The chemistry LearnLab consists of two main sets of course materials:

  1. An online course in stoichiometry
  2. A set of online homework that can be used in a variety of course settings.

These materials will combine virtual lab experiments with pseudotutors and other forms of support for problem solving. The materials development effort will focus on completing the materials and instrumenting all activities for data collection. The initial audience for the online course is students at Carnegie Mellon, who will take the course either the summer before arriving on campus or as a mastery portion of Modern Chemistry I. The longer-term target audience for the online course is community college students. The online homework activities are already in use in Modern Chemistry II at Carnegie Mellon and at a number of sites worldwide. (David Yaron)

Course Materials

The chemistry LearnLab consists of two main sets of course materials:

  1. An online course (currently stoichiometry, thermodynamics under development)
    • Developed as a bridge course for refreshing incoming students who were taking chemistry in the fall.
    • Contains videos, interactive flash tutors, activities with fall back scaffolding, and Virtual Labs
    • Covers concepts from the mole to reaction stoichiometry and solutions to mixed oxide problems. A complete list of concepts and procedures covered in the course is also available at http://www.chemcollective.org/ stoich/ stoich_matrix.pdf.
    • For more additional information, and to access this course, please see: http://www.chemcollective.org
  2. A set of online homework that can be used in a variety of course settings.
    • Over 75 virtual lab and scenario based problems have been written to be used in introductory college chemistry courses.
    • Concepts covered include: molarity, stoichiometry, quantitative analysis, thermochemistry, chemical equilibrium, acids and bases, solubility
    • Any virtual lab activity can produce a detailed trace of student interactions with the lab.
    • Some of these materials combine virtual lab experiments with pseudotutors and other forms of support for problem solving. The development team will work with you to add such systems to any activity you would like to use in a study.

How to get involved

You can build a study around existing material. For instance, a portion of the online stoichiometry course was modified in collaboration with the development team to create a study that compared personalized and impersonalized versions of the course videos. For more information, please see the current study below.

The materials development effort is driven by the needs of both instructors and learning scientists. Please contact the development team if you have requests for materials development.

Studies

Because these materials are online and accessible from any location, it is possible to run the same study in a large number of classroom environments.
