Practical Scratch Block Programming exams with answer and project activities and more for Year 7

In Term 1- This course is designed to provide students with fundamental Knowledge related to computer science. It also introduces students to Computational thinking and how computers work. In Term 2 - introduce students to computer programming and games in a fun and exciting way. The Scratch software used in this transition unit was designed with this goal in mind. Students will be able to write their own programs, animations and stories in a matter of minutes. Students will learn how to plan and design projects. They will learn how to work together on a plan in teams and they will have the opportunity to present their work to their peers and teachers. They will learn how to respond and react to feedback. They will research a project on the Internet and learn how to evaluate information on websites. In Term 3 - introduce students to computer programming and games in a fun and exciting way.

This course adopts a step-by-step, project-based approach to teach students level 2 Java programming and concepts and skills for creating simple compute programs using java programming language. Java’s unique architecture enables programmers to develop a single application that can run across multiple platforms reliably seamlessly. In this hands-on course, students gain extensive experience with Java and its object-oriented features. Students will be able to explore and use classes, use methods and develop syntax to create windows components and change appearance of the components also Students learn to create robust console and GUI applications.

In Term 1- This course is designed to provide students with fundamental Knowledge related to computer science. It also introduces students to Computational thinking and how computers work. In Term 2- This course defines the competency level require to understand and explore the basic programming concepts/ principles while using a friendly mobile app creation environment (Blockly games programming), which mainly designed to create simple animations and fun games. It enables the learner to write scripts on mobile devices and traditional PCs. By going through this course, learners shall be well prepared to move on to HTML5, JavaScript, and more. In Term 3- This course defines the competency level require to understand and explore the basic programming concepts/ principles while using a friendly mobile app creation environment (Blockly games programming), Blockly Games is a series of educational games that teach programming. It is designed for students who have not had prior experience with computer programming. By the end of these games, players are ready to use conventional text-based languages which mainly designed to create simple animations and fun games. It enables the learner to write scripts on mobile devices and traditional PCs. By going through this course, learners shall be well prepared to move on to HTML5, JavaScript, and more.
