Start with a question that needs action
This is original GAC031-aligned practice for unit 3.2, School Service PBL Planning. It continues the fictional library project from unit 3.1. It is not an ACT assessment.
The team first writes: “How can we make the library better?” This driving question 驱动性问题 is too wide. It does not name a user 用户 or a problem the team could test. After speaking to students who need silence and students who need to discuss work, they rewrite it: “How can students find the right quiet or discussion area within two minutes during exam week?” Now they can make a sign system, ask people to use it, and see what happens.
A project is more than a poster. The poster is a possible deliverable 交付成果; helping students find an appropriate space is the aim. If a poster fails, the aim stays and the team can try a different solution.
“Make the library better” is so wide even a book cart could get lost in it.
Which driving question can the library team answer through a small project? · ¿Qué pregunta motriz puede responder el equipo de la biblioteca a través de un pequeño proyecto?
The second question names a user, a concrete difficulty and a result that a sign or other design can be tested against. · La segunda pregunta nombra un usuario, una dificultad concreta y un resultado contra el cual se puede probar un letrero u otro diseño.
Find a starting point before setting a target
The team asks 20 volunteers who have not seen the proposed signs to find a suitable space. Nine do so in under two minutes. This baseline · línea base (baseline) 基线 is a starting observation, not a judgement about every library user. The group sets a success criterion 成功标准: after a one-week sign trial, at least 16 of 20 new volunteers should find the right space within two minutes, using the same starting point and instructions.
The numbers are small. Even if 16 succeed, the team should say “our trial suggests the signs helped these testers,” not “the signs will help everyone.” They also ask one open question: “What made the choice difficult?” The answer may reveal a problem a stopwatch misses, such as an unclear room label.
The baseline was 9 of 20. The target is 16 of 20. How many MORE successful attempts does the target require in a group of 20? · La línea base fue de 9 de 20. La meta es de 16 de 20. ¿Cuántos intentos exitosos MÁS requiere la meta en un grupo de 20?
16 − 9 = 7. This arithmetic describes the target difference, not proof that the signs caused an improvement. · 16 − 9 = 7. Este cálculo aritmético describe la diferencia objetivo, no la prueba de que los letreros causaron una mejora.
Name constraints and get permission
The team plans twelve days, including a full one-week sign trial, and has a small materials budget. The librarian must approve locations before any sign goes up. Signs may not block exits or cover existing safety information. These are constraints 约束条件: limits the team must respect while designing. The team records them before buying materials, because a beautiful sign that cannot be put up is not a useful result.
They record counts and comments, but no names, photographs or personal timetables. Participation in the trial is voluntary. If somebody declines, the team thanks them and asks another person; it does not treat refusal as failure. Responsible planning includes how information is gathered, not just what will be built.
Do not announce a trial before the librarian agrees to it. “We can probably get permission later” is a risk, not a plan.
Which TWO requirements must the team respect before putting up signs? · ¿CUÁLES DOS requisitos debe respetar el equipo antes de colocar los letreros?
Permission and safety are stated constraints. The project deliberately avoids personal names and must not rewrite its target after the trial. · El permiso y la seguridad son restricciones establecidas. El proyecto evita deliberadamente los nombres personales y no debe reescribir su meta después de la prueba.
Work backwards from the sharing date
A milestone 里程碑 is a checkable point in the project, not “work on signs.” The team writes a short plan:
| When | Milestone | Evidence that it is done |
|---|---|---|
| Days 1–2 | Ask users and record the baseline | Twenty timed attempts and brief anonymous notes |
| Day 3 | Sketch two sign options | Two readable sketches with proposed locations |
| Day 4 | Ask the librarian to check safety and placement | Approved locations or written changes needed |
| Day 5 | Put up the approved version | Signs in place; start time recorded |
| Days 5–11 | Run the same task during the one-week trial | Twenty new attempts and anonymous comments |
| Day 12 | Share results and a revision proposal | A one-page summary with limits and next step |
The day-4 approval is a dependency 前置条件: the team cannot honestly mark day 5 complete without it. They assign one person to arrange the check, one to prepare the signs, and two to collect observations. Everyone knows who owns each task, but the whole group reviews the result. If approval or installation is delayed, move the trial and sharing dates openly rather than silently reducing the planned trial period.
Put the key milestones in the order that respects their dependencies. · Coloca los hitos clave en el orden que respete sus dependencias.
The baseline informs the sketches; approval must precede posting; testing follows the actual change. · La línea base informa los bocetos; la aprobación debe preceder al posteado; la prueba sigue al cambio real.
Put the plan on one page
The project charter 项目章程 is a short shared record: question → users → starting evidence → target → deliverable → constraints → milestones → roles → review date. Its purpose is to make a decision visible, not to predict every problem.
If the librarian rejects a sign location, the team revises the sketch before printing. If the trial reaches only 13 of 20, they do not change the target after seeing the result. They compare the nine-person baseline with the new result, read the comments, and decide what to test next. A result below the target can still teach the team something useful if the measurement and the limits are reported honestly.
Good planning says what the team will make, how a real user will try it, what must be approved, and what evidence will tell the team to revise.
If 16 of 20 new volunteers succeed, the team can claim the signs will help every library user. · Si 16 de 20 nuevos voluntarios tienen éxito, el equipo puede afirmar que los letreros ayudarán a cada usuario de la biblioteca.
A small volunteer trial supports a limited claim about these testers. It does not establish a result for every student or prove causation. · Una pequeña prueba con voluntarios respalda una afirmación limitada sobre estos probadores. No establece un resultado para cada estudiante ni prueba la causalidad.
