Professional Foundations

I open my portfolio with the professional foundations of my teaching: my context, my background, my teaching values, and the evidence that introduces the later chapters.

Chapter purpose

Why I start with Professional Foundations

I have chosen to begin with Professional Foundations because I want the reader to understand who I am as a teacher before looking at the more detailed evidence in later chapters. This chapter is needed to introduce to my background and to explain the teaching context, values and professional experiences that shape my classroom practice.

The evidence here is deliberately contextual. It gives the reader the foundation for understanding the later chapters on planning, teaching, adaptive practice, reflection, observation and evidence of student learning.

Professional Profile

A short professional profile based on my teaching CV.

Professional profile extract

I am a qualified Computer Science teacher with experience teaching IGCSE Computer Science, AP Computer Science Principles and AS/A Level Computer Science in an international bilingual school context. My teaching aims to make abstract computing concepts accessible through structured explanation, step-by-step modelling, practical programming, project-based learning and real-world applications.

Before becoming a teacher, I worked in software development, robotics, computer vision and applied research. This professional background helps me connect classroom learning to authentic examples from technology, engineering and problem-solving. I aim to help students build confidence, computational thinking, technical vocabulary and the ability to explain their reasoning clearly.

Teaching Philosophy Extract

A short extract from my statement of educational philosophy.

Teaching philosophy extract

I believe that students learn best when teaching is clear, structured and focused on real understanding. In Computer Science, concepts are often abstract, so my role is to make them accessible, logical and meaningful while maintaining the level of challenge students need.

I use clear explanations, step-by-step modelling and regular opportunities for guided and independent practice. I want students to be active participants in learning: thinking, questioning, discussing, testing ideas and solving problems. In programming, I encourage a safe-to-fail culture where debugging is seen as a normal part of learning rather than a sign of failure.

Assessment is also an important part of my teaching. I use questioning, mini-whiteboards, written tasks and exit tickets to check understanding and identify misconceptions while learning is happening. This helps me respond during the lesson or adapt future teaching based on evidence.

In a bilingual classroom, I believe students need support with both subject knowledge and academic English. I use scaffolding, clear language, sentence stems, guided examples and technical vocabulary support so that students can access challenging learning and express their thinking more clearly.

I see teaching as a process of continuous reflection. I review lessons, student responses and learning evidence to decide where I need to adjust, refine or improve my practice.
