A number of national and international scale surveys showed that the mathematics achievements of Indonesian secondary school students were in the lower level. One of the indicators of this low achievement was the insufficient level of understanding of mathematical concepts of the students. Understanding of mathematical concepts could be integrated through Realistic Mathematics Education (RME). Therefore, the quasi-experimental study was conducted to examine the effectiveness of Realistic Mathematical Education towards the conceptual understanding of linear programming. The study also investigated the relationship between conceptual understanding and mathematics achievement and investigated the misconceptions on linear programming. This study involved 65 students of Madrasah Aliyah Negeri 1 Pekanbaru, Indonesia. Test conceptual understanding programming topics had Cronbach's alpha reliability of 0.80. The data were collected by using a test question conceptual understanding of linear programming. Quantitative data analysis involved a descriptive and inferential analysis using SPSS 21.0. The descriptive analysis included the percentage, mean and standard deviation while inferential analysis involving independent t-test and Pearson correlation analysis. The results revealed that there were significant differences between the treatment and control groups toward conceptual understanding. There was a significant relationship between conceptual understanding and mathematics achievement of linear programming. Misconception toward linear programming for the treatment group was lower than the control group. The implications of this study were useful for educators to help their students to understand concept of mathematics through open and contextual questions so that the students though through the mathematics, not worked in the mathematics.

This study examined the validity and reliability of achievement goal instruments to determine the nature of achievement goals for Indonesian students in mathematics education programmes. A total of 538 students participated, selected by using cluster random sampling. A survey design was employed to investigate the factor structure of the achievement goals. Quantitative data were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) using SPSS 23 and AMOS 18. EFA revealed similar structures from prior research and the present study. The CFA approach verified the questionnaire of achievement goal was satisfactory for Indonesian students' context. It also confirmed Indonesian students in mathematics education programmes adopt other-avoidance and self-approach goals. This work concludes the achievement goals of Indonesian university students have a six-factor structure. These findings imply the greater importance of validating and confirming the structure of pupils' achievement goals relative to translating a construct into a different language.

The present research examines the relationship between self-directed learning and SNS that may affect lifelong learning. In study, 170 of the respondents are Masters students and 140 are PhD students in Malaysia. The study follows a relational survey to investigate and measure the degree of relationship amongst self-directed learning, SNS and lifelong learning. The findings of the research corroborate that self-directed learning positively affects lifelong learning. SEM analysis indicates significant and positive influence of self-directed learning on SNS. SNS are a positive partial mediator between self-directed learning and lifelong learning. In conclusion, self-directed learning positively influences the lifelong learning of students, which is affected by SNS. This study implies that lectures should support preservice teachers to sharpen teachers' self-directed learning and social networking in lifelong learning by giving suitable learning methods and proposing a sufficient teaching and learning atmosphere.

This study examined the validity and reliability of PERMA instruments to determine the nature of PERMA for Indonesian students in mathematics education programmes. A total of 274 students participated, selected by using cluster random sampling. A survey design was employed to investigate the factor structure of the PERMA. Quantitative data were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) using SPSS 23 and AMOS 18. EFA revealed similar structures from prior research and the present study. The CFA approach verified the questionnaire of PERMA was satisfactory for Indonesian students' context. This work concludes the PERMA of Indonesian university students have a five-factor structure. These findings imply the greater importance of validating and confirming the structure of students' PERMA relative to translating a construct into a different language.

This study investigates the relationship between metacognition and achievement goals which may influence mathematical modeling competency in students of mathematics education programs. The current study employs 538 students of mathematics education program; 483 (89.8%) of whom are male and 55 (10.2%) are aged from 18 years old to 22 years old. The study follows a correlational research design to investigate and measure the degree of relationship amongst mathematical modeling competencies, achievement goals and metacognition. Results indicate that achievement goals and metacognition positively influence mathematical modeling competency. Moreover, four metacognition dimensions including awareness, planning, cognitive strategy and self-checking are positive partial mediators because they increase the association between achievement goals and mathematical modeling competency. In conclusion, metacognition and achievement goals positively affect students’ mathematical modeling competency.

The research presented in this article is a systematic review of the literature on the assessment of mathematical modeling in the setting of mathematics education published in the previous five years. This research has compiled the current best information from around the world to offer an overview of the assessment of mathematical modeling for pre-service mathematics teachers or mathematics teachers. We followed the approach used in Joklitschke et al. ( 2021), which involved 10 steps in systematic literature review (SLR). We accessed using Web of Science (WoS), Scopus, and mathematics education journals that are ranked 1-10. Based on a full-text analysis of 18 peerreviewed papers published in English, most of the research was conducted among pre-service mathematics teacher and most of the studies were conducted in Turkey, United States, and Germany. The future trends and opportunities were also discussed. We also found that most test types employed for measuring modeling competency were project, cognitive dimension, holistic approach, and the tests utilized more qualitative approach.

This article aims to analyze the development of Islamic education in Indonesia and efforts to strengthen it in the national education system. This type of research is descriptive qualitative. The study of literature by focusing on terms of peeling, summarizing and collecting a literature, then the authors provide an analysis of the data that has been collected. The results showed that during the pre-independence era religious education was not only not recognized but also not included in the education system, it was even suspected of being a place to incite and fight the invaders. At the time of independence it did not yet have a role because the government still tended to be controlled by nationalist and secular groups, if there were Islamic groups, Islam was still more abangan. Thus the New Order government continuously fostered the quality of madrasa education so that in 1975 a joint decree (SKB) was issued by three ministers on Improving the Quality of Education in Madrasas, where the SKB of the three ministers had advantages and disadvantages. So that the solution of this weakness is the government is trying to make breakthroughs to restore the function of the madrasa as a place to print religious leaders, namely by opening an alternative Madrasah Aliyah named Madrasah Aliyah Special Program (MAPK). Henceforth, this MAPK was changed to Madrasah Aliyah Religious (MAK) which focuses and strengthens the field of Islamic education. There are two strengthening of Islamic education in the national education system, namely strengthening Islamic educational institutions, and strengthening religious subjects in all schools both under the auspices of the Ministry of Religion and other Ministries.
