A teacher wanted to know which learning delivery modes (pure online. pure modular, combination of online and modular) is most effective and has the fastest turnaround time
in the submission of accomplished activities among her Grade 12 students. She divided
the students into 3 groups, gave them the same activity sheets and asked them to submit
as soon as it is completed. She then compared the scores and completion time of the 3
groups
Independent variable:
Dependent variable
Extraneous variable

Independent variable:  instructional method

Dependent variable : turnaround time  in the submission of accomplished activities among her Grade 12 students

Extraneous variable: students background, students' academic ability, age of the students
