A longitudinal study of students' developing understanding of decimal notation has been conducted by testing over 3000 students in Grades 4 to 10 up to 7 times. A pencil-and-paper test based on a carefully designed set of decimal comparison items enabled students' responses to be classified into 11 codes and tracked over time. The paper reports on…

This study compared effectiveness of either a concrete-representational-abstract (CRA) or a representational-abstract (RA) instructional sequence in teaching fraction concepts to 50 middle school students with mathematics disabilities. On all achievement measures, students in the CRA group had overall higher mean scores than did students in the RA…

Nine children participated in one of three groups: children diagnosed as both sensory and language impaired, children diagnosed as language impaired, and normally developing children matched for language level. Sensory integration activities prior to language intervention resulted in significant changes on the Battelle Developmental Inventory for…

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…

This article examines alternating verbs (such as "quemar"(se) "to burn") in second language (L2) Spanish by considering the learnability problem from a sequence learning perspective (N. Ellis, 1996, 2002). In Spanish, verbs of the alternating class are obligatorily marked with the clitic "se" in their intransitive form. Errors of omission among…

Purpose: Verb processing in early sequential Spanish-English bilinguals was investigated. Primary study goals were to identify potential patterns of development in relative levels of verb processing efficiency in a 1st (L1) and 2nd (L2) language and to investigate factors influencing cognitive control of the dual-language system in developing…

An examination of student papers from three universities on the same tasks revealed that expository writing tasks were less demanding cognitively than argumentative writing tasks and that argumentative writing tasks were less demanding than speculative tasks. Another finding was that when students were able to translate a generalized task into…

With the advent of the computer as an instructional tool many curriculum specialists have been designing software for reading instruction. However, most of the software designed to help develop reading comprehension skills does not consider the inclusion of monitoring comprehension strategies, therefore limiting the instructional potential of the…

This study investigated the effects of different structures of a synthesizer and formats of the generality component on the application and remember levels of learning. Seventy-three undergraduates participated. Four treatment groups were formed by combining two types of structure (complete versus partial) with two types of format in generality…

Different kinds of basic knowledge and strategies necessary for comprehension are examined in three radically different domains: (1) the stories, (2) mathematical problems, and (3) electronic circuits. From analyzing the comprehension processes in these different domains, similarities have emerged in the role of planning knowledge and the…

An instructional program based on a learning hierarchy and involving the addition of fractions was presented to fourth grade students in a pretest - posttest design. The results of the tests were analyzed using both Walbesser's and White's techniques for validation. There was sufficient disagreement in the results to prevent a conclusion of…

Ninety-five secondary students were given textbook material in which two sequence variations (web and linear) were used in relation to the information processing strategies (serialist or holistic) demonstrated by the students. Users of the web-structured sequence scored higher on concept retention. (Author/JJD)

Computer-naive university students (N=124) were taught the BASIC programing language by solving and receiving feedback on program comprehension problems stated in BASIC or on corresponding problems stated in English followed by problems stated in BASIC. Results support a sequential method of instruction beginning with use of natural language…

Examines the relationship of sequential patterns of instruction and individual pattern components (including task presentation, student response, and teacher feedback) to the overall effectiveness of music lessons taught by elementary education majors. Indicates that there were no differences in teacher effectiveness scores based on instruction in…

A total of 132 volunteer 10th and 11th grade students participated in an experiment to investigate two variables of computer-based adaptive instructional strategies for concept learning. The first variable tested the hypothesis that selection of number of examples according to on-task information is more efficient than selection according to…
