Lesson Name:

Introduction to Repl.it and Python

TEKS – §126.33 (Computer Science 1):

  • c.2 – Communication and collaboration. The student communicates and collaborates with peers to contribute to his or her own learning and the learning of others. The student is expected to:
  • c.2.A – create and properly display meaningful output
  • c.2.D – write programs with proper programming style to enhance the readability and functionality of the code by using meaningful descriptive identifiers, internal comments, white space, spacing, indentation, and a standardized program style
  • c.4 – Critical thinking, problem solving, and decision making. The student uses appropriate strategies to analyze problems and design algorithms. The student is expected to:
  • c.4.E – identify reusable components from existing code
  • c.4.H – identify and debug errors
  • c.4.I – test program solutions with appropriate valid and invalid test data for correctness
  • c.4.J – debug and solve problems using error messages, reference materials, language documentation, and effective strategies
  • c.6 – Technology operations, systems, and concepts. The student understands technology concepts, systems, and operations as they apply to computer science. The student is expected to:
  • c.6.V – compare and contrast strongly typed and un-typed programming languages

Lesson Objectives:

  1. The student will be able to create a functional user account on repl.it and join the Computer Science 1 on repl.it.
  2. The student will be able to create a basic literal output application in Python of “Hello World”.
  3. The student will be able to create a basic literal output application in Scratch of “Hello World”
  4. The student will compare and contrast the process and output of “Hello World” in both programming languages.

Materials Needed:

  1. Repl.it Access
  2. Scratch Access

Description of Lesson:

Students will create user accounts on repl.it for programming in Python. Students will join the Computer Science 1 class on repl.it. Students will then create a basic literal Python output program. while also creating the same program in Scratch. Students will create “Hello World” and compare and contrast in both programs.

Grade(s):

  • Daily Grade – Creation of Repl.it Account and Joining Class
  • Quiz Grade – Compare and Contrast Hello World in both Scratch and Python
