Answer:
In the past, learners were required to achieve at least 50% in four specific designated subjects that were the same nationwide. However, this was recently changed - the new requirements include attaining the same percentage in any four subjects that have 20 credits from a list of subjects.
This change has certain advantages and disadvantages. The advantage is that there will be more students with better percentages applying for various high education institutions as it should now be easier for them to pick subjects they are most confident in and that will be relevant for their further education. Their focus will also be on those most important subjects for them and their studies instead of on something they might not even need in their future career.
However, a disadvantage is that students might pick subjects they find easiest just to secure their place in a university. Those subjects ultimately might not provide them with needed strategies for thinking and learning that otherwise designated subjects might have. Furthermore, some higher education institutions might have their own lists of designated subjects and minimum entry requirements that might not be the same as the student's choices.
Answer: Construct validity
Explanation:
Construct validity is the degree to which a test is done to measure what it claims. Construct validity defines how well the test or experiment actually measures its claims and whether the operational definition of the variable reflect the true theoretical meaning of the concept being illustrated.
The psychologist develops a questionnaire that is designed to study the variable of self-esteem and then conducts different studies to investigate the differences between people who had low scores on sled esteem and the people who had high score on self esteem. The reason for this was to get an accurate method of measuring self esteem. This means the psychologist wants to establish construct validity.
They manipulated the length of time between seeing and recalling sets of 3-letter stimuli while preventing rehearsal.
