Communicative Reading Comprehension Competency Influences Written Composition Skills Performance of Faculty in English Discipline

James Britton proposed three primary language functions, which researchers tested using faculty members from Tawi-Tawi Regional Agricultural College (TRAC), for communicative reading comprehension—transactional, expressive, and poetic. Tawi-Tawi has many schools with high literacy levels, which contributes to a better society and a more peaceful country. The results revealed that the gender of the respondents had no bearing on their level of communication competency, and no significant differences were found between male and female faculty members. Additionally, there was no significant relationship found between the socio-demographic profiles and teaching performance of the faculty members in the English discipline.

Influence of Family Background on Learning Outcome of Agricultural Undergraduates in Indian Conditions

Family as an entity teaches many concepts like social, economic, technical, moral concepts to the children for a better living. Thus the contribution of a family in an educational environment is undeniable. Thus this paper attempts to cull out various aspects of family background that influence the learning situation of the agricultural undergraduate students in the Indian conditions. Agricultural College and Research Institute, Coimbatore of TNAU were taken as the study center. B. Sc. (Agriculture) degree program was purposefully selected. 114 students studying final year were considered for the study by employing saturated sampling technique. Majority of the respondents’ families were found to be economically sound with stable occupation under any one sector. Being hostellers, the parents did not have adequate scope to engage in educational activities and interact with the institution. But they always find ways to back the students in all possible ways in other means.
