Question

for this discussion question, please select an independent variable (iv) and a dependent variable (dv) that you find intriguing and believe would benefit from experimental research. explain the iv/dv relationship and design of a one-group quasi-experimental study to test the relationship. be sure to provide a detailed description of your design. then, please reflect on the potential threats to internal validity that may impact the results of your quasi-experimental study. you must identify and discuss at least three factors that could introduce biases or confounding variables that could affect your potential findings. please feel free to draw on any previous discussion question or assignment as a foundation for the iv/dv relationship that you select.

Answer 1

This study examines the influence of VR tools on students' retention of information, with possible threats to validity including selection bias, maturation, and testing effects.

Step-by-step explanation:

An intriguing independent variable (IV) for a quasi-experimental study could be the use of virtual reality (VR) in education, while the dependent variable (DV) would be students' retention of information. In this one-group quasi-experimental design, the IV, VR educational tools, would be introduced into the classroom, and the resulting change in information retention, the DV, would be measured. Students' performance on tests before and after the VR intervention would be compared to assess the impact.

Three potential threats to internal validity that could affect results are:

• Selection bias, where the group of students who participate might not be representative of the general population.
• Maturation, where over time, students might naturally improve or alter their test-taking skills.
• Testing effect, where repeated testing may cause students to become more adept at test-taking rather than the VR tool improving their knowledge retention.

To mitigate these factors, careful consideration must be given to participant selection, the timing of tests, and the potential for alternative influences on the DV. Placebos and blinding can be difficult to implement in this context but should still be considered.
