In organizational anarchies (i.e., public institutions) decisions are typically made by oversight or flight. Decision makers and choice opportunities exist simultaneously but on separate tracks resulting in few problems being solved. This paper presents the findings of a study surveying current literature on organizational anarchy as well as…

Spaced and interleaved practices have been identified as effective learning strategies which sometimes are conflated as a single strategy and at other times treated as distinct. Learning sessions in which studying information or practicing problems are spaced in time with rest-from-deliberate-learning periods between sessions generally result in…

We performed a meta-analysis of dual-task experiments to assess the robustness of the effects of conducting working memory secondary tasks on arithmetic performance. Four hundred effect sizes from 21 studies from 1,049 participants were analyzed across a variety of specifications. Results revealed that increases in working memory load resulted in…

This paper reviews the literature relating to the factors that contribute to the difficulties in learning of computer programming. Programming has been a difficult subject to learn and master even at the early stage of education. It has been a global problem and continues to worsen at the local level. Although, there are many education tools…

Simulation-based learning offers a wide range of opportunities to practice complex skills in higher education and to implement different types of scaffolding to facilitate effective learning. This meta-analysis includes 145 empirical studies and investigates the effectiveness of different scaffolding types and technology in simulation-based…

Mathematical discussions in which students compare alternative solutions to a problem can be powerful modes for students to engage and refine their misconceptions into conceptual understanding, as well as to develop understanding of the mathematics underlying common algorithms. At the same time, these discussions are challenging to lead…

Launched in June 2016, the Smithsonian Learning Lab (SLL) provides access to the digital resources from across the Smithsonian's 19 museums, 9 major research centers, and the National Zoo, to be used as real-world learning experiences. It is designed to aid students in building lasting knowledge and critical skills that take learners from simply…

Reviews procedures followed during traditional organizational change and identifies factors that lead to increased intrinsic motivation. Topics discussed include problem solving, level of challenge, competence, people as information processors, curiosity, task complexity, the need for organization, and choice in degree of control.

Discusses five research areas offering guidance to people concerned about teaching problem solving in elementary schools. Areas are (1) components of problem difficulty; (2) the contribution of reading difficulties to problem-solving deficiencies; (3) characteristics of successful problem solvers; (4) children's use of problem-solving techniques…

A review of research and theory on cognitive processes and their relationship to instructional technique since the early 1970s looks at the contributions of schema theory and artificial intelligence and their instructional implications, including cognitive load theory, worked examples for learning problem solving, and physical vs. mental…

A procedural model, designed to assist practitioners in working with students with learning problems, targets three stages of the diagnostic-prescriptive teaching process: (1) defining the problem; (2) assessing potentially causal mismatches between child, task, and setting; and (3) intervening by eliminating or minimizing mismatches.

Presents findings from five studies measuring students' attitudes towards mathematics, perception of performance, perception of the importance of mathematical problem solving, and perception of problem difficulty. The interaction of affect and cognition and the implications for assessing and teaching mathematical problem solving to students with…

In assessing the quality of science teaching for an effort such as the National Assessment of Educational Progress (NAEP), it is important to understand what is meant by scientific thinking--the search for explanations. Instruction should involve higher-order cognitive skill development, but it is difficult to measure reasoning and understanding…
