A Theory-Driven Model of Community College Student Engagement

This mixed-methods study develops, operationalizes, and tests a new conceptual model of community college student engagement. Themes emerging from participant observations and semistructured interviews with 30 adult students enrolled at a Large Best Practices Community College (LBPCC) over the 2005–2006 academic year are used to guide selection of Self-Determination Theory (Deci & Ryan, 1985 Deci , E. L. & Ryan , R. M. ( 1985 ). Intrinsic motivation and self-direction behavior . New York : Plenum .[Crossref] , [Google Scholar], 2000 Deci , E. L. & Ryan , R. M. ( 2000 ). Intrinsic and extrinsic motivations: Classic definitions and new directions . Contemporary Educational Psychology , 25 , 54 – 67 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], 2002 Deci , E. L. & Ryan , R. M. ( 2002 ). Handbook of self-determination research . Rochester , NY : University of Rochester . [Google Scholar]) to frame the new conceptual model. Structural equation modeling techniques confirm that variables and relationships proposed by the new model represent a good fit with data from over 1,000 students surveyed in the Community College Survey of Student Engagement. Findings from this study suggest that community college engagement and related outcomes can be fostered by tuning campus policies, practices, and climates to promote students' senses of belonging, competence, and autonomy.     

Age Differences in Adaptive Decision Making: The Role of Numeracy

The primary purposes of the present study were to examine age differences in adaptive decision making and to evaluate the role of numeracy in mediating the relationship between age and adaptive decision making. Adaptive decision making was assessed by the Cups task (Levin, Weller, Pederson, & Harshman, 2007 Levin , I. P. , Weller , J. A. , Pederson , A. A. , & Harshman , L. A. ( 2007 ). Age-related differences in adaptive decision making: Sensitivity to expect value in risky choice . Judgement and Decision Making , 2 ( 4 ), 225 – 233 .[Web of Science ®] , [Google Scholar]). Forty-six younger (18 to 24 years old) and 37 older adults (61 to 89 years old) completed the Cups task. In addition, the Numeracy Scale (Lipkus, Samsa, & Rimer, 2001 Lipkus , I. M ., Samsa , G. , & Rimer , B. K. ( 2001 ). General performance on a numeracy scale among highly educated samples . Medical Decision Making , 21 ( 1 ), 37 – 44 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) was used to measure individual numeric ability. Adaptive decision making was operationalized by the Expected Value sensitivity (i.e., the product of probability and outcome magnitudes) across the gain and the loss domains. Older adults had significantly lower Expected Value sensitivity than young adults. In addition, older adults demonstrated significantly lower numeracy than younger adults. Finally, numeracy partially mediated the relationship between age and adaptive decision making. It is suggested that older adults’ declined decision making may be partially due to their declined numeric abilities. Implications were discussed in numeracy education and public policies concerning older adults.     

Memory Aging Knowledge and Memory Self-Appraisal in Younger and Older Adults

The purpose of this study was to examine relationships among memory aging knowledge and memory self-appraisal in college students and community-dwelling older adults. Participants completed the Knowledge of Memory Aging Questionnaire ([KMAQ] Cherry, Brigman, Hawley, & Reese, 2003 Cherry , K. E. , Brigman , S. , Hawley , K. S. , & Reese , C. M. ( 2003 ). The knowledge of memory aging questionnaire: Effects of adding a ‘don't know’ response option . Educational Gerontology , 29 , 427 – 446 . doi: 10.1080/713844360 [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) and the Memory Functioning Questionnaire ([MFQ] Gilewski, Zelinski, & Schaie, 1990 Gilewski , M. J. , Zelinski , E. M. , & Schaie , K. ( 1990 ). The memory functioning questionnaire for assessment of memory complaints in adulthood and old age . Psychology and Aging , 5 , 482 – 490 . doi: 10.1037/0882-7974.5.4.482 [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We hypothesized that poorer performance on the KMAQ stereotype scale, suggesting an ageist response bias, would be associated with more negative self-appraisals of memory. Results confirmed that responses on the KMAQ stereotype scale were significantly associated with responses on the MFQ Frequency of Forgetting scale and two shorter scales derived from the full MFQ, the memory self-efficacy scale (Zelinski & Gilewski, 2004 Zelinski , E. M. , & Gilewski , M. J. ( 2004 ). A 10-item Rasch modeled memory self-efficacy scale . Aging & Mental Health , 8 , 293 – 306 . doi: 10.1080/13607860410001709665 [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), and a revised Seriousness of Forgetting scale after controlling for age and educational level. Implications of these findings for the development of instructional materials to improve memory aging knowledge and memory self-appraisal in adulthood are discussed.     

Comment on “The Impact of Online Assessment on Grades in Community College Distance Education Mathematics Courses” by Ronald W. Yates and Brian Beaudrie

Abstract

This article comments on an earlier article by professors Yates and Beaudrie (2009 Yates, R. W. and Beaudrie, B. 2009. The impact of online assessment on grades in community college distance education mathematics courses. The American Journal of Distance Education, 23(2): 62–70. [Taylor & Francis Online] , [Google Scholar])who examined whether online assessment facilitates student cheating and found no evidence of such a greater prevalence of cheating. Professors Yates and Beaudrie are commended for their contribution to this increasingly important area of research. The analysis indicates that professor Yates and Beaudrie's (2009 Yates, R. W. and Beaudrie, B. 2009. The impact of online assessment on grades in community college distance education mathematics courses. The American Journal of Distance Education, 23(2): 62–70. [Taylor & Francis Online] , [Google Scholar]) conclusion may have been influenced by (1) a failure to adequately account for student ability, leading to potential selection bias; (2) their use of course grades, rather than exam grades as the key measure of student performance; (3) possible differences in precautions that instructors may have deployed in the unproctored sections in order to discourage cheating; and (4) the evolution of distance learning resources and methods over their long period of study.     

Identifying Possible Sources of Differential Functioning Using Differential Bundle Functioning With Polytomously Scored Data

Oshima, Raju, Flowers, and Slinde (1998) Oshima, T. C., Raju, N. S., Flowers, C. P. and Slinde, J. A. 1998. Differential bundle functioning using the DFIT framework: Procedures for identifying possible sources of differential functioning. Applied Measurement in Education, 11: 353–369. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] described procedures for identifying sources of differential functioning for dichotomous data using differential bundle functioning (DBF) derived from the differential functioning of items and test (DFIT) framework (Raju, van der Linden, & Fleer, 1995 Raju, N. S., van der Linden, W. J. and Fleer, P. F. 1995. IRT-based internal measures of differential functioning of items and tests. Applied Psychological Measurement, 19: 353–368. [Crossref], [Web of Science ®] , [Google Scholar]). The purpose of this study was to extend the procedures for dichotomous DBF to the polytomous case and to illustrate how DBF analysis can be conducted with polytomous scoring, common to psychological and educational rating scales. The data set used was parent and teacher ratings of child problem behaviors. Three group contrasts (teacher vs. parent, boy vs. girl, and random groups) and two bundle organizing principles (subscale designation and random selection) were used for the DBF analysis. Interpretations of bundle indexes in the context of child problem behaviors were presented.     

Benefits of Systematic Phonics Instruction

Systematic-phonics instruction appears to be more effective than nonsystematic phonics instruction for teaching reading (Ehri, Nunes, Stahl, & Willows, 2001 Ehri, L. C., Nunes, S. R., Stahl, S. A. and Willows, D. M. 2001. Systematic phonics instruction helps students learn to read: Evidence from the National Reading Panels meta-analysis.. Review of Educational Research, 71: 393–447. [Crossref], [Web of Science ®] , [Google Scholar]). In the present study, a systematic phonics approach was directly compared with a nonsystematic phonics approach for kindergarten children. Both approaches were delivered using computer programs teaching the same Dutch grapheme–phoneme correspondences. Both phonics-trained groups progressed to the same extent on productive letter-sound knowledge compared to the control group. However, on measures of phonemic awareness, spelling, and reading, the systematic phonics group made more progress than the nonsystematic phonics group and the control group.     

Analysis of Parent,Teacher, and Consultant Speech Exchanges and Educational Outcomes of Students With Autism During COMPASS Consultation

The significant increase in the numbers of students with autism combined with the need for better trained teachers (National Research Council, 2001) call for research on the effectiveness of alternative methods, such as consultation, that have the potential to improve service delivery. Data from 2 randomized controlled single-blind trials indicate that an autism-specific consultation planning framework known as the collaborative model for promoting competence and success (COMPASS) is effective in increasing child Individual Education Programs (IEP) outcomes (Ruble, Dalrymple, & McGrew, 2010 Ruble, L. A., Dalrymple, N. J. and McGrew, J. H. 2010. The effects of consultation on Individualized Education Program outcomes for young children with autism: The collaborative model for promoting competence and success. Journal of Early Intervention, 32: 286–301. doi:10.1177/1053815110382973[Crossref], [PubMed] , [Google Scholar]; Ruble, McGrew, & Toland, 2011 Ruble, L., McGrew, J. and Toland, M. Randomized controlled study of teacher training in autism. Poster session presented at the meeting of the American Psychological Association. Washington, DC. August.  [Google Scholar]). In this study, we describe the verbal interactions, defined as speech acts and speech act exchanges that take place during COMPASS consultation, and examine the associations between speech exchanges and child outcomes. We applied the Psychosocial Processes Coding Scheme (Leaper, 1991 Leaper, C. 1991. Influence and involvement in children's discourse: Age, gender, and partner effects. Child Development, 62: 797–811. doi:10.1111/j.1467-8624.1991.tb01570.x[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) to code speech acts. Speech act exchanges were overwhelmingly affiliative, failed to show statistically significant relationships with child IEP outcomes and teacher adherence, but did correlate positively with IEP quality.     

Reporting Monte Carlo Studies in Structural Equation Modeling

In structural equation modeling, Monte Carlo simulations have been used increasingly over the last two decades, as an inventory from the journal Structural Equation Modeling illustrates. Reaching out to a broad audience, this article provides guidelines for reporting Monte Carlo studies in that field. The framework of discourse is set by a number of steps to be taken in such research, matching outlines of experimental design by Paxton, Curran, Bollen, Kirby, and Chen (2001) Chen, F., Bollen, K. A., Paxton, P., Curran, P. J. and Kirby, J. 2001. Improper solutions in structural equation modeling: Causes, consequences, and strategies. Sociological Methods & Research, 29: 468–508. [Crossref], [Web of Science ®] , [Google Scholar] and Skrondal (2000) Skrondal, A. 2000. Design and analysis of Monte Carlo experiments: Attacking the conventional wisdom. Multivariate Behavioral Research, 35: 137–167. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. Throughout the article, reference is made to exemplary publications and, occasionally, to imperfect reporting.     

Environmental Problems,Causes, and Solutions: An Open Question

In a national evaluation of environmental literacy in Israel, (Negev, Sagy, Garb, Salzberg, & Tal, 2008 Negev, M., Sagy, G., Garb, Y., Salzberg, A. and Tal, A. 2008. Evaluating the environmental literacy of Israeli elementary and high school students. Journal of Environmental Education, 39(2): 3–20. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), the authors included both multiple choice questions and open questions. In this article the authors describe the qualitative analysis of the answers to an open question regarding a local environmental problem. Most participants specified solid waste, open spaces, or air pollution as the main issues. The perceived solutions were generally at the governmental level, including planning, infrastructure, legislation, and enforcement. The authors describe relations in these responses between the problems, their causes and solutions, and between the quality of these answers and the general environmental literacy of the participants. The authors end with a discussion of the special contributions and potential of open-ended questions for environmental education research.     

The Devil is in the Detail Regarding the Efficacy of Reading Recovery: A rejoinder to Schwartz,Hobsbaum, Briggs,and Scull

This rejoinder provides comment on issues raised by Schwartz, Hobsbaum, Briggs and Scull (2009 Schwartz, R. M., Hobsbaum, A., Briggs, C. and Scull, J. 2009. Reading Recovery and evidence‐based practice: A response to Reynolds and Wheldall (2007). International Journal of Disability, Development and Education, 56(1): 5–15. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) in their article about evidence‐based practice and Reading Recovery (RR), written in response to Reynolds and Wheldall (2007 Reynolds, M. and Wheldall, K. 2007. Reading Recovery twenty years down the track: Looking forward, looking back. International Journal of Disability, Development and Education, 54: 199–223. [Taylor & Francis Online] [Google Scholar]). Particular attention is paid to the processes and findings of the What Works Clearinghouse evaluation of RR. The suggestion that this evaluation is flawed casts doubt about some of its findings. The authors maintain their earlier stance that RR is effective for many students but do not accept that there is evidence that initial gains are sustained through the primary grades, that RR is an efficient tier two intervention in a response to intervention approach and that significant cost benefits have been demonstrated in education systems. It is concluded that research into alternative interventions that could be implemented at lower cost is warranted.     

Conceptions of assessment: trainee teachers' practice and values

This study examines the values and practice in relation to assessment of a sample of 220 trainee teachers studying for a Postgraduate Certificate in Education, an initial teacher training and education (ITET) course, at the University of Cambridge, UK. The survey instrument was drawn from James and Pedder (2006 James, M. and Pedder, D. 2006. Beyond method: Assessment and learning practices and values. The Curriculum Journal, 17(2): 109–138. [Taylor & Francis Online] , [Google Scholar]), and was composed of questionnaire items that sought to elicit how trainees valued different classroom assessment practices, and the extent to which their own teaching complied with such values. The study draws additionally on the findings of James and Pedder (2006 James, M. and Pedder, D. 2006. Beyond method: Assessment and learning practices and values. The Curriculum Journal, 17(2): 109–138. [Taylor & Francis Online] , [Google Scholar]) to compare and contrast results with those for qualified teachers. Item and factor analyses revealed three dimensions that underpin trainees' classroom practice and values (promoting learning autonomy, performance orientation, making learning explicit). Values-practice gaps were greatest on promoting learning autonomy and performance orientation. Trainees valued practices associated with the former more than they implemented them in their teaching, while they implemented practices associated with the latter more than predicted by their values. Values-practice gaps suggested that trainees were constrained from implementing their values to a greater extent than qualified teachers, particularly with respect to these two factors.     

THREE STRATEGIES FOR DELIVERING CONTINUING MEDICAL EDUCATION IN GERIATRICS TO GENERAL PRACTITIONERS

General practitioners (GPs) need advanced skills in geriatric assessment to be competent to treat the increasing number of elderly patients. Continuing medical education in geriatrics for GPs is heterogeneous, and not assessed for effectiveness. In this study we compared the educational effects of three geriatric post-graduate training methods on GPs. GPs in the health district of the Nijmegen University Medical Centre (The Netherlands) were offered a variety of training options in geriatric assessment: (1) a formal one-day teacher centered conference (TCC), (2) an interactive GP-centered day of workshops (GCW), and (3) participation in a project of knowledge translation, linked to a research project of geriatric intermediate care (GKT). Pre-post measures were taken of the attitudes of GPs towards the elderly (Aging Semantic Differential, 1969), attitudes towards geriatric patients (Maxwell & Sullivan, 1980 Maxwell, A. J. and Sullivan, N. 1980. Attitudes toward the geriatric patient among family practice residents. Journal of the American Geriatric Society, 2(8): 341–345.  [Google Scholar]; Rosencranz & McNevin, 1969 Rosencranz, H. A. and McNevin, T. E. 1969. A factor analysis of attitudes towards the aged. Gerontologist, 9: 55–59. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and geriatric competencies (Robinson, Barry, Renick, et al., 2001 Robinson, B. E., Barry, P. P., Renick, N., Bergen, M. R. and Stratos, G. A. 2001. Physician confidence and interest in learning more about common geriatric topics: A needs assessment. Journal of the American Geriatric Society, 49: 963–967. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). After training, neither the attitudes towards the elderly nor geriatric patients changed in any of the three groups. The TCC did not show a significant change in perceived competencies, while the GCW and GKT group improved. A formal large group conference is ineffective in improving GPs' geriatric assessment skills, while small interactive workshops and participation in a project of knowledge translation are equally effective. None of the three training methods improved or worsened attitudes toward the elderly in general or the geriatric patients in particular.     

Equivalent Structural Equation Models: A Challenge and Responsibility

Relevant aspects of the example provided by Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142–149. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] are emphasized, specifically the distinctiveness of infinitely many members of its sequence of equivalent structural equation models. This emphasis appears to be needed in light of recent statements by Markus (2002) Markus, K. A. 2002. Statistical equivalence, semantic equivalence, eliminative induction and the Raykov–Marcoulides proof of infinite equivalence. Structural Equation Modeling, 9: 503–522. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], whose intended counterexamples do not present a disconfirmation of any of the developments of Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142–149. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. Issues pertaining to differentiation between equivalent models are also discussed.     

Comparison of Students' Knowledge Structure Coherence and Understanding of Force in the Philippines,Turkey, China,Mexico, and the United States

This study investigates the ongoing debate in the conceptual change literature between unitary and elemental perspectives on students' knowledge structure coherence. More specifically, the current study explores two potential explanations for the conflicting results reported by Ioannides and Vosniadou (2002 Ioannides, C. and Vosniadou, S. 2002. The changing meanings of force. Cognitive Science Quarterly, 2(1): 5–62.  [Google Scholar])and diSessa, Gillespie, and Esterly (2004 diSessa, A. A, Gillespie, N. and Esterly, J. 2004. Coherence versus fragmentation in the development of the concept of force. Cognitive Science, 28: 843–900. [Crossref], [Web of Science ®] , [Google Scholar]) in terms of differences in coding schemes and differences in student populations. The current study addresses these questions by applying the coding schemes from both studies to interviews with 201 students drawn from the United States, the Philippines, Turkey, China, and Mexico. The analyses focus first on the coding schemes, suggesting that differences in coding schemes seem unlikely to account for the differences in the original studies. The analyses then focus on potential differences between student populations, suggesting that some differences exist in terms of consistency and meanings that might result from language, culture, or educational systems, but that these differences are too small to account for the radical differences in the findings of the original studies. Two additional explanations are then proposed and explored involving the instruments and the epistemological stances invoked for the students. Overall, the results align more closely with the findings of diSessa, Gillespie, and Esterly (2004 diSessa, A. A, Gillespie, N. and Esterly, J. 2004. Coherence versus fragmentation in the development of the concept of force. Cognitive Science, 28: 843–900. [Crossref], [Web of Science ®] , [Google Scholar]).

Structural Equation Models of Latent Interactions: Clarification of Orthogonalizing and Double-Mean-Centering Strategies

The purpose of this investigation is to compare a new (double-mean-centering) strategy to estimating latent interactions in structural equation models with the (single) mean-centering strategy (Marsh, Wen, & Hau, 2004 Marsh, H. W., Wen, Z. and Hau, K. T. 2004. Structural equation models of latent interactions: Evaluation of alternative estimation strategies and indicator construction.. Psychological Methods, 9: 275–300. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2006 Marsh, H. W., Wen, Z. and Hau, K. T. 2006. “Structural equation models of latent interaction and quadratic effects”. In A second course in structural equation modeling Edited by: Hancock, G. and Mueller, R. 225–265. Greenwich, CT: Information Age.  [Google Scholar]) and the orthogonalizing strategy (Little, Bovaird, & Widaman, 2006 Little, T. D., Bovaird, J. A. and Widaman, K. F. 2006. On the merits of orthogonalizing powered and product term: Implications for modeling interactions among latent variables.. Structural Equation Modeling, 13: 497–519. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; Marsh et al., 2007 Marsh, H. W., Wen, Z., Hau, K. T., Little, T. D., Bovaird, J. A. and Widaman, K. F. 2007. Unconstrained structural equation models of latent interactions: Contrasting residual- and mean-centered approaches.. Structural Equation Modeling, 14: 570–580. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). A key benefit of the orthogonalizing strategy is that it eliminated the need to estimate a mean structure as required by the mean-centering strategy, but required a potentially cumbersome 2-step estimation procedure. In contrast, the double-mean-centering strategy eliminates both the need for the mean structure and the cumbersome 2-stage estimation procedure. Furthermore, although the orthogonalizing and double-mean-centering strategies are equivalent when all indicators are normally distributed, the double-mean-centering strategy is superior when this normality assumption is violated. In summary, we recommend that applied researchers wanting to estimate latent interaction effects use the double-mean-centering strategy instead of either the single-mean-centering or orthogonalizing strategies, thus allowing them to ignore the cumbersome mean structure.     

Informing Design Research: Learning From Teachers' Designs of Social Infrastructure

The design research methodology as it has currently developed centers on the creation of existence proofs, an important first step. What is needed then are the next steps of expanding the methodology to address the design problems of practical implementation prior to the steps involved in scaling up these designs. This article contributes to such an expansion through developing a systematic approach to learning from teachers' enactments of educational models. Design research focused on practical implementations by teachers can create knowledge regarding critical change processes, thus helping to create a theory of trajectories of change, or “implementation paths” (Bielaczyc & Collins, 2006a Bielaczyc, K. and Collins, A. 2006a. Implementation paths: Supporting the trajectory teachers traverse in implementing technology-based learning environments in classroom practice. Journal of Educational Technology, 46(2): 8–14.  [Google Scholar] Collins, Joseph, & Bielaczyc, 2004 Collins, A., Joseph, D. and Bielaczyc, K. 2004. Design research: Theoretical and methodological issues. Journal of the Learning Sciences, 13: 15–42. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Here I propose using the Social Infrastructure Framework (Bielaczyc, 2006 Bielaczyc, K. 2006. Designing social infrastructure: Critical issues in creating learning environments with technology. Journal of the Learning Sciences, 15: 301–329. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) to analyze the design of classroom social structures by developers and teachers in order to better understand their implications for constructing implementation paths. The analytic technique is exemplified through a case study involving a particular team of teachers who worked over the course of several years to adopt a knowledge-building communities approach (Bereiter, 2002 Bereiter, C. 2002. Education and mind in the knowledge age, Mahwah, NJ: Erlbaum. [Crossref] , [Google Scholar]; Scardamalia, 2002 Scardamalia, M. 2002. “Collective cognitive responsibility for the advancement of knowledge”. In Liberal education in the knowledge society, Edited by: Smith, B. 67–98. Chicago, IL: Open Court.  [Google Scholar]; Scardamalia & Bereiter, 1991 Scardamalia, M. and Bereiter, C. 1991. Higher levels of agency for children in knowledge building: A challenge for the design of new knowledge media. Journal of the Learning Sciences, 1: 37–68. [Taylor & Francis Online] , [Google Scholar] 1994). The results are used to discuss implications for the methodology of design research.     

Multistage Computerized Adaptive Testing With Uniform Item Exposure

This article describes a computerized adaptive test (CAT) based on the uniform item exposure multi-form structure (uMFS). The uMFS is a specialization of the multi-form structure (MFS) idea described by Armstrong, Jones, Berliner, and Pashley (1998 Armstrong, R. D., Jones, D. H., Berliner, N. and Pashley, P. June 1998. Computerized adaptive tests with multiple form structures, June, Champaign-Urbana, IL: Paper presented at the annual meeting of the Psychometric Society.  [Google Scholar]). In an MFS CAT, the examinee first responds to a small fixed block of items. The items comprising that block may be unrelated to each other, or they may comprise a testlet (Wainer and Kiely, 1987 Wainer, H. and Kiely, G. L. 1987. Item clusters and computerized adaptive testing: A case for testlets. Journal of Educational Measurement, 24: 185–201. [Crossref], [Web of Science ®] , [Google Scholar]) After the first block of items has been administered, adaptation takes place in the choice of the next block to be administered and subsequent blocks. The uMFS design integrates item exposure control, as well as content balancing and other test development needs, into the design of the CAT, instead of placing those activities in the online implementation. We show that it is possible to implement item exposure control, in a very thorough way, in the psychometric specifications of the item blocks.     

The Growth of Phonological Awareness by Children With Reading Disabilities: A Result of Semantic Knowledge or Knowledge of Grapheme-Phoneme Correspondences?

According to the Lexical Restructuring Model (Metsala & Walley, 1998 Metsala, J. L. and Walley, A. C. 1998. “Spoken vocabulary growth and the segmental restructuring of lexical representation: Precursors to phonemic awareness and early reading ability”. In Word recognition in beginning literacy, Edited by: Metsala, J. L. and Ehri, L. C. 89–120. Mahwah, NJ: Lawrence Erlbaum Associates, Inc.  [Google Scholar]), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) Ziegler, J. C. and Goswami, U. 2005. Reading acquisition, developmental dyslexia, and skilled reading across languages: A psycholinguistic grain size theory.. Psychological Bulletin, 131: 3–29. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness.
