Biology, class 10

Two curriculum generations are visible in the contents pages. Sindh and KP print the same 2006 sequence — gaseous exchange, homeostasis, coordination and control, support and movement, reproduction, inheritance, man and his environment, biotechnology, pharmacology — with Sindh numbering from 1 and KP continuing from 10, the same renumbering that distinguishes the chemistry books. Punjab and the Federal Board are on the newer scheme and reorganise around human systems: digestive, respiratory, urinary, coordination, reproduction. Two additions are unique and both are worth noting. The Federal Board alone ends with biostatistics and data handling, teaching pupils to handle evidence numerically in a way no other board's biology does. Punjab alone carries a chapter on evolution — which, set beside the study's separate finding that Sindh's Social Studies 6 offers creation and evolution as two coequal theories, shows the boards are not aligned even on whether this is a settled topic. Religion is absent throughout: every board scores 1, and Punjab returns zero religious tokens across 31,566 words. Assessment splits hard. Sindh's volume contains zero evaluation verbs and zero open prompts across 39,308 words — pure recall, the most closed book in the cell at 5 — while KP sets three of each and scores 2, the most open. Punjab sits at 4 with two evaluation prompts and none open. One oddity belongs on the record: Punjab's biology book carries martial vocabulary at 0.5 tokens per thousand words. In a book about digestion and inheritance there is no subject-matter reason for it, which is exactly the condition under which that measure becomes diagnostic.
