As an instructor of computer science at Simon Fraser University, one of my roles involves assessing the level of computer science knowledge possessed by high school graduates and the ease of their transition into higher education. These assessments help the school to evaluate the adequacy of our university’s introductory computer science courses. Unfortunately, we have observed that a considerable number of students are struggling with our first-year programming courses.
In this article, I will explore the recommendations made by the British Columbia government regarding the computer science field in grade schools. Specifically, I will investigate how these recommendations are being implemented in schools across the Lower Mainland and evaluate whether they are effective in preparing students for university-level computer science coursework. By doing this, I hope to shed light on the current state of computer science education in our region and make recommendations for improving the preparation of students for university-level computer science coursework.
Computer Science Curriculum Recommendations in K-12 Schools
There are two ways to incorporate CS concepts into a grade’s curriculum: as an entire course or as an integration of existing materials. A common misconception about computer science is that it has a bi-conditional relationship with coding, that they are one and the same. In fact, a well-designed curriculum must also include critical thinking, problem-solving, teamwork, communication skills, technical writing skills, and testing methodologies, among other vital skills. Successful implementation of a computer science curriculum not only contains coding but also equips students with other diverse tools for their future careers.
The BC government website (https://curriculum.gov.bc.ca/curriculum/adst) recommends that students from kindergarten to grade 3 are introduced to computer science basics, such as algorithms, sequencing, and problem-solving concepts, through interactive, “non-computer” activities. In grades 4-5, students move on to learn about block-based programming, granting them an entry into coding and the ability to create interactive digital media. In grades 6-7, students now apply their computational thinking skills to solve real-world problems using charts, lists, diagrams, and arrays with an introduction to computer architecture and hardware, responsible computer use, and visual programming. Finally, in grades 8-9, students learn about basic software instructions with algorithms that others can repeat, debugging algorithms, elementary modularization, binary data representation and programming languages, including visual programming.
In Grade 10, students will delve into topics such as security risks, debugging, networking, social implications, digital literacy and citizenship, and planning and writing simple programs (including games). In a separate course, it is recommended that students explore Computer Applications that center on understanding the importance of user experience. computer hardware, peripherals, internal and external components, standards, intermediate features of business applications, including word processing, spreadsheets, and presentations, operating system shortcuts and command line operations.
In addition, the B.C. government recommends a Web Development 10-course covering design opportunities, HTML and CSS, domain and hosting, copyright laws and Creative Commons usage protocols, ethics of cultural appropriation, security and privacy, and database management. While some of these areas may appear outdated, they still offer a solid understanding of web standards and communications.
In grades 11-12, students can enroll in Computer Programming 11 and 12, where they will learn various programming skills. These skills include the design cycle, error handling, debugging, problem decomposition, reading and altering code, pair programming, programming constructs such as input/output, conditions, and loops, algorithm design, functions, classes, pre-built libraries and their documentation, inline commenting to document source code, use of test cases to detect logical or semantic errors and software ethics.
In general, the suggested curriculum appears to be quite ambitious, and I have concerns about the extent and practicality of the material taught in the classroom. Several of the topics covered are typically introduced in second-level programming courses at the university level. If the high school curriculum can provide a sufficient depth of understanding, it would establish a strong foundation for many students, enabling them to tackle more advanced computer science courses without difficulty.
CS Curriculum implementations
Code.org (https://studio.code.org/courses?view=teacher) is the leading resource for computer science education, offering an excellent and well-designed curriculum to introduce students to computer science at all grade levels.
For elementary school students (grades K-5), Code.org provides CS Fundamentals. This program includes “unplugged” non-computer activities to teach computational thinking, problem solving, programming concepts, and digital citizenship.
The middle school (grades 6-8) curriculum, known as Computer Science Discoveries, builds upon the elementary school program by introducing students to more advanced concepts at an intermediate level. These include web development, communication, and problem-solving.
For high school students (grades 9-12), Code.org offers more specialized courses in computer science for students who wish to dive deeper into the subject. These include physical computing, big data, privacy, and algorithms, and advanced placement (AP) courses in Java for more advanced students.
Code.org also offers professional development courses for educators to help them effectively teach computer science. The curriculum and courses provided by Code.org are designed to help students develop computational thinking and coding skills while broadening their understanding of computer science.
Out of the 37 public high schools in Burnaby, Surrey, and New Westminster, only 4 schools use code.org as a guide, and these schools are all associated with the Advanced Placement (AP) programs. These numbers suggest that schools are aware of the usefulness of code.org materials but need more staff to implement the courses. There needs to be a standardized curriculum across these schools.
For example, the Burnaby High School website describes Computer Science 10-12 as “an introductory programming course for students with no experience. Learn to create video games for your phone, tablet, computer, or the web.” This description is very vague and suggests that these courses do not come close to implementing the recommendations set out by the B.C. government. Other schools in Burnaby do not even offer Computer Science 11/12 courses. In contrast, New Westminster Secondary offers Computer Programming 11/12, which fully implements the government’s recommendations and more. These courses should be AP courses, depending on the depth of coverage. The difference in offerings between the two school districts is concerning for students entering higher education computer science studies as it may result in significant differences in programming knowledge.
I attempted to reach out to over 20 Computer Science teachers from different schools in the New Westminster and Burnaby areas, but unfortunately, I did not receive any responses from them. Unfortunately, there is a lack of motivation and interest in enhancing their teaching methods in CS courses. In a recent conversation with Shannon Thissen, the Regional Administrator of Educational Technology and Computer Science in Capital Region ESD 113, she confirmed that this is a common issue in all communities. She suggested that CS mentorship and coaching could alleviate teachers’ fears and uncertainties about teaching the subject.
The BC government’s and code.org’s recommendations for computer science education are ambitious but achievable. Higher education instructors and industry leaders should collaborate with high school teachers to strengthen and standardize the various tools and workflows currently taught in the CS curriculum.
In subsequent posts on this topic, I plan to explore various initiatives and reach out to more teachers throughout BC to gather more specific information on the curriculum and materials being taught in classrooms. Additionally, I aim to investigate the differences in implementing CS 10, 11, and 12 courses in schools across BC. It would also be interesting to compare the needs of schools in the lower mainland, which are primarily middle to upper-middle class, with those in interior communities. By doing so, we can determine if there is a significant discrepancy in the quality of computer science education and explore potential solutions to bridge the gap.

It is interesting to read about BC suggestions for computer science curriculum. I like how they have specific topics recommended for each grade levels. I wonder what kind of research findings they based their suggestions. Great blog!
I like your purpose in this model, and I think it is very important for K–12 students. To achieve your goal, it helps students obtain all knowledge about computer science before the university level. I agree with you to work with school teachers to ensure that students reach the university level ready for computer science. I look forward to seeing you achieve your goal!
Bobby, as a teacher of computer science, this was a fascinating look at an overview of how the topic is addressed at all levels of primary and secondary school. I really like the idea of providing mentorships or coaching. I’m excited to hear more about your future plans for this topic – sounds like you’re going to be doing some interesting stuff. Keep us updated!
