Computer Programming

I learned that computer programming is an active mental endeavor. Programmers must break down complex problems into sub problems and then develop procedural instructors. According to research that programming is the only subject in the whole curriculum that succeeds in teaching learners about things as a process. There are also program that can help the learners to enhance their competencies

Guidance for using computers and computer software’s

            The guidelines give information wherein the teacher or the users can be able to become aware of those services, uses of the computer in the classroom. And on how the users should be able to correct simple problems that they will encounter.

Computer Software

            I have learned that current software presents whole units and courses of instructions and interactive systems that being introduced nowadays. I have also learned that the early software are consist with specific answers while the new software permits a variety of students with branching to appropriate levels of instruction based on the students response.

Evaluating Computer Software

            I have learned that the eight characteristics evaluated on evaluating software is that it should has a quality, directions, user interaction, data flexibility and evaluation. With these characteristics we can enjoy the learning process through computer software.

Telecommunication System and Satellite Dishes

I have learned that Telecommunication refers to information exchange between two or more locations connected by electronic media, including television, radio, and telephone. And the presentation of the reporter it stated that there are several hundreds of educational organizations have their own telecommunication system. And based on what I have learned there are about fifty percent own their system.45% base, and only 5% operate a combined based-owned system. Also I have learned that owned systems operate through television or radio broadcast system based or based-owned systems operate through telephone lines. On this new technology of instructional materials we can have more knowledge to share into our students.

Satellite Dishes

            In this topic I learned that dish is a type of parabolic antenna designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television. In which the teacher can be able to use it as material for instruction. It can also provide information to both teachers and learners. The satellite services include educational programs for the home, but this will happen only if the teacher call for it and use it when available.


            I have learned that a teleconference to be successful, presentations need to be both interesting and educational. The integration of media components such as slide, overhead transparencies, videotapes, or handouts in an audio teleconference expands a single-channel presentation into a multi-sensory channel presentation. The selection and utilization of such media should be based upon instructional principles derived from research on human perception and human learning. Attention-gaining techniques can include the use of alerting sounds, light changes, or other sudden changes in the environment, and the design of instructional materials to emphasize important concepts. The organization or patterns of a message also play an important role in the processing of information; e.g. spatial arrangement or temporal ordering of message elements can facilitate perceptual groupings and reduce processing demands. The teleconference presenter also needs to be aware of learning strategies which affect retention of content, and organize the presentation so that the content is relevant, the learner understands the structure and organization of the presentation, and interactive techniques are used to involve the learner actively in the learning process. A variety of media components can be integrated into a teleconference presentation to enhance retention of the material presented.

Teletext System

            I have learned that teletext system images provide a useful method of presenting information to the learners. In a learning situation the use of pictorial forms can offer a high-bandwidth mechanism for the transfer of information between an instructor and a student. This paper discusses some ways of providing graphic support in a computer-based learning environment and describes some approaches to the provision of authoring facilities that utilize this technique.       


            I have learned that Telewriting is an instrument in which a kind of system for transmitting handwriting and similar data in real time over voice grade telephone lines and reproducing such data at remote locations utilizes digital transmission to reduce the effects of transmission noise and signal distortion and to provide an easy means for control of remote apparatus. An ultrasonic transducer and microphone combination provides readout of the writing head position with respect to a writing surface such as a blackboard. The readout signal is converted into digital form and transmitted to the remote locations where it is reconverted to analog form. The analog signal is used to control the deflection of an ultraviolet laser which reproduces the data on a photosensitive plate while the plate is simultaneously projected by visible light. The analog signal can also control other types of utilization apparatus. So this is applicable for distance learning.


            It is an offshoot of the writing system. And I learned that it can send images from the monitor to another over the telephone wires. The sender can also transmit pictures within 8-30 seconds to another unit. This is also applicable for distant schools. The transmission system can link within a 200 mile range, so it is applicable to use in distance learning.


            It is use at home by the learners, since the older learners can work independently for secondary level. While in elementary level they are better to used in whole group instruction in the school. So the teacher can provide necessary monitoring feedback.

Video System

            In what I have learned classroom which integrates sources of video instructional materials, such as TV, CATV, VCR, video disk players, closed circuit TV, and the like, with sources of computer-based instructional materials is disclosed. Modulated video sources are converted to baseband and applied, along with baseband video sources, to a multichannel modulator or headend. The headend drives a local video network (LVN) which couples to a plurality of student workstations and to an instructor workstation. In addition a local area network (LAN) couples to the student workstations, the instructor workstation, and to a file server. Each of the instructor and student workstations includes a computer, a monitor control unit (MCU), a video display, and an audio transducer. The workstation computers couple to the LAN and the workstation MCU's couple to the LVN. A curriculum delivery system (CDS), located on the file server, causes computer-based instructional materials to be transferred from the file server through the LAN to selected ones of the student workstations, in which case such student MCU's route computer-based video and audio to their associated video displays and audio transducers. Additionally, under the control of the CDS through student computers and student MCU's, video instructional materials from the LVN may be displayed on video displays and audio transducers of selected ones of the student workstations. As a result of this system, student learning is interactive, individualized, and personalized in a multi-media environment.
