Analysing the correlation between secondary mathematics curriculum change and trends in beginning undergraduates’ performance of basic mathematical skills in Ireland

The phenomenon in which students enter university under-prepared for the mathematical demands of their undergraduate courses, regularly referred to as the ‘Maths Problem’, has been widely reported in Ireland, UK, Australia, and the US. This issue has been of particular concern in Ireland recently, with beginning undergraduates’ performance of basic mathematical skills showing signs of significant decline in recent years. New mathematics curricula, commonly referred to as ‘Project Maths’, were gradually introduced into the Irish secondary school education system from 2010 onwards. These new curricula aim to place greater emphasis on student understanding of mathematical concepts, use of contexts, and applications of mathematics. This study analyses, through mathematics diagnostic test data gathered between 2008 and 2014, the change in the basic mathematical skills of beginning undergraduates over the time period in which the new mathematics curricula were introduced to secondary education in Ireland. It was found that students’ basic mathematical skills have declined over the time period during which the new mathematics curricula were introduced. Significant declines in beginning undergraduates’ performance of basic mathematical skills were observed during the period 2008–2014, particularly among students who have achieved Higher Level C grades and Higher Level D grades.     

Comparative Evaluations of Early Intervention Alternatives: A Response to Commentaries by Guralnick and Telzrow

This article responds to two commentaries by Guralnick (1993) and Telzrow (1993) published in the October 1993 issue of Early Education and Development. The commentaries addressed the six longitudinal, comparative studies from the Early Intervention Research Institute's (EIRI's) investigations of the effects and costs of early intervention for children with disabilities. In this response to their thoughtful critique, we clarify details of our research design and procedures that may have been unclear. We also discuss the specificity and consistency with contemporary developmental/ecological issues raised by Guralnick We contend that the interventions investigated address important questions about age at start, intensity, and parent involvement with which today's service providers contend. We give our opinion on how the results of these studies should be interpreted, and emphasize their implications for other second-generation early intervention research.     

Sharing Books and Learning Language: What do Latina Mothers and Their Young Children Do?

This study examined low-income, Spanish-speaking, immigrant Latina mothers' book sharing behaviors in relation to their children's vocabulary. Participants were 47 3-year-old children and their mothers. We addressed two research questions: (a) What interactive behaviors are evident when low-income immigrant Latina mothers and their 3-year-old children look at books together? (b) For these children and their mothers, which book-sharing behaviors are related to children's expressive language? Overall, our results indicated that mothers were involved in several kinds of interactions with the books. They enhanced their children's attention to the printed text, promoted interaction or conversation with their children about what was in the books, and somewhat less often, used more complex literacy strategies. Mothers who did these things most had children with the largest vocabularies even when mothers' vocabulary was taken into account. Implications for designing interventions for similar families are discussed.     

Stigmatised learners: mature-age students negotiating university culture

Research on the socially-situated nature of learning shows how practices and identities are affected by participation in communities, but very little is known about how mature-age students experience the relational dynamics of university. Based on data from a qualitative study of first-year students, we consider written accounts by older learners to examine how they negotiate the culture of higher education. We found that mature-age students encounter a university culture dominated by younger students, who draw separating boundaries between the social and the academic and stigmatise older students because of their academic practices. Drawing on Lave and Wenger’s learning theory, we examine the way mature-age students negotiate the process of becoming legitimate members of the learning community, and the resistance they face in doing so. Knowing how mature-age students learn, and how to support them, depends on examining their negotiation of university culture, as well as their differing aspirations and needs.     

Effect of context and gender on application of Science Investigation Skills

Two parallel versions of a Test of Science Investigation Skills were developed to assess students' application of science investigation skills in biology and physics contexts. Repeated pilot testing and critical appraisal were used to ensure the validity of the tests and their equivalence. Both versions of the test were administered to 112 Year 10 science students. The results indicated a satisfactory level of test reliability, the test set in a physics context proved to be significantly more difficult than the test set in a biology context, and mean scores for male and female students were not significantly different. Specializations: science teacher education, development of problem-solving expertise, concept development and conceptual change, assessment of laboratory work. Specializations: Chemistry education, concept development and conceptual change, effective laboratory teaching.

Structured Constructs Models Based on Change‐Point Analysis

This study proposes a structured constructs model (SCM) to examine measurement in the context of a multidimensional learning progression (LP). The LP is assumed to have features that go beyond a typical multidimentional IRT model, in that there are hypothesized to be certain cross‐dimensional linkages that correspond to requirements between the levels of the different dimensions. The new model builds on multidimensional item response theory models and change‐point analysis to add cut‐score and discontinuity parameters that embody these substantive requirements. This modeling strategy allows us to place the examinees in the appropriate LP level and simultaneously to model the hypothesized requirement relations. Results from a simulation study indicate that the proposed change‐point SCM recovers the generating parameters well. When the hypothesized requirement relations are ignored, the model fit tends to become worse, and the model parameters appear to be more biased. Moreover, the proposed model can be used to find validity evidence to support or disprove initial theoretical hypothesized links in the LP through empirical data. We illustrate the technique with data from an assessment system designed to measure student progress in a middle‐school statistics and modeling curriculum.
