This thread has gone in some pretty weird directions over the years. I'm glad to see what ldjb wrote about it last year, as it confirmed that my thinking on TU100 was most likely correct.
I'll be starting on a BSc (Hons) Computing & IT degree with this module in October, and have just been scanning around to get a good feel for it. The comments about it being useless in a career seem to miss the point of the module. The main point of the module seems to be getting one used to the coursework requirements for this course and discipline. I frankly don't expect to learn much from the content of the module (though i hope I'm wrong), but am quite looking forward to feedback on my TMAs to help me learn what the tutors and assessors are looking for.
A secondary (though important) aim would be an introduction to many of the concepts that will be explored in advanced modules later in the course. While not necessarily useful or applicable to a career, it can give you a feel for how much you enjoy working with the concepts and help choose your course path.
With reference to Sense, even before Urist confirmed it, I had a suspicion that it was similar to Scratch or a dozen other drag-and-drop programming languages. My five-year-old son loves these. Again, the point is not to teach you a useful language, but one assumes to introduce you to the basic concepts of all languages, such as if-then-else flow, for loops, accepting input, etc. Useless for a lot of people in the course, but everybody has to start somewhere. My son giggles with glee when his nana can't make the elf walk to the gift on the Google Santa Tracker programming game, but the point of the OU is supposed to be accessibility. These tools are great because the building blocks of programming are literally represented as visible and movable blocks.
I've been working in the industry for about 20 years, and have no real need for the degree other than as an example to my children. That said, it's of great personal importance to me, and something I've always wanted. I dropped out of US high school two years before graduation, had to study for an equivalency exam via distance learning, and was always too busy with work for traditional distance degree courses.
Technology finally made distance learning less of a struggle than it was when I got my equivalency diploma. I've been enrolled twice with different universities only to be forced to quit almost immediately. Once was to move to the UK ahead of Theresa Mays' immigration policies, once was the birth of my second son. I'm hoping this time it will stick.
My current plan is to go through the networking path, with the web development module as an optional. I'm also taking MU123 maths, because I just want it to be easy. It's hard to translate my US studies to UK terms, but I'd say my maths are well above GCSE level, but so-so compared to A level maths. I took the MT124 eval. I got everything right though half of it, but it took me forever to remember rules I hadn't used in 25 years. When it started to ask me to solve polynomial exponential fractions, I just stopped trying. Who has time for that? Especially when i can state categorically I'll never need it for either the degree or the field.
I'm glad to see there are a few others on the course staying in October here. It's always nice to share the pain.
