What characterizes scientifically based instruction?

The characteristic that defines scientifically based instruction is its foundation in credible research and peer-reviewed studies. This approach ensures that the instructional methods and strategies utilized in the educational setting are not merely anecdotal or based on personal preferences, but are instead grounded in evidence that has been rigorously evaluated by experts in the field. This reliance on validated research supports the effectiveness of the instruction and enhances student learning outcomes, as it incorporates strategies that have been proven to work across diverse educational contexts.

In contrast to other options, which might involve subjective opinions, personal experiences, or a focus on untested theories, scientifically based instruction is distinct in its commitment to using data and research findings to inform teaching practices. This ensures a level of reliability and accountability within the educational process.
