Abstract

The goal of this study is to detail the purchasing and selling procedures employed by traders at the Tomohon faith market as well as the arithmetic computation techniques they employ. Research of this kind is qualitative. Interviewing and participant observation techniques were utilized to acquire the data. In this study, the data analysis is qualitative descriptive. Ten traders from the Tomohon faith market were chosen at random to participate as research subjects in this study. The study's findings demonstrate that Tomohon faith market vendors round up their prices when selling their items. The way that traders provide change is to round up the cash that needs to be paid in advance to the nearest tenth, then add it up until the whole sum matches the cash the buyer has paid. The methods used by research participants to calculate addition, subtraction, and multiplication differ significantly from those used in classroom instruction. The value 0, which functions as thousands, is always disregarded. Start by adding the thousands with the thousands, then the hundreds with the hundreds, to determine the total. Some people also finish first to the nearest tens value. If the number being decreased, for example, is 50,000 - 13,000, the reduction procedure is 13 to go to 20 less 7. Then 50 – 20 = 30. The result is 37, which equals 37,000. In addition, you must deduct the first tens of thousands from the second tens of thousands before removing the remaining part of the second figure. Multiply the number from the front number first, for instance, tens of thousands, then thousands, and so on, to calculate the multiplication technique. Find the number that can be divided by the divisor to calculate the division. The outcome of the previous division is then applied to the divided number. This process is continued until all the divided number has been used. The outcomes of these divisions should then be added.

Abstract

Joan Shelomikha Mawikire. 19504045. Development of High Order Thinking Skill (HOTS) Based Learning Tools. Mathematics Department. Faculty of Mathematics, Natural and Earth Sciences. Manado State University. Tondano 2023. The aim of this research is to develop learning tools based on Higher Order Thinking Skill (HOTS) on tube material in class VII A of SMP Negeri 1 Tondano. To see the quality of the development of this learning tool, it is seen from three aspects, namely validity, practicality and effectiveness. This type of research is Research and Development (R&D) using the ADDIE (Analysis, Design, Development, Implementation and Evaluation) model. According to the validity aspect, the expert validator's score for the teaching module was 94 with very valid criteria and for the Student Worksheet (LKPD) the score was 92 with very valid criteria. According to the practical aspect, assessment is seen from the teacher's response and the student's response. The assessment score obtained from the teacher's response was 96 with very good criteria and the assessment score for student responses was 88 with very good criteria. According to the effectiveness aspect, the learning tools developed are effective as seen from the completion of the student learning outcomes test, which is 81%. So the results of this research are the learning tools developed that are valid, practical and effective for use in learning.
