Final answer:
Informal assessments after whole-group instruction help in monitoring individual student progress, assessing overall class comprehension, and identifying the need for remediation, through various formative assessment strategies.
Step-by-step explanation:
The purpose of implementing informal assessments after teaching a new concept during whole-group instruction is primarily to monitor individual student progress and assess overall class comprehension. Such assessments are formative in nature, aiming to gather immediate feedback on students' understanding of the material. Examples of informal assessments include Grasp Checks, which review concept comprehension, and Performance Tasks, where students apply what they have learned in practical situations. Additionally, Check Your Understanding questions and Practice Problems reinforce key concepts and provide opportunities for students to demonstrate their skills.
Informal assessments also allow educators to determine the need for remediation when students are struggling with the material. They can also prepare students for more formal assessments and essays by offering low-stakes opportunities to practice skills and articulate their understanding in a comfortable setting.
