This week’s readings were concerned with the topic of discipline based education research. The articles specifically dealt with chemistry and biology. The subject of teaching physics was not covered (thankfully). The first article, by Brownell and Kloser, discussed the topic of CUREs (2015). CUREs stands for Course-based Undergraduate Research Experience. CURE’s are an approach to labs that moves away from the traditional cookbook style of lab and toward a more subject appropriate lab model focused on inquiry and the learning of lab skills as well as the scientific method. One thing that I would like to have seen in this article is an example of a CURE type lab. The reason for this is that the table on page 528 describes cookbook labs as only focusing on the conclusions and communication aspect of the lab. The labs that I have done in the past, which I would refer to as cookbook, seem more similar to a blend of the four types of CUREs listed in the table. For example, in many chemistry labs the lab began with a review of theory, then the methods were given in cookbook fashion, analysis was usually open ended (relying on the lecture for the right approach) and then conclusions would be drawn. This seems like a CURE style of lab but I can’t be sure without a more concrete example. Also, what problem is the CURE method meant to address? Labs have been taught cookbook style for decades and many scientists have been produced from this learning approach. As a student I hated cookbook style labs but is that the main motivation for reform?
The second paper, by Galloway et al., addressed this issue of affect directly (2015). The authors surveyed students to determine how they felt about the lab. The idea behind this was that learning requires emotions as well as thought and action. The main questions that this paper raised for me was: would the results of this paper be different if the student who were surveyed were chemistry majors and if the responses to the survey corresponded to student retention. Retention in this case referring to student’s staying with their chosen major. The first question came to mind because the way a student feels about an experience can often be influenced by their motivation for completing the coursework. For example, a biology major might have no interest in chemistry but is doing the lab because they are required to. In this case generating interest or positive affect might be a significantly different undertaking then it would be for someone who is actually interested in the chemistry. Second, does a lack of interest or positive affect cause students to score poorly and/or leave the major? If so, then improving positive affect would be a hugely important topic.
The third paper, by Hofstein and Lunetta, is similar to the first paper in that it deals with the issue of reforming science labs for the modern world (2003). This paper does not seek to investigate a single form of lab instruction, like CUREs, but is more of a review paper that highlights changes in the application of labs in a learning setting over the past twenty years. The focus is still on how to move away from the cookbook style of lab and toward a more authentic style. I think that this pursuit is an important one. I have taken many chemistry labs, for example, and yet I would have no idea where to start if someone asked me to synthesize anything. The reason for this is that the labs that I did focused on learning physical tasks and following directions but never taught me why I was doing the steps in the lab. As a result, I had a tool chest of chemistry techniques but no idea of where or when to apply them, just how to apply them. I hope that this new push for lab reform solves this type of shortcoming.
