The Impact

Technology plays an important role in everyday life and can be used in education. Video is a source of material that can play an important role in the teaching and learning field. Using videos engages students, aids student retention of knowledge, motivates interest in the subject matter, and illustrates the relevance of many concepts. In this chapter, the authors describe two teaching experiences involving videos, where the students made a video about solving a concrete mathematical problem. In this video, the students should explain the problem resolution to their colleagues (playing the role of teacher). The results of the impact of this kind of project in the students' motivation are also presented.

The Impact

Background: The article underscores the process of knowledge retention for academics in select academic departments in the College of Human Sciences (CHS) at the University of South Africa (UNISA). The knowledge economy is ubiquitous and necessitates that organisations foster innovation and improve efficiency, effectiveness, competitiveness and productivity through knowledge retention. In an academic setting, which is the focus of this article, the situation is no different because there seems to be an accord worldwide that the quality of higher education largely depends on the qualifications of staff and professorial capability in quality research, instruction and doctoral level certification. By implication, it is critical that the retention of knowledge should be prioritised to ensure the curtailment of the impact of knowledge attrition.Objective: The study intends to profile knowledge assets in CHS, determine retention strategies and offer suggestions about regenerating knowledge retention initiatives.Research methodology: A quantitative approach, more specifically the informetrics technique of data mining, was adopted to profile academics in CHS at UNISA.Results: The results confirm the assertion that there is a discrepancy between senior academics who are probably due to leave the university in the next few years, and entrants who will replace them. The issue is worsened by the lack of an institutional framework to guide, standardise, strengthen or prioritise the process of knowledge retention.Conclusion: The study recommends the prioritisation, formalisation and institutionalisation of knowledge retention through the implementation of a broad range of knowledge retention strategies.

The Impact

Time has contributed to most of our daily activities. In the field of understanding how the human brain reacted to specific learning processes, the neuroscientist supports the impact of having multiple learning sessions with the retention of knowledge. Spaced Learning is a product makes out of human's lack of capacity in retaining information and attempts to reduce the forgetting rate. In exploring the condition of how the human mind works and the chances of forgetting, the demonstration of spaced and massed learning in retaining information is recognized in this paper. This paper is aimed to synthesize information on the foundation of Spaced Learning with a focus on language learning, especially to students in academic institutions in Malaysia. This paper used a qualitative design in analyzing documents from articles whereby these articles are synthesized and analyzed using Microsoft excel and the conclusion later on drawn from the analyses. Based on the reviews highlighted in this paper, the practicality of spaced learning is proven in enhancing memory retention in which can contribute to positive performance and can help maximize students' language performance particularly to those who engaged in specific fields of knowledge.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.
