This guide is intended for use in developing informational materials intended to be read by adults with limited reading skills. Most of the examples used throughout the guidelines relate to food and nutrition; however, the concepts they illustrate are applicable to any topic. The following topics are covering: knowing a written message's intended…

Parts 1 and 2 (SE 524 424 and 527 089) described Flesch readability for determining a text's reading level and results of applying the test to astronomy/physics textbooks. This part presents results for a new sample of texts, including calculus-level texts. A comparison with high school physics texts is provided. (JM)

The present findings imply that a readability formula is not an effective writing production criterion, even when the writer does not deliberately write to the formula. Comprehensibility of text might be better controlled through the proper use of the transformer concept (MacDonald-Ross and Waller). (Author/PN)

A readability formula for elementary Spanish instructional materials was developed by building on previous research, particularly in regard to the application of the Fry readability graph to Spanish language materials. The study began with the selection of average sentence length and number of syllables per 100 words as independent variables.…

One of a series dealing with current issues affecting language arts instruction, this paper focuses on the conceptions and misconceptions of readability. The paper begins by noting that over the years, researchers in readability have had two major goals: to determine what makes written materials easy or difficult to read and comprehend, and to…

The revised Spache Readability Formula and the Fry Readability Formula were applied to 20 selected reading materials designed for adolescents reading at second grade level. Three samples from each text were examined. The results using the Spache formula corresponded to the publisher's stated readability levels, with no significant variability…

Spanish and English readability formulas were applied to sample passages from learning materials and textbooks used in bilingual classrooms in order to ascertain their analytic and predictive capabilities. Two main factors, word difficulty and sentence difficulty, accounted for most of the total variance in readability research using factor…

Reviews research findings about community college students' reading skill levels; the discrepancy between reading levels and the difficulty of college-level reading materials; reading program characteristics and effectiveness; textbook readibility formulas; and other methods of evaluating textbooks. Offers recommendations for reducing the…

Investigates reliability of two approaches for estimating text difficulty at the first-grade level: the Scale for Text Accessibility and Support and the Fountas/Pinnell system. Supports the predictive validity of the two rating scales with performance data. Suggests potential benchmarks for first-grade performance: 95% accuracy; 80 words per…

Provides step-by-step procedures for developing an index which uses the Gunning Fog technique to evaluate the level of reading difficulty of textbooks. Cites examples, illustrations, and several warnings in the discussion. (RT)

Readability formulas applied to materials for hearing-impaired students do not account for important factors in reader-writer-text interaction. Factors include the reader's purpose, cultural background, and extent of background knowledge; writers' assumptions about readers; the text's structure, content, and cohesion; and the role of…

After reviewing criticisms of the exclusive use of readability formulas to evaluate text difficulty and describing successful efforts to broaden the traditional readability formula approach, this report presents a 20 item checklist for determining text comprehensibility based on four criteria: (1) specific objectives or outcomes expected from the…

Readability formulas have varied uses. In education they are used to match children's reading ability to the difficulty level of material, select stories and books for classroom use and for individual students' particular needs, select textbooks and other reading materials, aid educational research, and check reading materials of newly literate…

A three-part correlational study examined the explanatory power of the Lexile theory of reading comprehension, which was based on the semantic and syntactic components of prose. Correlations were performed between the item difficulties of nine nationally normed reading comprehension tests and computer generated difficulties which were reported in…

Describes a study that examined the readability of papers "College and Research Libraries" accepted, rejected, and published for 1990 and 1991. Results showing a statistically significant difference for the text of papers but not for abstracts are reported, and topics for further research are suggested. (Contains six references.) (EAM)
