The study’s goal was to provide an educational intervention in Algebra through GeoGebra that would boost students’ confidence, improve their learning, and correct their most minor mastered skills, allowing them to improve their Algebra performance. The research design was quasi-experimental, with 40 nonrandomly chosen participants comprising the GeoGebra and control groups. Mean and standard deviation was employed to describe the algebra performance and confidence of the respondents. At the same time, independent and dependent t-tests were used to determine the students’ (...) significant difference in algebra performance and confidence in the pre-and post-test between the control and GeoGebra groups. GeoGebra effectively improved algebra confidence, enhanced learning, and remedied the students’ least mastered skills. GeoGebra is recommended as an instructional material in teaching and learning Algebra and can be extended to other mathematics content areas. (shrink)

From his initial writings on imagination and memory, to his recent studies of the glance and the edge, the work of American philosopher Edward S. Casey continues to shape 20th-century philosophy. In this first study dedicated to his rich body of work, distinguished scholars from philosophy, urban studies and architecture as well as artists engage with Casey's research and ideas to explore the key themes and variations of his contribution to the humanities. -/- Structured into three major parts, the volume (...) reflects the central concerns of Casey's writings: an evolving phenomenology of imagination, memory, and place; representation and landscape painting and art; and edges, glances, and voice. Each part begins with an extended interview that defines and explains the topics, concepts, and stakes of each of area of research. Readers are thus offered an introduction to Casey’s fascinating body of work, and will gain a new insight into particular aspects and applications of Casey's research. -/- With a complete bibliography and an introduction that at once stresses each of Casey’s areas of research while putting into perspective their overarching themes, this authoritative volume identifies the overall coherence and interconnections of Edward S. Casey's work and his impact in contemporary thought. (shrink)
