Using Problem Solving to Assess Young Children’s Mathematics Knowledge

Mathematics problem solving provides a means for obtaining a view of young children’s understanding of mathematics as they move through the early childhood concept development sequence. Assessment information can be obtained through observations and interviews as children develop problem solutions. Examples of preschool, kindergarten, and primary grade children’s approaches to problem solving are provided in the article. Prekindergarten and kindergarten age children discover problems during play. For example, they figure out how to use informal measurement to use construction materials such as unit blocks and Lego to build a desired building or make a desired object. Moldable materials such as clay and play dough provided shape experiences. The daily sequence of activities builds on their concept of time. Primary grade children solve adult- and child-generated problems. They may use manipulatives and/or drawings to generate problem solutions prior to using symbols and notation. Teacher and/or student devised rubrics can be used to guide evaluation.     

Software to Promote Young Children’s Growth in Literacy: A Comparison of Online and Offline Formats

The primary goal of this research was to extend our understanding of the strengths and weaknesses inherent in online and offline early literacy software programs designed for young learners. A taxonomy of reading skills was used to contrast online software with offline closed system (compact disc) based programs with respect to number of skills taught, quality of instruction and scaffolding during instruction. Overall, online programs were more comprehensive and provided instruction for more skills than offline software at either the Kindergarten or Grade 1 level. However, offline programs demonstrated some developmentally appropriate selectivity in skills trained. Quality of instruction was variable within and across all programs. Scaffolding of instruction was also variable and surprisingly few programs, either online or offline, provided automatic movement across levels of difficulty. These outcomes have important implications for the selection of instructional materials by parents and educators involved in early literacy instruction and also for future software design.     

Children Explain the Rainbow: Using Young Children’s Ideas to Guide Science Curricula

This study examines young children’s ideas about natural science phenomena and explores possibilities in starting investigations in kindergarten from their ideas. Given the possibilities inherent in how young children make sense of their experiences, we believe it is critical to take children’s perspectives into consideration when designing any activities, and ideally, to design activities from their perspectives and understandings. Specifically, this research focuses on 5- and 6-year old children’s explanations of rainbows, and there are three main findings. First, our analysis demonstrates that opportunities to discuss their ideas revealed children’s different perceptions of the phenomena of rainbows. Secondly, this research emphasizes that peer-to-peer interaction in the co-construction of science concepts provided support to the children to learn from, and with, each other. Third, children’s initial explanations provided the teacher-researcher (second author) with a starting point to scaffold her teaching from. Although rainbows are quite an abstract topic to try to reproduce in the classroom, the children demonstrated their often sophisticated understandings of natural science phenomena, as well as their creative ideas as related to rainbows. In order to foster an appreciation of themes in natural science, it is crucial to build from what children already know and can do, and to use these emergent theories and considerations in designing curriculum. Thus, we draw implications for the importance of teaching science at the early childhood level and for using children’s ideas as starting points in planning instruction.

Number Knowledge and Young Children’s Ability to Measure Length

Research Findings: In this research we explore the relationship between young children’s number knowledge and their measurement of length. First, we examined 4- to 5-year-olds’ (kindergartners’) understanding of and preference for using standard or nonstandard units to measure length. Second, we investigated whether the following tasks were related to children’s understanding of using standard (i.e., rulers) and nonstandard (i.e., blocks) units to measure length: (a) counting and written number identification knowledge, (b) symbolic or nonsymbolic number magnitude comparison ability, and (c) approximate number line estimation ability. Third, we examined whether understanding these number tasks predicted understanding how to measure length for both standard and nonstandard units. Our results show that young children prefer to use standard units of measurement when given a choice, and some of these children use a ruler correctly. Our results also show an important relationship between children’s understandings of numbers and measurement. Practice or Policy: Given children’s preference for rulers, introducing both nonstandard and standard units in early learning settings concurrently rather than consecutively is recommended for practice.     

Young Children’s Ability to Produce Valid and Relevant Counter-Arguments

In collaborative problem solving, children produce and evaluate arguments for proposals. We investigated whether 3- and 5-year-olds (N = 192) can produce and evaluate arguments against those arguments (i.e., counter-arguments). In Study 1, each child within a peer dyad was privately given a reason to prefer one over another solution to a task. One child, however, was given further information that would refute the reasoning of their partner. Five-year-olds, but not 3-year-olds, identified and produced valid and relevant counter-arguments. In Study 2, 3-year-olds were given discourse training (discourse that contrasted valid and invalid counter-arguments) and then given the same problem-solving tasks. After training, 3-year-olds could also identify and produce valid and relevant counter-arguments. Thus, participating in discourse about reasons facilitates children’s counter-argumentation.     

Mothers’ Job Loss and Their Sensitivity to Young Children’s Development

As the economy diversifies and stratifies, more mothers of young children experience job instability. To advance understanding of the implications of this trend, this study examines the role of job instability in maternal sensitivity, an important component of child development, during their children’s first 3 years of life. Structural equation models with longitudinal multimethod data from the NICHD Study of Early Child Care and Youth Development (n = 1,211; 1991–1994) revealed that mothers’ involuntary job loss, but not other job transitions, was negatively associated with sensitivity. This association was most pronounced among mothers with less education. Mediation analyses found that the association was explained by changes in family income and maternal depression, pointing to policy-relevant mechanisms for reducing inequalities among children.     

A Phonetic Study of Young Children’s Speech

Abstract. The author examined the effectiveness of training in symbolic logic for improving students' deductive reasoning. A total of 116 undergraduate students (approximately equal numbers of men and women) enrolled in 1st-year university philosophy courses in symbolic logic participated in 2 studies. In both studies, students completed booklets of categorical and conditional syllogisms at the beginning of the course and again at the end of the course. In Study 2, students also specified their reasoning strategies. Results indicated that students' strategies changed with training (students increased their use of mental models and mental rules with categorical and conditional syllogisms, respectively), but their reasoning performance improved only moderately. The educational implications of these results are explored.     

Investigating Young Children’s Perceptions of Body Size and Healthy Habits

Attitudes and biases toward body size perceived as fat and body size perceived as thin are present in young children (Cramer and Steinwert in J Appl Dev Psychol 19(3):429–451, 1998; Worobey and Worobey in Body Image 11:171–174, 2014). However, the information children have regarding body size and ways to modify body size might not be accurate, which could lead to negative health outcomes. To collect information for developing strategies to prevent such health outcomes, this study explored children’s perceptions towards body size, factors they believed contribute to body size differences, and strategies they indicated as necessary to make changes in body size. Forty-eight children from 1st grade and 3rd grade were interviewed. The majority of children were aware that the quality and quantity of food influences body size. They expressed similar strategies to change body size; however, some of their strategies were extremely unhealthy. Children in this group prefer an average body size rather than the thinnest size body from the selections presented. Information obtained from the study demonstrated the importance of guiding children to establish appropriate eating and healthy habits that might ultimately prevent extreme behaviors and health problems. It is crucial to help all children realize the importance of maintaining a healthy body rather than an overly thin body.     

Nature of Interactions Among Young Children and Adult Caregivers in a Children’s Museum

This naturalistic, qualitative study examines the nature of child- and adult-led interactions in a children’s museum. Using dialogic learning as a theoretical framework, the study examines how children and adults engage in interactions while learning at a museum. Findings suggest that children and adults are almost equally likely to lead interactions; however, most child-led interactions are qualitatively different from adult-led interactions. Children are more likely to show-and-tell about their experiences and learn by asking questions and commenting about their play. Adults are more likely to teach by telling, prompting, and reporting a child’s activities. Children and adults also are equally engage in pretend play during their interactions. Leveraging these findings, recommendations are made for museum exhibit space design.     

Using DNA From Mothers and Children to Study Parental Investment in Children’s Educational Attainment

This study tested implications of new genetic discoveries for understanding the association between parental investment and children’s educational attainment. A novel design matched genetic data from 860 British mothers and their children with home-visit measures of parenting: the E-Risk Study. Three findings emerged. First, both mothers’ and children’s education-associated genetics, summarized in a genome-wide polygenic score, were associated with parenting—a gene–environment correlation. Second, accounting for genetic influences slightly reduced associations between parenting and children’s attainment—indicating some genetic confounding. Third, mothers’ genetics were associated with children’s attainment over and above children's own genetics, via cognitively stimulating parenting—an environmentally mediated effect. Findings imply that, when interpreting parents’ effects on children, environmentalists must consider genetic transmission, but geneticists must also consider environmental transmission.     

Supporting Young Children’s Vocabulary Growth: The Challenges, the Benefits, and Evidence-Based Strategies

The complexity of words makes vocabulary development a multi-faceted process that presents challenges to early childhood educators, offers benefits to young learners, and must be supported through evidence-based strategies. All students, regardless of socio-economic status or background, need to make significant gains in receptive and expressive vocabulary at home and at school each year in order to support their growth in literacy. Students from low socioeconomic backgrounds and those students who speak English as a second language are particularly at risk of failing to make proficient vocabulary gains. The most effective way for early childhood educators to enhance the vocabulary development of all students is to implement evidence-based strategies for teaching vocabulary. A key finding in the research is that young children need to be actively engaged in vocabulary development if they are to remember new words and begin to grasp the multiple, nuanced meanings of words. Other effective vocabulary instruction practices include meaningful repetition; combining the enactive, iconic, and symbolic modes; and reading aloud in a dialogic style. In light of the trend in the research data that links the child’s vocabulary level to gains in reading comprehension, early childhood educators have a special obligation to teach vocabulary more effectively.     

Teachers’ Conceptions of Gifted and Talented Young Children

Efforts by schools to cater more adequately for highly able students necessitate a shared understanding regarding the gifted and talented. This research aims to ascertain the qualitatively different ways in which teachers identify and describe gifted and talented children. It examines the variety of conceptions of giftedness held by teachers and analyses the patterns and inconsistencies among them. Initial findings of the study, conducted with 16 early childhood teachers (two male and 14 female), are reported. A qualitative phenomenographic research design was adopted because of its focus on revealing individual understandings (conceptions). These results show that teachers understand giftedness as a series of conceptions, namely excellence, potential, rarity, behaviour, innate ability, motivation and asynchrony. These are discussed with reference to existing theories and pertinent research. Results represent the initial findings of an ongoing major research project.     

Nurturing Students’ Critical Knowledge Using Technology-enhanced Scaffolding Strategies in Science Education

Critique is central to the development of scientific knowledge. From a cognitive perspective, critique can be used to enhance understanding. From a social perspective, critique serves to maintain the standards of a professional field. In science education, it is of tremendous value to diagnose and nurture students’ critical knowledge. How students develop and apply criteria for critique, however, remains unclear. What factors influence students’ performance of critique, and how can educators incorporate technology-enhanced scaffolding strategies to help diagnose and nurture students’ critical knowledge? In this paper, I define critical knowledge as the criteria people use to evaluate other knowledge, the ability to use these criteria across contexts, and the reflective understanding of such processes. Building on existing literature, I develop a conceptual framework that describes the components and processes involved in a critique activity. Using this framework, I discuss the application of technology-enhanced scaffolding strategies to facilitate critique activities in science classrooms.
