During the early 1900’s there were two psychologist that stood out from all the others, Lev Vygotsky and Jean Piaget. Vygotsky is a part of the foundation for study of cognitive development. Born in end of 1869 and died in 1934 he was the leader of developmental psychology, education, and child development in his short thirty-five years. Moreover, Jean Piaget was born in 1896 and died in 1980 during those eighty-four years he made drastic leaps in psychology and childrens’ development. Even…

The Maya were often misinterpreted as uncivilized people that practiced human sacrifice, bloody rituals, and war. In contrast to European explorers, modern historians see the Maya quite differently in terms of sophistication. Located in Mexico, Belize, Central America, El Salvador, Honduras and Guatemala. The majority of their surroundings was made up of volcanic mountains, scrub plains, and tropical rain forests. This ancient Mesoamerican world lasted for more than 2000 years, and was split…

addition, even if they complain, they are excluded from the option of taking a harder class because of the English level they can handle. The argument is unfair for those who excel in mathematical and scientific ability but lack of English proficiency. Math and science languages are universal. Most elements in the periodic table are written and pronounced almost in the same grammar form, for example the element Hydrogen, which in Spanish is “Hidrógeno” or Sodium whose translation in Spanish…

intended recipient. While cryptography is the science of securing data, cryptanalysis is the science of analyzing and breaking secure communication. Classical cryptanalysis involves an interesting combination of analytical reasoning, application of mathematical tools, pattern finding, patience, determination, and luck. Cryptanalysts are also called attackers…

would increase. We want to define a property that describes a material's ability to transmit electrical current that is independent of the geometrical factors. The quantity that is used is called resistivity and is usually indicated by the Greek symbol rho*, **. In the case of the wire, resistivity is defined as the resistance in the wire, multiplied by the cross-sectional area of the wire, divided by the length of the wire. The units associated with resistivity are thus ohm.m (ohm -…

Rebecca Chua 10 Honors Summer Assignment: The Glass Castle by Jeannette Walls  “Like build the Glass Castle. All of Dad’s engineering skills and mathematical genius were coming together in one special project: a great big house he was going to build for us in the desert. It would have a glass ceiling and thick glass walls and even a glass staircase… All we had to do was find gold, Dad said, and we were on the verge of that. Once he finished the Prospector and we struck it rich, he’d start…

A savant is a person who incredibly excels in a particular area, such as music or math. A person who has autism yet can play a Beethoven sonata after hearing it just once, or can do complex mathematical equations, or tell you whether December 3, 1956, fell on a Tuesday or Wednesday (Whitmer, 2013). Savants may be mentally retarded but they have what is known as a very strong, specific talent (Whitmer, 2013). Savants may also have the ability to…

first introduced by Ted Codd of IBM Research in 1970 in a classic research publication "System R4 Relational." (Codd 1970), and attracted immediate attention due to its simplicity, practicality, and mathematical foundation. The model uses the concept of a mathematical relation—which looks somewhat like a table of values—as its basic building block, and has its theoretical basis in set theory and first-order predicate logic. This…

setting (Raver, 2009). As a special education teacher, Mr. Harris has over twenty years experience in the field of education with the Pittsburgh Public school district. Mr. Harris’ learning support classroom is extremely small. The classroom has two tables each with four chairs arranged around it, a large cabinet,…

Humans have been painting and creating art for thousands of years. It first began in prehistoric times, when symbols were painted in caves as a way of communication, and has evolved into modern art. Throughout the centuries art has been widely influenced by the trends and events occurring in society. The rediscovery of ancient art and literature, study of anatomy, and the Protestant Reformation, shaped the art of the Renaissance. Romanticism was a reaction to the French aristocracy and their…
