Abstract

Every individual has different abilities in translating problems because it is influenced by basic knowledge, experience, and cognitive. The cognitive types of FD were identical slower than others. This study describes the mathematical reasoning of students with cognitive type of FD in problem solving. The research data needed is the GEFT test, problem-solving tests, and interviews involving twostudents in level IV . All data were analyzed inductively. The results showed that students with the cognitive type of FD needed a long time to create connection to the problem thinking and they needed direction as a stimulus to stimulate their thinking. Lecturers can use realistic examples in the environment around them to make connections in their thinking.

Abstract

PBL adoption is increasingly widespread and recognized for various disciplines in higher education and in basic education has made a trend in learning innovation today. PBL provides individual freedom to find, utilize, build knowledge through experience in the form of project completion. The characteristics of the project used are the existence of investigations that give students the freedom to change and build knowledge. The investigation took place every day in a row from the student team (2 people) for 4 days for the given calculus project. The results of project completion investigations were delivered through team presentations, discussions, interviews with lecturers, and the provision of scaffolding by lecturers.Investigation which success include combination, definition of maclaurin series, tribe and series and derivative function which support project finishing, describing material supporting of project through example,verification binomial theorem, identification to 30 tribes maclaurin series/binomial series and approach value through tool of conting/ software(excel,calculator,geogebra) Scaffolding thinks incompatibility occurs in understanding and interpretation of combination notation, thought theorem, and implementation in calculations. Researcher's discovery that students are very active in building knowledge and exploring their experiences, as well as building openness in teams and instructors.
