Summary
Internal assessments effectively predict medical student success in final exams. This continuous assessment method shows high diagnostic accuracy in identifying students at risk of failing professional examinations.
Area of Science:
- Medical Education
- Assessment and Evaluation
Background:
- Continuous assessment is integral to medical education.
- Internal assessments are a key component of continuous evaluation.
Purpose of the Study:
- To evaluate the predictive accuracy of internal assessment scores for final summative examination outcomes in medical students.
Main Methods:
- A diagnostic accuracy study was conducted with 2nd-year medical students.
- Receiver Operating Characteristic (ROC) curve analysis was used to determine accuracy.
- Teaching methods included lectures, case-based sessions, and practicals.
Main Results:
- The study included 202 students (60.4% male).
- Internal assessment demonstrated 100% sensitivity and 91% specificity at a cut-off value of 27.5.
- Mean scores for the final exam and internal assessment were 131.71±19.81 and 36.18±8.03, respectively.
Conclusions:
- Internal assessment possesses significant diagnostic power.
- It effectively identifies students likely to fail professional examinations.

01:15Receiver Operating Characteristic Plot
491
A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

01:21Precipitation Titration Curve: Analysis
1.9K
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...
