This study aims to investigate an intervention in the application of the Butterfly Method Algorithm with the Bar Model Concept on the addition and subtractions of Fractions to Year 9 students in one of the Government secondary schools in Brunei Darussalam. The Butterfly Method is an alternative visual method for teaching fractions where the diagonal and horizontal multiplication of the denominators and numerators are employed by drawing the Butterfly. A mixed-method approach was used to explore the impact of the intervention with data gathered from the students’ written pre- and post-tests and interview transcripts. The tests conducted before and after the intervention were used to analyze students’ errors and misconceptions. The students’ written analyses of the post-test results revealed that not all of the students applied the Butterfly Method. A few students were selected for interviews in order to gain deeper insights into how they developed the errors and misconceptions from both tests. Findings from the students’ interview transcripts revealed they were not confident with the Butterfly Method, and they needed more time to be familiar with the concept. Another factor for not applying the Butterfly Method is due to students’ confusion on subtracting fractions that has the same denominators as well as subtracting a proper fraction from a whole number. This study concluded that students who applied the Butterfly Method helped them to remember the new method from the intervention satisfactorily in comparison to those who lack the confidence in applying it.

The article examines the impact of regulatory changes in the tax on dividends on the payout policy of Indian companies. The tax law was recently amended to levy tax on dividends received by large shareholders. As the promoters group is the largest shareholder, this is expected to have a negative impact on the payout policy of companies. Furthermore, companies with larger promoter holdings have a higher motivation to reduce their payout. The study covers 370 companies present in the BSE 500 Index and compares the dividend payout of the companies before and after the introduction of tax levy. The study finds that the newly introduced tax indeed caused a shift in the dividend policy of companies, particularly those companies which have high levels of inside ownership. The findings have significant implications for companies, investors and the government.

Abstract Introduction: The presented paper deals with the issues of the work of class teachers and their further education in the field of personal and social training. The main goal of the research was to find out about changes in personal and social development after the realization of social-pedagogical training. Methods: On the level of personal development, the authors were interested in the field of values and attitudes. On the level of social development, they focused on the changes in communication and opinion scales. The changes in the above fields were measured by means of a pre-test and a post-test which were administered before and after the realization of the training. Results: In the participants of the realized research, the research team, to a certain extent, succeeded in reducing prejudice and beliefs and the participants learnt about the necessity of considering students’ individual abilities and specific environmental influences on their behavior and manifestations at school. On the level of opinions, there was a shift towards a stronger belief in the significance of the impact of the environment and the family background on students’ behaviour and their personality traits. Discussion: The presented data are the results of a pilot probe and have brought initial insights related to the presented issues for the purposes of a longer and deeper research, which is in the phase of its realization. Limitations: As the project was realized with ten groups of teachers showing a deep interest in participating in it, it is not our ambition to generalize the obtained results; nevertheless, we find them interesting and inspiring. Conclusions: Along with knowledge from pedagogy and psychology, class teachers need a huge amount of creativity, ideas, techniques and methods, which can promote the development of students’ value orientation. The authors can see a clear perspective for teachers’ lifelong learning here

Introduction: Academic examinations are a very stressful event for an Bachelor of Medicine and Bachelor of Surgery (MBBS) student. While many students learn to deal with it through the use of helpful or unhelpful coping skills, many still end up with considerable psychological morbidity in the form of anxiety and depression along with deterioration in overall health. Jacobson’s Progressive Muscle Relaxation (JPMR) causes deep muscle relaxation. Aim: To find out the prevalence of stress and exam anxiety in students of 1st year MBBS and to study the impact of JPMR. Materials and Methods: It was a quasi-experimental, pretest and post-test interventional study conducted amongst the first year MBBS students studying at the Government Medical College Surat, Gujarat, India, during March to May 2019. Two months before their internal exams, 114 1st year MBBS students were recruited for the study. They were given a pretest proforma which comprised of socio-demographic profile, Perceived Stress Scale (PSS), Test Anxiety Scale (TAS) and General Health Questionnaire (GHQ) 28. They were asked to attend JPMR sessions over the following month in batches of 30 each and asked to practise JPMR for one month leading up to their exams. Total 43 students attended these sessions while 71 did not. After one month, all 114 students were again given a post-test proforma comprising of the same scales. Paired t-test was applied to compare the pretest and post-test scores to see the impact of JPMR. Results: The mean age of participants was 19 years.The students who completed their schooling in Gujarati medium and those who reported to be staying at hostel experienced significantly more TAS scores at baseline evaluation as compared to their counterparts from English medium schools and those staying at home respectively. There was a statistically significant reduction in mean scores of PSS and TAS before and after practice of JPMR in the 43 students who attended and practiced JPMR (p-value=0.005 and p-value=0.002, respectively; p-value <0.05 was considered to be significant). Conclusion: One month practice of JPMR was found to be effective in reduction of stress and exam anxiety.

This paper discusses the insightful and illuminating findings of teaching critical reading within the theoretical framework of critical pedagogy. More specifically, this paper examines the impact of a critical-reading course on students’ reading skills and beliefs about discourse production and interpretation. The course was conducted according to the principles of transformative participatory action research and, thus, a corpus of 50 essays, written by a convenience sample of 25 post-graduate students in the pre-test and post-test phases, was analyzed to examine the effect of the course on students’ reading-habits and their representations of different discourses. Pretest findings showed that most students used to think that discourses are innocent and ideology-free and that reading a text consists in understanding its general idea, extracting its writer’s viewpoint, making sense of its vocabulary, and paraphrasing it. As far as text’s function is concerned, most students used to believe that a text’s basic function is delivering information. In addition, most of them were unaware of the fact that a text has ideological and socio-political functions. Post-test findings revealed that students’ discourse awareness and reading habits have become more critical and developed at two levels: the worldview level and the meta-language level. The t-test statistics suggest that there is a significant difference of p˂.001 between students’ reading scores before and after the intervention. Therefore, the null hypothesis which says that there is no significant difference between studying critical reading from a critical pedagogy perspective and studying it from a functional or conventional perspective is false.
