This article is about making correction in Tarray, Singh, and Zaizai model and further improving it when stratified random sampling is necessary. This is done by using optional randomized response technique in stratified sampling using a combination of Mangat and Singh, Mangat, and Greenberg et al. models. The suggested model has been studied…

Despite the strong criticisms, mass student surveys play an important role in the quality assurance process of national higher education systems. While some national higher education systems have a long history of using student surveys to inform teaching and course quality improvement (e.g. the UK, Australia), in Italy, where the quality assurance…

The randomized response technique (RRT) is an effective method designed to obtain the stigmatized information from respondents while assuring the privacy. In this study, we propose a new two-stage RRT model to estimate the prevalence of sensitive attribute ([pi]). A simulation study shows that the empirical mean and variance of proposed estimator…

In common sociological research, income inequality is measured only at the aggregate level. The main purpose of this article is to demonstrate that there is more than meets the eye when inequality is indicated by a single measure. In this article, I introduce an alternative method that evaluates individuals' contributions to inequality as well as…

Background: Engineers operate in an increasingly global environment, making it important that engineering students develop global engineering competency to prepare them for success in the workplace. To understand this learning, we need assessment approaches that go beyond traditional self-report surveys. A previous study (Jesiek et al.,…

Two of the central issues in comparative judgement (CJ), which are perhaps underexplored compared to questions of the method's reliability and technical quality, are "what processes do judges use to make their decisions" and "what features do they focus on when making their decisions?" This article discusses both, in the…

The purpose of this descriptive analysis study was to investigate high school music teachers' levels of satisfaction with the teacher evaluation practices used by administrators and music supervisors in the Commonwealth of Virginia. Virginia high school music teachers (n = 76) were surveyed to collect data used to determine their levels of…

Purpose: Measuring internal response of online learning is seen as fundamental to absorptive capacity which stimulates knowledge assimilation. However, the evaluation of practice and research of validated instruments that could effectively measure online learning response behavior is limited. Thus, in this study, a new instrument was designed…

Pressure on evaluators has been investigated recently by surveys in the USA, the UK, Germany, and Switzerland. This study compares the results of those studies regarding pressure on evaluators in different countries. The findings suggest that independence of evaluations does not exist for many respondents. Moreover, the person who commissioned the…

The demands on schools, teachers, and students continue to increase as greater accountability measures are put into place at all levels. For teachers to meet these increased demands, it is important that they be provided opportunities to improve and enhance their content knowledge and pedagogy. One way to ensure the provision of these…

This study compares cost, completion times, and percent completion of electronic tablet (n = 244) to paper-based (n = 398) questionnaires administered to participants of scenic raft trips on the Snake River, Grand Teton National Park. We hypothesized e-tablet questionnaires would (1) cost less (2) be completed faster and (3) be completely filled…

Evaluators can work with brief units of text-based data, such as open-ended survey responses, text messages, and social media postings. Online crowdsourcing is a promising method for quantifying large amounts of text-based data by engaging hundreds of people to categorize the data. To further develop and test this method, individuals were…

The laboratory is an integral component of engineering education, resulting in a multitude of studies. Generally, the research focus is on the laboratory innovation, rather than learning itself. It is observed that empirical evidence is strongly built around student perceptions of their learning or experience via survey instruments; and in some…

Existing research on "school effectiveness" indicates that differences at the school level contribute significantly towards variation in student outcomes; however, less is known about the effectiveness of schooling in low- and middle-income countries (LMICs). This paper addresses this gap using quantitative analysis of data from two…

In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…
