Misconceptions
and alternative conceptions of the concept of plant cells are problems that always
occur in students. Misconception is a mistake in understanding a concept, while
an alternative conception is an understanding of an inappropriate concept. This
case is experienced by many students caused by many factors. One of the
contributing factors is the error in obtaining information about the concepts
learned. Therefore, it is necessary to
find the right learning strategy to solve these problems. This study aims to
answer the question whether learning through constructivism-based modules is effective
in reconstructing the concept of plant cells and improving learning outcomes. The
method used in this study is Experimental one group pre-test post-test design.
The research subjects were 80 students in one of the senior high schools in
Aceh Besar District, Aceh, Indonesia. Research time for three months from
February-April 2018. The parameters measured are the ability to reconstruct
concepts and increase learning outcomes. Reconstruction of concepts that
measure three aspects, namely reconstruction, understanding, and not
understanding. Improved learning outcomes are measured by calculating the
normalization of gain (n-gain). The instrument used is a constructivism-based
module and an objective test with the CRI answer sheet. Data collection was conducted
through pretest and post-test. Data analysis for concept reconstruction ability
was carried out by percentage, while to compare improvements in learning
outcomes were tested by two different test means using one sample t-test. The
results showed that the ability to understand the concept increased 54.56%, did
not understand 44.44% decreased, and misconceptions decreased 10.33%. The
t-test results also show that there is a significant difference between pretest
scores (initial ability) and n-gain score (final ability) at a significant
level of 95% (α = 0.05). The conclusion of this study is that learning through
constructivism-based modules is effective in improving cell concept
reconstruction capabilities and improving student learning outcomes.
