Programming in schools is no longer a novel subject. It is now quite commonly found in our schools either in formal or informal curriculum. Programmers use creative learning tactics to solve problems and communicate ideas. Learning to program is generally considered challenging. Developing and implementing new methodologies in teaching programming is imperative to overcome the current challenges associated with teaching and learning of programming. This case study aims to contribute to the programming education in schools by investigating how students learn in an online programming while involved in peer review of codes. The study subsequently examines students' perceptions of the pedagogical, social and technical design of the online programming learning environment. When students are involved in providing and receiving feedback and creating their own identity in a programming community, they may be better prepared for learning and applying programming in their undergraduate studies and their future career in the field.
