The activities draw the user to specific observations, and ask him guided questions about it. This way it motivates users to observe and analyze the events they view while flying in the virtual system. For example, for helping the user understand moon phases, he/she is positioned above the Moon’s orbital plane to observe the Moon, the Earth and the sun, and asked to pay attention to the changes of the angle between the Moon’s illuminated part and the Earth. By doing the activities users get more intuitive understanding of astronomy and develop essential visual literacy and information processing skills. (Yair, Mintz & Litvak, 2001)
The Rationale Behind the Feature (Specific Design Principle):
The Virtual Solar System is a non-immersive 3D virtual environment. It contains the sun, planets, moons, asteroids and comets, revolving and rotating on the background of the Milky Way, the stars and constellations. The user flies in the solar system by the computer mouse as a spaceship.
The virtual solar system is full of information and the learner has to control this flow of information. The rational behind adding the set of structured inquiries to the learning environment, is to focus the user on specific aspects of astronomy. (Gazit & Chen, 2003; Gazit, Chen & Yair, under review; Yair, Mintz & Litvak, 2001)
Context of Use:
A case-study research was conducted with ten 10th grade volunteered students, in order to study their learning process during a real-time interaction with the VSS, and to analyze the development of their understanding of basic astronomical phenomena and of possible alternative concepts. Some of the students participated in this study developed alternative misconceptions during the interaction. The researchers assume, that the emergence of alternative concepts may be reduced or prevented by instruction and appropriate activities and scaffolds. The VSS contains structured inquiries that focus the user on specific aspects and ask him guided questions. (Gazit, Yair & Chen, under review)
