Prevalence of Voice Disorders in Iranian Primary School Students
Journal of Voice, 2017Co-Authors: Ali Mohammadzadeh, Nazila SandoughdarAbstract:Summary Objectives The voice is the sound produced by vibration of our vocal cords and has an important role in verbal communication. A child's voice disorder may significantly impair his or her ability to be heard and understood. The purpose of this study was to determine the prevalence of voice disorders in Primary School Students. Methods and Materials In this descriptive-analytical study, a total of 501 fourth through fifth grade Primary School Students (boys = 51.6%, girls = 48.4%) with the age range of 10–12 years were selected from nine public School systems in Tehran that were assessed in October 2013 through March 2014. Presence of a voice disorder characterized by hoarseness was identified by a dual approach including investigator screening and parent identification. We used the grade of overall dysphonia, roughness, breathiness, asthenia, and strain scale for perceptual evaluation of voice. All children were assessed with video laryngoscopy examination by an otorhinolaryngologist. The recordings were made during spontaneous speech, counting numbers, sustained utterance of the (/a/) vowel, reading a standard passage in Farsi, and the ratio of /s/ and /z/. Statistical analysis was done via chi-square test and t test. Results Results indicated that the prevalence of voice disorders in Primary School Students is 53.2%. The results indicated significant differences between gender and subjects with lesions ( P = 0.00000), gender and vocal disorders ( P = 0.04), and s/z ratio and type of lesion ( P = 0.0002). Conclusion Phonotrauma seems to play an important role in child dysphonia, with nodules as main diagnosis.

SPEECH DISORDERS IN Primary School Students OF ISFAHAN (1998-9)
Journal of Research in Medical Sciences, 2002Co-Authors: B ShafieiAbstract:Introduction. The aim of this study was to describe frequency of speech disorders in Primary School Students. Methods. In a cross-sectional study 300 first and second grade Primary School Students were examined for speech disorders. Results. From 300 subjects, 280 were normal (without speech disorders), 15 had articulation disorders, 2 had voice disorders, 3 had resonance disorders and no one had fluency disorders. Discussion. The findings of this study are supported by fomer study in other countries, except frequency of fluency disorders which may due to low sample size of present study.

Supporting Primary School Students’ reasoning about motion graphs through physical experiences
ZDM, 2019Co-Authors: Carolien Duijzer, Marja Van Den Heuvel-panhuizen, Michiel Veldhuis, Michiel DoormanAbstract:Reasoning about graphical representations representing dynamic data (e.g., distance changing over time), including interpreting, creating, changing, combining, and comparing graphs, can be considered a domain-specific operationalization of the general twenty-first century skills of creative, critical thinking and solving problems. This paper addresses the issue of how these 21st century skills of interpreting and creating graphs can be supported in a six-lesson teaching sequence about graphing motion. In this teaching sequence, we focused on the potential of an embodied learning environment to facilitate the development of Primary School Students’ reasoning about motion graphs by having Primary School Students (9–11 years) ‘walk’ graphs in front of a motion sensor to generate distance-time graphs. We asked: How does Students’ reasoning about graphing motion develop over a six - lesson teaching sequence within an embodied learning environment? Based on the collected data, we examined changes in Students’ level of reasoning on graph interpretation and graph construction tasks using a repeated measurement design. Additionally, we present two teaching episodes showing instances of how perceptual-motor experiences during the lessons aided Students’ reasoning about graphical representations of motion. Results show that Students went from iconic understanding towards understanding in which they reasoned based on one or two variables when interpreting and constructing graphical representations of motion events. At these higher levels of reasoning these Students showed understanding of modelling motion in line with the intended 21st century skills of generating, refining, and evaluating graphs.

Career Development of Upper Primary School Students in Turkey.
Australian Journal of Guidance and Counselling, 2013Co-Authors: Serap NazliAbstract:The purpose of this exploratory-descriptive study was to determine the career development of upper Primary School Students in Turkey. The Revised Career Awareness Survey (RCAS) was completed by 644 Turkish upper Primary School Students. Results indicated that the Students were able to associate their own personal characteristics with particular careers and knew the characteristics of careers. They were less knowledgeable about life/career implications and life/career management tasks. The implications of the findings for career guidance and counselling practice are considered.
