چکیده (انگلیسی):

In an attempt to impact on girls’ interest in science, an instructional package on ‘Learn Science by Doing (LSD)’
was developed to support science teachers in teaching integrated science at the junior secondary level in
Nigeria. LSD provides an instructional framework aimed at actively engaging girls in beginners’ science
through activities that are discovery-oriented and allow for experiential learning,. The goal of this study was
to show the impact of application of LSD on girls’ performance and interest in science. The m ajor hypothesis
that was tested in the study was that students would exhibit higher learning outcomes (achievement and
attitude) in science as effect of exposure to LSD instructional package. A quasi experimental design was
adopted, incorporating four all-girls schools. Three of the schools (comprising six classes) were randomly
designated as experimental and one as control. The sample comprised 357 girls (275 experimental and 82
control) and nine science teachers drawn from the experimental schools. Questi onnaire was designed to
gather data on students’ background characteristics and their attitude toward science while the cognitive
outcomes were measured using tests, Both within a group and between groups, the girls who had exposure to
LSD exhibited improved cognitive outcomes and more positive attitude towards science compared with those
who had conventional teaching. The data are consistent with previous studies indicating that interactive
learning activities increase student performance and interest.
