The purpose of this study was to find out teachers' preferred teaching sequence for basic chemistry topics in Physical Science in South Africa, to obtain their reasons underpinning their preferred sequence, and to compare these sequences with the prescribed sequences in the current curriculum. The ...

For example, in their answers to questions such as the one included in Figure 3, many students used the terms atom, proton, and electrons without understanding their meaning. These types of answers could have simply been scored as wrong or not successful, but that would have ignored ...
It has no scaffolding linking it to the vibrant sentience of life. Regardless of its level of sophistication and power, it is nothing other than a pattern recognition device. AI theoreticians tend to think of intelligence as substrate independent—meaning that the set of patterns and linkages ...
Toxicity data exist for all of the examples presented, meaning that a TTC would not be used for these chemicals in practice; however, they serve as useful cases for checking the validity of the approach. Table 2. Example of application of the tiered decision tree to assessing exposure to ...
The chemical regeneration process has been extensively applied to reactivate biochar, supporting its reusability and leading to significant operating cost reduction. However, no recent review discusses the effectiveness of biochar chemical regeneration.

you will find that the author has chosen to round out his work with a summation of what the book is all about. That is, having written a whole book on a specialized subject in which he is probably an authority, he finds that he also has ideas about the larger meaning of, or larger...
the axes of the semantic space that capture each of the topics are not necessarily orthogonal. The orthogonal features produced by SVD, whose linear combination can reproduce the documents, thus lose the intuitive meaning of sets of terms (see the point about interpretability below). In this sens...
