_aABSTRACT:
521 _aThis study sought to determine the effects of Computer Assisted Instruction (CAI), as applied to selected lessons in Biological Science, on the attitude and academic performance of BS Psychology students at the City College of Manila during the first semester of academic year 2008-2009.
525 _aSpecifically, it aims to answer the following questions: 1. Is there a significant difference between the academic performance of the CAI group and the Non-
530 _aCAI group based on the following:
536 _a1.1 Pretest of the CAI group and the Non-CAI group
540 _c1.2 Pretest and Posttest of the CAI group
542 _g1.3 Pretest and posttest of the Non-CAI group
550 _a1.4 Posttest of the CAI group and the Non-CAI group 2. What are the attitude of the CAI group and the Non-CAI group toward Biology? 3. Is there a significant difference between the attitude of the CAI and the Non-CAI group toward
555 _aBiology based on the following:
580 _a3.1 Pretest of the CAI group and Non-CAI group
588 _a3.2 Pretest and Posttest of the CAI group
591 _a3.3 Pretest and Posttest of the Non-CAI group
598 _a3.4 Posttest of the CAI group and the Non-CAI group The following hypothesis were formulated: 1. There is no significant difference between the academic performance of the CAI group and the
600 _bNon-CAI group based on the following:
611 _aa. Pretest of the CAI group and the Non-CAI group
648 _2b. Pretest and Posttest of the CAI group
651 _xc. Pretest and Posttest of the Non-CAI group
655 _0d. Posttest of the CAI group and the Non-CAI group
700 _i2. There is no significant difference between the attitudes of the CAI group and the Non-CAI
711 _a group toward Biology based on the following:
740 _ea. Pretest of the CAI group and the Non-CAI group
767 _tb. Pretest and Posttest of the CAI group
773 _ac. Pretest and Posttest of the Non-CAI group
775 _td. Posttest of the CAI group and the Non-CAI group
776 _sThis study was conducted at the City College of Manila, with sixty (60) BS Psychology freshman students. Two groups were formed based on their gender and IQ level. Both the CAI and Non-CAI group has 30 students each
780 _xThis study is quasi experimental. The groups were exposed to Computer Assisted Instruction for the CAI group and traditional method for the Non-CAI group. It made use of a Pretest and Posttest for Biology, prepared by the researcher and a Biology Attitude Test which was modified from a validated instrument used in the dissertation of Belecima (2995(). The statistical treatments applied were t-test for dependent and independent samples and descriptive statistics; mean and standard deviation. Likewise, Kude-Richardson Formula 20 and Item Analysis were utilized in the validation of instruments used in the study.
785 _tThe findings of the study were as follows:
787 _x1. Using t-test for independent samples, the computed value of 0.035 against the critical value of 2.00 was not significant at 0.05 level of significance . This implies that the academic performance of both CAI and Non-CAI group were similar based on the pretest results.
800 _aThe critical value 2.045 was less than the computed value of 18.087, therefore, the null hypothesis of no significance of 0.05 level of significance using 29 degree of freedom was rejected, thus proving that learning took place under the CAI method.
810 _aUsing the t-test for dependent samples, the computed value of 15.517 was higher than the critical value of 2.045 in the pretest of the CAI Group, proving that there exists significant difference between the pretest and the posttest of the Non-CAI Group.
830 _xUsing the t-test for independent samples, the computed value of 2.978, which was higher than the critical value of 2.00, in the posttest of the CAI and the Non-CAI Groups prove that there is a significant difference between the posttest results of the CAI and the Non-CAI Group:
942 _a2. Based on the results of the Biology Attitude Pretest and Posttest, the positive attitudes towards Biology common to both group are :
