Constructivism represents one of the big ideas in education. Its implications for how teachers teach and learn to teach are enormous. If our efforts in reforming education for all students are to succeed, then we must focus on students. To date, a focus on student-centered learning may well be the most important contribution of constructivism. This article, therefore, discusses Constructivism as a paradigm for teaching and learning. Constructivism is learning theory found in Psychology which explains how people might acquire knowledge and learn. It therefore has direct application to education. The theory suggests that humans construct knowledge and meaning from their experiences. Conceptual understanding of the theory was discussed as well as basic characteristics of constructivists learning environment. Seven pedagogical goals of constructivist learning environments and six benefits of constructivism were outlined in this article. Significant difference between traditional classroom and constructivist classroom were spelt out in tabular form. Furthermore, principles of constructivism and several implications of constructivism for teaching and learning were received. The study, therefore, concluded that teacher needs to reflect on their practice in order to apply these ideas to their work and that constructivist teachers need to reflect on their practice in order to apply these ideas to their work and that constructivist teachers encourage students to constantly assess how the activity is helping them gain understanding.
