Another limitation is the . Every experiment has a predetermined outcome—measure g, find the refractive index, verify Ohm’s law. There is little room for students to design their own apparatus, troubleshoot unexpected results, or explore systematic deviations as research opportunities. This contrasts with modern pedagogical trends emphasizing “investigative labs” where the experimental question is not given in advance.
A very specific topic!
External examiners frequently ask about precautions. The manual highlights specific "do's and don'ts" for every setup—such as avoiding parallax error in optics or preventing overheating in electronic circuits.
