A quality education for children

Children are entitled to a quality education such like Adding fractions in basic algebra. This definition allows an understanding of education as a complex system in a political, cultural and economic integrated. It is important to note, to keep the systemic nature of education, however, these dimensions are interrelated and influence each other in ways that are sometimes unpredictable. Find education such as Linear programming and line plot online.

In all aspects of the school and its surrounding community education, the rights of the whole child and all children, development, protection, survival and participation in the center. This means that the emphasis on learning, which strengthens the ability of children to act progressively on their own through the acquisition of appropriate options, useful skills and knowledge relevant and designed for children and helps to create for themselves and others, healthy interaction, places of safety and security. Basic education about math like 4th grade math and 5th grade math are available on the internet. The quality of education includes:

-A healthy environment, gender equality, protection facilities and adequate security and resources;

-Learners, well fed, healthy and ready to learn and to participate in learning and supported by their communities and families;

-Process to facilitate the training of teachers, child-centered teaching approaches used in classrooms and well-managed schools and assessment skill, learning and reduce disparities.

-The content that is in the relevant documents and programs for the acquisition of basic skills, particularly in the areas of life skills, numeracy and literacy and knowledge in areas such as gender, HIV / AIDS, health, nutrition and expression of peace.

-These results include the skills and attitudes, knowledge (such like Solving equations and as Algebra solver), and are on the national goals for education and positive participation in the combined company.

Basic Differences Between AM and FM

We need to mention a couple of other things before we leave the discussion of how radio works.  We’ve talked about AM and FM radio, but we haven’t explained the real difference.

In fact, there is a lot of difference — and not just a difference in the station numbers on your radio dial.

The first type of radio service — the one we’ve been talking about in the last couple of modules — was AM radio.

The term modulation refers to how sound is encoded on a radio wave called a carrier wave; or, more accurately, how the sound affects the carrier wave so that the original sound can later be detected by a radio receiver.

In the top-left of this drawing the RF energy (carrier wave) is not modulated by any sound.  There would be silence on your radio receiver.

Sound transmitted by an AM radio station affects the carrier wave by changing the amplitude (height) of the carrier wave, as shown on the left.

Unfortunately, this type of modulation is subject to static interference from such things as household appliances — and especially from lightening storms.

AM also limits the loud-to-soft range of sounds that can be reproduced (called dynamic range) and the high-to-low sound frequency range (called frequency response, to be explained below).

FM radio, which came along in the 1930s, uses a different approach than AM. It’s virtually immune to any type of external interference, it has a greater dynamic range, and it can handle sounds of higher and lower frequencies. This is why music, with its much greater frequency range than the human voice, sounds better on FM radio.

Note on the left that when the carrier wave of FM radio is modulated with sound that the distance between the waves, or the frequency of the carrier wave, changes.

Thus, AM radio works by changing the amplitude of the carrier wave and FM radio works by changing the frequency of the carrier wave.

Frequency Response

Frequency relates to the basic pitch of a sound — how high or low it is. A frequency of 20 Hz would sound like an extremely low-pitched note on a pipe organ — almost a rumble.

At the other end of the scale, 20,000 Hz would be the highest pitched sound that can be imagined, even higher than the highest note on a violin or piccolo.

As we’ve noted, frequency is measured in Hertz (Hz) or cycles per second (CPS). A person with exceptionally good hearing will be able to hear sounds from 20-20,000 Hz.

Since both ends of the 20-20,000Hz range represent rather extreme limits, the more common range used for FM radio and TV is from 50 to 15,000 Hz. (A typical AM radio signal does not cover this entire range.)

Although the 50-15,000 Hz doesn’t quite cover the full range that can be heard by people with good hearing, it covers almost all naturally occurring sounds.  Note in the drawing above that the ear does not hear all frequencies of sound at the same loudness, but a good microphone does.

The sound level or amplitude of sound in radio and TV stations is monitored and adjusted with the help of a volume units meter (VU meter) meter. One model is shown on the left.  Audio levels must be carefully controlled in broadcasting to keep noise and distortion from reducing the quality of sound.

Radio, a potential medium for education

While admiring the growth of radio production and broadcast technology, Madhu Ranjan feels that it still continues to be an under-utilized technology in education. According to her, radio has enormous potential to improve distance education systems especially when integrated with other technologies such as television, mobile telephones, and the Internet.

Soon after its invention in the late 1890s, radio, due to its information and

entertainment value, vast reach, and immediacy, became the most popular means of mass communication around the world.

With the arrival of television, the birth of satellite broadcasting technology, and later the Internet, radio’s listener base began to erode and its importance diminished.  In the 1970s, however, radio (FM band) once again gained popularity, especially among young listeners.

Today, improved broadcasting quality, more innovative and entertaining content, and new technological developments in fields such as digital and satellite radio have made radio a resurgent medium, extremely popular in the fields of advertising and entertainment. Affordability, portability, and access indoors and outdoors give radio a clear edge over other media. Additionally, radio is increasingly becoming a more dynamic medium, as it is integrated into other new technologies such as television, mobile telephones, and the Internet.

This has opened up new opportunities for a variety of forms of delivery and access. For example, portable, low-cost FM transmitting stations have been developed and digital radio systems that transmit via satellite are being set up in many parts of the world. Internet streaming audio software technology now allows a global audience to listen to news from a distant country. In addition, the development of wind-up and solar radios utilizing inexpensive power sources allows radio to can cut across geographic, economic, and cultural boundaries.

However, radio still continues to be an under-utilized technology in education. This is somewhat surprising because, for a learner, radio is a simple, user friendly, accessible, and a well-established medium. From an educational provider’s point of view it is easy and inexpensive to set up, produce, and broadcast programs. Most nations currently have the engineering skills and broadcasting talent to apply this technology to education.

Today, many schools, colleges, universities, and other organizations use distance education systems. While developing a distance education system, factors such as cost effectiveness, efficiency, and the availability of appropriate communication technologies, as well as access and equity issues, particularly those related to gender, language, social status, and religion, are the most important considerations.

Other factors to consider relate to how distance learners can best use their higher order thinking skills and how they can cope with the limitations of time, age, gender, and language. Radio is able to address these issues while reaching a diverse group of learners and can be valuable in many different distance learning environments including schools, colleges and universities, businesses, and public sector organizations.

For distance education providers, radio is a cheaper alternative to other communication technology mediums. Producing interactive radio programs in distance education requires only low-priced equipment compared with other cutting-edge technologies. Educational institutions do not need to spend much money for establishing interactive radio studios in their organizations.

Learners are equally fortunate, because they do not have to buy or rent the costly and complex equipment required by TV and the Internet. There are no boundaries to broadcasting educational programs with interactive radio throughout the world and as long as learners have access to a very low-cost radio, they can listen to programs wherever they are; riding in their cars, traveling by bus or train, or working at home.

Moreover, interactive distance educational programs can be recorded for learners via inexpensive equipment, such as cassettes, CDs, or MP3 players. Educational radio helps provide equal access to knowledge for everyone by breaking digital walls around the world.

Interactive radio programs allow people with disabilities (with the exception of the hearing-impaired) to hear the voices of instructors, classmates, and experts, enhancing their ability to learn. While listening to interactive radio programs, learners have more time to construct knowledge.

Community radio is also an immensely powerful technology for the delivery of information with enormous global potential.  It is particularly powerful in providing access to information for marginalized populations, including women, minorities, and the poor, who often do not have access to more cutting edge technology. Radio can expand opportunities for the intended beneficiaries of development to participate in the in the development agenda, which can appropriately and adequately respond to their needs and aspirations.

Currently, the benefits of radio as a learning medium are overlooked. Conventional wisdom assumes that high-cost communication media ensure better interactive distance learning. Radio, however, when incorporated with interactive learning approaches, has enormous potential to improve distance education systems. In a very imaginatively designed program – funded by USAID and implemented by EDC – that makes the process of teaching-learning interesting and meaningful, radio lessons that introduce substantial interaction among students and teachers are improving classroom interaction in close to 300,000 government schools reaching over 25 million primary school students across several states in India.

Many interventions around the world are using radio innovatively; successfully enhancing the quality of teaching learning in traditional classroom settings, imparting health messages to communities; and providing useful information on agriculture to farmers.  Although it is not currently being exploited to its full potential, radio is a medium with tremendous potential, particularly for educational purposes.

Interactive radio for education

Interactive Radio Instruction (IRI) is an instructional tool designed to deliver active learning by radio. It delivers daily 30-minute radio broadcasts that promote active learning and are designed to improve educational quality and teaching practices in schools and to deliver a complete basic education to learners not in school.

Data gathered between 1975 and 2000 demonstrated that Interactive Radio Instruction (IRI) had improved learning outcomes in conventional classrooms by between 10% and 20% when compared with control classrooms not using IRI.

IRI is an effective delivery mechanism for in-service professional development, as teachers are able to actively employ improved instructional techniques in the classroom while undergoing radio-based training. Teachers not only demonstrated a better understanding of pedagogical concepts emphasised by broadcasts, but more frequently utilised active learning and student-centered techniques in lessons independent of radio guidance.

The manual looks into the aspects of learning outcomes by subject, on the impact of IRI on pre-primary and early childhood learning outcomes, radio-based in-service professional development for primary school teachers.

The document has been broadly organised in the following sections:

- Student learning outcomes by subject area

- Student learning outcomes in early childhood education

- Teacher professional development observation outcomes

- Student learning outcomes with marginalised populations

Citing examples from various countries the manual highlights the impact of IRI on the learning outcomes of four key marginalised groups: girls, orphans and vulnerable children, learners in fragile states, and those in rural areas.

A review of the learning outcomes of various countries brought to light some of the successful, and not-so-successful, IRI experiences. Key findings of the research revealed that without adequate information on student attendance, quality of teacher training and consistency of teacher attendance, it was impossible to draw definitive conclusions regarding the marginal impact of IRI on student learning.Students not only can create NFL, MLB, NBA & NCAA emblems but any of their favorite team easily.
