Introduction

• Science Shaping Paper (August 2023) recalibrates Grades 3-10 science in the MATATAG K to 10 curriculum.
• Purposes
– Narrate goals, philosophy, rationale.
– Present Big Ideas & Cross-cutting Concepts to foster durable understanding & transferable skills.
• Builds on
– 2016 K-12 Science curriculum findings.
– 2019-2020 curriculum review (issues: congestion, unequal cognitive demand, need for vertical/horizontal articulation).
• New emphases
– From "technological literacy" to technology & engineering literacy.
– Explicit Key Stage & Grade-Level Standards.
– Developmental sequencing aligned to three cognitive modes (sensorimotor → iconic → concrete-symbolic).
• Aligns with DepEd MATATAG Agenda
– $MAking$ curriculum relevant.
– $TAking$ steps for facilities.

– Support teachers to teach better.

Curriculum Goals

• Overall goal: cultivate scientific, environmental, technology & engineering literacy for all learners.
• Graduates expected to
– Participate actively in local ‑ global contexts.
– Contribute to BEDP 2030 vision of competent, job-ready, ethical citizens.

Theoretical & Philosophical Foundations

• RA 10533 mandates use of universally recognized learning theories, esp. Constructivism.
• Key supporting theories
– Social-constructivism (Vygotsky): co-construction, language mediation, cultural context, $ZPD$ with scaffolding.
– Social Cognition (Bandura): observational learning, attention-retention-reproduction-motivation cycle.
– Brain-based Learning: classroom conditions mirror how the brain learns best; optimize emotion, novelty, health.
– Cognitive Load Theory: instruction must respect limited working memory $\text{(Sweller; William 2017)}$ .
– Modes of Thinking (Biggs & Collis): sensorimotor → iconic → concrete symbolic → formal → post-formal.

Curriculum Framework

• Three inter-related content strands (always integrated in competencies)
– Scientific Inquiry Skills (planning, data, evidence, reasoning).
– Scientific Knowledge & Application (facts → concepts → laws → theories → engineering solutions).
– Scientific Attitudes & Values (curiosity, objectivity, stewardship, collaboration).
• Inquiry is central; supported by
– Applications-led contexts.
– Science-Technology-Society (STS) issues.
– Problem-based & multidisciplinary learning.
• Learner-centered, hands-on/minds-on, evidence-based explanations.
• Assessment integral, mostly formative, aligned with content & performance standards.

Big Ideas (Harlen 2015)

• Few powerful statements linking many concepts; reduce overload & improve transfer.
• Drive selection/sequence of content & ensure cognitively balanced competencies across grades.

Cross-cutting Concepts (NRC 2012)

• Applied repeatedly across domains/grades to connect ideas
– Structure & Function
– Stability & Change
– Systems & System Models
– Energy & Matter (flows, cycles, conservation)
– Scale, Proportion & Measurement
– Patterns
– Cause & Effect
– Nature & Practices of Science

Developmental Sequencing of Concepts

• Informed by

Prior experiences.
Modes of thinking progressions.
Cognitive demand of new ideas.
Language demand.
Need for reinforcement within/across domains.
• Vertical Articulation: concepts increase in complexity from Grade 3 → 10.
• Horizontal Articulation: links to languages, math, EPP/TLE, AP, etc.; literacy & numeracy underpin science.

21ᵗʰ-Century Skills Embedded

• Information, Media & Technology (visual, digital).
• Learning & Innovation (creativity, critical thinking, problem solving).
• Life & Career (decision making, resilience).
• Communication & Collaboration (teamwork, diverse contexts).

Social Issues & Government Priorities

• Integrated contexts: DRRM, climate action, environmental protection, sustainable resources, Green economy, Renewable energy, CSE.

STEM Integration & Engineering Design Process (EDP)

• Science, Math, TLE collectively employ EDP: Ask → Imagine → Plan → Create → Test → Improve.
• Learners build/test solutions, iterate, learn from failure.

Pedagogies

• Inquiry-Based Learning – questions, investigations, dialogue.
• Applications-Led – content via real-life uses.
• Science-Technology-Society – socio-cultural analysis.
• Problem-Based Learning (design thinking, EDP).
• Multidisciplinary / Inter- / Trans-disciplinary – dissolve boundaries where relevant.

Assessment & Performance Tasks

• Classroom assessment continuous; identify prior knowledge, give feedback, adjust instruction.
• Each quarter: ≥1 substantial performance task judged against Performance Standards.
• Questions addressed: What learners can do, how well, applying in real-life, evidence used.

Resources & Technology

• Supports face-to-face, distance, blended delivery.
• Encourages emerging tools: robotics, mobile apps, VR/remote labs, gamification, learning analytics.

Curriculum Organization

• Discipline-oriented domains
– Grades 3-6: Materials | Force Motion Energy | Living Things | Earth & Space.
– Grades 7-10: Science of Materials | Force Motion Energy | Life Science | Earth & Space Science.
• Quarter sequencing (simplified)
– Q1 Materials/Science of Materials; Q2 Living Things/Life Science; Q3 Force Motion Energy; Q4 Earth & Space.

Key Stage Standards (Snapshots)

• Key Stage 1 (K-3): healthy habits, curiosity; basic process skills (observe, communicate, classify, measure, infer, predict).
• Key Stage 2 (G4-6): design simple investigations, gather evidence, conclude; apply science for health & environment.
• Key Stage 3 (G7-10): demonstrate literacies, conduct authentic inquiries altering one variable, communicate findings.
