Abstract

Often students are only given practical problems in the form of algorithms without inviting them to think at a high level and almost never given daily problems in the form of projects. From this it can be seen that there are still teachers who have not carried out directives from the government that is to assess competencies made in the assessments that require students to demonstrate certain competencies using projects. This study aims to produce worksheets in the form of school cooperation projects on the value of direct proportion and social arithmetic, and analyze students' answers in solving these problems and the implementation of learning is carried out using a lesson study for learning community (LSLC) system. This research uses a design research method which is a form of qualitative approach. The stages in the design research type of development studies. The subjects of this study were seventh grade students of SMP Palembang. From this study, student worksheets were generated about direct proportion and social arithmetic consisting of four activities including determining the price list of goods purchased, determining the price of capital goods, reporting prices of goods and selling prices, and determining conditions of sale. Based on the results of the analysis of students' answers to worksheets, some students can perform procedures of direct proportion and determine conditions of sale (profit, loss, or break even) so that this worksheet has been deemed valid and practical to use.

Abstract

Numeracy and literacy are the focus of Indonesia's education system. This is evident from the implementation of the Minimum Competency Assessment (AKM), which has been part of the national annual assessment since 2021. The results are analyzed and reflected upon to assess the quality of education in implementing schools. Students' numeracy skills can improve if they use reasoning to solve problems. Reasoning connects the concepts they hold with the context of the problem at hand. Reasoning results are used to interpret, analyze, and make decisions. The reasoning in question focuses on adaptive reasoning (reflection, explanation, and justification). Research was conducted to describe the adaptive reasoning of high school students through the answers of students who participated in a reasoning competition. The instrument used is a numeracy test. This research is qualitative with descriptive methods. Analysis was conducted on the three student answers that obtained the highest scores (purposive sampling) and focused on the fertilizer theme. This theme is presented in graphic form as a stimulus with two questions that students need to answer. The data analysis technique in this research involved reducing the data. The result obtained was that one student used aspects of adaptive reasoning (reflection, explanation, and justification) completely in answering questions. This indicates that this student can solve problems using adaptive reasoning. This student is said to have good numeracy skills because they can use adaptive reasoning.BAHASA INDONESIA ABSTRACT: Literasi dan numerasi menjadi salah satu fokus pada dunia pendidikan di Indonesia.

Abstract

The fact that gadgets are no longer luxury items and every student certainly has them presents an opportunity for teachers to create meaningful learning. One way to do this is by conducting learning assisted by PhET Simulations. These simulations offer various concepts in mathematics, physics, biology, and chemistry to be taught in the form of simulations. The use of these simulations allows the role of the teacher as a learning facilitator to be effectively carried out theoretically. However, the use of simulations has not been carried out to assist teachers in teaching material. Strengthening needs to be done. The strengthening is carried out at SMP N 1 Pemali through providing focused reinforcement for Mathematics and Natural Sciences (IPA) teachers. The reinforcement implementation is equivalent to a 6-hour training with activities starting and ending with tests to see if there is any improvement in understanding related to the reinforcement provided. Information was obtained indicating a good improvement in understanding related to the use of PhET as a learning medium for teachers is 37,5 %. In addition, the reinforcement provided received a positive response. Reinforcement practice in using PhET simulations has a good impact on MIPA SMP’s teachers as facilitators in learning.
