Arbitrage Pricing Theory (APT) is a pricing model that can be used to determine the expected return of a security. It assumes that there is more than one factor affecting the expected return. The risk of APT is part of the sensitivity of macroeconomic factors to return security. The identification of factors that affect security returns is one of the most important stages of APT modeling. This is because the APT does not specify how factors affect the return on a security. One method that can be used to identify macroeconomic factors is Vector Autoregressive (VAR). An overview of the relationship between return security and macroeconomic factors analyzed using VAR by going through the stages of checking the stationary data, determining the optimal lag length, testing Granger causality between variables, estimating the VAR model and Portmanteau diagnostic test, compiling the APT equation and calculating the expected stock return from APT models. Based on the results of the study, we conclude that at a significance level of 5%, only INDF shares show Granger causality with macroeconomic factors, such as the BI rate, money supply, and world oil prices. Furthermore, the Arbitrage Pricing Theory (APT) model implies that the expected return on INDF stock is lower than the actual return. This means that INDF's stock is undervalued, which means that future stock returns will be lower. Keywords: Vector Autoregressive (VAR), Arbitrage Pricing Theory (APT), Syariah Stock Return

The emotional intelligence of students is an essential aspect in achieving learning results, particularly in mathematics. This study intends to identify the impact of parental supervision and learning motivation on mathematics learning outcomes at Wahid Hasyim 8 Waru Middle School in terms of high, medium, and low emotional intelligence. This research utilizes quantitative research methods by doing ex-post facto. In collecting data, the researcher uses surveys and documentation. The questionnaire instrument contains three questionnaires, including a parent guidance questionnaire, a learning motivation questionnaire, and an emotional intelligence assessment. While documentation is used to collect statistics on student learning outcomes, it also serves as a means of communication between instructors and students. The results of hypothesis testing from the results of parental guidance and learning motivation on student learning outcomes are reviewed in terms of high emotional intelligence with an F count of 40,661 and an F sig of 0.024, moderate emotional intelligence with an F value of 5.288, and an F count of 0.010, and emotional intelligence with an F value of 7.073 and an F sig of 0.049. The association between mathematical learning results, parental supervision, and learning motivation in terms of emotional intelligence might be described as good and significant.

Reflective abstraction is an activity to construct mathematical concepts through similarities and combinations of existing structures and reorganized into four levels: (1) recognition, (2) representation, (3) structural abstraction, and (4) structural awareness. Each individual has different characteristics of cognitive style in processing information. Differences in cognitive style affect the individual's ability to understand the problem. This study aims to describe students' level of reflective abstraction in solving mathematical problems in terms of field-independent (FI) and field-dependent (FD) cognitive styles. This research is a qualitative descriptive study. Task-based interviews carried out the data collection technique. The results are that field-independent (FI) students can correctly perform all levels of reflective abstraction in the stages of solving mathematical problems, but field-dependent (FD) students can only do abstraction on the introduction and representation.

The purpose of this study was to describe students' geometric thinking skills on circle material based on Van Hiele's theory (Visualization, Analysis, Informal Deduction, Deduction, Rigor). The subjects of this study were 3 students of class IX-A SMP Hang Tuah 4 Surabaya based on their initial mathematical abilities (high, medium, and low). The initial mathematical ability data was obtained from data on report cards for the even semester of the 2021-2022 academic year and based on the considerations of the mathematics teacher for class IX-A. This type of research is descriptive qualitative research. Collecting data in this study used tests and interviews. The test instrument used in this study was a circular geometry test in the form of mathematical questions with circle material arranged based on the Van Hiele indicator without stage 4 (Rigor) with the consideration that the research was conducted in class IX SMP so students have not been able to understand the material at stage 4 (rigor). Student with high initial mathematical abilities, geometric thinking abilities is already at stage 2 (informal deduction). Student with medium mathematical abilities, geometric thinking skills is at stage 2 (informal deduction). Student with low mathematical abilities, geometric thinking skills is at stage 0 (visualization).

Improving math skills is considered important today. Because mathematical abilities can encourage individuals to be able to solve problems in the midst of society. A number of studies have proven that self-concept is very influential on mathematical ability. Therefore, this study wants to prove again whether self-concept and interest have an effect on mathematical ability. In order to prove this question, this study uses a quantitative type of research with an ex-post facto research approach. The sample in this study amounted to 24 students (male = 3 and female = 21). The instrument used in this study is the self-concept and interest scale adapted from Sproesser et al (2016) and individual mathematical abilities were taken from the Grade Point Average. This study uses linear regression analysis techniques. The results showed that self-concept is very influential on the mathematical ability by 0.04 (p<0.05). That is, to improve the individual's mathematical ability must have self-concept maturity and interest in mathematics.Keywords: self-concept, mathematical ability, ex-post facto research

That is, to improve the individual's mathematical ability must have self-concept maturity and interest in mathematics.Keywords: self-concept, mathematical ability, ex-post facto research","PeriodicalId":55794,"journal":{"name":"MaPan Jurnal Matematika dan Pembelajaran","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89006391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
