ESP classes are usually designed for college students after they finish EGP learning. Accordingly, textbooks used use the ones. Logically, should be lexically more sophisticated than ones, because linguistic contents also important concerns teaching, and promote students’ language development in addition to their professional advancement. This research aims compare lexical complexity between am...

Despite the body of research on textbook evaluation from the discourse analysis perspective, cohesive devices have rarely been analyzed in English for Specific Purposes (ESP) textbooks. The acquisition and use of cohesive devices is inherent to naturalistic communication, including business interactions. Hence, L2 learners of business English should be exposed to these devices through cohesion-...

This study investigated the effect of role play on improving speaking ability of Iranian pre-intermediate ESP learners. To this aim, the researchers examined the students’ speaking ability in two groups: the experimental and the control groups.24 males and femaleESPlearners at pre-intermediate level were selected by taking a pre-test. Then the participants of the current study were randomlydivi...

The concept of the textbook has been changing over the last two decades since the World Wide Web was introduced. The word “textbook” has become a metaphor when new dynamic, personal, open, reusable digital learning resources have appeared. The concrete name of this concept is still missing. We can meet words like “personal textbooks”, “open textbooks”, “flexbooks”, “personal digital library”. B...

This paper proposes a problem-based digital textbook (DT) by defining an instructional model of problem-based learning (PBL) for DTs. The objective was to develop a DT that stimulates self-directed learning through the support of a wide range of student-centered learning activities to enhance the overall learning experience and effectiveness. As an application, a problem-based DT that performs ...

The enterococcal surface protein Esp, specifically linked to nosocomial Enterococcus faecium, is involved in biofilm formation. To assess the role of Esp in endocarditis, a biofilm-associated infection, an Esp-expressing E. faecium strain (E1162) or its Esp-deficient mutant (E1162Δesp) were inoculated through a catheter into the left ventricle of rats. After 24 h, less E1162Δesp than E1162 were...

This paper reports on an analysis of the change caused by an e-textbook implementation in a school in South Africa. The PSIC model, a change model from ICT enabled change in organisations, was considered because it affirms existing educational research, but also extends it by recognising the episodic nature of change. On a vertical level the model allowed the researchers to identify and disting...
