Preteaching versus concurrent teaching of component skills of a subtraction algorithm to skill‐deficient second graders: A components analysis of direct instruction

This study examined the effectiveness of a preteaching strategy as a subordinate procedure of Direct Instruction.Skill‐deficient second‐graders were provided with repeated trials on a selected component skill of a subtraction algorithm beforethey worked the entire algorithm and compared with students who, from the beginning of training, received systematic instruction on working the entire algorithm. Statistically significant differences favouring the preteaching strategy group were found on periodic probe measures taken during training but not on a 12‐item post test nor on a ten‐problem maintenance test administered eight days later. Implications for using preteaching as an instructional procedure for inducing efficiency in the use of problem‐solving strategies are discussed.     

Design and development research: a model validation case

This is a report of one case of a design and development research study that aimed to validate an overlay instructional design model incorporating the theory of multiple intelligences into instructional systems design. After design and expert review model validation, The Multiple Intelligence (MI) Design Model, used with an Instructional Systems Design (ISD) Model, was tested for use by four practicing instructional designers. Instruction developed for learners using this model was then evaluated measuring post-test and attitudinal scores with 102 participants. This report also provides a reflection on the lessons learned in conducting design and development research on model validation. The procedures and findings have implications for the processes involved in instructional design model validation through designer use and program implementation.

Associations between Fine Motor and Mathematics Instruction and Kindergarten Mathematics Achievement

Research Findings: This study investigates the role of fine motor and mathematics instruction in mathematics achievement in an international sample of kindergarteners from the United States and China. Multilevel modeling was used to assess the interaction between students’ entering skills and classroom time spent on basic math, higher-order math and fine-motor instruction. For American children, the effect of basic math and higher-order math instruction on student achievement depended on entering skills; however, fine motor instruction had negative average effects on student achievement and did not depend on students’ entering skills. Instruction time was not a significant predictor of achievement for Chinese students. Practice or Policy: Though fine motor skills have a robust correlation with mathematics achievement, a causal link has not been established. Our study indicates that time spent in fine motor instruction does not advance mathematics achievement in kindergarten and in fact may weaken mathematics achievement, given the limited time in the instructional day. American teachers in our sample who spent more time in fine-motor instruction tended to spend less time on basic math and higher-order mathematics instruction. Educators should weigh instructional trade-offs carefully and work to tailor instruction to students’ skill levels.     

A psychoeducational model of counseling

The relevance of this model for instructional and counseling research are discussed.     

Using the Expressive Writing Program to Improve the Writing Skills of High School Students with Learning Disabilities

Abstract. The complex nature of written expression presents difficulty for many students, particularly those with learning disabilities (LD). The literature in the area of written expression and students with learning disabilities indicates that explicit, rule‐based instruction can enhance the writing skills of struggling students. Research in Direct Instruction (DI) writing programs is promising, but limited at this time to a small number of group design studies. The purpose of this study was to investigate the effects of the DI writing program, Expressive Writing, for high school students with learning disabilities using a single‐subject design methodology. Results indicated that the Expressive Writing program improved the writing skills of the students in this study. Students also were able to generalize and maintain the writing skills learned during intervention.

English Reading Effects of Small‐Group Intensive Intervention in Spanish for K–1 English Learners

In this article we report small, but statistically significant, effects of brief supplemental instruction on English reading by Spanish‐speaking kindergartners (N = 37) who performed poorly on a bilingual battery of phonological‐processing tasks. Intervention design was compatible with the Reading First initiative and with research on use of multitiered intervention strategies for preventing reading failure among young monolingual students (e.g., L. S. Fuchs & Vaughn, 2003). We describe a Core Intervention Model (CIM) comprised of specific instructional behaviors that teachers might easily learn and employ regardless of curriculum, and discuss implications of our findings for building multitiered preventative instruction for young English learners.

Designing online courses: A taxonomy to guide strategic use of features available in course management systems (CMS) in distance education

Course developers can be distracted from applying sound instructional design principles by the amount of flexibility offered through online course development resources (<citeref rid="b16">Kidney & Puckett, Quarterly Review of Distance Education, 4 (2003)</citeref>, 203-212). Distance education course management systems (CMS) provide multiple features that can be easily integrated into online instruction. Easy integration does not equal good design, and poor design can impede learning (<citeref rid="b15">Kearsley, A guide to online education (1997)</citeref> http://gwis.circ.gwu.edu/～etl/online.html). A taxonomy of the instructional value for CMS features is described. An example of how a course was translated into an online version, initially a failure, and redesigned using this taxonomy is presented. A taxonomy that strategically guides the use of appropriate CMS features to integrate informational, instructional, and learning elements into online courses can support designers in the development of quality of online instruction.     

Customizing Instruction to Maximize Functional Outcomes for Students With Profound Multiple Disabilities

This article describes a process for customizing instruction for students with profound multiple disabilities that has been used to design instructional programs and maximize the attainment of functional outcomes for students. The process focuses on collaborative teamwork and problem solving to design and implement instructional programs by ensuring that the 5 components of the process are included. Team members determine (a) prepositioning handling procedures; (b) overall body positioning for instruction; (c) hand, arm, and head positioning; (d) instructional adaptations and materials; and (e) handling procedures to combine with systematic instructional strategies.     

Instructional Sensitivity of a Complex Language Arts Performance Assessment

Validation of assessments intended to improve instruction and learning should include evidence of instructional sensitivity. This study investigated the instructional sensitivity of a standards-based ninth-grade performance assessment that required students to write an essay about conflict in a literary work. Before administering the assessment, teachers of 886 ninth-grade students were randomly assigned to one of three instructional groups: literary analysis, organization of writing, and teacher-selected instruction. Despite the short duration of instruction (8 class periods), results support the instructional sensitivity of the assessment in two ways: Instruction on literary analysis significantly improved students' ability to analyze and describe conflicts in literature, and instruction on the organization of writing led to significantly higher scores on measures of coherence and organization.     

Productive failure in mathematical problem solving

This paper reports on a quasi-experimental study comparing a “productive failure” instructional design (Kapur in Cognition and Instruction 26(3):379–424, 2008) with a traditional “lecture and practice” instructional design for a 2-week curricular unit on rate and speed. Seventy-five, 7th-grade mathematics students from a mainstream secondary school in Singapore participated in the study. Students experienced either a traditional lecture and practice teaching cycle or a productive failure cycle, where they solved complex problems in small groups without the provision of any support or scaffolds up until a consolidation lecture by their teacher during the last lesson for the unit. Findings suggest that students from the productive failure condition produced a diversity of linked problem representations and methods for solving the problems but were ultimately unsuccessful in their efforts, be it in groups or individually. Expectedly, they reported low confidence in their solutions. Despite seemingly failing in their collective and individual problem-solving efforts, students from the productive failure condition significantly outperformed their counterparts from the lecture and practice condition on both well-structured and higher-order application problems on the post-tests. After the post-test, they also demonstrated significantly better performance in using structured-response scaffolds to solve problems on relative speed—a higher-level concept not even covered during instruction. Findings and implications of productive failure for instructional design and future research are discussed.     

Teaching domain-specific skills before peer assessment skills is superior to teaching them simultaneously

Instruction in peer assessment of complex task performance may cause high cognitive load, impairing learning. A stepwise instructional strategy aimed at reducing cognitive load was investigated by comparing it with a combined instructional strategy in an experiment with 128 secondary school students (mean age 14.0?years; 45.2% male) with the between-subjects factor instruction (stepwise, combined). In the stepwise condition, study tasks in Phase 1 were domain-specific and study tasks in Phase 2 had both domain-specific and peer assessment components. In the combined condition, these two components were present in all tasks in both phases. Final performance (i.e. speed and accuracy in domain-specific skills and peer assessment skills) showed no significant differences, but performance improved more from Phase 1 to Phase 2 in the stepwise condition than in the combined condition. The results suggest that, with complex study tasks, it might be beneficial to teach domain-specific skills before peer assessment skills.     

Elaboration theory and cognitive psychology

Increasingly, instructional literature is pointing out the need for theories of instruction which are consistent with emerging cognitive psychology. Theory construction of this sort entails taking into account developing notions of the learner as a processor of information rather than a respondent to stimuli. The purpose of this article is to describe a recent instructional effort, referred to as the Elaboration Theory of Instruction (ETI), and chart its correspondence with several major principles drawn from contemporary cognitive psychology. The ETI incorporates models for both the sequencing and structuring of subject matter. The article will show how these components relate to current models of knowledge representation, schema theory, memory processes such as storage and retrieval, and earlier cognitive based instructional frameworks.     

The current status of instructional design theories in relation to today's authoring systems*

It is of course very difficult to accurately project important characteristics of the future state of any rapidly evolving field, and the field of authoring systems for computer‐assisted instruction (CAI) is no exception. However, strong trends in evolving CAI systems of today would seem to indicate some important characteristics of the software systems underlying tomorrow's automated instructional systems. Under the premise that form follows function, this paper will explore the functional impetus of some of the most important trends extant in terms of their roots in a powerful, emerging technology of instructional design. This technology promises to complement the advancing hardware and software technologies, by supplying that sine qua non of successful instructional materials. It is inevitable that systems of the future will make (and indeed are making) significant accommodations of this vital technology as it matures, and therefore some important characteristics of tomorrow's systems can be predicated upon what is already known of this technology of instructional design.     

Special Education Teacher Education: A Perspective on Content Knowledge

The passage of No Child Left Behind and the Individuals with Disabilities Education Act has strengthened the conditions for instructional accountability for all learners. The standards‐based approach promulgated by curriculum and state assessments is central to the accountability of conditions in today's schools; however, national and state data continue to document a performance gap between students with learning disabilities (LD) and their nondisabled peers. Building on 5 years of experience in developing and testing the Blending Assessment with Instruction Program in mathematics, we present three basic principles that are essential to ensuring that students with LD achieve curriculum standards: (1) instruction must be aligned with curriculum standards, (2) teachers' content knowledge is essential to translating curriculum standards into aligned instruction, and (3) instructional methodology should receive greater attention during teacher preparation.     

Using Explicit and Strategic Instruction to Teach Division Skills to Students With Learning Disabilities

Students with mathematics learning disabilities (LD) exhibit difficulties with retrieval and cognitive skills that impede their ability to perform basic mathematical skills. Instruction in mathematical procedures (i.e., procedural knowledge) is necessary to help students learn and apply skills such as basic facts and whole-number computation. Division is a skill that is identified in curriculum across the grade levels; yet, it is a skill that is often taught last in instructional sequences because of its complexity and prerequisite knowledge. Reviews of research have revealed that students with LD benefit from a combined model of academic instruction that includes both explicit and strategic instructional procedures. This article presents an overview of division instruction and a sample of interventions for teaching division that include explicit and strategic instructional procedures, which are found in the combined model of teaching.
