Theoretical frameworks for the learning of geometrical reasoning
No full textWith the growth in interest in geometrical ideas it is important to be clear about the nature of geometrical reasoning and how it develops. This paper provides an overview of three theoretical frameworks for the learning of geometrical reasoning: the van Hiele model of thinking in geometry, Fischbein’s theory of figural concepts, and Duval’s cognitive model of geometrical reasoning. Each of these frameworks provides theoretical resources to support research into the development of geometrical reasoning in students and related aspects of visualisation and construction. This overview concludes that much research about the deep process of the development and the learning of visualisation and reasoning is still needed
The shaping of student knowledge: learning with dynamic geometry software
No full textThe focus of this paper is a software genre usually referred to as ‘dynamic geometry’ because of the ability of the user to dynamically manipulate geometrical figures created with the software tool. Using data from a longitudinal study of 12-13 students’ use of dynamic geometry software, the focus of the analysis is on the interpretations the students make of geometrical objects and relationships when using this form of software. The analysis suggests that the students’ mathematical reasoning is shaped by their interactions with the software in that their ability to explain geometrical facts and relationships evolves from imprecise, ‘everyday’ expressions, through reasoning that is overtly mediated by the software environment, to mathematical explanations of the geometric situation that transcend the particular tool being used. Such findings suggest that curriculum initiatives that encourage the use of dynamic geometry software are appropriate but that the incorporation of such software into classroom practices is unlikely to be straightforward

Elements of the visualisation process within a dynamic geometry environment
No full textThe advent of powerful computer graphic packages has coincided with renewed interest in all forms of visual representation in mathematics. As a result, we need to be clear about what we mean by the visual processing necessary to solve mathematical problems involving visual phenomena. Visual processing involves the ability to mentally manipulate and transform visual representations and visual imagery. This paper describes three different elements of the visualisation process: crude visualisation, visualisation as the reading of visual information, and visual processing. Illustrations are given of how the use of a dynamic geometry package such as Cabri-Géomètre both needs and contributes to developing visualisation in all these three senses
The mediation of mathematical learning through the use of pedagogical tools: a sociocultural analysis
No full textA sociocultural analysis suggests that pedagogical artifacts employed in the teaching and learning of mathematics both enable and constrain learning. This paper summarises three classroom studies of mathematics learning that have utilised a sociocultural approach. Each of the studies indicates how insight can be gained into the ways in which students attempt to make sense of the mathematics they encounter

Item 33, Juan P. Moreno portrait with guitar for Voltage Discos/Sony (4-color offset, 17 x 25 inches), undated
No full textThe Keith Ferguson collection includes artifacts, manuscripts, and audio-visual materials from the childhood and professional career of the internationally respected musician.Keith Ferguson, noted bass guitarist, was born on July 23, 1946. He was raised in the Sixth Ward of Houston, Texas, and graduated from San Jacinto High School in 1964. Ferguson, who played left-handed, worked with Carlos Santana, Johnny Winter, Peter Kaukonen, Jimmy and Stevie Ray Vaughn. He was a founding member of The Fabulous Thunderbirds and played with groups such as Night Crawlers, Texas Cajun Trio, The Tail Gators, and Big Guitars from Texas.Ferguson was nominated for a Grammy in 1986 for his work with the Big Guitars (a strictly instrumental, Austin-based band). He also won the Austin Music Award for Best Bass Guitar in 1985, and in 1997 he was inducted into the Austin Music Hall of Fame. Keith Ferguson died in Austin on April 29, 1997, of liver failure
