In this project, digital data collection and analysis methods were implemented to determine their effects on student understanding of chemistry concepts, data analysis and conclusion making skills, and motivation. Teacher attitude and motivation were also determined. The students included in the project were from a 10th grade chemistry class, which included 25 students. Students completed a non-treatment unit in which data collection and analysis were completed without the use of technology. Digital data collection and analysis were then added to experiments and class activities during two treatment units. The digital data collection and analysis tools included data collection interfaces and probes, graphing software and simulations. The non-treatment unit and treatment units were then compared to determine the effectiveness of the intervention. Students understanding of chemistry concepts, data analysis and conclusion making, and motivation increased slightly after the treatment units. Teacher attitude and motivation also showed an increase. This project showed that the use of digital data collection and analysis has positive effects on both the students and the teacher.
