Develop a range of instructional and assessment methods and test preparation methods. Instruction Linda Gojakformer NCTM President, noted that "Over the last three decades a variety of instructional strategies have been introduced with a goal of increasing student achievement in mathematics. Such strategies include individualized instruction, cooperative learning, direct instruction, inquiry, scaffolding, computer-assisted instruction, and problem solving" with the flipped classroom being a recent addition to the list para. Blended learning is also on the rise, which adds online learning to traditional classrooms.
Introduction Today I thought I'd talk about a neat design pattern that doesn't seem to get much love: In its fullest form it's also sometimes called the Prototype Pattern.
People use this pattern all over the place, and I'll give you a nice set of real-life examples in a little bit. It's a design pattern that's useful in every programming language, and as we'll see shortly, it's also pretty darn useful as a general-purpose persistence strategy.
But even though this pattern is near-universal, people don't talk about it very often. I think this is because while it's remarkably flexible and adaptable, the Properties Pattern has a reputation for not being "real" design or "real" modeling.
In fact it's often viewed as a something of a shameful cheat, particularly by overly-zealous proponents of object-oriented design in language domains or relational design in database domains. I hope to offer a different and richer perspective here. With luck, this article might even help begin the process making the Properties Pattern somewhat fashionable again.
Three Great Schools of Software Modeling Before I tell you anything else about the Properties Pattern, let's review some of the most popular techniques we programmers have for modeling problems.
I should point out that none of these techniques is tied to "static typing" or "dynamic typing" per se. Each of these modeling techniques can be used with or without static checking.
The modeling problem is orthogonal to static typing, so regardless of your feelings about static checking, you should recognize the intrinsic value in each of these techniques. Class Modeling You know all about this one.
Class-based OO design is the pound gorilla of domain modeling these days. Its appeal is that it's a natural match for the way we already model things in everyday life.
It can take a little practice at first, but for most people class modeling quickly becomes second nature. Although the industry loves OO design, it's not especially well liked as an academic topic.
This is because OO design has no real mathematical foundation to support it — at least, not until someone comes along and creates a formal model for side effects.
The concepts of OOP stem not from mathematics but from fuzzy intuition. This in some sense explains its popularity, and it also explains why OOP has so many subtly different flavors in practice: Industry folks can never quite agree on what OOP is, but we love it all the same.
Relational Modeling Relational database modeling is a bit harder and takes more practice, because its strength stems from its mathematical foundation. Relational modeling can be intuitive, depending on the problem domain, but most people would agree that it is not necessarily so: Object modeling and relational modeling produce very different designs, each with its strengths and weaknesses, and one of the trickiest problems we face in our industry has always been the object-relational mapping ORM problem.
It's a big deal. Some people may have let you to believe that it's simple, or that it's automatically handled by frameworks such as Rails or Hibernate. Those who know better know just how hard ORM is in real-world production schemas and systems. Usually XML is used to model data, but it can also be used to model code.
In many domains, programmers will decide on an XML representation before they've thought much about the class model, because for those domains XML actually offers the most convenient way of thinking about the problem.
I mention this not to start a fight, but only to illustrate that XML is a third modeling technique in its own right. It has both natural resonances and surfaces of friction with both relational design and OO design, as one might expect.Prevent Plagiarism.
Identify unoriginal content with the world’s most effective plagiarism detection solution. Manage potential academic misconduct by highlighting similarities to the world’s largest collection of internet, academic, and student paper content. Inventory systems provide companies with the ability to track the supplies and raw materials needed to build product to meet customer demand.
The accuracy of the inventory system affects purchasing, planning and production departments in the organization. Nike's inventory management solution was to change the software, remove the bugs, and extremely perfect how the software in future demands for inventory.
It was that simple. Figure issues in Nike is how crucial it is to manage inventory and your inventory management system completely.

Abstract. The advent of agriculture has ushered in an unprecedented increase in the human population and their domesticated animals. Farming catalyzed our transformation from primitive hunter-gatherers to sophisticated urban dwellers in just 10, years.
