Literature relating summarization skills to reading improvement and to test score gains is reviewed, and two new studies are reported. One study compared gain on the Test of English as a Foreign Language (TOEFL) of two groups of students, one (n=7 students) receiving instruction in summarizing skills and the other (n=14) receiving TOEFL preparation from commercially prepared TOEFL materials. Results show the groups instructed in summarizing gained an average of 7 points, and the other group gained 13 points, on average, a statistically insignificant difference. The second study compared TOEFL score gains of two additional groups of English-as-a-Second-Language (ESL) students who had been in ESL classes in the United States for 9 months. One group (n=61) reported using summarization skills in class; the other (n=25) reported never using them. Over the 9 months of ESL study, the group using summarization skills had an average TOEFL score gain of 61 points, and the other group's gain averaged 42 points. Contains 22 references. (MSE)
