We explored the possibility of publication bias in the sleep and explicit motor sequence learning literature by applying precision effect test (PET) and precision effect test with standard errors (PEESE) weighted regression analyses to the 88 effect sizes from a recent comprehensive literature review (Pan & Rickard, 2015). Basic PET analysis…

Action research has been described as "designing the plane while flying it" (Herr & Anderson, 2005, p. 69). A black box documented the researcher's decisions while facilitating leadership development sessions with teacher leaders. Ten process folio steps informed the study through six iterations. Planning steps included a design…

Design research studies provide significant opportunities to study new innovations and approaches and how they affect the forms of learning in complex classroom ecologies. This paper reports on a two-week long design research study with twelve 2nd through 4th graders using curricular materials and a tablet-based diagnostic assessment system, both…

A hierarchical learning task was designed and developed in accordance with an instructional design model to study questions concerning task structure, sequencing, and other instructional design variables. To provide control and generality, the learning task was based on an entirely imaginary science. (RH)

The criterion problem in the neoPiagetian cognitive-developmental literature is reviewed. This problem has provoked debate in the context of three empirical questions: concept age norms, concept training effects, and concept invariant sequences. It is argued that only the question of invaniant sequences in same-stage concepts is theoretically…

Two hundred first grade children participated in an experimental program involving innovative curricula and instructional techniques. A pretest-posttest method of instruction, employing sequenced and structured learning activities, enabled each child to progress at an individual rate and was supplemented by a readiness program. Evaluation of the…
