Question: A student reads a claim that 'eating dark chocolate improves memory' based on a single person's personal blog post. Apply the concept of empirical evidence to explain what kind of information the student should seek instead to evaluate this claim.
Sample answer: Instead of a personal blog post, the student should seek information and data that have been systematically collected through scientific research and direct observation. This objective evidence is required to evaluate the alternative explanations and validate the claim about dark chocolate.
Key points:
- Reject personal blog posts/testimony in favor of systematically collected data
- Seek data collected through scientific research and direct observation
- Use this objective evidence to evaluate alternatives and validate the claim
Rubric: Grading Rubric: - Applies concept by rejecting personal testimony/blog posts. - Identifies the need for systematically collected information/data. - Specifies the need for scientific research or direct observation. - Links this to evaluating alternatives and validating the claim.
