The article underlines the emerging of design-based research by making connections with learning sciences. Differences between experimentation and design-based research are offered and terminologies that are similar to design-based research are dicussed with similarities and differences.

I especially liked the table, comparion experimentation and design based research. It made me clear about some issues, thanks :)

Dr. Susan McKenney discusses the balancing act that design-based researchers have as they take on multiple roles as researchers, designers, and practitioners. She also discusses the collaborative environment created by conducting research with multiple people on the research team.

Research on how deliberate practice combined with innate abilities lead to expertise.

Elanur, Actually, I was trying to find the movie that you mentioned about high-wire actor (Petit). Then I realized that you have already written here. What made me so impressed about him that he worked on that about 6 years. I have read somewhere "experts view mistakes as opportunities to learn", however, this man had no chance to do mistake. the story of the guy in this link http://ny.curbed.com/archives/2015/09/30/the_real_story_behind_philippe_petits_highwire_act_in_the_walk.php

Yes Yasin I totally agree with you about the mistake part but this man dedicated his life to perform on the wire between Twin Towers so I thought that someone who dedicates oneself to perform in a particular area develops expertise in that area eventually and we can call him an expert in being a juggler even he put his life in danger. By the way this is an extreme example of being an expert. I just try to make connections between dedication and developing an expertise through this example.

The first problem is defined by Dan Lortie in The Apprenticeship of Observations (1975) as being acquainted with the task of teaching.The professor on the video emphasizes that in the countries where immagrants are most successful, teachers spend 50% of their work planning lessons, observing other classes and negotiating about the lessons. She also touches the problem of 'Toxic Environment' of schools for teachers where they gossip about their students and colleagues. She gives a successful school example in which professional development is a part of school culture. Can you list additional problems for teacher expertise faced in schools?

Although sharing ideas and instances about the classroom hours and students can be accepted as components of adult learning for teachers, gossiping about them can be a real barrier to develop on those areas. In my teaching experience, we prohibited the conversations about the negative issues happened in the school.

When decisions with important consequences involved, people ask for expert opinion let it be a hotel booking (trip advisor, booking...) or purchasing a book (amazon recommends, kitapyurdu...). If the stakes are high, then it becomes obligatory to go and ask for expert opinion. However this becomes a problem if people rely on experts as if they are getting parental advice. People become addicted to experts because of its certainity, assuredness and definitiveness. In a study, a group of adults' brains' MRI scans when they are listening to experts showed that the independent part of their decision making part of their brains switches off while they are listening. This listening becomes unquestionnable and they use these opinions without distinguishing as right or wrong. Considering the doctors who misdiagnose 4 out of 10, not questionning is an important issue. As a result the role of the expert should change because they are affected by social norms, cultural norms and everything. So their judgements may differ. Think about companies who try to sell their products and include experts in the process. Toothpaste, washing detergents etc. are exagerated. Although they are experts, they have assumptions which may have flaws. People should question and become skeptical about experts. People should not blindly accept or listen, rather they should open their eyes wide open, face the world, use experts for certain things but be aware of their limitations and also their own.

This video make some advices for teachers about how to implement Learning by design in their school.

This video is an episode from the bakyard science program on yumurcak TV. In this program, children design tools based on their problems by this way, they try to understand some science subjects.

This is a collaborative mindmap originally started during the LearnTrends live online event on November 16th 2008. In that web event, over 100 people led by Robin Good collaboratively created this large map identifying as many as possible of all the available online collaboration tools, giving initial preference to those providing a free access plan versus the high-price corporate solutions.

This talk was given at a local TEDx event, produced independently of the TED Conferences. In her TEDxJacksonville talk, she vividly depicts the incalculable value of memory and movement, and the devastating biological effects of these diseases on the brain. She also details recent advances in computing technology that may help elucidate treatment targets for Alzheimer's and Parkinson's diseases. "We are now building revolutionary computer simulations of neurons," she explains, "so we can have better insight into the molecular behaviors of neural cells so we can see a play-by-play of the interworking of neurons rather than static pictures frozen in time."
