Question 5

In the context of 'flipped classroom' methodology, what is the primary role of ICT for students BEFORE coming to the physical classroom?

Accepted Answer

C. To access and learn new content (e.g., through videos, readings) independently. — In a flipped classroom, the primary role of ICT for students before class (Option C) is to independently access and learn new content, typically through pre-recorded video lectures, readings, or online resources. This allows classroom time to be used for interactive activities, problem-solving, and deeper engagement with the material, rather than direct content delivery. Group projects (A), advanced problem-solving (B), and live discussions (D) are typically activities reserved for the in-class session.

Answer

A. To complete group projects and collaborative assignments.

Answer

B. To engage in advanced problem-solving sessions with the teacher.

Answer

D. To participate in live online discussions and debates with peers.

Question 6

A couple is planning to have a child. The father is a known carrier for a rare autosomal recessive genetic disorder, while the mother has no family history of the disorder and tests negative for the carrier gene. Based on this information, what is the probability that their child will be affected by this specific recessive genetic disorder?

Accepted Answer

A. 0% — For an autosomal recessive disorder, an individual must inherit two copies of the recessive allele (one from each parent) to be affected. In this scenario, the father is a carrier (heterozygous, e.g., Aa) and the mother is homozygous dominant (AA) as she tested negative and has no family history. A cross between Aa and AA individuals will produce only AA (unaffected) and Aa (carrier) offspring, meaning there is no possibility of an 'aa' (affected) genotype. Therefore, the probability of their child being affected is 0%.

B. 25%

Answer

C. 50%

Answer

D. 75%
