 Abstract: The objective of this research was to know the effect of the learning models on the learning achievement of quadrangle viewed from the spatial ability of the students. The learning models compared were the cooperative learning model of the TGT type with concept mapping strategy, the cooperative learning model of the TGT type, and the direct learning model. This research used the quasi experimental method. Its population was all of the students in grade VII of State Junior Secondary Schools of Pati regency in Academic Year 2013/2014. The samples of the research were taken by using the stratified cluster random sampling technique. The samples of the research consisted of 325 students. They were grouped into three groups, namely: 109 in experimental group 1, 110 in experimental group 2, and 106 in control group. The instruments to gather the data were test of achievement on the learning topic of quadrangle, and test of spatial ability. The proposed hypotheses of the research were analyzed by using the two way analysis of variance with unbalanced cells. The results of the research were as follows. (1) The cooperative learning model of the TGT type with concept mapping strategy results in a better learning achievement than the cooperative learning model of the TGT type and the direct learning model, but the cooperative learning model of the TGT type results in the same learning achievement as the direct learning model. (2) The students with the high spatial ability had the same learning achievement as those with the moderate spatial ability, but the students with the high spatial ability and those with the moderate spatial ability had a better learning achievement than those with the low spatial ability. (3) In each category of the spatial abilities, the cooperative learning model of the TGT type with concept mapping strategy results in a better learning achievement than the cooperative learning model of the TGT type and the direct learning model, but the cooperative learning model of the TGT type results in the same learning achievement as the direct learning model. (4) In each of the learning models, the students with the high spatial ability had the same learning achievement as those with the moderate spatial ability, but the students with the high spatial ability and those with the moderate spatial ability had a better learning achievement than those with the low spatial ability.Keywords: TGT, concept mapping, and spatial ability.

This study was a quasi-experimental research with 3x3 factorial designs. The population was the students of XI class, State SMA/MA in Ketapang District, West Kalimantan Province in year academic 2013/2014. The samples were taken through stratified cluster random sampling technique. The entire samples were 312 students comprising 101 students for the first experimental group, 108 students for the second experimental group and 103 students for control group. The data were collected through the mathematical achievement tests and the learning creativity questionnaires. The hypothesis testing employed  unbalanced two ways of ANOVA. The results of the study are as follows. (1)  RT produced students? better mathematics learning achievement than PBL and conventional models; PBL produced the same mathematical achievement as conventional model. (2) The students with high learning creativity had better mathematics learning achievement than those with medium and low learning creativity; the students with medium creativity had better achievement than those with low creativity. (3) Treated with RT, the students with high creativity learning  had better mathematics learning achievement than those with medium and low creativity; the students with medium creativity had better achievement than those with low creativity; treated with PBL, the students with high, medium, and low learning creativity had the same achievement; treated with conventional model, students with  high  creativity  had the same achievement as those with medium; the students with high creativity had better achievement than those with low creativity; the students with medium creativity had the same achievement as those with low creativity; (4) Viewed from their high learning creativity, students treated with RT had better mathematics learning achievement than those treated with PBL and conventional  model; those treated with PBL had the same achievement as those treated with conventional model. Viewed from their medium learning creativity, students treated with RT had better mathematics learning achievement than those treated with PBL and conventional model; those treated with PBL had the same achievement as those treated with conventional model. Viewed from their low learning creativity, students treated with RT, PBL and conventional had the same  mathematics learning achievement.Keywords: RT, PBL, learning creativity, the mathematical achievement.
