What? Socratic-dialogue driven, highly-structured collaborative learning activities for use in introductory Astronomy lecture courses. Designed to elicit students' misconceptions, confront their naive, incomplete, or inaccurate ideas, resolve contradictions, and demonstrate the power of conceptual models.

Activity outline

Students work through a lecture-tutorial worksheet in lecture after an interactive lecture on the topic covered in the lecture-tutorial. Each lecture-tutorial takes 10-20 minutes. While working on the lecture-tutorial, students should:

  • Work with a partner.
  • Read the instructions and the questions carefully.
  • Discuss the concepts and your answers with each other.
  • Come to a consensus on your answer before your group moves on to the next question.
  • If you are stuck or not sure of your answer, check with a nearby group.
  • If you are really stuck or don’t understand what the tutorial is asking, raise your hand and ask for help.

RESEARCH VALIDATION
Bronze Validation
This is the third highest level of research validation, corresponding to:
  • at least 1 of the "based on" categories
  • at least 1 of the "demonstrated to improve" categories
  • at least 1 of the "studied using" categories
(Categories shown below)

Research Validation Summary

Based on Research Into:

  • theories of how students learn
  • student ideas about specific topics

Demonstrated to Improve:

  • conceptual understanding
  • problem-solving skills
  • lab skills
  • beliefs and attitudes
  • attendance
  • retention of students
  • success of underrepresented groups
  • performance in subsequent classes

Studied using:

  • cycle of research and redevelopment
  • student interviews
  • classroom observations
  • analysis of written work
  • research at multiple institutions
  • research by multiple groups
  • peer-reviewed publication
