Abstract

This study explored the development of Ecuadorian Kindergartners’ spontaneous focusing on numerosity (SFON) during the kindergarten year, as well as the contribution of early numerical abilities to this development. One hundred Kindergartners coming from ten classrooms received two SFON tasks, one at the beginning and one at the end of the school year, and an early numerical abilities achievement test at the beginning of the school year. Results first demonstrated limited SFON development during the kindergarten year, with inter-individual differences and intra-individual stability of children’s SFON tendency. Second, both children’s SFON tendency and their early numerical abilities at the start of the kindergarten year were predictively related to their SFON tendency at the end of the year. Our results do not only add to our theoretical understanding of SFON in young children, but also inform educational policy and practices in the domain of early mathematics education in Ecuador, as they provide building blocks for optimizing the educational goals and curricula for kindergarten mathematics.

Notes

  1. Subitizing is defined as an ability to accurately and immediately recognize a small number of objects in a collection (Kaufman et al. 1949).

    Children’s subitizing skill can be clearly distinguished from their SFON, as the former refers to the ability component of their early numerical competencies (i.e., children’s numerical knowledge and skills; see “Introduction” section of the manuscript), whereas the latter refers to the inclination component (i.e., children’s attentional processes in the domain of number). As defined by Hannula and colleagues, SFON involves children’s spontaneous attention for exact numerosity. To determine this exact numerosity, children can use their subitizing and/or their counting skills. Stated otherwise, after having spontaneously focused on the element of exact numerosity in the environment (SFON), children still have to actually determine the exact number of items and therefore rely on their subitizing and/or counting abilities.

  2. As it is not possible to administer children’s spontaneous focus on numerosity at test 2 via the same task as offered at test 1, we selected to highly similar parallel versions of the SFON Imitation Task. As discussed in Hannula-Sormunen (2015) and in Rathé et al. (in press), the SFON Parrot Imitation Task and the SFON Mail-box Imitation Task are both designed to capture children’s spontaneous attention for exact numerosity in non-mathematically focused situations and are characterized by exactly the same task requirements, procedures, and materials, except from the overall context (namely feeding a parrot with berries versus posting envelopes into a mailbox). As indicated by a recent study (Hannula–Sormunen et al. in preparation), the SFON Parrot Imitation Task and the SFON Mailbox Imitation Task are of equivalent difficulty: A group of 87 4–7-year-old children who were offered both variants of the SFON Imitation Task at one measurement time received an overall mean score of M = 1.98 (SD = 1.54) on the Parrot Imitation Task and of M = 2.15 (SD = 1.64) on the Mailbox Imitation Task, the difference between the two task scores being not statistically significant, t(86) = 1.62, p > .05.

  3. We used the non-parametric Wilcoxon signed-rank test as our SFON data do not follow a normal distribution.
