Establishing enabling conditions to develop critical thinking skills: a case of innovative curriculum design in Environmental Science

This paper considers a curriculum design motivated by a desire to explore more valid pedagogical approaches that foster critical thinking skills among students engaged in an Environmental Science course in South Africa, focussing specifically on the topic of Citizen Science. Fifty-three under graduate students were involved in the course, which was run over a two week period. Data were generated from several sources, including individual student evaluations, a focus group discussion, lecturer reflections and summative assessment results. During the course, the development of critical thinking skills was scaffolded by different thinking approaches to the possibilities and problematics of student-selected case studies, followed by a collaborative re-examining of ‘what is known’ about Citizen Science. Spiralling engagement with various resources harnessed the diversity of the class, as they drew on their personal and disciplinary backgrounds. The insights highlight possibilities for alternative higher education teaching models for emerging subjects such as Environmental Science, where the competencies required of graduates, such as critical thinking and coping with uncertainty, differ significantly from traditional ‘science’ competencies, and therefore require a departure from traditional teaching methods.

Providing vertical coherence in explanations and promoting reasoning across levels of biological organization when teaching evolution

Students' explanations of biological phenomena are frequently characterized by disconnects between levels and confusion of levels. The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized, pre–post-test design study. Students in the experimental group engaged in a lab activity focused on artificial selection and designed to demonstrate how selection affects both phenotypes and genotypes. In contrast, the lab activity in the comparison group focused on phenotype alone. Data sources for the study included pre-tests of basic concepts in genetics and evolution and two post-test items requiring the students to reproduce and apply their knowledge about artificial selection. The findings indicated that the lab activity which allowed students to explore the interplay between different levels, provided vertical coherence and enhanced students’ ability to explain evolutionary change in both reproduction and transfer items. In contrast, the lab activity in the comparison group failed to do so, and most students did not improve their ability to explain evolutionary change. Implications for instruction and recommendations for further research are discussed in light of these findings.

论青少年创新思维的家庭教育

家庭作为社会活动组织的重要细胞和青少年生存发展的重要空间，历来承担着社会教育活动的重要功能。创新教育作为现代社会教育的重要内容与特征，其核心就在于创新思维教育。家庭教育应该成为青少年创新思维教育的重要领域。社会时代的要求、现代家庭结构的变化及其作为教育对象的青少年自身状况的变化规定了创新思维能力素质的培养、创造性生活技能的培养和创新心理素质的教育。这三者构成了青少年创新思维家庭教育活动的基本内容。在对青少年进行创新思维家庭教育活动过程中必须坚持民主宽容性教育、兴趣性教育、生活化情景教育、早期教育和开放性教育等基本原则。     

以实践为基础的历史辩证法——读《1844年经济学—哲学手稿》

马克思哲学的先进性不仅体现在理论内容的科学性上,而且体现在思维方式的先进性上。马克思早在《1844年经济学———哲学手稿》中就建立了以实践为基础的历史辩证法,这也为马克思主义哲学后来的创立和发展提供了一个方法论依托。本文仅以《1844年经济学———哲学手稿》为研究对象,从马克思的自然观念、人的概念以及人与自然的关系理论中分析马克思的实践的历史辩证法。
