Concept introduction Reliability and validity are important concepts in scientific research. “Reliability” refers to how consistent a test's result is, while “validity” refers to the extent to which the test measures what it is supposed to. These concepts determine the usefulness of a test and allow us to infer whether it is a good tool to assess the given construct.

Expert Solution & Answer

Explanation of Solution

Answer and explanation

Recently, there has been an increase in the use of standardized tests in schools. While they do usually happen to be valid and reliable, most of the tests that a student takes in school are not tested for these properties. Class tests have face validity, implying that it looks from the question that the test is measuring what it is supposed to, but that does not correspond to content or construct validity. Since most of the tests are based on the information given in textbooks, they have some content validity.

When it comes to reliability, class tests that are objective or are based on facts tend to have high inter-rater reliability, while those that measure a subjective quality, such as creative writing and art, tend to have low inter-rater reliability. In general, the reliability and validity of these tests depends on the test maker. Without any formal analysis, one cannot ascertain how useful a test it is.

Tests that are published in magazines and are available online rarely have any validity or reliability. Since they often do not operationalize the variable that they claim to measure, these tests do not have high validity or reliability. The aim of these tests is to have high face validity, to make the test taker feel that the test is useful. Hence, they lack any real validity. Also, since many of these tests measure variables that are influenced by extraneous factors, such as mood, they tend to have low test-retest reliability.

As we embark on this 10-week course on the psychology of creativity, I encourage each of you to evaluatethe various theories and ideas presented in the course from multiple perspectives. Specifically, reflect onhow the given theory/concept does or doesn’t capture your own experience, when engaged in creativeendeavours. Then, because no one theory is likely to have universal applicability, consider whether itseems to capture aspects of the creative process you’ve observed in others. Also think about whether itcaptures elements of your own evaluation of creative work (including the work of those around you aswell as the work of well-known artists).Although no one theory is likely to explain or describe everything about creativity, the so-called “Four Cs”discussed in this week’s readings give us one starting point, to classify subtypes of creativity. Kaufmanand Beghetto (2013) describe the following types of creativity:• Big-C: Genius-level works, generally regarded as masterpieces. Their…

This unit introduces students to identity formation theories and how our identities create roles that interact in society. This activity aims to use these concepts to connect students' understandings of how they curate their own personal and social identities to fit in with social roles and expectations. Instructions Reflect on the article by Ravishankar (2020). What’s wrong with asking, ‘Where are you from?’ Have students reflect on their identity and whether they’ve been asked this question before. How did it feel? What can it make someone feel about their identity? Drawing on the discussion from this unit, analyze how social and individual identity can help us better understand who we are in relation to the world/culture/society around us.
