This research is a descriptive qualitative research conducted on students of Informatics Engineering Study Program. The sample used was 120 students in the second semester who were selected by purposive sampling. The purpose of this research is to find out the extent of students communication ability in the application of matrices in the field of informatics.
Data collection in the form of assignments in the form of a paper about the application of the matrix in the scope of informatics engineering. Data analysis to measure mathematical communication ability is done in two ways, namely the assessment of the content or content of papers that fit the criteria, and student presentations explaining the results of the paper. In addition, interviews were also conducted with students regarding the application of the matrix. After being analyzed, it is obtained that the mathematical communication ability of students are quite good. Most of the students have understood and can communicate matrix material with its application in Informatics Engineering.
But students have not been able to apply it independently because students have not studied programming material further.

The study was a quasi-experimental study with a pretest-posttest control group design.
This study aims to look at the effect of peer tutoring approaches to thinking algebra in primary school teacher candidates for the 2019/2020 school year at the Universitas Mataram, Indonesia. The sampling technique in this study was selected by cluster random sampling. This study uses a control class of 37 people who received conventional learning and an experimental class of 35 people who received learning using a peer tutoring approach. The implementation of the peer tutoring approach in the experimental class uses small groups where each group has a tutor. Data analysis techniques in this study used the analysis of covariance (ANCOVA) test, N-gain analysis, and analysis of the description of the results of the answers. The instrument used in this study was an algebraic thinking ability test in the form of essay questions.
ANCOVA test results show that the significance value of the count is 0.001 (<0.05), then H0 is rejected. This means that there is a significant influence on the algebraic thinking skills of primary school teachers candidates who are taught using the peer tutoring approach. The significance value of N-gain has a value of 0.00 (<0.05). This means there is an increase in the algebraic thinking skills of primary school teachers candidates who are taught using the peer tutoring approach. The results of the analysis of the description of the answers also show primary school teachers candidates who use the peer tutor approach are able to master indicators of algebraic thinking better than primary school teachers candidates who use conventional learning.

The degree of alignment of the major elements of an educational system such as intended outcomes or standards of a course, instructional materials, and assessment materials contribute to the achievement of the understanding of students in courses like mathematics. Considering the standards from the 2010 Mathematics Framework for Philippine Basic Education (MFPBE) and the College Readiness Standards (CRS) that were utilized in creating the K-12 Mathematics Curriculum Guide (MCG), it is appropriate to study the extent to which the test items from periodic exams reflect the important objectives and standards of a particular content strand. Using a content analysis method, this study determined the degree of alignment between the Geometry test items from the junior high school periodic exams for school year 2017-2018 and the Geometry Objectives and Standards from the MFPBE and CRS. The extent of the alignment of 313 Geometry items with the MFPBE Geometry Objectives and CRS of CHED was determined using the Depth of Knowledge (DOK) criterion by Webb (2007). Findings of this study showed that the overall level of alignment of the geometry test items with the geometry objectives from the MFPBE and the geometry performance standards from the CRS is poor. Also, results show that the geometry test items given to junior high school students had little to no emphasis in terms of the integration of algebra and geometry. This study suggests that test items should not be limited to multiple-choice type of questions but should include routine and non-routine problems requiring student solutions.
