This book includes two main sections: a discussion of problem solving and a section on computation with whole numbers. A primary theme of the text is that problem solving sets the stage for meaning and conceptual development with respect to numbers. The section on problem solving includes numerous problem-solving activities that have a dual…

Classes of undergraduate Hispanic students assigned to two professors were identified to determine the level of cooperative learning being implemented and to allow the professors to reflect on their experiences over a full semester. Pre-semester and post-semester surveys were completed by each of the undergraduate students. This study is based…

Research examining the influence of collaborative learning experiences on students' intellectual development has been somewhat inconclusive and largely based on samples of white, traditional-aged college students. Using data from the College Student Experiences Questionnaire (Pace, 1990), the author examines this relationship for a random sample…

This study tested how name writing affects young children's emergent writing. Beginning with a group of 96 Dutch children ages 3 1/2-5, we selected more-advanced children who were producing strings of conventional letters but, apart from very few words, no correct or readable (invented) spellings (N = 35). All children recruited from…

This paper is based on a presentation given at National Council of Teachers of Mathematics (NCTM) in 2005 in Anaheim, California. It explicates the developmental stages of the child as posited by Piaget. The author then ties each of the stages to developmentally appropriate mathematics instruction. The implications in terms of not imposing…

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families…

We propose an integration of aspects of several developmental and systems of beliefs models of personal epistemology. Qualitatively different positions, including realism, dogmatism, skepticism, and rationalism, are characterized according to individuals' beliefs across three dimensions in a model of epistemic and ontological cognition. This model…

The aim of this study was to explore the extent to which the characteristics of two teaching interventions can bring about cognitive progress in preschoolers with regard to the factors rolling friction depends on, when it is applied to an object that is freely rolling on a horizontal surface. The study was conducted in three phases: pre-test,…

Children's cognitive skills change substantially from the time they enter school at about the age of five to when they graduate from high school a dozen years later. Some changes can be attributed to the school curriculum, but others are part of children's developmental evolution as they mature and interact with the world. Rather than reviewing…

This study examined the cognitive effects of an educational early childhood television program in Turkey that was designed to enhance basic cognitive skills and socio-emotional development of 5-year-old children. The program targeted children with low socioeconomic status who had limited access to formal preschool education. The program was…

Previous studies have found that children have difficulty solving proportional reasoning problems involving discrete units until 10 to 12 years of age, but can solve parallel problems involving continuous quantities by 6 years of age. The present studies examine where children go wrong in processing proportions that involve discrete quantities. A…

The present research identifies an anomaly in sociocognitive development, whereby younger children (8 and 9 years) outperform their older counterparts (10 and 11 years) in a basic categorization task in which the acknowledgment of racial difference facilitates performance. Though older children exhibit superior performance on a race-neutral…

Theoretical perspectives on spelling characterize development as a progression through qualitatively different phases or as a process of more or less continuous growth. This study investigated the potential utility of a different perspective, the overlapping-wave model, for characterizing spelling development (Rittle-Johnson & Siegler, 1999). In…

The emergence of the incorporation of culture into EFL education is a growing trend in Taiwan. The purpose of the study was to examine: (1) the effects of the ethnographic interview project on Taiwanese students' cognitive development in understanding native English speakers and their cultures; (2) changes in students' self-awareness and…

"Numeracy," so-called on analogy with literacy, is essential for making health and other social judgments in everyday life [Reyna, V. F., & Brainerd, C. J. (in press). The importance of mathematics in health and human judgment: Numeracy, risk communication, and medical decision making. "Learning and Individual Differences."]. Recent research on…
