Abstract
The use of technology is continually changing within the field of chemistry and is increasingly being incorporated into teaching laboratories under the supposition that technology makes concepts more understandable. General chemistry students at South Dakota State University use computer-based laboratory technology weekly during data collection, analysis, and final submission of their laboratory reports. The purpose of this study was to assess the impact of technology on student learning. Qualitative and quantitative methods were used to analyze this impact. Surveys, observations, and interviews were used to collect data as students completed experiments during the general chemistry laboratory. Chi-square analysis determined that changes between pre- and post-survey data were statistically significant. A qualitative index ( q) was used to assess which laboratory experiments had smaller or larger changes in student knowledge. Evidence of positive and negative changes in student conceptual and technological knowledge will be coupled to the various laboratory technology used by general chemistry laboratory students, including the Chem 2000, thermocouples, and the pH electrode. Data show that students initially were focused on learning the technology and that students re-directed their focus to learning laboratory concepts as the academic year progressed. Data show that the level of engagement students were at and their use of the visuals provided by the laboratory technology affected their learning. Data show that students emphasized collecting accurate and precise data in the laboratory and associated the technology with providing them with accurate and precise data. Data also shows the relationship between the lecture and laboratory portions of the general chemistry courses has no impact on student learning. Evidence of these impacts on student learning will be presented.
