Let's Talk About Your Project

Our Content Development Capabilities

Whether you’re building a K–12 curriculum, a higher education program, or workforce learning at scale, Six Red Marbles develops content that is rigorous, engaging, and built to last. We combine deep subject-matter expertise, learning science, and real-world delivery experience to create content that works for learners and for the organizations that serve them. We partner closely with clients to design content from the ground up or strengthen existing programs, always keeping pedagogy, standards, accessibility, and outcomes at the center.

Curriculum Design

Cohesive, learner-centered curricula grounded in pedagogy and built to scale.

Strong curriculum design is intentional, cohesive, and grounded in how people actually learn. We design curricula that align learning goals, instructional strategies, and assessment into a clear, scalable experience supporting both learner success and instructional sustainability. Our teams balance pedagogical rigor with real-world delivery needs, ensuring programs are usable, adaptable, and built to last.

Services include:

  • Scope and sequence development
  • Program- and course-level design
  • Syllabi and lesson planning
  • Content mapping across print, digital, and hybrid modalities
  • Integration with learning experience design and creative teams

Assessment Writing

Instructionally aligned assessments that measure learning and support meaningful outcomes.

Assessment should do more than measure performance. It should support learning and inform instruction. We design assessments that are instructionally aligned, cognitively appropriate, and meaningful for learners and educators alike. From individual items to full assessment systems, our work emphasizes clarity, validity, and actionable insight.

Services include:

  • Assessment and item authoring
  • Alignment to learning objectives and standards
  • Difficulty, complexity, and DOK leveling
  • Detailed rationales, rubrics, and exemplars
  • Adaptive and personalized assessment solutions
  • Item banks and gap analysis

Editorial Development

Editorial rigor that ensures clarity, consistency, and instructional integrity at scale.

High-quality content depends on strong editorial foundations. Our editorial teams ensure instructional clarity, consistency, and accuracy across every asset, while maintaining voice, tone, and pedagogical intent. We scale editorial rigor to meet the demands of complex, multi-author, and multi-format programs.

Services include:

  • Developmental and line editing
  • Copyediting and proofreading
  • Fact-checking and source verification
  • Bias and DEIA review
  • Editorial workflow design for large-scale programs

Standards Alignment

Thoughtful alignment that connects learning objectives, instruction, and required frameworks.

Standards alignment is both a technical and instructional discipline. We align content thoughtfully and transparently, ensuring learning objectives, instruction, and assessment map clearly to required frameworks—while still supporting meaningful learning experiences.

Services include:

  • State and national standards alignment (Common Core, NGSS, WIDA, and more)
  • Higher education and professional frameworks
  • Standards correlation and documentation
  • Alignment audits for existing content

Multilingual Content

Localized, transadapted content designed for instructional clarity and multicultural reach.

Multilingual content requires more than direct translation. It requires instructional and cultural intention. We develop and adapt content that supports multilingual learners and audiences while preserving rigor, clarity, and pedagogical effectiveness.

Services include:

  • Transadaptation, translation, and localization
  • Multilingual curriculum development
  • Cultural and linguistic review
  • Support for ELL/ELD and SLA frameworks

Accessibility

Accessible-by-design content that supports inclusive learning without sacrificing quality.

Accessibility at Six Red Marbles is designed in from the start. We approach accessibility through a pedagogical lens, ensuring content is inclusive, usable, and instructionally sound. Our work supports both learner access and institutional requirements.

Services include:

  • Pedagogically accessible content design
  • WCAG 2.0 A, AA, and AAA alignment
  • Section 508 compliance support
  • Accessibility audits and remediation
  • Collaboration with accessibility and QA partners
