Problem-based learning: Student learning experiences and outcomes.
Abstract Abstract The aim of this article is to examine processes occurring within problem-based learning (PBL) courses (inside the black box) by contrasting these processes with outcome-based studies (from outside the black box). We review meta-analyses of input-output studies of PBL in comparison with traditional approaches and provide a summary of qualitative, phenomenographic and factor analytic analyses of student experiences when studying health sciences (dentistry and medicine) using PBL curricula. Results from meta-analyses showed PBL courses were preferred for the long-term retention of course content, sh...

The disfluent speech of a Spanish-English bilingual child who stutters.
This study provides a detailed description of the disfluent speech behaviours produced by a 6;1-year-old bilingual Spanish-English speaking female with confirmed stuttering. Eight language samples across different contexts (narratives and conversations) with the clinician in English and Spanish and the parent in Spanish were analysed. Language samples were transcribed in the Systematic Analysis of Language Transcripts programme and coded for types of disfluencies based on guidelines for monolingual English speakers. Similarities and differences were noted in speech disfluencies produced in English as compared Spanish. Over...

Lexical category influences in Persian children who stutter.
This article explores the effect that words from different lexical categories have on disfluency in 12 Persian children, ten boys and two girls, who stutter. They were aged 7 years 5 months to 10 years 6 months. Words from the participants' narrative and reading samples (sub-tests of the Reading and Dyslexia Test validated for Persian school-aged children) were categorized as content, function, or content-function, and stuttering-like disfluencies were coded in each speech sample. Content and content-function words were significantly more likely to show stuttering-like disfluencies than function words. The distribution of ...

Experiencing the role of PBL tutor.
This study aimed at investigating the PBL tutor's role. Five PBL tutors at the Speech/Language Pathology program were interviewed regarding their view of the tutors' role and what support they need. The analysis of the transcribed interviews focused on finding patterns and variation regarding tutor-activity at different stages in the PBL work and in their views of their progress as tutors. The results indicate that being a tutor is a balancing act and that the tutor need continuous support and input from different sources. Tutors should be encouraged to reflect on their own reactions and interventions and to be explicit an...

An exploration of novice and experienced problem-based learning facilitators' perceptions of their roles in a speech-language pathology programme. Does experience matter?
Abstract Abstract Recruitment and training of skilled facilitators is critical to the success of a problem-based learning (PBL) curriculum. However, facilitation skills do not come naturally to all staff and it remains unclear whether experience in the role contributes to competency. PBL facilitators in a Speech Pathology Masters programme were surveyed via questionnaire and open ended questions regarding their perceptions of the competencies needed to facilitate. Novice and experienced facilitators responses were then compared. The survey response rate was 82% (7/14 experienced and 7/14 novices). Two significant ...

Extended turn construction and test question sequences in the conversations of three speakers with agrammatic aphasia.
This article presents examples of turn construction methods deployed by three people with agrammatism as they take an extended turn, in order to recount a past event, initiate a discussion or have a disagreement. This is followed by examples of sequences occurring in the talk of two of these speakers that result in different, and more limited, turn construction opportunities, namely "test" questions asked in order to initiate a new topic of talk, despite the conversation partner knowing the answer. The contrast between extended turns and test question sequences illustrates the effect of interactional context on a...

Designing, implementing and evaluating an online problem-based learning (PBL) environment - A pilot study.
Abstract Abstract Problem-based learning (PBL) has been shown to be effective for promoting student competencies in self-directed and collaborative learning, critical thinking, self-reflection and tackling novel situations. However, the need for face-to-face interactions at the same place and time severely limits the potential of traditional PBL. The requirements of space and for meeting at a specific location at the same time create timetabling difficulties. Such limitations need to be tackled before all potentials of PBL learning can be realized. The present study aimed at designing and implementing an online PB...

This article focuses on methodological issues related to quantitative assessments of speech quality after glossectomy. Acoustic and articulatory data were collected for 8 consonants from two patients. The acoustic analysis is based on spectral moments and the Klatt VOT. Lingual movements are recorded with ultrasound without calibration. The variations of acoustic and articulatory parameters across pre- and post-surgery conditions are analyzed in the light of perceptual evaluations of the stimuli. A parameter is considered to be relevant if its variation is congruent with perceptual ratings. The most relevant acoustic param...

Abstract Abstract Aim of this study was to investigate at what age German children master prosodic and morphological constraints in the acquisition of the word formation paradigm -heit/-keit, which is comparable to English -ness, and whether children with Specific Language Impairment (SLI) have difficulties identifying the prosodic cues from the input. Derived words with -heit contain simple bases with final stress and those with -keit have complex bases with a weak final syllable. Three groups of typically developing children (four, six and eight years old) and 18 children with SLI (from 8 to 10 years) had to pro...

Effect of word accent on the difficulty of transition from core vowels in first syllables to the following segments in Japanese children who stutter.
Abstract Abstract Matsumoto-Shimamori, Ito, Fukuda, and Fukuda (2011) proposed the hypothesis that the transition from the core vowel (i.e. syllable nucleus) in the first syllable of a word to the following segment significantly affects the occurrence of stuttering in Japanese. The purpose of this study was to investigate whether word accent (i.e. an abrupt pitch fall in Japanese) affects the production difficulty of the transition from the core vowel in the first syllable of a word to the following segment in Japanese. The participants were 25 Japanese children who stuttered, ranging in age from 6;4 to 12;5. A tw...

Prosodic constraints on inflected words: An area of difficulty for German-speaking children with specific language impairment?
Abstract Abstract Recent studies suggest that morphosyntactic difficulties may result from prosodic problems. We therefore address the interface between inflectional morphology and prosody in typically developing children (TD) and children with SLI by testing whether these groups are sensitive to prosodic constraints that guide plural formation in German. A plural elicitation task was designed consisting of 60 words and 20 pseudowords. The performance of 14 German-speaking children with SLI (mean age 7.5) was compared to age-matched controls and to younger children matched for productive vocabulary. TD children pe...

This study is a cross-linguistic examination of the patterns of reduction of two-member /s/-clusters. Data from six languages (English, Dutch, Norwegian, Croatian, Hebrew, and Polish) gathered from the productions of typically developing children and from children with phonological disorders are analyzed. While the languages belong to three different families, the results point to a universal tendency. Specifically, in the reductions of "s+stop" and "s+nasal" targets, the preference is the retention of C2, whereas in /sl/ and /sw/ targets, the clear pattern is in favor of the retention of C1.

Tracking change in children with severe and persisting speech difficulties.
Abstract Standardised tests of whole-word accuracy are popular in the speech pathology and developmental psychology literature as measures of children's speech performance. However, they may not be sensitive enough to measure changes in speech output in children with severe and persisting speech difficulties (SPSD). To identify the best ways of doing this, we compared a range of commonly used procedures for perceptual phonological and phonetic analysis of developmental speech difficulties. Data are drawn from four children with SPSD, recorded at 4 years and again at 6 years old performing naming and repetition tas...

In this study, we focus specifically on the influence of the frequency of functional words on the ability of children with SLI to produce grammatical constructions based on the children's own previous production but containing previously unused functional words. To test our hypothesis, the children were administered an imitative repetition task, tailored to their current level of language development. Results showed that children with SLI performed more poorly than language-matched children with typical language development. The difference between the two groups was more marked when the previously unused functional words w...

Tongue-palate contact of perceptually acceptable alveolar stops.
Abstract Increased tongue-palate contact for perceptually acceptable alveolar stops has been observed in children with speech sound disorders (SSD). This is a retrospective study that further investigated this issue by using quantitative measures to compare the target alveolar stops /t/, /d/ and /n/ produced in words by nine children with SSD (20 tokens of /t/, 13 /d/ and 11 /n/) to those produced by eight typical children (32 /t/, 24 /d/ and 16 /n/). The results showed that children with SSD had significantly higher percent contact than the typical children for target /t/; the difference for /d/ and /n/ was not s...

Subject pronoun use by children with autism spectrum disorders (ASD).
Abstract In the current study, storytelling and story retelling by children with autism spectrum disorder (ASD) were analyzed to explore ambiguous third-person pronoun use in narratives. Twenty-three children diagnosed with ASD aged 6;1 to 14;3 and 17 typically-developing (TD) children aged 5;11 to 14;4 participated in the study. In the retelling task, no significant difference between the groups was found, suggesting that in less challenging tasks, children with ASD produce third-person subject pronouns appropriately. In the storytelling task, children with ASD produced more ambiguous third-person subject pronoun...

Agrammatism in Jordanian-Arabic speakers.
This study investigated the production of morpho-syntactic elements in 15 Jordanian-Arabic (JA) speaking individuals with agrammatism and 15 age-matched neurologically healthy individuals. Two experiments were conducted to examine the production of complementizer, tense, agreement and negation morphology in JA. The results indicated that the speakers of JA with agrammatism had marked dissociations in producing specific morpho-syntactic elements. The observed impairment patterns overlapped, in many respects, with those observed in other linguistic groups. The findings are discussed with respect to current theories of agramm...

The formulation of argument structure in SLI: an eye-movement study.
This study investigated the formulation of verb argument structure in Catalan- and Spanish-speaking children with specific language impairment (SLI) and typically developing age-matched controls. We compared how language production can be guided by conceptual factors, such as the organization of the entities participating in an event and knowledge regarding argument structure. Eleven children with SLI (aged 3;8 to 6;6) and eleven control children participated in an eye-tracking experiment in which participants had to describe events with different argument structure in the presence of visual scenes. Picture descriptions, l...

Speech and pause characteristics in multiple sclerosis: A preliminary study of speakers with high and low neuropsychological test performance.
Abstract This preliminary study investigated how cognitive-linguistic status in multiple sclerosis (MS) is reflected in two speech tasks (i.e. oral reading, narrative) that differ in cognitive-linguistic demand. Twenty individuals with MS were selected to comprise High and Low performance groups based on clinical tests of executive function and information processing speed and efficiency. Ten healthy controls were included for comparison. Speech samples were audio-recorded and measures of global speech timing were obtained. Results indicated predicted differences in global speech timing (i.e. speech rate and pause...
