Some concerns have arisen regarding my paper, “An Activity Model for Scientific Inquiry,’’ in which I present a way to use the Activity Model (Harwood 2004). The initial model on which my paper was based is called the Inquiry Wheel model (Harwood, Reiff, and Phillipson 2002; Reiff, Harwood, and Phillipson 2002). The development of the Inquiry Wheel model was the subject of Reiff’s dissertation, accomplished as a collaborative work of the team (Reiff 2004). Based on my research design, we collaborated on data gathering and analysis. Reiff provided the first image of the wheel and we all worked to improve upon this until the Inquiry Wheel model was born. Phillipson and Reiff both contributed significantly to the development of the Inquiry Wheel model and their work is most appreciated.
As a team, we all contributed to the development of the Inquiry Wheel model. I encourage readers to examine Reiff’s dissertation, completed in May 2004, for the details of how this model was developed and I request that this letter be published in your journal as an erratum to the above-referenced article.
