Though statistics is covered in secondary-school curricula, it is usually limited to few lessons and mainly taught in a procedural approach. There seems to be a gap between the education of mathematics teachers and the demands on their practice. Learning statistics from a mathematical perspective does not qualify to teach the subject properly.…

In this paper, we make a qualitative analysis of didactic experiments performed with five 6 to 10-year-old children and five primary school teachers, starting from a structured game with probabilistic elements. The fundamental idea is to stimulate probabilistic thinking not only by playing a card game with decision making in uncertain situations,…

This study was prompted by the Arizona Department of Education's (ADE) interest in learning more about the progress of English learner students toward English proficiency in the early grades. The study examined, for the 2013/14 kindergarten cohort in Arizona, the English language proficiency of non-native English speaker students and their English…

With the rapid emergence of K-12 online learning platforms, a new era of education has been opened up. It is crucial to have a dropout warning framework to preemptively identify K-12 students who are at risk of dropping out of the online courses. Prior researchers have focused on predicting dropout in Massive Open Online Courses (MOOCs), which…

Few studies have been conducted to investigate typologies of perpetration and victimization of traditional and cyber bullying together to develop a risk profile by considering factors from different contexts. National data from the 2009-2010 Health Behavior in School-Aged Children study in the United States was utilized for these purposes. Four…

Office disciplinary referrals (ODRs) during students' first year of high school have been understudied despite research indicating they undermine graduation rates. Based on two cohorts of 9th grade students from one high school in one American Midwestern state, trends in ODRs were analysed in relation to students' and teachers' ratings of…

Communities develop social languages in which utterances take on culturally specific situated meanings. As physics students interact in their classroom, they can learn the broader physics community's social language by co-constructing meanings with their instructors. We provide an exposition of a systematic and productive use of idiosyncratic,…

The study determined the problem-solving performance and skills of prospective elementary teachers (PETs) in the Northern Philippines. Specifically, it defined the PETs' level of problem-solving performance in number sense, measurement, geometry, algebra, and probability; significant predictors of their problem-solving performance in terms of sex,…

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…

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…
