Trail Camera

My brother Dan is an engineer, but he has a unique hobby. He develops wildlife habitats. The “riparian” is a seventeen-acre plot developed on a farm Dan and a couple of my relatives own in Iowa. Dan hunts there some, but mostly just enjoys the challenge of restoring the habitat and watching wildlife.

His new toy is a “trail camera“. This is a fairly inexpensive digital camera that is triggered by movement. You set up the simple camera in an area (a trail I suppose) where you expect wildlife to be.  After some time passes, you come back and see what images you have collected.

Dan sent me a few pictures a couple of weeks ago (a partial frame with a deer and some geese on the beaver pond you see above), but this new image is really pretty cool. There must be some educational applications here. What about the reality of not being able to take frequent field trips. What if a class could position a camera (via a teacher or a student with access) and then explore what they might find?

I have had this debate with teachers, sometimes biology teachers, from time to time about technology. I often do not immediately reveal some of my personal interests. The teachers often assume that my use of technology involves siting in front of my computer and exploring virtual worlds. I ask about their last field trip and what they and their students did afterwards. Virtual worlds are actually not my thing – I like being there. I tell them after my trips I continue to explore what I saw.

Maybe it has been made out to be worse than it is

It has been a while since I have posted here. I have been working on some other writing projects, posting on my microblog, and reading. I have decided I want to use this site for longer and more serious posts and the microblog for identifying resources I come across and for just playing around.

I wanted to finish the book I have been reading before writing something for this site. The book, Fertilizers, pills, and magnetic strips: The fate of public education in America (G. Glass), has a strange title, but a very interesting concept. There are many components to this book, but a core idea is that the reform agenda focused on supposedly underperforming public education is far less about offering quality education to all students and more about the political struggle to reduce the cost of education for most while securing opportunities for the wealthy. The title is weird (I may make the effort to explain later), but there are a couple of useful components of this book – a discussion of whether the data used to evaluate general achievement in public schools really demonstrates the fading of US schools in comparison to international competition and an explanation of how the present constellation of reform strategies (home schooling, vouchers, charter schools, high stakes testing, voucher systems, and tuition tax credits) are really mostly about discrediting public education so that public investment (taxes) can be reduced and those with greater wealth can focus their resources on themselves and their children rather than “other people’s children”.

What about the test data? I have read a book on standardized tests and the perspective that is perpetuated based on shoddy analyses of these data before (Berliner and Biddle – The manufactured crisis). Glass mentions their work and comments on how it has largely been ignored. You have to understand that Berliner, Biddle, and Glass are some of the real heavy weights in the evaluation and applied statistics field. Glass is usually credited with “meta-analysis” – the statistical procedure used to combine the outcomes from multiple research studies in a way that allows some general statement about the effect of the treatments involved. If you come from the position that one should reach conclusions based on sound methodology and data, these folks are legit.

Anyway, Glass concludes that the data from various tests (SAT, NAEP, TIMMS) used to argue that US schools are failing miserably really do not warrant such conclusions. Among some of the issues I highlighted:

The SAT is really not a test designed to evaluate K-12 achievement. It is an test designed to assess aptitude for college performance (hence the name scholastic aptitude test). It was specifically designed to predict performance in some specific areas and not appropriate to test a wide range of skills and knowledge.

The TIMMS is often used as the basis for international comparisons. This is actually challenging and is based on important assumptions – groups are equivalent, content receives equal emphasis, content knowledge and skills are understood in the same way across nations. As examples of some imortant issues, Gage points out that the science and math components rely on the metric system (still not the common measurement system employed in this country), the US was among 4 countries that did NOT allow the use of calculators, and education systems are not equivalent in terms of basic characteristics such as the age of high school students (e.g., Icelandic test takers who happened to score above the US in math averaged 21.2 years of age – roughly equivalent to a US college junior).

Gage suggests that the most appropriate use of exam scores for states or nations given some of these measurement challenges is to determine whether scores are going up or down. Contrary to what one might assume from reading the local papers, scores in the U.S. are increasing.

I do not pretend to be a measurement expert – the issues involved in exploring the complex datasets used for such analysis are not the type of thing I play with when I sit down to run some regressions or a MANOVA in SPSS. I do think it is fair to suggest that the arguments Glass makes are not the message you have probably encountered from the usual sources. If there are counter arguments, I would like to hear the debate.

And Reality Sets In

My first post from AERA involves a topic I did not anticipate. I assumed I would offer something related to an inspiring session I had attended. No luck so far. Instead, I find myself writing about conversations I have had with colleagues and with the all too frequent topic of these conversations. Higher ed folks are experiencing the same budget cuts so common in other industries. Words like furlough, layoff, adjusting course loads, and budget cuts seem to come up in most conversations. The convention itself is smaller and this was apparent reading the newspapers on the way here. This is typically a very large convention 12,000-14,000 and I suppose it makes sense that graduate students and junior faculty members would really struggle to find the means to get here. I wonder about those who have made a full-time commitment to a graduate education and now must try to find that first job. It really is a leap of faith or a commitment to a cause when you spend four years dedicating yourself to this goal. We admire risk takers and true believers, but we tend to think of business entrepreneurs as our examples. Why is that?

I have been attending sessions concerning 21st century skills and new media. I am still trying to understand if these areas are really new to me or simply represent a new vocabulary. I still like higher order thinking skills and participatory media – similar ideas I think. The one paper that intrigued me was from a U of M (that is Minnesota in my neck of the woods) group that were examining new media use among struggling readers (more on the specifics in a later post). The core idea, if I am interpreting correctly, was that by middle school a significant group of students have given up on reading or at least text-only content. New media may offer an opportunity to engage these students again. It appears that students were engaged, but may still be capable of avoiding the text components of projects by using options such as audio instead.

I like to think I keep up on emerging trends, but often I find myself interpreting using older models. I think this is how the constructivism thing is supposed to work. Many of these ideas of interdependence of production/consumption and modalities sounds a lot like the “language experience” model. Communication is a more basic process than specific skill areas such as reading and writing, speaking and listening. As I remember a core premise, these skill areas offer the potential to inform each other if the setting for learning a given skill does not decontextualize that skill from the others.

Back to the budget thing. The session I am sitting in writing this ended up with a different orientation than I expected. Several presenters did not show and the focus that remained was hip hop and the use of this genre in urban schools. Not what I came to hear. Can’t blame those who made it.  Hip- hop would not be my thing, I am more of a jazz and blues kind of guy. I also don’t teach in an urban setting. Exploring new ideas, hip hop included, takes both time and money. I wonder how the public costs out such ventures. Some may not understand hip hop in the classroom. I think your beliefs have to accept that these folks are trying to find ways to engage kids and the challenges in doing this work in these kinds of settings may not be apparent to those who view the effort from another time and a very different place.

Blogging a Conference

I am approaching what for me is conference season. I attend AERA, NECC and the North Dakota edtech conference (TNT) in the next couple of months. The rest of the year my budget and job keep me at home. I write a few posts while I attend conferences and I read the posts of others some whom attend many conferences.  So, in a way, I am a producer and consumer. I know what I like to produce and consume, but I am attempting here to offer a broader perspective which requires that I  broaden my comments by pulling in thoughtful posts from others.

Here are the question. Are blog posts and Tweets authored by those who attend a conference helpful? What should those who post keep in mind to make their contributions useful?

AERA is next week and the Twitter chatter has been picking up for weeks (use AERA as a search term in TweetDeck or Nambu). I have also noticed that AERA is a frequently misspelled option for area and as a consequence weird things show up. AERA has not been a major bloggers event. I could not find it as a destination in David Warlich’s hitchhikr. I have always thought that someone ought to pursue the topic of “Why researchers don’t blog”, but we will save that topic for another day.

A comment on Twitter: I do not encourage frequent conference tweets especially from those who think they are live blogging. This is a personal thing, but consistent with what I think I get from Twitter. I can see Twitter as a useful backchannel tool, but just how often would I be in an AERA session with others who Twitter. Perhaps at NECC this might make sense. Sorting out a string of tweets to gain some sense of context and flow is too much of a hassle. Wrong tool. Don’t be lazy – share what you learn via blog posts so there is some flow and continuity.

There are others with other opinions. I tend to focus on information exchange. Others see the social networking advantage of Twitter. As I understand their perspective, a conference represents an opportunity to network with other professionals. Twitter can facilitate connections using the conference or conference events as a point of departure. Twitter offers a second opportunity in the post conference time period to follow up on what seem to be common interests. So, I guess – find new folks to follow and possibly meet to network.

Blog posts from a conference: I have researched the topic of conference blogging previously and there are some classic analyses. Here is a group-based approach from 2006. By group-based, I mean an approach by which a group makes a collaborative effort to offer a thorough review for others. AERA is a little to large for such a commitment. I remember reading a description from 2004 that identified major categories of conference blogging and I was able to still locate it. I like nice categorization systems. My posts typically fall into the reflection category – I pick up an idea for a single presentation and offer a comment both attempting to convey the original message and offer something more. If you really want to take the conference blog on as a serious mission, you might even download a pdf that attempts to organize tips for you to follow.

After making this sound like a serious pursuit that requires preparation, commitment and follow through I am starting to wonder if I have not set myself up to disappoint. I hope not. On the plane for San Diego in the morning. Might as well take advantage of the holiday to take a little time away from the snow and cold in North Dakota. Next week a few posts on research presentations from AERA.

Knowing Your Role

This from the “Thinking Stick” – “I don’t like learning alone!”. Jeff Utecht comments on not being able to get into the conference scene. “Other than my own four sessions, I only went to two others …”. “I don’t like learning alone!” This post seems to have attracted some attention and comment. Perhaps it speaks to what the growing number of conferences have become, perhaps it speaks to something else. We do seem to have a proliferation of gatherings and some dissatisfaction with the experience. I do think there are too many conferences that seem to rely on the same presenters. I agree that this combination of frequency and redundancy is kind of boring. However, I am addressing a different issue here.

We may have just discovered another learning style or individual difference to add to the list educators need to address. Perhaps this difference is related to how many times a year you get to do this thing, i.e., go to a conference. Contrary, to the position taken in the Utecht post, I enjoy a “quality presentation”. I want to listen carefully and attempt to understand. I do not want to be distracted by “discussion” until the presenter has had the opportunity to offer background and provide a complete, well thought-out analysis. I do not want to offer three examples of whatever every five minutes to the person sitting next to me. I think I value depth over breadth – isn’t that the in thing to value lately. Until I can gain some insight into the depth of the position, data, or strategy someone else has to offer, my immediate reactions should be surpressed.

I like a quality handout and even a paper with additional information. If you presentation is really useful, I want to think about it some more. I may want to read the references you provide.

I guess we all have our opinions. Quality evidently means very different things to different people. My reaction to most spontaneous interaction depends on the intent. Most I regard as chit chat and banter. If it is intended as socializing, it is fun. Sparing with ideas is something I am capable of doing. It is entertaining. However, if the situation is intended as as an opportunity for learning, then the chit chat to Me is boring.

I think it is the combination of depth and interaction that is useful. There is a time to listen and a time to speak (this is starting to sound biblical). Take the time to read the book. Take the time to listen to a 20 minute presentation. Take the time to carefully prepare a handout. Understand a position and its context before you offer a comment. We get to play many roles if we are willing to be patient.

Exploring An Event In Flickr

I get a lot of ideas for educational applications from my own learning needs. We have been in the midst of a serious flood threat in the Red River (Fargo, Grand Forks, and surrounding communities). This is not the first time for us. We were here for the flooding of Grand Forks in 1997. I am writing this as the flood approaches the crest and how this will turn out has yet to be determined. Fargo is experiencing record river levels, but so far the dikes are holding.

I take pictures in situations like this. This is a serious situation and being obnoxious about taking pictures can get you in trouble. However, these are events that shape our lives and so I collect images when I can. I put a few of these images on Flickr and in doing so I notice that my Flickr account has received considerable attention in the past few days.

grabeflickrgraph

When I examined the images that were being viewed, it turned out they were from the flood (most actually from a less serious flood in 2006). This became the starting point for my exploration of the images that were presently being collected.

I explored in a couple of ways and I am certain there are several more. You can simply search by tag and then use recent.

flickrflood

I geotagged most of my contributions so I also tried searching for images by location. The best strategy seemed to be Explore a place (Grand Forks) and then search this map using a specific term (flood, redriver).

flickrfloodsearch

Most of the geotagged images I located were associated with bridges. This is where I have taken most of the pictures I have collected because access is not prohibited.

P.S. – Presently the rise in the river has slowed because of very cold weather (single digits at night). This has delayed the crest, but has allowed some of the water to move through with less risk.

1:1 Initiatives – Not Much to Report – Wait Maybe There is Something

I happened across a recent article on 1:1 laptop programs by accident. A post from the National School Boards Association referenced a recent article in in the prestigious journal Science. The first issue of 2009 was devoted to technology in education and there was an article on Laptop Programs (Zucker & Light). In the end, I must say the article was pretty generic. While a prestigious general science journal, I forget that the topic discussed is something those of us focused on technology integrating read at every opportunity so I encountered nothing I felt was a great revelation. I was hoping that someone had new and impressive data to report.

Perhaps the one paragraph I found helpful focused on a 4-year longitudinal study being conduced in Texas. Most work in this area must rely on samples of convience. The Texas study includes a large number of schools with laptops and matched schools without such initiatives. It takes money and the right circumstances to do research on this topic. Unfortunately, the study found no impact on reading and writing performance and perhaps a slight advantage in mathematics. In addition, the study determined that “the availability of computer technology by itself had little or not impact on the intellectual challenge of teachers’ lessons.” Such conclusions seem all too common. I am going to have to attempt to locate the Texas study (not published in a journal as far as I can tell from the Science article). My question would be did the laptop initiative focus only on the equipment and how to use it or was there a plan for curriculum reform that teachers ignored or found impractical.

BTW – the reports from the Texas Immersion Pilot work are available. I do note that the achievement data from the 4th year of the study is a little different than that reported in the Science article. One indicator of some unique interest is something called “home learning” –

For Cohort 3, the extent of Home Learning was a positive and statistically significant predictor of both TAKS reading and mathematics scores.

I think this makes sense. Perhaps simply finding ways to engage students to extend time spent will produce changes.
