'15-'16 Encoding Text

Use this as a space to record your feedback and questions about this lesson.

Another great lesson that needs little else beyond the supplied materials.I naturally flows from the previous lessons and into the next section on ASCII. I don’t think I would change a thing. I cant wait to see what the students come up with.

It’s great that these lessons pull together what students have learned in the prior lessons.

Other than following the lesson plan. I’m considering having the class develop an agreed upon protocol that will be used by myself and students to communicate with. For instance, I will have a message on the over-head projector when students come into class and have them decode it. May also have them create messages with the protocol and send to each other.


The lessons are a continuation of how to encode messages, in this case text messages and ASCII code. I will follow the lessons outline, use the resources provided, and the rubric provided for assessment.

Other than the activities already incorporated into the lesson, I think I will use a warm up binary puzzle for students to decipher and get their brains thinking about binary and how it all works

These lessons are so well laid out. I can’t wait incorporate them in my classroom.

I am feeling like need of a quiz. I don’t think I will survive without once a week quiz or test. I love the lesson, but I will be behind pacing at this point.

I love David’s idea of having a class protocol! Great way to start class with a secret message!

I like the idea that groups take their protocols to other groups to try out. This may give students insight as to how clear their protocol actually is. Their group might think it’s crystal clear but another group may have a hard time following the protocol.

I like the idea of developing a text encoding method, I am sure the students will have several ideas to incorporate their own encoding methods.Like jdozal said, I think the idea of testing each other’s protocol will help the students find the deficiencies of the system designed and improve the features. The lesson plans are well written and I can’t wait to see the ideas generated in the class.

I’d like to follow closely the lesson plan. I like the rigor in this lesson and the cross with what they are doing in math. This should be a strong support for how students problem solve in this class but especially in Algebra.

Again students are looking for rules/patterns/ protocols. I am excited about teaching all of these lessons. I worry about my delivery of the necessary questions. The first time around, I will try and teach all of the lessons as they are. I will allow students the majority of the time working with their partners developing the protocol and using the internet tool. From my experience, this is where the excitement and learning occur.

I kind of feel like most students will automatically default to a 1 A, 2 B, etc. table, with perhaps a few exceptions in between. Maybe that’s all we should be expecting. If we are supposed to expect more, however, it would be helpful to see other examples of “model” work. I’m all for the “openendedness” of this lesson, but not having the experience of having taught this lesson before, I find myself challenged imagining what the possibilities might be. Having something more to reference (aside from other standardized character sets) would be helpful.

When I began the online PD I was not actually preparing lessons like I am now. I find that I am using presentation software to organize much of the lessons. This helps me with timing and knowing where I am with unfamiliar material. I imagine as I teach the curriculum over the years I won’t need it as much.

I look forward to seeing the protocol that isn’t 01-26 …

and the explanation for why those student(s) chose to go in a different direction. This discussion may be a useful reference point for security and cyphers.

I’d like to convince them that they should always ask someone outside their own group to test their protocols. I’d start out by requiring it early in Unit 1, then see if I can get them to the point where they automatically ask someone do it.

This is a great lesson. After the groups have presented their protocols, I think it would be fun to implement David’s idea of developing a class protocol as a way to wrap up the ideas. Perhaps then the students could decode a message at the beginning of the next class for a starter.

I like this lesson. I would use the simulator of course.
I am thinking of a challenge. Something to do with either giving the students other students protocol with two letters given and they should have to figure out the protocol. I could also make one up and distribute it to the entire class.

I like the lesson! Simulator is great of course! I want to also find a way to have them find not only a good protocol, but one that not only is accurate…but can use the least amount of “digits” …maybe talk about efficiency and accuracy in encoding to end the lesson!
