Our students are offered multiple opportunities for success in academics, the arts, extra-curricular activities and athletics. Our students, community and staff are proud of our district and understand what it means to be a "Glasgow Scottie" and we welcome you to join us. Please do not hesitate to contact myself or any of our building administrators to learn more about our schools and district.

Yours in Education, Keith Hale. Board of Education Members. Amelia Kiser - Chair Dr. Barret Lessenberry - Vice Chair Ms. Welcome to the SchoolBlocks self-guided tour!

I agree with you and believe that Sal Khan is presenting an innovative, progressive way for teachers to better work and serve in their classrooms. Being five years removed from high school, I still remember sitting in class, wondering if the teacher had any idea how well anyone grasped the key concepts of the course.

However, when a classmate struggles, and the teacher is unable to identify what areas of the course that student has had difficulties with, then the problem will compound until it reaches a boiling point requiring serious intervention. It is true that information overload can occur — but to completely ignore all information developments is an even more fatal move. Using this technology in moderation will benefit the total learning experience for each student.

Having seen the Khan material used in a class recently to highlight a concept, I was actually quite taken aback at how rudimentary the lesson was in terms of pedagogy.

Really and truly, I found myself bored really quickly, and looked around the room and saw that the students were too. I know that you are not suggesting that this is a replacement for good teaching, but rather something to augment the understanding of certain specific ideas.

I actually discussed the use of Khan in the class with a teacher at school a while ago: In my estimation, it was just watching a virtual, didactic instructor writing on a modern form of a chalkboard.

I was there with you. It had the same Rock Star feeling. What it can provide is the opportunity for kids who need or want a more traditional lecture to get that.

Last week I had my class unlearn the short-cut for dividing fractions multiplying by the inverse. I think KA will be an amazing resource, it is free, and very valuable. Would I use it to teach my curriculum? Will it help me support my students in the future? Will I use it during class time? Will it help me see where kids might have wholes in their comprehension that I am not catching?

I wrote a post of my own in response to this. If this is what is done it is certainly far from transformative for education. Then that child utilized that knowledge to teach some of his peers or even used it to create something derivative that taught how to do something he was passionate about. Good teaching requires us to provide for various learning styles and preferences in our delivery. A study has just been released in New South Wales Australia showing that 2 of the top 12 schools were adamantly against the use of technology.

Now I love technology and am right into using it in the classroom but I am not fixated on it and actually love seeing others schools excel using a philosophy of teaching which on the surface is at the other extreme for mine. For a summary of the article that shows these results check out http: Thank you so much for your post about Khan. While I do agree with others that mathematics education is in need of a transformation, I would argue that Khan Academy, has allowed me to easily transform my own classroom without having to wait for the revolution that everyone is talking about and has been talking about for a while.

I teach at a traditional independent school and AP Calculus is still the golden egg. Whether I agree with it or not, I still have to cover 12 chapters of my Algebra 1 textbook. Inspired by your post on Connected Principals a while ago, I flipped my classroom using the content from Khan Academy. Unlike Cale who commented previously , my students really enjoy his explanations, tone and clarity and found that watching the videos and having the ability to re-watch them before a test or quiz has really helped them.

They take their own notes at home and then we share and pull the concept together when we get to class. With the formal instruction taken out of my classroom, I am now able to use valuable class time to work through the problem set formally homework and include more challenging, non routine problems I would have never sent my students home to do. My classroom looks different now. I have a clearer sense of who is really doing their work, who understands the material and who can be challenged even further.

I have found that, with this new structure, I have additional time to do student projects. We are in the midst of creating Fake Facebook Walls for famous mathematicians. So I agree with you- Sal Khan, Transformer. After March break, I will begin exploring the assessment component of Khan with my students. Like many others I can concede that The Khan Academy certainly has a place in education.

Also, as many others have suggested, I feel that its main role will be to provide support for students who need to revise a certain concept for whatever reason. It has also been noted that videos on the site are not the slickest already going around and will almost certainly face competition from large producers as the mode of study becomes entrenched. But that is a major topic outside the scope of this post.

Again, it lies outside the realms of this response. Both discussions deserve to be explored and Salman Khan deserves some credit for putting these on the educational agenda. Even as it currently stands, the Kahn Academy already has a place in schooling.

However, it lacks some essential elements for me to see it as anything other than another teaching tool — albeit a potentially powerful one. Where is the motivation of the student taken into account? If the Kahn Academy is used to provide last minute cramming before a test how is it really any different to a text book — albeit one that uses a different modality?

If the purpose of the student for learning is simply to pass a test then using the Khan Academy will simply be an electronic textbook. The approach taken by the Kahn Academy is useful as tutorials for specific skills. This is what it is designed to do and so it may seem odd to criticise it for this feature. Why do dolphins leap from the water? How many hours teenagers volunteer per week? What is the average cost of a textbook? What is the average weight of the human eyeball? How many active volcanoes are there in the world?

Why do we have different seasons? What is the most common weekly allowance? What is the average lifespan of a human taste bud? What country consumes the most chocolate per person?
