Data Collection Strategy and/or Instrument: ===I will collect mixed data for my research. Quantitative data will be collected in the form of pre- and posttests. Qualitative data will also be collected through the use of student surveys and interviews. The interviews will be informal conversational interviews which I will tape record per Johnson and Christensen’s suggestion (p.208). The surveys will be both qualitative (with open-ended responses) and quantitative (rating scale). By utilizing three out of the six most common methods of data collection used by educational researchers (Johnson & Christensen, 2008, p.200), I hope to collect a wealth of data which will help me determine whether or not CAI had a positive effect on student achievement in math. === ===I plan to use four math classes for my research. All students would receive the same classroom instruction. Two classes would be the experimental group. Students in this group would receive additional CAI in math to reinforce concepts taught. These students would receive daily sessions (10-15 minutes each) of math CAI for eight weeks. The other two classes would be the control group for the research. These students would not receive additional CAI for math. At the end of eight weeks, both groups would take the posttest. Data would be analyzed to determine whether or not the use of the CAI had a postitive effect on student performance in math. ===
