This study aims to determine the effect of the application of Problem Based Learning method on the scientific attitude and learning results of 7th grade students in MTs NW 01 Kembang Kerang towards the study materials in biology. This research is a Quasi Experiment (Pseudo-experiment) that was designed to use both Pre-test and Post-test control groups. The study samples were taken randomly from two different classes i.e. VII C as the experimental group and VII D as the control. The output of this study was presented in a scientific attitude of the students, analysed by descriptive test as well as the learning results of the students which were observed by unpaired T-test. The results showed that there was a significant difference in the scientific attitude of the students in the experimental class compared to the control one where the conventional method was applied. This was shown by the difference in the variance of students’ attitude (86.6% in the experimental group; 47.2% in the control). There was also a significant difference in the learning results of these students. The T-test was performed and it has been shown that the significance value was 0.019 < 0.05. To summarize this study, Problem Based Learning method had a significance impact in the scientific attitude and learning results of the students, this suggested that this method can be used as an alternative technique to teach biology in school.

The purpose of the present study is to investigate the effect of explicit affective strategy instruction on the speaking performance of Freshmen English majors at Faculty of Education, Suez University, Egypt. The design of the study is a pre-post quasi experimental one. The instrument is a pre/post speaking performance test (designed by the researcher). Participants were eighty Freshmen English majors, randomly divided into two groups: a control group (N=40) and an experimental one (N=40). During the experiment, the experimental group was explicitly taught some affective strategies (lowering anxiety, encouraging yourself and monitoring emotions) while the control group was taught using the traditional method. All participants were tested using the pre/post speaking performance test before and after the intervention. The difference between the post test&rsquo;s mean scores of the control and experimental groups were calculated using Independent Samples t-test and the difference in the mean scores between the pre- and post tests of speaking performance was calculated for each group separately using Paired Samples t-test. A significant difference was found between the post test&rsquo;s mean scores of the control and the experimental groups in favor of the experimental group. Moreover, a significant difference was found between the mean scores of the pre and post test of the experimental group in favor of the post test. It was concluded that participants&rsquo; level of speaking performance significantly improved after receiving the explicit affective strategy instruction.

Implementation of animation as an Arabic language teaching aid is an innovation in creating an atmosphere that can influence student achievement. This study aimed to identify the effectiveness of the use of animation in Arabic language teaching and learning among diploma students at Universiti Sultan Zainal Abidin (UniSZA), Terengganu, Malaysia. A total of 66 diploma students were randomly selected and divided into experimental group (n = 33) and control group (n = 33). The results obtained from the data collected from pre-and post-test for each group were analyzed using t-test in SPSS version 17.0. The results showed a significant difference of (t = 8789, df = 64, p <0.05) between the achievement of the experimental group and the control group in the post test. The difference in mean score of the experimental group and the control group was 33.03. This shows that there is significant improvement in Arabic language according to the groups. The difference prove that the use of animation in learning sessions contribute to the achievement of students in the Arabic language.

This quasi-experimental study involves the experimental and control group which consist of 60 students in first year of SMA Muhammadiyah Sidenreng Rappang   2019/2020 academic year.  The reading test is used to collect data to find out do the students can achieve significant result in reading test using Text-based Character. Based on the result the mean score of the experimental group pre-test was 72.67 and classified into good classification, while the control group was 69.63 classified into good. The mean score of the post-test after treatment for the experimental group was 82.43 (very good) while the control group was 76.53, (good) classification still.  The researcher found that the T-table is higher than the t-test (α) (1.659<2.021). It means that there is a significant difference in the pre-test of the control and experimental group, while in post-test of an experimental and control group, the researcher finds that the T-test is higher than the alpha and previous score in the the pre-test (α) (3.089>2.021). The degree of freedom is 58. This study reveals that the alternative hypothesis (H1) was accepted, and the null hypothesis (H0) was rejected.

It is important to optimize working memory because it transforms, synergizes and constantly updates new and old information. One way to optimize working memory is to listen to Murottal Al-Qur'an, because it has a harmonious tone which can stabilize the mind to properly process the information. This study aims to determine the effect of listening to the Al-Quran murottal on working memory. The research subjects were 24 students of Psikologi 2017, grouped equally in the control and experimental groups. An experimental intervention was administered for 15 consecutive days lasting 15 minutes and 52 seconds. Measurements in working memory use Operation Span Task, Reading Span Task and Symmetry Span Task. The design of the study used a pre-test post-test control group and the data were analyzed by t-test. The results showed a significant difference between the control group and the experimental group on the symmetry span task subtest (p = 0.044, p <0.05).

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.
