PEMBELAJARAN MATEMATIKA SMP DENGAN PENDEKATAN APTITUDE TREATMENT INTERACTION BERBASIS PORTOFOLIO

Abstract

This research and development aimed to compile model study of mathematics in
SMP with interaction treatment aptitude (ATI) approach based on portfolio. Data
is e collected by observation, interview, and FGD. The research participation is
teachers, students, educationist, and policy makers. This research is located in four
public SMP and four SMP private sector of Surakarta. The data is analyzed using
interactive cycle of data collecting, reduction data, data presentation, and
withdrawal of verification or node. The research findings can be summarized that
the development of mathematics model study with ATI approach based on
portfolio and its activities is started from antecedent phase, central activity phase,
and last activity phase, with the documentation of all students. Third step is
conducted in immeasurable class setting, according to the model of classical,
group, and individual context. A small team learning group which has five
member of students with the difference ability (1 is high, 2 is middle, and 1
