This article reports on a classroom teaching experiment that engaged a group of high school students in designing sampling simulations within a computer microworld. The simulation-design activities aimed to foster students' abilities to conceive of contextual situations as stochastic experiments, and to engage them with the logic of hypothesis…

This study examines the effectiveness of classroom experiments conducted before the relevant theories were taught. The experiments were used to provide students with first-hand experience of decision-making under various rivalry settings and to demonstrate several key predictions of oligopoly models. Statistical methods were used to analyze the…

Collaboration scripts have repeatedly been implemented in Computer-Supported Collaborative Learning (CSCL) to facilitate collaboration processes and individual learning. However, finding the right degree of structure is a subtle design task: scripts that are too rigid may impair self-regulation and hinder learning; scripts that are too flexible…

Although temperament and motivation both reflect individual differences in what is perceived as rewarding or threatening, and what is to be approached and what avoided, respectively, we know rather little about how they are connected in educational settings. In this study, we examined how different aspects of temperament (reward and punishment…

In three experiments, I tested for the presence of the naming capability, the participants' drawing responses of the stimuli learned in the absence of the visual stimulus, and the participants' comprehension of texts with and without pictures present. In Experiment 1, I tested for the presence of naming and the drawing responses for the stimuli…

The present work investigates whether and how morphological decomposition processes bias the reading of Hebrew heterophonic homographs, i.e., unique orthographic patterns that are associated with two separate phonological, semantic entities depicted by means of two morphological structures (linear and nonlinear). In order to reveal the nature of…

The problem of demonstrative behavior is very topical among teenagers and this issue has become the subject of systematic scientific research. Demonstrative manifestations in adolescents disrupt the favorable socialization; therefore, understanding, prevention and correction of demonstrative behavior at this age is relevant and requires special…

Language plays a key role in statistics and, by extension, in statistics education. Enculturating students into the practice of statistics requires preparing them to communicate results of data analysis. Statistical argumentation is one way of providing structure to facilitate discourse in the statistics classroom. In this study, a teaching…

In a series of experiments, we tested a recently proposed hypothesis stating that the degree of alignment between the form of a mental representation resulting from learning with a particular visualization format and the specific requirements of a learning task determines learning performance (task-appropriateness). Groups of participants were…

Empirical arguments rely on examples without necessarily addressing all cases. Students should be skeptical of empirical evidence and should seek more secure arguments for generalizations, such as those that explain why a generalization is true for all cases. Generalizing on the basis of patterns in data is an important mathematical practice;…

Pre-service teachers need to develop habits of mind that allow them to grow as new teachers. This article describes an elementary mathematics methods course in which teaching as an experiment was used a framework for pre-service teachers to participate in action research by developing learning goals, observing and analyzing student thinking,…

The present experimental study explores whether teachers are "clever" thinkers when assessing students' credibility, i.e., saving cognitive resources when possible and making accurate judgments. Participants were asked to decide whether student statements about using unfair means during a test were true or deceptive. First, participants'…

This article summarizes a conceptual framework and simple mathematical methods of estimating the probability that one event was a necessary cause of another, as interpreted by lawmakers. We show that the fusion of observational and experimental data can yield informative bounds that, under certain circumstances, meet legal criteria of causation.…

Given that a user interface interacts with users, a critical factor to be considered in improving the usability of an e-learning user interface is user-friendliness. Affordances enable users to more easily approach and engage in learning tasks because they strengthen positive, activating emotions. However, most studies on affordances limit…

In this article, the author presents an asymmetric version of the familiar public goods classroom experiment, in which some players are given more tokens to invest than others, and players collectively decide whether to divide the return to the group investment asymmetrically as well. The asymmetry between players raises normative issues about…
