Data Collection Instruments and the Data Collection Process
For the purpose of determining the effect of the 4MAT teaching model in the
teaching of attainments in the 8th grade algebra learning domain on the
achievement of students, the algebra test developed by Övez-Dikkartın (2012) was applied prior to and after the application as pre-test and post-test. The alpha
value obtained as a result of the item test of the test measuring thirteen
attainments in the learning domain and prepared in line with opinions of experts,
was determined to be 0.818. [9]. Prior to the data collection process, the draft of
the 4MAT curriculum that could realize the current curriculum in 5 weeks was
prepared. The prepared draft was submitted for the opinion of experts. The draft
rearranged in line with obtained opinions, was implemented at the beginning of
the term on the pilot group determined for the study with an agreement with the
lesson teacher and required arrangements were performed. The actual application
was applied by the researcher at the end of the term on the experimental group
based on the 4MAT teaching model and applied to the control group in
accordance with applications and activities in the textbook.
