I have written about 20 recommendations this school year, so I thought I would share my “requestionnaire” for students. I ask them to answer these questions so that I can get to know them better and then write a more thorough recommendation. I have learned a lot more about my students through their requestionnaires!

Recommendation Request – College

At least three weeks before your application due date, please complete the following request.

Email your answers to Attach an updated copy of your resume. Make sure it includes school activities (sports, clubs, arts, etc.), awards (academic, athletic, fine & performing arts, community, etc.), and community organizations you are involved in.

1) Describe your college/career aspirations or goals. List all colleges to which you plan to apply.

2) List your numbers: G.P.A., SAT (Math, Critical Reading, Writing), SAT II, ACT.

3) List courses that you are currently enrolled in.

4) List courses you had with Ms. Buenafe [and new for 2013-2014: why you chose Ms. Buenafe to recommend you–did well in her class, math is your strong suit, Ms. Buenafe knows you well, etc]

5) Explain what you’ve learned from your experiences (employment, community organizations, after-school activities, community service projects, etc). What did these experiences mean to you? How did you grow and change as a result?

6) Please list something special or unique about you and explain (e.g. play musical instrument, reading, interests, hobbies, experiences, etc). What sets you apart from other JQUS students?

7) List three adjectives that describe you and explain why.

8) Write an example of a comment a teacher might make about you (not a report card comment).

9) Describe and explain one or more academic accomplishment(s) in which you take special pride.

10) Describe your family (occupation of parents, discuss siblings, and special circumstances).

After I approve your recommendation request, please add me as a recommender on Common App and send me any non-Common App recommendations you need.

for the smile file

By Kristina

I save nice notes from my current and former students in a “smile file.” I’m going to start adding tidbits such as this one as well. Several people came up to me after I “judged” a few startup pitches at the December EdTechup, and they complimented my insights and perspective (including the kind fellow from the above tweet). It was really nice to feel like a valued professional and to have my voice heard. Sometimes I forget how easy it is not to interact with other adults during the school year!

The Net really did come true

By Kristina

Ordered pizza for my intern’s last day. I can track it as it gets made…so cool! To think, back in 1995 when Sandra Bullock ordered pizza in the movie The Net, we all scoffed and said it would never happen.

I will definitely use Domino’s for pizza parties from now on. Ordering online is so much smoother than calling the pizza places down the street after reading their menus online.

We started exponential functions today in IB Math Studies. The students attempted to guess the population of the U.S. and the population of the world. Surprisingly, most students guessed way over (about 2 billion). I showed them a clip of the Contagion movie trailer and had them write down the numbers spoken by Jude Law (so that they’d pay attention to the math rather than just the ominous nature of the movie), then see if the pattern matched up with his prediction of 1 billion deaths in 3 months, like in this MathsPig post. Some students asked “are you doing this to scare us away from bird flu?” I wish I had addressed the other factors that affect disease transmission at this point. Would 1 billion have been realistic for three months given geographic location (i.e., more time to transmit from continent to continent) and any slowing in disease transmission (i.e., if people were quarantined)?

We moved on to our Disease Detectives activity (based on this lesson from Georgia Southern University). I borrowed NaOH, phenolphthalein, graduated cylinders, and beakers from my science colleague in the room above mine.   During pre-class setup, I ended up rushing a bit because I had to fill the graduated cylinders with water from the cafeteria sink (the science sink water was cloudy ) and make handouts. I wouldn’t have been able to do this if I had a first period class.

The Setup

I handed out cups of clear solution to all the students, informing them that one student was “infected” (aka Gwyneth Paltrow in Contagion). I instructed the students to interact with two other students by mixing liquids and keep track of the students’ names. Then came the big test: who would be infected? I went around the room with a spray bottle of phenolphthalein to test each cup. The students waited in trepidation, and as soon as the first infected cup turned bright pink, they started screaming. I recommend using clear cups for this…it’s more exciting to see an infected one turn pink. During this round, four students were infected. I had them try to figure out who the original infected person was, but they couldn’t. Neither could I–I didn’t track the infected cup when handing it out.

Uh-oh…someone at this table was infected. Will the next person be too?

After round 1, we had the Great Spill of 2012 when trying to dispose of the liquids. I was hoping to carry them up to the science teacher’s classroom with a Halloween candy bucket, but the bucket started leaking all over the table. We lost about 10 minutes of instructional time sending students out for more paper towels, sacrificing a running trophy to catch the leak, mopping up the spill, and sending students out to wash their hands. However, the students were good sports and we still managed to do another round with three interactions. I forgot to have them estimate the number of students infected, so after we discovered 7 infectees (some of whom started screaming as soon as they realized they had traded with the first person whose cup turned pink), we looked at the theoretical numbers. In round 3, there should have been 8 infected people, but as my intern pointed out, the lower number could have been caused by two infected people trading.

Infected students in Round 2

I enjoyed doing this lesson because of the hands-on, visual aspect and the connection to real world issues. A few years ago, there was a swine flu outbreak at our school, so the issue of infectious disease transmission is very interesting to us.
