A free, world-class education for anyone, anywhere: this is the goal of the Khan Academy, a passion project that grew from an ex-engineer and hedge funder's online tutoring sessions with his niece, who was struggling with algebra, into a worldwide phenomenon. Today millions of students, parents, and teachers use the Khan Academy's free videos and software, which have expanded to encompass nearly every conceivable subject; and Academy techniques are being employed with exciting results in a growing number of classrooms around the globe. Like many innovators, Khan rethinks existing assumptions and imagines what education could be if freed from them. And his core idea-liberating teachers from lecturing and state-mandated calendars and opening up class time for truly human interaction-has become his life's passion. Schools seek his advice about connecting to students in a digital age, and people of all ages and backgrounds flock to the site to utilize this fresh approach to learning. In The One World Schoolhouse, Khan presents his radical vision for the future of education, as well as his own remarkable story, for the first time. In these pages, you will discover, among other things: How both students and teachers are being bound by a broken top-down model invented in Prussia two centuries ago Why technology will make classrooms more human and teachers more important How and why we can afford to pay educators the same as other professionals/DIV How we can bring creativity and true human interactivity back to learning/DIV Why we should be very optimistic about the future of learning. Parents and politicians routinely bemoan the state of our education system. Statistics suggest we've fallen behind the rest of the world in literacy, math, and sciences. With a shrewd reading of history, Khan explains how this crisis presented itself, and why a return to "mastery learning," abandoned in the twentieth century and ingeniously revived by tools like the Khan Academy, could offer the best opportunity to level the playing field, and to give all of our children a world-class education now. More than just a solution, The One World Schoolhouse serves as a call for free, universal, global education, and an explanation of how Khan's simple yet revolutionary thinking can help achieve this inspiring goal.
An overwhelmingly Arab-centric perspective dominates the West’s understanding of Islam and leads to a view of this religion as exclusively Middle Eastern and monolithic. Teena Purohit presses for a reorientation that would conceptualize Islam instead as a heterogeneous religion that has found a variety of expressions in local contexts throughout history. The story she tells of an Ismaili community in colonial India illustrates how much more complex Muslim identity is, and always has been, than the media would have us believe. The Aga Khan Case focuses on a nineteenth-century court case in Bombay that influenced how religious identity was defined in India and subsequently the British Empire. The case arose when a group of Indians known as the Khojas refused to pay tithes to the Aga Khan, a Persian nobleman and hereditary spiritual leader of the Ismailis. The Khojas abided by both Hindu and Muslim customs and did not identify with a single religion prior to the court’s ruling in 1866, when the judge declared them to be converts to Ismaili Islam beholden to the Aga Khan. In her analysis of the ginans, the religious texts of the Khojas that formed the basis of the judge’s decision, Purohit reveals that the religious practices they describe are not derivations of a Middle Eastern Islam but manifestations of a local vernacular one. Purohit suggests that only when we understand Islam as inseparable from the specific cultural milieus in which it flourishes do we fully grasp the meaning of this global religion.

How colonial categories of race and religion together created identities and hierarchies that today are vehicles for multicultural nationalism and social critique in the Caribbean and its diasporas. When the British Empire abolished slavery, Caribbean sugar plantation owners faced a labor shortage. To solve the problem, they imported indentured ÒcoolieÓ laborers, Hindus and a minority Muslim population from the Indian subcontinent. Indentureship continued from 1838 until its official end in 1917. The Deepest Dye begins on post-emancipation plantations in the West IndiesÑwhere Europeans, Indians, and Africans intermingled for work and worshipÑand ranges to present-day England, North America, and Trinidad, where colonial-era legacies endure in identities and hierarchies that still shape the post-independence Caribbean and its contemporary diasporas. Aisha Khan focuses on the contested religious practices of obeah and Hosay, which are racialized as ÒAfricanÓ and ÒIndianÓ despite the diversity of their participants. Obeah, a catch-all Caribbean term for sub-Saharan healing and divination traditions, was associated in colonial society with magic, slave insurrection, and fraud. This led to anti-obeah laws, some of which still remain in place. Hosay developed in the West Indies from Indian commemorations of the Islamic mourning ritual of Muharram. Although it received certain legal protections, HosayÕs mass gatherings, processions, and mock battles provoked fears of economic disruption and labor unrest that lead to criminalization by colonial powers. The proper observance of Hosay was debated among some historical Muslim communities and continues to be debated now. In a nuanced study of these two practices, Aisha Khan sheds light on power dynamics through religious and racial identities formed in the context of colonialism in the Atlantic world, and shows how today these identities reiterate inequalities as well as reinforce demands for justice and recognition.
How ornamentation enables a direct and immediate encounter between viewers and art objects Based on universal motifs, ornamentation occurs in many artistic traditions, though it reaches its most expressive, tangible, and unique form in the art of the Islamic world. The Mediation of Ornament shares a veteran art historian’s love for the sheer sensuality of Islamic ornamentation, but also uses this art to show how ornament serves as a consistent intermediary between viewers and artistic works from all cultures and periods. Oleg Grabar analyzes early and medieval Islamic objects, ranging from frontispieces in Yemen to tilework in the Alhambra, and compares them to Western examples, treating all pieces as testimony of the work, life, thought, and emotion experienced in one society. The Mediation of Ornament is essential reading for admirers of Islamic art and anyone interested in the ways of perceiving and understanding the arts more broadly.
