Avci Akbel, B. (2018). A review on effectiveness of cello etudes created for longas and syrtos. Eurasian Journal of Educational Research, 75, 1-18. https://eric.ed.gov/?id=EJ1181464

q2 · i? · causal · r1

In the same N=8 pretest-posttest control group experiment, Expert 1's rubric scores (Table 2, e.g., TMV-post means 28,56 control vs 21,69 experimental) favored the control group; the article states the etudes were "not found to be successful by Expert 1."

"When the results of both groups were examined for Expert 1, it was observed that the evaluation scores of the control group were higher than the evaluation scores of the experimental group in both the pre-test and posttest. The data show that the etudes applied to the experimental group between the pre -test and the posttest were not found to be successful by Expert 1."
