Introduction
The capacity for preschool children to learn substantial mathematics at an early age is huge. However, due to circumstances, most of these children fail to get the opportunity. Others start on a schedule way behind their peers who are advantaged. This forms a basis of a negative trajectory of mathematics for many children. The interventions put in place to try help children learn mathematics at an early age impact their perception positively throughout their lives. This is what the article to be reviewed is based upon.
The article mentioned above is a quantitative study research. This is highlighted in the title of the article. At the same time, the researchers physically enter the classrooms they are surveying to obtain data through observation. It is done primarily to fulfill the measures of the research for instance classroom environment and fidelity. The authors recognized the need for evaluating the curricular rigorously. They also recognized the need for the evaluation of preschool mathematics curricula putting the focus on children from low or middle-class families. It was discovered that these children are less represented in such research yet they pose a huge risk mathematics problems in future.
The information the article provides is relevant for childhood education. This is because, mathematics, traditionally has been termed as one of the most challenging education. In addition, it is known that foundation of something determines its future. Relating to this, the future understanding of mathematics for the young learners depends on the foundation. All young learners, therefore, deserver an early mathematics foundation that is accessible, of high-quality and challenging. This experience should be provided to them through effective teaching and research-based curricula practices.
Article Summary
Purpose/ Rationale of the Study
The main purpose of the study was to measure the preschool mathematics program effectiveness. The comprehensive model development of the research-based curriculum formed the basis of the study. It was to be measured across teachers with diverse backgrounds. It purposed to answer a few research questions which aimed at finding out if building blocks curriculum could be developed with high fidelity. It also aimed at finding out if fidelity was a measure of achievement goals. It also purposed to find out if building blocks had a positive impact on the environment of learning mathematics. Lastly, it wanted to determine the effect of building blocks on preschoolers' achievement in mathematics and if the improvement in the quality of learning environment led to mathematics achievement.
Methodology
The methodology approach was quantitative which involved randomized- trials design. Thirty-six classrooms were selected based on the fact that they served preschoolers from low-income backgrounds. The classrooms were assigned randomly to the following three treatment categories 1) experimental, 2) comparison...
