Teaching to support students' sense-making is challenging. It requires continuous, context-dependent decision-making about which student ideas to pursue, when, how, and why. This paper presents a single case study of an experienced teacher, Nadine, as an illustrative case in order to provide a rich description of this teacher's decisional…

A major challenge in the process of innovation is to generate quality products that are original as well as feasible, because these features are associated with contradictory cognitive thought processes. This study investigated whether opportunities to engage in an idea generation, selection, and subsequent refinement with a simultaneous focus on…

In a dynamic labor market, it is important to help people combine information and generate creative solutions to cope with complex career challenges. In the present research, we apply the theory of information structure to creative career idea generation and hypothesize that flat information structures--that is, structures in which the information…

Engineering design has been central to technology education. Currently, online collaborative platforms for designers are widely used as digital forms of an engineer's notebook. However, traditional forms are still valued as the medium of engineering design during the conceptual phase of design since a paper notebook and pen or pencil allow…

Even after research-based instruction, students who demonstrate the ability to assemble relevant conceptual knowledge on one physics question may have difficulty assembling that same knowledge on a closely related problem. Recent research has suggested that reflexive, bottom-up reasoning processes seemingly unrelated to the physics concepts…

This qualitative study aimed to examine: (1) the manner in which kindergarten children and first graders make sense of the term "area" regarding optimization problems; (2) how this manner is manifested in their decision-making and "STEAM" (science, technology, engineering, art and math) skills; and (3) how kindergarten children…

Algebraic thinking and strategy flexibility are essential to advanced mathematical thinking. Early algebra instruction uses 'missing-operand' problems (e.g., x - 7 = 2) solvable via two typical strategies: (1) direct retrieval of arithmetic facts (e.g., 9 - 7 = 2) and (2) performance of the inverse operation (e.g., 2 + 7 = 9). The current study…

This paper outlines a theoretical paradigm for distinguishing thinking, knowing and believing. A new taxonomy is presented for categorizing levels of knowing and outlines a structure of justification for each level. The paper discusses and explains the importance of such distinctions in decision making and thinking in general.

We conducted three experiments to study the role of instrumental (e.g. "knife-bread") and categorical (e.g. "cake-bread") relations in the development of conceptual organization with a priming paradigm, by varying the nature of the task (naming--Experiment 1--or categorical decision--Experiments 2 and 3). The participants were 5-, 7- and…

Children's ability to exercise selective trust is crucial for the development of their knowledge and successful socialization. For speakers of some languages, evidentials, which are grammatical source-of-knowledge markers, could provide valuable support of these processes. Focusing on Bulgarian, this chapter situates children's use of evidentials…

Framing effects are said to occur when equivalent frames lead to different choices. However, the equivalence in question has been incompletely conceptualized. In a new normative analysis of framing effects, we complete the conceptualization by introducing the notion of information equivalence. Information equivalence obtains when no…

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within…

Article investigated the extent it is both possible and desirable to instruct others in moral judgment. (Editor/RK)

The effect of set (to integrate or differentiate), characterization and conceptual structure on comprehension of a social situation was studied with a sample of 83 psychology students. Subjects judged groups, read stories and completed comprehension tests. Evidence provides support for the assumption that impressions affect one's comprehension of…

During the development or assessment of drug education programs, many individuals insist on the avoidance of "moralizing". An awareness of moral principles, rules and values is a necessary criterion to rational thought processes. This paper attempts to clarify these philosophical issues in a manner which can be put into practice in many types of…
