Evaluating the Effectiveness of Semantic Mapping in Learning Specialized Academic English (EAP).

Abstract

One of the major challenges students face when learning to use specialized vocabulary in English for Academic Purposes (EAP) is the challenge of learning new vocabulary. This is particularly true when, as is so often the case, more traditional methods of learning vocabulary such as memorization are used instead of strategies that promote a deeper understanding of vocabulary and better retention over time. Semantic mapping provides one possible solution to this problem, by enabling students to make meaningful connections between new vocabulary and what they already know. This study investigates the effectiveness of semantic mapping as a tool in teaching specialized academic English, focusing on its contribution to the students’ learning of new vocabulary, their comprehension of reading materials, and their level of engagement. This study used a mixed-methods approach to test the effectiveness of a vocabulary instructional strategy over an 8-week time frame. Measuring vocabulary retention and reading comprehension, two tests were administered to the experimental group (using semantic mapping for vocabulary) and the control group (relying on traditional methods for teaching vocabulary). A 10-item questionnaire was given to the experimental group in order to qualitatively obtain the students’ perspectives, views, and feelings as well as their particular challenges with semantic mapping for learning new vocabulary. Quantitative analysis indicated that the experimental group achieved significantly higher post-test scores in both specialized vocabulary retention and academic text comprehension compared to the control group. Qualitative insights revealed that semantic mapping enhanced conceptual clarity, boosted learning motivation, and facilitated a deeper understanding of word relationships, though some students initially noted challenges regarding the time required to construct the maps. The results show that semantic mapping is a highly effective pedagogical tool for students of specialized academic English. It enables students to move from passive repetition of words to active visual schematization which is useful for EAP (English for Academic Purposes) curricula and for teaching vocabulary.
