Much of the research on the development of professional noticing expertise has focused on prospective teachers. We contend that we must investigate practicing teachers as well, and in particular practicing secondary teachers, because they bring with them years of teaching experience and are situated in unique contexts. Hence we studied the…

This paper contributes to the theory and evidence that mathematical cognition is embodied. Drawing on the practices of primary teachers in South Africa engaged in a longitudinal research and development project -- Wits Maths Connect--Primary -- we report on aspects of lessons aimed at developing number sense through whole-class teacher-learner…

The ability to recognize temporal patterns and position events in time emerges during the preschool years and is refined in middle childhood. This study explored individual differences in temporal cognition in relation to verbal and nonverbal abilities. Children (30 boys, 32 girls; M[subscript age] = 8;2, age range = 6;0-10;8) completed 3…

This study designed learning activity to enhance students' cognitive processes. Students could learn in class and then apply and analyze new knowledge to solve daily life problems by taking pictures of learning objects in familiar authentic context, describing them, and sharing their homework with peers. This study carried out an experiment and it…

We are so used to accept new technologies being the driver of change and innovation in human computer interfaces (HCI). In our research we focus on the development of innovations as a design process--or design, for short. We also refer to the entire process of creating innovations and putting them to use as "cognitive processes"--or…

A model of human information processing is summarized and discussed in terms of the implications of the model and its associated technologies for curriculum research and development. Description of the model focuses on its input and output systems and its memory systems, i.e., long-term memory (LTM). Semantic networks are described as a…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

This paper explores what we can learn from research that early cognitive processes support the development of children's mathematics skills. The role of two cognitive processes in working memory in the development of early mathematics was investigated: executive functions (EF) and visual-spatial (VS) ability. Children's mathematical skills were…

Mathematical calculations are an important part of chemistry. Those problems are difficult for students, especially if the task is set with a limiting reactant. The aim of this study was development of a Procedure for evaluation of cognitive complexity of the Stoichiometric Tasks with a Limiting Reactant. The procedure created included an…

This longitudinal study aimed to determine changes in students' predictive reasoning across one year. Forty-four Australian students predicted future temperatures from a table of maximum monthly temperatures, explained their predictive strategies, and represented the data at two time points: Grade 3 and 4. Responses were analysed using a…

Relevance of this article are questions of the differentiated approach in a specification of the purposes, tasks, contents and ways of the organization of teaching and educational process to training and formations of key competences of students on the basis of accounting of individual abilities and requirements. The purpose of article consists in…

This symposium report on current child development research in Germany includes abstracts from papers presented at the biennial meeting of SRCD, April 1975, and a short overview of the history and present status of developmental research and training in Germany. According to this overview, developmental theory and empirical research, which had…

The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

The aim of this study is revealing the strategies used by 5th-grade students in comparing fractions. In line with this purpose the study is based on qualitative research. Participants of the study conducted with convenient sampling method are seventy 5th-grade students. The students have been asked six questions which necessitate comparison of…

Centrally concerned with design, educational technology involves making the best possible decisions for action given a particular set of circumstances, with a body of knowledge or instructional theory for guidance. More work is needed to aid educational technologists in the three tasks of building instructional theory, developing techniques for…
