The main purpose of this study is to analyze effect of two different
types of Worked Example (WE) on teacher candidates’ problem solving
skills in Measurement and Evaluation course. In this study, an
experimental method with pre and post tests was used. During the
implementation process, while Text-Based WE (TB-WE, n=23) were used
in the first research group, in the second research group, Formula-Based
WE (FB-WE, n=22) were used. The content of the study includes
achievement scores, frequencies, mod, median, mean, standart deviation,
quartile deviation, ranj, T and Z standard points, p (power of item), item
discrimination index concepts and subjects. The study was completed
five weeks period. Data was collected by using a Measurement &
Evaluation Achievement Test (ME-AT) consists of items based on two-tier
multiple-choice type diagnostic instrument. To analyze quantitative data,
Wilcoxon signed rank and Mann Whitney U tests were used. Also, to
analyze qualitative data content analysis technique was use. Results
show that both the FB-WE and the TB-WE are effective approaches in
order to support teacher candidates' problem solving skills. Moreover, the
FB-WE implementation is more effective then the TB-WE in terms of
developing problem solving skills of teacher candidates. One of the the
most important difficulties which teacher candidates have are
determined as ‘understanding graph’ and ‘lack of basic knowledge’. As a
conclusion, if we try to develop candidate teachers’ problem solving skills,
both their readiness levels related to learning subject and general
readiness should be taken into consideration as it is one of the most
important factors affecting their problem solving skills.
