A key learning outcome in problem-solving domains is the development of flexible knowledge, where learners know multiple strategies and adaptively choose efficient strategies. Two interventions hypothesized to improve flexibility in problem solving were experimentally evaluated: prompts to discover multiple strategies and direct instruction on…

This study examines ways of approaching deductive reasoning of people involved in mathematics education and/or logic. The data source includes 21 individual semi-structured interviews. The data analysis reveals two different approaches. One approach refers to deductive reasoning as a systematic step-by-step manner for solving problems, both in…

Cochise College, Cochise County, and the Cochise Community Foundation partnered to create the Cochise County Quality of Life Index--the first to be developed in Arizona. The project brought together stakeholders to address shared problems in new ways, based on non-traditional partnerships. The college's Center for Economic Research provided…

Continuity in conflict behaviors from (a) adolescents' behavior with parents and their behavior with romantic partners and (b) from parents' marriage to adolescents' romantic relationships were examined in a sample of 58 mother-father-adolescent families and the adolescents' romantic partners. The social relations model was used to analyze…

The current study evaluated the effects of tokens delivered on differential reinforcement of zero-rate behavior (DRO) schedules or noncontingently on tic suppression in 4 children with tics. Tic frequency was lower in 3 of 4 children when tokens were delivered contingent on the absence of tics than when tokens were delivered noncontingently.…

This study examined achievement patterns of middle school students enrolled in Standards-based curricula, in particular those curricula that were funded from a solicitation of proposals through the National Science Foundation (NSF) in the early 1990s (NSF RFP 91-100). Approximately 1400 middle-grades students who had used either the Connected…

School-wide positive behavior support (SWPBS) has been proposed as a proactive and preventive method to reduce problematic behavior in schools. Under this approach, educators and administrators seek to create a school environment that fosters prosocial behavior and attempts to systematically deter problem behaviors before they happen. To date, the…

A gasp-provoking amount of money will be donated and bequeathed to the nation's colleges over the next two generations. The total amount of college endowments is about $411.2-billion, according to the National Association of College and University Business Officers, and it can be expected to double, if not triple, in size over the next several…

The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing…

This article uses diagrams that help the observer see how solutions of the wave equation and heat conduction equation are obtained. The analytical approach cannot necessarily show the mechanisms of the key to the solution without transforming the differential equation into a more convenient form by separation of variables. The visual clues based…

Resampling methods including randomization test, cross-validation, the jackknife and the bootstrap are widely employed in the research areas of natural science, engineering and medicine, but they lack appreciation in educational research. The purpose of the present review is to revisit and highlight the key principles and developments of…

In a student production of "Dracula" at Texas A&M University some years ago, the final scene was exceptionally dramatic. One actor stabbed another, who was playing the vampire, in the chest with a real knife. A volunteer director from the community, who was assisting the drama club, had decided that the scene required the actual weapon, not the…

Whereas product-oriented worked examples only present a problem solution, process-oriented worked examples additionally explain the rationale behind the presented solution. Given the importance of understanding this rationale for attaining transfer, process-oriented worked examples would be expected to result in more efficient transfer. However, a…

The present study examined the timing of behavioral autonomy transitions in two same-aged cohorts of East German adolescents assessed in 1991 and 1996. An earlier timing of autonomy privileges was associated with higher deviant behavior. A later timing of autonomy privileges and responsibilities was linked to structural constraints, specifically,…

Many students with Attention-Deficit Hyperactivity Disorder (ADHD) present with behavioral problems that are particularly evident in out-of-class settings (in the lunch room, on the playground, during field trips and special assemblies, etc). Barkley's (1997) technique has been known to help parents handle ADHD children's behaviors in out-of-home…
