This atmosphere is an interactive, realistic scene similar to actual face-to-face teacher and student instructional environment. A major problem in determining the tutorial strategy of an ITS is how to balance the executive control of the system. In other words to what extend will the teacher be allowed to control the session and where is the point the computer will not allow any external interference. The dividing line is hard to draw and very sensitive to changes in the instructional strategy. Another aspect is that even the student would like to take over the control of execution mostly by asking questions. Now we have three main elements of the system: computer, teacher and student. Who should possess what level of executive control? This is the question we would like to discuss from different points of view in the domain of teaching science courses at secondary school level.EnglishComputer aided instructionIntelligent tutoring systemsTutorial strategyArtificial intelligenceConference Paper
