Why is it necessary to assess students before during and after the lesson?

Assessing students before, during, and after a lesson is essential for understanding their prior knowledge, monitoring their progress, and evaluating their comprehension of the material. Pre-assessments help tailor instruction to meet students' needs, while formative assessments during the lesson allow for real-time adjustments to teaching strategies. Post-assessments provide insights into student learning outcomes and areas that may require further reinforcement. This continuous feedback loop ultimately enhances the effectiveness of instruction and supports student success.
