Randomized experiments can provide key insights for improving educational technologies, but many students may experience conditions associated with inferior learning outcomes in these experiments. Multiarmed bandit (MAB) algorithms can address this issue by accumulating evidence from the experiment as it runs and modifying the experimental design…

This study used design experiments, specifically micro-cycle teaching experiments (MTE) as a catalyst for practice-based professional development. The MTE incorporated research-based characteristics of effective professional development: it was embedded in the teachers' daily work of planning and enacting lessons, co-constructed with the…

Predicting the success or failure of a student in a course or program is a problem that has recently been addressed using data mining techniques. In this paper we evaluate some of the most popular classification and regression algorithms on this problem. We address two problems: prediction of approval/failure and prediction of grade. The former is…

Previous research has largely documented that socioeconomic status (SES) is a strong and consistent predictor of pupils' school performance in several countries. In this research, we argue that children internalize the SES achievement gap in the form of a lower/higher sense of school self-efficacy. In two studies, teenaged students' (Study 1) and…

This paper explores the ways students perceive the transfer of learned knowledge to new situations -- often a surprisingly difficult prospect. The novel aspect compared to the traditional transfer studies is that the learning phase is not a part of the experiment itself. The intention was only to activate acquired knowledge relevant to the…

This teaching experiment provided students with continuous engagement in a problem-solving based instructional approach during one mathematics unit. Three sections of sixth-grade mathematics were sampled from a school in Florida, U.S.A. and one section was randomly assigned to experience teaching through problem solving. Students' problem-solving…

The objective of this research is to validate the algorithm of learning effort which is an indicator of a new real-time and non-interfering based diagnostic technique. IC3 Mentor, the adaptive e-learning platform fulfilling the requirements of intelligent tutor system, was applied to 165 university students. The learning records of the subjects…

This study was conducted to determine if raters would use a single policy for determining the beauty of paintings and to demonstrate the JAN technique in an experiment where the predictors first had to be hypothesized and then a quantified measure ascribed to each. (Author/RK)

The mathematical solution to a Piagetian experiment involving topological concepts reported in a recent book is labeled as a sham. The correct solution is given and discussed. (MP)

The authors describe a one-quarter, undergraduate teacher education experience that involved a high level of personal freedom and synergy in an attempt to develop humanistic teachers. Twenty-three juniors and seniors were involved in the program, which took the form of an unstructured block of courses in mathematics, science, and social studies.…

This paper reports on an experiment designed to investigate the effect of structural and linguistic variables on level of difficulty in solving arithmetic word problems. Identification of such variables is intended to assist curriculum writers in preparing exercises at a specified level of difficulty for students at various age levels. The study…

This report summarizes the principal findings for the O.E.O. experiment in performance contracting. The report emphasizes major results and conclusions to date. It is divided into (1) description of the experiment, in which the goal is outlined; (2) description of the technology company programs, curriculum and materials, and overviews of…
