Final Project Reflection and Kim's Keynote Address
Laptops in the classroom
Laptop (and sometimes desktop) management has been a tricky issue for me, and I know that at times my students have gotten away with all manner of distraction when they were purportedly working for class.
I use laptops for various purposes in biology class. They are used for collecting and analyzing data using data-logging tools and probes. Students rarely get off task during a lab situation. Their time is simply too limited and they won't have access to the data-logging equipment outside of school, so they have a high motivation to finish within the allotted time. Many students are also naturally engaged by the hands-on aspect of experimentation. Of course, I walk through the room to check on student progress, but although they may need assistance they will not be distracted by facebook and so on during a lab.
Cyberpolarization and the dangers of getting what you want
Who knows what they're learning?
How do we get 21st century learners?
This week’s essential question is, “Whose job is it to teach the NETs and AASL standards to students?”
Reading the technology standards from ISTE’s National Educational Technology Standards for students and AASL’s Standards for the 21st Century Learner was very interesting. Although they approach the standards from different angles, with ISTE focusing on specific types of technological experiences and skills by developmental level and AASL centering on overall skills and dispositions of the ideal learner, they both emphasize the importance of developing judgment in students. This applies to the content of their work as well as their use of technology, in selecting tools and using them ethically.
Many of the ideals promoted by these documents are in no way limited to technology, and it is certainly our job as educators to provide these types of experiences and instruction. Young people (at least, those with a privileged background such as attend our school) are working with information technology from very early ages. They know many ways to approach innovations in technology, but this does not guarantee the development of good judgement, or even competence in skills. Even in the exploration of the simple capacities of IT, students may only consistently develop proficiency in those areas that interest them. They know endless details of Warcraft and iPhone applications, but using a subscript for a chemical formula in Word can stump them.

Course 3 Final Project Reflection
The whole process was very interesting and full of little bumps, so it was gratifying to finally achieve a product at the end.
Before we began recording, Karen, Harvey and I made a storyboard for what our video would look like. There are dozens of issues that arise every year when students begin working with microscopes, but we decided to choose only a few. It seemed a better plan to do tackle a few issues and have time to edit them effectievly rather than try to do everything and end up with nothing, especially since we originally intended to complete it in a single class.
Karen played the responsible student, I played the careless one, and Harvey was the teacher and the videographer. We tried to be a little silly so that movie would have some humor for the students - that was fun. We used one of these little video cameras (flip?) - they look like still cameras and have only a few buttons. We found out that it doesn't take still images and has a very limited zoom, so we had to zoom by actually moving forward. Also, the camera wasn't charged so it was very alarming to see the red battery light flashing every time we filmed a clip. We got the footage we had planned for and attempted to begin editing.
We tried to import the clips into MovieMaker, and it went through the process which took a few minutes, and then said "There was an error with 36 of 36 clips." We tried again, and then we tried in iMovie. Again, no luck. Finally we realized that the format of the clips (mpeg-4) is not supported by either program (in its current incarnation, anyway.) We had begun researching the fastest way to convert all of the clips when class time ran out. That's when I picked up the idea for my final project.
Luckily, I still have the old version of iMovie on my personal computer at home, which I knew supported mpeg-4. It's a lovely, comfortable program that we've used to edit many a family video. Unfortunately, the computer is now over 5 years old - it took the better part of an hour to complete the import, but hey, it worked.
The footage was limited, but it was fun trying to make it fit together. I made stills from the clips and reused some footage that was too short. I used captions rather than audio, with red for poor choices, green for good, and an orange for neutral information. I used creative commons to find background music. I searched for classical and on the first page found some piano and guitar (among my favorite instruments) that fit in well with the timing of the film. I downloaded a few audio effects, as well.
It took a few hours to get the audio and fit everything together. When I finally converted the video and posted it on youtube, I was satisfied with the product. I showed it to a few colleagues, and they think it's clear enough to show to students. We'll see!

The Explosion of Digital Video
With the explosion of web based video, many things can be visualized that could only be described previously. Here is a video showing the surface tension of water in a fascinating example:
Further, advances in video technology can show, including time lapse, pinhole cameras, and so on can show all sorts of processes never before possible. Here is a clip from the outstanding video series "The Private Life of Plants" with Sir David Attenborough.
All of these videos no longer have to be sourced long in advance as part of the school or department library. Rather, they can be found and streamed so quickly that they can be used to demonstrate a phenomenon as it comes up in discussion, or at latest, in the following class (because of course one sometimes wishes to sort through the options to find the most effective videos).
In biology, there are few things as powerful as vivid imagery as seen in photo and video. They can express clearly and memorably very complex ideas. In that way, they are a great advantage in the biology classroom.

Digital Storytelling
We had a fantastic time working on creating a visual story to go along with a story told by Utah Phillips, a labor activist and folk musician.
One interesting facet was effectively dividing the workload so that four people could be productive at the same time. This worked well during the image-gathering stage but was less effective when we began editing. Also, when we were searching for images, some people got distracted and ended up watching videos of people getting kicked in the testes (let me use the biological term since I do teach biology) for quite awhile on youtube.
I edited the original image times to match up with the story on iMovie. This version and some of the images we collected were later lost, so John was nice enough to put something similar back together for us. Since we had limited time, we were only able to get the pictures to align with the story about two-thirds of the way through. It was very obvious when the pictures and words became out of synch, and it was therefore very interesting to see how much information was conveyed and how powerful it was when the images and audio did work together.
Another interesting point was that different people felt that very different images were key to conveying an idea. Some people were more literalist, wanting images of strongmen and martial arts to represent a powerful blow, while others tended to more abstract representations of power like lightning and tornadoes. It was a good way of bringing into focus the important of knowing an audience, what associations different images are likely to have, and to what extent these assocations can be considered common or "universal" within an audience.
This storytelling approach could be taken in some of the more creative projects in biology. For example, some students benefit from taking a complex process like photosynthesis and making the parts into characters, and the steps into a story. Narrative is of course very powerful, and a digital story could be made along those lines.
Visual Presentation Techniques
I use a large number of powerpoint presentations for my IB Biology classes. I started making them when I came to ISB and had a projector in the classroom. Before that, I used a variety of other presentation strategies, but the powerpoints were very popular with the students.
By student demand, I now have powerpoints for every bit of syllabus content. At first the presentations consisted primarily of images and some animations. The students, however, wanted to use the powerpoints as review tools and without the discussion that surrounds each idea and slide, were unable to effectively use them in that way.
I therefore began adding explanatory text, primarily for when they are using the powerpoints on their own. In fact, I sometimes skip slides in class, telling them that they can read them on their own time. For the majority of students this is a workable solution, allowing them the freedom to ask questions and discuss details without worrying about copying everything into their notes. Other students struggle, either because they try to copy down every word on the powerpoint anyway or because they lose focus knowing that they have a copy and can look at it later.
In the first case, the students do not engage in discussion because they are busy copying and also tend not to put ideas into their own words. This can prevent incorrect or imprecise wording in the short run, but reduced the depth and retention of important ideas in the long run. In the second case, valuable class time for sharing and actively learning is lost.
When I was redoing one of my powerpoints, I tried to further limit the text that I put on one slide. There is tension between keeping a process coherent and breaking it into small enough pieces to be presentable. The powerpoint ended up being much longer, with more repetitive images (part 1 of process A, part 2 of process A, part 3 of process A, summary slide showing parts 1-3 of process A, etc.) I'm not sure if it turned out better, but it was an interesting process.
Another idea was to put the text into the presenter's notes so the students can't see it during class but have access to it during review. I know this would make some students uncomfortable, but I plan to give it a try in a later lesson.

I used the Creative Commons image search to find the following image of an ant sipping from a drop of sugar-water:
This lovely macro can be useful in the biology classroom in many ways. Firstly, the picture can be used as an entry into the nature of pollination. The sugar-water the ant is sipping was placed there by the photographer, but it brings to mind nectar and the "exchange of services" between plants and their pollinators. The true nectar (or enticing scent) is likely to be located at the base of the flower, ensuring that the ant brushes the pollen-laden strands on its way to a sugary reward.
Secondly, it shows the surface tension of a water droplet and gives a sense of water's cohesion. At the scale of an ant, the three dimensional nature of water droplets in more vivid and real than what students ordinarily experience. The immediacy and reality of biological events can be conveyed very powerfully with images, and this is especially effective when they demonstrate things that students can't observe without the help of special technologies. This could be something on a small scale, such as the gorgeous diversity of diatom shells, or a large scale, like deforestation. It could be processes slowed down in time, like a basilisk lizard running across the surface of the water, or it could be processes speeded up, such as the amazing time-lapse movies seen in David Attenborough's "The Private Life of Plants".
Finally, these ways of improving our perceptions, seeing the detail and intricacy and "big picture" of life and living systems increase student interest and often instill a sense of wonder and respect for the things normally 'beneath' our notice, or beyond it. For students, this can translate into a greater overall connectedness to the world around them and the ability to think more creatively, from a broader perspective, and with greater insight.
Thus visual imagery is an indispensible support for my curricular content.
Another Spice in the Pot: CoETaIL's Influence on My Methods of Instruction
As educators, we incorporate countless sources of information into our instruction and make myriad choices about instruction.
Some of the sources of information we sift through each day in creating a coherent lesson include curricular goals, current news in our discipline, student and class dynamics including language proficiency and learning styles, and even the time of day or energy level when the students walk into the room.
Some of the choices we face daily include when to provide direct instruction and let students learn through exploration, when to encourage or rein in discussion that may meander interestingly off course, when to assess with "points" and when to take the pressure off, when to have student in groups and when they should work alone, when to bouy up students and when to have them take responsibility for themselves, and of most relevance here, when to incorporate the varied technologies at our disposal.
These choices read like Ecclesiastes - to everything there is a season. No one choice is right for all situations. A good educator must make judicious use of all this information and make effective, balanced, and compassionate choices that will help students learn content, become more self-sufficient learners, nurture their inherent interest, and also (I feel) make them more caring, competent citizens.
What CoETaIL has offered me is the chance to explore emerging technologies in a deliberate fashion and to improve lessons that are already good, even great, but which can now have a new enriching dimension that was not easily available when I started teaching 10 years ago. As a particular example, I am interested in students abilities to continue their discussion and explorations with each other outside of the class setting. Online communication among classmates offers many advantages, especially for reaching students uncomfortable with public speaking, or asking questions with everyone's attention on them, or who need longer to process and come up with good questions than they have during face-to-face classroom time, or who develop a sense of confidence from helping their peers; the list goes on.
I say adding ideas from CoETaIL to my teaching is like adding another spice to the pot. This is a better analogy than, let's say, adding another tool to the toolbox, because I can do more than simply solve one problem or complete a specific type of task. Incorporating new types of imagery, new methods of communication, new avenues of expression add richness and depth to the diverse and already-established methods of instruction. A teacher's bag of tricks is more than the sum of its parts; just as the flavour of a dish is more than the sum of its spices.

Reflecting on the AUP
For our final project, my group chose to rework ISB's Acceptable Use Policy (AUP) for information technology. We began with the school's current AUP, a well thought-out document written by our HS Technology Coordinator.
- A statement of philosophy regarding how information technology should be used at our school
- An educational document for members of the school community explaining in some detail how they can meet the standards of acceptable use
- A reference for determining disciplinary action when students use IT in unacceptable ways
- adding some technologies by name that are of concern to those working in the library
- adding more detail about how to protect others (not forwarding, publishing, or otherwise sharing information send in private without permission)
- adding a statement in the "consequences" section about keeping to the spirit of the agreement and making it explicit that students will be held accountable for their actions whether specifically discussed in the AUP or not
- replacing some weak language with clearer and more precise wording

The Power of the Web
This week's essential question is, "What makes the Web so powerful?"
Empathy and Education
Copyright revisited
Thursday, April 2, 2009
Copyright conundrum
This week’s essential questions are: “What is Fair Use?” and “What is the purpose of Copyright?”
The topic is incredibly complicated, and copyright rules vary from country to country. I was surprised to learn that within the US system and many others, there are almost endless circumstances under which there is no clear answer as to whether or not you’re in violation of law. As copycense.com points out, much of the information available is not accurate. Some companies want more protection than they are legally entitled to, and are not above “educating” the public in such a way as to increase their profits.
I want to do the right thing. I want to give proper consideration to the creators of the work. I want to give my students the best possible tools for learning. I want to feel confident in my understanding of the spirit of the law and the specifics of how it applies to me. So far, though, the whole thing just makes me uncomfortable. We have another class on copyright; hopefully that will get me closer to figuring this out.

Privacy Online pt. 4: Shades of Gray
Some areas are not as clear cut as credit cards (obviously private) or complaining about your boss on your blog (obviously not). Here are just a few of the gray areas:
I used to consider my emails private. (At least from my private account - most people I know don't use their work account for sensitive business. Not a great idea if they do - one funny example is seen in an episode of NBC's the Office called Email Surveillance.)
Then I got a google account and noticed that all the ads were related to text in the body of my email. I even wrote back and forth with a friend to see if we could bring up ads about the Smurfs. (We could.) That convinced me that really, the contents of my emails are not fully private. If I have a private conversation with my husband, it's pretty unlikely that anyone would could possibly care would find that information, but we never send information that might be exploitable by a stranger.
Another alarming move was facebook's attempt to retain permanent rights to use, modify, etc. anything you post online (subject to your privacy settings). This change was reversed, and facebook argued that it was just trying to protect itself seeing that some of your posted information could end up "on servers out of its control." The language of the Terms of Service, as seen in this important consumerist.com post, is not unusual for social networking sites and reads like one of those waivers you have to sign before you bungee jump that basically says that anything that happens is your fault, or at least not the company's.
So, the ultimate lessons we need to convey to our students are 1) There is little privacy online, 2) how to keep things private and protected will continually change and you need take responsibility and keep up with those changes, and 3) that's no reason to avoid being online, it's just a reason to be educated and judicious. They're not easy lessons, but we'll do what we can.
Privacy Online pt3: Unreasonable Expectations of Privacy
In order to pretend that your facebook profile is private, you would need to have only "friends" who will always know and share your interests, who will never post materials offensive not only to you, but to anyone in your life, who would never make an error of judgment, who would never pass on your posted information, intentionally or not, to someone less scrupulous. Not likely.
I think our students need to be taught about the wider audience that may see their posts. It is sometimes difficult, especially as a young person, to see ahead to the time when you wouldn't want people to know about your high school antics, so explicit instruction is needed at home and at school. I, however, feel it comes down to this -- if you post it, assume anyone can see it.
Privacy Online pt. 2: Reasonable Expectations of Privacy
Privacy Online: Three can keep a secret...
I found this post difficult to write. There are so many aspects to our lives online and so many variations on each situation, and I’m no expert on the details of what companies or cyber-criminals can do. I’ve broken my thoughts into several sections.
To quote Ben Franklin, “Three can keep a secret when two are dead.” Whatever you communicate online has a concrete form that can be archived, phished, or forwarded. There are always three involved – you, your intended recipient, and the Internet. While you could argue that the Internet is dead (or at least, non-living), it is also your messenger, your secret-carrier. If your information is likely to arrive unlooked at, it is not because it’s so well protected, but because it passes unnoticed amidst the sheer volume of other, similar information.

Digital Footprints
This week's essential question is: When and where should we be teaching students about their digital footprint?
Our face-to-face (f2f) meeting this week included Ms. Silvia Tolisano's fascinating presentation about the nature of one’s presence online presence, or "digital footprint". She emphasized that we have moved beyond the time where "digital invisibility" is a reasonable expectation for students... or even a desirable one.
Educators vary widely in their understanding of digital footprints and the emerging technologies that make them possible. Those "in-the-know" may offer advice or informal instruction, but these efforts can not be counted upon to reach all students. At my school there is little in the curriculum about online behavior other than plagiarism. Formal efforts to raise student awareness about digital footprints and cyberbullying include showing a video (see below) in which a hard copies of girl's picture are subsituted for the digital image, showing how it is impossible to remove.
This is a crucial lesson, especially for the younger grades, but is it, alone, the best approach? As with all social and global issues, we want children to understand the seriousness of our message, but we must not frighten or upset them so much that they shut the information out and ignore it. In this case, we must be careful not to engender a feeling of helplessness, especially in students whose social lives are inseparable from online media and who may not be willing to give up their online activites for safety. There is some evidence of this attitude. In his article on digital footprints and employment, Fields Mosley quotes a man who refuses to worry about his online footprint because, he says, it's beyond his control.
So, what about our students who have already made these indelible errors? What about those who, for whatever reason, are unwilling to curtail their online antics?
There are always steps one can take to improve one’s online image. In her online article, Kim Komando suggests (among other things) highlighting positive achievements online, encouraging links to these, and constructive blogging about one’s passions. This has the double benefit of showing off one's accomplishments and pushing any negative links out of the top search results.
How important is all of this to our students? A clearly written article in admissions.com cites Kaplan research showing that 10% of college admissions offices reported looking up applicants on facebook. Other social networking sites, googling, and so on are also commonly used by universities and prospective employers and the numbers seem likely to increase.
As educators, we should go beyond the teaching about the dangers of online life. Clearly, student safety is the first priority and these lessons have their place. However, we should augment our instruction with information about the benefits a digital footpring might have on college admissions or hiring. Imagine googling a young applicant to find not evidence of drinking and immature behaviors, but a blog ongoing involvement with a subject of interest like music, community service, or biology. One can easily imagine the extra boost such a result might give in the increasingly competitive admissions and hiring offices.
The place for these lessons is not as obvious to me. Some possible ideas include a few classes (perhaps in the freshman seminar my school offers) for early high schoolers on not just erasing or sanitizing, but estabilshing their digital footprint, along with all the safety instruction about identity protection, social networking behaviors, online predators and so on. The counselling office could work with all college-bound juniors and all seniors research and improves their digital footprints. Then the students would be empowered to make sure the image they're projecting (safely) to the world is the one they want their prospective schools and employers to see.
What's in a Name?
I have an artist friend and he sometimes takes a view which I don't agree with very well. He'll hold up a flower and say, "Look how beautiful it is!" and I'll agree. And he says, "I, as an artist, can see how beautiful this is, but you as a scientist take it all apart and it becomes a dull thing." And I think he's kind of nutty.First of all, the beauty he sees is available to me, too, I believe. Although I may not be quite as refined aesthetically as he is, I can appreciate the beauty of a flower.At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside which also have a beauty. I mean, it's not just beauty at this dimension of one centimeter: there is also beauty at a smaller dimension, the inner structure... also the processes.The fact that the colors in the flower are evolved in order to attract insects to pollinate it is interesting -- it means that insects can see the color. It adds a question -- does this aesthetic sense also exist in the lower forms... why is it aesthetic, all kinds of interesting questions which a science knowledge only adds to the excitement and mystery and beauty and awe of a flower.It only adds. I don't see how it subtracts.
