Abstract Biocatalysis is one of the most important industrial methods which has been increasingly attracting attention of scientists as a new and environmentally acceptable method. It is used in the preparation of chiral alcohols - important building blocks for the synthesis of fine chemicals, pharmaceuticals, agrochemicals and analogues of natural substances. In biocatalysis the use of traditional chiral agents based on heavy metals has been replaced by the use of enzymes. In many cases, the number of reaction steps has been limited, the selectivity of the desired products has been increased while the negative impact on the environment has been reduced. The principles of biocatalysis have been applied by us to design a simple chemical experiment for the students of higher secondary education. The modified assignment of a lab task consisted of bioreduction of 4-nitroacetophenone using the enzymes present in plant tissues of carrot, parsley and white radish. Within our pedagogical research, the adequacy of the chemical experiment for secondary school students was examined and the extent of understanding of the green chemistry experiment was analysed by the method of a semi-structured interview.

It was decided by the government of Pakistan to close all educational institutions on 13th March, 2020 and all citizens were strictly advised to remain at their homes to prevent the spread of COVID-19 in the country. Due to the global pandemic, it was hypothesized that it would have a negative impact on K-12 students in their annual examinations of 2020 in science, mathematics, and technology subjects. There was constant hike in the COVID-19 cases and due to lack of technological resources in Pakistan, the country has been facing very difficult time since pandemic, especially in the area of STEM education. The data was collected from three teachers at a government secondary school in Malakand District Khyber Pakhtunkhwa province in Pakistan. These teachers were specialized in mathematics, natural sciences and technology respectively. The researcher gathered insight of teachers on the possible effects of COVID-19 on the performance of students in their respective subjects by using a semi-structured interview technique. The study unveiled that if the COVID-19 epidemic persisted for a long time, it is possible that the proportion of the secondary school students in the annual examinations would be decreased due to the disturbed academic calendar of schools.

<p> </p><p>The goal of this research is to investigate schools’ policy of using a mobile phone at schools from the perspective of secondary school students in Indonesia. It happens to be a long debate involving educators in Indonesia on whether or not the use of smartphone can be allowed in schools. So far, all we hear is the perspectives of teachers and schools’ administrators regarding the ban but never from the students, even though the students are the subject of these debates. This research is conducted in order to investigate, as well as to give the opportunity for students’ to voice their opinion, point of views, and perspectives toward the issue of banning smartphone use at schools. The data of this research was collected through online survey aimed at secondary schools’ students in Gorontalo, Indonesia. There are 250 students from 5 high schools have responded to the online surveys. The result shows that even though students mostly believe that the use of smartphone should be integrated into teaching and learning process, an appropriate policy of using it at school should be designed in order to get rid of the negative impact cause by it, and to maximize the use of it as a sophisticated resource to help students learn better at school.</p>

The rate of psychoactive substance (PAS) use in the adolescent group is increasing around the world. Drug abuse has a negative impact on students’ education especially that of secondary school students. This study aimed to assess the prevalence of psychoactive substance use and knowledge of the health consequences among secondary school students in Ogun State, Nigeria. A cross-sectional study was carried out among 528 consenting students selected using random sampling method. Data obtained using a validated modified World Health Organization’s guidelines questionnaire were analyzed with SPSS 20, p-Value ≤ 0.05 was considered significant. Majority (78.8%) were within the age group 15-18 years, males were 61.4%. Alcohol (95.0%) ranked first of all the substances been consumed among the current PAS users. Age was highly significantly associated with PAS use. Average knowledge of health consequences of PAS use was 11.5%. There is need for continuous health educational intervention to boost the respondents’ knowledge about health consequences of uses of psychoactive substances. Dhaka Univ. J. Pharm.

Environmental Friendliness

The paper investigated gender difference and practice of environmental friendliness (PEF) among senior secondary school (SSS) students in Benin Metropolis, Nigeria. The sampling population comprised 480 SSS1 students from twenty-four (24) public and private schools in Benin Metropolis. The data was analyzed using percentage, independent t-test and the Ordinary Least Square (OLS). Besides the male students were found to engage in more environmental unfriendly practices than the female students. The findings from the independent t-test showed significant gender differences in four PEFs with regard to: use of waste bins, urinating around school buildings, writing and pasting posters on the walls and bush burning. The OLS results showed that gender, school administration environmental knowledge and attitude had significantly negative impact on PEF Moreover, whereas the interaction of gender on environmental knowledge has significant and positive impact on PEF, the interaction of gender with environmental attitude has significantly negative association on PEF. Therefore, the paper has implication in the redesign of the school curriculum to address students’ environment and sustainability issues as well as the introduction of affective based teaching methods to help correct the negative students’ attitude/behaviour.

Mobile augmented reality (MAR) draws attention in terms of providing a flexible learning process and environment. It is thought that learning environments can be more effective using MAR technology. The research aimed to determine the secondary school students' views on the use of MAR technology in science teaching. The research was conducted with 143 students studying in the sixth grade at two different secondary schools in Turkey. In the research, convergent parallel patterns from mixed-method patterns were used. For eight weeks, the research was carried out to cover the systems unit in our body, situated in the 6th-grade science course curriculum. During the process, the Anatomy 4D application was used in the experimental group during the procedure, and the science course curriculum was used in the control group.  In this paper, a part of the mixed research, the qualitative data collected from the experimental group's semi-structured interview form and diaries were analyzed. Descriptive analysis was used to analyze the data. As a result of the research, although the students do not have a clear idea about AR and MAR technologies at the beginning of the application, it is observed that their thoughts change over time, and MAR applications are effective on the success of the course.

The Impact

Adolescent development involves a complex interplay between genetics, biology, and social and emotional relationships within multiple contexts of home, school and the broader community. The transition from primary to secondary school, coupled with the onset of puberty, can therefore be a difficult period for young people to negotiate at a critical period of their developmental pathway. Using a social ecological perspective, this article examines the impact of the transition experience on adolescent social and emotional health, both immediately following transition to secondary school and at the end of the first year in this new school environment. This 1-year prospective study involving 1,500 Australian Grade 8 secondary school students found that 31% of students in the sample experienced a ‘difficult’ or ‘somewhat difficult’ transition to their new school. This third of the student sample were consequently more likely to experience poorer social and emotional health, including higher levels of depression and anxiety at the end of their first year of secondary school, while controlling for these variables at the time of transition. A central message from this work exemplifies the urgent need for a longitudinal intervention trial to develop best practice guidelines for activities that help ameliorate the negative impact a change in education context can create for adolescents negotiating a rapid metamorphosis from childhood to adulthood.

The Impact

Geographic mobility has long been suspected to have a negative impact on student achievement and adjustment. Urban schools, in particular, are subject to highly mobile subpopulations whose contribution to overall district performance can be a source of serious policy concerns. The purpose of this study was to assess the impact of geographic instability on student achievement among elementary, middle, and secondary school students in an urban setting. Academic achievement of four groups of mobile children were compared to achievement levels of a stable student population. The results of the analyses show a nearly uniformly negative impact of geographic mobility on student achievement; the most negative effects of geographic mobility were found at earlier grade levels. At the same time, the size of the mobile population diminished as the students grew older.
