The results gained from the analysis could be directly useful for teachers or course

designers who wish to know what vocabulary is actually taught to Engineering students and
if it is worth teaching and suitable for the students. The f ndings could also aid teachers to

decide whether to retain or redesign the teaching materials

Conclusions: An analysis of vocabulary input in English for Engineering courses at

Thammasart Universtiy, Rangsit University and Rajamangala University of Technology was
carried out to investigate if English for Engineering course materials used in universities

provide the right vocabularies for their students.

The results of the study showed that English for Engineering courses used for f rst
year students at Thammasart, Rangsit, and Rajamagala University had a primary emphasis

of vocabulary input on high frequency vocabulary or general service words. Similarly, the
GSL still played the most key role in the printed course materials for Engineering students

used in the second year. Moreover, the majority of general service words occurring in the
second year material is a repetition of general service words in f rst year textbooks. Moreover,

the f rst 1,000 words frequently occurring in the GSL were mostly used in Engineering course
materials for both f rst and second year. In addition, general service words in the study

cover nearly three fourths (1,591) of the words in the GSL. It indicated that if Engineering
students are able to be exposed to words appearing in their English for Engineering

course materials, they will be able to understand over 80% of any kinds of texts. From the
f ndings, it was found that academic words were introduced to students in the f rst year

in all universities (See Table 1). In addition, some of academic words provided for second
year Engineering students have already been confronted in the f rst year course materials.

However, a number of unseen academic words were inserted in course materials used in
the second year. It can be said that Engineering students are going to encounter more

new academic words that are essential for their academic study.

This relationship between textbook used in the f rst and the second year implied that

vocabulary input in English for the f rst year Engineering students in every university was taught
as a foundation in order to provide students with basic words (general service words) and

some frequent occurring academic words that could assist students in reading academic texts.
