1Lecture is an independent educational project focused on helping readers understand biology through clear explanations, visual learning, and connected lessons. This policy sets the standards for selecting, developing, checking, and maintaining our content.
Our starting focus is cell biology and biochemistry, with a broader direction that includes genetics, physiology, microbiology, and immunology. Editorial decisions should serve the needs of learners and support an accurate understanding of each subject.
Topic Selection and Learning Goals
Each lesson should address a clear question or learning objective. We prioritize foundational concepts, commonly confused ideas, and processes that benefit from a diagram, example, or explanation in stages.
Search trends and reader questions can help identify useful topics, but they do not determine scientific conclusions. Titles should describe what a page actually explains. We avoid exaggerated promises, unnecessary repetition, and articles that add little beyond material already covered.
Content length and format depend on the learning task. A short comparison may be sufficient for one question, while a complex process may require several connected lessons.
Sources and Scientific Accuracy
Explanations should be grounded in credible, relevant sources. These may include established textbooks, university teaching resources, scientific organizations, review articles, and original research where appropriate.
Sources must support the particular claims for which they are cited. A recent publication is not automatically more suitable than an established reference, and a single study should not be presented as settled scientific agreement.
We distinguish accepted explanations from emerging findings, competing interpretations, and unresolved questions. When sources differ, we examine whether the difference reflects context, assumptions, terminology, or genuine uncertainty.
Quantitative examples should identify their units, conditions, and basis of calculation. Simplified models should explain important limitations that could otherwise lead readers to an incorrect conclusion.
Writing, Review, and Authorship
Our development process should include a clear brief, source checking, drafting, and editorial review before publication. Review should consider factual accuracy, logical sequence, terminology, examples, visual labels, and consistency between the text and supporting materials.
Authorship and review information must reflect actual contributions. We do not invent credentials, contributor profiles, institutional relationships, or review procedures.
Editorial checking is different from independent specialist review or scholarly peer review. A page may describe specialist review only when that review has taken place, and any named reviewer must have participated in the stated role.
If a topic exceeds the available expertise, the appropriate response is to obtain suitable review, narrow the scope, or postpone publication.
Diagrams, Animations, and Learning Activities
Visual materials should clarify scientific relationships. Labels, arrows, colors, scales, and captions must be consistent with the explanation they support. When a visual is schematic, uses altered proportions, or leaves out intermediate steps, that simplification should be clear where it affects understanding.
Illustrations and other media must have appropriate permission or licensing for their use, with attribution where required. Historical availability on the domain does not establish permission to reuse an earlier work.
Where quizzes or interactive tools are included, answers and explanations must be checked. Models should state relevant assumptions, units, and limits. Activities should reinforce a learning goal and provide useful feedback.
Accessibility is part of editorial quality. Meaningful text alternatives, readable labels, and explanations that remain useful without animation help more readers use the material.
AI and Automated Assistance
AI and automated tools may assist with planning, language editing, or other production tasks. Human editorial responsibility remains with 1Lecture.
Generated text, citations, diagrams, calculations, and answer keys require verification before use. AI output is not a scientific source or evidence that a lesson has received expert review.
Substantial AI involvement should be disclosed where it affects how readers understand the creation or reliability of the material. Synthetic visuals must meet the same accuracy and labeling standards as other illustrations.
Independence and Commercial Relationships
Editorial conclusions must be supported by evidence. Advertising, sponsorship, affiliate arrangements, or other commercial interests must not determine scientific explanations or prevent necessary corrections.
When a commercial relationship is relevant to particular content, it should be disclosed clearly. Paid promotional material must be distinguishable from educational editorial content.
Citing an organization or linking to its resources does not imply affiliation, endorsement, or approval of 1Lecture.
Updates, Corrections, and Reader Feedback
We review content when new evidence, reader feedback, broken resources, or identified errors indicate that a change is needed. Dates should reflect genuine publication or substantive revision.
Material errors should be corrected with an appropriate explanation of the change. Minor spelling and formatting fixes may be made without a separate notice. Content with a significant unresolved accuracy problem may be restricted or removed while it is assessed.
Readers are welcome to report problems with a page URL, the statement or visual concerned, and supporting evidence where available. Reports are considered on their substance.
This policy may be revised as the project develops. Its purpose remains consistent: clear learning materials, honest attribution, and accountable editorial decisions.
