Building science through questions in Content and Language Integrated Learning (CLIL) classrooms

Background The growing population of students that are learning science through a Content and Language Integrated Learning approach (CLIL) has led to concerns about these students’ ability to fully participate in a rich classroom discourse to develop content knowledge. A lack of information about science development through classroom discourse in CLIL settings brought us to focus on the questions teachers ask in upper secondary CLIL biology classrooms. Our aim was to understand how these questions effect science content learning opportunities. A multiple-case study design was implemented to examine and understand the complexities of teacher-student interactions. Data were collected in three case studies, each located in a different school (two in Germany and one in Italy), where CLIL senior secondary science classrooms were observed and audio-recorded. Classroom talk transcripts were analyzed using a mixed methods approach to discourse analysis. Results Findings suggest that a teacher’s strategic use of questions has the potential to promote both science understanding and science language development. Questioning contingent on students’ answers was observed to both promote content understanding and to lessen the linguistic demand on CLIL students by splitting both reasoning processes and language production into more manageable units. In addition, a higher level of cognitive engagement was present only when students managed to participate in the classroom discourse with answers longer than single utterances. To allow students to actively participate in the classroom discourse, teachers were observed adopting and promoting translanguaging practices, that is, the flexible use of more than one linguistic code. Furthermore, teachers asked language-related questions that promoted both understanding and use of disciplinary language. Conclusions The questioning practices observed in this study offer both practitioners and researchers ways of understanding issues of content access in upper secondary CLIL science classrooms. We recommend STEM teachers in CLIL settings not to oversimplify the linguistic demand on students, as this leads to an oversimplification of content. To lessen the linguistic barriers, practical strategies are recommended to support both cognitively and linguistically productive questioning in STEM CLIL classrooms.

Distinct Neural Correlates of Linguistic and Non-Linguistic Demand

In this study, we investigated how the brain responds to task difficulty in linguistic and non-linguistic contexts. This is important for the interpretation of functional imaging studies of neuroplasticity in post-stroke aphasia, because of the inherent difficulty of matching or controlling task difficulty in studies with neurological populations. Twenty neurologically normal individuals were scanned with fMRI as they performed a linguistic task and a non-linguistic task, each of which had two levels of difficulty. Critically, the tasks were matched across domains (linguistic, non-linguistic) for accuracy and reaction time, such that the differences between the easy and difficult conditions were equivalent across domains. We found that non-linguistic demand modulated the same set of multiple demand (MD) regions that have been identified in many prior studies. In contrast, linguistic demand modulated MD regions to a much lesser extent, especially nodes belonging to the dorsal attention network. Linguistic demand modulated a subset of language regions, with the left inferior frontal gyrus most strongly modulated. The right hemisphere region homotopic to Broca’s area was also modulated by linguistic but not non-linguistic demand. When linguistic demand was mapped relative to non-linguistic demand, we also observed domain by difficulty interactions in temporal language regions as well as a widespread bilateral semantic network. In sum, linguistic and non-linguistic demand have strikingly different neural correlates. These findings can be used to better interpret studies of patients recovering from aphasia. Some reported activations in these studies may reflect task performance differences, while others can be more confidently attributed to neuroplasticity.

Writing Feedback Groups in International EAL Doctoral Students' Development as Scholarly Writers

For many international doctoral students, English is an additional language (EAL), and consequently, scholarly writing in English is a source of academic anxiety. Although international English as an additional language (IEAL) students often have professional experience in their field of study and have been academically successful, the shift in linguistic demand at the doctoral level is especially challenging. Learning to communicate as a member of the academic community requires the development of discipline specific knowledge, rhetorical conventions, and discourse registers which precisely communicate complex ideas in their nonnative language. Research evidence points to the importance of social support and feedback in international/EAL doctoral students' socialization into scholarly writing. This chapter outlines the implementation of a writing feedback group with four IEAL doctoral students and their developing scholarly habits of mind and academic writing skills.

The Relationship Between Grammatical Development and Disfluencies in Preschool Children Who Stutter and Those Who Recover

Purpose The dual diathesis stressor model indicates that a mismatch between a child's endogenous linguistic abilities and exogenous linguistic contexts is one factor that contributes to stuttering behavior. In the present study, we used a developmental framework to investigate if reducing the gap between endogenous and exogenous linguistics factors would result in less disfluency for typical children, children who recover from stuttering (CWS-R), and children who persist. Method Children between 28 and 43 months of age participated in this study: 8 typical children, 5 CWS-R, and 8 children who persist. The children were followed for 18 months with language samples collected every 6 months. The Index of Productive Syntax (Scarborough, 1990) served as a measure of endogenous grammatical ability. Length and complexity of active declarative sentences served as a measure of exogenous linguistic demand. A hierarchical linear model analysis was conducted using a mixed-model approach. Results The results partially corroborate the dual diathesis stressor model. Disfluencies significantly decreased in CWS-R as grammatical abilities (not age) increased. Language development may serve as a protective factor or catalyst for recovery for CWS-R. As grammatical ability grew and the gap between linguistic ability and demand decreased; however, none of the three groups was more likely to produce disfluencies in longer and more complex utterances.

A Systematic Examination of the Linguistic Demand of Cognitive Test Directions Administered to School-Age Populations

The selection and interpretation of individually administered norm-referenced cognitive tests that are administered to culturally and linguistically diverse (CLD) students continue to be an important consideration within the psychoeducational assessment process. Understanding test directions during the assessment of cognitive abilities is important, considering the high-stakes nature of these assessments. Therefore, the linguistic demand of spoken test directions from the following commonly used cognitive test batteries was examined and compared: Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), Woodcock–Johnson IV Tests of Cognitive Abilities (WJ IV COG), Cognitive Assessment System, Second Edition (CAS2), and Kaufman Assessment Battery for Children, Second Edition (KABC-II). On average, the linguistic demand of the standard test directions was greater than the linguistic demand of the supplementary test directions. When examining individual test characteristics, very few individual tests were identified as outliers with respect to the linguistic demand of their test directions. This finding differs from previous research and suggests that the linguistic demand of the required directions for most tests included in commonly used cognitive batteries is similar. Implications for future research and test development are discussed.

Linguistic Demands of the Oral Directions for Administering the WISC-IV and WISC-V

As the diversity of the school-age population in Canada continues to increase, it is important for school psychologists to consider the potential influence of culture and language when assessing the cognitive abilities of students from culturally and linguistically diverse backgrounds. The purpose of this study is to examine the linguistic demand of the oral subtest directions for the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) and Fifth Edition (WISC-V). Text-based statistics were extracted from the WISC-IV and WISC-V subtests to generate three composite scores: verbosity, complexity, and total demand. Results suggest that the oral directions of the WISC-IV subtests Block Design, Letter–number Sequencing, Cancellation, and Comprehension demonstrate relatively high linguistic demand. The oral subtest directions of the WISC-V subtests Picture Span, Visual Puzzles, and Figure Weights demonstrate relatively high linguistic demand. These findings suggest that the linguistic demand of oral directions should be taken into consideration when selecting and interpreting some subtests from both of these cognitive batteries.

The cognitive and linguistic demands of everyday, functional literacy tasks

After examining seminal research related to functional literacy and the national assessments of adult literacy, seven key cognitive and linguistic demands are proposed that everyday literacy tasks (e.g. reading a drug label) make: read words, comprehend sentences, search text, identify computations, perform computations, infer meaning, and apply information. The distinctiveness of the five non-quantitative task demands and their progression in difficulty were subjected to verification via independent psychometric analyses using 252 functional literacy tasks and responses of 46,000 adults aged 16 and older residing in households and prisons in the United States. The results of multidimensional item respond theory (MIRT) modeling indicate delineation among three sets of task demands. Findings are illustrated through application to a common task involving an over-the-counter drug label. Keywords: adult literacy; cognitive demand; functional literacy; linguistic demand; health literacy; over-the-counter drug labels
