In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the student is describing how all atoms are the same. He begins by drawing his own mental model of an atom and explaining that all atoms are made up of protons, neutrons, and electrons. He says the air atom is the same as the aluminum foil atom. He goes on to describe other things that are made up of the same particles. The interviewer probes further to find out if atoms of different substances ar
Looking at Learning ...Again, Part 1: Workshop 2. Intellectual Development
Explore the power of the mind and consider the notion that every child can learn everything. Harvard Professor Eleanor Duckworth discusses the importance of teaching for a deep and lasting understanding and explains why it is important to give students time to work through their own ideas and experience confusion in order to achieve such understanding.,This segment is about the importance of experiencing ideas or concepts before terms are introduced.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment shows a strategy to identify students' ideas about how the surface of the earth has changed over time. The interviewer probes to elicit the idea that the organisms in the fossil came from water. He then challenges a student's thinking about fossils forming in water by showing a map of the location where the fossil was found. This creates dissonance as the student struggles to try and figure out how
Looking At Learning ...Again, Part 2: Workshop 4. Conceptual Change
With Dr. Peter Hewson. In this workshop, we explore the role played by prior knowledge in the learning of new science ideas. Only when a new idea is understood, accepted, and found to be useful does it begin to be exchanged for a previously held scientific belief. The workshop examines how teachersÂ’ ideas about teaching and learning may be altered as they engage students in strategies designed to promote conceptual change.,This interview discusses the conceptual change model, in particular that

On Determinism from the course History of Information
This course explores the history of information and associated technologies, uncovering why we think of ours as 'the information age.' We will select moments in the evolution of production, recording, and storage from the earliest writing systems to the world of Short Message Service (SMS) and blogs. In every instance, we'll be concerned with both what and when and how and why, and we will keep returning to the question of technological determinism: how do technological developments affect socie
Private Universe Project in Mathematics: Workshop 2. Are You Convinced?
Proof making is one of the key ideas in mathematics.
