Jan - Know your tutor
My teaching style as a technology educator is built on the conviction that technology education should prepare students to think, create, solve problems, and act responsibly in a world where digital systems influence nearly every aspect of life. I believe that students learn best when they understand not only how technology works, but also why it matters and how it can be used to improve their communities and future careers. Rather than treating technology as a collection of isolated software skills or technical definitions, I approach every lesson as an opportunity to develop curiosity, critical thinking, collaboration, creativity, and ethical decision-making. I strive to create a classroom where students feel challenged to ask questions, experiment with new ideas, and learn from mistakes wirhout fear of failure. I recognize that every learner enters the classroom with different experiences, strengths, interests, and confidence levels, so I intentionally design instruction that provides multiple entry points for success. Whether a student dreams of becoming a cybersecurity analyst, software developer, engineer, entrepreneur, musician, healthcare professional, or simply wants to become a more informed digital citizen, I want every lesson to connect technology with authentic, meaningful applications that extend beyond the classroom walls.

Computer Science concepts taught by Jan
The tutor and student reviewed piano warm-up exercises, practiced major scales (C, D, E) with hands separately and together, and worked on ascending scales by an octave. They also engaged in note identification exercises using flashcards and began practicing measures from Mozart's Sonata K545 with a metronome, with plans to continue this piece and introduce F and G major scales, along with major chord theory, in the next session.
Note Reading and Identification
Basic Music Theory: Major Chords
Musical Repertoire: Mozart Sonata 16
Rhythm and Timing with a Metronome
Major Scales: Structure and Practice
The Student and Tutor reviewed C, D, and E major scales, focusing on proper piano technique and articulation. They then practiced Mozart's Sonata No. 16 in C major (K545), reviewing earlier measures and beginning new sections. The session concluded with an explanation and practice of building major chords using the root, major third, and perfect fifth, alongside a review of the major scale formula, with homework assigned for continued practice on scales, the sonata, and chord construction.

Building Major Chords: Structure and Examples
Effective Piano Practice Principles
The Student and Tutor reviewed how to build major scales, focusing on the D major scale's alterations, and learned to construct a C major chord by identifying its tonic, third, and fifth. They practiced new piano articulation techniques, staccato and legato, and explored musical dynamics such as allegro, crescendo, and decrescendo. Homework includes practicing the D and E major scales, and refining measures 1-17 of the sonata with the correct techniques and dynamics.

Applying Techniques to Performance
The Student and Tutor conducted a piano lesson, reviewing the C major scale and collaboratively deriving the D major scale using the tone-semitone method. They focused on refining piano technique, including wrist relaxation and crucial thumb transitions, during scale and sonata practice. Homework was assigned to practice the D major and E major scales, and specific sonata sections (compasses 11-17), emphasizing the thumb technique.

Essential Fingering & Hand Position for Fluidity
Sonata Progression & Observational Feedback
Student and Tutor engaged in an introductory piano session. They assessed the Student's current playing abilities through a performance of a sonata, reviewed basic finger techniques, practiced the C Major scale with both hands, and introduced fundamental music theory concepts like chords and scale construction using the tone-tone-semitone formula. The plan for future lessons involves building structural learning and strengthening techniques.
