Final answer:
Effective testing strategies involve differentiating tests for different groups, using experiments, proving hypotheses wrong, and providing measurable and yes or no answers.
Step-by-step explanation:
Effective testing involves various strategies that aim to ensure accuracy, fairness, and usefulness. One strategy is differentiating tests for different age groups, abilities, and contexts. Researchers like Jack A. Naglieri have developed or improved testing programs to achieve these goals. Additionally, effective testing strategies include using experiments to collect evidence, proving hypotheses wrong, providing measurable results, and yielding yes or no answers.
