Theory of Authentic Task Situations (Torulf Palm)
Segue um pequeno spoiler para ver se anima alguém de ler com mais cuidado e nos ajude trazendo a discussão. Se ler, avise abaixo, por favor.
Definição de "Word problems" (sic): “textual descriptions of situations assumed to be comprehensible to the reader, within which mathematical questions can be contextualized"
There are several reasons for the inclusion of applications and modeling (including word problems) in mathematics education. The reasons include the possibilities of the use of applications and modeling to (1) facilitate the learning of necessary skills for being able to use (and critically examine the use of) mathematics outside the mathematics classroom, and (2) facilitate the development of an experience of school mathematics as useful and powerful for solving meaningful task situations in life outside the mathematics classroom.
However, many researchers (and teachers and students) have argued that too many word problems are “pseudo-realistic” and require the students to think differently than in out-of-school task situations (e.g., Boaler, 1993; Nesher, 1980; Verschaffel et al., 2000).
Example 3 (Carpenter, Lindquist, Matthews, & Silver, 1983). 360 students will go by bus on a school trip. Each bus can hold 48 students. How many buses are required?
Example 4. All students in the school will, on the 15th of May, go on a school trip together. You have decided that everyone will go by bus, and that you shall order the buses. You have seen in the student name lists that there are 360 students in the school. Your teacher said that you can order the buses from Swebus, and that each bus can hold 48 students. Fill in the note below, which you are going to send to Swebus to order the buses.
Swebus – Bus order Your name:.................................................................. School:....................................................................... Date of the trip:............................................................ Number of buses to order:.............................................
