How do you read Blogs? Shrook?

17 04 2007

We have all heard about blogs. Some of us blog. Some of us think it’s taboo to blog. I recently did a poll of 8 teachers I was working with and 1 out of 8 blogged. Not bad! But generally, I get the feeling everyone reads a blog by web surfing into that page. You don’t really know whether there is an update on that page, you probably have it as a bookmark and when you have really nothing to do or just to take your eyes off marking assignments, you click and see if there is an update. As I am blogging now, my wife has just informed me that our family blog is now going to hit the 600th post! Amazing! And we actually have an active audience reading and I find this most conducive for a learning classroom.

So things to find out:
1. Do you know that you can search in Google under BLOGS and you might just find your name there on someone’s blog? :)
2. Do you know that there are different blog web systems? Most people are used to Blogger. I am using a different one called WordPress.

I will talk about blogging one of these days with text, video, mobile blogging, etc but for now, it’s HOW you read them. Boils down to something called RSS. You might have seen it. We make use of that and in different applications (called RSS Readers), it will display all the blogs you want to see and whenever there is ANYONE who posts something new, it turns up automatically and it indicates it (as if there is a new email that has arrived!) That is so convenient, like when you are a teacher and trying to read a student’s blog. I know a teacher who has her students do reflections in a blog and she has to read them one by one and she can never tell if the page is updated. Here’s a RSS Reader to the rescue! SHROOK.

It is a free reader and I like this one as it is simple and quick to use. In the case of the teacher, she found her kids doing so much more than pen and paper and she can see in her SHROOK if there is a new posting and she can group it in the application as each class. Brilliant!

Collaboration with SubEthaEdit

16 04 2007

Before I start on Google Apps and Docs in a new post, let me first talk about SubEthaEdit. This version that we have started using is version 4 and it is free for non-commercial use. It is a really useful application since it allows everyone to to fire it up as a document and you can type away, even in Chinese (unicode). Using Bonjour (a form of network within a local area), the document can then be shared with another person with a computer and the typing turns up real time on everyone’s computer.

What is amazing for this application is the ability for a central person to take control (aka teacher) and then share out this as a document to groups of students and you can decide whether a person gets a chance to just read it or to type and together as a team, students are able to collaborate on a research/study topic.

I find this very useful when we are going to work on proposals and project reports. I start off with chapter headers in a document and I then share it out. Different team mates have charge over a single chapter and we then review the sections together.

Do note that this is however a software that is for the more mature student as the younger ones tend to like to select everything and press delete and of course everything is whipped out from everyone’s computer!

Mac OS Grapher

16 04 2007

Some of us have used this before in the older operating systems before OSX came about. When I started exploring Grapher in OSX, I started clicking around and found this to be a really awesome software. Having it in the Utilities means it is usually ignored and 4 out of 5 Math teachers I have spoken to who use a Mac do not know about this!

This is a great software both teachers and students can use. I’ve started using it to chart out equations very quickly and be able to have that into documents.

As I started exploring with another teacher, we started trying to draw a graph and we were then able to differentiate the curve, find the tangent, root, local extremum and inflection point. For students who had basic understanding of drawing curves already, this was a way to draw up a family of curves, find the intersections and also be able to animate the whole learning! I found that most exciting for a teacher who was keen to do simple learning objects that were animated and could be placed in LMS for students to learn.

I am trying to create a manual for users to use Grapher. If you are keen, email me at maceducation@mac.com!





P*mp Your Calculator!

3 04 2007

At first glance, the built-in Calculator in Mac OS X is simple to use, but devoid of calculus and other functions. There is a very obvious but usually unknown way to enhance your Calculator:

There are many options available, including RPN (Reverse Polish Notation, I believe… :-) ), Programmer mode, etc

BBC Motion Gallery

2 04 2007

Need a place to find high quality video? One of our latest eureka’s is BBC’s Motion Gallery widget for Mac OS X Tiger and above. A comprehensive, if not legendary, historic record with over 700000 hours of content. Caveat: Do check with the website to see if the clips you need are royalty-free (many are). YMMV.

Electronics: QUCS and Solve Elec

2 04 2007

I have been demonstrating QUCS (Quite Universal Circuit Simulator) for quite a while now and it’s a really awesome software that is easy to use and being able to create a circuit simulation in class without having to really set up bread boards, wires etc is really cool.

But several teachers have complained that it is rather difficult to install as it requires Qt (and this is NOT quicktime). The download site can be found here.

A new kid is on the block called Solve Elec.

This is a simple installation and I found it easy to use with a new GUI and does circuit analysis and resolution. Some of the main features includes:
- circuit drawing
- computation of litteral formulas in the circuit
- verification of equations related to the circuit
- graph drawing
- definition of quantities by their formula
- editing, saving and printing reports made of various components
- integrated help.

English-Chinese Dragon Dictionary

30 03 2007

When we were in Philippines, some Chinese teachers asked if there was one that was available on the Mac and if possible free – Dragon Dictionary

We finally found one, pretty decent in terms of the number of words provided and also having the ability to provide hanyupinyin. You even had an option for simplified Chinese and that was useful. The “start speaking” option would have been most useful IF it was able to pronounce Chinese but does not. It only says out the meanings for the English word you would have typed in.

YEP: the iPhoto for PDFs

28 03 2007

I had reviewed this many months back when it was out in the first draft versions (which meant it being free).

I thought it was great since I had so many PDF files all over the computer in my partitioned harddisks. Somehow, I lost the software along the way and when I wanted to use it again, the website showed an updated version that was no longer free!

Jr had thankfully pointed out that he had it and also insisted that it was on the website if you scroll right to the bottom. I tried…. but I found it again on versiontracker (hooray!) and here it is again for everyone. It’s very useful when you can tag your PDFs and then also be able to present them very quickly. I noticed especially in universities that this is useful. In the 1to1 classrooms, I am only about now trying to introduce this.

Have you found it useful in your own way? Let us know!

Download it here (scroll and look for version 1.1.2 which is freeware)

Mac Shortcuts

27 03 2007

I keep getting asked for notes on shortcuts whenever I do Mac OS Beginner Courses. I keep saying, great way to make use of that lazy arm by your side and rather than reach out to use the mouse, why not use simple shortcuts? I actually challenged someone a couple of years back and it was quite amusing to see the person using the mouse when a neutral party gave the task to do (like copy, cut, create new folder, duplicate, save, quit, move the window behind the active window you are using, etc) So anyway, click here for all the shortcuts you can use.

If you need to change some of them on your Mac, click SYSTEM PREFERENCES > KEYBOARD & MOUSE > KEYBOARD SHORTCUTS. Have fun!





Cn3D for Biology

27 03 2007

For a while there in 2003/2004, we did quite a bit in Bioinformatics and one such event was the Biohackathon that was held with 40 top scientists from around the world. Some of those involved came from very distinguished institutes such as the Whitehead Institute where Jr and Ad had a chance to visit.

While doing sessions with secondary school students on Bioinformatics, one simple software was Cn3D. This is a helper application for your computer that allows you to view 3-dimensional structures.

The structure for the DNA (Double Helix)

You can download structures here from NCBI’s (National Center for Biotechnology Institute) website. This is a database website maintained by the NCBI and there are other databases you may be able to search. These are PRT file formats that can be used to show the structures. Cn3D simultaneously displays structure, sequence, and alignment, and now has powerful annotation and alignment editing features.

Students would use this to visualise the structures on each of the computers and teachers could explain the structures. You may be able to rotate the images and as a 3D representation gives a more realistic feel to how a virus is like, etc. Some teachers were providing classes with a series of structures where students had to identify them, analyse them with a given set of questions to answer.

The website has an excellent tutorial as well.
