Spot GPS Tracker and Satellite Messenger

Love this gadget for my outdoor trips and just for peace of mind on the road. Hint: give it 20 minutes to uplink!
It is not a full featured Personal Locator Beacon, but very useful nevertheless.
For example you can easily geotag all your pictures simply by setting your camera time to GMT and after you come back home download .gpx file of your trip from Spot website into the same directory where you keep pictures of the trip. Now use GPicSync and photos are all geotaged!
You can even share your adventure on internet like this!
The original version of Spot GPS Tracker won 2008 WSJ Technology Innovation Award.
New updated version of Spot GPS Tracker and Satellite Messenger just hit on-line stores...

Brontobyte and rumors about Nisababyte

Here is handy table
1 bit = a binary digit
8 bits = 1 byte
1000 bytes = 1 kilobyte
1000 kilobytes = 1 megabyte
1000 megabytes = 1 gigabyte
One gigabyte of information - about a quarter of the memory of an iPod mini - is the equivalent of a pick-up truck load of paper.
1000 gigabytes = 1 terabyte
1000 terabytes = 1 petabyte
1000 petabytes = 1 exabyte
1000 exabytes = 1 zettabyte
1000 zettabytes = 1 yottabyte
1000 yottabytes = 1 brontobyte
1000 brontobytes = 1 geopbyte or is it 1 nisababyte?
1000 geopbytes = is what?
There are rumors on the web that
nisababyte is 1000 brontobytes and a zotzabyte = 1000 nisababytes.
Not sure about it... Any better ideas?

And those who insist that
1 Byte = 8 Bit
1 Kilobyte = 1024 Bytes
1 Megabyte = 1048576 Bytes
1 Gigabyte = 1073741824 Bytes
can use this byte converter.

Zeno's Paradox of Motion

The Dichotomy: There is no motion, because that which is moved must arrive at the middle before it arrives at the end, and so on ad infinitum.

The Achilles: The slower will never be overtaken by the quicker, for that which is pursuing must first reach the point from which that which is fleeing started, so that the slower must always be some distance ahead.

The Arrow: If everything is either at rest or moving when it occupies a space equal to itself, while the object moved is always in the instant, a moving arrow is unmoved.

The Stadium: Consider two rows of bodies, each composed of an equal number of bodies of equal size. They pass each other as they travel with equal velocity in opposite directions. Thus, half a time is equal to the whole time.
And the solution is ...

Interview question: "Tell me about Parent-Teacher Conferencing"

Why have Parent-Teacher conferences?
Report cards fall short in informing parents for obvious reasons.
You learn about student's parents
Best opportunity you have to cooperate with parents and to resolve any problems kid might have.
Learn more from this book: Teacher-Parent Interviews, by Grace Langdon and Irving W. Stout, Prentice-Hall.

Interview question: "What are three major class room rules for students?"

Another popular question: "What are three major class room rules for students? And what are consequences of violating them?"
Rule number one:
Rise your hand if you want to talk. You loose your turn to talk if you violate this rule.
Rule number two:
Follow the directions of the teacher the first time they are given.
Rule number three:
everybody in the classroom are to be treated with courtesy and no words or actions intended to cause anyone harm will be allowed.
Consequences
First Step - Verbal warning
Second Step - Hold after class for conference with teacher
Third Step - Parent contact, detention after school with teacher
Fourth Step - Referral to the assistant principal for discipline
Fifth Step - Immediate exclusion from class and referral to the office

Serious offenses like refusal to follow the instructions of the teacher or acts of violence will be immediately excluded from the classroom.

Good behavior and academic performance will be noted by:
Verbal praise - we all like to hear about it when things to well!
Phone calls to parents - calls from the teacher should not always mean bad news.
Positive post cards to parents
Fun days - days or time for student chosen activities.
===================
Ideas for Classroom Rules from Melissa Kelly

1. Come to class on time. Standing outside the door and rushing in after the bell has begun to ring will constitute a tardy. You must be INSIDE the door when it begins ringing to be counted on time.
2. Begin the start up activity within 1 minute after the tardy bell. Directions will be on the projection screen or the board. Please do not wait for me to remind you to begin since I need to take roll and attend to other duties for the first few minutes of the period. When I begin class, directions for the start up may be taken down, so don't delay.
3. Attend to personal needs before coming to class. I have been instructed not to give passes to lockers and to limit passes, so please do not ask for a pass unless you have a true emergency.
4. Remain in your assigned seat unless you have permission to get up . Throw scraps away at the end of the period on your way out.
5. Do not eat candy or other food in class unless you have been given special permission. School sponsored sales will be permitted during the last 5 minutes of class IF we are finished with the lesson and permission is granted. Be sure to ask first.
6. Bring required materials every day unless you are otherwise directed.
7. Talk only when permitted. Be aware of the situation since quiet talking is allowed in some situations and speaking to the entire group without raising your hand may be allowed in others. I will remind you once and expect compliance.
8. Use polite speech and body language. Unkind teasing and impolite behavior is unacceptable. Please do not ask to step outside to spit.
9. Do not cheat. Students caught cheating will receive a zero and a phone call home. Both the student who shares his work for an independent assignment AND the person who copies it will suffer the same consequences. I expect you to do your own work and to be sure no one can copy it.
10. Follow the teacher's directions immediately. Keep me happy and I'll do a better job for you!
========================
Or even better! Let students make the rules!

NSF funded Math Curricula

Elementary Curricula
ARC, the Alternatives for Rebuilding Curricula Center is a collaboration between COMAP, the Consortium for Mathematics and Its Applications and the three National Science Foundation supported elementary mathematics curriculum projects:

Everyday Mathematics developed at the University of Chicago.

Investigations in Number, Data, and Space

Math Trailblazers

TIMSS, PIRLS, NAEP

I keep discovering more abbreviations...
I wonder how these studies can benefit an average teacher...
May be if one chooses topics carefully test scores will go up?
NCREL, the North Central Regional Educational Laboratory has been developing an interactive Web site designed to assist school districts in their reform efforts of mathematics and science curricula.
Anyhow here are the links...
TIMSS, the Trends in International Mathematics and Science Study, is designed to help countries all over the world improve student learning in mathematics and science.
TIMSS Research Questions
1. How do teachers in different countries teach?
2. How do their instructional practices differ?
How do these differences affect learning?
What can we learn from this?
3. What curriculum differences exist among the countries?
What is taught and when? What is not covered?
4. What are the different social and cultural contexts with which this learning takes place?
5. How do these affect learning?
6. What lessons can we learn?


PIRLS, the Progress in International Reading Literacy Study is one of the largest international assessments of reading literacy
NAEP, the National Assessment of Educational Progress Often called "The Nation's Report Card"
You can get results of NAEP studies here.
And here you can get TIMSS 2003 International Science Reports.
The TIMSS Assessment Frameworks and Specifications 2003 is the publication that describes in some detail the mathematics and science content to be assessed. The document also presents a framework describing the contextual factors associated with students’ learning in mathematics and science.

Institute of Internet History - a non-profit, non-governmental, non-organization

Do you know what "ping" is all about?
According to Institute of Internet History also known as "non-organization" back in 1902 poor kids cleaning rusty pipes were called "pings".

To keep the rust at bay, network operators and service providers employed young boys, and sometimes girls, to run through the pipes with stout wire brushes to remove built-up deposits. These boys and the runs they made were referred to colloquially as "pings" due to the noise they made by tapping their brushes on the inside of the pipe at each joint to indicate their progress. The term "ping" is still used today to refer to a method of ensuring that a route on the Internet is available and not clogged.

Human brain held about 200 megabytes of information

Back in 1986 Tom Landauer concluded that the human brain can held about 200 megabytes of information. He got this number by estimating the rate at which people take in information and the rate at which people forget things.

And hard drive on my computer is 100 gigabytes! Now you see why title of my blog is "Things to remember"!

With about 6 billion people on Earth the total memory of humans now alive is about 1,200 petabytes. The Library of Congress is about 2-3 petabystes.

As far as processing power goes prof. George Miller estimated that our brain can handle five to nine thoughts at once. Read more about human mind

Teaching Philosophy

Detailed Statement on Teaching Philosophy by Andrew V. Knyazev who is with Department of Mathematics at University of Colorado at Denver. Here is his approach to testing:

I open each session with a brief reminder of the previous session's material and an outline of the day's topic, and I typically conclude with a summary of key points. There is a special session for review before every major test. I usually speak clearly, loudly, and slowly, but enthusiastically. Students are encouraged to learn from each other as their grades are not curved, thus, students are not competing with their classmates. In some classes, I give group projects and homework. When possible, I distribute solutions to homework problems, quizzes, and tests. To reduce students' anxiety about tests, I make old exams available on the Web, and often give practice tests. I usually give a test on prerequisites during the first week of the course. I do not consider memorization to be the most important in math courses; all my tests are open book/notes. Assignments and projects are naturally integrated into my courses. I spend time explaining the assignments and solving similar problems in class for further discussion.

My first interview for math teacher job.

I had my first interview for a math teacher position. Besides common personal questions I was grilled on my lesson plans and how I will spend 75 minute lesson time minute by minute. My IT credentials where of help of course but lack of teaching experience showed, especially when some visual aid tools were discussed. In upcoming blog posts I’ll talk more about lesson plans.

What issues should a teacher think about before a job interview? I wish I had found this site before! Especially discussions on changing career from an engineer to a teacher.

Update
I lost it! I shoot myself in the foot, saying “math lessons might be boring at times". Never ever boring! You are entertainer/teacher! Not exactly stand up comedy but close! Each time you want to say boring simply say interesting (but not exiting!). You will do yourself great service by changing your vocabulary a bit.

ADHD rating scale

I found this post on assigned seat blog:" I was just given a form I'd never seen before. It's entitled "ADHD RATING SCALE IV - SCHOOL EDITION." I am to return it completed concerning a student in about an hour. There are 18 different statements concerning behavior and a scale of 0, 1, 2, and 3.
0 == "never or rarely" 1 == "sometimes" 2 == "often" 3 == "very often"

1. Fails to give close attention to details or makes careless mistakes in schoolwork.
2. Fidgets with hands or feet or squirms in seat
3. Has difficulty sustaining attentino in tasks or play activities.
4. Leaves seat in classroom or in other situations in which remaining seated is expected.
5. Does not seem to listen when spoken to directly
6. Runs about or climbs excessively in situations in which it is inappropriate
7. Does not follow through on instructions and fails to finish work.
8. Has difficulty playing or engaging in leisure activities quietly.
9. Has difficulty organizing tasks and activities.
10. Is "on the go" or acts as if "driven by a motor."
11. Avoids tasks (e.g. schoolwork, homework) that require sustained mental effort.
12. Talks excessively.
13. Loses things necessary for tasks or activities.
14. Blurts out answers before questions have been completed.
15. Is easily distracted.
16. Has difficulty awaiting turn.
17. Is forgetful in daily activities.
18. Interrupts or intrudes on others"

Good reminder that it's all about child... and teacher's "attention deficit hyperactivity disorder".

Two logicians

Two perfect logicians, Sam and Peter, are told that integers x and y have been chosen such that 1 < x < y and x+y < 100. Sam is given the value x+y and Peter is given the value xy. They then have the following conversation.

Peter: I cannot determine the two numbers.
Sam: I knew that.
Peter: Now I can determine them.
Sam: So can I.

Given that the above statements are true, what are the two numbers? (Computer assistance allowed.)

Importance of teamwork

In a cliche effort to illustrate the importance of teamwork-oriented problem solving, the Boss has chained Dilbert to Carol The Secretary via wire wrapped around their wrists, as shown in the following snapshot:

The goal is for Dilbert and Carol to unlink themselves from each other; considering what a horrible woman Carol is, Dilbert wouldn't have it any other way. The wire is unbreakable, and as much as Dilbert would like to saw off Carol's limbs, that's against company policy. How can Dilbert and Carol get away from each other?

First Days of School! Classroom Management! Discipline!

I'm really glad I found this website! Here are Common Mistakes!

* Don't Smile 'Till Christmas: Becoming an effective teacher does NOT equal being mean! Students want structure, want to be able to feel comfortable, safe and to know what is expected of them. Refusing to smile does not insure that students will behave or that they will want to learn.

* I Want to Be Their Friend: It is great that you love students and want to be close to them. You may be loving, caring, friendly and sensitive, but do not set a goal to be a friend. They need you to be an adult role model that they can admire and look up to. You are setting yourself up for disaster if this is how you approach your classroom.

* Start the First Day of School with an Activity: Most new teachers are so excited about content and having the students engaged in learning that they forget to spend time teaching students the rules and procedures. The first week of school, elementary or secondary, should be spent getting students accustomed to your expectations for the classroom. Teach them the rules and policies, practice them and review them. You can not spend too much time on this. You will not regret the "lost time."

Sandwich falls by oil downward at the worst posible time.

The team of a mathematician, a psychologist and an economist put into mathematical terms what we all knew:
that things don't just go wrong, they do so at the most annoying moment. The formula,
((U+C+I) x (10-S))/20 x A x1/(1-sin(F/10)),
indicates that to beat Murphy's Law you need to change one of the parameter:
U for urgency,
C for complexity,
I for importance,
S for skill,
F for frequency and
A for aggravation, default value 0.7
In the researchers' own words:
"If you haven't got the skill to do something important, leave it alone.
If something is urgent or complex, find a simple way to do it.
If something going wrong will particularly aggravate you, make certain you know how to do it."
Here is how to use formula:
The equation has seven steps to forecasting a potential Murphy's Law moment, so you can work out which factors you need to change to avoid it:
1. Rate the urgency, importance and complexity on a scale of one to nine and add the three figures together.
2. Rate from one to nine how skilled you are at the task, then subtract this from 10.
3. Multiply answers to 1 and 2 and divide by 20.
4. Rate from one to nine how frequently you perform the task and divide this by 10.
5. Rate the sine (or sin) of your answer to step 4 and subtract this from 1.
6. Divide 1 by your answer to step 5.
7. Multiply your answer to step 3 by 0.7 and multiply this by your answer to step 6, and that's your Murphy’s Law rating.
The closer to 10 it is, the higher your risk of falling victim.
