Ms. Phillips currently teaches a remediation class to 8 students. The class is designed to help remediate students who struggle in science based on either their CRCT scores or their grade averages from the previous year. However, all of the students in the remediation class currently have an A or B in their current science class. Ms. Phillips seems to find that if she presents information at a lower level students seem to get bored and lose interest, and if she presents it at a higher level the students get frustrated. What are some good strategies or practices that Ms. Phillips could use as part of her science remediation class that will keep the students motivated and ensure success on future testing?
