Anaerobic physical exercise does not only improve body fitness, but it also increases cognitive functions. The increase of cognitive functions is mediated by the increase of <em>Brain Derived Neurothropic Factor</em> (BDNF) level. Several studies revealed that anaerobic physical exercise can increase the BDNF level inhippocampal tissues. However, it is still questionable whether or notthe frequency of exercise influences the production of BDNF inhippocampal tissues. This study was to find out the BDNF mean level inhippocampal tissue of Wistarrats which were treated with anaerobic physical exercisesconducted in different frequencies.This study used <em>post test only control groupdesign. </em>The research subject was 28 rats of<em>Rattusnorvegicus strain wistar</em>divided into 4 groups; 1 control group and 3 treatment groups (one-time, three-time, and five times a week treatment). The anaerobic physical exercise used <em>animal treadmill</em>running in the speed of 35m/min for 20 minutes at four-minute intervals. The mean levels of BDNF were increased in all treatment groups compared with control group (151.588 vs 57.059). The highest mean level of hippocampal tissue BDNF was found in the treatment group of three times a week (177.701). There was a significant difference in BDNF mean levels of Wistar rat brain tissues among the treatment groups.<p> </p>

Pictures use in an educational setting fits the idiom: old but gold. There have been plenty of studies revealing how good the use of pictures in the classrooms is. Pictures have been long known to have the ability to help motivate, demonstrate, and instruct the students during a learning process. This study is a sort of complement to the phenomenon as it focuses on researching the use of pictures in a classroom. Specifically, it aims at finding out the effectiveness of the use of picture cues in teaching writing.The study belongs to experimental research involving two groups of experiment and control. The eighth-grade students of a private junior high school in Central Java Indonesia are chosen as the subject of the research during 2017/2018 academic year. Employing a sample population technique, the study involves a total number of 56 students who are equally divided into 28 students as the experimental group and 28 students as the control group. The experimental group is taught using picture cues while the control group is taught without picture cues. Pre-test and post-test are used as techniques to collect the data. As for the data analysis technique, it’s done quantitatively applying both descriptive and inferential statistics.The result of the research shows that there is a significant difference in the students’ writing ability between those taught using picture cues and those who are not. This can be seen from the difference in the mean score between them. The result of the pre-test shows that at the beginning, both experimental and control groups have slightly different ability in writing with the mean scores 51.32 and 47.86 respectively. Meanwhile, the result of the post-test indicates an obvious difference between them in which the experimental group gains 65.75 as its mean score and the control group gets 59.14. Furthermore, the application of Independent t-test calculation results in a score of 0.000, which is lower than 0.05. This means that the use of picture cues is effective. Based on these results, it can be concluded that the use of picture cues is effective to teach writing to students.

Objective The present study was conducted with the objective of investigating the effectiveness of solution-focused group counseling (SFGC) on promoting the mental health of midwifery students. Methods The present study is an intervention-based study with a pretest, a post-test, and a control group. The statistical population included all of the midwifery students studying in the midwifery department of the Bam University of Medical Sciences, Kerman, Iran, who filled out the General Health Questionnaire (GHQ) in the screening phase. In the second phase, 40 individuals, having a low level of mental health based on the cutoff score of 23, were selected and randomly divided into 2 groups (intervention and control), each group with 20 participants. The intervention group participated in 5 sessions of 75 minutes for SFGC. Then, the post-test was held in both groups and the data analysis was conducted using the Mann-Whitney and the Kruskal-Wallis test with IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, NY, USA). The significance level was considered as p < 0.05. Results The findings showed that the mean of the post-test mental health scores of the intervention group (14.5 ± 50.35) and of the control group (23.6 ± 35.83) showed a statistically significant difference (p < 0.0001). Moreover, the comparison between the mean scores of the mental health subscales (physical symptoms, stress, social performance, and depression) showed a statistically significant difference in these groups, and SFGC improved physical symptoms, stress, social performance, and depression in the members of the intervention group. Conclusion Solution-focused group counseling may improve all levels of mental health. This type of counseling is recommended to be used to solve the psychological problems and to improve the mental health of students, as well as of the staff of the health system.

The current study determines the effectiveness of using task-based language instructions in teaching writing at a high school in Thai Nguyen province. The participants consist of 92 grade 10 students from Bing Yen high school, Dinh Hoa district. The study employs a mix method research design (MMR) as the plan for the research. The results of the study reveals that the results of writing performance were reported at a low level (M=3.72). The results also confirmed that the intervention worked well for the experimental group. The mean score of the pre-test (the baseline for both groups) was M=3.72. The intervention focused on TBLT instructions. After first five weeks, the means of post-test1 were M=4.96 and M=3.83 for experimental group and control group respectively. There was a significant difference between the mean of pre-test and post-test1 for the experimental group (M=3.72 compared to M=4.96), while the control group showed a little improvement (M=3.72 compared to M=3.83) the difference was not significant. After another five weeks, the difference in the mean scores of the experimental group were far more than the mean scores of the control group, M=5.56 and M=4.45 respectively. By the end of the fifteenth week of the intervention, the mean of post-test 3 of the experimental group reached M=6.41, the mean for control group was M=5.54. The difference of the mean scores in the pre-test and post-test revealed a significant improvement in both groups. However, the experimental group showed a greater improvement, M=6.41 and M=5.54 respectively. It can infer that the uses of TBLT writing instruction improved writing achievement greatly.

This research was intended to investigate the effect of a culture-based approach in improving students’ reading comprehension on spoof text. For that purpose, a true experimental study was applied to the eleventh-grade students of SMAN 1 Soreang. The sample of this study was 88 students from that school. These students were divided equally into the control and experimental group. The experimental group was given the Culture-Based Approach (CBA) as the treatment in comprehending the text.  The students’ scores of pre-test and post-test from both groups were statistically analyzed and compared by the T-test. The findings could be summarized that generally, students from the experimental group gained better achievement than from the control group on their post-test scores. The data analysis also showed that there was a significant difference between the mean score of the pre-test (53.45) and the post-test (58.39.). Furthermore, the result of the t-test (5.707) was relatively higher than the t- table (2.018) for a 0.5 percent level of significance. It indicated that the students’ achievement was significantly improved after the treatment of using a Culture-Based Approach. Thus, it is recommended that a Culture-Based Approach should be considered as an alternative choice for English teachers in teaching spoof text.
