It is possible for a measure to have one and not all of the above criteria’s. If it lacks one of the measurements the chances of the study/research lacking credibility are higher.

________ implies that a performance appraisal system is capable of distinguishing effective from ineffective performers. A. Relevance B. Sensitivity C. Reliability D. Acceptability Correct:

Bang! Bang! “At that instant several gunshots, which sounded like thunder striking the tin-roofed houses, took over town. The sound of guns was so terrifying it confused everyone” (Beah 23). In A Long Way Gone, Ishmael Beah conveys his amazing journey through war and hardship as a child soldier. Sierra Leone--a country on the western coast of Africa--was embroiled in a bloody civil war in the 1990’s. Battles multiplied as bloodshed abounded and as a child in Sierra Leone Ishmael Beah was forced to survive, find food, and face unimaginable dangers. Running from the battle front was also a routine ordeal. At age 13 Beah was captured by the military and brainwashed into using guns and drugs. As a child soldier he perpetrated and witnessed a great deal of violence. At 15 he was rescued and taken to a rehabilitation center. With time and continual treatment, Beah was able to recover, to some extent, and reconnect with his Uncle Tommy who adopted him. He was later chosen to speak to the United Nations in New York City about his experiences as a child soldier. When he returned to Sierra Leone, war broke out throughout in the city where he lived, causing many deaths including his Uncle Tommy. Eventually Beah escaped Sierra Leone and he managed to reach New York City, where he began a new life. Through Ishmael Beah’s book A Long Way Gone, he conveys a central theme of having to survive, at a young age, through the hardships of war with the use of imagery.

| (TCO A,B,C) The measure of how well a property is designed to do the job it is intended to perform is called _________________ .

i) a ‘Performance Assessment’ ii) an ‘Other Evidence Assessment’ (evidence identified from the list below – outputs of work performance)

The Performance Measurement is a way to either measure or give a understandable value to what has been done compared to what was supposed to be done. It applies to all aspects in the working environment, such as procedures, critical activities and processes. In other words, first you set pre-defined goals and give away tasks and responsibilities to other workers, then at the deadline you can compare the achieved results to what the original goal was at the beginning. It is also useful to evaluate not only the final result, but even all the actions taken to get that particular results and the way the actions have been taken as well.

Measuring performance means when a business will measure the quality of the activities that are passing and the quality of the services provided to the customers by employees. It involves creating a simple, but effective, system for determining whether organizations meet objectives. It’s also a process of collecting and reporting information regarding the performance of an individual, group or organizations. It can

The questions in this instrument are weighted a numerical value of zero to three, with three being the highest score on each question.

(Measureable) quality is being measured by scores (areas are being identified by scores of either higher or lower)

Effectiveness: the degree to which something is successful in producing a desired result; success. adequate to accomplish a purpose; producing the intended or expected result: (“Miriam-Webster,” 2017).

Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process

I want to attend the Academy because I love science, mathematics, engineering, and technology. Additionally, I want to pursue a career in STEM and enhance my knowledge in the subject. I’ve loved being involved in STEM projects since third grade when I joined the Gifted and Talented program. I’m extremely interested in STEM which led me to choose the technology elective in eighth grade. People who learn STEM have the ability to change the world which is what I want to do. STEM is everywhere in our daily lives and by learning about it, I could end environmental problems, world hunger, and even find a cure to cancer. STEM involves several real-life situations which leads to numerous enjoyable, challenging, creative, innovative, and fascinating

Validity refers to that measuring tool or approaches can accurately measure things needed to be measured. It can be considered as an extent that measured results reflect investigative contents. Measured results more tend to be identical, validity will be higher, vice versa. Guba and Lincoln (1981) argued that whole social research must include invalidity in order to acquire worthwhile data within both the rationalistic paradigm (quantitative research) and naturalistic paradigm (qualitative research). Some factors can determine the level of validity, which include bias, construct

| might affect how a learner can interact with others or how they view learning especially if they have had previously bad experiences of education.

Polit & Beck (2014) state “reliability is the consistency with which an instrument measures the attribute” (p.202). The less variation in repeated measurements, the more reliable the tool is (Polit & Beck, 2014, p.202). A reliable tool also measures accuracy in that it needs to capture true scores; an accurate tool maximizes the true score component and minimizes the error component (Polit & Beck, 2014). Reliable measures need to be stable, consistent, and equal. Stability refers “to the degree to which similar results are obtained on separate occasions (Polit & Beck, 2014, p.202). Internal consistency refers “to the extent that its items measure the same trait (Polit & Beck, 2014, p. 203). Equivalence refers “to the extent to which two or more independent observers or coders agree about scoring an instrument” (Polit & Beck, 2014, p.204).
