Through the years, and probably through the centuries, teachers have struggled to make math meaningful by providing students with problems and examples demonstrating its applications in everyday life. As this classic joke shows, some strategies are more successful -- and more meaningful -- than others! Teaching Math in 1950: A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit? ...

Introduction The study of simultaneous interpreting presents a formidable challenge to the linguist and psychologist alike. Psycholinguistic models meant to shed light on the complexity of the process in question have been developed and refined by several scholars (Gerver, 1976, Moser, 1978, Levelt, 1989, de Boot, 1995). This paper is a discussion of one of the processes included in these current views of simultaneous interpretation, namely the decoding process usually referred to as -speech perception-. This process involves the reception of speech sounds and their decoding into lingui...
