Classroom applications of mnemonic instruction: acquisition, maintenance, and generalization.

This investigation evaluated the effectiveness of classroom mnemonic instruction of science content, for 19 students with mild disabilities. Students were given either mnemonic instruction or more traditional instruction in a within-subjects design, in which treatment order was counterbalanced across classrooms, for each of two weekly units in life science. Following a third week of mnemonic instruction, students were taught to generate and draw their own mnemonic pictures. Results suggested that mnemonic instruction resulted in substantial increases in initial content acquisition, and substantially higher delayed-recall scores, over more traditional instructional procedures. Further, it was found that trained students were able to successfully generate and apply their own mnemonic strategies to novel content. Students overwhelmingly preferred mnemonic instruction over traditional instructional methods.     

The effectiveness of a highly explicit, teacher-directed strategy instruction routine: changing the writing performance of students with learning disabilities

This study examined the effectiveness of a highly explicit, teacher-directed instructional routine used to teach three planning strategies for writing to fourth and fifth graders with learning disabilities. In comparison to peers who received process writing instruction, children who were taught the three planning strategies-goal setting, brainstorming, and organizing-spent more time planning stories in advance of writing and produced stories that were qualitatively better. One month after the end of instruction, students who had been taught the strategies not only maintained their advantage in story quality but also produced longer stories than those produced by their peers who were taught process writing. However, the highly explicit, teacher-directed strategy instructional routine used in this study did not promote transfer to an uninstructed genre, persuasive essay writing. These findings are discussed in terms of their relevance to effective writing instruction practices for students with learning disabilities.     

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.     

The comparative effects of teacher-demonstration and self-paced instruction on concept acquisition and problem-solving skills of college level chemistry students

A comparison is made of the relative effectiveness of teacher-demonstration and self-paced modes of teaching concepts and problem-solving skills in chemistry. Sixty students were randomized into two treatment groups. A self-paced instructional package was used by subjects in the self-paced group. Subjects in the second group were taught by a teacher who used the same self-paced package. Results of the analyses of variance performed showed that the selfpaced mode of instruction was significantly more effective for teaching concepts and problem-solving skills. An attitude test was given at the end of the third unit. Results of the test showed that most students preferred the self-paced instruction to the teacher-demonstration method.     

Cognitive task analysis for instructional design: Applications in distance education

The increasing complexity of the subjectmatters taught through distance education calls for a cognitive approach to instructional design. Cognitive task analysis‐based instructional design (CTA‐BID) is especially appropriate for distance education, which requires high‐fidelity instructional materials that teach cognitive content with little or no classroom instruction. CTA‐BID organises instructional materials around the results of a cognitive task analysis that identifies the optimal knowledge structures, mental models, strategies, and skills underlying expertise in the subject matter. CTA‐BID has produced innovative instructional programmes aimed at teaching cognitive skills, accelerating the development of expertise, and improving student performance and training efficiency. This article provides an overview of CTA‐BID and its applications in the design of instructional and testing materials for distance education. I also review recent developments in education, psychology, and instructional design that complement CTA‐BID.     

The efficacy of reciprocal teaching in fostering the reading literacy of students with intellectual disabilities

The purpose of this study was to investigate the effects of strategy instruction on the reading literacy of students with mild and moderate intellectual disability. Students aged 15–21 with intellectual disability (n=35) participated in 24 sessions of literacy strategy instruction (experimental condition) or remedial literacy‐skill acquisition‐ lessons (control condition). The main objective of strategy instruction was to foster comprehension monitoring. Through shared dialogues, students were trained to generate questions about text, to summarise what was read, to clarify difficult words and to make predictions. The strategies were taught using the reciprocal teaching method developed by Palincsar and Brown. This method involves provision of support adjusted to students’ difficulties and peer teaching of strategies. Control subjects were exposed to direct instruction of basic reading skills that were presented sequentially and practiced solitarily by the students. Opportunities were given to respond to questions and to summarise but no strategy instruction was provided to foster comprehension monitoring. Two different measures of comprehension and a measure of strategy use were administered to test for variation across different methods of instruction. Findings on all measures provide support for the claim that strategy instruction is indeed superior to traditional remedial methods of skill acquisition in fostering reading literacy comprehension. These findings challenge the common perception that literacy is an organic impossibility for people defined as intellectually disabled. Moreover, the results add to recent research in sociocognitive instruction that supports the need to modify prevailing methods of reading curriculum and suggests a reconceptualisation of the comprehension process and its instruction to students with intellectual disabilities.     

Instructional Efficiency of Performance Analysis Training for Learners at Different Levels of Competency in Using a Web‐Based EPSS

ABSTRACT The measure of performance improvement potential (Gilbert, 1978) in human performance technology uses an exemplary performance as a criterion against which to measure the potential improvement in the performance of a workforce. The measure is calculated based on the performance efficiency which compares expended resources to productivity. The same notion is used to measure the efficiency of instructional conditions, based on learners' mental effort invested in a learning task compared to their performance. This article compares the efficiency of an instructional condition for three groups of students differentiated by their use of an electronic performance support system (EPSS) to conduct a performance analysis project. The results indicated that the instruction was most efficient for those learners who showed greater competency in using the EPSS. Implications for using this technique as a means of formative evaluation of a course are discussed.     

In-depth analysis of handwriting curriculum and instruction in four kindergarten classrooms

The quality of handwriting curriculum and instructional practices in actual classrooms was investigated in an in-depth case study of four inner city kindergarten classrooms using quantitative and qualitative methods. The handwriting proficiency of students was also evaluated to assess the impact of the instructional practices observed. The findings suggest that even though teachers employ a number of effective strategies, there is room for improvement in implementing effective, research-approved handwriting instruction. In particular, daily, explicit instruction, writing for fluency, writing from memory, and use of self-evaluation are areas that need improvement. Results indicate that the lack of emphasis on these practices impacted the quality of teaching and learning of handwriting skills. Future research is needed on the impact of teacher training, use of an assessment tool that objectively assesses students’ handwriting, use of reading and handwriting curriculum that complement and reinforce one another, and the effectiveness of research-based strategies in practice.     

The effect of different chunking strategies in complementing animated instruction

The purpose of this exploratory and small‐scale study was to examine the instructional effects of different chunking strategies used to complement animated instruction in terms of facilitating achievement of higher order learning objectives. Eighty‐five students were randomly assigned to three treatment groups: animated program instruction, simple visual‐text (static images and verbal explanation) chunked animated program instruction and the animated complex visual‐text chunked program instruction. The difference between simple and complex chunked instructions is the content. Simple chunks only deal with one content area while the complex chunks explain two or more related content areas. Students interacted with their respective web‐based instructional treatments and completed four criterion measures. Results (ANOVA) indicated that significant differences in achievement were found to exist in facilitating higher order learning objectives when chunking strategies were specifically designed and positioned to complement the animated instruction. Results also indicated that complex chunking is more effective in reducing the cognitive load present in an animated instructional environment, and that students need prerequisite knowledge before being able to profit from animated instruction designed to facilitate higher order learning outcomes.     

Integration of computers and related technologies into deaf education teacher preparation programs

The study examined how computer technology is used, modeled, and taught in programs that prepare future teachers of students who are deaf or hard of hearing. Data were collected through two self-reported survey instruments sent to participants from two different groups: (a) deaf education faculty (n = 233) and (b) administrators of programs serving students who are deaf or hard of hearing (n = 100). Among the faculty who responded to the survey, 99% said they used computers and printers for instruction during class, 84% said they used VCRs for instruction during class, and 56% said they used video cameras for instruction during class. The information that was reported on how technology was being used for instruction and how its use was being taught to students in deaf education teacher preparation programs indicates that the need persists for integration of technology into these programs. A need likewise continues for improved instructional strategies relative to computers and technology.     

Some Effects of Promotion and Non-Promotion upon the Social and Personal Adjustment of Children

Past research on cognition has demonstrated that cognitive learning strategies used to complement instruction can have beneficial effects on memory and subsequent achievement. The utilization of microcomputer technology to deliver instructional content to students provides an optimum environment to examine the instructional effectiveness of embedded instructional strategies. The purpose of this study was to examine the effect of an imagery cue and an attention directing strategy within a context of a microcomputer learning environment that provided both self-paced and externally paced instruction. Achievement was measured on five different tests designed to measure different educational objectives. One hundred eighty freshman students were randomly assigned to one of nine treatment groups. The results of the study indicate that embedding an imagery cue and an attention directing strategy in an instructional sequence increases student achievement. A combination of the two embedded strategies was also effective in improving students’ achievement; however, the combining of the two strategies did not have a cumulative effect. It was also determined that the effectiveness of the embedded strategies was dependent on whether the instruction was self-paced or externally paced.     

Early Comprehension Instruction for Spanish‐Speaking English Language Learners: Teaching Text‐Level Reading Skills While Maintaining Effects on Word‐Level Skills

This study investigated the effects of three instructional conditions on precursors to successful reading for Spanish‐speaking English language learners (ELL). The study was conducted using a randomized, alternate treatment control group design specifically targeting phonological awareness (PA) listening comprehension (LC), and decoding in a sample of ELL (N= 82) including students who were and were not at risk for later reading failure. Two randomly assigned experimental intervention groups and one treatment control group were created to test the effectiveness of three instructional interventions that differed in the relative amount of time used for instructing the word‐ and text‐level targeted skills. Specifically, the two experimental intervention groups received different doses of LC relative to PA instruction, creating a LC Concentration group and a PA Concentration group. The treatment control group received only PA and alphabet knowledge instruction (word‐level skills). Results indicated that both at‐risk and not‐at‐risk ELLs in the LC Concentration group outperformed students in the other groups on almost all measures, including PA skills, despite minimal amounts of instructional time‐targeting word‐level skills. These data extend the existing literature by lending empirical support to the use of a LC component in early reading interventions for young ELL.     

The relationship between strategic reading instruction,student learning of L2‐based reading strategies and L2 reading achievement

This study investigates the relationship between strategic reading instruction, the process of learning second language‐based reading strategies and English reading achievement for Thai university students of science and technology. In a course in reading general English texts for 16 weeks, 82 students were taught using a strategies‐based approach (experimental cohort), whereas another 82 students were taught using a traditional, teacher‐centred approach (control cohort). A pre‐test/post‐test research design was employed, and a portfolio approach was used to investigate the experimental cohort students' process of learning reading strategies. The results showed that the experimental cohort outperformed the control cohort in the post‐course standardised English test. The higher‐level reading proficiency learners in the experimental cohort were also found to be better than their low‐level peers at learning to use second language‐based reading strategies effectively. Implications are discussed for alternative instructional practice of reading in English as a foreign language (EFL).     

Effect of cooperative learning strategies on student verbal interactions and achievement during conceptual change instruction in 10th grade general science

This study evaluated the effects of cooperative learning on students' verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. Current conceptual change instructional models recognize the importance of student–student verbal interactions, but lack specific strategies to encourage these interactions. Cooperative learning may provide the necessary strategies. Two sections of low-ability 10th-grade students were designated the experimental and control groups. Students in both sections received identical content instruction on the particle model of matter using conceptual change teaching strategies. Students worked in teacher-assigned small groups on in-class assignments. The experimental section used cooperative learning strategies involving instruction in collaborative skills and group evaluation of assignments. The control section received no collaborative skills training and students were evaluated individually on group work. Gains on achievement were assessed using pre- and posttreatment administrations of an investigator-designed short-answer essay test. The assessment strategies used in this study represent an attempt to measure conceptual change. Achievement was related to students' ability to correctly use appropriate scientific explanations of events and phenomena and to discard use of naive conceptions. Verbal interaction patterns of students working in groups were recorded on videotape and analyzed using an investigator-designed verbal interaction scheme. The targeted verbalizations used in the interaction scheme were derived from the social learning theories of Piaget and Vygotsky. It was found that students using cooperative learning strategies showed greater achievement gains as defined above and made greater use of specific verbal patterns believed to be related to increased learning. The results of the study demonstrated that cooperative learning strategies enhance conceptual change instruction. More research is needed to identify the specific variables mediating the effects of cooperative learning strategies on conceptual change learning. The methods employed in this study may provide some of the tools for this research.     

Statement-Pie: a strategy to improve the paragraph writing skills of adolescents with learning disabilities

This study investigated the effects of teaching a metacognitive text structure strategy upon the paragraph writing skills of eighth-grade students with learning disabilities. The technique, called Statement-Pie (Hanau, 1974), teaches students to understand the relationship of supporting details to a main idea. Four students were taught to use an outline as a paragraph planning guide, which they then used to convert information into written expository paragraphs. All subjects reached instructional outcome criterion on the writing of comparison/contrast and sequence paragraphs. One week after reaching mastery in the special education classroom, students generalized their paragraph writing skills to other teachers and to different classrooms. The results of this investigation indicate that when provided with direct, intensive instruction in a text structure strategy, adolescents with learning disabilities can improve their skills in paragraph writing.     

Instructional approaches to foster third graders’ adaptive use of strategies: an experimental study on the effects of two learning environments on multi-digit addition and subtraction

The adaptive use of strategies, that is selecting a strategy which allows an efficient solution for a given problem, can be considered as an important individual ability relevant in various domains. Based on models of subjects’ skills of adaptive use of strategies, two idealized instructional approaches are suggested to foster students in their strategy development. The explicit approach aims at reducing cognitive load by demonstrating and practicing strategies combined with an explicit identification of criteria for strategy efficiency by contrasting problem solutions. The implicit approach capitalizes on the generation effect and stimulates students to generate their own strategies and efficiency criteria based on the analysis of task characteristics and the comparison of problem solutions. In a 1-week experimental study (16 lessons) with 73 third-graders, we examined the effectiveness of these instructional approaches in the domain of multi-digit addition and subtraction. Results from post- and two follow-up tests after 3 and 8?months did not yield different effects of the two approaches on students’ skills in adaptive use of strategies. A comparison of strategies used by the students showed that the students of the explicit approach more frequently applied complex strategies whereas the students from the implicit approach showed a more sustainable use of self-generated strategies. Hence, for the adaptive use of those strategies students are able to generate, the implicit approach turned out to be more effective than the explicit approach. However, this generation effect does not hold for strategies which are too complex to be generated by students.     

Teaching Students with Emotional and Behavioral Disorders to Self-advocate through Persuasive Writing

We examined the effectiveness of the Self-Regulated Strategy Development (SRSD) model of writing instruction with a self-determination training component for middle school-age students with emotional and behavioral disorders. We randomly assigned students to experimental or comparison treatments during which special education teachers provided the intervention. Students in the experimental groups received instruction on how to plan and write persuasive essays, were trained on self-determination skills, and were taught how to use persuasive writing to self-advocate. Students in the comparison condition received writing instruction with the established school writing curriculum. Instruction for both groups lasted 33 days, four days a week during 30-minute sessions. Experimental students significantly outperformed comparison students at posttest in all the persuasive essay-writing components assessed, in their ability to recall the parts of a persuasive essay, in the self-efficacy measure, and on self-determination knowledge. Experimental students were able to maintain gains in almost all writing measures and were able to generalize to content areas, although comparison students slightly increased in number of words. Student and teacher interviews revealed an overall satisfaction with SRSD procedures and the results.
