An examination of self-directed contract learning as an instructional strategy

In recent years, instructors, academic programs, and innovative educational institutions have begun utilizing self-directed learning concepts and contract learning structures for assumed development of student self-directed learning outcomes. However, prior investigations of development of self-directed learning have been hortative in form or have examined correlative relationships of self-directed behavior with specific learner characteristics. Does learner participation in a self-directed contract learning course influence his/her future behavior and attitudes toward self-directed learning? This study examined the impact of a self-directed contract learning course upon participant self-directed learning behavior and attitudes. Findings of this study were examined from three forms of impact evaluation. Significant positive gains were noted on participant pre- and postgain scores on the Self-Directed Learning Readiness Scale (SDLRS). Course evaluations noted a majority of positive participant responses regarding perceived changes in knowledge and skill of self-directed learning as well as reported value of the course experience. The third form of impact evaluation came from observational diaries analysis. Diaries from selected students and the instructor were analyzed for major themes and transitions. A discussion of these themes and transition points are presented in a framework analysis of the Fuller and Bown “Concerns model.” Findings are discussed for their varying significance in understanding the development of self-directed learning behavior.     

Dilemmas of difference and the identification of special educational needs/disability: International perspectives

This article reports findings from an international study about dilemmas of difference in relation to special educational needs and disability in education. It was part of a larger study of the perspectives of 132 education practitioners and policy makers in England, the USA and the Netherlands to a range of dilemmas of difference. It also compares these current perspectives with ones from similar groups in England and the USA from the early 1990s. Participants were interviewed about their perspectives on a presented dilemma about the consequences of identifying children as having a disability or a special educational need. The data are presented in quantitative terms (degrees of recognition and resolution of dilemma) and qualitative terms (reasons, justifications and suggested resolutions). The findings show variations in responses to the dilemma that relate to national differences, but also commonalities in the recognition of this dilemma, reasons for recognising and ways of resolving the dilemma.     

Word learning in children: an examination of fast mapping

Children may be able to gain at least partial information about the meaning of a word from how it is used in a sentence, what words it is contrasted with, as well as other factors. This strategy, known as fast mapping, may allow the child to quickly hypothesize about the meaning of a word. It is not yet known whether this strategy is available to children in semantic domains other than color. In the first study, 2-, 3-, and 4-year-olds were introduced to a novel color, shape, or texture word by contrasting the new term with a well-known word from that domain. They were then tested for their ability to produce and comprehend the new term and for whether they knew what semantic domain the word referred to. The results show that even 2-year-old children can quickly narrow down the meaning of a word in each of the semantic domains examined, although children learned more about shape terms than color or texture words. A second study explored the effects of several variables on children's ability to infer the meaning of a new term. One finding of this study was that if the context is compelling, children can figure out the meaning of a new word even without hearing an explicit linguistic contrast.     

An examination of male-female performance in a programmed achievement learning center

College students operated under different classroom contingencies. The Programmed Achievement (PA) condition required students to evidence criterion performance (100% mastery) on weekly quizzes. Failure to show mastery performance on any of the weekly quizzes resulted in course failure. The Standard Control (S-C) condition involved a more traditional college classroom structure where students took weekly quizzes with no requirement to evidence mastery. Male and female performances were analyzed to determine if different course structures interacted with sex of student. The results indicated that PA students demonstrated higher performance than controls on weekly quizzes and a major exam. It was also shown that PA females increased at a more rapid rate than PA males, while S-C males and females were not significantly different. Theoretical implications of the results are discussed.

An experiment in learning algebra with an intelligent learning environment

This paper presents a new prototype of an intelligent learning environment and the results of an experiment in learning by problem solving. Forty-six French secondary school students solved problems of polynomial factorization by interacting with the learning environment during four forty-five-minute sessions. The intelligent learning environment is a new version of the APLUSIX system, called APLUSIX/M0-V2, that has been implemented on a Macintosh computer. This system checks the validity of the actions a student wants to perform, tells the student why a query is invalid, does the calculations for the student, and gives advice if asked for help. The objective of the learning experiment was to enable students to acquire (i) knowledge in matching formal rules of transformation with a given expression; and (ii) heuristics of choice between possible transformations. The results confirmed the existence of several different levels of matching knowledge as well as several different student learning paths in the acquisition of matching knowledge. Heuristics appeared to be fairly easily learned with the APLUSIX learning environment.     

Iterative learning control of SOFC based on ARX identification model

This paper presents an application of iterative learning control (ILC) technique to the voltage control of solid oxide fuel cell (SOFC) stack. To meet the demands of the control system design, an autoregressive model with exogenous input (ARX) is established. Firstly, by regulating the variation of the hydrogen flow rate proportional to that of the current, the fuel utilization of the SOFC is kept within its admissible range. Then, based on the ARX model, three kinds of ILC controllers, i.e. P-, PI- and PD-type are designed to keep the voltage at a desired level. Simulation results demonstrate the potential of the ARX model applied to the control of the SOFC, and prove the excellence of the ILC controllers for the voltage control of the SOFC.

Feasibility and consequences of response to intervention: examination of the issues and scientific evidence as a model for the identification of individuals with learning disabilities

This paper provides a response to the thoughtful paper presented by Gerber in this issue and at the National Research Center on Learning Disabilities Responsiveness-to-Intervention Symposium in Kansas City with guidance from five major questions posed by the organizers of the symposium. Gerber's paper provides interesting perspectives regarding the alternative approach to identification of learning disabilities (LD) or the "response to intervention" (RTI). Gerber raises questions and concerns about the theoretical and practical aspects of a response-to-intervention model on either a small- or large-scale basis. Guiding questions for this response include an examination of (a) changing roles of teachers and diagnosticians; (b) responsibility for fidelity of treatment implementation; (c) applications in secondary settings; (d) consistency of implementation from local to state to national levels; and (e) differentiation of LD from other disabilities. An alternative to both RTI and present procedures is proposed. Conclusions are discussed with respect to existing research-based evidence.     

A tool for analyzing implementation fidelity of an integrated learning system

One way to better understand the difficult instructional issues associated with the integration of computer technology in classrooms is to analyze the implementation of computer technology. This study developed and validated a measure for examining the quality of implementation of an Integrated Learning System (ILS). The measure was used to analyze ILS implementation and determine if there were differences in the operational patterns of teachers implementing an ILS and identify implementation practices of teachers that indicated implementation fidelity. The measure indicated which teachers were high fidelity implementers and which implementation practices distinguished high fidelity implementers.     

The influence of an NCLB accountability plan on the distribution of student test score gains

Previous research on the effect of accountability programs on the distribution of student test score gains is decidedly mixed. This study examines the issue by estimating an educational production function in which test score gains are a function of the incentives schools have to focus instruction on below-proficient students. NCLB's threat of sanctions are positively correlated with test score gains by below-proficient students in failing schools; greater than expected test score gains by below-proficient students do not occur at the expense of high-performing students in failing schools. This pattern of results tends to suggest that failing schools were able to benefit low-performing students in ways that were consistent with having operational slack, and that the threat of sanctions may stimulate greater productivity within failing schools.     

Role of cognitive theory in the study of learning disability in mathematics

Gersten, Jordan, and Flojo (in this issue) provide the beginnings of an essential bridge between basic research on mathematical disabilities (MD) in young children and the application of this research for the early identification and remediation of these forms of learning disability. As they acknowledge, the field of MD is in the early stages of development, and thus recommendations regarding identification measures and remedial techniques must be considered preliminary. I discuss the importance of maintaining a tight link between theoretical and empirical research on children's developing numerical, arithmetical, and mathematical competencies and future research on learning disabilities in mathematics. This link will provide the foundation for transforming experimental procedures into assessment measures, understanding the cognitive strengths and weaknesses of children with these forms of learning disability, and developing remedial approaches based on the pattern of cognitive strengths and weaknesses for individual children.     

Grasping the dynamic complexity of team learning: An integrative model for effective team learning in organisations

In this article we present an integrative model of team learning. Literature shows that effective team learning requires the establishment of a dialogical space amongst team members, in which communicative behaviours such as ‘sharing’, ‘co-construction’ and ‘constructive conflict’ are balanced. However, finding this balance is not enough. Important questions such as ‘communicating about what?’, ‘communicating with whom?’ and ‘communicating for what?’ remain crucial. Five other process variables ‘team reflexivity’, ‘team activity’, ‘boundary crossing’, ‘storage’ and ‘retrieval’ are identified. Besides the core process variables, our model organises the most important inputs, catalyst emergent states and outputs of team learning.     

An examination of the reading performance of students with mild educational handicaps or learning disabilities

Reading performance is a primary concern in both regular and special education. Reading is also the dominant medium through which educators conduct lessons, or students acquire information in subjects such as science and mathematics. Reading performance can be measured in a variety of ways. The present study examined the performance of students with mild educational handicaps (n = 28) or learning disabilities (n = 38) on a combination of norm-referenced and curriculum-based assessment (CBA) approaches that used science content. Overall, there were no significant differences between the samples on measures of word recognition, but significant differences favoring students with learning disabilities did occur in comprehension.     

An extension of the technology acceptance model for online learning environments

This study advances the understanding of the process by which students accept and use e-learning environments. This is a key aspect in studying the online behaviour of students, as it directly influences their conduct in their capacity as users of learning products. To address the lack of empirical data on the adoption of this type of learning environment, we present and validate a model of the phenomenon. The study considers the utilitarian aspects included in the technology acceptance model (TAM) and also an aspect of intrinsic motivation for an individual, flow, to enhancing the explanatory power of the models presented.

Based on a sample of 2,574 students, structural equation modelling is used to test the model. We identify the effect of flow on perceived ease of use, perceived usefulness and on the actual usage of the e-learning environment, demonstrating the importance of this factor as a complement to the components of the TAM.     

Prospects for the implementation of assessment for learning

This paper analyses aspects of a Hong Kong school curriculum reform, which recommends amongst other things, a greater focus on assessment for learning. It outlines the principles of the reform as it pertains to assessment and discusses how structural changes are being employed to lend support to changes in the assessment culture in Hong Kong. The paper draws on a previous problematic attempt to introduce formative assessment through the Target-Oriented Curriculum initiative. Two examples of assessment for learning practice of 'early adopters' are used to illustrate both the potential and some of the challenges of implementation in the Hong Kong primary school context. From these cases, are drawn out some of the facilitating and inhibiting factors impinging on the implementation of assessment for learning in schools, building on a model of professional growth.
