The purpose
of the study was on the chemistry of mineral ore deposits and its application
in the teaching of group cations and Anions in experimental chemistry. A total
of 120 NCE 1 chemistry students were involved in the study, this number was
made up of 73 males and 47 female drawn from two Colleges of Education in Cross
River State of Nigeria. 3 research hypotheses and Four (4) research questions
were formulated to guide the study. The instruments used in gathering data for
the study were Achievement Test in Chemistry (ATC), Chemistry Retention Test
and Cognitive Ability Test (CAT). A non-randomized pre-test – post-test control
group design was adopted for the study, Kuder-Richardson formula21 was used to
establish the reliability of Achievement Test in Chemistry (ATC) and the
reliability Coefficient of ATC was 0.83. Data collected were analysed using
Analysis of Covariance (ANCOVA) and Scheffe posthoc analysis was used to obtain
the direction of significance. From the findings, it was observed that resource
materials from the environment were effective in enhancing academic performance
scores of chemistry student with high, average and low cognitive ability levels
taught using mineral ores and standard materials. Conclusions from the findings
led to the recommendation that chemistry lecturers should explore the use of
local resource materials within their immediate environment to teach various concepts
in science and indeed chemistry.
