Abstract

This study aimed to find out to what extent an intuitively developed ESP module for Science majors, taught at Sultan Qaboos University is appropriately written in terms of lexicon when compared to a core Geology textbook. The module was developed based on key topics which appeared in the Geology textbook. This study will only be evaluating vocabulary and will not be looking at other aspects of material evaluation. The digitized pages of the Module (LANC 2050) and the Essentials of Geology Textbook were loaded into the Software of WordSmith 5.0 for analysis. The results revealed low percentage word coverage in the module as compared with the limited pedagogical word list that was developed for Geology. In addition, the high density and low consistency ratios for the module as compared to the textbook indicated the compactness of the module for teaching purposes. A very low percentage of the technical words that were related to Geology was discovered in the Module (LANC 2050).
