The Importance of Problem-Based Learning in the New Coding and Robotics Curriculum
The newly released Coding and Robotics curriculum has a drastically different feel compared to most other South African curriculum documents I have encountered so far.
Most noticeable is the shift from a content curriculum to a competency curriculum, and the introduction of many educational concepts which were less mainstream when the CAPS (Curriculum Assessment and Policy Statement) was first conceptualised. The focus of the new C&R curriculum is not only to equip students with knowledge and skills in terms of coding, but also foster a mindset that emphasizes problem-solving, creativity, and innovation. This approach was emphasised by Ashric Don , contributor to the final version of the C&R curriculum, on a recent podcast with Resolute Education. A core component of delivering the C&R is Problem-Based Learning (PBL), an approach that transforms traditional learning paradigms by centering on real-world challenges and student-driven inquiry.
Understanding Coding and Robotics
Coding, in essence, is the craft of creating a logical set of instructions that both humans and computing devices can understand and execute. This requires a profound grasp of computational thinking and problem-solving abilities. Through coding, students learn to break down complex problems into manageable steps, design algorithms, and develop solutions that are both efficient and effective.
Robotics, on the other hand, deals with the design, operation, and utilization of robots that can perform tasks autonomously, semi-autonomously, or under direct control. These robots are designed to perform specific tasks or solve problems. Robotics provides learners with a tangible application of their coding skills, enabling them to see their logic and design come to life. This hands-on experience is invaluable as it bridges the gap between theoretical knowledge and practical application.
The Power of Problem-Based Learning (PBL)
PBL is a dynamic and learner-centered approach to education that engages students in real-world problems and encourages active inquiry. Unlike traditional rote learning, PBL focuses on developing critical thinking, problem-solving, and collaboration skills. It encourages learners to ask questions, seek answers, and apply their knowledge in practical situations. In the context of C&R, a problem-based approach also provides a vehicle for guiding learners through the design process, and purposefully apply the different components of Computational Thinking. To do this effectively, the emphasis should be on the learning process rather than the final product. The journey of solving a problem—identifying the issue, brainstorming solutions, testing hypotheses, and iterating designs—is where the most valuable learning occurs. This approach ensures that students develop a deep understanding of the concepts and skills they are learning, rather than just aiming for a correct answer or the perfect product.
The NCS (National Curriculum Statement) aims to produce learners who are able to:
Until now, the implementation of a content-based CAPS did not actively address these aims. While pockets of excellence exist where learners engage with 21st-century skills and develop their problem-solving abilities, the majority of South African learners are pushed through a cycle of teach-to-the-test, learn-for-assessment, deliver content-based artifacts with limited skills application, and forget what you have learnt by the start of the next term. My hope is that Coding and Robotics, provided it is implemented successfully, will be the catalyst for curriculum reform which sees a system-wide move from content to competencies, especially up to Grade 9 level.

Assessing Learning in Coding and Robotics
Assessment in Coding and Robotics is envisioned to go beyond traditional exams and tests. It involves observing learners in action, watching how they approach and solve problems. By focusing on the process and competencies, educators can gain a comprehensive understanding of a student's abilities and progress. The Foundation Phase CAPS document provides examples of rubrics that can be used for this purpose.
It remains to be seen what assessment methods are prescribed by the Intermediate and Senior Phase documents, but it would be counterproductive to apply a content-based assessment to a competency-based curriculum. Changing the educators' mindset around assessment is crucial to the success of C&R. This is especially true in Grade 8 & 9 where it is often FET educators who teach down to GET level, instead of GET specialists. Unfortunately the same approach to prepare Grade 11 and 12 learners for the content-based NSC Exams would no longer be applicable to Grade 8 & 9 learners following a competency curriculum.
Fortunately there are other countries that have walked the competency and PBL journey for many years, and we can definitely learn from the existing research. Academic research has been done, books written, frameworks developed and many articles published on internet platforms.
Conclusion
The incorporation of Problem-Based Learning in the new Coding and Robotics curriculum is a significant step towards preparing students for the future. By focusing on real-world problems, fostering critical and creative thinking, and emphasizing the learning process, PBL ensures that students are not only equipped with technical skills but also possess the ability to adapt and thrive in an ever-changing technological landscape. Together with exploring Coding and Robotics, teacher-training should focus on the effective implementation, management, and evaluation of a Problem-Based Learning approach.

Ill start: At a lot of high schools, where Grade 8&9 Coding and Robotics will be a requirement, there are mostly FET focused teachers, who teach down to GET. The mindset required for teaching FET, especially with NSC exams in mind, is often also applied to GET students. PBL requires a drastically different approach. It's not impossible, but teachers are going to have to make a very conscious mindset change.
