Students in primary classes have a lot of alternate conceptions in many topics…

Concept: Alternate (or “naive”) conceptions are informal beliefs a learner builds about natural phenomena from everyday experience, distinct from the scientifically accepted idea taught in school. Constructivist learning theory holds that children construct such informal ideas continuously from every context they interact with, not from classroom teaching alone.

Application: Applying this to primary-level topics such as living/non-living, the water cycle, and plants, each of the four listed contexts independently feeds informal ideas that can diverge from the accepted concept:

• Family and community: everyday talk, folk beliefs, and cultural explanations shape a child's earliest informal picture of these topics.

• Textbooks and other books: simplified wording, diagrams, or analogies used to make a topic accessible can themselves plant an inaccurate mental model.

• Teachers: oversimplified explanations or everyday analogies used while teaching can unintentionally pass on an inaccurate idea alongside the intended one.

• Stories and poems: personifying natural objects or exaggerating their behaviour for narrative effect leaves children with a picture that does not match the scientific one.

Because all four channels are independently documented sources of such conceptions, the combination that captures every source is family and community, textbooks and other books, teachers, and stories and poems together.

Cross-check: Checking each narrower combination confirms that it leaves out at least one of these channels:

• Family and community, textbooks and other books, and stories and poems: omits teachers, incorrectly treating classroom explanations as immune to producing alternate conceptions.

• Only family and community: ignores the separately documented role of textbooks, teachers, and stories and poems.

• Family and community and textbooks and other books: leaves out teachers and stories and poems, though both are independently recognised channels.

Since every one of the four listed sources genuinely contributes, the complete combination — family and community, textbooks and other books, teachers, and stories and poems — is correct.
