This article aims to describe the application of Think Pair Share (TPS) cooperative learning models to improve students 'mathematical connection abilities on derivative material. The mathematical connection indicators in this study are (1) the ability of mathematical connections between mathematical topics, (2) the ability of mathematical connections with other subjects, (3) the ability of mathematical connections with problems in daily life. This research is a class action research (CAR) conducted in class XI-G4 SMA Negeri 5 Malang in two cycles. The first cycle was carried out in five meetings, four meetings for the implementation of learning and one meeting for the final test of the first cycle. Whereas in the second cycle held in five meetings, namely four meetings for the implementation of learning and one meeting for the final test of the second cycle. The results of the research showed that an increase in students' mathematical connections from cycle I to cycle II was indicated by an increase in the grade average and the percentage of completeness in class learning. The classical average in cycle I was 82.79 and increased by 8.56 to 91.35 in cycle II, and the percentage of completeness in cycle I was 70.59% from 34 students and increased by 11.76% to 82.35% of 34 students in the second cycle.

Mathematical connections are connecting mathematical concepts and mathematical concepts with other sciences and problems of everyday life. Mathematical contextual problems can be used to view and build students' mathematical connections. The purpose of this study was to describe how the mathematical connection abilities of junior high school students when solving contextual problems on set material. The type of research used is qualitative descriptive research. Research data obtained through mathematical connection tests and interviews. Analysis of mathematical connection ability is divided into modeling connections, concepts, representations, and procedures. The results of this study indicate that high mathematical ability students make modeling connections by making mathematical models, conceptual connections by connecting many members of each set, and procedural connections by operating algebraic forms correctly, representation connections are not carried out because students rarely use Venn diagrams. Students who are mathematically capable are not making modeling connections, concept connections, representation connections, and procedural connections. Students with low mathematical ability do not make modeling connections, concept connections, representation connections and procedural connections

The ability of geometry is an aspect that underlies students to solve geometry problems. Several studies have stated students' difficulties in learning geometry. There are five levels of expansion of Van Hiele's theory, namely level 0, level 0.5, level 1, level 1.5, and level 2 which are used to measure the geometry abilities of junior high school students. Students' low geometry skills can be improved through scaffolding, so an appropriate scaffolding design is needed. This study aims to describe the appropriate scaffolding design based on the geometry ability test of junior high school students in terms of the expansion of Van Hiele's theory. The research subjects in this study consisted of 3 students of class VIII of SMP Negeri 8 Malang divided into 3 different levels of geometry ability, namely level 0, 0.5, and 1. Data collection methods consisted of written tests and interviews. The results showed that students at level 1 needed scaffolding to be able to connect the properties between quadrilateral shapes. Students at level 0.5 require scaffolding in the form of conceptual understanding of prerequisite materials. While students at level 0 need scaffolding to minimize the prototype phenomenon.

This study aims to describe the response of student teacher candidates to learning using the Gallery Walk method on linear program material. The method used is to apply the Gallery Walk model in the VC class of Malang State University, amounting to 29 participants in one meeting, and collecting the participants' opinions with a response sheet that will be filled out by participating students. The results show that the participants are interested in using the Gallery Walk model but they feel that the use of the Gallery Walk model does not help participants to remember the material for a long period of time.
