Adaptation of the assessment processes and its impact on learners: during and post-Covid19 situation in Bangladesh
(BRAC University, 2022-05) Tabassum, Rezuana; Al Amin, Md.
In our country, the long-established face-to-face assessment process shifted to an online mode due to the pandemic. However, teachers and the authority could not apply that established method during the remote assessment. To assess students’ knowledge, they started to take assignments that were assigned by the teachers. Besides assignments, teachers used continuous assessment procedures to assess learners’ knowledge. The assessment process changed again when the pandemic’s intensity started to cool off and everything was gradually returning to its place. Therefore, this study focuses on the two aspects of English assessment at the junior secondary level of Bangladesh; one is the adaptation of the assessment process of English throughout the pandemic as well as in the time of post-pandemic transition and another aspect is the impact it had on students and teachers during the same period. This study is accomplished by following a qualitative research approach. All data has been collected by interviewing participants and analysed through thematic analysis. The participants are teachers and students of junior secondary level in Bangladesh. The results are reported under the following themes; i) Adaptation of Assessment Process ii) Different types of Assessments and iii) Impact of the assessment. Moreover, this study offers a brief discussion on these themes, for instance, it talks about how teachers and learners have adapted to all new assessment processes during the pandemic and in the transition to post-pandemic. Then it focuses on the types of assessments English teachers have followed in online mode as well as after the pandemic. Lastly, this study explains the impact alternative assessments had during the pandemic and are now in the post-pandemic transition period. It also examines both the positive and negative impacts of the assessment methods applied by our institutions.

(BRAC University, 2020-10) Oishi, Alifa Reza; Al Amin, Md.
This study examines the role of the textbook English for Today in the context of teaching English in Bangladesh, specifically at the secondary school level (Class IX-X). Textbooks is one of the important elements in teaching, especially in developing countries where resources are difficult to obtain and often teachers are not trained enough to adopt suitable teaching materials. Textbooks are also considered essential for teaching in such contexts as these are systematic, easy to obtain both by teachers and students, developed and reviewed by the experts, publish nationally and aligned with the national test. However, adopting a suitable textbook, that offer ample learning opportunities and that are attractive to students and teachers, is very important. This study, qualitative in nature, critically evaluate the textbook English for Today (Class IX-X). An evaluation criteria based on the published research of Garinger, 2000 & Miekley 2005 is used to evaluate this textbook. This is supplemented by teachers’ and students’ opinion. Based on the data I provide a holistic picture of this widely used textbook. Finally I expect that this study will work as a guideline to make use of the full potential of a good textbook, which will ultimately help teachers and learners at the secondary schools in Bangladesh.

(BRAC University, 2019-04) Rahman, S. M. Sanzana; Al Amin, Md.
In present world, use of English language is prominent in every part of people’s lives, even in countries where English is not the native tongue. In a developing country like Bangladesh, people are using English in different social spheres, which in turn is increasing its role in formation of people’s identity. In this paper, the researcher has adopted a qualitative approach to collect data primarily from 10 Dhaka city dwellers to create a sociolinguistic profile to portray different usages of English language, understand people’s attitude towards the language, and examine it role on identity creation. The research has suggested that English has different functional needs in urban Bangladeshi context, and people give higher status to this language. Meanwhile, there is still a lot time needed in order to form a distinct Bangladeshi English variety in Bangladesh. The findings of this research will be beneficial to people interested to study the spread of English language in Bangladesh from the lenses of World Englishes. Finally, it can be useful for policymakers who are in charge of making language planning decisions.
An exploratory study of English teaching and learning in three Alia Madrasahs of Bangladesh
(BRAC University, 2019-08) Haque, Sazzadul; Al Amin, Md.
Over time, global, economic, social and political diagram has transformed significantly. All those components had contributed an extension and alteration in the traditional culture, which, in bi-product had resulted into a mixed cultural environment. Consequently, English, as language has become an inseparable part of any society, which intends to globalize and share culture or ideas with other group, people or country. In Bangladesh, the condition of learning skills or knowledge, be it for academic or hobbies has developed to a greater extent due to expansion of modern initiatives and digitalization. English, as a language is given high significance in case of learning and attaining proficiency both for academic and optional reasons. But the scenario is different in the Alia Madrasahs of Bangladesh. Modern methods, initiatives and expansion of scope in learning and expertizing in English language is ignored, which resulted crisis in the advancement of the students of Alia Madrasah. Moreover, though the Government of Bangladesh has formulated various general rules and regulations to improve this condition. However, due to religious, financial issues or the traditional mainstreams prevailing in the Alia Madrasahs, English language proficiency has been limited to a slower growth. Causes such as lack of understanding about the importance of learning English and its main objective i.e. communication is also responsible for this adverse situation. This study explores the contemporary picture of English language learning and teaching in the Alia Madrasahs of Bangladesh. The complications that have been observed are shortage of the administrative and technical factors which affect progressive English learning. The students’ motivation towards learning English language, failure of attaining proficiency which delays proper English learning, shortcomings of digitalization implemented for the learning process of English language in the Alia Madrasahs of Bangladesh, along with others.

(BRAC University, 2022) Shariah, Mustan; Al Amin, Md.
English is the lingua franca of the world in almost all cases. It is the language of higher education in almost all the universities of the world. Almost all the universities in Bangladesh, particularly all the private universities, use English as the medium of study. Therefore, in order to succeed in universities having good English skills is one of the prerequisites. To develop undergraduate students’ English skills universities often offer English courses known as English for Specific Purposes (ESP) courses. In Bangladeshi context, ESP courses are provided to undergraduate students to develop their English speaking and writing skills. However, the ways in which students are taught in the ESP courses – combined with the syllabus, materials, and classroom setting – should improve to achieve more effective results. This study is a qualitative study in nature, and it explores the perception of business students of some private universities regarding the effectiveness of theses courses. Data for this research was collected through online interviews due to the COVID-19 pandemic’s restrictions. Participants are current students from three universities and some have already passed from the same universities and are working in different sectors. This study has found out that there are lots of lacking regarding the syllabus and teaching method of ESP courses. Moreover, the study finds that students also should grow their interest in learning. Finally, this study has suggested some recommendations that may help the learners and teachers to get the proper use of ESP courses and benefit from them.

In this study, we designed a six stories Residential building Considering all Forces. The objective of this study to design and detailing (column, beam, slab). The basic methodology adopted here is the sequential presentation of design all force of six storied building for earthquake and wind effect by UBC1994, BNBC and ACI code 318-99 code proposed places in Bangladesh. Analysis has been performed with ETABS. A residential building with a reinforced concrete frame with six floors was applied to perform its intended purpose while also catering to the needs and comfort of the residents. To accomplish the architectural design, we used AutoCAD tools and ETABS to design and evaluate the building's structure. The structural planning and design process involve not only imagination and intellectual thinking, but also a thorough understanding of structural engineering science, as well as practical knowledge of modern design codes and bye-laws, backed up by ample experience, intuition, and judgment. The goal of standards is to ensure and improve safety while maintaining a careful balance between cost and safety. Using an excel application, the moments in slabs were calculated using method two with approximation to factors and loads in beams with moments and design portion and reinforcement. This program is more effective for analyzing the two-way slab by combining a few factors relating to slab type, beam and column dimensions, and the expected applied load. Finally, we organized the findings into architectural and structural maps for this structure.

(BRAC University, 2019-12) Kabir, S.M. Arefin; Al Amin, Md.
This study explores how a pre-university English course helps developing students’ English skills particularly speaking and listening and prepare them to cope with the English skills necessary for the higher studies at the university level. Most of the private universities in Bangladesh offer English courses for the newly admitted students which aim to improve students’ English skills particularly academic English skills necessary to cope up with the English medium education. Academics from the higher education institutions often complain that most of the newly admitted students lack English proficiency necessary to study at the undergraduate level. Both qualitative and quantitative data were collected and analyzed to understand the phenomena. This study concludes that pre-university EAP courses are necessary to prepare students for the subsequent higher study. These courses are also effective to develop students’ speaking and listening skills. This study also found that EAP courses are designed to improve four macro skills, which are Speaking, Listening, Reading and Writing. The study recommends to design EAP courses with more focus on speaking andlistening.

Exploring how teachers perceive the need for teacher education for secondary level education in Bangladesh
(BRAC University, 2022-10) Tasnim, Nishat; Al Amin, Md.
In a world where education plays a major role in the development of nations and individuals, the need for good teachers is always rising. Correspondingly, the need for good quality teacher education programs in every country is increasingly important, as teachers need specific training to master the skills of pedagogy. Bangladesh, for instance, has quite a few options for teachers’ professional development, however, there is little knowledge on teachers’ perspectives on these programs in Bangladesh, or teacher education in general. Whilst there are many studies on teacher education programs in Bangladesh, the current study sets out to explore how teachers choose to advance their career especially to teach secondary level learners. The findings indicate a variety of perspectives that sheds light on some of the realities of teacher’s professional development in Bangladesh in the secondary level education sector.
How external standardized language exams and exam prospects affect Bangladeshi students
(BRAC University, 2021-12) Janum, Jarjina; Al Amin, Md.
Bangladeshi students who aim to go abroad for higher education often have to give external standardized exams like IELTS, TOEFL, SAT, GMAT and GRE. Such an exam acts as a marker for students’ language proficiency on an international scale, as well as a gatekeeper to foreign universities. However, given Bangladesh’s non-implemented communicative framework in language learning, it is seen that the average Bangladeshi student’s English proficiency is subpar even after they complete their college education which includes about 12 years of English learning. In this paper, I have therefore focused mainly on Bangladeshi students studying under the national curriculum because they often struggle to get good scores in such tests because of the aforementioned flaws in the education system. Hence, students often have to take preparations for months on end before attending these tests. This qualitative research is done by taking extensive interviews of 10 participants through phone calls. Next, from the recorded interviews thematic analysis was done, which yielded the following themes: background and English language exposure, choice of discipline, preparation and results and challenges faced – all of which correlate to challenges and preparation of external standardized exams. Future research is recommended in this field since there is a scarcity of research on standardized language exams in Bangladesh.
If we can not do classes, we will face great loss”: the experience of university students from remote areas of Bangladesh during COVID-19
(BRAC University, 2021-05) Tasnim, Sadia; Al Amin, Md.
This research, a qualitative study in nature, has explored how effective online classes there have been for the remote tertiary students of Bangladesh amidst Covid-19 pandemic. Considering the importance of online classes at tertiary level during pandemic and its relation with remote students, it particularly emphasizes on the predicaments, experienced by them and the possibilities, they can think of attending online classes. Adopting the non-probability technique as a sampling method, data has been collected from the remote students of three public and five private universities through interviews and their perceptions are presented as a basis for discussion through thematic analysis. The results illustrate that remote students suffer in attending online classes due to financial crisis, low speed of internet, sufficient power supply, lack of suitable devices, technological knowledge, availability of service centers and adverse family environment. These factors gradually prevent them from understanding content, receiving effective feedback, teachers‟ responses and interacting with teachers. In addition to that, the convenience of time and place, technological advancements and uninterrupted education system due to online classes are documented as the possibilities, students can think of. Finally, opting for a combined education system in near future, this study concludes by suggesting some recommendations for various stakeholders to reshape and redesign online academic activities effectively during any unfavorable or unrest situation in our country.

The Bihari community of Bangladesh is a marginalized Urdu-speaking minority that faces challenges in social integration and economic opportunities. Languages are crucial for this deprived community in Geneva Camp to avail socio economic advantages. This thesis examines language's socio-economic impact on the Bihari community in Geneva Camp. It explores the implications of Urdu, Bangla, and English languages in their education, employment, and social mobility by assessing in what ways language acts as a barrier and, at the same time, how this enables access to economic resources and public services. Additionally, it seeks to find how linguistic identity, integration challenges, and generational language shifts shape their struggles and opportunities because all these are interrelated. Data was collected using a semi-structured interview to find the answers to this qualitative case study. Group discussions were conducted to collect adequate data. A purposive sampling technique was used to collect data from students, parents, and the CEO of the Council of Minorities. The findings reveal the choices of languages for economic and social survival, discrimination in Bangladeshi society, linguistic identity and integration, and generational language shift and tendency to code-switching. The findings of this research are crucial for policymakers. They provide recommendations to improve language learning policies for minority communities, thereby contributing to their social inclusion and empowerment.
NGO roles in economic empowerment of rural women in Bangladesh
(University of Dhaka, 2014-04-24) Al Amin, Md.
The ninth most populous country and the most densely populated of the world’s larger states. The position of Bangladesh is 25th among the 39th poorest countries. In Bangladesh, most of the people live in the rural areas. Mostly they are poor and cannot fulfill their basic needs. The poor people are affected in malnutrition, illiteracy, helpless and not empowered etc. There have been applied different development models through Government and Non-Government Organizations to alleviate poverty. They have great influence on the life rural woman. Their goal of development is to increase the well being and quality of life of the rural woman through growth of social vertices. Women are nearly half of the population. They represent a half of the countries human resources and thus a half of its potential. It provides micro credit to the poor woman, because they are helpless. By taking micro credit they reduce their poverty and try to change their life. It emphasizes the empowerment of rural women who are the half of the total population of Bangladesh. Empowerment can be defined as the expansion in people’s ability to make strategic life choices in a context where this ability was previously denied to them. Hence our women are very much deprived of different kinds of opportunity for the over of decades. Still it is continuing. Therefore NGO stands by them to empower in the entire life of women. In addition, there is a real change that has been done by such NGOs which are working in the study area. Women have developed and removed their sorrowful life over two decades by involving with NGO.

Eleocharis dulcis is the scientific name of a plant which are locally known as Chinese water chestnut or water chestnut or pani faul, belongs to family of Cyperaceae . The plant is indigenous to eastern Asia and China, Indonesia and Australia are grown. Usually, it is grown in the tropical, subtropical, and warming areas. This plant is grown in natively to eastern Asia and China, Indonesia and Australia . The eatable part of this plant is the underground corm, which is typically harvested. It was especially used for treating jaundice, abdominal mass, conjunctival congestion, throat swelling and pain, excrescence, bloody diarrhoea, hypertension, chronic nephritis, constipation. For anthelmintic activity, methanol fruit extract of Eleocharis dulcis was investigated for their action against Paramphistomum cervi. Different doses of each extract were examined in the bioassay, which included assurance of time of paralysis and time of death of the worms. The reference standard albendazole showed paralysis time 14.6 minutes and death time 16.8 minutes. On the other hand, methanol extract showed at dose 150 mg/ml significant effect which has paralysis time 23.0 minutes and death time 29.8 minutes. The potential of these activities may be due to the presence of most of the phytochemicals which supports previous claims and validate its uses as an expected folk medicine.

(MDPI Publications, 2023-11-07) Al Amin, Md.; Emran, Talha Bin; Khan, Jishan; Zehravi, Mehrukh; Sharma, Indu; Patil, Anasuya; Gupta, Jeetendra Kumar; Jeslin, D.; Krishnan, Karthickeyan; Das, Rajib; Nainu, Firzan; Ahmad, Irfan; Wilairatana, Polrat
Cancer is the leading cause of morbidity and mortality in people throughout the world. There are many signaling pathways associated with cancerous diseases, from which the Mitogen-activated protein kinase (MAPK) pathway performs a significant role in this regard. Apoptosis and proliferation are correlated with MAPK signaling pathways. Plenty of experimental investigations were carried out to assess the role of indole alkaloids in MAPK-mediated cancerous diseases. Previous reports established that indole alkaloids, such as vincristine and evodiamine are useful small molecules in cancer treatment via the MAPK signaling system. Indole alkaloids have the anticancer potential through different pathways. Vincristine and evodiamine are naturally occurring indole alkaloids that have strong anticancer properties. Additionally, much research is ongoing or completed with molecules belonging to this group. The current review aims to evaluate how indole alkaloids affect the MAPK signaling pathway in cancer treatment. Additionally, we focused on the advancement in the role of indole alkaloids, with the intention of modifying the MAPK signaling pathways to investigate potential new anticancer small molecules. Furthermore, clinical trials with indole alkaloids in cancer treatment are also highlighted.
