Project Activities
In previous work, the researchers completed 10 chemistry topics for this computer-based learning and assessment system. In this project, they are developing three additional modules (Kinetics, Thermochemistry, and Solution Stoichiometry) to yield a comprehensive chemistry curriculum. In addition, the researchers are conducting a study using random assignment to assess the potential efficacy of the computer-based learning and assessment system for improving student achievement in chemistry.
Structured Abstract
Setting
High schools from both urban and rural settings in several states are participating, including California, Kansas, Kentucky, Maryland, New Mexico, Ohio, Oklahoma, and Pennsylvania.
Sample
The population includes high school chemistry teachers and students. The participating schools are selected to ensure a diverse population with regard to geographic location, teacher experience, and student characteristics.
This computer-based learning and assessment system is designed to provide feedback to students while they are trying to solve chemistry problems. In addition, the system generates reports for teachers and students that analyze student learning and performance. Previously, the researchers completed 10 chemistry modules for this computer-based system. In this project, they are developing three new modules (Kinetics, Thermochemistry, and Solution Stoichiometry) to yield a comprehensive chemistry curriculum.
Research design and methods
The study uses a pre- and post-test, comparison design. Fifteen to twenty chemistry teachers will have one of their chemistry classes randomly assigned to the treatment condition and a second class to the control condition. In the treatment group, the teacher and students use the computer-based tutoring and assessment programs along with normal instruction.
Control condition
The control group receives conventional chemistry instruction, without the computer-based programs.
Key measures
The primary outcome measure is student achievement in chemistry.
Data analytic strategy
This development project is intended only to obtain evidence of the potential efficacy of the intervention; initial analyses will be at the level of the student.
Products and publications
Products include a computer-based learning and assessment system for high school chemistry and reports of the potential efficacy of this system.
