PSY507 Assess Between & Within Subjects Experimental Research Designs

For your assignment, select two of the following scenarios and answer all parts of the questions as prompted.


Although colleges and universities have utilized distance learning (i.e., online classes) for many years, teaching kindergarten through 12th-grade students using an online platform is much rarer. Unfortunately, the COVID-19 (Coronavirus) pandemic of 2020 forced K-12 schools throughout the world to turn to distance learning to teach children under 18. But how effective is an online curriculum for children who are only familiar with physical classrooms? To answer this question, your local school district asks you to conduct a series of studies focusing on the new distance learning curriculum they developed to teach K-12 students. Fortunately, the school district does have a control group option available to you should you need it. That is, some classrooms can use in-person instruction as the school has adequate safety measures in place to protect these students. The school administrator who hired you has four goals (though only the first goal must be addressed in all study designs):

  • First, the school administrator must know if online students are adequately learning material appropriate for their age group (as measured by an end-of-semester exam that all students must pass).
  • Second, the administrator would like to know if the curriculum they developed works equally well across students with different computer experience (experienced versus inexperienced).
  • Third, the administrator would like to know if students are improving as they progress through the semester.
  • Fourth, the administrator would like to know if the curriculum helps male and female students equally.

The school administrator recognizes that the COVID-19 pandemic is temporary but that other pandemics might occur in the future, or K-12 schools might naturally evolve an online component. Thus, the administrator would like to know how well distance learning students perform over the next four calendar years.
