Educational psychologists investigate the impact of different types of instruction on learning. In one study, researchers taught a math lesson to 9th-graders using the "Inventing to Prepare for Learning (IPL)" instructional cycle. A second group of students received traditional "tell and practice" instruction. After the lessons, both groups studied a worked example of a math problem on their own. Then they took a test that included problems like the worked example. The journal Cognition and Instruction published the results in 2004. Pick the best description of this study:

Answer:

An observational study of an association between two variables.

Explanation:

  • In a given scenario, this is an observational study of the relationship between the two variables.
  1. Descriptive variables (independent variables / predictive variables) can explain or affect changes in the response variable.
  2. The response variable (dependent variable) measures the outcome of a study.
  • The observational study observes individuals and records variables, but does not attempt to influence response (not treatment). This allows the researcher to directly observe the behavior of perfection rather than rely on the subject's self-description, allowing the researcher to study the subject in its natural environment, thereby demonstrating the performance of the subject. But avoids the effects of unnatural laboratory settings. .
