Explicit instruction limits learning . . .

I often teach technology to students quickly. I often start with the comment, "I know many of you already know how to do this but if you'll give me a few minutes I might remind you of something you've forgotten." Once started, I try to keep things interesting and fast paced and will say as I skim rapidly over very important tips or techniques, "If you need help figuring out how to [get here / do this / take the next step] let me know and I will be glad to help you."

I have found that this method causes students to try harder to figure out how to do things they may have struggled with if I taught in greater detail. I think we (all) tend to rely on as much assistance or guidance as we can get and only when pushed to extend ourselves does our creativity and motivation to learn by doing engage. This seems to me like the basis of constructivist learning and the model we should all pursue as educators.

I watch teachers repeat basic instructions again and again until, "everyone in the class gets it," but notice that it sometimes takes forever and in following lessons students need the explanations again and again. With my method, after the first time, when I tell the students, "This is easy and I know nobody will have a problem with it," if I have to revisit later it is done individually or very quickly to the group with a preface like the one above.

A recent MIT study seems to confirm my rationale and support my opinion that sometimes to promote learning, when it comes to teaching, explicit instruction, less is more.

Suppose someone showed you a novel gadget and told you, “Here’s how it works,” while demonstrating a single function, such as pushing a button. What would you do when they handed it to you?

You’d probably push the button. But what if the gadget had other functions? Would it occur to you to search for them, if your teacher hadn’t alluded to their existence?

Maybe, maybe not. It turns out that there is a “double-edged sword” to pedagogy: Explicit instruction makes children less likely to engage in spontaneous exploration and discovery. A study by MIT researchers and colleagues compared the behavior of children given a novel toy under four different conditions, finding that children expressly taught one of its functions played with the toy for less time and discovered fewer things to do with it than children in the other three scenarios.

According to Laura Schulz, . . . Associate Professor of Cognitive Science at MIT, this is rational behavior, as teaching is meant to impart skills quickly and efficiently. The danger is leading children to believe that they’ve learned all there is to know, thereby discouraging independent discovery.

Learning you can see!

Check out this great new tool! Create a video trip across a map complete with music and captions in minutes on TripLine.

In conjunction with our focus on Black History Month, check out this demo of King's march from Selma to Montgomery. Click "Full Screen" for best effect and press the play icon to start video. Click on the caption summary boxes to pause video and read an elongated caption.

It literally only takes minutes to create a project like this! Available tools allow you to select points through search or by dropping directly on map. Text and pictures are easily added as captions. Uploaded pics can create trip automatically using time stamp and geotags! A diverse selection of music is available on the site and adding is as simple as a click!

Great tool with potential uses in any subject from mapping civilizations to wars to political campaign trips. Highlight a biography, an event, a mission or even a period in history; Where were the hotbeds and turning points of the Industrial Revolution? Maps can be made with connecting lines or without for projects like this.

Would love to see a map of Homer's travels, the Iditarod sled race, and my next vacation (or my last). Maps can be made public or private with a simple click.

Registering to create your own maps on TripLine is is simple and easy but many maps are available for viewing without registering or logging in. I give this site an A++ rating!!

YouTube - the new copyright cop!

The copyright ©law cometh! The blogosphere is abuzz with news about the new YouTube policy of "muting" videos that contain copyrighted music. Very few videos have been affected by this policy so far but the potential is mindboggling!! Our students and other teachers may begin to see us as the copyright information specialists we are and no longer as the "copyright cops" they have perceived us to be. "There's a new Sheriff in town."

According to a Rolling Stone article, "YouTube Hits the Mute Button as Royalty Fight with Warner Bros. Continues" the policy currently only affects Warner Music Group releases. Videos being muted are tagged with the comment, “This video contains an audio track that has not been authorized by all copyright holders. The audio has been disabled.” They further report, "YouTube said in a statement issued after the muting began, 'Now we’ve added an additional choice. Instead of automatically removing the video from YouTube, we give users the option to modify the video by removing the music subject to the copyright claim and post the new version, and many of them are taking that option.'"

Both those who post to and who watch and listen to YouTube will feel the pain. As a consumer of music and video, I empathize with these users and will miss the popular, high-quality audio, but as an educator I am in full support of this policy and hope that it extends to all protect all studio releases. I have agreed before that our copyright law is in need of massive revision but I have also advocated strongly that creators should be allowed to earn a profit from their creations! Adding popular music, purchased or "borrowed," to videos and publishing them for mass consumption without compensation to the creator of that music is, by any reasonable revision of the law, infringement.

As teachers and librarians teaching in "project based" environments, we allow some level of legal (within the confines of the classroom) copyright infringement. Our students do not understand, though, that using an audio clip on their class video project is legal but posting the same clip to YouTube is not. It has been our responsibility to try to explain this concept, but lacking any form of evidence of the illegality by peers or providers on the Web, the explanations have fallen on deaf ears. We have been the nagging, copyright cops. A solid and sincere effort by You Tube, and other video hosting sites, to mute illegal posting of copyrighted music will not only protect creators, but will lend credence to librarians, and others who have assumed a responsibility for informing the public about the laws and attempting to protect creators.

Will this be the end of YouTube and publicly shared videos as we know them? I think not. It will be an obstacle to be hurdled. Many current users will, initially look for other hosting sites or ways to get around the filters. Beware the abusive and pornographic comments being added to every unmoderated blog and discussion group covering this story! Eventually though, this, like many obstacles we face, could make the system stronger and better. I will not attempt to predict specifics of the future, but feel confident that amateur created streaming video will mature and grow as a medium of entertainment and education for years to come.

Better Pedagogy

Did I mention that I am taking three classes this semester? Met my family a few days ago and needed introductions. Talked to my Dad on the phone and commented on the amount of content output we had to create in this program as compared to the graduate programs he used to take. Not sure if it is the fact that our focus is information literacy or if this is how graduate school is taught today.

Focus this week in another class was how to teach an information literacy lesson that connects with the students, fostering “creative, reflective, and critical habits.” After reading Heidi Jacobs article, “Information and Reflective Pedagogical Praxis” (2008), it is apparent that many of us revert to a forced or “banking model” of education instead of striving for a more constructionist or conversational method.

To interest students in information literacy, we must first forget the theoretical. Many students tend to be disinterested outside of preferred topics (e.g. sports) or ones they see as threats against their personal interests or liberties (e.g. dress code). To implement an effective lesson, we must first engage students. Perhaps a conversation about past searches for information would work as an icebreaker for a lesson on search strategies. This conversation would also act as an assessment tool regarding current levels of expertise and a starting point for the lesson.

Instead of preaching the benefits of database research, perhaps the lesson should begin with discussion about acceptable and unacceptable sources for various types of information from an assortment of print sources displayed in the class – various magazines, journals, newspapers, phone books, encyclopedias, non-fiction and fiction books, student term papers, yearbooks, etc. As the group analyzes these sources in the real world, they may develop a greater understanding of sources in the virtual world.

The lesson could continue with group development of search strategies to find information students had struggled with in the past. By involving the group, discovery of alternate keywords might grow almost like a game instead of an individual drudgery. Discussing and having students demonstrate databases that they use regularly may eliminate some of the confusion and frustration regarding leased databases. Students seem to be well aware of TVGuide, imdb, Amazon, imeem, NFL.com, ESPN.com, WhitePages, and others.

So many librarians focus on the mechanics – how to use a database. The majority of students will figure the mechanics out very quickly if we can convince them that the answers to the question can be found more easily here than on the web. This lesson needs to be the focus of our “instruction”.

Concluding with a game of stump-the-librarian may be helpful in reinforcing successful strategies. Rules could allow group or individual work by students, students and librarian choosing topics alternately, and winners based upon group evaluation of source quality.
