This paper begins by providing an overview of three types of textbook research methods: asking teachers, parents, or students about the different aspects of textbook quality; textbook analysis, i.e. counting some characteristics of a textbook using strictly fixed rules; and the experimental evaluation of textbooks, usually carried out in schools.…

Examines the "levels effect" (the theory that more important text elements are more likely to be remembered than less important elements) in children and adults when reading expository text. Finds differences between adults and children in the extent to which they engaged in the type of processing that resulted in levels effects. (MG)

The effect of equations in scientific proofs on readers' comprehension was studied. Forty college undergraduates solved unfamiliar physics problems with or without a traditional series of related equations. Verbal proofs produced better responses than did equation-based proofs. Equations in proofs cause readers to shift attention away from…

Compares and contrasts chapters from two children's science textbooks, one published in 1992 in a traditional format, and the other in 1995 using a new format. Finds them very different in terms of structure and organization. Shows that children respond to these texts very differently. Shares some ideas about teaching with such texts. (SR)

We report 3 studies investigating children's and adults' interpretation of ambiguous focus in sentences containing the focus-sensitive quantifier only. In each experiment, child and adult participants compared sentences with only in a preverbal position and counterpart sentences without only against a series of pictures depicting events that…

Determines that the complexity of syntax does not significantly affect reading comprehension of native and non-native English speakers when reading technical writing. Finds no significant differences between subgroups reading an authentic computer science text and those reading a syntactically adapted text, either in comprehension or in speed. (MG)

Describes a study of undergraduates that examined differences in computer screen formats and their effects on search time and strategy. Row, diagonal, and column information formats are compared, as well as tightly packed and loosely packed displays, and results of regression and residual analyses are discussed.

The effects of conceptual change text and application questions in 139 college students' learning of electricity concepts were investigated. The experiment was a 2X2X2X2 factorial. Compared to traditional text and no questions, conceptual change text and application questions, respectively, improved acquisition of qualitative concepts.…

Investigates whether 11-year-old children in Singapore, from English Dominant or English Non-Dominant backgrounds, read better orally when words were presented in list or text. Finds that readers with less exposure to English relied more on contextual information than more experienced readers, and that reading miscues varied according to whether…

A study examined the first grade materials in five new basal programs submitted for the 1993 Texas state adoption. (The programs were those of Harcourt Brace Jovanovich; Houghton Mifflin; Scott Foresman; Macmillan/McGraw-Hill; and Silver Burdett Ginn). These series are compared with program materials currently in use in the state. The analysis…

One source of potential difficulty for struggling readers is the variability of texts across grade levels. This article explores the use of automatic natural language processing techniques to identify dimensions of variation within a corpus of school-appropriate texts. Specifically, we asked: Are there identifiable dimensions of lexical and…

Efforts to improve civic education face a conundrum. On the one hand, students report that they are more likely to learn about democracy and citizenship through reading textbooks than through any other activity and according to the National Education Association, reading is the gateway to learning in all content areas. However, reviews of textbook…

A study investigated whether children reading an informational story recalled more information and perform better on a delayed test than those who read a textbook containing many of the same ideas. Subjects, 58 fifth-grade students from a suburban public school with approximately equal percentages of African-American and Caucasian children from a…

Presents the theoretical framework for examining texts in educational contexts. An actual reading lesson is analyzed in terms of the text structure and content, the nature of student-teacher interaction with the text, and post-reading discussion of the text. Tables outline the text structure and contrast teacher manual recommendations to actual…

Verbal-retelling abilities for social-studies lectures were examined in 20 adolescent boys with language-learning disabilities and 29 with normal language abilities. Lectures had either a comparison expository discourse structure or a causation discourse structure. Results indicated that the comparison discourse structure facilitated more…
