Identifying learning behaviors, which can indicate the contribution of the proposed learning method and research instruments to be used for measuring the outcomes.2. Determining the concepts and subjects, in which the proposed approach can lead to Page 11.779.3 efficient learning. This can possibly affect developing new frameworks that match the approach.3.

If the student response is correct the engine moves to the nextquestion. If the response is incorrect, the student can be asked a new question or series ofquestions that are designed to discover where the student made an error. Alternatively, theauthor might elect to ask the same question for some maximum number of iterations, providingadditional diagnostic information after each iteration. If

/.BackgroundEngineering in Kindergarten and First GradeThe Technology/Engineering standards set by the state of Massachusetts for kindergartenand first grade students focus on two areas: “Materials and Tools” and “EngineeringDesign”.1 Since these topics are absolutely fundamental to higher-level engineering, theMassachusetts Department of Education requires that basic concepts behind materials,tools, and engineering design be taught at an early age. These concepts include:characteristics/uses of natural and manmade materials; uses of simple tools such as rulersand scissors; uses of simple machines, such as levers and pulleys; and the ways in whichanimals use body parts as tools, as in the case of tails and beaks.

The new professor will eventually burn out, and may have significant personal issuesthat they need to deal with. Taking some time off to relax and be renewed is important.Recommendations for implementing an effective mentoring programWe have the following recommendations.1. An effective new faculty orientation program is very important. However, orientation alone is not mentoring. If a university wishes to mentor its new faculty much more will be required.2.

Arisholmet al.1 point out that static analysis of codes coupling cannot be directly applied to object-oriented software due to polymorphism and run-time binding. Thus, they analyze dynamiccoupling of object-oriented software. They discover that dynamic export coupling can be aneffective indicator of change proneness.

Q3 requires reading a verbal statement and carrying out a calculus integration. It does relateto course topics, but that is incidental at this point. #1 is correct. #2 would be the result if thequestion were misinterpreted as dN/dt = - aN0 or if the integration process were misunderstood.Very few students answered this question within the allotted time.

Further,design is: open-ended, iterative, creative, collaborative, goal-driven, process-intensive, product-focused, customer-oriented, value-added, and constrained by society. Learner and solutiondevelopment usually progresses from a state of students’ fragmented understanding and ideas toa more mature state of integrated understanding and design solutions.The proposed conceptual model for engineering design identifies four areas of performance thatdescribe design: (1) personal capacity, (2) team processes, (3

The course relies heavily onMatlab and the students' ability to think through what a given algorithm should do to aid them inbridging the gap between the three areas. To achieve this, formal graded emphasis was placed onteaching students to think and work through the rote operations of numerical techniques beforeattempting to generate programs. The goal was to generate, as Connolloy put it, a "PriorKnowledge Environment"1 wherein students had thorough prior knowledge of a technique beforetrying to translate that knowledge into programming language to solve
