EKSPERIMENTASI MODEL PEMBELAJARAN TTW DAN NHT PADA MATERI BANGUN RUANG SISI DATAR DITINJAU DARI KEMAMPUAN KOMUNIKASI MATEMATIS SISWA
Abstract: The aim of the
research was to find out the effect of learning models on mathematics
achievement viewed from the student mathematics communications ability. The
learning model compared were TTW (Think Talk Write), NHT (Numbered Head
Together) and conventional. The type of the research was a quasi-experimental
by 3 12×"> 3 factorial design. The population was the eight grade
student of junior high school in Magelang regency on academic year 2013/2014.
The sampling tecnique was stratified cluster random sampling. The size of the
sampel was 298 students consisted of 100 students in the first experimental
group, 99 students in second experimental group and 99 students in control
group. The instruments used were mathematics achievement test and mathematics
communication ability test. The data was analyzed using unbalanced two-way
analysis of variance. The conclusions of the research were as follows. (1) TTW
learning model gives better mathematics achievement than NHT and conventional
learning model, and NHT learning model gives better mathematics achievement
than conventional learning model. (2) The students with high mathematics
communication ability have better mathematics achievement than the students
with middle or low mathematics communication ability, the students with middle
mathematics communication ability have better mathematics achievement than the
students with low mathematics communication ability, (3) a. In the students
with high and middle mathematics communication ability, TTW, NHT and conventional learning model give the
same mathematics achievement, b. In the
students with low mathematics communication ability, TTW and NHT learning model
give the same mathematics achievement, but give better mathematics achievement
than conventional learning model, also NHT and conventional learning model give
the same mathematics achievement, (4) a. In the TTW and NHT learning model,
students with high, middle and low mathematics communication ability have the
same mathematics achievement, b. In the conventional learning model, students
with high and middle mathematics communication ability have the same
mathematics achievement, but have better mathematics achievement than students
with low mathematics communication ability, and students with middle and low
mathematics communication ability have the same mathematics achievement.
