They can also make the subject feel harder or less welcoming when the underlying tools are unfamiliar. What students take away depends on their experience, the format of the activity, and the outcome being measured—not simply on whether a lesson includes a challenge.
What a computing challenge can change
A challenge can change how students interpret computing as well as what they can do with it. A programming task tied to a science question, for example, may make computation feel like part of authentic scientific work. But if students are still struggling to understand the computational tools, that same task can add frustration rather than meaning.

In a 2022 study of students in a U.S. high-school physics class, Hamerski and colleagues described computation as “a double-edged sword”: it could make science learning more authentic for students already familiar with computation, while unfamiliarity could contribute to frustration and aversion toward physics. This is evidence from a particular classroom case, not a prediction of how every student will respond. Read the study in Physical Review Physics Education Research.
How the activity’s format affects the experience
Screen-based coding and physical computing offer different experiences. Physical computing means designing and programming physical systems or devices using computational-thinking skills. It can make code tangible, but the extra interaction with devices does not necessarily make the concepts feel easier.
#1 Best Overall
- TURN CODE INTO REAL-WORLD RESULTS — Follow 22+ guided lessons to make LEDs blink, read temperature and distance, move servo and stepper motors, control an LCD and respond to joystick or IR input; ideal for a family weekend build, homeschool unit, coding club or STEM classroom
- MORE PROJECT VARIETY IN ONE ORGANIZED KIT — Includes the UNO R3 controller, LCD1602 with pre-soldered header, breadboard power module, ultrasonic and DHT11 sensors, joystick, IR receiver and remote, SG90 servo, stepper motor, relay, DC motor, fan blade, displays, LEDs, buttons, resistors and jumper wires

- LEARN THE LOGIC, THEN CREATE YOUR OWN — Use Arduino IDE and the included example code to understand digital input and output, analog sensing, timing, motor control and display functions, then change thresholds, speeds and sequences for alarms, environmental monitors, reaction games and motion projects
- CLEAR SETUP SUPPORT FOR FIRST-TIME BUILDERS — Download the latest tutorial and code, select the UNO board and correct computer port, check component polarity and breadboard rows, and keep power-module input at 9V or below; younger learners should work with an experienced adult
Love and Asempapa’s 2022 study compared screen-based and physical-computing units with 170 middle-school students. Students in the screen-based group reported statistically greater attitudes toward classroom applications and the future or career use of computing concepts. Students in the physical-computing group perceived greater difficulty, yet preferred the hands-on opportunities. The published abstract does not provide effect sizes, so the findings do not establish the size of those differences.
The results point to a trade-off, not a universal winner: students can value hands-on work and still find it more difficult. Read the study in the International Journal of Child-Computer Interaction.

Why relevance and purpose matter
Students may view computing differently when they can connect it to people, communities, or goals beyond completing a coding exercise. A 2023 ACM SIGCSE study analyzed survey data from more than 45,000 undergraduates and found that the association between communal goals and belonging varied with students’ perceptions of whether computing could serve communal goals. This is an association in undergraduate survey data; it does not show that adding a social-impact challenge will change school-age students’ perceptions or belonging.
For a classroom activity, a useful question is whether students can see what the computing is for. A task connected to an authentic science investigation or a purpose students find meaningful may offer a clearer reason to engage than an isolated exercise. That is a design consideration, not a guaranteed effect. Read the ACM SIGCSE study.

Confidence, belonging, and achievement are different outcomes
Positive feelings about a task, confidence in one’s ability, a sense of belonging, participation, persistence, and exam performance are related but distinct outcomes. Evidence that one changes does not establish that the others do.
A 2026 study of an ecological belonging intervention in an introductory college computer science course found larger increases in self-efficacy among students who received the intervention. First-year students also showed a larger increase in one belonging factor, Affect. The study found no significant effects on exam performance, engagement, persistence, or other belonging factors. Because it tested an intervention rather than a challenge-based lesson format, it cannot establish that classroom challenges produce those results.

What identity findings can—and cannot—tell us
An exploratory study of multilingual upper-elementary students in a year-long computational-thinking curriculum reported favorable pre/post differences in students’ computing experiences, perceptions of computing, self-perception as computer scientists, and family support. These findings suggest that students’ views can develop in a sustained learning context, but the study’s exploratory phase does not establish lasting or broadly causal change.

How to interpret a classroom challenge fairly
- Account for prior experience. Students familiar with computation may see it as a useful way to investigate a problem; unfamiliar students may face extra friction.
- Consider format and difficulty together. Hands-on physical computing may be appealing while feeling harder, whereas screen-based work may be viewed more positively for classroom application or future use.
- Make the purpose visible. A clear connection to a question, creation, or goal can help students understand why computing is part of the work, without guaranteeing a change in attitude or belonging.
- Name the outcome precisely. An attitude measure, self-efficacy, belonging, engagement, persistence, and performance should not be treated as interchangeable evidence of success.
The studies span high-school physics, middle-school computing, multilingual upper-elementary education, undergraduate survey research, and an introductory college course. Their results describe different populations and methods; taken together, they do not identify one best challenge format or establish a universal effect.
