This research investigated the impact of using manipulatives on 56 Grade 5 students’ (27 male, 29 female; age 10-11 years) mathematics achievement. A quasi experimental, action research design was utilized in which the experimental group was taught selected topics from the Number strand using manipulatives during a 3-week intervention, while the control group’s instruction did not include the use of manipulatives. Data were collected using a pre- and post-test and analysed using descriptive statistics and a Mann-Whitney U test. This analysis revealed that there was a statistically significant difference in the post-test performance of the two groups in favour of the experimental group. The effect size (r = .3) for this data was moderate. A significant difference was also found between the boys’ and girls’ post-test mathematics scores in the experimental group, with the girls outperforming the boys. A key implication of these findings is that since manipulatives were effective in significantly improving student achievement, its use could be extended and investigated further for other grade levels and mathematical topics. Strategies could also be adopted to address the disparity in performance based on gender in the sample.

This study aimed to determine the effects of using manipulatives in teaching fractions.   Quasi- experimental method of research was used in this study. It was conducted during the first quarter of S.Y. 2019-2020 among the respondents were randomly selected. Two sections of Arayat National High School were the respondents of the study. The control group was the 7-Rosal while the 7-Sampaguita was the experimental group. Both groups were given a pretest prior to the discussion about fractions and a posttest after instruction using the traditional method (control group) and the use of manipulatives (experimental group). The results were then evaluated, analysed through SPSS, and interpreted. Mean, t-test and ANCOVA were utilized to analyze and interpret the data. This study found out that the post-test scores of the respondents from the two groups improved in comparison to their pre-test scores.  The mean pretest and mean posttest scores of both groups showed significant difference. The results showed that the use of virtual manipulatives in converting fractions to decimals had significant difference compared the use of the traditional method. On the contrary, teaching fractions on a number line did not have significant difference. Out of the four operations on fractions, three showed that the use of concrete manipulatives was highly effective. This study recommends that teachers must test the prior knowledge of their students before discussing about fractions to determine the students’ strengths and weaknesses. Although both traditional method and the manipulative approach showed improvement on the post-test results in teaching fractions, still, teachers are encouraged to use manipulatives in teaching fractions to improve students’ performance. It is important for teachers to provide their students opportunities for hands-on manipulation of objects in order to grasp the concepts of fractions more easily. Lastly, teachers must develop the use of concrete and virtual manipulatives in teaching fractions to promote active learning that can enhance students’ mathematics performance and can help them to realize that mathematics is an enjoyable subject.

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying ‘Electrochemistry’ within a course on Analytical Chemistry. The research was of a pretest–posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at the Faculty of Education at Dokuz Eylul University. The topic was taught with PBL in the experimental group and with expository teaching strategies in the control group. The ‘Chemistry achievement test (CAT)’ was applied as the pre-test and post-test in both groups. Post-test scores from the CAT demonstrated that there was a significant difference between the academic achievements of the two groups in favour of the experimental group (U= 8.500,p< 0.05). After using PBL for a period, eleven open-ended questions related to the topic were asked to both groups. The results of these questions were categorized and the scores obtained from the categories were evaluated using content analysis. The results of the scores obtained from the open-ended questions showed that the students in the experimental group were able to make statements containing fewer misconceptions and also had a better understanding of this topic when compared to the students in the control group (U= 2.500,p< 0.05). The correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the experimental and control groups was also examined. The Spearman correlation coefficients were found to be 0.907 and 0.595 for the experimental and the control group, respectively. This finding indicated that there was a positive and very high level of statistically significant correlation between the scores in the CAT post-test and the scores obtained from the open-ended questions of the students in the experimental group. Therefore this finding also supports the conclusion that the students in the experimental group were better able to understand the topic and its structure compared to the students in the control group. At the end of the application, the results of semi-structured interviews carried out showed that students in the experimental group had positive opinions regarding PBL.
