The Arabic language is one of the subjects taught in Islamic schools, and there are many lessons, including the study of linguistic grammar. One of the grammar rules taught in the SMPIT MQ is the grammar of the verb. Many students do not understand it well, especially the rule of transitive and intransitive verbs, and some of them feel bored and confused while learning these rules. Therefore, the teacher needs attractive teaching methods in his teaching to obtain the achievement of the desired purposes. The researcher used the TAI method in teaching this subject because in this way the students in the heterogeneous group will learn and help each other. This research aims to know how to conduct the teaching process using the TAI method, and to know its effects in improving students’ understanding of the subject of transitive and intransitive verbs, and to know its effects on their learning motivations. This research is classroom action research. The population for this research is second-grade students from the SMPIT MQ, who are forty students, and the sample is students from second grade A, who are 23 students. In collecting data, she conducted personal interviews, direct observation, and pre-and post-tests. The results of this research show that using the TAI method encourages students to learn intransitive and transitive verbs and increases their ability to understand them, and this method is exciting. We see this phenomenon from the students’ results: in the first round, the average grade was 4.4, in the second round it was 8.8, and in the third round, the average grade was 10.
