“…The results show that implementation of RBL results in more effective compared with the conventional learning model. This result is in line with Sutarto's research result stating that generalization process is very important to solve the pattern of numbers (Sutarto, et al, 2018). Sota & Peltzer report that the application of RBL among master-degree students when dealing with reading, analysing, synthesising, and presentation as well as discussion can improve cognitive skill, knowledge, ethics, competence, social skills, communication, arithmetic and information technology skills, and satisfaction in finding information, which are all found at high extent (Sota 2017).…”

The present study aims to investigate the effectiveness of Research Based Learning (RBL) in improving students' learning achievement in solving two dimensional arithmetic sequence problems. The study applied triangulation method including qualitative and quantitative methods. The research subjects were 4thsemester students of higher education. The quantitative method was applied to analyse the learning achievement test, while the qualitative one was applied in the form of observation and interview. The collected data were analysed by using inferential statistics t-test. The result of t-test indicates that the sig (2-tailed) of independent sample t-test of pre-test is 0.853 (p>0,05), thus it is not significant. It implies the two classes are homogeneous in term of student achievement test. The data analysis of independent sample t-test of post-test, the sig (2-tailed) is 0.00 (p=<0,05), thus it is significant. It implies that the student achievement tests of two classes are different after the implementation of RBL. It shows that the students' achievement result of experimental class is better than the control class. The implementation of RBL is proven effective in improving students learning achievement in solving two-dimensional arithmetic problems.

“…Then, the subject in the category of compositional functional thinking processes in organizing data by making lists. This is in accordance with Sutarto et al (2016), who indicate that the strategy used in organising particular cases is by making lists. Meanwhile, in the semicompositional category, organising data is done through tables.…”

Background: Every student has the ability to think, especially the ability to think when solving mathematical problems. The teacher must explore this ability to determine student understanding of the material being taught. Functions are essential because they are the basis for understanding algebra. The way of thinking about function is called functional thinking. Objective: This study aims to investigate the functional thinking process of students in solving mathematical problems based on the APOS theory. Design: This type of research is qualitative through an exploratory, descriptive approach. Setting and participants: Two out of 44 university students that can communicate fluently when working on questions using the think-aloud and interview methods. Data analysis: Analysis of students' functional thinking processes using the triangulation method, namely comparing think-aloud data, student answer sheets, and interview results. Results: This study found two ways of student functional thinking processes, namely semi-compositional functional thinking processes and compositional functional thinking processes, where students can generalise the relationship between quantity variations in the form of a composition function. Conclusion:This study investigates the functional thinking process of students in exploring the understanding of the concept of function so that students are expected to be able to represent and generalise function forms.

“…Arnon et al, (2014) and Syamsuri, Purwanto, Subanji, & Irawati, (2017) explains that APOS theory involves mental structures, such as action, process, object, and scheme which are connected to mental mechanism which consists internalization, coordination, reversal, encapsulation, de-encapsulation, and thematization. It is in line with Sutarto, Nusantara, Subanji, Hastuti, & Dafik (2018) explaining that APOS theory involving action, process, object, and scheme.In this research, the researchers gave students problems. Then, their thinking processes were reviewed by APOS theory and it was seen in term of their mathematical communications.…”

Role of mathematical communication in learning is needed. Mathematical communication could carry conceptual understanding, problem solving, and mathematics reasoning. This research aims to explain communication process of Junior High School students in solving problems based on APOS framework theory. In solving mathematics problem at school, it emphasizes more on outcome than process without considering students' reasoning process. To express mathematics ideas, the learning seems to emphasize on written than spoken. To solve that problem, there is a need of mathematical communication process connection to students' reasoning in solving problems. The reasoning skill of the students was reviewed based on APOS Theory. This research is a qualitative research. The instruments of collecting data were problem solving task and interview. The results showed that there were 10 students performing mathematical communication process by having pseudo drawing communication and 20 students by having pseudo mathematical expression communication criteria.
