Computer Science 2, Semester B

Course Description

Computer Science 2B is the second course of a two-semester series that extends students’ understanding of the Java language and general programming concepts, as well as advanced concepts like hexadecimal numbers, ArrayLists, multi-dimensional arrays and Boolean logic. In Computer Science 2B, students build a class project which consists of a minimum of three files. In the first lessons, examples are provided which the students examine and make modifications to them. In later lessons, students are led through the process of creating their own files, which are components of a project of their own choosing. In the final lesson, students turn in their project, which is graded per a rubric. The experience of building this class project is intended to build students’ skill and confidence in programming.

• Units: Each unit includes multiple lessons and graded assignments as well as ungraded practice quizzes to help you check your understanding of the material.
  
  
• Summative Assessments: Each course includes two online, virtually proctored summative assessments testing your understanding of the material presented in the preceding 2-3 Units.
  • Format: Online, Multiple-choice
  • Time Allowed: 1 hr 30 min
    
    
• Final Exam: Each course includes an online, virtually proctored final exam testing your knowledge of all material presented in the course.
  • Format: Online, Multiple-choice
  • Time Allowed: 3 hrs 20 min

Course Grade Weighting

Your final course grade is calculated by weighting the three assignment groups displayed in the table below:

Online Proctored Exams

All course exams, including both summative assessments and the final exam, must be completed online. Students must test online with Proctorio and are required to add the Proctorio extension to either their Microsoft Edge or Google Chrome browser—installation instructions are provided in the student's course. Proctorio uses a student's computer, web camera, and microphone to record video of both the student and their desktop during the exam. Then, UTHS instructors review the student's exam video data collected by Proctorio. Only authorized UTHS staff and instructors can view the exam recordings. Student data is not shared with any persons or organizations outside of UTHS and are deleted after one year. We encourage you to visit Proctorio's Data Security and Privacy site pages to learn more about how we protect student date.
