VideoText Geometry: A Complete Course (with Trigonometry)

MathGrades 9–12

About This Curriculum

A video-based geometry curriculum using mastery-learning techniques with interactive lessons, covering geometry fundamentals through trigonometry in a logical, sequential approach.

What makes it unique: Uses video as the primary textbook with conceptual understanding emphasized through 'why' behind concepts rather than memorization of formulas and tricks.

VideoText Geometry: Video-Based Mastery Learning with Sequential Concept Building

VideoText Geometry is a comprehensive video-based math curriculum that uses mastery learning techniques to teach geometry through trigonometry. The program features short interactive video lessons by instructor Tom Clark, with supporting workbooks and extensive solution materials designed for sequential concept building.

Best for

Homeschool students in grades 9-12 who benefit from self-paced mastery learning and families seeking comprehensive geometry through trigonometry coverage with strong instructor support

Evaluation Criteria

6 strengths · 2 neutral · 1 insufficient evidence

Worked ExamplesStrength

Worktext exercises include complete worked solutions and examples before students attempt independent practice.

Reviews mention that worktext exercises present examples with complete solutions before students begin actual exercises, and a complete Solutions Manual is available for checking work

Direct InstructionStrength

Provides clear direct instruction through video lessons with instructor explanations, designed for interaction and discussion.

Reviews describe thorough explanations by instructor Tom Clark, with students stopping videos to answer questions and discuss concepts with parent/teacher

Retrieval PracticeStrength

Includes quizzes and progress tests with multiple versions, ensuring students demonstrate retention before advancing.

Reviews mention quizzes given before new lessons to ensure concept retention, separate book of quizzes and tests with two versions each for retesting, and progress tests in instructor guides

Sequencing ApproachStrength

Uses effective mastery-based sequencing with logical progression from fundamentals through advanced concepts without shortcuts.

Reviews praise the mastery approach over spiraling, noting VideoText builds logical, well-explained concepts without shortcuts or tricks, with students taking at least two days per lesson to ensure mastery

Assessment DiagnosticStrength

Includes regular quizzes and progress tests to check understanding, with retesting options available.

Reviews describe quizzes before new lessons, progress tests, and two versions of each test for retesting if needed, allowing identification of problem areas through solution manuals

Conceptual Procedural BalanceStrength

The curriculum emphasizes conceptual understanding through building-block progression, starting with fundamental terms and reasoning before moving to formal proofs and procedures.

Reviews note the goal is to develop conceptual understanding through a building blocks fashion, working through fundamental terms, definitions, logic, and reasoning before formal proofs

Teacher TrainingNeutral

Provides instructor guides with detailed solutions and course structure, though limited pedagogical guidance is evident.

Reviews mention Instructor's Guide with Detailed Solutions for Progress Tests and course notes, but limited mention of mathematical background or misconception guidance

Visual RepresentationsNeutral

Video lessons include animations and visual explanations, though specific manipulative use is not detailed.

Reviews note that instructor Tom Clark uses examples and animations in video presentations to explain concepts

Word ProblemsInsufficient Evidence

Limited evidence of systematic word problem instruction in the available reviews.

Reviews focus on geometric concepts, proofs, and trigonometry but do not specifically mention word problem schemas or real-world application strategies
