| Résumé: | This study aimed to investigate the effectiveness of a finger-counting stimulation program
for the development of mathematical skills. Two articulated studies were carried out in
order to answer the research questions. The first one aimed to adapt the instructional
material developed in Germany, establishing the canonical pattern of finger-counting
among children from the city of Natal / RN / Brazil. One-hundred university students
from this city, 50 women and 50 men, participated in this study. They performed two
tasks, namely laterality and ordinality. Results pointed out the existence of canonical
pattern of counting with the fingers in Natal / RN / Brazil. The second study investigated
the effectiveness of the finger-stimulation program in counting on the development of
mathematical skills. This was a predominantly quantitative quasi-experimental
prospective and interventive longitudinal study. The sample of participants was formed
by 40 children of both sexes, with ages varying from 6 to 7 years. They were 1
st year
elementary school I students from two regular classes from a public school in the city of
Natal-RN. One class (experimental group) was submitted to the 18-week fingertip
stimulation program. The second group (control group) carried out the activities planned
by the school. The general, somatosensory and mathematical cognitive abilities of both
classes were assessed by the beginning and by the end of the 18 weeks period. There was
no statistical significant difference between the two groups in the pre-test evaluation.
However, in the post-test, significant differences were identified between the classes, in
favor of the experimental group, in addition skills, digital gnosia, numerical magnitude
and representation. These results allowed to identify the effectiveness of the program,
which on the other hand will support effective interventions and public policies aimed to
minimize school difficulties in mathematics identified among Brazilian children in
national and international assessment instruments. |
