We report a series of experiments examining whether people ascribe knowledge for true beliefs based on probabilistic evidence. Participants were less likely to ascribe knowledge for beliefs based on probabilistic evidence than for beliefs based on perceptual evidence (Experiments 1 and 2A) or testimony providing causal information (Experiment 2B).…

This dissertation focuses on microeconomic topics in the fields of public, labor and education. Particularly, this dissertation evaluates state policies in higher education and develops a global measure for job quality. Chapter 1 studies how state merit aid programs affect undergraduate degrees earned in Science, Technology, Engineering and…

The impact of automatic promotion practice on students dropping out of Uganda's primary education was assessed using propensity score in difference in differences analysis technique. The analysis strategy was instrumental in addressing the selection bias problem, as well as biases arising from common trends over time, and permanent latent…

The public has more choices than ever when it comes to choosing media, which has led to gaps in knowledge across members of the public. Investigating motivational differences across demographic groups to pay attention to agriculture-related news could address knowledge gaps related to agriculture-related issues. The Elaboration Likelihood Model…

The influence of classroom context on the probability of being caught cheating is compared between face-to-face classes and online classes. A decision tree model assigned in the context of a management science class presents alternatives, including unethical choices, risks and rewards, and a decision facing a potential ethical dilemma. Part of the…

Stimuli that capture the central tendency of presented exemplars are often preferred--a phenomenon also known as the classic beauty-in-averageness effect. However, recent studies have shown that this effect can reverse under certain conditions. We propose that a key variable for such ugliness-in-averageness effects is the category structure of the…

This study analyzed the factors required for a researcher to become a professor in the humanities and sociology, science and engineering, medicine and biology, and general studies fields. The study focuses on research productivity and analyzes the impact of hiatuses in research production on promotion in universities as well as the time at which…

A quasi-experimental method and test-retest design were used to explore the impact of participating in test preparation, whether the impact of test preparation depends on the first ACT® score, and the impact of specific test preparation activities. Test preparation improved students' retest scores and this effect did not differ depending on…

We exploit differences in state special education funding systems based on special education enrollment ('bounty systems') or on total student enrollment ('census systems') to assess whether funding systems impact teacher turnover, teacher specialty, special education enrollment, state education spending, average class sizes, and teacher effort.…

To support efforts to improve students' college readiness and success, leaders at the Palau Ministry of Education and Palau Community College want to understand the experiences and background of Palau High School graduates who are better prepared for Palau Community College. This study identified the Palau High School academic preparation…

Data science has maintained its popularity for about 20 years. This study adopts a bottom-up approach to understand what data science is by analyzing the descriptions of courses offered by the data science programs in the United States. Through topic modeling, 14 topics are identified from the current curricula of 56 data science programs. These…

In adaptive learning systems, various models are employed to obtain the optimal learning schedule and review for a specific learner. Models of learning are used to estimate the learner's current recall probability by incorporating features or predictors proposed by psychological theory or empirically relevant to learners' performance. Logistic…

Teachers' content knowledge impacts on what they teach, how they teach and what their students learn. In order to check whether the prospective teachers in a rural South African university know the mathematics content they are expected to teach in the schools, at least at the same depth as their future students expected to attain, the research on…

This article reports on a pilot study that used concrete materials and TinkerPlots to support a Year 4 student's understanding of the big ideas of variation and expectation when investigating a random chance experiment using spinners.

This study measures the mathematical abilities high school graduates' in Bahrain. Mathematical abilities encompass conceptual understanding, procedural knowledge and problem-solving skills in the five content domains which are Number and Operations, Algebra, Geometry, Measurement, and Data Analysis and Probability. While procedural understanding…
