Bertrand Russell (1926) stated that when we have asked ourselves seriously whether we really know anything at all, we are naturally led into an examination of knowing, in the hope of being able to distinguish trustworthy beliefs from such as are untrustworthy. Thus Kant, the founder of modern theory of knowledge, represents a natural reaction against Hume's scepticism. Few philosophers nowadays would assign to this subject quite such a fundamental importance as it had in Kant's "critical" system; nevertheless it remains an essential part of philosophy. It is perhaps unwise to begin with a definition of the subject, since, as elsewhere in philosophical discussions, definitions are controversial, and will necessarily differ for different schools; …show more content…
In other words, most researches firmly believe that knowledge is constructed, but some (e.g. main stream instructional designers) do not adopt an instructional design that is labelled "constructivist".
Typically, a constructivist teaching strategy is based on the belief that students learn best when they gain knowledge through exploration and active learning. Hands-on materials are used instead of textbooks, and students are encouraged to think and explain their reasoning instead of memorizing and reciting facts. Education is centered on themes and concepts and the connections between them, rather than isolated information. Constructivism is first of all a theory of learning based on the idea that knowledge is constructed by the knower based on mental activity. Learners are considered to be active organisms seeking meaning. Constructivism is founded on the premise that, by reflecting on our experiences, we construct our own understanding of the world consciously we live in. Each of us generates our own "rules" and "mental models," which we use to make sense of our experiences. Learning, therefore, is simply the process of adjusting our mental models to accommodate new experiences. Constructions of meaning may initially bear little relationship to reality (as in the naive theories of children), but will become increasing

In the most general sense, it usually means encouraging students to use active techniques (experiments, real-world problem solving) to create more knowledge and then to reflect on and talk about what they are doing and how their understanding is changing. The teacher makes sure she understands the students' preexisting conceptions, and guides the activity to address them and then build on them.
Dialogic teaching Dialogic teaching harnesses the power of talk to stimulate and extend students’ thinking, and advance their learning and understanding (Alexander 2010). The term ‘dialogic teaching’ is now in regular use but like all such terms means different things to different people. As developed by Robin Alexander since the early 2000s, dialogic teaching harnesses the power of talk to stimulate and extend students’ thinking and advance their learning and understanding. It helps the teacher more precisely to diagnose students’ needs, frame their learning tasks and assess their progress. It empowers the student for lifelong learning and active citizenship. Dialogic teaching is not just any talk. It is as distinct from the question-answer and listen-tell routines of traditional teaching as it is from the casual conversation of informal
