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.

Abstract The research problems of this study were (1) to find out the application of anagram technique in improving student’s vocabulary mastery and (2) to know whether there was a significant difference in vocabulary mastery between the experimental group where the anagram technique was implemented and the control group which no treatment was given during the experiment.  In this study, the writer used the quantitative method with quasi experimental group design. The samples of this study consisted of 36 students of VII E as Experimental Group and 36 students of VII F as Control Group taken from the second year students of seven classes of MTs N Pangkalpinang. The result of the test was analyzed by using statistical analysis of Paired sample t-test and Independent sample t-test. Based on the result analysis, there were two major findings, namely (1) the implementation of Anagram technique in developing students’ vocabulary mastery was successful and the result of difference analysis in post-test of experimental and control group showed that the value of t-obtained was 3.488 which was higher than t-table 2.03 (at the significant level p<0.05 in two tailed testing with degree of freedom 70). The result of this study showed when the means of the post tests between the two classes were compared, the post-test scores were better than the pre-test scores (43.31)for the experimental group (80.89).

This study employed the Multiple-draft Method in the teaching of Continuous Writing in English<br />Language. The intent was to determine if there could be significant difference in the performance of a<br />group of students taught with the conventional method of Reading-Writing (a type of controlled writing)<br />and another group taught with Multi-drafts method of writing. The study employed the pre-test and<br />post-test controls and quasi-experimental research design. The sample consisted of 80 senior secondary<br />school students. The instrument which was used to gather data which was the West African<br />Examinations Council’s (WAEC) English Language Essay Questions. The data generated were<br />subjected to statistical analysis and the results of the analysis showed that at take-off the two groups<br />were homogenous. There was significant difference in the post-test scores of the experimental<br />outweighing the control group which came about as a result of treatment of the experimental group.<br />There was no significant difference between the pre-test and post-test scores of the students in the<br />control group. As evident from the out-come of the research, the Multiple- draft method (which allows<br />students to practice with many drafts before the final writing) had significant effect on students’<br />performance in Continuous Writing. Hence, the Multiple- draft Method was recommended for<br />Continuous Writing.

Making connections between the representations of trigonometric functions and an interpretation of graphs of the functions are major challenges to many students. This study explores the effectiveness of the GeoGebra on grade 12 students’ success in making connections between the representations of trigonometric functions and the interpretation of graphs. A non-equivalent control-group pre-test post-test quasi-experimental design was used. The sample of the study consisted of sixty-one grade 12 students from two schools. The results showed that there was a statistically significant difference between the mean achievements of the experimental group and the control group on making connections between representations of trigonometric functions, and on analyses and interpretations of representations of trigonometric functions, in favour of the experimental group. This study extends the findings of previous studies on the effectiveness of dynamic mathematics software on students’ learning of representations and interpretation of graphs of trigonometric functions.            Keywords: GeoGebra, functions graphs, Trigonometric functions

Cyber bullying is the unwise use of technology to harm and humiliate an individual or group over the Internet. The purpose of this article is to test the effectiveness of the cyber bullying sensitisation program (CBSP) to reduce the level of cyber bullying behaviour among middle school students. The sample was restricted to adolescents as they are the ones who are most exposed and vulnerable in the cyber space. A quasi-experimental pre-post design with intervention was adopted for the study. The participants of the study were comprised of 186 middle school students from two private schools in India. The experimental group had 94 participants while control groups had 92 participants. Statistical analysis indicated that there was a significant difference between pre- and post-test scores in the experimental group. No significant difference was found between the experiment and control group before the program, suggesting that the program was effective in helping students in reducing cyber bullying behaviour. The implications for prevention and intervention programs were discussed.

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.

<p class="Abstract">Drawing – based modeling as learning approach, it allows students to create models based on drawing which help them to run a simulation. Students can use drawing–based modeling to learn a pair of interacting population known as predato–prey system while they usually conducted practicum using diagram of organisms. This study was to explore students’ argumentation and students’ understanding on the concept of the ecosystem. The study was conducted quasi – experimental using the matching – only post-test – only control group design. The participants consist of 60 grade 10 senior high school students in Subang, West Java. They are placed into two groups, 30 students in the experimental group and 30 students in the control group. Data was collected through argumentation test and selected response test for assessing students’ understanding. Students’ argumentation were analyzed using Toulmin’s argumentation pattern and statistical analysis. The result showed there is no significant difference between the experimental group and the control group for students’ argumentation. Most of the students are predominantly at level 2. But the coherency of arguments of the experimental group is more coherent than the control group. It means that the students in experimental group can make logical claim and supported by the correct and relevant grounds (data, warrant, and backing). The result of students’ understanding showed there is a significant mean score between the experimental group and the control group whether 72.33 for the experimental group and 62.13 for the control group</p>

This study aimed to find out if Physics Education Technology (PhET) simulations can improve the performance of the Baybay City Senior High School STEM students on the selected topic in physics, that is, electrodynamics. This study utilized a quasi-experimental type where pre-test and post-test are multiple choice type of test and involved 72 STEM students. The grouping of the students was identified based on their sections, one section served as the control group and other is the experimental group. Experimental group is allowed to play the PhET simulation for an hour utilizing their vacant period every day, while the control is not exposed to any activity that intervene leading to the creation of formal construct of ideas in electrodynamics. Result showed that mean scores of the control and experimental groups does not imply a significant difference, despite of the interest shown by the students in playing the said simulation. Perhaps, students are more attracted to simulation in which they have gone through during their lectures. Furthermore, study shows that the performance of students before and after exposure to PhET simulation does not necessarily pose a big difference but indicates a slight improvement to their performances.
