Children's early accuracy on place value (PV) tasks longitudinally predicts their later multidigit calculation skills. However, another window into children's emerging base-ten concepts is the pattern of errors -- "smart errors" -- they exhibit on these measures. Past research has speculated that these smart errors -- similar to invented…

Young children's early repeating patterning abilities are important foundations for their later mathematical development. Prior studies on young children's repeating patterning abilities have been conducted exclusively in developed countries differing in economic, societal, and educational characteristics from developing countries. In this study,…

Mistakes are at the crux of daily classroom learning. This is the case even in the earliest grades. While the instructional value of mistakes is wellknown among educators, little research documents how young children experience mistakes in real-world school settings. In the present study, I conducted semi-structured interviews with 25 Kindergarten…

Research Findings: The aim of this study was to investigate U.S. preschool teachers' math teaching knowledge in a specific content domain: counting and numbers. One hundred in-service and pre-service teachers participated in the study; they completed a questionnaire that is composed of learning scenarios and scenario-based math teaching questions.…

Purpose: This study investigated the auditory comprehension of Japanese sentences including relative clauses (RCs) by 52 Japanese-speaking children with typical development (TD) and 16 children with specific language impairment (SLI). Method: A picture-pointing task measured RC and main clause (MC) comprehension for object and subject relatives in…

In this study, it is aimed to examine the level of oral reading of the students studying on their 3rd degree, who are at the age range of 60-66 months, and the students who completed their 72nd month and started primary school. The sample of the study is constituted of 100 students in the 3rd grade who study in primary schools Usak city center. 51…

Now, more than ever, American students at all grade levels face intense pressure to increase academic performance--including kindergarteners. Given that prior research has well established that mistakes and corrective feedback are key elements of the learning endeavor, it is critical to closely examine teachers' mistake-related experiences within…

Once the reasons for habitual observation in the classroom have been established, and the intent to observe has been settled, the practical details of observation must be organized. In this article, O'Shaughnessy gives us a model for the implementation of observation. She thoroughly reviews Montessori's work curves and how they can be used to show…

In recent years, the idea of language influencing the cognitive development of an understanding of place value has received increasing attention. This study explored the influence of using explicit number names on pre-kindergarten and kindergarten students' ability to rote count, read two-digit numerals, model two-digit numbers, and identify the…

The Decennial Census is the most important data collection activity undertaken by the U.S. federal statistical system. Because census data are used to apportion Congress and draw redistricting lines for thousands of state and local single-member districts to meet the one-person/one-vote guidelines, the census is at the heart of the political…

It is one thing to be able to count and share items proficiently, but it is another thing to know how counting and sharing establish and identify quantity. The aim of the study was to identify which measures of numerical knowledge predict children's success on simple number problems, where counting and set equivalence are at issue. Seventy-two…

Letter names play an important role in early literacy. Previous studies of letter name learning have examined the Latin alphabet. The current study tested learners of Hebrew, comparing their patterns of performance and types of errors with those of English learners. We analyzed letter-naming data from 645 Israeli children who had not begun formal…

The Malay language has a transparent morphological system and, unlike English, it is written in a very shallow alphabetic-syllabic script. We predicted that beginner spellers (six-to eight-year-olds) of this Rumi script would encode words at the level of the syllable and morpheme, rather than the phoneme. Using the results of a 75-item spelling…

Although there is extensive documentation of the morphological limitations of children with specific language impairment (SLI), few studies have reported on complex syntax acquisition in children with SLI. This case study examined the development of complex syntax in a child with SLI between 3 and 7 years. Twelve conversational samples were…

This volume of the 30th annual proceedings of the International Group for the Psychology of Mathematics Education conference presents: plenary panel papers; research forum papers; short oral communication papers; and poster presentation papers from the meeting. Information relating to discussion groups and working sessions is also provided.…
