Abstract

The problem experienced by service partners is the lack of knowledge of teachers related to CAR (Class Action Research) and its implementation so that teachers at Tamansari 1 and 2 Elementary Schools do not carry out CAR. In addition, the existing CAR trainings are not carried out continuously so that they do not bring results and motivate teachers to do CAR. The purpose of this community service is to strengthen CAR material to improve CAR-related knowledge, namely the basic concept of CAR, problem identification and problem solving in CAR, development of CAR Instruments, preparation of CAR proposals, CAR implementation and writing of CAR reports. In addition, the purpose of this PKM is to provide assistance in the preparation and implementation of CAR by guiding CAR 1 and 2 Yogyakarta elementary school teachers.The method used in the implementation of this service was the Workshop carried out with the lecture method (face to face), demonstration (practice), and the distribution of modules for strengthening CAR material and assistance was carried out with the method of coaching and implementing CAR together.community service results are that teachers in SDN Tamansari 1 and 2 can better understand the importance of CAR concepts, implementation of CAR, and CAR reporting.Keywords: Workshop, CAR, Collaborative.

Abstract

One of the goals of mathematics learning is that students are expected to have good understanding mathematics concept abilities. The application of discovery learning model in the process of learning mathematics is one of the learning modelsthat can improve students understanding of mathematics concepts. The learning process uses the discovey learning model so that students can find the concepts of the material being studied and can conclude their own concepts that have been found based on their ability to understand. This research aims to determine that: (1) students understand the mathematics concepts of discovery learning model in effective;(2) students understand the mathematics concepts of conventional learning model in effevtive; (3) the effectiveness of discovery learning model and conventional learning for understanding mathematics concepts, and to know in 11th Senior High School at SMA N 1 Gamping. This type of research is an experimental quasi experiment with research design Posttest Only Control Design. The population in this study were students of class XI IPS SMA N 1 Gamping. The sample in this study was class XI IPS 1 as an experimental class and class XI IPS 2 as a control class. The instrument used in the study was the observation sheet of the implementation of learning and the students understanding mathematics concepts test questions. Analysis of the data used is the t-test and the prerequisite test used are normality and homogeneity test. The result showed that using discovery learning model and conventional learning model were effective that students understand the mathematics concepts, and learning using discovery learning model was more effective than conventional learning model when viewed from students understand the mathematics concepts.

Abstract

Sekolah Penggerak is a school that implements an independent curriculum. SMP N 4 Patuk is one of those who are included in the first batch. End of school year activities must provide reports on student learning outcomes and confirmation of grade promotion. The first batch of driving schools have not found examples or best practices in compiling the document. Thus, there is a need for mentoring and strengthening of the learning committee in completing grade promotion documents. This is the basic foundation for the implementation of service and is carried out through three steps, namely preparation, implementation, and closing. At firts stage, the team communicated for permits from both schools and universities. In addition, the service team prepares materials related to the preparation of learning outcomes reports. Next is the implementation stage, the team conveys the material and then continues with discussions. In the last stage, which is closing, the servant conducts a simulation of filling out report for the Projek Profil Pelajar Pancasila activities. The results of the service activities for the learning committee showed an increase in the understanding and enthusiasm of the teachers in driving the transformation of the Sekolah Penggerak

Abstract

Lack of access to information about writing scientific papers, classroom action research and numeric literacy. This causes a lack of professional teachers who produce scientific papers, classroom action research and numeric literacy. PGRI Yogyakarta University is one of the universities that has a professional education program department, there are still several professional teachers who have not written scientific work. classroom action research and numeric literacy. Even though there are already professional teachers who have carried out the writing of works. There are still many teachers who are too busy teaching and preparing material every day which means teachers no longer have time to write work. Based on these problems, the method used is an academic seminar to increase teacher professionalism through scientific work, classroom action research, and numeric literacy. The results of the analysis stated that there were changes that occurred in teachers after participating in academic seminar activities. An understanding of the professionalism of elementary school teachers through writing scientific papers, classroom action research and numeracy in learning which was previously ignored makes writing works interesting. Keywords: teacher professionalism, scientific work, classroom action research, numeracy literacy

Abstract

The purpose of this study was to determine the effect of mathematical reasoning ability and student interest in learning on student learning outcomes. This research was conducted at SMP N 7 Yogyakarta in the 2023/2024 school year. Sampling in this study used the Simple Random Sampling technique and obtained the research samples, namely class VII B and VII C. This type of research is correlational research. Data collection used in this study was a description test and questionnaire. The data analysis technique used multiple linear regression analysis to determine the effect of mathematical reasoning ability and student learning interest on student learning outcomes. The results concluded that mathematical reasoning ability (X1) and interest in learning (X2) simultaneously (together) affect learning outcomes (Y) by 19,5%. While the rest is influenced by variables that are not studied.
