This paper describes the development of an online tutoring program aimed at the identifying and remediating common misconceptions associated with the Earth's tilt, heating of the Earth, and the cause of the seasons. This is done through the use of three interactive microworlds i.e., simulations of the concepts being conveyed. The first microworld simulates traveling to different hemispheres on the globe. The second simulates the angle of the Sun's rays on the Earth based on the angle of the Earth's axial tilt. The final microworld simulates the orbit of the Earth around the Sun. Testing was done on a group of students from a middle school in Central Massachusetts. Using the results, we then determined whether the activity helped students in terms of the acquisition of these concepts.
