The objective of this research was to investigate the effect of a context-based approach (CBA) ‘Relating, Experiencing, Applying, Cooperating, Transferring’ (REACT) strategy used in relation to the topic of solubility equilibrium in the laboratory chemistry course on students’ achievement at associate level in a health-related program. In this regard, two contexts related to the topic of solubility equilibrium were developed and applied. The study had pre-test post-test with a control group research design and the participants consisted of sophomore students studying in the Medical Laboratory Techniques (MLT) and the Pharmacy Services (PS) Programs of the Ahmet Erdogan Vocational School of Health Services at Bulent Ecevit University (N= 96). The students enrolled in the MLT program were randomly assigned as the experimental group (n= 47) and the students in the PS program were randomly assigned as the control group (n= 49). The experimental group was taught solubility equilibrium by a CBA REACT strategy, whereas the control group was taught the relevant topic by conventional teaching. The ‘Equilibrium of Solubility Achievement Test (ESAT)’ and ‘Structured Interview Form’ were used as data collection tools in the research. The results of content analysis of ESAT post-test showed that the frequency of answers in the sound understanding category was higher for the experimental group compared to the control group students. In addition, the results of Mann–WhitneyUand Wilcoxon tests of the ESAT indicated that post-test scores were higher in both groups compared to pre-test scores and the increase was higher in the experimental group compared to the control group. The content analysis results of structured interview form and semi-structured interviews showed that the students expressed positive views concerning the instruction and the qualities of the contexts in general. In this research, it was concluded that the CBA REACT strategy used in relation to the topic of solubility equilibrium in the laboratory chemistry course improved students’ sound understanding and achievement and helped them develop positive views regarding the instruction and the quality of the contexts.

This study attempted to show that a change in ethnocentrism could be accomplished through the use of behavior modification techniques. A total of 18 Caucasian subjects were divided into six groups: three control groups and three experimental groups. In one control and one experimental condition, Ss read statements printed on index cards. Experimental group Ss were reinforced for reading certain anti-ethnocentric statements. Control group Ss received no reinforcement no matter what statements they made. In a second condition, Ss underwent a structured interview with experimental Ss being reinforced for anti-ethnocentric statements. Attitude change was determined by subtracting the pretest from the post-test scores on the Ethnocentrism Scale which was administered to all subjects. Results showed that reinforcement was effective in producing attitude change.

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.

<p class="2M-body">Framed in metacognition and sociocultural theory, the present study aims at probing the effect of metacognitive instruction on the learners’ perceptions about listening in one hand, and examining whether this pedagogical sequence of teaching listening may lead to the learners’ listening development in the course of one semester on the other. To gather desirable data, 90 (50 males and 40 females) young Iranian EFL (English as a foreign language) learners, who were studying English in a private language institute, were the potential participants of the study. Data was gathered through semi-structured interview, open-ended questionnaire, as well as KET (Key English Test) listening test. Findings highlighted the occurrence of changes in the learners’ beliefs about listening at the end of the term after they received metacognitive listening instruction. Similarly, quantitative data analysis of the pre-and post-test indicated that the participants in the experimental group outperformed those of the control group. Results revealed that metacognitive listening instruction seems to be more beneficial for less-skilled (novice) listeners to take advantage of a process-based listening instruction to improve their listening abilities.</p>
