About Mr. Wachs

Welcome to my website/blog. My name is Lawrence Wachs and I am a high school teacher in Winnipeg, Manitoba, Canada at Sturgeon Heights Collegiate.

Sturgeon Heights Collegiate

This site is designed for my students and their parents as a launching pad to get at any information needed for my courses, or as a place to give feedback on those courses.  I have been teaching since the late 90’s in the St. James School Division (where I also attended public school myself). I have always taught a variety of different courses and levels over the years including:

  • Computer Science 20S (grade 10)
  • Computer Science 30S (grade 11)
  • Computer Science 40S (grade 12)
  • Computer Science 32SIB (higher level grade 11 I.B.)
  • Computer Science 42SIB (higher level grade 12 I.B.)
  • Theory of Knowledge 32SIB (I.B. grade 11)
  • Theory of Knowledge 42SIB (I.B. grade 12)
  • Mathematics 10F (grade 9)
  • Mathematics Numeracy (grade 9)
  • Alternative education (at risk programming)
  • Social Studies 10F (grade 9)
  • Peace and Conflict in the 20th Century (grade 9)
  • Information Technology 10G (grade 9)
  • Information Technology 20G (grade 10)
  • Information Technology 30G (grade 11)
  • Visual Arts (grade 9)

My own education includes a Bachelor of Science degree in Computer Science (major) and Mathematics (minor), a Bachelor of Arts degree in History (major) and Sociology (minor), and a Bachelor of Education. Also I obtained certificates in Web page design, I.B. training, as well as work with special needs. Before teaching I worked as an artist, with special needs children, and as a computer technician. On a personal level I live in St. James with my wife and two children.

  1. Mr. Wach
    My name is Chris Hancock. I am a Computer Science and Engineering teacher at Columbia High School in Huntsville, AL. We are IB School of about 700 students. I came across your site and was excited. I just recently was given the IB TOK course. I throughly like what you have done with the website. I wanted to know with you permission if I could use some of your material to help me with my current course of TOK.

      • Hi Sharon, nice to hear from someone close by! Feel free to use anything and modify anything you find useful. I have lectures (PowerPoints), lessons (PDFs), assignments, and videos off my TOK pages and the accompanying Google Drive and Youtube page. You can also email me if you need the original Word files or anything else you need. Good luck and let me know what I can do to help!

  2. Hello Mr. Wachs! First of all, I would like to thank you for sharing your resources about Computer Science. I will be teaching IB CS this coming school year and I am using your site as a starting point on how to go about things this year. Again, thank you very much! I do have some questions though. Is it okay if I just email it to you? Thank you very much!

  3. Hi Mr. Wachs, I too am about to begin teaching the IB Computer Science course for the first time and I would also like to thank you for sharing your resources. Thank you, Kind Regards Ted

  4. Hello Mr. Wachs,

    A colleague told me about how you are supporting teachers new to the fields of computer science, and I was wondering if you would give me some guidance for my students. I teach at Red River College and I have very little experience with languages. I did attempt some baby steps into coding using MS visual studio and C#. Is it possible for me to make a visit to your school at your convenience? I teach into the Business and Technology Teacher Education program, and I did see the announcement by the Government regarding getting funding to bring coding into the classroom. I would love the opportunity to speak with you regarding developing my courses.

  5. Hello Mr. Wachs.. My name is Jake Staffel and I teach at MB Lamar High School in Houston Texas. This will be my first year teaching the IB SL and HL curriculum and was relieved when I found your site as I there is not really too much for teachers new to the subject on the OCC in the TSM. I was wondering if you would mind if I borrow (heavily) from your curriculum for my first year instructing the course… I do have some ideas based off watching Tube Videos but in essence, I am starting from scratch. Thank you in advance for your consideration…

    • Hi Jake, feel free to use anything and modify anything you find useful. I have lectures (PowerPoints), lessons (PDFs), assignments, and videos you can find at the corresponding Google Drive and Youtube pages. You can also email me if you need the original editable files or anything else you need. I also have some tests, etc. that are not on those drives if you are interested. You can look at my various course outlines for timetable ideas on how I planned a timetable of delivery. Good luck and let me know what I can do to help!

  6. Hello Mr Wachs,
    I am new to teaching Computer Science from London UK. Thank you for the excellent resources you are sharing with everyone.

    • Hi there, nice to here from you and no problem what so ever. Any feedback you have would be appreciated. I love the Computer Science teaching community and we all support each other so well. Let me know if you need anything else or can’t find what your looking for.

  7. Hi Mr. Wachs, I teach IB Computer Science and I find your materials very helpful and one of the best out there. I currently use it for teaching my IB students, but taught I could add one or two things and also some of my students will like to make while reading, but the password is needed. Could you kindly assist me with the password if possible, I will appreciate! Thank you

  8. Hello Mr. Wachs,
    I happened to watch your ToK videos on Arts on youtube. And it was very useful while conducting my ToK classes. Thanks for it!
    Are you going to cover the others AoKs such as, Maths, IKS, RKS? I am eagerly waiting for these AoKs.

    • Thanks for watching. I do have a lot more TOK videos and am hoping to make more soon (or update some of them). You can find all my videos on my main YouTube page (https://goo.gl/mFQh75), or specific TOK videos for my grade 11 course (https://goo.gl/xHzwNg) and the videos for my grade 12 TOK course (https://goo.gl/fLsGcV). Please give me any feedback and keep in mind I recorded these live during a TOK lesson one day (they are not rehearsed).

      • Thanks Mr. Wachs for sharing the resources.
        I have gone through these resources. G11 and G12 look similar.
        Please upload more videos on other AoKs. It’s really very useful.
        For current G11 batch we have finished Natural and Human Sciences. Now we are taking up Arts and then by mid Feb we will be taking up History and then the mock presentation. For the next year we will be taking up the remaining AoKs. Earlier we used to teach only 6 AoKs to the students except IKS and RKS. But this year onwards we are planning to teach the remaining too, as these might be useful for their essay writing.
        Once again thanks for sharing the resources 🙂
