Learning devices are tools or components used in the learning process needed to support the learning process. the purpose of this study is to develop learning tools based on the accelerated learning approach. The implementation of this research was carried out on the third grade students of SDN 003Tasik Juang. This research is a research development. Product trials are carried out in two stages, namely with trial 1 (limited test) and trial 2 (limited deployment). The results of the study showed that, learning tools developed using the Accelerated Learning approach were declared valid and feasible to be used by obtaining a percentage of 83.5% the category was very valid. Learning tools developed using the Accelerated Learning approach are declared practical based on the results of the observation sheet of the implementation of the learning process with an average value of 87.5 very good categories as well as from student questionnaire response data with an average value of 88.5 with very good categories. The learning tools developed are effective based on the acquisition of learning outcomes that are above the minimum completeness criteria with classical completeness of 84.9%. Based on these results it can be concluded that the development of learning tools based on a valid, practical, and effective Accelerated Learning approach was developed in students of class III SDN 003 Tasik Juang.

The main problem in this research is to find out the design of valid teaching materials and the practicality of teaching materials. This research is a Research & Development (R&D) research method. To develop the product, this research uses a 4-D development model consisting of four stages, namely: (1) the defined phase, (2) the design phase, (3) the development phase, and (4) the disseminate stage. This research was conducted in class V of SD Negeri 1 Lalebbata Palopo, which acted as the subject of the study was the fifth-grade students totaling 25 people. Data collection techniques in this study are: observation, documentation, Questionnaire, and Validation. Analysis of the data used by the researcher was to test its validity by using the Aiken's formula and for analyzing student questionnaire response data and observations using descriptive statistical analysis. The results of this study indicate that the integrated religious neuroscience-based teaching material is said to be valid by three validators with several revisions so that it can be said to be valid and can be tested, then this teaching material can be said to be interesting because the results from the questionnaire responses of 20 students tend to agree with teaching material developed. Thus this research needs to be socialized so that it can become a consideration of teachers in schools in improving students' writing skills.

Learning tools are one important aspect to determine the success of a learning design. Student worksheet is one of the learning tools. The purpose of this study is as follows. 1) to find out how to develop a mathematics learning worksheet in the form of comics based on guided discovery on linear program material, 2) to find out the validity and practicality of a mathematics learning worksheet in the form of comics based on guided discovery on linear program material. In this research the method used is the development method. So the research explained that what was developed was a comic-based worksheet based on guided findings on linear program metrics. The subjects in this study were students of class XI Vocational School Wisnuwardhana Malang. Based on the LKS development research results that have been obtained that the validity results assessed by three validator experts are 1) material expert validator, 2) media expert validator, and 3) linguist validator reaches a percentage of 72.20%. In this criterion, the worksheets that were developed were good (valid) and the results of practicality were obtained from the student questionnaire responses and obtained an average value of 3.3 which in this criterion was declared good (practical). From the development of LKS in the form of comics based on guided discoveries on linear program material, it was concluded that the development of LKS is valid and practical so that it is suitable to be used in mathematics learning.
