In secondary school philosophy classes students learn to reason critically about social and scientific issues. This study examined the effects of a whole-class, teacher-led philosophy classroom dialogue intervention on students’ value-loaded critical thinking. Value-loaded critical thinking is logically consistent, self-reflective reasoning focused on making moral value-judgments about what is right to believe or do. In a quasi-experimental study (N = 437 students) with a pre-test post-test design, we investigated whether engaging in classroom dialogues in which the teachers implemented five design principles for promoting value-loaded critical thinking and transfer thereof, positively affected students’ (n = 150) value-loaded critical thinking in transfer tasks. The results were compared to two comparison conditions: students (n = 149) who participated in regular teacher-led philosophy classroom dialogues and students (n = 145) who followed a regular 10th-grade curriculum without philosophy classes. Results showed that students in the intervention condition outperformed students in both comparison conditions on referring to moral values. Regarding critical reasoning, we only found significant effects compared to the students who followed the regular 10th-grade curriculum. Findings indicate that a specifically designed dialogic intervention can enhance students’ capacities in value-loaded critical thinking.
The topic of this paper is the constructivism-realism debate, construed as an example of the intrusion of philosophy into science. Against this intrusion I maintain that philosophical problems are not only different from scientific and practical ones. They are also problematic in themselves. That is why their import into our scientific and practical work only creates confusions that hinder us in our work. The aim of the paper is to show that the philosophical problems that create those confusions need a Wittgensteinian therapeutic treatment. The method of the paper consists in comparing what philosophers (or philosophising scientists) say we do with what we actually do. After giving an example of what happens when a rightly respected scientist starts philosophizing, the method is applied, first, to the relation between language and the world and, second, to the relation between theories and the world. In the first application a story about three umpires is used to distinguish language and discourse, between questions of meaning (of the words we use) and questions of truth (of the things we say). In the second application a comparison between maps and theories is used to show the difference between assessing the truth of descriptive statements and explanatory theories. The examples of the umpires and maps are introduced by Weick and in both cases I show that neither constructivist nor metaphysical realist conclusions follow.
Value-loaded critical thinking refers to a combination of critical thinking, moral value development and reflection. It is important to teach value-loaded critical thinking in secondary education and philosophy seems the pre-eminent subject to do so. This article describes the theoretical foundations of value-loaded critical thinking, its educational objectives, and what is known about effective teaching strategies. Value-loaded critical thinking is best taught in teacher-led philosophical dialogues. Four design principles summarize effective teaching strategies for teaching value-loaded critical thinking in dialogue: teachers should (1) explicitly address moral values in dialogue; (2) apply moral values to engaging or realistic examples; (3) promote critical reasoning about moral values; and (4) provide opportunities for reflection.It is important that secondary school students learn to reason critically about normative issues. Philosophy teachers can contribute to this educational objective by promoting value-loaded critical thinking during philosophical dialogues. Value-loaded critical thinking is critical and reflective reasoning focused on deciding what is the right thing to believe or to do (Frijters et al. 2008). This paper describes the theoretical foundations of value-loaded critical thinking and presents four design principles for promoting value-loaded critical thinking during philosophical dialogues. The four design principles are: teachers should explicitly address moral values in dialogue (1), apply moral values to engaging or realistic examples (2), promote critical reasoning about moral values (3), and provide opportunities for reflection (4). To provide authentic illustrations and practical suggestions for teachers, each design principle includes selected excerpts of classroom dialogues of 10th grade philosophy classes in Dutch.
