Explicit learning

In the third study (Van Vorst, 2013), factor analysis extracted emotion- and value-related scales (see Table 2). Students had to rate their interest in learning chemistry knowledge starting from a presented context. As this situation was rated without an explicit reference to content knowledge, items asked for interest in the introductory context as well as if it was used in the chemistry classroom. Because situations did not include an explicit learning activity, activity-related interest scales could be excluded. A reason for the extraction of both valences can be seen in the procedure which combined a large sample with a variety of situations to be rated with regard to different characteristics. 

Estes et al., 2010). This involves explicit learning objectives for each lesson, a clear and engaging presentation of materials, and multiple opportunities for students to participate in class through examples, in class activities, and models. 

The two ways of learning - deductive and inductive - have already been mentioned. Quite a few properties of chemical compounds can be calculated explicitly. Foremost of these are quantum mechanical methods. However, molecular mechanics methods and even simple empirical methods can often achieve quite high accuracy in the calculation of properties. These deductive methods are discussed in Chapter 7. 

Molecular models such as the one shown often do not explicitly show double and triple bonds Write a Lewis structure for this hydrocarbon showing the location of any multiple bonds Specify the hybndization state of each carbon (You can view this model in more detail on Learn mg By Modeling)... 

This level of simplicity is not the usual case in the systems that are of interest to chemical engineers. The complexity we will encounter will be much higher and will involve more detailed issues on the right-hand side of the equations we work with. Instead of a constant or some explicit function of time, the function will be an explicit function of one or more key characterizing variables of the system and implicit in time. The reason for this is that of cause. Time in and of itself is never a physical or chemical cause—it is simply the independent variable. When we need to deal with the analysis of more complex systems the mechanism that causes the change we are modeling becomes all important. Therefore we look for descriptions that will be dependent on the mechanism of change. In fact, we can learn about the mechanism of... 

The Field of Numerical Analysis.—As used here, numerical analysis will be taken to represent the art and science of digital computation. The art is learned mainly by experience hence, this chapter will be concerned with explicit techniques and the mathematical principles that justify them. Digital computation is to be contrasted with analog computation, which is the use of slide rules, differential analyzers, model basins, and other devices in which such physical magnitudes as lengths, voltages, etc., represent the quantities under consideration. 

The following sections therefore review both pictures and numerical approaches that can help to communicate how value can best be created by R D, despite uncertainty. Because of all the uncertainties involved in predicting the future, and predicting what might be learned from different kinds of research, all effective research performance models must explicitly incorporate assumptions about sources and levels of uncertainty. We believe that this is the single most important area for improvement in research simulations. 

The notation introduced above allows us to make now a more explicit and condensed enumeration of the major characteristics and differences, with respect to the Q, ij/,f,S) key components, that separate our learning methodologies from other approaches. 

These disadvantages are overcome by the methodology we will describe in the subsequent paragraph developed by Bakshi and Stephanopoulos. Effects of the curse of dimensionality may be decreased by using the hierarchical representation of process data, described in Section III. Such a multiscale representation of process data permits hierarchical development of the empirical model, by increasing the amount of input information in a stepwise and controlled manner. An explicit model between the features in the process trends, and the process conditions may be learned... 

Complex information needs may be difficult to narrow in scope. Sometimes learning a bit more about the subject before searching is helpful and time efficient in the end. Textbooks are helpful to provide a background prior to searching. Searching is most efficient when the search question is explicitly stated.
