Mathematics Dissemination of Covid-19 in School Learning Susila Bahri University of Andalas Abstract The teachers^ lack of knowledge about the use and use of mathematical formulas and concepts in solving problems in everyday life results in students not knowing the role, benefits, and importance of mathematics material taught by teachers in schools. As a result, students often perceive mathematics as only theoretical, difficult, boring, and uninteresting to learn. Determining the number of people infected with Covid 19 in schools in the future is one of the problems that can be modeled mathematically. The dynamic system model In+1=1,1177482 In - 0,000196247 In2 that can be used to predict the number of infected students in the next few days is constructed with the assumption that there is an interaction between students and students who are vulnerable to the Covid virus. A model that uses the concept of change = future value - present value and the proportionality relation is constructed through several stages or modeling steps. These stages are problem identification, making assumptions, determining variables and relationships between variables, constructing models or mathematical equations, determining the solution of the model, and testing the validity of the model. From the results of the validity test, it was found that the model was closed to the data. This means that the model constructed can be declared valid. Besides, from the resulting model, it can be concluded that the mathematics material taught in schools and related to Covid 19 is quadratic equations, functions, and sequences. From this activity, the teacher can also find out the application of some of the mathematics material taught so far. Then this knowledge can be passed on to students at school.

However, the use of technology such as online platforms or mathematics software in PBL for students^ MCTS still seems to be rarely conducted. To summarize and estimate the effect of technology-assisted PBL on students^ MCTS, and investigate some factors such as technology type, sample size, education level, treatment duration, and mathematics material that have the opportunity to cause the heterogeneous effect size, we employed meta-analysis with the random effect model. In addition, we selected Hedge^s equation to measure its effect size and used Comprehensive Meta-Analysis (CMA) software as a calculation tool. From seven primary studies synthesized, this study revealed that the overall effect size of technology-assisted PBL implementation on students^ MCTS was g = 0,962 and it was categorized as a moderate effect. Moreover, technology-assisted PBL implementation was able to cultivate significantly students^ MCTS. Furthermore, some factors investigated did not cause significantly the heterogeneous effect size. Thus, this study suggests mathematics teachers that they should apply technology-assisted PBL in mathematics learning as one of the best solutions to cultivate the low students^ MCTS.

In addition, we used Hedge^s formula to measure the effect size and employed Comprehensive Meta-Analysis (CMA) software as a calculation tool. The result revealed that the overall effect size of PjBL implementation in cultivating students^ MCTS was g = 0,610 (moderate effect). Moreover, the implementation of PjBL could cultivate significantly the students^ MCTS. Furthermore, education level was one of the study characteristics that created significantly the heterogeneous effect size of PjBL implementation on students^ MCTS. This study recommends mathematics teachers that they should select PjBL as one of the alternative mathematics learnings to be implemented in mathematics classroom in cultivating the students^ MCTS.

Does discovery learning enhance secondary students mathematical critical thinking skills? Yohannes Yohannes(1*), Dadang Juandi(2), Jarnawi Afgani Dahlan(2) (1)Mathematics Education, Graduate School, Universitas Pendidikan Indonesia, Jl. Dr. Setiabudhi No. 229, Bandung 40154, Indonesia (2)Mathematics Education Department, Graduate School, Universitas Pendidikan Indonesia, Jl. Dr. Setiabudhi No. 229, Bandung 40154, Indonesia *yohannesyohannes[at]upi.edu Abstract The implementation of the Discovery Learning (DL) model in mathematics learning in Indonesia is believed to improve secondary students mathematical critical thinking skills so that it becomes the recommended learning model in the national curriculum. Several previous similar types of research have found that DL can enhance secondary students mathematical critical thinking skills. However, there were inconsistencies in the effect size of these primary studies. The meta-analysis was carried out to obtain a comprehensive and inclusive centralized analysis result and investigate the effect of study characteristics. Comprehensive Meta-Analysis (CMA) is a tool used to calculate hedges effect size (ES). An analysis of 25 relevant primary studies that met the inclusion criteria revealed that, based on the random-effects model, the implementation of the DL model had a high positive effect (ES = 0.981) on secondary students critical thinking skills compared to the conventional model. Furthermore, the characteristics of the duration of treatment and indexed publication show a significant difference in effect size of DL implementation on students^ mathematical critical thinking skills. Thus, DL becomes a recommended model for use by secondary school teachers to improve students mathematical thinking skills by considering the influential characteristics of the study.

The effect of problem-oriented teaching method on mathematical critical thinking skills of students Raden Nabilah Fahrani (a*), Turmudi (a), Maifalinda Fatra (b), Finola Marta Putri (b) a) Departemen Pendidikan Matematika, Universitas Pendidikan Indonesia, Jl. Dr. Setiabudi No. 229, Bandung 40154, Indonesia *nabilahfahrani[at]upi.edu b) Program Studi Pendidikan Matematika, Universitas Islam Negeri Syarif Hidayatullah Jakarta, Jl. Ir. H. Djuanda No. 95, Tangerang Selatan 15412, Indonesia Abstract Mathematical critical thinking skills are beneficial for students to face the challenges in society 5.0 era. This research aims to analyze the effect of the problem-oriented teaching method on the mathematical critical thinking skills of students. To reach this aim, we set up this quasi-experimental research using a randomized control-group post-test-only design. All eighth-grade students in one of the junior high schools in Bogor were research population with fifty-seven students from two classes as research sample selected by purposive sampling technique. The results showed that the mathematical critical thinking skills of students who were treated in the form of learning using the problem-oriented teaching method were significantly higher than students who were given learning using the scientific approach with average scores of 25.43 and 14.84. It implies that the implementation of the problem-oriented teaching method positively affected the mathematical critical thinking skills of students. In addition, that effect had a large meaningfulness measure in practical level with an effect size value of 1.2. So, we conclude that the problem-oriented teaching method can be implemented to facilitate students to improve their mathematical critical thinking skills. We suggest that future researchers consider the affective skills of students to be more comprehensive.

How Do Emotional Intelligence and Self-efficacy Predict the Mathematics Learning Achievement of Students during Pandemics? Chelsi Ariati (a*), Vera Anzani (a) a) Departemen Pendidikan Matematika, Universitas Pendidikan Indonesia, Jl. Dr. Setia Budhi No. 229, Bandung 40154, Indonesia *chelsiariati[at]gmail.com Abstract The achievement of pupils in both external and internal examinations is deterioration. Psychological variables such as emotional intelligence and self-efficacy have frequently been overlooked in research on factors impacting student progress in mathematics. The goal of this study was to see how students^ emotional intelligence and self-efficacy affect their mathematical achievement. A correlational survey study methodology was used with 140 senior high school students from one of Riau^s senior high schools. Data was gathered using emotional intelligence, self-efficacy questionnaires, and a report on students^ academic progress. The data was analyzed using simple linear regression analysis. This findings revealed that emotional competence and self-efficacy were important predictors of students^ mathematical success in the case of self-efficacy but not in the case of emotional intelligence. It was suggested that students be taught how to improve their emotional intelligence and self-efficacy through various techniques.

Students^ Adaptive Reasoning in Solving Pythagoras Theorem Viewed by Gender Khaluka Ahsana Fitri*, Sufyani Prabawanto, Endang Cahya Mulyaning Universitas Pendidikan Indonesia Abstract Adaptive reasoning is one of mathematical proficiency strand. It refers to the capacity of reflecting, explaining, justifying, and thinking logically about concepts and situations. It helps students in constructing their idea in solving mathematical problems. In the other hand, some previous studies stated that gender significantly influence student mathematical proficiency. This study was carried out to analyze students^ adaptive reasoning in solving Pythagoras Theorem problems viewed by gender. There were 31 students participated as the subject in this study- 14 males and 17 females. They were the second grade of two senior high schools in South of Aceh. There were several steps in conducting this study- formulating the problems, validating problems, conducting the test, and interview. The problems were formulated based on the adaptive reasoning indicators and curriculum. Then they were validated by two lecturers and a teacher. Furthermore, the test was carried out during 20 minutes for answering 4 problems. Afterword, the interviews were held for several students to clarify and ensure their answer on the test. This study showed that most of female students had average score of adaptive reasoning in solving Pythagoras Theorem, whereas male student tend to have the highest or the lowest score in the class. Based on this study, it was recommended that future studies to investigate all the strands of mathematical proficiency and involves a large numbers of students.

Students Mathematical Refractive Thinking Skills in Research Based Learning (RBL) reviewed from Adversity Quotient (AQ) Rosa Mery Christinove Program Pascasarjana, Universitas Negeri Semarang, Jl. Kelud Utara III, Semarang 50237, Indonesia rosamerychristinove[at]students.unnes.ac.id Abstract Mathematics is one of the subjects that exist since elementary education and can form a systematic, logical and critical way of thinking. But in reality, there are still students who have difficulty in building a way of thinking. While the way of thinking that is currently required by students is high-level thinking. Two interrelated dimensions of high-level thinking are reflective thinking and critical thinking which is then referred to as refractive. Refractive thinking is a thought process that starts from reflective thinking constructed with critical thinking that can result in problem decisions. In problem decision making can be reviewed also through one aspect of psychology, namely Adversity Quotiont (AQ). AQ has 3 levels namely Climber, Camper and Quitter with their respective characteristics especially in solving math problems. So a learning model is needed that can facilitate students to be able to develop refractive thinking processes reviewed from AQ. The learning model that uses and selects learning resources according to needs is the Research Based Learning (RBL) model. This model can be done by engaging students in identifying questions, planning steps to search, collect, use, synthesize and evaluate information. The use of RBL is intended so that students can develop their refractive thinking skills in solving a math problem that is adjusted to each studens AQ level.

Mathematical Creative Thinking Ability reviewed by Metacognition assisted by E-Module Alfadeo Adi Putratama (a*) Program Pascasarjana, Universitas Negeri Semarang, Jalan Kelud Utara III, Semarang 50237, Indonesia alfadeo[at]students.unnes.ac.id Abstract Mathematics is a subject that is considered difficult by most students, so that teachers are required to innovate in implementing mathematics learning in the classroom so that students^ creative thinking abilities develop. Creative thinking is a new perspective for observing and working on a problem based on four aspects, namely fluency, flexibility, originality, and elaboration. The creative thinking process cannot be separated from the planning, monitoring and evaluation which are metacognition reviews. So it is necessary to develop mathematical creative thinking skills in terms of E-Module assisted metacognition, with the hope of developing students^ mathematical creative thinking skills by learning through interactive E-Modules and guiding students to think creatively. The use of E-Modules also makes students independent of the teacher and uses students^ thinking abilities to the fullest so that creative ideas emerge in solving problems. The use of the E-Module assisted metacognition review is intended to review the planning, monitoring and evaluation that students do in solving problems in the E-Module using a new perspective so that their creative thinking skills develop.
