https://www.selleckchem.com/products/D-Cycloserine.html This study aimed to compare the students' scores of the spot (spotter/classical/traditional/tag/ring/bell-ringer) test (3D environment) performed in the laboratory with the slide test (gross anatomy images) (2D environment) in the class. The observation of our department regarding both types for practical examination was reported, in terms of exam marks of the students. Both are preferred as the practical examination types for gross anatomy course our in medical faculty. The 29 blocks' scores in 5years (2013/2014-2017/2018) belonging to first- and second-year medical students' spot tests and slide tests are evaluated retrospectively and statistically compared. Correlations of the spot tests and the slide tests, besides the correlations between theoretical examinations and the practical examination types, are calculated. Spot test scores were significantly higher (p < 0.05) in nine blocks, while slide test scores were higher significantly (p < 0.05) in fourteen. There was no statistically significant difference between the practical examination types (spot/slide) in six blocks. There were correlations between the spot test and the slide test in all blocks (p < 0.001). It is considered that the spot test reflects the success/ability in a 3D environment, while the slide test reflects it in the 2D environment. In conclusion, neither of these two types of examinations stands out absolutely. Both types of examinations have their own features in areas, such as assessment power, applicability, and effect on success.
