WebcamMax FTW...

2009-11-19T15:17:00.004-06:00

As a high school mathematics teacher with 11 years of experience, I have heard every excuse in the world from students about their inability to meet the expectations of the course. Believe it or not, often my class is not at the top of their priority list.

I also realize that my subject can be a large source of frustration for my students, as they desire to do well in the course, but for whatever reason, they are unsuccessful and simply cannot solve the problems. It doesn’t help that we only have 45 minutes per class period in most cases, and I often have classes of 25 or more, which provides me with less than 2 minutes per student on average to work one-on-one with any particular student. Clearly, an extension of the classroom is needed to better serve students.

I have been interested in screencasting and the use of online video for over a year now, and I’ve been looking for tools to be able to hold live review sessions on the web for my students. Last night I started using WebcamMax to help set up a UStream.TV show that I am planning to use to hold online review sessions with my high school math students, and tested it a bit today while at the Illinois Education and Technology Conference (IETC or Il-EdTech). I must say I'm very pleased with the results and I hope students take advantage of this exciting technology.

You can see the result of my most recent test below:

For this project I used WebcamMax to feed into UStream, and OneNote as my platform to demonstrate the mathematics, and I found setup to be extremely easy. When I installed WebcamMax, I was prompted by the program to set up WebcamMax for the most common web apps that would use a webcam; one of which was Ustream. It all worked quickly and flawlessly.

The next item was to set up WebcamMax to show my screen, rather than an actual web cam. Again, the settings were very straight forward:

One of the things I was concerned about was how much of a hog the program would be on my system, given that I am using a relatively slow performing Tablet PC. I was pleasantly surprised that my system continued to perform well, even with UStream, OneNote, and WebcamMax all running concurrently.

I also was worried that there would be a significant delay between the time I wrote pen strokes on the computer, and when it was received by my clients watching the show. In testing it with my colleagues the delay was only a couple of seconds, which is perfectly reasonable. There was also no tablet pen lag while using OneNote, even though I had the other two apps running at the same time.

I highly recommend WebcamMax for use with solutions to problems such as mine, and as a general all-purpose piece of software for your webcam. You can download a free trial of the software at http://www.webcammax.com.

Intro to Algebra

Chapter 7 Test. No new HW.

Computer Science 2

Underclassmen - Work on the Sporacle project we talked about in class yesterday.

Seniors - Exam review day and questions.

Now that that's out of the way....

Precalc - Summaries and info regarding next week -

Seniors - Today was your day to ask questions in class regarding the final exam. Make sure you report to the Library Classroom both Monday and Tuesday of next week to take your exam. If you have any last minute questions, I will try to arrive at school at around 7am to answer them.

I anticipate having your grades done sometime on Wednesday. I don't know if they will be ready by the time I see you, so if they are not ready by then, just send me an email later that day or Thursday.

Juniors - Work on the 9.1 Review Sheet given in class. I will try to post a link to this later today.

Regarding the schedule for next week, I'm going to change things around a bit...I think I have a solution that works best for everyone.

Monday and Tuesday - We're going to to push hard and finish both 9.2 and 9.3 on these days. These are by far going to be the toughest in-class days for the Juniors left in the year, so please come prepared. You may want to read up on these two sections to make the two days easier.

Wednesday is going to be the senior send-off and the first day of exam review for Juniors.

Thursday will be another exam review day.

Friday I will be out of the building...so on THIS day we will have a QUIZ on sections 9.1-9.3. I will have to make comments regarding this quiz online once it is graded, since we will not be able to go over it in class.

Then next week will be the final exam.

I appreciate everyone's flexibility regarding these days...I know I'm not making it easier by being out on that Friday, but I'm working around it as best I can.

On a side note...I'm taking a quick look at the projects and they really look nice. I hope the quality of the mathematics matches the asthetics. :)

If I haven't said it enough - I really appreciate your hard work this year. I know that the course (and I) have been difficult at times...but mark my words it will pay off.

Take care.

Work on exercise 2. If you manage to finish early, here's a bonus opportunity that I will also make due Monday at 2:30pm (due to the nature of this assignment being a bonus, it will be much more open ended than the other assignments):

Design a RolePlayingCharacter class. The RolePlayingCharacter class should have variables that control the amount of damage the character does, the amount of armor(defense) the character has, how much health they have, and any other relevant info about the character. It should also have "get" methods for displaying their health, and other needed info.

To test your class, I've created a main method that instantiates an object of type RolePlayingClass, and uses methods that I feel you should have. You may modify my main in any way that you'd like.

To get credit, you simply need to show me your code in class and run the main that I provide for you to verify that it works.

(Side note - do you notice a connection between the number that is entered and the answer?)

2. Recall the program that you wrote that searches a sentence for a particular char. Rewrite this program so that it utilizes a for loop.

Intro to Algebra

We started Chapter 6 today - section 6.1 - Solving one-step inequalities.

I also gave a new schedule and assigned homework #1.

Computer Science 2

In order to warm everyone back up to computer programming, I gave two problems. You need to demonstrate that each of these runs correctly for credit on this assignment:

1. Write a program that prints out a list of perfect squares up to (and including) the integer value specified by the user. For example, if the user enters in 100, the output of the program should be:

1 4 9 16 25 36 49 64 81 100

Print an error message to the user if they enter in a negative number.

2. Write a program that will count the number of instances in a given sentence of a specified char by the user. For instance:

The user enters in a sentence: “I love Computer Science.”

Then specifies a char: o

The program then returns something to the effect of: “There are 2 ‘o’s in your sentence.”

a) Outputs a new sentence that replaces all 'a' characters with 'z' characters.

b) Outputs a new String that only shows the first 7 characters of the original sentence (so, make sure when you prompt the user for a sentence, that they enter in at least 7 characters, otherwise the method you use to make this work will produce an error).

c) Outputs a new String that is the same as the original, but all UPPERCASE.

2) Modify your "Mad Libs" program to do the same three tasks as above.

Homework #7 for tomorrow (Again, see yesterday's entry).

Intro to Algebra

Complete the Chapter 3 Test B worksheets for homework. If you received a MATH-O card, fill in 16 answers for a chance at a bonus tomorrow.

Computer Science

For class today, complete the following:

1. Go here: http://chortle.ccsu.edu/java5/Notes/chap59/ch59_1.html and follow the online lesson all the way until the end of Chapter 59. (note that there are many other lessons like this one here: http://chortle.ccsu.edu/java5/index.html#59).
2. At the end, grab the code they show, put in into JCreator, compile and run it, and toy around with it to convince yourself you know what each part does.
3. Download this program: PushCounter. Please note that this is a .zip file that contains two .java files. You need to download both, save them to the same directory and compile them both.
4. Again, study this program, tinker around with it and convince yourself that you understand what does what.
5. Using the ideas in these two programs, write a small java application that creates a window with a frame and a button in it, so that every time the user pushes the button, something fun happens...be creative and be ready to demonstrate this in class tomorrow (Wednesday).
