SHS2 Computing · Semester 1 Week 1: Data Storage and Manipulation

Lesson notes

Learning Objectives

Indicator: 2.1.1.LI.1 - Determine critical points of Logic Operations and apply them to solve problems efficiently.

By the end of the lesson, learners can:

State the three basic logic operations (AND, OR, NOT) and identify their truth table outputs.
Determine the critical points (the essential decision points) in a logic operation problem by translating a real-world condition into a logic expression.
Apply AND, OR, and NOT operations to evaluate simple logic expressions and produce correct outputs.
Construct a simple decision flowchart that uses logic operations to solve a given problem.
Justify which logic operation is most appropriate for a given scenario and explain their reasoning to peers.

Exemplars (from the NaCCA curriculum)

Group Work/Collaborative Learning: Identifying and discussing Mass Storage Media: Engage in interactive presentations, video analysis, and debates by dividing the class into mixedability groups. Task the groups with identifying, classifying, and discussing three different Mass Storage Media. Ensure the group promotes inclusivity and equity, considering the needs of individuals with visual impairment, dyslexia, dysgraphia, and other diverse learning needs.
SEL: When teaching students about Logic Operations, you can integrate Social Emotional Learning (SEL) principles to create an engaging and supportive learning experience. Here are some SEL features you can incorporate into this specific topic:
Self-awareness:
- provides opportunities for self-assessment of their skills and progress in applying these concepts to manipulate data.
- helps students to recognise their emotions and attitudes towards the topic, supporting their self-confidence and self-efficacy.
Self-management:
- guides students in setting goals and planning their work
- fosters resilience and perseverance by supporting students in managing challenges and setbacks they may encounter during the learning process.
Social awareness:
- promotes collaborative learning by assigning group projects or activities to learners
- encourages students to share their knowledge and expertise with their peers, creating a supportive learning community.
Relationship skills:
- promotes teamwork and collaboration by encouraging students to work together to solve complex problems and share their insights and solutions.
- emphasises the value of giving and receiving constructive feedback
Responsible decision-making:
- encourages learners to make informed decisions.
- encourages critical thinking and reflection
Teaching and Learning Materials:
- * Notepad or exercise book * Pen * Smartphones * Laptops
- * Desktop computers * Tablets * TV and Radio
- Open Educational Resources (including YouTube, MOOCs -
- Udemy/Coursera, Khan Academy, and TESSA)
- * The iBox/iCampus (CENDLOS) * Productivity tools ix. Subject-based application software
- Instructional Laboratories (with multimedia equipment and smartboards)
- Maintenance and repair workshops
