ABSTRACT
The study investigated the effectiveness of PQ4R study technique on performance of students in Chemistty in secondary schools in Ibadan south east Local Government Area, Oyo State. The study adopted pretest, posttest control design. A sample of 80 students selected from two schools by simple random technique was used. One school constituted the experimental group and the other the control group. An instrument which consisted of forty objective and two essay questions was developed, validated and used for the study. The instrument was titled "Chemistiy Achievement Test" (CAT.) Data collected were analyzed using t-test The results showed that while there was no difference in the pre-test scores of the experimental and control groups (t = 0.53, p > 0.05), there was a significant difference in the post-test scores(t= 8.2, p < 0.05) . The results also indicated that there was no significant difference in the performance of male and female students that used the PQ4R ( t = 0.48, p > 0.05). Hie study concluded that the PQ4R was effective in improving the performance of students in Chemistiy.

Introduction
Science students require a good performance in Chemistry to advance in their chosen careers. To excel in any science or technology based discipline demands a solid foundation in Chemistry. In the Senior School Certificate and the Unified Tertiaiy Matriculations Examinations, Chemistry is a compulsory subject for all science students. This underscores the need for a good performance in the subject. However, going by the Chemistry results in the Senior School Certificate Examination, a good number of science students do not perform well in Chemistry. In fact, it is common knowledge that the problem of poor performance in Chemistry has been on the rise. Olatunbosun (2006) corroborated this in his study. Reasons have been adduced for the persistent poor performance in Chemistry over the years. Among the reasons put forward to explain the decline in performance of students in Chemistry at the Senior School Certificate Examination are teachers' methods of teaching, lack of provision of standard infrastructure by the school management, students' negative attitude to Chemistry and lack of comprehension of written texts. No doubt, the above reasons are cogent and a pointer to the cause of students'...
