Understanding linear measurement: A comparison of filipino and new zealand children

Medidas de longitud: Propuesta para la comprensión del uso de la regla convencional

“…Son varios los estudios en los que se hace patente la necesidad de dicha instrucción, pues demuestran que el rendimiento en tareas de medida con regla es bajo. En estos trabajos, el instrumento suele estar alterado (la regla que utilizan está rota) porque el estudio se centra en el punto de origen de las mediciones (Bragg y Outhred, 2000Irwin, Ell y Vistro-Yu, 2004;Kamii, 1995;Nunes, et al, 1993).…”

Internationalisation and Globalisation in Mathematics and Science Education

“…For example, the main goal of the science educator who came to New Zealand was to explore a wider range of journal publications in science education than were available in her country, with the guidance of a science educator in New Zealand. Likewise, the authors of this chapter set up a larger research study, now published, that explored young children's concepts and misconceptions in measurement in both countries, and compared these with the curriculum in the two countries (see Irwin, Vistro-Yu & Ell, 2004). One of the Filipino visitors decided to undertake his doctoral studies in New Zealand, thus increasing the knowledge that he will take back to the Philippines.…”

Children’s unit concepts in measurement: a teaching experiment spanning grades 2 through 5

“…Similarly, Langrall et al (2008) indicate the generality and importance of unit concepts in a theoretical perspective for the mathematics curriculum. Students appeared to benefit as they worked on measuring tasks emphasizing common unit and structuring concepts across spatial dimensions of length, perimeter, area and volume (Irwin, Vistro-Yu, & Ell, 2004;Mulligan, et al, 2005). Focusing on unit concepts has apparent benefits, but little is known about the kinds of decision making and task design considerations involved as a researcher and her students investigate unit concepts across a range of contexts from length, area and volume measurement.…”
