Brief Summary
|
|
The
students will be explained the purpose of the study, and willing students will be
asked to sign the consent form.
A
particular topic in the subject of dental materials will be taught by
conventional didactic teaching and a pretest comprising of 30 multiple-choice
questions which have been item analyzed before will be administered to all the
participants. After the pretest the participating students will be divided
into two groups an interventional group and a control group comprising of all
the three types of achievers. The intervention will be administered, and a
post test will be administered for the entire participating study population.
Difference in the pre and posttest scores of the interventional and control
groups will be statistically analyzed.
A
cross over will be done for the same intervention for another topic of
comparative difficulty by switching the control group to interventional group
and vice versa.
Written
feedback will be taken from the interventional group at the end of posttest.
The
details of the interventions as follows
1.
This intervention will consist of students constructing 9 MCQ`s from the
topic taught using didactic teaching. They will be allowed the use of books
and verified internet resources. To prevent the students from copying from
entrance exam MCQ books, they will be provided with 3 single best response
questions with four options as a template from the distractors of which they
will make the MCQ`s. This will help the student constructed questions to
remain relevant to the topic. The student constructed MCQ`s will be discussed
in group which will be moderated by a faculty member.
2.
This intervention will consist of students editing distractors for 9
standardized multiple-choice questions to make them better. The same will be
followed by a group discussion with a faculty about the distractors made by
the students.
3.
The intervention will consist of students constructing match the following
item type of question. They will make one extended matching question with 9
items in one Column and 5 in the other column so that the items are unequal
in both, and each item can be used once, more than ones or not at all. They
can take help of the textbook.
4.
The intervention group will be given a match-the-following-question task to solve, which includes unequal items in both columns. They will be allowed to use the textbook for solving the question, and 10 minutes will be allocated for the
activity.
5.
The intervention group will be instructed to construct 5 multiple answer
questions, in which one, more than one or none of the options can be correct.
Each question will have 5 options. They can refer to the textbook for help.
|
6. The interventional group will be given 5
multiple-choice questions to solve at the end of the didactic session. They can
take the help of the textbook to solve the same. |
