HP-48SX Scientific Expandable Calculator History The HP-48SX Scientific Expandable calculator was manufactured by Hewlett Packard and the copyright is dated 1989. At the time of release, the HP-48 series was the most advanced line of scientific calculators available to those in the technical fields. I purchased the calculator in 1991 through a high school mathematics program. It has been used extensively since then for virtually every class I have taken. So far, the calculator has never malfunctioned
introduced the HP-35, the world’s first scientific pocket calculator at a cost of $395 (Hewlett-Packard, 2007). As advances in technology increase so has its accessibility. Currently, a scientific calculator will cost about $12. Additionally, anyone with internet access also has access not only to free scientific calculators but graphing calculators as well. Let’s not forget iPhones and all of the calculator apps that are ready for download. Needless to say calculators are readily available to students
For this field assignment, I chose to observe a seventh grade self-contained math class at William A Morris I.S 61 on Staten Island. I am currently a substitute teacher at the school and has worked at this school for approximately two years. For the purpose of this observations, I worked with Mr. Karl Knutsen, a 6th and 7th grade math, special education and technology supervisor at the school. Mr. Knutsen has been a teacher for seven years and has worked in I.S 61 for five. He currently teaches all
little progress in the calculating devices. Most of the calculations are performed by “teams of human computers equipped with desk-top calculating machines”. (3) In 1939, the World War two started. Different than the ancient wars, World War Two was a scientific war
education, I’m going to focus on devices that are designed for use in the elementary level education. The devices I will focus on are Talking Calculator, The Basic Ten Blocks, and Tangrams. These tools have become most widely used primarily because of cost effectiveness, and easy assessability of the products. • Talking Calculator – is a basic calculator that has a built in speech synthesizer that will read the numbers, symbols, and operation keys out loud during use. The auditory feedback helps
Many researchers have noted that teachers are central to the intelligent use of calculators in schools, and thus will need well-designed support to ensure that calculators are appropriately used. Some of this support will take the form of professional development of various kinds, but it will also be necessary for materials to be developed to suit the needs of teachers in classrooms. As suggested by Kissane (2003), teachers need to be confident users of technology themselves before they will effectively
and “Is Google Making Us Stupid”, by Nicholas Carr, the common theme is the use of technology and how it has changed the world’s technological advances in the world. Technology has made an imperative impact on enhancing medicine and developing scientific theories as well as in increase effectiveness in many other fields like education and transportation. You cannot take technology for granted and I would like to argue that through the uses of technology, there is such a thing as too much of a good
History of the PC “If one thinks about it, it is truly remarkable how far the technology has advanced since the first digital computer was introduced in 1946. The ENIAC (Electronic Numerical Integrator and Calculator) was designed and built at the University of Pennsylvania. It weighed 30-tons and took up 1500 square feet of floor space. The first computer developed in Europe was the EDSAC (Electronic Delay-Storage Automatic Computer). This machine was built at Cambridge University in 1949.
issue of calculators weakens very important math skills early in the developmental period in their education. So, the intriguing question becomes: Does using a calculator help or harm our students? We now investigate studies reported in the literature which have delved into these questions with very convincing arguments. Before 1975 calculators in the classroom were not common, as they were rare and expensive (Banks, 2011, p.7). However, during the 1980’s some states were providing calculators to students
accounting profession began to take on a whole new look. Computers and accounting software has changed the industry completely. With programs such as Microsoft Excel an accountant now had an electronic spreadsheet. The need for adding machines, calculators, ledgers and pencils was eliminated. The job became less tedious with less of a margin for error. The core training for accountants which included the basic accounting, auditing and tax preparation was a thing of the past. With use of the computer
scales. This slide ruler could do such calculations as division, multiplication, roots, and logarithms. Soon after came some more advanced computers. In 1642 came Blaise Pascal's computer, the Pascaline. It was considered to be the first automatic calculator. It consisted of gears and interlocking cogs. It was so that you entered the numbers with dials. It was originally made for his father, a tax collector.2 Then he went on to build 50 more of these Pascaline's, but clerks would not uses them.3 They
many aspects of Psychology. Let us start with the basic computer which is the calculator. We Psychology major’s use the calculator all the time, particularly in the class of test and measurements, are shown how to administer a test to students, adults, etc… Then shown to calculate the different results and the different formulas we use and what the formulas mean. We also use the calculator, especially a calculator with graphing functions, to make graphs and to see what the math formula actually
is achieved differs greatly. Vietnam, a small country with a large population, has to make do with the lack of technology. It stresses hard work rather than the use of machines. Children are encouraged to do math mentally rather than depend on calculators. As a result, the Vietnamese people do not consider it a sacrifice that they should lead a hard life. Also, their education emphasizes morality rather than independent thinking. Therefore, most Vietnamese children would never think of leaving their
Abstract My classroom management philosophy is a constant work in progress, but based off of personal experiences and major management theorists I have developed a basic philosophy to guide me through student teaching and the early years as a teacher. The core principles of my philosophy are rooted in establishing a classroom community and mutual respect between students and the teacher. The following essay outlines the theorists that have impacted my philosophy as well as ways I plan to
Math Research Paper Since the 1980’s calculator use in the classroom has been a huge controversy between educators (Golden, 2000). It is becoming increasingly common to use calculators in the classroom on a regular basis. Some states allow students to use calculators on standardized tests and as part of the regular curriculum (Dion, 2001). Because we live in such a technologically changing world, hand held calculators have been far surpassed and can be purchased for as low as $4.00 each. This
tool used in education. “During the past three decades, computers have become the most talked about, written about, and ubiquitous machines ever to be imposed upon mankind.”( Rockart, 1995, p. 55). The ENIAC (Electronic Numerical Integrator and Calculator) is said to be the first computer. It was a “huge machine having thousands of vacuum tubes and consuming vast amounts of electrical power.” ( Merrill, 1996, p.54). By the early 1970’s, the regular computer was invented. Around the same time, something
between the denominators rather than the ‘fractions’. So I am looking for a formula that will explain the sequence: 2, 6, 12, 20, 30. First of all though I decided to extend the sequence in order to have a broader range to work with. I used a calculator to work out the following denominators finding the difference between [IMAGE] and [IMAGE], [IMAGE] and [IMAGE] all the way up to [IMAGE] I set the differences out in a table to try to find the pattern: nth number 1 2 3 4 5
Over the past few years technology has taken on a whole new meaning. We have moved from the days of chalkboards, to whiteboards, to interactive whiteboards. Our students seem to be more computer savvy than their teachers. Home telephones are starting to become a thing of the past, and cell phones have turned into mini-computers. Technological geniuses have even tried to eliminate books by creating electronic books, for example the Kindle and Nook. It has become pretty evident that being technologically
results, as there may be more or less resistance between types of wire. To study the resistance or wire we experimented on changing the length of nichrome wire. We measured the volts and amps over 1 metre; I worked out the resistance using my calculator. We carried out this experiment 5 times to make the results fair. We let the wire cool down a bit between doing the experiments, as its temperature did tend to increase as we got to the end of each experiment. Analysis We took a set of
anyone's PC; they can delete English papers before they are printed; they can hack into a webcam to take pictures; they can hack into phones to listen to conversations; they can hack into the traffic light to cause accidents; they can hack into calculators to make students fail a math test; they can hack into watches to make people late. Thus, I must offer a modest proposal to immediately destroy each and every computer. Computers have managed to infiltrate most of the modern lifestyle, but by removing
