Proportional Reasoning in Nursing Practice

Journal for Research in Mathematics Education, 2001
We investigate how expert nurses undertake the calculation of drug dosages on the ward. This calculation is error-critical in nursing practice and maps onto the concepts of ratio and proportion. Using episodes of actual drug administration gleaned from ethnographic study, we provide evidence that experienced nurses use a range of correct proportional ...

Proportional Reasoning and Percent

2016
Schoenfeld (1992) notes that constructivism rooted in Piaget is grounded in the belief that “…learning proceeds through construction not absorption” (p. 340). He surmises that teacher beliefs directly influence their pedagogy, he notes a teacher who believed that, “…mathematics is fixed and predetermined, as dictated by the physical world” (p.

Proportional reasoning in young children: The parts and the whole of it.

Journal of Educational Psychology, 1997
Evidence concerning intuitive foundations for fraction learning was obtained in a study of early developments in proportional reasoning. Children aged 5 to 7 years (kindergarten to 2nd grade) were given problems constructed so as to differentiate between reasoning based on the relations of a part to the whole versus reasoning based on relations between

The structure of prospective kindergarten teachers’ proportional reasoning

Journal of Mathematics Teacher Education, 2011
Lamon (Teaching fractions and ratios for understanding. Essential content knowledge and instructional strategies for teachers, 2nd edn. Lawrence Erlbaum Associates, Mahwah, 2005) claimed that the development of proportional reasoning relies on various kinds of understanding and thinking processes.

Analysis of the Proportional Distribution Formalization Process on the Perspective of Proportional Reasoning

The Korean Society of Educational Studies in Mathematics - School Mathematics, 2022
The aim of this study is to offer suggestions to improve proportional reasoning ability for teaching and learning proportional distribution and to derive the proportional distribution formalization process on the perspective of proportional reasoning, and analyze the formalization process on the perspective of teaching mathematical expressions.

Connecting Research to Teaching: Proportional Reasoning

The Mathematics Teacher, 1993
The attainment of proportional reasoning is considered a milestone in students' cognitive development. According to the NCTM's Curriculum and Evaluation Standards (1989), this ability is “of such great importance that it metits whatever time and effort must be expended to assure its careful development” (p. 82).

Developing Proportional Reasoning with Ratios

2012
Proportional reasoning has been recognised as a crucial focus of mathematics in the middle years and also as a frequent source of difficulty for students (Lamon, 2007). Proportional reasoning concerns the equivalence of pairs of quantities that are related multiplicatively; that is, equivalent ratios including those expressed as fractions and percents.
