Research has shown that frequent low stakes quizzes drastically improve student learning and understanding (make it stick: The Science of Successful Learning, Peter C. Brown, Henry L. Roediger III, & Mark A. McDaniel).  This means creating quizzes that give students immediate feedback as to why an answer is correct or incorrect.  This allows students to identify misconceptions, reinforce concepts and ultimately gain a deeper understanding of the content. 

I have set up frequent low stakes castle learning quizzes throughout each unit in order to promote active learning and spacing them out throughout the unit allows for greater retention.  The best part of castle learning is that it provides immediate feedback for students with explanations of right and wrong answer choices.  

After a successful year using google classroom to deliver paperless labs I am looking forward to taking this concept a step further.  I will be continuing to use google forms/docs as a data sheet for students to input their data in class.  This counts for 50% of their lab grade and is due at the end of class.  The remaining 50% of their lab grade will come from either a lab quiz (posted on google classroom in a google form quiz) or a conclusion utilizing the CER (claim, evidence, reasoning) format.  These are due on Monday of the following week. The idea is to quiz students on the more procedural labs and have them analyze and justify their results in the more inquiry based labs using CER format.
