Students explain Spearman's G-Factor and how Thurstone's and Gardner's theories challenge or extend it.

Students compare Sternberg's analytical, creative and practical intelligences to other intelligence models.

Students describe the historical origin of IQ testing, from Binet and Simon's mental-age test to Stern's IQ formula.

Students identify the five components of creativity and distinguish emotional intelligence from creative intelligence.

Assign the linked video before the worksheet, since every question is written to be answered directly from the episode.

Use the editable Word file to shorten or adapt the 15 questions for a shorter class period, or assign the ready-made PDF as-is.

The included answer key allows for quick grading or immediate feedback once students finish.

Works for whole-class viewing with pause-and-discuss, or as an independent or substitute-plan assignment, since the questions are self-contained.

Video-based note extraction — students record specific concepts (G-Factor, multiple intelligences, IQ) while watching the linked episode.

Comparative analysis — students explain how Thurstone's and Gardner's theories challenge Spearman's single-factor model of intelligence.

Historical reasoning — students trace the development of intelligence testing from Binet and Simon's original purpose through Stern's IQ formula.

Conceptual distinction — students differentiate emotional intelligence from creative intelligence and describe how each is measured.
