The assessment of learning in large online courses requires tools that are valid, reliable, easy to administer, and can be automatically scored. We have evaluated an online assessment and learning tool called Knowledge Assembly, or Knowla. Knowla measures a student's knowledge in a particular subject by having the student assemble a set of…

Identifies and describes major factors interacting with readability measures in 36 experimental studies analyzing the validity of such measures. (RB)

Found that standard readability indexes by themselves are not useful in measuring readability and comprehensibility of income tax material. Also casts doubt on the use of only readability indexes to measure insurance, labor, and real estate contracts. (PD)

Investigates whether readability is a key criterion for college and university professors in selecting textbooks. Finds that many selected textbooks are at too high a level for the students. Suggests that students have a difficult time learning when the text is even slightly above their level. (PRA)

This document discusses the measurement of reading ability and the readability of books by application of the Lexile framework. It begins by stating the importance of uniform measures. It then discusses the history of reading ability testing, based on the assumption that no researcher has been able to measure more than one kind of reading ability.…

Investigates readability levels of correspondence sent out by Gulf Coast area business offices. Finds that a large majority of the correspondence sent out from the offices under study is written at too high a reading level. Finds also that the greatest problem lies in syllable intensity--the use of "big" words where everyday words would have…

Doubts the ability of formulas to predict readability and questions their use as aids in writing readable prose. Points out that formulas also hamper the teaching of business writing because they emphasize written products instead of the writing process. (PD)

A study was conducted to determine whether there was any match between student perception of reading ease and the readability of three main line, first-year college composition texts (Daugherty; Kinneavy, McCleary, and Nakadate; Lauer, Montague, Lunsford, and Emig) as determined by five commonly used readability formulas. Two chapters (on…

Readability has been gauged by such means as determining the length of individual words in a passage, analyzing types of sentences, and assessing numbers of subordinate clauses, prepositional phrases, modifiers, and so on. Probably the most successful formula has been the Dale-Chall method, which measures readability by determining the percentage…

The Flesch readability index yields meaningful information about the responses of readers to texts. Because the formula is so simple, a group of English teachers wrote a program in BASIC that would count some obvious surface features of a text and calculate Flesch scores. Among the programing problems encountered were counting words (taking into…

College students can read, but they often lack the prereading and postreading skills needed to help them think about and respond to what they read. A three-step plan can help students read and understand the text more fully. The first step entails using measures of fitness to determine: (1) the grade level of the text being considered and how it…

This paper shows how the concept of general objectivity can be used to improve behavioral science measurement, particularly as it applies to the Lexile Framework, a tool for objectively measuring reading comprehension. It begins with a dialogue between a physicist and a psychometrician that details some of the differences between physical science…

A study was conducted to determine if increasing the redundancy of sections in scientific articles where typical readers became bored or confused would have a desirable effect on other readers. Undergraduate journalism students applied R. F. Carter's signalled stopping technique to two different science articles by indicating points where they…

This document discusses in depth the theoretical background of the Lexile Framework, which is based on the assumption that reading comprehension is the best predictor of success in higher education and job performance, and that it is the most tested construct in education. The first section defines measurement and differentiates between specific…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 12 titles deal with the following topics: (1) the effect of writing instruction on reading comprehension and story writing ability; (2) eighth grade remedial students' concepts about reading and writing; (3) the effect of a…
