Puzzling with potential : dynamic testing of analogical reasoning in children

Assessment procedures are frequent in children's school careers; however, measuring potential for learning has remained a puzzle. Dynamic testing is a method to assess cognitive potential that includes training in the assessment process. The goal of this thesis project was to develop a new dynamic test of analogical reasoning for school children. The main aims were to (1) investigate factors that influence children’s differences in performance and change during dynamic testing and (2) examine the predictive value of dynamic measures on children’s school performance. Children showed great variation in cognitive potential. Higher ability children generally required less training and showed greater transfer to other problem sets. Yet, lower ability children tended to improve more during dynamic testing. Performance change during testing appears to be a unique predictor of math and reading achievement, but was unrelated to working memory or cultural background, providing evidence that this may be a separate construct important in the assessment of cognitive potential – especially in culturally diverse schools. This performance change measure, often criticized within classical test theory, has demonstrated its worth when estimated using item response theory models and will hopefully find its place again among the valuable measurement outcomes of children’s potential for learning.LEI Universiteit LeidenDevelopmental pathways of social-emotional and cognitive functioning - ou

Logistic Knowledge Tracing: A Constrained Framework for Learner Modeling

Adaptive learning technology solutions often use a learner model to trace learning and make pedagogical decisions. The present research introduces a formalized methodology for specifying learner models, Logistic Knowledge Tracing (LKT), that consolidates many extant learner modeling methods. The strength of LKT is the specification of a symbolic notation system for alternative logistic regression models that is powerful enough to specify many extant models in the literature and many new models. To demonstrate the generality of LKT, we fit 12 models, some variants of well-known models and some newly devised, to 6 learning technology datasets. The results indicated that no single learner model was best in all cases, further justifying a broad approach that considers multiple learner model features and the learning context. The models presented here avoid student-level fixed parameters to increase generalizability. We also introduce features to stand in for these intercepts. We argue that to be maximally applicable, a learner model needs to adapt to student differences, rather than needing to be pre-parameterized with the level of each student's ability

The role of cognitive flexibility in young children's potential for learning under dynamic testing conditions

The aim of the current study was to investigate to what extent children’s potential for learning is related to their level of cognitive flexibility. Potential for learning was measured through a dynamic testing procedure that aimed to measure how much a child can profit from a training procedure integrated into the testing process, including the amount and type of feedback the children required during this training procedure. The study followed a pre-test–training–post-test control group design. Participants were 153 6–7-year-old children. Half of this group of children were provided with a standardised graduated prompts procedure. The other half of the participants performed a non-inductive cognitive task. Children’s cognitive flexibility was measured through a card sorting test and a test of verbal fluency. Results show that cognitive flexibility was positively related to children’s performance, but only for children in the practice-only condition who received no training. These outcomes suggest that dynamic testing, and more in particular, the graduated prompting procedure, supports children’s cognitive flexibility, thereby giving children with weaker flexibility the opportunity to show more of their cognitive potential as measured through inductive reasoning.Pathways through Adolescenc

Connecting the Points: An Investigation into Student Learning about Decimal Numbers

The purpose of this research project was to investigate the effects of a short-term teaching experiment on the learning of decimal numbers by primary students. The literature describes this area of mathematics as highly problematic for students. The content first covered student understanding of decimal symbols, and how this impacted upon their ability to order decimal numbers and carry out additive operations. It was then extended to cover the density of number property, and the application of multiplicative operations to situations involving decimals. In doing so, three areas of cognitive conflict were encountered by students, the belief that longer decimal numbers are larger than shorter ones (irrespective of the actual digits), that multiplication always makes numbers bigger, and that division always makes numbers smaller. The use of a microgenetic approach yielded data was able to be presented that provides details of the environment surrounding the moments where new learning was constructed. The characteristics of this environment include the use of physical artifacts and situational contexts involving measurement that precipitate student discussion and reflection. The methodology allowed for the collection of evidence regarding the highly complex nature of the learning, with evidence of 'folding back' to earlier schema and the co-existence of competing schema. The discussion presents reasons as to why the pedagogical approach that was employed facilitated learning. One of the main findings was that the use of challenging problems situated in measurement contexts that involved direct student participation promoted the extension and/or re-organization of student schema with regard to decimal numbers. The study has important implications for teachers at the upper primary level wanting to support student learning about the decimal numbers system

Participating in a shared cognitive space: An exploration of working collaboratively and longer-term performance of a complex grammatical structure

Qatar’s education system has recently been subjected to a process of deep structural reform. One of the beliefs which underpins this reform is the assumption that learner-centred pedagogy is more effective than traditional teacher-centred pedagogy. However, there is limited empirical evidence from a Qatari classroom context regarding the effectiveness of using learner-centred pedagogies. This lack of empirical evidence extends to the teaching of English as a foreign language. This study employed Vygotskian sociocultural theory as a lens to investigate the effects of working collaboratively on learners’ longer-term performance of two grammatical structures, the simple past passive and the present continuous passive, as well as the cognitive processes involved. Interventionist dynamic assessment was used to quantify the linguistic performance of male Arabic undergraduate EFL learners (N = 52) three times (pretest, posttest, and delayed posttest) over a 12-week period. In-between the pretest and the posttest, six form-focused treatment tasks were administered. The experimental group (n = 20) completed the treatment tasks collaboratively; the comparison group (n = 16) completed the treatment tasks individually; and the control group (n = 16) did not complete the treatment tasks. In addition, the genetic method was employed to trace the linguistic development of four participants in the experimental group. These four participants were audio-recorded as they collaboratively completed each treatment session. Mood’s median test (Mood, 1954) found a pretest to posttest statistically significant difference (M = 7.70, df = 1, p = 0.01) between the performances of the experimental and control groups for the structure of the simple past passive which is moderate to large in size (Cramér’s V = 0.46). However for both target structures, no statistically significant difference was found between the experimental group and the comparison group, suggesting that the treatment condition of working collaboratively was not more effective in promoting learners’ linguistic development than the treatment condition of working individually. Additionally, the descriptive statistics revealed high levels of individual variation. Of the four participants who were audio-recorded, the journey of one learner is presented. This data was analysed using a microgenetic approach with LREs (Swain and Lapkin, 1995, 1998, 2002) as the unit of analysis. The microgenetic analysis shows how working collaboratively provides learners with access to a shared cognitive space. Within this space, they can employ language as a cognitive tool to access other-regulation from their peers and deploy their own self-regulatory strategies. The experience of an individual was explored within the context of the linguistic gains made by the collective to whom he belongs. Thus, even though the statistical analysis of the results suggests that working collaboratively is not more effective in facilitating learners’ linguistic development than working individually, the process of language learning has been connected to the outcome of language learning through the results of the descriptive statistics and the microgenetic analysis. This study contributes to a better understanding of: the types of pedagogies that may be effective in a Qatari undergraduate context, why collaborative learning can be effective, how knowledge which is initially social can take on a psychological function, and how the Vygotskian sociocultural methodologies of the genetic method and dynamic assessment can be integrated into an SLA design

Becoming phonemically aware: A study on the role of assistance in language learning

This was a Sociocultural study of second language learning involving Vygotsky\u27s Zone of Proximal Development (Vygotsky, 1978; & Newman and Holzman, 1993), phonemic awareness (Adams, 1990, Lieberman & Shankweiler, 1985), and dynamic assessment (Campione and Brown, 1987; Feuerstein, 1979; and Budoff, 1987). This inquiry was aimed at understanding how assistance functions in second language learning, uncovering student abilities in collaboration through an L2 dynamic assessment of phonemic awareness, and determining what information is available with an L2 dynamic assessment of phonemic awareness. This investigation illuminated teacher-to-student and student-to-student assistance in assessing/learning a second language during a Dynamic Assessment of L2 Phonemic Segmentation and subsequent intervention lessons. This study was guided by the following research questions: (1) How does assistance function in the language and literacy development of primary-aged ELLS? (2) What information does a dynamic assessment of L2 phonemic awareness provide that a static assessment does not?;This study involved the researcher and 5 first grade English Language Learner (ELL) students working in collaboration in L2 dynamic phonemic awareness assessment and intervention lessons.
