Abstract;Student Teams Achievement Divisions (STAD) has been considered as an important cooperative learning strategy in progressive pedagogy. A number of studies have supported the use of STAD in different subject areas and in different socio-cultural contexts. However, it is still an underresearched area in countries like Saudi Arabia where English is taught as a Foreign Language. This quasi-experimental study was conducted in Unaizah Community College, Saudi Arabia. Both the experimental group and the control group were tested on 2000-word vocabulary test. A vocabulary test was prepared and administered by the researchers at the beginning of the experiment as a pre-test. The experimental group was taught with Student Teams Achievement Divisions (STAD) strategy whereas the control group was taught with traditional whole-class instruction method. The treatment was carried out for two weeks. At the end of the experiment, the same vocabulary test was re-administered as a post-test. Independent samples t-test was used to analyze the data using SPSS 21. Results showed that there was a significant difference between the experimental group and the control group in favor of the experimental group (p= 0.002 < 0.05).

Students Teams Achievement Division (STAD) is a cooperative learning strategy in which learners work in heterogeneous groups to achieve a common goal. It has been widely used in teaching different subject areas under different settings. This study aimed at investigating the effects of STAD on motivation of Saudi EFL learners. Two intact groups of 1st semester students were selected. One group worked as the experimental group and the other one as the control group. A questionnaire was administered to both groups at the beginning of the semester. The experimental group was taught with STAD whereas the control group was taught with the traditional whole class teacher-fronted method. The treatment was administered for two weeks. The same questionnaire was re-administered after the treatment. The data was analyzed using independent samples t-test. Findings revealed that there was no significant difference (p = 0.36 > 0.05) between the experimental and the control groups in terms of motivation.
