When measure a complex concept such as love, intelligence, motivation, there is no direct measure as when we measure height, weight. Those complex concepts are also linked to behavior. The construct can be referred as hypothetical constructs. “Hypothetical” because they are inferred from theories and other behavior, and “constructs” because they must be constructed by using a database of observations that can be measured. (clayton)
Practically the construct is defined by how it is measured. This is called an operational definition.
The meaning of our study rests on how we objectively observe the construct or behavior of interest. Thus, developing a reliable and valid set of procedures for measuring our variables is crucial for the

In science (e.g. social sciences and psychometrics), construct validity refers to whether a scale measures or correlates with the theorized psychological scientific construct (e.g., "fluid intelligence") that it purports to measure. In other words, it is the extent to which what was to be measured was actually measured. It is related to the theoretical ideas behind the trait under consideration, i.e. the concepts that organize how aspects of personality, intelligence, etc. are viewed.[1] The scale seeks to operationalize the concept, typically measuring several observable phenomena that supposedly reflect the underlying psychological concept. Construct validity is a means of assessing how well this has been accomplished. In lay terms, construct validity answers the question: "Are we actually measuring (are these means a valid form for measuring) what (the construct) we think we are measuring?"
A construct is not restricted to one set of observable indicators or attributes. It is common to a number of sets of indicators. Thus, "construct validity" can be evaluated by statistical methods that show whether a common factor can be shown to exist underlying several measurements using different observable indicators. This view of a construct rejects the operationist past that a construct is neither more nor less than the operations used to
Understanding the term construct, is important as an writer. Construct, which are “...unquestioned claims that can be questioned, contested, redefined, or reinvented,” (Wardle, Downs 2011, 888) , a definition
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.

Constructivism is reflecting on the experiences we have had in order to create our own understanding of the environment me live in. For instance, lets say I had and old sewing machine that I used all the time but now broke. I visit a sewing machine shop in order to buy a new one. The only machines available are newer models of the machine I owned, with different buttons and features. My previous experience with my machine will guide me into using the new machine. By simply learning a few extra steps, I would now be able to use the new model thanks to by previous experience, this is considered constructivism.
Now, it is time to give an overview of some of the design threats to construct validity. If the researcher did not define the construct efficiently than it can lead to the inadequate preoperational explication of constructs threat (Trochim & Donnelly, 2008). Next, is the mono-operation bias, which is the use of the study program only one time and one place (Trochim & Donnelly, 2008). Third, the mono-method bias is the use of any one measure or observation (Trochim & Donnelly, 2008). Finally, the confounding constructs and the levels of constructs threat (Trochim & Donnelly, 2008). Overall, this threat to construct validity is a labeling issue like some of the other threats to construct validity (Trochim & Donnelly, 2008). However, there are more design threats than listed in this paper to construct
Construct refers to any complex psychological concept. Examples would be a person’s motivation, anger, personality, intelligence, love, attachment, or fear. A Construct’s height, weight or depth cannot be
In psychological assessment of any kind, validity is defined as “the degree to which all the accumulated evidence supports the intended
Choosing an instrument to measure study variables is a very crucial in research. If a researcher chose to use an existing
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
In the article, Measurement Matters: Assessing Personal Qualities Other Than Cognitive Ability for Educational Purposes, by Angela L. Duckworth and David Scott Yeager, address confusion over terminology, debate over the optimal name for this broad category of personal qualities obscures substantial agreement about the specific attributes worth measuring, discuss advantages and limitations of different measures, compare self-report questionnaires, teacher-report questionnaires, and performance tasks, discuss how each measure’s imperfections can affect its suitability for program evaluation, accountability, individual diagnosis, and practice improvement. It also states only measurement makes it possible to observe patterns and to
Throughout this course I have learned many things about research at an introductory level. Research is a critical part of all of our lives in many ways. God blesses each of us with a degree of common sense and we all learn from observing others even as babies, we learned behaviors and skills by observing our parents. Walking through experiences throughout life teach us a lot we need to know as well but sometimes we have to take a better approach when we need to learn about certain things. Many of us know that what works in some situations or with certain individuals doesn’t always work or is the safest option for another situation. Controlled and precisely organized study allows scientists to compare and examine contrasting methods and concepts, also helps them to discover various approaches and be able to learn from individual’s behaviors and experiences. I will act as the case study throughout this paper in order to observe what I have learned about.
Construct is defined as "a representation of the universe, a representation erected by a living creature and then tested against the reality of that universe" (Kelly, 1955, p.12). According to Kelly, people make sense of the world by formulating their own models. They interpret things happened around them and organize those interpretations to construe their own models of reality. These models are called "constructs" by Kelly.
Constructivism is a coherent theory of learning that emerged as a prevailing paradigm in the last part of the twentieth century. Constructivism is a theory which brings cogitation to pedagogy (Bruner, 1966). Constructivism capitalizes on the ways in which human beings create their own personal construct of reality by understanding and experiencing the world. The main underlying assumption of constructivism is that individuals are actively involved right from the birth in constructing personal meaning.
In studies testing the model, Fiedler and his colleagues developed instru-ments to measure each of these three situational variables." Of the three situa-tional
Constructivism is the theory that humans construct knowledge and meaning from their experiences. This idea that people learn from experience and not just from hearing lectures was revolutionary and gave birth to the experimental learning approach that is more powerful than lectures and worksheets. By directing their own learning processes, students understand concepts better. In essence constructivism is the theory of how we learn.
