The Inka Empire stretched over much of the length and breadth of the South American Andes, encompassed elaborately planned cities linked by a complex network of roads and messengers, and created ...astonishing works of architecture and artistry and a compelling mythology—all without the aid of a graphic writing system. Instead, the Inkas’ records consisted of devices made of knotted and dyed strings—called khipu—on which they recorded information pertaining to the organization and history of their empire. Despite more than a century of research on these remarkable devices, the khipu remain largely undeciphered. In this benchmark book, twelve international scholars tackle the most vexed question in khipu studies: how did the Inkas record and transmit narrative records by means of knotted strings? The authors approach the problem from a variety of angles. Several essays mine Spanish colonial sources for details about the kinds of narrative encoded in the khipu. Others look at the uses to which khipu were put before and after the Conquest, as well as their current use in some contemporary Andean communities. Still others analyze the formal characteristics of khipu and seek to explain how they encode various kinds of numerical and narrative data.
Literacy ability is an individual's ability to reason, formulate, solve, and interpret mathematically to solve problems related to daily life. Executive function is a cognitive aspect that has a ...relation with mathematical literacy. One of some aspects that affects the low mathematical literacy ability is the aspect of executive function. This study aims to investigate the characteristics of mathematical literacy based on the executive function aspects of 15 years old students. A qualitative method with a descriptive approach is employed in this study. The present research applies interview guidelines, questionnaires, and students' mathematical literacy tests as the instruments. Research subjects are junior high school students in grade VIII from two different schools. The result shows that the students' executive function influences mathematical literacy ability. Students' mathematical literacy ability is not fully achieved by fulfilling all the indicators involved. Another aspect found in the research is the low critical thinking ability impacts the achievement of mathematical literacy ability indicators.
