Abstract

This article describes students’ mathematical-thinking process in solving PISA-model mathematics -problems. Mathematical-thinking is not only important for academic succes, but is also esssential for developing mathematical reasoning and critical thinking habits in sustainable development for creating better life. In order to achieve the research aims, we used a qualitative approach with descriptive methods. Data were collected using mathematical activities adapted from PISA items. Three students’ works that represent each level of mathematical ability were selected for in-depth analysis. The findings shows that students’ mathematical-thinking ability in solving PISA-model mathematics-problems is determined by how the students go beyond phases of mathematical-thinkng proses (Entry, Attack, Review). Students can solve problems correctly if they are able to go through all phases, although not all aspects of each phase are fulfilled. If students fail in the Entry phase, it is certain that they cannot go through the next two phases properly (Attack and Review).

Abstract

Mathematics is a subject that is disliked by most students. This has resulted in a lot of children who are not enthusiastic about this lesson since elementary school. Elementary school is a place where children start knowing what numbers are, what numbers are and how a number looks. Numbers become the basis for children before learning about mathematics. There are so many branches in numbers that children need to know, starting from the basics of numbers, namely natural numbers, developing into whole numbers, whole numbers, and fractions. This is why the methods of learning mathematics must be well determined, at this time many learning methods have emerged with various criteria. Because of this, the writer tries to find the right theoretical solution according to the number material which has developing properties, the method that can be used is the Bruner Theory, which is to learn by understanding the basics first before proceeding with something that is more difficult because mathematics is an abstract concept.

Abstract

During the Covid-19 pandemic, learning was fully carried out online. However, the implementation of learning is still not optimal, especially in evaluating student activities.Using online learning, lecturers have difficulty observing student activities, and mostly, online learning was done using assignments or even a teacher-centered. This research was expected to accommodate the application of online learning by the student center using the LAPS-Heuristic model. This study aims to describe student activities in the application of online learning using the Logan Avanue Problem Solving (LAPS)-Heuristic model on geometry material. This research uses a descriptive qualitative-quantitative approach. The research steps were carried out, starting from research planning, implementing the LAPS-Heuristic model online, analyzing, and evaluating activities. Student activity data were obtained from observations made by researchers and one observer. Based on the findings in the study, student activities in the application of online learning using the LAPS-Heuristic model on geometry material are described in 7 aspects. The seven aspects are visual, verbal, listening, writing, drawing, calculating / problem solving, and emotional aspects. In learning reflection material online by applying the LAPS Heuristic learning model, the seven aspects of the activity appear very well.
