Successful Lesson Plan Assessment

My cooperating teacher just gave the students a unit test which covered the material my observed lesson plan was on. A portion of my lesson plan had the students play a Jeopardy game and filled out a chart which consisted of eight of the American English colonies and characteristics of each. As each group of students chose one of the characteristic categories from the game board and point value, they were given a question to answer. If the team got the answer correct they got the points. However, if they answered incorrectly the other two teams had the chance to steal the points. In the end, if neither of the three teams got the answer correct I read the answer to them for them to wrtie down on their chart. While we played Jeopardy each student filled out the chart and that was their study guide for the test. I used an exit slip as my closing assessment however the 'real' assessment would be the unit test. My cooperating teacher has me grade the multiple choice and matching on his unit tests and then he grades the open response question. The grades were all over the board. There were fourteen multiple choice/matching questions on the test and I had some students only get one to three wrong and other students were getting nine or more wrong. Fortunately, the majority of the students performed extremely well on the 'colony characteristics' portion of the test. Even those students who got nine or more questions wrong scored well on that portion of the test. It felt great knowing that the portion of the unit that I taught was what the majority of the students performed well on. However, when the students who perforemed poorly on the test still did well on the 'colony characteristics' portion I knew that something had to be adjusted in the way the material was taught. Overall, it was nice to see students perform well on the material I taught but I believe some adjustments need to be mad to help those students who consistently score poorly to perform better on the tests.
