Abstract:
This action research studied on how the use of manipulative in the teaching and
learning of integers could affect students’ performances in adding and subtracting integers,
involving Year 9 students from two mixed ability classes of the same government secondary
school in Brunei. The intervention lessons used different colored counters to represent
different signs of integers, followed by the adding and removal actions of these counters to
mirror the addition and subtraction operations, with the added concept of zero-pair. Any
improvement or beneficial outcome of the prior lesson was used to adapt the initially prepared
following lesson as part of the Design Research process. The data collection consisted of pretest
and post-test. With the use of descriptive statistics and Wilcoxon Signed Ranked Test, this
study concluded that there was the significant improvement on students’ performances in the
post-test and the effect size showed that the intervention gave big impact towards students’
learning. Item analysis indicated that the intervention improved correct attempts in questions
involving both addition and subtraction, with the more significant increase in the latter. The
overall mean scores of correct attempts in the post-tests also showed that students scored
higher on the addition of integers (89.7%) compared to subtraction of integers (81.0%).
