530 Week 5
Sunday, November 21, 2010
Scatterbrained thoughts after Week 4:
See if you can follow all of the tangents I go on. The good thing about it is, if you have to comment on my blog, I’ll give you plenty of different topics from which to choose.
It’s kind of strange, the way I am looking at the world after being in these Stritch classes, especially Digital Storytelling. I find myself being more aware of all the stories that are constantly being told around me…
My wife and I just subscribed to AT&T Uverse. Part of the package that we received includes some premium channels. As of yesterday, we are receiving even more channels as some kind of promo. It’s just what I need, more channels/distractions. I haven’t mentioned that I am a TV junkie. As I do homework, I like to have something on in the background.
Since we have a week off from class, I woke up this morning (Saturday) and thought I could channel surf the 300+ channels now streaming into my home and find at least one worth while thing to watch. I found one of my favorite movies of all time, “Patton” with George C. Scott. As I watched, I thought, here is a great digital story. It may have originally been put to film with analog technology, but as true as I sit here, it is streaming in as “1’s” and “0’s”. During the film, at critical points, there is this recurring music made from what sounds like a marching band or parts thereof. This music gives a “joyous” and “happy” mood when things are going well for Patton and the American Army. The same score is played in the minor or flat notes and yields a “sad” and seemingly “haunting” mood when happenings do not go well. It is a powerful use of repetition and mood enhancement, I thought.
As I was watching some of the college football games today, there was a story the announcers brought up about one of the student athletes being adopted. This was after his father abandoned him and his mother passed away. I wish I had heard the whole story.
It even occurred to me that commercials in between and interrupting programs quite often tell a short story. This had occurred to me before, but never so resounding.
Gotta go! Another story is starting, “The Hurt Locker”.

Cooperative Learning and Reinforcing Effort
A few years ago, I created an assignment that involved students cooperatively building a bridge made of popsicle sticks, string, construction paper and elmer’s glue. The ultimate goal of the assignment was to show students how algebraic formulas work and what factors (variables, mathematical operations and their locations in the formula) influence the output of the “bridge equation. So I developed a formula that I thought encompassed all of the parameters. In a flash of inpiration, I included an aesthetic multiplier in the formula. This aesthetic multiplier was an average of a rating each student assigned to a finished bridge by secret ballot.
I arranged students in groups of 3 to 4 members. One of the problems that I encountered was too few jobs for too many people. What I mean by that is, I found in some of my groups the vast majority of the work was done by 1 or 2 of the group’s members. I enacted this lesson in a class that some students have excessive absences and I although I clearly spelled out the points awarded to the group for the finished product, I did not address how individual grades would be affected by absence(s).
Where the assignment was effective:
In the formula that I developed as the assessment tool, I placed the length of the bridge (minimum 24 inches) and the load (weight in pounds) it could support “cubed” in the numerator and the number of popsicle sticks “squared” times the number of bottles of glue “to the fourth” times in the denominator (I didn’t buy alot of glue and did not wish to have the students douse their bridge with glue prior to presenting to the class, a practical lesson in the cost of materials). The students were witness to how the materials in the denominator (to various powers) would detract from their “bridge index” and how strong their bridge was and its length would increase the index. Before construction began, I introduced the formula to them and gave them example numbers to “plug in” to the formula to see how the output index was calculated. After showing example pictures of bridges I stressed how aesthetically pleasing the bridges were. One of the best outcomes that I did not foresee was how honest (and critcal) the aesthetically pleasing factor played out. The ratings by secret ballot were from 1 to 5 with 5 being the most pleasing to the eye. The ratings were very uniform even when the students rated their own work.
The stress test was an exciting day for the groups presenting as well. I hung a 5 gallon bucket with dumb bell weights from the center of their bridges to find the maximum load sustained by their bridge. The student were witness to how their efforts and attention to detail in construction paid off in finding the critical load and ultimate failure of their bridge.
Where the assignment broke down:
Since individual job titles were not defined or assigned, I did not account for how the students would be individually affected by lack of effort or absence. If and when I choose to use this lesson again, I will have job titles assigned by the group’s members and address the absence issue. Clearly defined titles, responsibilities and an individual post stress test evaluation form will promote active engagement and learning by all.

Feedback that Fits and Strategies Reactions
Saturday, September 11, 2010
Some thoughts after the 1st night of class and the Meta-Analysis
I will admit, somewhat reluctantly, that while taking classes to become certified to teach, I looked at most of the information as a lot of “fluff”. With phrases used, like “every student can learn and succeed”, I said to myself, “Yeah, yeah, give me something I can use”. I don’t know if I have reached a turning point, but some of the information I now read, which is related to improving my strategies and techniques, is beginning to make more sense.
Two points resonated with me as I taught classes the 2 days after the first class of CEdo525. Those are: 1) the best way to improve student understanding of material is to show similarities and differences to what they already know. 2) communicate not only what the goals are for the entire class, but from day to day.
With so many great ideas to consider of how to introduce myself to students and what to do the first day, I wish I had read the article the week before school started instead of the week after.
Quite often - in years past - after being done with a class I have “taught” I felt like I went through the motions. This year I am becoming more cognizant of what I need to improve upon. It seems so obvious in hind sight that I haven’t shared the daily goal often enough with my students.
After reading the Meta-Analysis (and before reading the intro to Using Technology with Classroom Instruction that Works):
Keep in mind upon reading the following that the book intro explains some of my misunderstanding below:
If reading this article and posting a response was a means to “find a cynic”, here I am. I prefer the term "skeptic", however.
From the abstract:
“…The mean of the study-weighted effect sizes averaging across all outcomes was .410 (p < .001), with a 95-percent confidence interval (CI) of .175 to .644. This result indicates that teaching and learning with technology has a small, positive, significant (p < .001) effect on student outcomes when compared to traditional instruction.”
and
“On the other hand, the mean study-weighted effect size for the 3 studies that contained behavioral outcomes was -.091, indicating that technology had a small, negative effect on students’ behavioral outcomes.”
What is the study-weighted effect size, what does it measure?
I get the feeling spending all the money that districts do on computers isn’t justified if the results show just a “small” positive significant effect. I wonder what spending the money to hire more teachers, thus, changing the class sizes would do in comparison? And just what does a small, negative effect on students’ behavioral outcomes mean?
What was measured?
The article also states:
“Swan and Mitrani (1993), for example, compared the classroom interactions between high school students and teachers involved in (a) computer-based instruction and (b) traditional instruction. They found that student-teacher interactions were more student-centered and individualized during computer-based teaching and learning than in traditional teaching and learning.”
Am I missing something? The preceding sentences from the article state something that is as obvious as the following. Let’s say you only eat food with a knife and fork. The more you use the fork, the less you will use the knife…
Am I cutting my own throat here?
A couple of things I had to research and/or look up: Meta-analyses is a big study made up of a bunch of little studies (which by the way, the article says originally 200 little studies were retrieved and only 42 of them were used, the others were thrown out for various somewhat ambiguous reasons). Effect size is the output of a meta-analyses. It involves a weighted average based on sample sizes of the smaller studies. (How is the weighted average set up? Who decides how to weigh things? Or is there some agreed upon way? And what about those studies that were "thrown out"?)
The last paragraph of the conclusion is:
“There are, of course, many unanswered questions about the effects of teaching and learning with technology on students’ outcomes. We maintain, however, that research can play a critical role in answering some of these questions. Policymakers, however, will need to invest more money on research in technology. The findings from this research synthesis suggest that more and better research needs to be funded and conducted by researchers in this area. Although recognition of the uniqueness of each school and classroom situation will always need to be considered, the accumulation of research evidence over time and across studies may provide consistent findings that enhance our understandings of the role of teaching and learning with technology.”
What I read between the lines:
unanswered questions = disclaimer so if part of our study is disproved, we are not responsible
Policymakers will need to invest more money = We need a new study cause this one is over and we’re out of grant money (kinda getting hungry)
…findings from this research synthesis suggest that more and better research needs to be funded… = We don’t want to eat at anything less than a 4 star restaurant.
Having been an analytical chemist, I know how to use statistics to prove something. I am well aware of what the 95% confidence interval means, that is, within ±2 standard deviations of the mean (95 out of 100 times the next bit of data will fall within that interval). I have no idea, since I didn’t see it specified in the meta-analysis, of how it is justified that technology integrated in the classroom is better than without. After all, how are students from the
I do, however, believe students can achieve more with technology, but how much technology? Yet another study...

As always, A LOT TO SAY...spreadsheets, my history with them
I remember being introduced to Microsoft Excel some 17 years ago. I was shown the application [in Excel] of using “linear regression” to calculate the concentrations of analytes, mostly heavy metals, in effluent water and/or industrial waste produced by the manufacturing of heat exchange products.
I was a lowly worker in a laboratory, with the title, “Chem Lab Tech
Up to the point where I began to see where statistics truly has a purpose, I hated it. (In this regard, I can relate to those students who I am charged with teaching some specific topics that they hate.) The reason I hated it so much is that I didn’t understand it. What do you mean once I get an answer, I can only be 95% sure of its accuracy? And it lies within a window of this accuracy? That answer is an “outlier”! What? I don’t get it! As far as stats was concerned, I wanted to be the outlier!
Excel was enchanting to me; it took the data that I was generating from some expensive piece of analytical equipment and magically changed those numbers into useful answers (in a matter of microseconds, instead of hours of me punching the numbers into my calculator – God forbid, if I would have had to “crunch the numbers” by hand). It told me whether or not to tell the environmental engineer in charge of the plant, to keep the lines running or shut them down. Ah, what power I had (at least, in my own mind)! It was there that I finally understood the concepts of confidence intervals, variance, degrees of freedom, correlation coefficients and outliers, etc. I was finally an “inlier”! I had arrived.
I need to find ways to excite my students, energizing their motivation to become as passionate and enthusiastic about mathematics as I am. In this manner, I wish to show them applications involving computer and other technologies as the springboard. Utilizing spreadsheets was a turning point for me.
I have already used spreadsheets to show students the amortization of a bank loan, the maximization of the volume of a cylinder and right rectangular prism with the amount of surface area being held constant, the generation of the number pi by adding sides, ad infinitum, to a regular polygon and calculating the perimeter to pseudo-diameter ratio, graphing polynomials, in particular, parabolas to find the “zeros/solutions” and vertices, etc. all by using Microsoft Excel. Every time I have used these lessons, I have gotten overwhelmingly positive feedback from my students. I need to create/find more resources for these type of activities.

1st Blog of 515
Having read only the first chapter in the book, I have to get accustomed to some of its nuances (and in my initial opinion, faux pas) in order to acquire what is really being said. In other words, I had big problems, at first, with some of the ideas being stated. In particular on page 16 entitled, “Teacher’s Role” – focus is now on student learning, instead of teacher teaching (Huh? What kind of psychobabble am I reading?) I thought for something to be taught, something has to be learned. But after much contemplation, I have to agree with the book. Most of the time I spend planning for instruction, I am focused on what actions I will perform and statements I will make, rather than, how the students will respond and demonstrate their understanding. I could do my thing in an empty classroom and call it teaching, but no one is learning. I have more and more empathy with each passing year of what my students must be thinking when what comes out of my mouth sounds like some of the things I read earlier without time to reflect, critique, analyze and process.
I took the true/false quiz before reading the first chapter to see what I knew or thought I knew prior. I was shocked when I found the answer being sought for number 7, “According to this text, learning occurs best when it is technology driven”, was false. (“Technology has not been shown overall to be effective at increasing student achievement”, pg 13) Although, the text does throw a few disclaimers out there to justify itself and seemingly contradicts itself in the 4th line of Figure 1.6 pg 16 (“Technology can help make learning more effective by providing a great wealth of resources and allowing students choices). I guess it depends on the definitions of the words “overall” and “help”.
I really got a kick out of the heading “What is Learning?” on pg 9. Upon reading something like this, I believe most of us would formulate a quick definition, then read further, to see if we were right or maybe close. The book never defines learning in its following lines of text. It just makes mention of two theories of what it is and that is given in Figure 1.2. It does, however, say it will be addressed in chapter 2. What a teaser!!! (I think I focused on this since I gave a definition in class and wanted to see if I was close or way off.)
These examples and some others will definitely impact my job, in that, I will be more aware of giving time for students to reflect, critique, analyze and process information that I present. I have been guilty in the past of not giving enough “lag time”. I also need to concentrate more on asking a student or student(s) to “play back” what was just proffered by me and articulate to the class the information (I attempted to convey) and its usage (so that I can assess understanding or any misunderstanding).
Post Script – The answer I gave for #7 true/false was supposed to be “true” after all. I found out when I submitted my answers to be corrected. I don’t agree.

The last blog for 510. Instructions: What did you learn?
There are too many tangents I could go on to list everything that I have learned in 510 and upon completing and publishing this entry I am sure I will think of a few more.
So I will try to limit it to mentioning a few things that were most impressive to me:
Operating systems:
I was ecstatic when I learned of the different operating systems that I could download for free. My old “Compaq” will have new life. I can’t wait to have the time to play around with “Ubuntu” and “Linux Mint”. I may partition the hard drive to use both. I now refer to that computer as “Lazarus”, that is, back from the dead. I had heard of different operating systems, like OS 2 Warp from years ago (from IBM?), but never tried to learn anymore about them since I didn’t know enough or whom to ask. Now, I don’t have to ask anyone. Knowledge is liberating, indeed!
Tearing apart my old computer from ’94 was therapeutic as well as educating. I looked at the CPU with its built in fan and “heat-sink” design and it brought back some lessons learned from taking Physical Chemistry and working at a company that dealt in “heat transfer” years ago. A great deal of heat is generated from current running through millions of transistors. It is an enemy of the productivity and efficiency of the CPU.
I have more of an understanding of Malware. I used to be cynical about buying anti-virus software when some can be found for free. The features, efficiency and thoroughness of the software is definitely an issue here. I was excited to read independent reviews and find the software package that I will be purchasing. In researching the security assignment, I now know the steps to take and in what order to make my system and network safe.

Knowledge of a Computer's Inner Workings
Why is it important to understand my computer’s hardware and boot up sequence?
The whole “blue ray” technology allows more memory to be stored on the finite area of a disk. To my understanding, blue has a smaller wavelength than red and therefore uses less space. I believe the next big thing could be ultraviolet lasers to store and read memory. Ultraviolet has an even smaller wavelength than blue. Does the color of the ray need to be in the visible spectrum?
Quite possibly the resolution of the latest cameras have gotten too good and consequently causes the digital files to take a lot of memory. This might cause someone to try to upload files that take an incredible amount of time, when the resolution that they took their pictures at was overkill. This happened to me last night. I watched my computer try to upload a file that was 111 MB, that’s right 111 Million Bytes. This took over 2 hours. When it was done the location to which I was uploading said the file was too big. I don’t know why it didn’t tell me as the 2 hours started and not when it was done. This may not have the most to do with the inner workings of my computer, but it is on my mind now. Thankfully I have a wife who knows quite a bit about imaging software and she was able to scale down the sizes of my pictures, thus making the powerpoint presentation smaller and “uploadable”. Consequently, I was able to get my assignment done on time. A little more knowledge about the relative sizes of files is now in my memory bank…

My Computer Experience (in a nutshell)
The first computer class that I took was Basic Computer Programming in high school. We worked on TRS-80’s (Tandy from Radio Shack). I can remember writing short programs that would do some redundant operation. I was very impressed, but I didn’t see that computers would encompass all that they do today. It is one of my biggest regrets that I didn’t get a degree in programming (along with my math degree) or at least try. I found programming to be so logical. Some memories include “swap routines” and “dimensioning arrays” and trying to figure out what was happening with the data that was being input to a 4 dimensional array (I recall a friend telling me to envision a row of Rubik's cubes with drawers in each dimension of each cube, it worked!). I still find myself writing programs to calculate data for tasks that I perform often.
I want to take Visual Basic and Java classes to be able to program on 64 bit computers like I used to on older computers. I have put together some Excel spreadsheets that will generate some problems and results that I use to test students understanding of concepts, for instance, 2 by 2, 3 by 3 matrices, lines, parabolas and their solutions/characteristics, etc. I have also written some spreadsheets that calculate information for golf leagues and outings. The limitation in these spreadsheets is that they are “static”. I wish to have some programs that are “dynamic”, in other words, the programs will ask the user for occasional input and process his/her answers leading him/her to some subroutines (applets?) that will further the results that he/she is looking for. I have tried to learn some Visual Basic on my own. I experimented with macros, but only slightly. The problem that I encountered was the computer that I would run the macro on sooner or later would give some warning as to the possibility that my macro was a “virus” and would ask for the administers password or would not run the macro altogether.

Frustration
I believe one of the most frustrating things that I am encountering as I enter this new “cyberworld” is trying to find everything. I feel like I am blindfolded and stuck in a maze that I have never seen before from the outside and trying to make my way around. I can’t remember where the “room” that I was just in is in relationship to everything else or how to get back to where I was a moment ago. I guess I would be showing my age and how “old school” I am if I were to refer to the “trees” with the roots that were once used to display the directories and file locations in the old “MS DOS”. That I could visualize to perceive where I was going and where I had been. I am sure that I am not being efficient nor going into an application in the same manner as others. For example, I am opening up new tabs all the time in my Chrome browser so I don’t lose one application as I want to view another. I am opening a new tab and typing in blogger to get to my blog (thank goodness I chose the option to save my username and password). It’s not like I didn’t have two-thousand of those prior to taking this class and am now finding myself with at least 5 more usernames and passwords.
Just a quick list of the organizations or entities I can think of off the top of my head that I need a username and password/code or pin # for prior starting this class:
My School District Web Site which includes 3 separate Usernames and passwords for:
Attendance and Grade Entry
Group wise Webmail
Subfinder
My online banking
My credit cards
My cell phone website
My cell phone security code to access voicemail
My Yahoo account
My online tax filing service
My pin number for accessing records of previous tax returns
My pin number for “ATM”
My log in for each of my two laptops
My password for the “router” (which I have no idea how to change anymore)
My keypad to open the doors on my truck
I am certain I am overlooking some.
New Usernames and passwords after joining this class
Wolfmail
my.stritch the same as Wolfmail?
fafsa
my blog
gmail
The last 30 lines or so is therapeutic for me. It is my way of venting. It reminds me of what a very close and wise friend said to me recently, “How do you eat something as big as an elephant?”
Answer: “One bite at a time”.

Old Habits Die Hard
I am currently typing this in Microsoft “Word” and will soon copy and paste in my blog. It is another indication or should I say self-realization of how comfortable I am in “Word” and fearful of the unknown. I hope I am able to do it. It is reminding me of why people are afraid of change and therefore brand loyal. The reason I keep buying a Ford vehicle. The reason the incumbent candidate is voted in over 90% of the time. The reason Microsoft only had Internet Explorer resident on so many computers and the reason it still holds over 50% of the market share. It is also the reason for the antitrust action against IE. I plan to write my 1st paper in Google docs shortly. Good bye old friend. :(
