Final answer:
Option C provides the principal with critical insights into the candidate's problem-solving abilities and practical experience in addressing educational challenges, which is central to understanding their potential effectiveness in a low-performing school.
Step-by-step explanation:
Among the proposed interview prompts, option C, "Describe a significant problem you encountered in attempting to promote learning for one or more students, and explain how you addressed that problem," would likely provide the principal with the most valuable information about the candidate's effectiveness as an educator. This question requires the candidate to demonstrate problem-solving skills, adaptability, and practical application of pedagogical strategies. Their answer would reveal their approach to overcoming obstacles in the learning process, which is especially relevant in a school with a history of low performance.
Options A and B might yield information on the candidate's self-assessment or theoretical preparation but do not directly address the practical challenges of teaching. Whereas option D pivot significantly, focusing on curriculum knowledge, it may not adequately scope into effective teaching practices or problem-solving abilities, which are pivotal in enhancing student learning outcomes.
