Currently, there are three possible teaching scenarios: conventional, lecture-based teaching; Web-managed teaching where lectures have been removed altogether and all learning is online; and supplemental (Web-based) teaching, which combines the previous two. This chapter describes the first phase of a project on the integration of Web-based technologies into the conventional lecture-based scenario of English grammar teaching at a large public university in Spain. It focuses on issues of planning and design of Web-based tools and materials which can potentially support the Seven Good Teaching Principles. It also describes a tentative plan to introduce the Web-based tools progressively into the lecture-based classroom so that both students and instructors become familiar with the new learning environment as the course proceeds. The author hopes that the work reported here will encourage instructors to keep abreast of innovative methods that extend the students’ learning environment beyond the traditional face-to-face meetings.
