This study developed the scale that assesses the ability of preschool teachers to promote children’s mathematical thinking, and conducted the situational analysis of Japanese preschool teachers. The purpose of this study was to develop the scale of the ability about promoting children’s mathematical thinking in preschool teachers and assess their ability. For that reason, a questionnaire was conducted to preschool teachers who were working in preschools (N = 157) and, a survey of exploratory factor analysis was conducted, which extracted seven factors: “The ability to read the play that leads to Basis of Mathematics (extensions)”, “Advice for leading to Basis of Mathematics”, “The way of thinking to Basis of Mathematics”, “Practice of childcare leading to Basis of Mathematics”, “The ability to read the play that leads to Basis of Mathematics (basics)”, “Understanding Basis of Mathematics”, and “The way of thinking to preschool education”. Then, the situational analysis was conducted. Results indicated the ability of preschool teachers to promote children’s mathematical thinking in preschool teachers was not at enough level. Furthermore, the t-test conducted on the several experiences of preschool teachers and the seven factors was investigated. Results indicated that on the five factors the average values of teachers who had an experience of working in kindergarten were higher than that of teachers who had no experience of working kindergarten. These results suggest that developing the scale to assess the ability of preschool teachers in order to promote children’s mathematical thinking is significant and by using this scale we become able to grasp the actual situation of the teachers and the important matter of teachers’ education.

Enhancement of science and mathematics education is required. A necessity of cultivating the basis of mathematics is increasing more and more. It is also necessary for preschool teachers to change their consciousness toward mathematics in early childhood education and to construct the play that leads to Basis of Mathematics. Especially mathematical thinking is important as Basis of Mathematics. But ability of preschool teachers to promote children’s mathematical thinking isn’t clarified and a scale to measure the ability isn’t developed.

The purpose of this study is to develop a scale for assessing preschool teachers’ ability in order to promote the early development of children’s mathematical thinking. This scale makes it possible to analyze the current situation of the preschool teachers for mathematics education in early childhood education.

The mathematics education in early childhood education has changed significantly in recent years. Basic developmental research conducted over the past 25 years has fundamentally changed the way in which the early development of mathematical thinking is understood (Starkey et al., 2004) . In the past, preschoolers were thought to have no mathematical knowledge because they could not use abstract numerical notation, such as written numerals or operation signs. For this reason, traditional learning theorists argued that the development of children’s mathematical knowledge began with the formal schooling of mathematics from elementary school (Bereiter & Engelman, 1966) . Piaget (1952) shifted the focus of research on the development of mathematical knowledge before formal schooling of mathematics. Piaget and Following researchers did not use abstract numerical notation to measure mathematical knowledge (Starkey et al., 2004) . This has made it possible to measure the effect of early childhood education on mathematics education, and to draw attention to its importance.

Since Piaget (1952) , many studies have shown that preschool children have mathematical skills. Geary (1994) , Ginsburg (1989) showed that mathematical knowledge developed before school provided a basis for acquiring formal mathematical knowledge in schools.

There is also research on the relationship between the educator’s ability and the children’s mathematical ability. A survey of California’s public and private preschool children’s teachers revealed that preschoolers consider the environment of preschool to be more important than that of home when preparing for school mathematics (Starkey et al., 2004) . Moreover, Kabita, et al., (2013) studied about the consciousness of preschool teachers for basic knowledge and mathematical activities. Furthermore, Lerkkanen, et al., (2012) examined the extent to which teaching practices observed in kindergarten classrooms predict children’s interest in reading and mathematics. The results revealed that the children showed more interest in reading and mathematics, in classrooms in which the teachers placed greater emphasis on child-centered teaching practices than on teacher-directed practices. These researches indicated that the teachers’ knowledge about mathematical education is important thing for the education of preschoolers.

About these increased attentions to early mathematics education, Chen et al. (2014) researched knowledge of what preschool teachers think about early math teaching and how confident they are in helping preschoolers learn math remains limited. The results they observed that level of teacher confidence varied with specific types of math knowledge and teaching abilities. And Sarama, et al., (2016) indicated about the importance of professional training to preschool teachers.

These studies provided the importance of knowledge and teacher education for mathematical education in preschool. And, regarding the development of mathematical ability, it was shown that the implementation in early childhood education was very important, and it was particularly significant that teachers in early childhood education had the ability to teach mathematical elements.

But the ability of preschool teachers to promote children’s mathematical thinking isn’t clarified and a scale to measure the ability isn’t developed. Therefore, we tried to develop a scale for assessing preschool teachers’ ability to develop the early development of children’s mathematical thinking.

There are three forms of early childhood education in Japan. The first form is a kindergarten as an educational institution. The second is a nursery school with a side as a childcare facility. The last form is a center for early childhood education and care with both sides as a child care facility and education institution. These are intended to fulfill the function as an early childhood education facility.

However, since the nursery school and a center for early childhood education and care have side as a child welfare institution, it is thought that education is less emphasized than at kindergarten. Childhood education in nursery schools and in a center for early childhood education and care is an urgent issue.

There is research on things that lead to “knowledge discovery and theorizing” on mathematics after elementary school in mathematics learning. Shunsuke et al. (2010) call “The rudimentary mathematics knowledge which is acquired through play activities” as “Basic Mathematics” (Gen-Sugaku). They regard that as “ability that become Basis of thinking logically (thinking) and Accurate cognition (cognition)” rather than just “basics of mathematics”.

Basic Mathematics is composed of a fundamental matter regarding contents of mathematics and a way of thinking which works for recognizing the fundamental matter. The former includes comparison, correspondence, classification, split, counting together, ordering, amount, measurement, distance, construction, immutability/conservability, position, topology, shape, continuity, sequence, division into cases, organizing, connectivity. The other includes reasoning, analysis, synthesis, essence, relationship, abstraction and generalization, changing viewpoint, visualization, reversibility, transition law, and logical thinking. Acquiring these basis mathematics through play in early childhood education could be thought strongly correlated to mathematical recognition in mathematics education.

Basic Mathematics does not include some elements which we consider pupils should acquire(experience) at pre-school before learning mathematics at primary school such as counting, subitizing, making half, part-whole relationship and so on.

Therefore, in this research, Basic Mathematics and some added elements mentioned above are defined as Basis of Mathematics.

Participants were teachers working in preschools (n = 157). All teachers were working in a center for early childhood education and care. 22 teachers had an experience to work in a kindergarten and a nursery school. 14 teachers had an experience to work in a kindergarten. 82 teachers had an experience to work in a nursery school. 35 teachers had only experience to work in a center for early childhood education and care.

At first we decided to select following four items as what affect ability to promote children’s mathematical thinking and as information we want to collect through questions; Experience of work as preschool teacher, Knowledge about Basis of mathematics, Consciousness toward children, play and childcare, and Practical ability of childcare such that creation of environmental constitution which leads to Basis of Mathematics, reading of the play and advising.

Regarding with each item, we set detailed questions tentatively with reference of Basis of Mathematics and asked principals of preschool about them. Based on their comments, we revised or delete questions and finally set 48 questions.

These indicate that teachers who are good or not good at mathematics, have or don’t have a license for elementary school, have or don’t have an experience of working nursery school, have or don’t have an experience of learning extension mathematics, and have or don’t have an experience of working a kindergarten.

First, average values and standard deviation for the 47 items of the ability of preschool teachers to promote children’s mathematical thinking were determined. In order to identify the ceiling and floor effects for each item, the average value ± standard deviation of the range from the minimum to the maximum value was determined. The average values and standard deviation of each item are shown in

A ceiling effect and a floor effect were not observed, and as all items were considered important to exploratory factor analysis in this study, they were not excluded from the analysis.

An analysis using the re-likehood method with Promax rotation was performed on the 47 items with an insufficient factor-loading (0.40) were excluded from the analysis.

The final factor patterns and factor correlations are displayed in

Seven factors were extracted as a result of the factor analysis.

The first factor was named the “The ability to read the play that leads to Basis of Mathematics (extensions)”. The second factor was named the “Advice for leading to Basis of Mathematics”. The third factor was named the “The way of thinking to Basis of Mathematics”. The fourth factor was named the “Practice of childcare leading to Basis of Mathematics”. The fifth factor was named the “The ability to read the play that leads to Basis of Mathematics (basics)”. The sixth factor was named the “Understanding Basis of Mathematics”. The seventh factor was named the “The way of thinking to early education”.

Then, an analysis of ability to promote children’s mathematical thinking in preschool teachers was conducted on several viewpoints.

The results indicated no significant difference in the scores about good or not good at mathematics, have or don’t have a license for elementary school, have or don’t have an experience of working nursery school, and have or don’t have an experience of learning extensional mathematics.

But the results indicated a significant difference in the scores about having or not having an experience of working a kindergarten.

Special effort to understand the relationship between children’s play and mathematical thinking is necessary for preschool teachers who had no experience of working in kindergarten. These findings indicated the important matter of teachers education.

This scale is useful for finding the important matter of teachers education.

In this study, a scale was developed to measure the ability of preschool teachers to promote children’s mathematical thinking. By analyzing the ability of preschool teachers to promote children’s mathematical thinking, we could understand the current state of preschool teachers in Japan. Therefore, we are able to state that the ability of preschool teachers to promote children’s mathematical thinking was not at enough level. In addition, it was shown that the ability to promote children’s mathematical thinking of preschool teachers who have no experience of working kindergarten was lower than that of teachers who have experience of working kindergarten.

Evaluating the ability of preschool teachers to promote children’s mathematical thinking by the scales is important for revealing current situation of preschool education and finding suggestion to teacher education.

However, this research is a survey of preschool teachers in one time, for this reason, the following three issues will be addressed in the future. The first is to conduct the same questionnaire in other preschool. This enhances the reliability of the analysis in this study.

The second is that it is necessary to conduct longitudinal surveys on the same teachers. This makes it possible to analyze the influence on the ability of preschool teachers to promote children’s mathematical thinking due to conducting in teachers education.

It will be possible to derive the relationship between teachers education and ability of teachers in more detail. The third is to provide in detail the contents of mathematics education in preschool.

Thus, unresolved problems remain in this research. However, developing the scale to assess the ability of preschool teachers to promote children’s mathematical thinking is significant and by using this scale we become able to grasp the actual situation of the preschool teachers and the important matter of teachers education. Furthermore, it can give a new viewpoint of assessing ability of mathematic thinking and understanding preschool teacher’s situation and each preschool’s situation.
