ESP-Based Worktext and Grammatical Competence of Medical Technology Students

Grammatical competence plays a vital role in effective communication, particularly among Medical Technology students who are expected to use accurate language in academic and professional contexts. This study aimed to develop and evaluate an English for Specific Purposes (ESP)-based grammar worktext designed to enhance the grammatical competence of Medical Technology students in terms of subject–verb agreement, verb tenses, and sentence structure. The study employed a one-group pretest–posttest experimental research design involving thirty (30) Medical Technology students from Calayan Educational Foundation, Inc. A validated researcher-made 30-item grammar test was administered before and after the implementation of the developed ESP-based worktext. Data were analyzed using mean, standard deviation, frequency, percentage, and paired-samples t-test. Findings revealed that students initially demonstrated low to moderate grammatical competence prior to the intervention. After using the developed worktext, the students’ grammatical competence improved to a high level across all grammar areas. The results further indicated a significant difference between the pretest and posttest scores, confirming the effectiveness of the ESP-based worktext in enhancing grammatical competence. The study emphasized the importance of contextualized and discipline-specific instructional materials in improving students’ language proficiency and communication skills in specialized academic settings.
