Ideal VLEs in Higher Education - Assignment Example Another region-wide problem is the support of most excellent tradition in â€Å"instructional design† (Weller, p. 33, 2007). In particular, it involves the organized growth of knowledge-giving systems, and it includes the complete expansion procedure from scrutiny of learning requirements, as well as objectives by the expansion of a delivery scheme to attain identified objectives. In addition, analysis has indicated that its basis is on an awareness of educational as well as instructional theory (Weller, p. 33, 2007). Moreover, it is an observation that educational design has been ignored due to lack of supplies and due to its anonymity. There is a common inclination in teaching to call attention to the technology-centric features with no regard for the education design development, and educational instructors do not put efforts in this respect, as they are likely to concentrate on common explanatory hypothetical forms, instead of goal-focussed forms of instant use to experts. At this point, a simple language designer’s practicum applying a state-of-the-art form of educational design is required. Teaching faculty complains about deficiency of knowledge of educational standards on the part of â€Å"educational designers, who pays attention on transmission instead of a ‘constructivist approach† (Gillespie et al, p. 78, 2007). At foundational stage the issues with e-learning are systemic instead of technical. What needed is grouping among the identified groups of interests, which are students, teachers and administrators. In addition, researchers (Gillespie et al, p. 78, 2007) have indicated that the internet has turned out to be three times less-useful for individuals with optical impairments than those without them.

From this discussion it is clear that teaching faculty complains about deficiency of knowledge of educational standards on the part of â€Å"educational designers, who pays attention on transmission instead of a ‘constructivist approach†. At foundational stage the issues with e-learning are systemic instead of technical. What needed is grouping among the identified groups of interests, which are students, teachers and administrators. In addition, researchers (Gillespie et al, p. 78, 2007) have indicated that the internet has turned out to be three times less-useful for individuals with optical impairments than those without them. In the result, Virtual Learning Environments have been proven to be six times as hard to use as a result of their intricacy, as well as the belief that learning will take place in use.As the report discusses  supporters of user-focused design call attention to the need to support fine usability - at times termed universal design or design for everyone - contrasting to ease of access in remoteness. As a Virtual Learning Environment resource may be technically available, that does not indicate it will be functional. It has to be taken into consideration that Virtual Learning Environments are planned to facilitate people in learning. Usability issues in VLEs may only be temporary disturbance or irritation, although they may as well be the basis of cognitive burden, interruption on entire procedure, resulting in at least low standard of education and awfully, total dejection.

How do dinosaurs become extinct Research Paper Example | Topics and Well Written Essays - 2250 words

How do dinosaurs become extinct - Research Paper Example Extinction gets certified when there is no surviving individual that is able to create a new generation through reproduction. Functional extinction describes this state where only a countable few specie members survive, and can neither thrive nor reproduce. This could be as a result of age, lack of representation of both sexes and poor health and distribution. The actual point of extinction is difficult to identify due to the larger potential range that a species has, and the determination of extinction is usually done retrospectively. Dinosaur is a term that gets used to refer to a wide variety of chiefly terrestrial, carnivorous and herbivorous reptiles of the now extinct Ornithischia and Saurischia orders that thrived during the Mesozoic Era. They are thought to have been the biggest known land animals that shared a specific common anatomy. True dinosaurs had legs ankles and hips somewhat structured like a bird’s, such that the legs were mobile under the body and not outside like present lizard species. Sir Owen Richard formed the name dinosaur in 1841 to identify the remains of extinct reptiles. The name dinosaur originated from the Greek word deinos which means fearfully terrible, and sauros, which means lizard. Many explanations have been given, some of which have been convincing, about the extinction of dinosaurs. These explanations range from disease, volcanic eruption, asteroid impact, and climate change, which is the most supported of all theories (Page 56). II CASE PRESENTATION A. ASTEROID IMPACT THEORY The Asteroid Impact theory gets used by many scientists to explain the disappearance of dinosaurs from the face of the earth. As such, several variations of this theory exist, some of which are largely similar with minor differences setting them apart. The asteroid extinction theory gets sometimes referred to as the K-T Asteroid Theory, and the Alvarez Asteroid Impact. All these theories vary marginally, but are all centered on a single event though to have prematurely destroyed most of the life forms on earth dating back 65 million years ago (Norman 77). The asteroid theory got first fronted by the father son team of Walter and Luis Alvarez in1978. Walter and Luis analyzed sediment sam ples collected in the 1970s at the K-T layer close to the town of Gubbio in Italy. The tests revealed high concentrations of the element Iridium, rarely found on earth, but found in abundance in meteorites. Upon analysis of more sediment of K-T boundary strata from other regions of the globe, high concentrations of Iridium got recorded, as well. Guided on the basis of the average sediment thickness, team Alvarez suggested that a large comet or asteroid, perhaps several miles in diameter would be needed to spread as much Iridium as was recorded all over the earth. The impact of such an asteroid hitting the earth would be a massive explosion, massive fires and total annihilation of whatever life existed then, dinosaur inclusive (Parsons 95). A crater, partly submerged in water and worn down, got found along the Mexican Yucatan Peninsula whose creation largely coincides with the K-T boundary. Scientist from the world renowned National Aeronautics and Space Administration estimate that the Chicxulub Crater as it is currently known would have gotten formed as a result of the action of a 6 to 12 mile diameter asteroid. The crater is currently about 130 miles wide (Debus 66). Scientists from the Southwest Research Institute in Colorado have traced the asteroid path back into space. Their calculations revealed that a collision between an asteroid that was 100 miles wide called Baptistina, and another asteroid of relatively small size out beyond Mars’
