The author has undergone a major shift in the way of teaching his undergraduate computer programming courses. In the classroom, the teacher's computer is connected to a splitter and a video projector that display the computer's screen to the entire class. Using this technology, the programming language itself is used live in class to help the students learn how to program. The students are learning in a context by far livelier than those of previous methods. Teaching computer programming is not achieved by lecturing and writing the program instructions on board or by displaying program instructions to the class on transparencies or slides of electronic presentations. With the implementation of student-centered approaches, the students migrated from the state of passive receivers to constructors of computer programming concepts. Students are coached to develop a sense of exploration, individuality and autonomous thinking. The enthusiasm for technology has been facilitating and supporting the learner-centered approach. Everyone in this approach is a learner, including the teacher.
