Mathematics is traditionally taught using direct instruction, which has been found to engender negative affective responses towards the subject, including anxiety and low self-efficacy (Borko et al., 1992; Mischo & Maas, 2013). Direct instruction places authority on the instructor and involves teaching students about mathematics instead of…

Missing data is a common challenge to any researcher in almost any field of research. In particular, human participants in research do not always respond or return for assessments leaving the researcher to rely on missing data methods. The most common methods (i.e., Multiple Imputation and Full Information Maximum Likelihood) assume that the…

The effectiveness of the student conduct approaches of the mixed method model, a mixture of restorative justice and traditional sanctioning, and traditional sanctioning, known as the "model code," in student learning at historically Black colleges and universities (HBCUs) has been largely unexamined in existing literature. This…

Bayesian approach is becoming increasingly important as it provides many advantages in dealing with complex data. However, there is no well-defined model selection criterion or index in a Bayesian context. To address the challenges, new indices are needed. The goal of this study is to propose new model selection indices and to investigate their…

The concept of integration appears in many different scientific fields, and students' understanding of and ability to use the definite integral in applications is important to success in their STEM (science, technology, engineering, and mathematics) classes. One of the first types of application problems that students encounter is finding the…

A Prolog program consists of a set of facts and rules rather than imperative statements, commonly used in most other programming languages. Therefore, the Prolog language is used to encode logic, from which the inference engine deduces logical conclusions. In this article, we argue that the use of the Prolog language can be useful to help students…

A qualitative sugar identification laboratory was adapted from a hands-on experiment to a virtual "choose your own adventure" experience where students select virtual experiments to conduct on samples of known and unknown carbohydrates. Students select positive and negative controls for each qualitative test and compare results from the…

The switch to online instruction during the COVID-19 pandemic forced educators to adapt hands-on environmental engineering experiments to a remote curriculum previously conducted in a laboratory using expensive analytical instruments (>$2000 per device). Here, we describe how we developed a low-cost (<$200) aerosol sensor platform as a…

For most students, completing practice problems is an essential prerequisite for success in organic chemistry courses. Practice work, however, is sometimes perceived to be easier than or even not related to the types of chemistry that students see in assessments and "real-world" science. This negative view may contribute to a reduced…

Parents and politicians feel it is their duty to assert control over the information within school libraries. According to Joshua Spilka, a high school junior, book banning has affected no one more than students and school librarians. Students find that the people who are supposed to advocate for them, parents and guardians, are often working…

Social media is a popular method for recruiting research participants and especially during the current pandemic. Researchers are increasingly using platforms like Facebook and Twitter to engage with participant groups, either to collect data directly (by posting links to online surveys) or to recruit participants for further research activity (to…

In this paper, we introduce novel instructional approaches to engage students in using modelling with data to motivate and teach differential equations. Specifically, we introduce a pedagogical framework that will execute instructional modules to teach different solution techniques for differential equations through repositories and notebook…

Attendance at preschool represents an important transition, as it is often here that children have their first experience with unfamiliar adults. In this context, several factors can affect children's adjustment. Two important protective factors are the attachment relationship with the teacher and the level of executive functions. We investigate…

While research suggests that social emotional competencies (SECs) influence students' disciplinary outcomes, less is known of their potential to explain racial disparities or grade level differences in those outcomes. This study used survey and administrative data from 30,494 students in grades 3-12 to examine the degree to which SECs were related…

This study explores the professional development (PD) of rural teachers in China based on their relationship with "left-behind" children, guided by two research questions: 1) How do rural teachers describe their relationship with left-behind children? and 2) How do rural teachers perceive the influence of their relationship with…
