The effect of case based learning on 10th grade students&rsquo / academic achievement in the unit
of human reproductive system and their perceived motivation (Intrinsic Goal Orientation,
Extrinsic Goal Orientation and Task Value) was investigated in this study.
The study was conducted during 2007-2008 spring semester in a private high school in
Ankara, Turkey. A total of 80 (48 males and 32 females) tenth grade students from four
biology classes of two teachers were involved in the study. One class of each individual
teacher was assigned as control group and the other class of the same teacher was assigned
as experimental group to sustain randomization. Two of the classes assigned as
experimental group were instructed with case based learning, while two classes of the
control group were received traditionally designed biology instruction.
In the experimental group, two cases that are divided into several parts were assigned in an
interrupted manner. Students learned the human reproductive system via cases in
experimental group without any additional method. The cases include incomplete data and
students were needed to search for and discuss to answer the questions posed in the cases
and by themselves and to complete the data. When the students completed a part of the
case, next part was distributed. While dealing with the dilemma presented in cases, students
did independent study as well as group work. In the control group, instruction was based on
teacher explanations and web based notes prepared by the biology department of the high
school.
Human Reproductive System Achievement Test, Motivated Strategies for Learning
Questionnaire were administered as pre-test and post-test to the students in both groups to
measure the students&rsquo / academic achievement in the unit of human reproductive system / and
their perceived motivation / specifically, task value, intrinsic goal orientation, and extrinsic
goal orientation.
Multivariate Analysis of Variance (MANOVA) was used to investigate the effect of case based
learning on the students&rsquo / academic achievement in the unit of human reproductive system
and their perceived motivation. Results revealed that case based learning improved students&rsquo / academic achievement and task value.
