About
This quiz focuses on computer programming fundamentals, specifically function calls and code execution in a visual programming environment. Designed for 9th grade computer science students, the questions assess students' ability to trace through code and predict visual outputs when functions are called to draw shapes on screen. Students must understand how function calls work, the sequence of code execution, and how multiple function calls create layered visual elements. The core concepts required include recognizing function syntax, understanding that each function call executes independently, counting the total number of shapes generated by multiple calls, and predicting the visual layering effects when shapes overlap. Students need logical reasoning skills to mentally execute code line by line and spatial reasoning to visualize how shapes will appear when drawn in sequence, particularly understanding that later-drawn shapes appear on top of earlier ones. Created by Joan Goldberg, a Computers teacher in US who teaches grade 9. This quiz serves as an excellent formative assessment tool to gauge students' comprehension of function calls before moving to more complex programming concepts. Teachers can use it as a warm-up activity to activate prior knowledge about functions, as guided practice during instruction on code tracing, or as homework to reinforce lesson concepts about program execution flow. The visual nature of the questions makes abstract programming concepts more concrete and accessible for students who are new to coding. This assessment effectively supports classroom instruction by identifying students who may need additional support with function call syntax or code execution order, allowing teachers to provide targeted interventions. The quiz aligns with CSTA K-12 Computer Science Standards, particularly 1A-AP-10 (developing programs with sequences), 1A-AP-14 (observing intellectual property rights), and 1A-AP-15 (creating programs using variables to store and manipulate data).
