Online assessments may also lack the personal touch and rapport building that can occur during in-person interactions.
Advantages• Convenient• Can be adopted and implemented quickly.• Reduces or eliminates faculty time demands in instrument development andgrading.• Are scored objectively.• Provide for external validity.• Provide reference group measures.• Can make longitudinal comparisons.• Can test large numbers of students.Disadvantages• Measures relatively superficial knowledge or learning.• Unlikely to match the specific goals and objectives of a program/institution• Norm-referenced data may be less useful than criterion-referenced.• May be cost prohibitive to administer as a pre- and post-test.• More summative than formative (may be difficult to isolate what changesare needed).• Norm data may be user norms rather than true national sample.• May be difficult to receive results in a timely manner.

The Enterotube test, while convenient for identifying enteric bacteria, has several disadvantages. It may provide false positives or negatives due to the complex biochemical reactions involved, leading to misidentification. Additionally, the test is limited in its ability to differentiate closely related species and may not cover all possible pathogens. Furthermore, it requires a certain level of expertise to interpret the results accurately, which can be a barrier in some settings.
Some disadvantages of Benedict's qualitative test for reducing sugars include limited sensitivity compared to other methods, potential for false positives due to non-reducing sugars or other reducing substances, and lack of specificity for individual sugars. Additionally, the test requires careful control of temperature and timing for accurate results.
A pre-test and post-test loop allows for effective evaluation of changes in a process or program by measuring outcomes before and after an intervention. Advantages include the ability to assess the impact of changes and improve decision-making based on data. However, disadvantages may include potential biases if the testing conditions change between tests, and the possibility of participants altering their behavior due to awareness of being tested. Additionally, it can be resource-intensive, requiring careful planning and execution.
