and Development (R&D). Data of this research were collected by validation sheets, questionnaire responses (teachers and students), and communicative observation sheets with descriptive statistical analyses and independent sample t test. The validity results showed that the average percentage from media expert and material expert judgment were 88.25% and 91.69% with a category of valid. Moreover, the results of the response of teachers and students respectively obtained an average percentage score of 85% and 81% with a category of very interesting. Then, the results of the independent sample t test for 0,000 <0.05 indicated that there were significant differences in the communicative character of students before and after the use of learning media based on autoplay on chemistry with a percentage of 72.25%.

“…The LKPD structure gives students a narrow view of mathematics subject matter because the material, sample questions, and question exercises that are presented lack explanation. One branch of mathematics namely geometry which is considered difficult by most students, it clearly makes a negative impact on their ability to understand geometry (Roza, et al, 2017).…”

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.

The results of the preliminary study indicate that the learning tools used by the teacher do not meet the 2013 curriculum rules. This study aims to produce learning tools with the application of discovery learning to improve Mathematical Problem Solving Ability (KPMM) on social arithmetic materials for grade VII junior high school. This study used the Borg and Gall development model with stages: (1) research and data collection; (2) planning; (3) development of learning tools; (4) limited trials; (5) product revisions; (6) field trials; (7) product revisions; (8) final product test; (9) revision of the final product; and (10) dissemination and implementation. The validation results showed that it was very valid with consecutive average percentages for KPMM problems that were 94.64%, syllabus was 90.10%, RPP was 93.14%, and LKPD was 92.60%. In the final product test phase, learning tools were used through pre-experimental research to see the increase in KPMM. The final product test results indicated that there was an increase in KPMM of students using learning tools. This means that the learning tool with the application of discovery learning in social arithmetic material in class VII SMP has been valid, practical, and effective.
