Geometry Test

Test instruments are an important element of almost every study in mathematics education, and the test that is used obviously affects the results of the study. Yet often a test is assumed both valid and reliable, and neither its content nor its psychometric properties are given scrutiny. The analyses Crowley and Wilson have done with the Van Hiele Geometry Test are welcome.

Part Model

Recently the work of Pierre M. van Hiele and Dina van Hiele-Geldofhas gained prominence in the study of the teaching and learning of geometry. Their three-part model (a) describes five sequential and discrete levels learners pass through as geometric thought develops, (b) discusses the nature of insight into geometric concepts, and (c) presents a guide to the development of geometric lessons. A detailed description of the complete model can be found in Crowley (1987).

Autism Diagnostic Observation

ADOS-2 is considered the gold standard observational instrument for use in the diagnosis and/or classification of autism and ASD. In this chapter, the process of assessment will be described, which involves direct observation and engagement of children and adults for whom an ASD is suspected. Specifically, an emphasis will be put on ADOS structure, namely the five different modules for the assessment. Then, the advantages of ADOS-2 will be elaborated as a diagnostic tool and a brief review of studies concerning its psychometric properties will be reported.

Introduction: Due to the necessity of assessing the health-related quality of life (HRQOL) in heart failure (HF) and the increased use of the International Classification of Functioning, Disability, and Health (ICF) for making a content comparison of measurement instruments, the present study aimed to evaluate the relationship between the instruments and ICF. To this aim, the disease-specific HRQOL instruments in HF were identified, and then psychometric properties and content comparison of included instruments were conducted by linking to ICF. Methods: Disease-specific HRQOL instruments in HF were identified through a comprehensive and systematic search strategy. Then, the psychometric properties of included instruments were determined, and their contents were analyzed and compared based on the ICF coding system. In addition, each instrument was independently linked to ICF by two researchers based on standardized linking rules, and finally their degree of agreement was assessed by the Cohen’s kappa coefficient. Results: Ten instruments including a total of 247 items and 417 concepts were linked to 124 different ICF categories. Further, 39 (31.5%), 65 (52.5%), 13 (10.4%), and 7 (5.6%) categories were linked to body function, activity and participation, environmental factors, and body structure, respectively. According to the content analysis approach and psychometric properties, the appropriate measurement instruments were Kansas City Cardiomyopathy and Minnesota living with HF questionnaires, respectively. Conclusion: Content comparison provides researchers with valuable information on the instrument heterogeneity and overlapping, which results in selecting the most appropriate measurement instrument based on a specific clinical context.

The World

This article approaches a qualitative research that had as objective to use some notions of euclidean geometry of students of a nineth year of Elementary School to realize the need to know some aspects of fractal geometry to understand the world in which they live. As a teaching methodology was used Van Hiele Theory for the development of reasoning in geometry with the software Geogebra in the construction of the fractal Pythagorean Tree. The students realized activities of classification of geometric figures and elements of nature, that allowed them to group them in properties or characteristics in two geometries and, with exploration of the photography resource, it was possible, for example, to identify the self-similarity characteristic of the fractal objects. The results of the research showed the efficiency of the Van Hiele Theory and Geogebra in the understanding of properties of the two geometries, in particular, on the Pythagorean theorem.
