   3 flagged findings: Unverified verbatim-quote framing of Craik & Lockhart's 1972 levels-of-processing findings; an unverified 'nearly twice as many inferences' precise figure attributed as a direct quote to the real Chi et al. (1994) self-explanation study authors; an unverified 'three passes vs one pass' specific claim attributed as a direct quote to Roediger & Karpicke (2006). Also fixed this article's side of the Ebbinghaus forgetting-curve cross-article contradiction identified in the sibling SQ3R article.

   Before

   "Retention is not a passive consequence of comprehension. It is an active outcome that requires deliberate encoding strategies layered on top of initial understanding." -- Fergus Craik and Robert Lockhart, Journal of Verbal Learning and Verbal Behavior, 1972 [...] Ebbinghaus's forgetting curve shows that without review, 50-80% of learned material is forgotten within a week. [...] "Students who self-explain while reading generate nearly twice as many inferences about material relationships as students who read without self-explanation, and retain the material significantly better on delayed tests." -- Michelene Chi, Nicholas de Leeuw, Mei-Hung Chiu, and Christian LaVancher, Cognitive Science, 1994 [...] "The investment in active encoding strategies during initial study is always recouped through reduced re-study time. Passive reading that requires three passes to achieve what active reading achieves in one pass is not efficient, regardless of page rate." -- Henry Roediger III and Jeffrey Karpicke, Psychological Science, 2006

   After

   In this view, retention is not a passive consequence of comprehension. It is an active outcome that requires deliberate encoding strategies layered on top of initial understanding. [...] Ebbinghaus's forgetting curve shows that without review, approximately 75% of learned material is forgotten within a week. [...] Students who self-explain while reading tend to generate more inferences about material relationships than students who read without self-explanation, and tend to retain the material better on delayed tests. [...] The investment in active encoding strategies during initial study is generally recouped through reduced re-study time later. Passive reading that requires multiple passes to achieve what active reading can achieve in fewer passes is not an efficient use of study time, regardless of page rate.

   Why: Removed three unverified verbatim-quote framings incorrectly attributed as direct quotations to Craik & Lockhart (1972), Chi et al. (1994), and Roediger & Karpicke (2006), including an unverified precise 'nearly twice as many inferences' figure and an unverified 'three passes vs one pass' claim. Converted all three to plain, appropriately-hedged prose connecting the claims to the real underlying research without inventing verbatim quotations or unsupported precise figures. Also corrected this article's Ebbinghaus forgetting-curve figure from '50-80% within a week' to the verified-accurate 75%-within-a-week figure, resolving a cross-article contradiction with the sibling SQ3R article.
