Integrating Real-World Numeracy Applications and Modelling into Vocational Courses
( Hall Graham ) 한국수학교육학회 2013 수학교육 학술지 Vol.2013 No.-
Five levels are identified for incorporating applications and modelling into mathematics courses [Tang, A.; Sui, L. & Wang, X. (2003). Teaching patterns of mathematical application and modelling in high school. In: Qi-Xiao Ye, et al. (Eds.), Mathematical modelling in education and culture: ICTMA 10 (pp. 233-248). Chichester, UK: Horwood Publishing]: * Extension * Special Subject * Investigation Report * Paper Discussion * Mini Scientific Research These represent a progression from applications set by the teacher, through increasing student involvement in the solution of real world problems, to totally independent project work. Examples are given of the incorporation of these five levels of application to increase vocational students`` mathematical creativity and motivation. Case studies are presented from: engineering, construction, computing, and environmental science.

Objectives: Nocturnal hypoventilation is a complication of neuromuscular disorders. There are various recommendations for measuring pCO<sub>2</sub> during polysomnography and numerous national and international definitions of hypoventilation that could contribute to significant variations in clinical practice. We therefore aimed to determine clinical practices implemented by Australasian pediatric sleep physicians.Methods: Pediatric sleep physicians completed an electronic survey for information regarding pCO<sub>2</sub> measurements and definitions of hypoventilation that are followed for children with neuromuscular disorders.Results: It was found that transcutaneous measurement of pCO<sub>2</sub> was performed in all centers, with 25% of the centers simultaneously performing capnography. Twelve definitions of hypoventilation were used, including published definitions from the American Academy of Sleep Medicine (AASM) manual and recommendations of the pediatric Australasian Sleep Association/Australasian Sleep Technologists Association. The most commonly used definition of hypoventilation (9/17, 53%) was the 2012 pediatric AASM definition (pCO<sub>2</sub> >50 mmHg for >25% of the total sleep time). There was a discrepancy between centers and individuals within the same center when defining hypoventilation. Answers stating the use of the Australasian definitions (rise in pCO<sub>2</sub> ≥10 mmHg from wake to sleep, average rise in pCO<sub>2</sub> ≥3 mmHg from non rapid eye movement to rapid eye movement sleep) were more frequent when asked specifically via a checkbox (yes/no) compared to free text.Conclusions: These results confirm the heterogeneity and lack of standardization of clinical practice within Australasia when measuring pCO<sub>2</sub> during polysomnography and defining hypoventilation. The Australasian definitions were not used as frequently as anticipated.
