On the new TOEFL iBT (January 21, 2026 update), Speaking Task 3 is a campus-related integrated task that asks you to summarize a reading passage, connect it to a lecture or conversation, and deliver a clear academic explanation in 60 seconds. This page provides four complete model responses targeting the computer science algorithms theme, aligned with the current 1–6 CEFR and 0–30 dual-scale scoring.
Reading (45 seconds to read): A campus bulletin announces a new student-run tutoring program called "AlgoLab." The program pairs upper-level computer science majors with first-year students to teach foundational algorithm design. The coordinator explains that many freshmen struggle with pseudocode, time complexity, and debugging logic. By practicing step-by-step problem breakdowns with peer mentors, beginners will build computational thinking faster and reduce course withdrawal rates.
Lecture (60 seconds): A professor in the computer science department discusses the announcement. He agrees with the tutoring goal but argues that the method described in the reading overlooks a crucial teaching strategy: using visual flowcharts before writing pseudocode. He explains that when students map out decision trees, loops, and base cases graphically, they internalize algorithm structure more quickly. He gives an example from his own introductory course where students who sketched flowcharts solved sorting problems 30% faster during exams. He concludes that the tutoring sessions should integrate diagramming first, then transition to code.
Task: Summarize the reading and explain how the professor responds to it. You have 30 seconds to prepare and 60 seconds to speak.

The reading introduces a new campus program called AlgoLab that helps first-year computer science students learn how to design algorithms by pairing them with older students. The main goal is to improve their computational thinking and stop them from dropping out of the course. The professor in the lecture has a different opinion about the teaching method. He thinks the program should use visual flowcharts before students start writing pseudocode. He says that when learners draw out the steps, loops, and conditions on paper, they understand the algorithm structure better. He gives an example from his class where students who made diagrams solved sorting questions faster on tests. He suggests that the tutoring sessions should combine drawing first and then coding. This way, beginners will learn more efficiently and feel more confident when facing complex problems in their exams. I think his idea makes sense because many students find abstract code confusing at first, and pictures help them organize their thoughts before typing any syntax.

The campus announcement describes AlgoLab, a peer-tutoring initiative designed to support freshmen who struggle with algorithm design, pseudocode, and debugging. The reading emphasizes that guided practice with upperclassmen will strengthen computational thinking and lower withdrawal rates. The professor, however, challenges the instructional approach proposed in the bulletin. He contends that students should construct visual flowcharts before attempting to write pseudocode. According to him, mapping decision branches, iterative loops, and termination conditions graphically allows learners to internalize algorithmic architecture more rapidly. To support his position, he references a controlled comparison from his own introductory section: students who drafted flowcharts completed sorting and searching tasks thirty percent faster on midterm assessments. Consequently, he recommends that AlgoLab tutors begin each session with diagramming exercises before transitioning to syntax practice. His perspective adds a crucial pedagogical layer, demonstrating that visual scaffolding directly accelerates structural comprehension in novice programmers.

The university bulletin introduces AlgoLab, an initiative that matches first-year computer science students with advanced peers to improve their grasp of algorithm design and reduce course attrition. The reading attributes potential success to structured peer mentoring and iterative pseudocode practice. The professor, conversely, questions the pedagogical sequence outlined in the announcement. He maintains that visual mapping must precede syntactic translation. Specifically, he argues that sketching flowcharts—complete with conditional branches, recursive loops, and exit criteria—enables beginners to conceptualize algorithmic flow before grappling with programming syntax. He substantiates this claim by citing performance metrics from his own introductory cohort: students who practiced diagrammatic planning outperformed their peers by roughly thirty percent on timed sorting assessments. Accordingly, he urges the tutoring coordinators to embed flowcharting as a mandatory preliminary step. By prioritizing structural visualization, the program would not only accelerate comprehension but also mitigate the cognitive overload that typically causes freshmen to abandon introductory computing courses.

The posted campus notice outlines AlgoLab, a peer-mentoring scheme intended to scaffold algorithmic reasoning for first-year computing students and curb dropout rates through guided pseudocode drills. While the reading assumes direct coding practice with experienced tutors will suffice, the lecturer disputes this methodological assumption. He advocates for a diagram-first pedagogical sequence, arguing that novices must externalize algorithmic logic visually before translating it into textual syntax. By charting conditional branches, iterative structures, and base cases, learners construct a mental blueprint that reduces syntactic confusion and working-memory strain. To validate this approach, he references a classroom experiment where students who drafted flowcharts prior to coding resolved sorting and traversal problems thirty percent faster on proctored assessments. He therefore recommends that AlgoLab sessions mandate flowchart generation as a prerequisite step. Integrating this visual scaffolding not only aligns with established cognitive load theory but also transforms abstract computational procedures into tangible, sequential actions, ultimately producing more resilient introductory programmers.
