Abstract

The education dharma program states that lecturers have the main task of administering education. Permenristekdikti No. 44 of 2015 states the minimum criteria for the learning process, namely CPL (Graduate Learning Outcomes). CPL requires student-centered learning and the role of the lecturer as a facilitator so that Student Center Learning (SCL) is created. Real Analysis 2 which is a follow-up course from Real Analysis 1. Real Analysis 2 is a pure mathematics course that contains a collection of definitions and theorems and lemmas that involve proof. So far, learning real analysis is difficult for students to accept, namely making connections between one rule and another. One learning model that facilitates students to fulfill the CPL for Real Analysis 2 course is the PjBL (Project Based Learning) model. PjBL implementation must be supported by adequate learning facilities. Therefore, a module based on the PjBL model is needed. The use of this PjbL-based module is expected that students will be able to solve mathematical problems and support the fulfillment of CPL courses which results in the formation of creative and systematic mathematics students who are good at solving problems and have the capabilities and competencies needed by the world of work.

Abstract

This study aims to identify the characteristics of elementary school students' analogies in proposing area problems. The method used in this research is descriptive qualitative using a case study approach. The characteristics of analogy in the submission of area problems can be categorized into three: (1) Identical-reformulation is rearranging the elements in the problem structure in ways that do not change the nature of the problem. (2) Identical-different-reconstruction is modifying and maintaining some elements of the form in the initial problem so that the resulting problem looks slightly different. (3) Different-imitation is changing and adding new shape elements that are not in the initial problem to produce a different problem. The results of the research showed that the characteristic most often found in students is imitation, where the problem produced is different from the initial problem given. So the different imitation characteristics that appear most often correspond to replacement characteristics, namely the problem posing product based on the initial problem or source problem by changing the context of the problem, namely changing the shape of the cake slice.

Abstract

Students' mathematical learning results are influenced by many variables, including students, parents, schools, curricula, and mathematics itself. Preliminary observations showed that 27.7% of students received a score above 75 and 72.3% received a rating below 75. The minimum score for the exam was 75, which is the average grade. Many factors can contribute to poor student learning outcomes, including the role of teachers as instructors and their influence on students in creating and using inappropriate learning strategies. An alternative that can be developed on a model with learning is to use a mind mapping defence model. This survey aims to find out how much influence it has found on the mind mapping defense model with the help of power points. The type of quantitative research used in this study is the design of a single group pretest-posttest. The test results are known to have a thitung value of 3.27.
