The nonequivalent groups with anchor test (NEAT) design involves missing data that are missing by design. Three popular equating methods that can be used with a NEAT design are the poststratification equating method, the chain equipercentile equating method, and the item-response-theory observed-score-equating method. These three methods each…

The performance of 8- to 13-year-old monolingual English-speaking children with language impairment (LI) on seven nonlinguistic tasks was compared with two groups of typically developing children, monolingual English-speaking children, and proficient Spanish-English sequential bilingual children. Group differences were apparent, with a key finding…

In this study, students' use of a new educational Web portal was evaluated with particular emphasis on searching and browsing strategies. The effects and implications of a federated search system are also discussed. Fifty-four students, ranging from 5th to 12th grade, were given five tasks to complete using the SchoolRooms interface. The tasks…

In this article, Maria Martiniello reports the findings of a study of the linguistic complexity of math word problems that were found to exhibit differential item functioning for English-language learners (ELLs) and non-ELLs taking the Massachusetts Comprehensive Assessment System (MCAS) fourth-grade math test. It builds on prior research showing…

This research examined the nature of classroom decision making among three elementary teachers (the first in her 8th year, the second in her 3rd year, and the third in her 1st year). We were interested in understanding how teachers experience the complexity of classroom decision making and how they manage the cognitive load while teaching. The…

With the increasing use of dynamic media in multimedia learning material, it is important to consider not only the technological but also the cognitive aspects of its application. A large amount of previous research does not provide preference to either static or dynamic media for educational purposes and a considerable number of studies found…

The theme for the 58th annual conference of the Association of Literacy Educators and Researchers (ALER) was Bridging Cultures Through Literacy. In the first section of the Yearbook, Parker Fawson's presidential address captures the unique nature of ALER and its role in his professional development, and then moved beyond to capture the changing…

Large-class English teaching is an inexorable trend in many Chinese universities and colleges, which leads to a strange and serious phenomenon that most students' English is ironically but vividly described as "the dumb English". Therefore, cultivating students' communicative skills and developing their language competence has become a…

The level of learners' expertise has been used as a metric and diagnostic mechanism of instruction. This metric influences mental effort directly according to the applications of cognitive load theory. Cognitive efficiency, an optimal measurement technique of expertise, was developed by Kalyuga and Sweller to replace instructional efficiency in…

Basic issues in understanding Item Response Theory (IRT), or Latent Trait Theory, measurement models are discussed. These theories have gained popularity because of their promise to provide greater precision and control in measurement involving both achievement and attitude instruments. IRT models implement probabilistic techniques that yield…

Two experiments tested the Conceptual Dependency Theory, stating that verbs are represented in memory as combinations of actions and relations encoding underlying conceptual structure. Experiment I results supported the conceptual complexity hypothesis, while II rejected complexity for imagery as the predictor of performance. (CHK)

The development of a new technique, the Relative Difficulty Ratio (RDR), is described, as well as how it can be used to determine the difficulty level of a test so that meaningful inter-test difficulty comparisons can be made. Assumptions made in computing RDR include: 1) each item must be scored dichotomously with only one answer choice keyed as…

Two techniques for writing achievement test items to accompany instructional materials were contrasted: (1) generating items from statements of instructional objectives, and (2) generating items from rules for transforming instructional statements (adapted from Bormuth). Items of each type were written by two experienced item writers. Subjects…

Among children four to six years of age who were tested for their detection of melodic transformations, performance was superior for transformations that changed contour, for greater changes in contour, and for faster presentation rates. Melodies transformed by reordering tones were as discriminable as those transformed by inserting novel…
