Do we learn better by reading or listeningFeatured science projectScience project video


The materials required for this science fair project:

-    5 boys and 5 girls aged 15 years

-    2 sets of comprehension passages labeled A and B

-    2 sets of question papers for the above comprehension passages (labeled Paper A and Paper B)

-    A quiet examination room

-    An assistant to help coordinate the tests


1.    For this experiment, the independent variable is the reading and listening of comprehension passages. The dependent variable is the results of the tests. This is determined by marking and grading the test papers. The constants (control variables) are the difficulty of the tests, the number of questions, the time given to read the comprehension passage  and the number of times the comprehension is heard.

2.    2 sets of comprehension passages  of equal difficulty are selected and marked A and B. For each of the comprehension papers, a set of 50 objective questions are prepared and labeled paper A and paper B.

3.    Model answers are prepared to mark and grade the papers after each test.

4.    On the day of the test, the students are given the comprehension piece marked A to read for 30 minutes. After the 30 minutes,  the comprehension passages are collected back and the test paper labeled A is given to the students to answer. After 1 hour the test papers are collected back.

5.    On the next day of the test, the comprehension passage  marked B is read out to the students several times during the given  30 minutes. The test papers labeled B are given out to the students to answer. After 1 hour the test papers are collected back.

6.    All the 20 exam papers are marked and graded using the model answers and the results recorded in the table given below.
