Learning to Teach

I just finished reading Dana Goldstein’s “The teacher wars“. I found the book to offer an even-handed and deep evaluation of educator performance and public opinion of teachers and the teaching profession. Much of the book takes an historical perspective which may bore some readers. The author takes this approach to explain how the public understanding of education, expectations of teachers, and the politicization of attitudes directed toward education in contrast to other areas of public service has come to be. I know that groups of educators sometimes engage in “book studies” and am aware of many of the books that are selected. I recommend such groups consider this book – it is complex and may not paint a “feel good” picture, but I think it is realistic and takes on specific issues that will continue to shape education. My concern about practicing educators is that they avoid issues that really end up having significant impact on their lives and the lives of students. Perhaps they feel these issues cannot be changed. Perhaps they feel that these issues are too political. I would encourage both deeper understanding and greater advocacy.

My intent here is to identify one of several topics from the book I thought might resonate with practitioners. The author describes teaching as having a “steep learning curve” that beginners encounter with limited practical preparation. There are multiple sub-topics. One target was teacher preparation. It seems college programs do not offer future teachers enough experience in developing what I call “tactical” skills. There seems too much emphasis on abstraction and not enough on practice. I used to teach one of the “abstraction” courses (educational psychology) and I have mixed reactions to such concerns. Recipes for practice have their own limitations and knowing why things work as they do can inform the constant decision making that is required in an applied setting. I suppose the point is when in a career is deeper understanding helpful and what can be done when there is limited access at different points in a career path. Knowing that future teachers had micro teaching, methods and field experiences of various types, I could conveniently assume that teaching tactics were up to someone else. I would suggest that the quality of supervised practice varies greatly from situation to situation and is a great preparatory challenge. Teacher education programs must pretty much take what they can get when placing students and I think realize that many opportunities offer little in the way of mentoring or quality models. So often it seems a money game. Programs operate on tuition dollars. More students mean more tuition. Running an elite program focused on fewer students generates insufficient funds. Educators believe student skills can be improved (students in this case are college students) and the public (e.g., parents) assume this as well. It is complicated when you are in the middle of such situations.

Whether because new teachers are missing important skills or because there is much to learn, it is clear that the learning curve is steep. A very high proportion of new teachers quit after a year or two. In undesirable settings this churn is the greatest and this lack of stability adds to other problems specific to such schools. One thing I know from my study of technology usage in K-12 settings is that new teachers tend not to generate what we have hoped to see. It may appear that this implies poor preparation. However, if one waits just a few years, newer teachers are more creative in their use of technology. This is a classic case of a learning curve and priorities. It is not necessarily that the new teacher has a poor background, it is that thess skills and knowledge do not materialize until the teacher develops a sense of the environment and likely finds classroom management skills that are effective.

Goldstein points to the value of what I would describe as “on the job training” as particularly important in the development of new teachers. Are administrators and other teachers willing and capable of offering specific suggestions. Do new teachers have opportunities to observe effective peers? Are new teachers offered additional time for planning? Are a greater number of “problem children” dumped on the new guy?

Goldstein suggests that experienced and new teachers likely have things to teach each other. Practicing teachers have concrete suggestions related to classroom situations. New teachers likely have new ideas – things they know but may not apply until the basics are under control. I wonder about the potential of technology to bring these two knowledge sources together. Are present means of interacting specific enough to be beneficial?


Net neutrality issue going mainstream

I have fallen into writing about some topics that seem beneath the radar for most ed tech bloggers. I assume many writing about ed tech have a local focus and avoid topics that have a political tinge because they would prefer to remain apolitical or because they assume they cannot make a difference.

I became interested in what is called “net neutrality” in 2005/2006. Because the phrase seems to mean different things to different people, I define neutrality as an ISP being agnostic as to the type or source of content delivered to a user. Some used to describe this as “bits is bits” – meaning the user pays for access at a certain rate and the provider should not be able to manipulate the content the user desires to consume.

I understood the original concern to be that providers could use their control to prioritize other services they might provide. For example, a cable company selling premium movie channels might advantage such channels by making it difficult to download content purchased from a service such as NetFlix. A DSL provider might reduce the quality of Skype or some other VOIP service to advantage the phone services it sells.

More recent concerns focus on content providers allowing some to “fast track” their content by making deals with service providers.This multiplies the advantages of existing successful companies making it difficult for new companies or hobbyists to contribute content.

Just for the record, I do not accept the argument that a net neutrality position prevents businesses from generating a reasonable return on their investments. Much was invested before the large companies became involved. The Internet was not created by business ventures or ramped up by commercial content providers. The Internet came from the research community and was pretty much developed by hobbyists. Business entities came into the game once profit potential was established. The supposed great risks they take are not exactly the risks of R&D. Also, those companies in a position to offer these services were few in number and already well established. By building on top of the cable or phone companies, the services were provided in sectors of the economy that were already close to monopolistic. Many of us live in areas of the country with one option and a low quality and expensive option at that.

The President has now taken a solid position on net neutrality. A position taken by the President has generated the typical response from the republicans.  This could easily be framed as a small business vs big business issue. Those who read tech blogs probably know about this issue, but the dem vs republican angle may now bring the topic to the attention of the average citizen. I think positioning this as a red/blue confrontation is unfortunate, but this may be what it takes to generate some attention. I am concerned we are losing sight of the original promise of the Internet and will become limited by the financial goals of a few large companies.

30 Hands – Preparing Suet Demo

There are several iPad presentation apps based on a “voice over slide approach”. Explain Everything is the app from this category that seems to have received the most attention. I think this type of app offers an efficient way for students to create videos. The advantage is that these apps allow the audio to be generated on a slide by slide basis. This approach makes it easy to redo the segment of audio associated with a slide when an attempt to generate the segment comes up short of expectations.

30 Hands takes a similar approach and has similar capabilities. Again, the author generates “slides” in various ways and then records the audio to accompany each visual. Slides can be generated in multiple ways (see below).


The following is a quick demonstration I created with 30 Hands.

Teacher Preparation and the New Political Environment

The recent election has brought a shift in political power to Washington. Assuming a simplistic vote along party lines both houses are not controlled by republicans and the President is a democrat. One wonders whether the contentious politics of the past two years will continue. Democrats in the Senate could now play the Republican game of the past two years and prevent passage of pretty much anything. Will the “party of NO” wear a different color jersey?

Leaders, Mitch McConnell and President Obama, have been remarkably pleasant and promise greater efforts to work together on areas of agreement. While it may have seemed that no such areas exist, to avoid the “party of no” strategy, Republicans are now likely to identify some such areas (in addition to pushing through legislation that the President will obviously veto).

One such area may concern teacher preparation and teacher evaluation. Republicans and Obama’s Department of Education have been supporters of the “value added” mentality. I single out Republicans only because it seems this concept is somewhat more accepted by Republicans. This is a simplification.

The idea of value added proposes that the contribution of teachers can be estimated statistically by using student gain scores after attempting to control for some confounds. It follows that if the value added of a teacher can be determined than the average value added of the institution preparing these teachers can also be estimated. It kind of makes sense on the surface, but the practical significance of value added in contrast to variables other than the teacher and issues of what the dependent variable used in statistical should be make this very controversial. By dependent variable (a stats/research kind term), I mean what will be used to evaluate “gain”. This probably translates as some type of standardized achievement test. Even standardizing on a standardized test will be a struggle that will probably not be resolved. You will then have a mess with different standards in different states and teachers trained in one state teaching in other states making the use of gain scores to evaluate teacher training an apple and oranges mess.

So, without weighing in on whether this will be a good thing for learners and educators, I am just predicting that politicians will see this as an area to address. Teachers are an easy target and politicians will want to point to something, anything, they have accomplished.

365 vs Google Apps

I see today that ND EduTech has Office365 for K-12 working. Higher Ed in ND offers the same system. The release was described as offering students 21st Century Learning tools.

Just for the record, I regard Microsoft as lagging behind Google in developing cloud services (and Apple in developing hardware). Both Apple and  Microsoft have been pushed toward cloud applications by the success of Google.  Having used all of these systems, I would rank them Google, Microsoft, and then Apple.

It is interesting that Microsoft seems have to changed the company approach to pay attention to K-12. Apple used to have this focus with the logic that this emphasis might create future adult users. Apple seemed to back away from this focus as its hardware products became the industry leader is many categories. Microsoft may now be taking a similar approach. Note that the free/low cost to students is a way to get individuals invested in the platform. The “adult” version requires a purchase. Of course, Google apps are ad supported for adults. Will most adults purchase Microsoft products for themselves?

I find Google docs easier to use for peer collaborative writing and peer editing. Any system, Apple, Google,  Microsoft has a way to collaborate, but I find the Google approach easier to use. I also see the total “suite” offered by Google better suited to education. To my knowledge, there are no Microsoft or Apple equivalents to Sites, YouTube, Hangouts, Forms or Blogger. I see these products important to developing the multimedia authoring and collaboration skills of students. Contrary to the notion of 21st Century skills, learning, etc., the Microsoft offerings are both dated and limited in scope. I give Microsoft an advantage for OneNote.

Hosting social bookmarks

While I recognize the quality of the free or inexpensive social services I can access, I prefer when possible to host services from a server that I control. If you want to develop insights into how technology and specific services work, doing it yourself really gives you a closer look.

Some time ago, I operated a social bookmarking service using open source software called Scuttle. I modified the php code of Scuttle to provide some additional services – allowing users to promote sites they found useful, listing sites by total value to users. Hacking open code is certainly part of the way I learn.

I began to have difficulties with Scuttle and I never figured out if it was because of the code I added or limitations in the original code. There is a problem with MySQL called sql injection. Code included with invited input can cause problems that coder does not intend. This seems to be what happened and while I investigated how to clean up the problem I failed to prevent it completely. It seemed my site was on a list of vulnerable sites somewhere and problems became more frequent. I eventually removed Scuttle from the server.

I am trying it again. This time I am using open source bookmarking software named Shaarli (share links). The software does not use a database backend so this will eliminate the problem I encountered with Scuttle.


My intent is to develop an online source of educational resources. I “seeded” the site using the links I have stored in my Diigo account and plan to add mostly content-specific links as I find them. Take a look at Grabe Bookmarks.

How I Work

I see these blog posts in which recognizable individuals show their office or explain their work strategy. I make no claim to being recognizable nor will I provide images of my office (it is presently pretty cool – a three season porch looking out on birch, pines and a lake with a fire burning in the stove), but I thought I might explain how I write for online consumption (not the same as writing textbooks). The tools I use may be of interest to some.

My daily process involves the use of input tools that I use to surface content that I read. I would divide these tools into three categories – social tools (Twitter, Google+) for following specific individuals, an RSS feed I use to follow specific bloggers, and discovery tools that follow topics, but not individuals. As I go through this content, I annotate and move interesting content into Evernote. I mostly write in Evernote. I write when I have time and when something I have found seems interesting. I generate blog posts from individual or multiple inputs and draft these posts in Evernote before generating the final versions in WordPress (my three blogs). Of course, I also search for additional information related to topics I am writing about and sometimes write based my original ideas rather than in response to what I have read. I keep content in Evernote for future reference whether or not I write something. I use Diigo as a social bookmarking site mainly as a way to share resources related to our textbook. I pay for pro/premium Evernote and Diigo accounts to allow for expanded capacity.
