Abstract
This study investigated the effects of multimedia and advanced organizers on upper Basic
science students‟ performance and motivation in chemical concepts, Zaria metropolis, Kaduna
State, Nigeria. The population comprised 7,302 JSSII students. Sampled of 263 students from 3
public coeducational junior secondary schools were purposely selected from the 9 Junior
secondary schools in Zaria metropolis. The study adopted the pretest, post test non-
randomization quasi experimental and control group design. The students in experimental group
I were taught Chemical concept using multimedia (video); experimental group II were taught
chemical concept with advanced organizers (graphic), while those in control group were taught
the same concept using lecture method for the period of 5 weeks. The instruments used for data
collection were BSPT and BSMQ with reliability coefficient of 0.74 and 0.89 respectively. Eight
research questions and eight null hypotheses were formulated and tested using independent t-test,
Mann-Whitney (U-test), ANCOVA and Kruskal- wallis at 0.05 level of significance. The major
findings from the study include: Significant difference exist between the mean academic
performance of male and female students taught chemical concept with multimedia, advanced
organizer and lecture method; Significant difference exist between the motivation level of male
and female students taught chemical concept using multimedia, advanced organizers and lecture
method. Based on the findings it was recommended that multimedia and advanced organizers
should be used by Basic science teachers to teach Basic science in Junior Secondary Schools for
effective teaching and learning.
