This research is motivated by the low mathematical reasoning ability of students and the low quality of the learning tools used by the teacher. Based on the preliminary analysis, researcher obtained information that the mathematics learning tools used by the teacher were not in accordance with the rule of the Kurikulum 2013. Thus, it is necessary to design a mathematics learning tools that is in accordance with the demands of the curriculum and is oriented to students’ mathematical reasoning abilities that are valid and practical to use.
The learning tools developed in this research were the Syllabi, Lesson Plans (RPP), and Student Worksheet (LKPD) of Polyhedron material in mathematics learning. The learning tools are developed with using the Discovery Learning model and learning experiences in a scientific approach. A scientific activities contained in the Discovery Learning model reflects the existence of a logical and systematic thinking process so that it is believed to be able to develop students' mathematical reasoning abilities.
Research and Development is the type of his research. The development model used is the ADDIE development model by Dick and Carry that consist of several stages, namely: Analysis, Design, Development, Implementation, and Evaluation. The data used in this research are qualitative and quantitative data. Qualitative data were obtained from interview with mathematics teachers regarding the learning tools used, validator's suggestions or comments on the developed-learning tools, as well as student responses to the content and appearance of the developed-LKPD. Quantitative data were obtained from the validator's assessment of the validity of the developed-learning tools and the student response questionnaire scores on the practicality of the developed-LKPD.
The research instruments used were validation and practicality sheets. The validation sheet was used to view the level of validity of the developed-learning tools (Syllabi, Lesson Plan (RPP), and Student Worksheet (LKPD)), whereas the practicality sheet was used to view the level of practicality of the developed-LKPD. The developed-learning tools are declared to be valid if the percentage of validation is more than 70% and is declared to be practical if the percentage of practicality is also more than 70%.
The first stage of development process is an analysis of three components, namely: learning tools, materials, and student characteristics. The results of the analysis illustrate that the students' mathematical reasoning ability is low, along with the low quality of the learning tools designed by the teacher. In the second stage, researcher designed learning tools based on the Discovery Learning model as an alternative to train students' mathematical reasoning ability, by first choosing the appropriate format. In the third stage, researcher developed the learning tools according to designs that have been prepared previously and then the learning tools were validated by the validator. In the next stage, the
researcher tested the developed-learning tools in the learning process to see the level of practicality. In the final stage, researcher should conduct an evaluation to see the impact of the learning process using the developed-learning tools on students' mathematical reasoning abilities. Yet, this stage was not carried out because of the Covid-19 situation.
Based on the result of validity data analysis, it was found that the average validator assessment results for the developed-syllabi was 4,61 (92,2%) with a very valid category, the average validator assessment for the developed-RPP was 4,67 (93,4%) with the category very valid, and the average validator assessment for the developed-LKPD is 4,64 (92,8%) with a very valid category. Thus, the developed-learning tools are suitable to be used as learning tools oriented to students' mathematical reasoning abilities.
Based on the result of practical data analysis, the average score obtained from the students response questionnaire for the validated-LKPD were declared very practical category with a percentage of 92,54%. This finding shows that the developed-LKPD is very practical to use as a learning tool oriented to students' mathematical reasoning abilities.
