A didactic sequence is proposed for the teaching of chemical equilibrium law. In this approach, we have avoided the kinetic derivation and the thermodynamic justification of the equilibrium constant. The equilibrium constant expression is established empirically by a trial-and-error approach. Additionally, students learn to use the criterion of…

This paper describes the methodology and implementation of a case study introducing the scientific literature and creative experiment design to honors general chemistry laboratory students. The purpose of this study is to determine whether first-year chemistry students can develop information literacy skills while they engage with the primary…

This paper describes how the Web-based Inquiry for Learning Science (WBI) instrument was used with preservice elementary and secondary science teachers in science methods courses to enhance their understanding of Web-based scientific inquiry. The WBI instrument is designed to help teachers identify Web-based inquiry activities for learning science…

We have designed model-development sequences using a common context to provide authentic problem-solving experiences for first-year students. The model-development sequence takes a model-eliciting activity a step further by engaging students in the exploration and adaptation of a mathematical model (e.g., procedure, algorithm, method) for solving…
