A study conducted to determine the effectiveness of books one and two of "Primary English for Tanzania," currently in use in all elementary schools in that country, had two primary purposes: to provide feedback to curriculum developers and publishers for effective revision of the texts, and to increase the awareness and involvement of the college tutors and teachers who will implement the program. Specifically, the study tried to discover if (1) the content is sequenced according to the ability of the learner, (2) the books have enough exercises to enable pupils to acquire the necessary language communication skills, and (3) the books are attractive to both the learners and the teachers. The study sample included 588 third and fourth grade pupils in two elementary schools, their English language teachers, their head teachers, and a tutor from a local college of education. Data from three instruments--a pupil's achievement test, a teacher's questionnaire, and structured interviews--were analyzed to determine pupil achievement and to discover the opinions of learners and teachers. Findings indicate that in general pupils and teachers were satisfied with the content of the texts. (Appendixes contain copies of measures used in the study.) (RBW)
