Abstract: The aims of this research were to know: (1) which one of the learning models gave a better achievement among NHT model, GI model, and direct model, (2) which one had a better achievement among the students with mathematic-logic intelligence, interpersonal intelligence, and linguistic intelligence, (3) at each of the learning models, which one had a better achievement among the students with mathematic-logic intelligence, interpersonal intelligence, and linguistic intelligence, (4) on each multiple intelligence, which one of the learning models gave a better achievement among NHT model, GI model, and direct model. The research used was quasi experimental research with 3´3 factorial design. The population of this research was all eighth grade students of Junior High School at Madiun city. The sample of this research was selected by stratified cluster random sampling technique. The sample consisted of 246 students from SMPN 4 Madiun, SMPN 6 Madiun, and SMPN 11 Madiun. The instruments used to collect the data were a questionnaire of multiple intelligences and learning mathematics achievement test. The data analysis technique used was unbalanced two ways analyze of variance. The result of the research are: (1) NHT model gave better achievement than GI model and direct model; GI model gave better achievement than direct model; (2) students with mathematic-logic intelligence had better achievement than those of students with interpersonal intelligence and linguistic intelligence; students with interpersonal intelligence had the same achievement as students with linguistic intelligence, (3) at NHT model, students with mathematic-logic intelligence, interpersonal intelligence, and linguistic intelligence had the same achievement; at GI model, students with mathematic-logic intelligence had the same achievement as students with interpersonal intelligence, students with mathematic-logic intelligence had better achievement than students with linguistic intelligence, students with interpersonal intelligence had the same achievement as students with linguistic intelligence; at direct model, students with mathematic-logic intelligence had better achievement than students with interpersonal intelligence, students with mathematic-logic intelligence had better achievement than students with linguistic intelligence, students with interpersonal intelligence had the same achievement as students with linguistic intelligence, (4) at mathematic-logic intelligence, NHT model gave the same achievement as GI model, NHT model gave better achievement than direct model, GI model gave the same achievement as direct model; at interpersonal intelligence, NHT model gave the same achievement as GI model, NHT model gave better achievement than direct model, GI model gave better achievement than direct model; at linguistic intelligence, NHT model gave better achievement than GI model, NHT model gave better achievement than direct model, GI model gave the same achievement as direct model.Keywords: GI , NHT , Multiple Intelligence
