The study investigates the effect of mind-mapping strategy as a self-regulated learning strategy on students' on achievement in Basic Science and Technology(BST)

This paper addresses the effect of The TTMC diagnostic assessment Model in basic science technology and to see if it can make an important contribution to the student learning outcome in basic science and technology among Nigerian students at the junior secondary school (JSS) level. The paper addresses the importance of the diagnostic assessment in basic science and technology and a review of development in particular the TTMC diagnostic instrument and sees if it can make any contribution to students' learning outcome among Nigerian students at the Junior Secondary School (JSS) level. The study is a quasi-experimenter research designed to determine the effect of TTMC diagnostic instruction on students' performance in BST. It is quasi experiment study in which the effect of the treatment on interest, attitude and achievement was measure as students' learning outcome. The sample of the study consisted of 108 JSS basic science students selected randomly from 3 junior secondary schools in Ondo state Nigeria. Among these students were 54 male and 54 females selected through stratified random sampling technique. The instrument for dada collection in the study were BST Two-tiers multiple choice TTMC achievement test of 20 items adopted from Tan and Trannguest 1990; Tin 2004Wang 2004 and from Chin and Ho 2002; The test was administered to the subject as pre-test; before the treatment and as post-test immediately after the treatment and the retention test after 4 weeks of the post-test except for the control group which was not expose to any treatment. The scores were analysed using mean; standard deviation; analysis of variance ANOVA; ANCOVA and the multiple classification analysis.

The study measures and predicts the effect of attitude and interest of students on academic performance in science. It investigates which of the variables, as essential attribute to study integrated science, will predict students' performance. Its aim is also to find out which one of the variables is influenced first under a particular teaching method. Three instruments were used for the study. They are, Science Oriented Attitude Scale (SOAS), Science Vocational Interest Inventory (SVII) and Achievement Test in Integrated Science (ATIS). The study is a quasi-experimental type. The sample of the study consisted of 30 Junior Secondary School one Students in Nigeria. Multiple regression was used to analyze the hypothesis raised for the study and the outcome shows that Science Interest possessed the strongest strength for predicting performance than attitude among the students in their different ability level group. It is therefore recommended that, teachers should use good innovative methods that will stimulate students' interest in an attempt to make learning of science more meaningful to the learners and thereby generating improved leaning outcomes that will lead to a change of attitude to science.
