Critical thinking (CT) is purposeful, self-regulatory judgment that results in interpretation, analysis, evaluation, and inference, as well as explanations of the considerations on which that judgment is based. This article summarizes the available empirical evidence on the impact of instruction on the development and enhancement of critical thinking skills and dispositions and student achievement. The review includes 341 effects sizes drawn from quasi-or true-experimental studies that used standardized measures of CT as outcome variables. The weighted random effects mean effect size (g+) was 0.30 (p < .001). The collection was heterogeneous (p < .001). Results demonstrate that there are effective strategies for teaching CT skills, both generic and content specific, and CT dispositions, at all educational levels and across all disciplinary areas. Notably, the opportunity for dialogue, the exposure of students to authentic or situated problems and examples, and mentoring had positive effects on CT skills.

Background. Simulations of complex systems have a long history of use for the study and promotion of systems thinking, yet more can be done in identifying games that promote development of systems thinking. Aim. This study is an exploration of the hypothesis that FATE OF THE WORLD, a challenging and complex climate change simulation, can promote systems thinking about climate change. Questions. This article analyzes players’ engagement with FATE OF THE WORLD using three key questions: 1. In what ways does the game support thinking about climate change as a complex system? 2. Does the game correspond to players’ a priori model of climate change? 3. How do players relate to FATE as an artifact they embrace, critique, and tinker with? Method. 33 participants were matched into control and test groups, and experimental participants were assigned to play a full game scenario of FATE OF THE WORLD. Experimental and control groups were compared using pre-and-post intervention concept maps. Post interviews were conducted with the test group. Results. Concept maps revealed statistically significant differences between the control and test groups. Interviews revealed diversity in learning outcomes and the ways in which acceptance of the game’s model of climate change influenced learning. Conclusions. FATE serves as proof-of-concept for the power of complex simulations to promote systems thinking as well as in-depth reflection on key social challenges. However, simulations like FATE are unlikely to serve well as stand-alone educational tools, which highlights the importance of effective teaching to accompany the game.

In this essay, Bruce Maxwell, David Waddington, Kevin McDonough, Andrée‐Anne Cormier, and Marina Schwimmer compare two competing approaches to social integration policy, Multiculturalism and Interculturalism, from the perspective of the issue of the state funding and regulation of conservative religious schools. After identifying the key differences between Interculturalism and Multiculturalism, as well as their many similarities, the authors present an explanatory analysis of this intractable policy challenge. Conservative religious schooling, they argue, tests a conceptual tension inherent in Multiculturalism between respect for group diversity and autonomy, on the one hand, and the ideal of intercultural citizenship, on the other. Taking as a case study Québec's education system and, in particular, recent curricular innovations aimed at helping young people acquire the capabilities of intercultural citizenship, the authors illustrate how Interculturalism signals a compelling way forward in the effort to overcome the political dilemma of conservative religious schooling.
