OSAT Computer Science (OK181) study guide
OSAT Computer Science (OK181) · Work through your exam, one topic at a time.
The OSAT Computer Science (OK181) is a subject-area assessment used in Oklahoma's teacher certification pathway for candidates who want to teach computer science at the secondary level. It is typically taken by people completing an educator preparation program, career-changers with industry computing experience, and certified teachers adding a computer science endorsement. The OSAT Computer Science (OK181) study guide has 7 sections and about 2,405 words.
01Computer Science Foundations and Computational Thinking
Computer Science Foundations and Computational Thinking asks you to move between human problem statements and machine representations. Items target number bases, Boolean logic, data encoding, hardware and software basics, and the computational-thinking practices of decomposition, pattern recognition, abstraction, and algorithm design.
339 words, about 2 min02Programming Fundamentals and Algorithm Design
Programming Fundamentals and Algorithm Design covers how a solution is expressed and checked: variables and types, control structures, functions and parameters, scope, recursion, pseudocode, tracing, debugging, and basic algorithm design. The exam favors code reading and output prediction over syntax trivia.
350 words, about 2 min03Data Structures and Algorithms
Data Structures and Algorithms tests selection and analysis: arrays, linked lists, stacks, queues, trees, hash tables, and graphs, plus searching, sorting, traversal, and Big-O. You should be able to choose a structure from its operation costs and trace an algorithm step by step.
355 words, about 2 min04Computer Systems, Networks, and Security
Computer Systems, Networks, and Security connects hardware, operating systems, network protocols, and defensive security. Expect items on the fetch–decode–execute cycle, memory hierarchy, IP addressing and subnetting, TCP/IP layers, common protocols, and the confidentiality–integrity–availability triad.
314 words, about 2 min05Data Management and Analysis
Data Management and Analysis covers relational databases, SQL, keys and normalization, data cleaning, aggregation, and responsible interpretation. You need to read schemas, predict query results, and recognize when a visual or statistic misleads.
330 words, about 2 min06Impacts of Computing, Ethics, and Professional Practice
Impacts of Computing, Ethics, and Professional Practice asks you to reason about consequences, not just recall definitions. Items cover privacy, bias, accessibility, the digital divide, intellectual property, licensing, school law such as FERPA and COPPA, and professional codes such as the ACM Code of Ethics.
345 words, about 2 min07Computer Science Instruction and Assessment
Computer Science Instruction and Assessment tests pedagogical content knowledge: how to sequence CS concepts, surface misconceptions, design inclusive instruction, and gather valid evidence of learning. Expect items on standards, formative and summative assessment, rubrics, differentiation, and equitable participation.
