Past research shows the imperative nature of students having a high knowledge of vocabulary, particularly as it relates to their level of reading comprehension. This is especially true in the areas of science and social studies because of the nature of the subjects and their corresponding texts. Students' ability to retain and recall vocabulary knowledge is, therefore, also critical. Educators use many different strategies and methods as means to these ends. One game frequently used for a review of information and to help students retain information is a modified version of the game BINGO. The researcher asked the question, therefore, whether or not this strategy is more effective than a simple "fill in the blank" worksheet review. In this study, the researcher compared the test scores of two different groups of fourth grade students. Both groups studied social studies vocabulary words in the same manner, the difference being that at set times throughout the study, one group reviewed the words using an independent worksheet review and the other used a modified BINGO game review. The hypothesis was that students participating in the modified BINGO game review of the vocabulary words would show no difference in test scores, at the .05 level of significance, when compared to those students who participated in the worksheet review. Both the control (worksheet) and experimental (BINGO) groups studied the same vocabulary words throughout the four weeks of the study. The students learned 4 each day (16 for each week) and then reviewed those 16 words on the fifth day of each week. After two weeks, a teacher-made test was given to both groups and the groups were then switched, each receiving the opposite treatment. Another test was given on the second set of 32 words at the end of the second half of the study. When the results of the test scores were analyzed using a paired t-test it was found that although the experimental group (the group using the BINGO game review) did achieve a higher average score, the research was not statistically significant based on the .05 level of significance. Therefore, the researcher retained the original hypothesis. Appendixes contain permission letters, a sample review worksheet, and a sample vocabulary test.
