Edutainment



Video Games as a Lesson Vehicle
            When it comes to video games, it's fairly easy to find one with a physics engine or foundation.  Whether it's playing something like Civiballs or Crush the Castle (That's right, Angry Birds), Many use a basic projectile motion as the means of completion.  Mix in a little momentum for pushing objects over and you have a solid fun time.  While everyone has had exposure to throwing rocks, understand how distance applies to certain forces is not quite so much.  That's why I think that some games can help to give students an awareness and intuitive sense about that with which they may not have any first hand experience.
            My preferred example is the game Magnetized by RockyBrickGames.  The goal of the game is to guide a steadily moving block through gradually more complex mazes by activating magnets to pull the block closer or redirect the path.  The truth of the matter is that this may give students the impression that monopoles exist, but that can be addressed as a mind-bending follow-up.  For now though, we can use this as a demonstration for monopoled forces like gravity or Electricity.
            The inverse squared law is the non-intuitive feature that students need to grasp.  To succeed, students have to grasp that the closer the block is to the "magnetized" point, the more force is exerted on it which results in a quicker turn time.  Additionally, if you are trying to course correct after release, you come to recognize how much the force drops off at a great distance, so great changes can't be made quickly at a distance.

How useful could it be?
            While there are other great games for teaching a similar method using gravity, I have not run across many for magnetism or electric charge.  I do not think that something like this could replace a lesson on the inverse square laws but could give students something more "concrete" to base their mental models on.  By giving this kind of "force sense" with these non-intuitive concepts, students should be better enabled to visualize and to check answers for intuitive senses of correctness. 

Outcasts and Xylem



How do we fit in?
            How we currently approach the ideas of school acceptance seem to have changed over the years.  Via a video in class, in the fifties people felt no shame telling students who felt different or estranged to go study what other children are doing or wearing and copy them.  This appears to be a basic sense of social awareness, but in our push for diversity it gives the appearance of denying personal identity.  I would argue that we have to sacrifice part of our identity (our language, our humor, our political leanings) to speak effectively with other people, but part of our decision is decided what is necessary to still communicate.  I am don't see the problems for communication as being that different from "fitting in."  Additionally, part of developing into socialites is a growing awareness that even though you currently "fit in," you should still be flexible to allow others in.

Where are emotions in learning?
            A quote that we discussed was when Dewey wrote:
                        I believe that to endeavor to stimulate or arouse the emotions apart from their corresponding activities, is to introduce an unhealthy and morbid state of mind.
How I understand this quote is best related by a story.  The daughter of a former teacher of mine came back from school one day singing a song.  "Xylem up, blow 'em down."  She had the song stuck in her head and seemed to be enjoying herself.  When her mother asked what it meant, she couldn't do much more than cock her head to the side.  Her daughter had become attached to a song of a concept without understand the concept itself, with not much more of an idea than that it had to do with trees.
            Whether it is teaching about xylem or energy, it is of prime importance that students understand the concept.  It is great to find a way to make them interested in a subject area to get them to learn more readily, but we can't stop there.  I believe what Dewey's problem was was this misguided idea that if children enjoy a song about a concept, they will enjoy that concept.  The lasting emotion is not in something that goes away when you learn that it was established by a song but in a concept that is understood concretely and is well established in the mind.  When students understand the use of an idea and can apply it themselves, that brings a power and an appreciation for where that power comes from.

John Dewey Literature Thoughts



The writing in this post is based on the readings of John Dewey’s My Pedagogic Creed as well as John Dewey: A Significant Contributor to the Field of Educational Technology by Peter Rich and Thomas C. Reeves.
The Need for a Guide
John Dewey put a great focus on “learning by doing.”  Sometimes though, people forget or ignore that an expert or instructor should be alongside to guide.  If the instructor is gone, the students fumble about trying to reinvent everything for the first time again.  The instructor is there to guide the students in discovery and show how the wheel became invented without the years that it took to perfect it.  It seems like we can focus on technology that allows students to do everything on their own.  Even though technology can be very useful in bringing the experience to the student, we must not forget that there will need to be a guiding hand for productive learning to be accomplished while motivation still exists for most, at least until students are proficient enough to learn on their own.
            School is the community where we put students to develop their sense of wonder and goals.  Like a guide, the teacher knows a goal and a means for the lesson.  A child left with all of the technology of an expert is of no use unless they have some sort of goal in mind.  When students are older, we give them wire, batteries, and lightbulbs and ask them to figure it out.  Because they have a framework for setting their own goals (e.g. lighting the bulb), the students can puzzle out their own means through prior knowledge (e.g. electricity flows through wires, bulbs need electricity to light).  Even still, we have teachers there to provide guidance for those who have not discovered their own means yet and to facilitate the thought.that brings the discovery about.  For even younger students, doing the same task would likely result in broken glass.  As learners, we will flounder until we have a purpose for our technology, and a teacher is there to help the learners learn about purpose, starting by giving it to them, then weaning them off of their need for aid.
Concrete Foundations for Learning
            Dewey seems to express that we should not teach something to a student unless they have some exposure to it.  We should found every teaching on concrete experience.  Students who learn to read should experience the need of reading.  Students who study science should experience the oddities of this world and see what we are working with.  Students should be taught the use of knowledge before they are taught it.  As with current pedagogy, students must begin with concrete thinking before abstract thinking can be developed.  As technology is concerned, students should experience the importance of a subject and thus technology before we can teach them how to use the technology properly.  The student must experience, do, and learn in the process.
The importance of Context
            We have to introduce a concept so that students have an understanding of it before we define it with a “symbol.”  An example of this shoddy work is the word “energy.”  Many people use it, but few could define it in a way divorced from the ethereal nonsense it has become.  Students can learn a word and throw it around like an adult, but to use it effectively, the student must understand the meaning of the word.  We must be sure we are ready to explain the purpose of the concept and what it entails before we consider teaching students a new word.  If we don’t, all thunder and no lightning is what we can expect.
The Powers of Knowledge and Emotion
            Teachers should keep an eye open for interest because that is when students recognize their own powers.  When you can understand your world, manipulate it, and predict what it will do, you recognize the power of that knowledge and skill.  If we can help students find and keep that sense of power, we have a citizenry that is motivated to improve and learn.  A citizenry that is truly free.
            Even though he was not aware of psychological research into generating beliefs, Dewey believed that beliefs and feelings can be developed by actions first.  As teachers, we should facilitate students to do correctly and goodly, and students will value the actions as part of their identities.  From the identity, feeling and emotion come, and from them a passion for the right and good stays.
Difficulties and Confusion
            One of my greatest confusions is what Dewey means by “social life” and “science.”  Social life has become a phrase that encapsulates your relationships divorced from work and civic responsibility.  His idea seems to be an all encompassing concept that covers every way that our life is social.  This seems to be the same situation that I am in with his idea of science.  It seems to be more than the discipline and body of knowledge, but the very method of science itself.  Because of this different meaning, understanding Dewey can be difficult though rewarding task.

Pros and Cons of Technology



Good or bad?
We’ve discussed the importance of technology as a way to enhance the learning experience, but we focused on how technology can be problematic.  The most obvious concern is technology implemented sloppily.  If it is not explicitly used for a purpose, it can become a distraction like a poorly done PowerPoint presentation and can become worse than useless.  The other concern is a bit more subtle. When technology is implemented, it can replace the need for relationships.  Consequently, relying on technology instead of people can cut us off from potential friends and contacts.  As adults, we must realize that everything has a cost, and we need to be aware of what time, relationships, and experiences we are trading for our choices.
Will robots take over?
            It is interesting to hear and read records of people in times past talking about technology.  Surely part of it is our selection bias for things that sound like us, but there seems to be an awful lot of that.  As it pertains to teachers, many were worried about new technology being introduced that could replace them.  Many people become excited about new capabilities and new ways we can improve our lives, but there is always a worry about how that will change our role in society or even just our jobs.  Will new tech take our jobs?  Will robots make me obsolete?
            Back decades ago, people worried about how videos would replace the need for teachers in school.  The worry is indeed valid, but in retrospect, we recognize the importance of the immediate feedback that comes from someone capable of understanding where thinking is going wrong or even slightly wrong.  Unless the video series is explicit and long enough to cover all misconceptions that can arise, actual human contact will be necessary for maximum results.
            These fears will probably arise forever, but, as educators, part of our job will be to see new tech as potential tools – ways to bring great speakers to class to start discussions, ways for students to engage online with foreign students, and ways to make old, time-consuming activities streamlined (ala clickers).  These will make life easier and remove the need for certain skills, activities, and relationships, and as we can save time we can teach more than ever before.  How we implement will depend on our stated goals.  The more clearly we understand what our goals are, the more explicit our objectives can be, and our objectives will guide our choice of the most effective tools at our disposal.

Blog Purpose



            The initial purpose of this blog will be to document thoughts and notes about my Teaching with Technology course.  I will discuss class topics and readings of interest and try to expand on how I might implement tech in my future classrooms.  Where it goes beyond this year, if it does, is beyond me right now.
