Problema Real: Ready-to-Run Interdisciplinary PBL Case Packs for Secondary Science
A collection of ready-to-use real-world science problems for high school teachers.
A catalog of authentic, ill-structured real-world science problems — each a multi-week module with staged data reveals, a facilitator guide, and both classroom and digital run variants — that lets an ordinary secondary science teacher run problem-based learning without designing it from scratch.
Concept
Each pack is built around one genuine, interdisciplinary problem that cannot be solved inside a single science discipline — e.g., 'Why are the fish dying in the town's reservoir?', 'Should our city convert its bus fleet to electric?', 'Is the old factory making our neighborhood sick?' — mirroring the real-world, interdisciplinary nature of the problems the PBL literature uses. A pack contains: (1) a student-facing problem brief with staged information releases (water-quality tables, news clippings, lab results, conflicting expert statements) that force successive inquiry cycles; (2) a facilitator guide with concrete questioning moves, grouping patterns, and 'when to step back' cues; (3) a curriculum map to the local syllabus (e.g., Brazil's BNCC, US NGSS, Indonesia's Kurikulum Merdeka); and (4) two runbooks — a face-to-face version and a digital-environment version with shared-document and discussion structures — because the source reprint shows PBL operating in both settings. Packs are sold per-unit or by annual subscription to schools and networks, and refreshed yearly with new local data so the problems stay authentic.
Why now
The new paper [0], a reprint synthesizing PBL in science education, establishes both the value and the bottleneck: PBL 'may enable students to learn content knowledge and develop competencies and abilities that are relevant for 21st-century citizens' and contributes to 'a wide range of science learning outcomes' — yet 'implementing PBL in science education requires teachers and students to change their ways of learning, teaching, and assessing learning,' and the reprint is explicitly organized around 'the challenges posed to science teachers and students.' That design-and-role-change burden is the adoption barrier: a secondary chemistry teacher has typically never written an ill-structured interdisciplinary problem, and the paper frames this as the central challenge, not a side effect. Ready-made, curriculum-mapped case packs convert the demonstrated method into a purchasable unit — the same product logic that made scripted kits viable at elementary level, applied to the secondary-science PBL gap where no equivalent exists.

AI assessment
A high-utility 'curriculum-in-a-box' that solves the primary adoption barrier for PBL in secondary science by removing the design burden from the teacher.
- Evidence strength 4/5
- The supporting research explicitly identifies the teacher's role change and design burden as the central challenge to PBL implementation, directly validating the need for ready-made packs.
- Market pull 4/5
- Large education ministries and publishers have a strong incentive to standardize high-impact methodologies like PBL across diverse teacher skill levels.
- Novelty & moat 3/5
- While similar to DiscoveryKit IPAS in its 'scripted kit' logic, it differentiates by targeting secondary interdisciplinary science and 'ill-structured' problems rather than simple inquiry.
- Feasibility 5/5
- The MVP requires content creation and curriculum mapping rather than complex technical development, making it highly feasible for a small team.
- Wedge clarity 5/5
- The 'Case Pack' is a sharp, discrete unit of value that can be piloted in a single classroom or district before scaling.
- Simplicity / focus 5/5
- The idea avoids 'platform creep' and focuses on a single, well-defined product: the interdisciplinary PBL module.

Who benefits
- Indonesian Ministry of Education (Kemendikbud)organization
Kurikulum Merdeka requires project-based learning themes in every school; curriculum-mapped PBL science packs directly serve that national requirement with ready materials.
- Secretaria de Educação do Estado de São Pauloorganization
One of Latin America's largest secondary school networks; under the BNCC competency mandate, ready-made PBL packs give thousands of teachers a feasible path to active methodology without per-teacher design time.
- Twinklcompany
A global teacher-resources marketplace whose catalog is strong on worksheets and short activities but lacks multi-week, ill-structured science problem modules; a licensed PBL pack line fills a real gap for its secondary science buyers.
- Oxford University Presscompany
Publishes secondary science courses worldwide; adding a PBL case-pack line differentiates its science catalog against competitors still selling chapter-based content.
