Banning AI in projects sends the wrong message. Instead, guide students on approved tools and specific project stages where AI is acceptable—like brainstorming and fact-checking—while prohibiting it for final reflections. #AIinEducation #EdTech #StudentGuidance

Put August 12 in your phone now. Genuinely. Before sunrise, six planets spread across the sky. Afternoon, the eclipse. After dark, the Perseids Meteor shower. Four events on one day, NASA says, and the new moon that same date keeps the sky dark enough to actually see the meteors. You don't need a telescope for most of it. A field, a coat, and twenty minutes for your eyes to adjust.

The 2026 AP World History: Modern Exam scores: 5: 14%; 4: 36%; 3: 16%; 2: 26%; 1: 8% The 2026 AP World History: Modern exam was taken by ~443,000 students, roughly 3% of the U.S. high school population. AP World History: Modern — Multiple-Choice Questions (MCQs) AP World History: Modern students performed well across all units and thematic learning objectives. A few notable patterns stood out: • Students showed their strongest MCQ performance on questions focused on Units 3 and 4 — Land-Based Empires and Transoceanic Interconnections (1450–1750 CE). Students earning AP 3s typically answered at least 70% of these questions correctly, students earning AP 4s: ~85% right, and students earning AP 5s generally answered 100% of these questions correctly. These results indicate that AP World History students with scores of 3+ have developed solid understanding of the early modern period and the forces that shaped it. • The most challenging MCQ content was for Units 7 and 8 — Global Conflict and the Cold War and Decolonization (1900–present). Nonetheless, students earning scores of 3+ were able to answer most or all of these questions correctly, while students receiving scores of 1 and 2 were not. AP World History: Modern — Exam Design and Rigor The AP World History: Modern Exam Development Committee — composed of university historians and experienced AP teachers — built a 2026 free-response section that I find genuinely impressive in its breadth and intellectual ambition. It’s also important to note that students do all of this writing within a fixed time limit in a proctored room on an AI-blocked platform. Here's a link to this year's free-response questions: https://t.co/WCZZEgvao2 Since AP scores are reported on a 5-point scale, the free-response questions deliberately include some very difficult points to differentiate AP 5s from AP 4s, points of varying difficulty to differentiate AP 4s, 3s, and 2s, and more foundational points to separate AP 2s from AP 1s. AP World History: Modern — Short Answer Questions (SAQs) Each AP exam has multiple versions for different time zones. The commentary below focusses on the version taken by the majority of AP World History: Modern students: SAQ 1, the Mansa Musa and Trans-Saharan Trade question, focused on a secondary source, asked students to identify historical causation (Mansa Musa’s motivations), deploy outside evidence to extend a scholarly claim, and explain the impacts of long-distance trade routes on particular societies – a robust and challenging task that primarily differentiated AP students achieving scores of 4 and 5, who could typically answer all parts of the question thoroughly, and students earning scores of 3, who did not typically earn all points possible on this question. SAQ 2, which asked students to analyze a 1549 primary source (a letter by Spanish Jesuit missionary Francis Xavier written from India) and SAQ 3 (describing and explaining Indian Ocean trade networks) were each less challenging than SAQ 1, serving well to differentiate between students receiving AP scores of 2, who could usually answer one part of these questions correctly, and students receiving AP scores of 3+, who earned most or all points possible. SAQ 4 (describing and explaining global trade from 1750-1914), was far and away the most challenging SAQ; in fact, it was the lowest-scoring of all the FRQs. Students receiving 1s and 2s were generally unable to earn any points on this question, which instead differentiated between performance at AP 3, 4, and 5 levels. AP World History: Modern — Document-Based Question (DBQ) This question asked students to evaluate the extent to which twentieth-century military conflicts changed the role of women in society, by analyzing seven primary documents from China, the British Empire, Tsarist Russia, France, Mexico, Kenya, and the Soviet Union. The DBQ is always one of the most impressive tasks across all AP subjects, and this year’s was no exception, given the intellectual sophistication this question demanded — students had to hold multiple imperial and national contexts in view simultaneously and synthesize across them to write a compelling historical argument. The DBQ serves well to differentiate students who qualify for college credit from those who don’t, as students receiving an AP 3+ score earned most of these points, whereas students earning 1s and 2s did not. Crafting a historical claim / thesis: 86% of students earned the thesis point, a differentiator between AP scores of 1 and 2, as students receiving a 2 consistently earned this point, whereas students receiving a 1 did not. Use of evidence from the primary source documents: this skill also differentiated between AP scores of 1 and 2, as students receiving a 2 were able to extract at least some historical evidence from the documents, whereas students receiving a 1 were not. Students receiving a 3 or higher typically earned full points for this skill. Outside evidence and contextualization. These two historical thinking skills differentiated AP scores of 3 from AP scores of 4 and 5, as students achieving AP 4s and 5s were generally able 1) to summon and integrate outside evidence into this source-based essay, and 2) to situate their argument within a broader historical context. Students earning AP 3s demonstrated these skills less consistently than students earning AP 4s and 5s. Sourcing. Similarly, students achieving AP 4s more consistently earned the sourcing point — requiring them to explain how the point of view, purpose, historical situation, or audience of two or more of the documents is relevant to their argument — than students earning AP 3s. Complexity of analysis and reasoning. 22% of students earned the complex understanding point, the most demanding point on the DBQ, a differentiator between students achieving AP 5s, who are consistently earning this point, and students earning AP 4s, who are much less consistently earning this point within the intensity of timed, proctored essay writing. AP World History: Modern — Long Essay Question (LEQ) Students choose one of three long essay prompts. Here’s a summary of their performance on each: • LEQ 2, in which students evaluated the relationship between military conflicts and state building in Afro-Eurasia (1200–1600), proved more challenging for students than the other two LEQ topics. 25% of students achieved all or all but one of the total points possible, but the overall difficulty of this essay was such that students receiving 1s did not earn any points on it. • LEQ 3, in which students evaluated migrations from 1600-1900 and their relationship to social and cultural changes, was somewhat less difficult for students than LEQ 2, as students receiving 1s were typically able to earn several points related to their thesis or evidence they cited. 25% of students achieved all or all but one of the total points possible. • LEQ 4, in which students evaluated whether peacemaking efforts in the 20th century were successful, had the highest overall scores of any of the Long Essay topics. 34% of students achieved all or all but one of the total points possible.

GPS pioneer and mathematician Gladys West has died. She was 95. Her calculations helped produce extremely accurate modeling of the Earth's shape, laying the foundation for modern global positioning system technology. West was born in rural Virginia during segregation. In 1956, she was hired as a computer programmer at a Navy base in Virginia, where she was one of only four Black employees. Her work went largely unrecognized for years, though she was later acknowledged as one of the hidden figures of the era. Despite being considered the mother of GPS, West said she still preferred using a paper map when driving.
