9.3 Supporting Strategies & Differentiated Instruction

Six Strategies for Supporting Student Learning

ETS names six strategies for supporting student learning: modeling, developing self-regulation skills, scaffolding, differentiating instruction, guided practice, and coaching. They work together as a progression from teacher support toward student independence.

A central principle: a scaffold is temporary. When students use a support effectively, the next step is to withdraw it and ask them to do that part themselves. Leaving scaffolds in place indefinitely creates dependence. This section then examines differentiated instruction in depth, since ETS's case tasks repeatedly ask candidates to meet the needs of a wide range of learners.

Theoretical Foundations: Carol Ann Tomlinson's Model

Differentiated instruction is an instructional philosophy and pedagogical model developed extensively by Carol Ann Tomlinson. Rather than viewing a classroom as a monolithic collective that must be taught identically, differentiated instruction recognizes that secondary classrooms encompass a wide spectrum of cognitive readiness, background knowledge, linguistic proficiencies, cultural traditions, and adolescent interests. Tomlinson defines differentiation as a teacher's proactive response to learner needs shaped by mindset, guided by general principles of differentiation, and enacted through adjustments to curricular elements.

Differentiated instruction is firmly anchored in Lev Vygotsky's Zone of Proximal Development (ZPD). Vygotsky posited that optimal cognitive growth occurs when learning tasks are situated just beyond a student's current independent mastery level, requiring instructional scaffolding to achieve success. If an instructional task is far above a student's ZPD, the learner experiences acute frustration and cognitive shutdown. Conversely, if a task falls well below the student's ZPD, the learner experiences boredom and cognitive stagnation. In a heterogeneous high school class, a single standardized assignment cannot simultaneously reside within the ZPD of every adolescent. Differentiation provides the pedagogical mechanisms to calibrate challenge and support dynamically.

The driving engine of differentiated instruction is continuous formative assessment. Formative assessment is not merely an evaluative event at the end of a unit; rather, it is an ongoing diagnostic compass. Teachers employ pre-assessments (diagnostic assessments administered before instruction) to establish baseline student readiness, deploy ongoing formative checks during instruction (exit tickets, think-pair-share, brief polls, quick-writes) to track conceptual growth, and utilize summative assessments to evaluate cumulative mastery.

The Four Curricular Elements of Differentiation

Tomlinson's model identifies four primary classroom elements that secondary educators can modify to meet adolescent learning needs:

1. Content: What Students Learn and Access

Content encompasses the knowledge, concepts, facts, principles, and skills that students are expected to learn, as well as the instructional mechanisms through which they access that information. While state standards dictate the core goals, the vehicles through which content is delivered can be varied:

• Leveled and Multi-Lexile Texts: In an 8th-grade social studies unit exploring the American Industrial Revolution, the teacher provides three textual versions of an archival speech: an unabridged primary document, a modern English transcription, and a version with simplified sentence structures and side-margin vocabulary glossaries. Crucially, all three texts convey identical historical arguments and thematic concepts, enabling every student to participate in the ensuing seminar.
• Curriculum Compacting: A targeted strategy specifically designed for high-achieving or gifted learners. Before launching a unit on quadratic equations in Algebra I, the teacher administers a rigorous pre-assessment. Students who demonstrate 90% or higher mastery are excused from redundant introductory lectures and repetitive homework. Instead, their curriculum is "compacted," freeing instructional time to engage in advanced, self-directed mathematical investigations, such as modeling real-world physics trajectories using parabolic vectors.
• Learning Contracts: Negotiated formal agreements between the secondary educator and an individual student or small cohort. A learning contract outlines specific learning standards to be mastered, student-selected resources, working deadlines, and benchmarks for self-assessment, granting the student autonomy over the pace and order of content acquisition.

2. Process: How Students Make Sense of Ideas

Process refers to the cognitive activities, sense-making exercises, and instructional tasks students undertake to internalize, question, and assimilate complex content into their cognitive schemas. Sense-making is essential; students do not truly own concepts until they manipulate, analyze, and apply them.

• Tiered Activities: The cornerstone of process differentiation. In a tiered activity, the teacher creates two or three levels of a task that share an identical fundamental learning objective and essential question, but vary in their level of abstractness, complexity, open-endedness, and required scaffolding. For example, during a 9th-grade biology lab on cellular respiration, all tiers investigate metabolic rates. Tier 1 students follow a semi-structured protocol with guided data tables and visual cues; Tier 2 students follow a standard inquiry protocol requiring independent variable graphing; Tier 3 students are tasked with designing their own experimental setup to test an unpredicted variable (e.g., pH variance on yeast metabolism) with open-ended hypothesis testing.
• Differentiated Graphic Organizers: Providing varying scaffolds for information synthesis. Striving students receive a structured cause-and-effect organizer with partially completed sentence starters and directional arrows, while advanced students receive an open relational matrix requiring them to map multi-causal historical feedback loops.
• Interest-Based Learning Stations: Secondary classrooms feature designated stations where students rotate to explore an overarching concept through distinct lenses (e.g., in a literature unit on dystopian fiction, one station examines governmental surveillance through technology, another analyzes sociological class stratification, and a third evaluates historical propaganda posters).

3. Product: How Students Demonstrate Mastery

Product refers to the culminating assessments, tangible artifacts, or performance tasks through which secondary learners demonstrate their depth of understanding, synthesis, and application of unit standards.

• Choice Boards and Tic-Tac-Toe Product Menus: A structured grid of nine assessment tasks aligned to specific learning targets. Students choose three contiguous options to form a line (like Tic-Tac-Toe) or pick one task from designated cognitive categories. In a 10th-grade geometry unit on spatial geometry, choices might include: constructing a 3D architectural scale model with surface-area calculations, authoring a step-by-step digital construction manual for a contractor, or coding a computer algorithm that calculates volumetric displacement.
• RAFT Assignments (Role, Audience, Format, Topic): A powerful, highly differentiated product strategy that combines creative expression with rigorous domain analysis. Each student (or the teacher) selects a specific configuration of four variables:
  • Role: Who are you speaking/writing as? (e.g., Galileo Galilei, a red blood cell, an abolitionist newspaper editor)
  • Audience: Whom are you addressing? (e.g., the Roman Inquisition, a sedentary human heart, undecided voters in 1860)
  • Format: What physical or digital genre will you produce? (e.g., a formal legal defense brief, an urgent biochemical dispatch, a newspaper broadside)
  • Topic: What core concept or conflict is being examined? (e.g., defending heliocentrism, pleading for cardiovascular exercise, arguing against the Fugitive Slave Act)
• Tiered Rubrics: While product formats may vary, rubrics share identical core assessment criteria evaluating conceptual mastery, evidence usage, and analytical precision, ensuring equitable grading rigor.

4. Learning Environment: The Physical and Affective Climate

The learning environment encompasses both the physical configuration of the classroom and the socio-emotional climate that dictates how students interact, risk failure, and collaborate.

• Physical Configuration: Creating diverse physical micro-zones within a secondary classroom, including quiet, independent study carrels with noise-dampening headphones; round tables for collaborative group deliberation; standing desks; and an open carpeted or tech-equipped zone for digital media production.
• Psychological Climate: Cultivating an atmosphere of psychological safety, mutual respect, and growth mindset. The teacher explicitly normalizes mistakes as essential data points in the learning process and ensures that all assigned tasks are "respectful tasks"—meaning every student, regardless of tier, engages in meaningful, cognitively rich work rather than demeaning, low-level drill.

Differentiating According to Student Traits: Readiness, Interest, and Profile

Readiness and the Zone of Proximal Development

Readiness refers to a student's current knowledge, conceptual understanding, and skill level in relation to a specific learning target. It is critical to recognize that readiness is not synonymous with fixed general ability or IQ. A student may exhibit advanced readiness in mathematical algebraic reasoning while exhibiting low readiness in written narrative composition. Assessing readiness requires continuous diagnostic data collection (e.g., pre-tests, skill inventories, KWL charts) to place students in their optimal ZPD.

Interest and Adolescent Motivation

Adolescent psychology dictates that intrinsic motivation surges when learning connects directly to personal passions, extracurricular hobbies, cultural concerns, and future career aspirations. Differentiating by interest involves integrating student passions into the curriculum without compromising rigor. For example, during an 11th-grade physics unit on momentum and kinetic energy, students select an area of personal interest to analyze: the biomechanics of soccer headers, the engineering of roller coaster loops, automotive crash safety systems, or competitive skateboard half-pipe physics.

Learning Profile and Sociocultural Considerations

Learning profile addresses how a student processes information, interacts with others, and works most effectively. It is shaped by:

• Cultural Orientations: Cultural preferences for collaborative communal learning (interdependence) versus solitary, competitive learning (individualism); oral storytelling traditions versus written analytical discourse.
• Environmental Preferences: Environmental requirements regarding ambient lighting, acoustic levels, physical movement, and temperature.
• Cognitive Processing Habits: Preferences for inductive discovery (moving from specific examples to general rules) versus deductive reasoning (starting with an overarching principle and applying it to cases); holistic/big-picture orientation versus sequential/detail-oriented analysis.

Common Pitfalls and Exam Traps

• Pitfall 1: "Watering Down" the Curriculum for Struggling Learners: The most pervasive differentiation error on the Praxis PLT exam is lowering cognitive demand. When a teacher asks struggling 9th graders to merely match vocabulary definitions while advanced peers synthesize multiple primary texts, the teacher is not differentiating—they are denying struggling students access to essential grade-level standards. True differentiation maintains identical cognitive complexity (e.g., analysis, evaluation) while modifying the degree of scaffolding and support.
• Pitfall 2: "More of the Same" Busywork for Advanced Learners: Giving a gifted high school student 50 geometry proofs instead of 25, or requiring them to clean beakers or act as an unpaid "peer tutor" for struggling classmates whenever they finish early, represents a failure of differentiation. Advanced learners require greater depth, abstractness, novelty, and complexity, not increased volume of routine work.
• Pitfall 3: Static, Permanent Ability Tracking: Assigning students to fixed, immutable "low," "middle," or "high" reading groups or math tracks stigmatizes adolescents, damages academic self-efficacy, and exacerbates systemic achievement gaps. Differentiation requires fluid, dynamic regrouping that shifts constantly based on diagnostic formative data.
• Pitfall 4: Grading on Effort Alone or Grading Different Tiers on Inequitable Scales: A student completing a Tier 1 scaffolded assignment must be capable of earning the highest grade if they achieve full mastery of the underlying standard. Grading must reflect progress toward and mastery of essential standards, not compliance or task volume.
