Compiled by Measurement, Assessment, and Evaluation in Education
Ed 1st Year B. Assessment, measurement, evaluation and research are part of the processes of science and issues related to each topic often overlap. Assessment refers to the collection of data to better understand an issue, measurement is the process of quantifying assessment data, evaluation refers to the comparison of that data to a standard for the purpose of judging worth or quality, and research refers to the use of that data for the purpose of describing, predicting, and controlling as a means toward better understanding the phenomena under consideration.
Measurement is done with respect to "variables" phenomena that can take on more than one value or level. The collecting of data assessment , quantifying those data measurement and developing understanding about the data research always raise issues of reliability and validity. Reliability attempts to answer concerns about the consistency of the information data collected, while validity focuses on accuracy or truth. The relationship between reliability and validity can be confusing because measurements e.
However, the reverse is not true: measurements cannot be valid without being reliable. The same statement applies to findings from research studies.
Findings may be reliable consistent across studies , but not valid accurate or true statements about relationships among "variables" , but findings may not be valid if they are not reliable. At a miniumum, for a measurement to be reliable a consistent set of data must be produced each time it is used; for a research study to be reliable it should produce consistent results each time it is performed.
For example, the variable "gender" has the values or levels of male and female and data could be collected relative to this variable. The judgment emanating from a test is not necessarily more valid or reliable from the one deriving from qualitative procedures since both should meet reliability or validity criteria to be considered as informed decisions. The area circumscribed within quantitative decision-making is relatively small and represents a specific choice made by the teacher at a particular time in the course while the vast area outside which covers all non-measurement qualitative assessment procedures represents the wider range of procedures and their general nature.
This in turn can lead to more illuminating insight about future progress and attainment of goals. However, the options discussed above are not a matter of either-or traditional vs. Based on the above discussion, grading grading could be considered a component of assessment, i. Generally, grading also employs a comparative standard of measurement and sets up a competitive relationship between those receiving the grades.
Most proponents of assessment, however, would argue that grading and assessment are two different things, or at least opposite pole on the evaluation spectrum. For them, assessment measures student growth and progress on an individual basis, emphasizing informal, formative, process-oriented reflective feedback and communication between student and teacher. Ultimately, which conception you supports probably depends more on your teaching philosophy than anything else.

Herman, J. A practical guide to alternative assessment. Test validity. Validity is often assessed along with reliability - the extent to which a measurement gives consistent results. An early definition of test validity identified it with the degree of correlation between the test and a criterion.
Construct validity refers to the extent to which operationalizations of a construct e. For example, to what extent is an IQ questionnaire actually measuring "intelligence"? Content validity evidence involves the degree to which the content of the test matches a content domain associated with the construct.
For example, a test of the ability to add two numbers should include a range of combinations of digits. A test with only one-digit numbers, or only even numbers, would not have good coverage of the content domain. Content related evidence typically involves subject matter experts SME's evaluating test items against the test specifications.
Indeed, when a test is subject to faking malingering , low face validity might make the test more valid. Criterion validity evidence involves the correlation between the test and a criterion variable or variables taken as representative of the construct. In other words, it compares the test with other measures or outcomes the criteria already held to be valid. For example, employee selection tests are often validated against measures of job performance the criterion , and IQ tests are often validated against measures of academic performance the criterion.
Again, with the selection test example, this would mean that the tests are administered to applicants, all applicants are hired, their performance is reviewed at a later time, and then their scores on the two measures are correlated.
The validity of the design of experimental research studies is a fundamental part of the scientific method, and a concern of research ethics. Without a valid design, valid scientific conclusions cannot be drawn. One aspect of the validity of a study is statistical conclusion validity - the degree to which conclusions reached about relationships between variables are justified. This involves ensuring adequate sampling procedures, appropriate statistical tests, and reliable measurement procedures.
Eight kinds of confounding variable can interfere with internal validity i. To what extent did the chosen constructs and measures adequately assess what the study intended to study? A major factor in this is whether the study sample e.
Other factors jeopardizing external validity are:. Because each judge is basing their rating on opinion, two independent judges rate the test separately. Items that are rated as strongly relevant by both judges will be included in the final test. Email This BlogThis! Subscribe to: Posts Atom.
Assessment, measurement and evaluation
The Methodology of the development procedure has been also classified into two main types, based on their execution duration. The method is based on a five-dimensional model that includes a participative, an interactive, a social, a cognitive and a teaching dimension. Measurement vs Evaluation. A teacher measures Mr. This, integration ensures that the final evaluation is not based merely on facts and notions but rather on, more complex skills, such as solving complex multidisciplinary problems, creatively transferring, solution strategies to new contexts, formulating and verifying hypothesis, choosing and discussing, appropriate inquiry methods, sharing and negotiating knowledge through participation in a virtual, Another important change is that summative and formative evaluation are partly based on the same, methods. Furthermore, to demonstrate the applicability of our approach, we present a case study, where we built and apply a personalized gamification model based on the ontological structures defined here. Access scientific knowledge from anywhere.

Having a true or correct view of the universe, how it works, and how we as human beings are influenced by our nature and our surroundings are important goals for educators. In general, there are four ways or methods by which truth about phenomena can be ascertained. First, we can know something is true because we trust the source of the information.
When defined within an educational setting, assessment, evaluation, and testing are all used to measure how much of the assigned materials students are mastering, how well student are learning the materials, and how well student are meeting the stated goals and objectives. Although you may believe that assessments only provide instructors with information on which to base a score or grade, assessments also help you to assess your own learning. Education professionals make distinctions between assessment, evaluation, and testing. However, for the purposes of this tutorial, all you really need to understand is that these are three different terms for referring to the process of figuring out how much you know about a given topic and that each term has a different meaning. To simplify things, we will use the term "assessment" throughout this tutorial to refer to this process of measuring what you know and have learned. Hopefully by this point in your life you have discovered that learning can be fun!
Measurement is a systematic process of determining the attributes of an object. It ascertains how fast, tall, dense, heavy, broad, something is. However, one can make measurements of physical attributes only and if one has to measure those attributes which cannot be measured with the help of tools. That is where the need for evaluation arises.

К счастью, Дэвид это обнаружил. Он проявил редкую наблюдательность. - Но ведь вы ищете ключ к шифру, а не ювелирное изделие. - Конечно. Но я думаю, что одно с другим может быть связано самым непосредственным образом.
Внимательный и заботливый, умный, с прекрасным чувством юмора и, самое главное, искренне интересующийся тем, что она делает. Чем бы они ни занимались - посещали Смитсоновский институт, совершали велосипедную прогулку или готовили спагетти у нее на кухне, - Дэвид всегда вникал во все детали. Сьюзан отвечала на те вопросы, на которые могла ответить, и постепенно у Дэвида сложилось общее представление об Агентстве национальной безопасности - за исключением, разумеется, секретных сторон деятельности этого учреждения. Основанное президентом Трумэном в 12 часов 01 минуту 4 ноября 1952 года, АНБ на протяжении почти пятидесяти лет оставалось самым засекреченным разведывательным ведомством во всем мире. Семистраничная доктрина сжато излагала программу его работы: защищать системы связи американского правительства и перехватывать сообщения зарубежных государств. На крыше главного служебного здания АНБ вырос лес из более чем пятисот антенн, среди которых были две большие антенны, закрытые обтекателями, похожими на громадные мячи для гольфа.
Мне нужен только ключ. - Какой ключ. Стратмор снова вздохнул. - Тот, который тебе передал Танкадо. - Понятия не имею, о чем. - Лжец! - выкрикнула Сьюзан. - Я видела твою электронную почту.
Когда-нибудь он станет мировым стандартом.
Но общественные организации типа Фонда электронных границ считали. И развязали против Стратмора непримиримую войну. ГЛАВА 24 Дэвид Беккер стоял в телефонной будке на противоположной стороне улицы, прямо напротив городской больницы, откуда его только что выставили за причинение беспокойства пациенту под номером 104, месье Клушару.
Он просиял. - Второй раз за один вечер. Что подумают люди. - В шифровалке проблемы.
Боюсь, что в ТРАНСТЕКСТЕ завелся какой-то неизвестный вирус. - Вирус? - снисходительно хмыкнул Стратмор, - Фил, я высоко ценю твою бдительность, очень высоко. Но мы с мисс Флетчер проводим диагностику особого рода. Это файл высочайшей сложности.
