In this proposed study, the tools will use to gather data are include an achievement test, a attitude Through TIMESS survey .
According to Creswell (2015), the survey instrument is defined as a tool in quantitative research in which investigators administer to group of people to articulate their perception, feeling about the research problem. The researcher will adopt an existing survey instrument developed by Davis (1989). The survey items for this proposed study will be based on Davis’s original work with slight modifications of items to fit the proposed study. The researcher received Davis’s permission to use the survey instrument to conduct the study (see Appendix A). Davis (1989) developed an instrument using five-point Likert items (Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree), where each item is an indicator of an individual’s behavioral intention regarding perceived usefulness and perceived ease of use. The adopted survey will consist of a 24-item tool. The TAM survey instrument measures the users’ behavioral intention to use webinars. In this study, the perceived usefulness construct has 7 items, ease of use construct has 5 items, and the behavioral intention construct has 4 items. This survey will be administered via the web to the faculty members at the IPA (See Appendix C). In addition, the survey will include a section to collect participants’ demographic information such as gender, age, educational level, and years of experience.
Validity evidence of the TAM instrument is essential to make sure the items in each construct will measure what it is intended to measure. The TAM survey instrument intended to study the acceptance of new technology. One way to examine validity evidence about an instrument is to explore previous studies that have used the TAM survey instrument in their studies. The TAM instrument was applied in many studies and has been shown to have good scored validity in measuring users’ behavioral intention to determine actual systems use (Abu-Dalbouh, 2013; Ahmed & Ahlan, 2015; Malik et al., 2015; Park, 2009).
The TAM survey instrument has demonstrated evidence of high reliability and validity, not only in the original work but also in other studies utilizing it (see Abu-Dalbouh, 2013). For instance, Park in an investigation on e-learning usage successfully utilized the model (2009). The study attained Cronbach alpha values that ranged from 0.86 to 0.97 in various categories. The reliability of ease of use was 0.92 and the reliability was 0.97 for perceived usefulness. As a result, validity range for convergent and discriminant were acceptable (Davis, 1989).
Research that analyzed the e-learning behavior among the learners utilizing the TAM model yielded equivalently good reliability and validity evidence. Perceived ease of use and usefulness attained a Cronbach alpha of 0.93 and 0.88, respectively (Park, 2009). Correlation values for the study were an average of r = 0.644 when correlated to the constructs, which according to Park (2009) were within the acceptable range. Besides, additional research conducted by Ahmed and Ahlan (2015), utilized the TAM model to investigate perception of using online services. The study attained a high reliability with a Cronbach alpha value of 0.947. The study had a Cronbach alpha of 0.842 for Perceived usefulness and a Cronbach alpha of 0.929 for perceived ease of use (Ahmed and Ahlan, 2015). Validity evidence also has been established by different researchers who have used it with different samples and in different cultures. According to Park (2009), high reliability and validity evidence for the original tool as well as secondary tools enhance its applicability among other researchers. However, reliability and validity exist as properties of data within a particular context, thus a pilot study will be conducted with (N = 20) participants. There will be some necessary changes to the instrument after the pilot study, and any applicable required changes will be made depending on the findings of the pilot study.

Note:

Engagement survey:

Also, I attached a study that use this survey.

Three things I need to cover in this paper:

– Define the TIMESS Instrument.
– Write about the studies that use this survey.
– Write about the reliability for the Instruments
– Write about the validity for the Instruments
