Dr Sam Calder is a speech pathologist, clinical educator, academic, and researcher. He is passionate about evidence-based practice in speech-language pathology and evaluating the effectiveness of paediatric speech, language, and literacy interventions. In particular, his work has focused on improving outcomes for early school-aged children with Developmental Language Disorder.

Biography

Prior to joining the University of Tasmania, Sam was a sessional academic and project officer at Curtin University in Perth, Western Australia. Sam completed his Master of Speech Pathology in 2014 at Curtin University for which he was awarded Best Overall Performance, the Speech Pathology Australia Prize- Most Outstanding Clinical Performance, and the Speak Easy Award for Most Outstanding Clinical Work in the Area of Stuttering. Sam also completed his PhD in Human Communication Sciences in 2021 at Curtin University. Sam has extensive clinical experience with early school-aged children with speech, language, and literacy difficulties. He worked as a speech pathologist for the Department of Education at a specialised school for children with Developmental Language Disorder for seven years. During this time, Sam also worked as an Outreach Officer where he collaborated with mainstream educators to implement best practice in classroom support for children with speech, language, and literacy needs. Sam also oversaw the clinical education of final year speech pathology students at the specialised school for which he was nominated as the 2021 Clinical Educator of the Year.

Research Themes

Sam's research aligns to the University's research theme of Better Health. His research interests include understanding the linguistic and cognitive contributors to language development, and evaluating the efficacy and effectiveness of interventions for children with developmental disorders, including effective models of service delivery. Sam's research takes a programmatic approach to clinical outcome testing to inform evidence-based practice in the implementation of language and literacy interventions. In particular, Sam has tested interventions to improve the grammar skills of children with language disorder, as this is a known area of deficit for these children. By evaluating efficacious and effective methods to improve broad areas of deficit, findings can be used to design interventions to target other known areas of difficulty in language use and understanding, as well as literacy skills. He is particularly interested in testing the parameters of intervention, such as dosage and intensity. Sam has also evaluated the grammar skills of children with Developmental Language Disorder to identify areas of deficit to inform assessment and treatment planning through speech pathology practice. Sam is currently working on the Raine Birth Study, one of the world's largest prospective birth cohort studies, where he is investigating the prevalence and early predictors of Developmental Language Disorder, and later educational, vocational, and socio-emotional outcomes. Sam's research aims to inform the practice of speech pathologists, allied health professionals, and educators to improve health and educational outcomes for vulnerable paediatric populations.

Collaboration

Sam is currently involved in an international project with researchers from the UK, Ireland and Australia which aims to evaluate the effects of dose on grammar outcomes for children with Developmental Language Disorder. He is also involved in the Raine Study in collaboration with researchers at Curtin University, Perth Children's Hospital, and Telethon Kids Institute.

Current projects

  • Grammar elicitation of children with and without Developmental Language Disorder
  • Grammaticality judgement of children with and without Developmental Language Disorder
  • Tracking Developmental Language Disorder across the lifespan in the Raine Study
  • The effectiveness of morphosyntactic intervention for children with Developmental Language Disorder and the impact of within session dose

Fields of Research

  • Speech pathology (420110)
  • Allied health and rehabilitation science (420199)
  • Community child health (420601)

Research Objectives

  • Allied health therapies (excl. mental health services) (200301)
  • Provision of health and support services (200399)
  • Clinical health (200199)
  • Diagnosis of human diseases and conditions (200101)
  • Public health (excl. specific population health) (200499)

Publications

Sam is committed to conducting clinically grounded and relevant research which aims to inform and improve practice for allied health practitioners, including speech pathologists. His research has been published in several high-impact international journals, including the Journal of Speech, Language, and Hearing Research and the International Journal of Language and Communication Disorders. Sam also contributes regularly to clinically focused journals, such as Child Language Teaching and Therapy and the Journal of Clinical Practice in Speech-Language Pathology.
