Program Overview
ICS3U (Introduction to Computer Science, Grade 11, University Preparation) and ICS4U (Computer Science, Grade 12, University Preparation) are Ontario's university-preparation computer science courses, described in the ministry's Computer Studies curriculum for Grades 10 to 12 (2008). The ministry describes ICS3U this way: "Students will design software independently and as part of a team, using industry-standard programming tools and applying the software development life-cycle model". For ICS4U it says: "Students will use modular design principles to create complex and fully documented programs, according to industry standards". In each Grade 11 and 12 course, the curriculum document says, the first strand is Programming Concepts and Skills and the second is Software Development, and the fourth strand "deals with the role of computers in society". ICS3U has no prerequisite; ICS4U requires "Introduction to Computer Science, Grade 11, University Preparation", which is ICS3U.
This course runs alongside the student's own ICS3U or ICS4U class. We teach in whichever language the school uses, Python or Java, and we follow the order of the student's school course outline, so what is learned here is used in class the same week. Every topic starts with the problem before the syntax: reading the task, breaking it into steps, writing the algorithm in plain words, then turning it into code and testing it. From there we build data types, control structures, lists and arrays, modular programming with functions or methods, string and file handling, sorting and searching, and for ICS4U students, recursion and object-oriented design. Assignments and the final project or exam are the student's own work: we explain, question and review, and the student writes the code.
Please read this plainly: Modern Age Coders teaches alongside school and does not grant Ontario high school credits. ICS3U and ICS4U are each worth one credit, and families who need the credit take the course through their school or a ministry-inspected credit provider. What we add is understanding, practice and confidence, in live classes with a real teacher.
What Makes This Program Different
- Built around Ontario's ICS3U and ICS4U, following the student's own school course outline week by week
- Python or Java, whichever the school uses, with the same concepts shown side by side when a student meets both
- Problem solving and algorithm design before syntax: plain-word steps, tracing tables and test cases come first
- Honest about credits: we teach alongside school and do not grant Ontario high school credits
- Assignments stay the student's own work: we explain and review, we never write school code for them
- Exam review technique taught directly: tracing code by hand, writing code on paper and planning answers under time
