The Impact of Communicative Approach in Developing English Language Skill in Business Education

A completely new approach in language teaching and learning with innovative attributes was introduced as Communicative English in 1970. The same approach was launched in Bangladesh in the 90s with much enthusiasm.  The new approach with all the innovative and useful blessings met criticisms both from the academicians as well as the non-academicians for the lack of grammar and translation. Everyone happens to highlight the limitations of the new approach and held it responsible as a prime hindrance to language learning. The article attempts to address problems whether Communicative English is the prime solution of the problem the country is facing or the problem lies elsewhere. The study believes that the problem is not solely with the approach but with the other related auxiliaries as well.    The pedagogy, language learning and teaching strategies, teachers’ role in teaching a FL/SL and necessity of teacher training, feeble infrastructures, imperfect evaluation system etc. related to and responsible for the problem apart from the methodology of English language teaching and learning are held responsible for the failure of the approach.   In the light of the above-mentioned problems, the study proposes how the innovative and unfamiliar contents and technique can be made operative as an instructional method.  The paper also addresses a host of solutions like developing the teaching methodology, the outlook of the teachers as well as the students and their guardians towards the new approach with its innovative contents, suggestion for an eclectic method, innovative curriculum and evaluation system, etc. which are the various suggestions proposed by the author.

Comparative evaluation of physicochemical and antimicrobial properties of rubber seed oil from different regions of Bangladesh

In Bangladesh, the annual production of rubber seeds is typically left untapped although the seeds contained a high percentage of oil but underutilized without any value-added utilization. This study aims to evaluate the geographical effect on physicochemical properties, fatty acid composition and the antimicrobial activity of oil extracted from rubber seeds. Seeds were collected from three different regions of Bangladesh and the oil was extracted by the soxhlet method using n-hexane as a solvent. Results demonstrated that the geographical regions have some significant effect on the properties of rubber seed oil (RSO). The physicochemical properties of RSO varied from region to region. For example, the percent of yield, higher heating value, and flash point varied from 50.0 to 50.8 %, 31.8–33.3 kJ/g, and 237–245 °C, respectively. The chemical parameters, such as acid value, iodine value, and hydroxyl value varied from 13.3 to 18.2 mg KOH/g, 132–137 g I2/100g, and 47.7–55.8 mg KOH/g, respectively. Chromatographic analysis showed that RSO mainly contains palmitic, linoleic, linolenic, and stearic acid. Regional variations were also seen in the composition of these fatty acids. Most notably, regardless of the rubber seeds collected from various locations, RSO exhibited inhibitory activity against only gram positive bacteria. The zone of inhibition range for different tested gram positive bacteria was 2.33–11.17 mm irrespective of different RSO samples
