This study aims to develop a semiotic declarative knowledge model, which is a positive constructive behavior model that systematically facilitates understanding in order to ensure that learners think accurately and ask the right questions about a topic. The data used to develop the experimental model were obtained using four measurement tools…

As literature has reported, it is usual that university students in statistics courses, and even statistics teachers, interpret the confidence level associated with a confidence interval as the probability that the parameter value will be between the lower and upper interval limits. To confront this misconception, class activities have been…

School failure is substantive in Spain. The percentage of students that do not achieve the compulsory education diploma is around 20%. School failure is higher for students from lower socio-economic backgrounds. Students who "fail" cannot continue to post-compulsory education and, sooner or later, they have to leave formal education. The…

Over several years, Clark Pleasant Community School Corporation (CPCSC) schools have dedicated significant professional development hours and time to develop Essential Learnings (ELs) along with proficiency scales that could guide the content of classroom assessments used to determine student mastery. This report presents findings from statistical…

Building on common assumptions in theories of interest and mathematics education, this experimental study examined the effect of context personalization based on individual preferences, group personalization, and example choice with preselected popular examples on middle school students' situational interest and performance in mathematics.…

Because of their efficiency and ability to keep many other factors constant, twin studies have a special appeal for investigators. Just as with any teaching dataset, a "matched-sets" dataset used to illustrate a statistical model should be compelling, still relevant, and valid. Indeed, such a "model dataset" should meet the…

In this brief report, we examine whether students' (N = 230) willingness to help individuals in distress (altruism) would be augmented after viewing Secure Attachment Messages (SAM) during lecture in a college racism course. Students were presented with SAM in alternating weeks as part of the PowerPoint presentation slides. In each of the weeks,…

Objective: In community colleges, achieving competence in math is critical to students' timely progression through coursework and eventual educational success; yet, it remains unclear when the optimal timing to complete required math courses is in order to maximize the chance of completing a credential on time. This study examines the timing of…

The authors generated exact probability distributions for sample sizes up to 35 in each of three groups ("n" less than or equal to 105) and up to 10 in each of four groups ("n" less than or equal to 40). They compared the exact distributions to the chi-square, gamma, and beta approximations. The beta approximation was best in…

This study employs a uniquely multi-factorial, large-scale design to investigate baseline differences and the effects of a singular outdoor educational program on environmental attitudes, knowledge and behavior among primary and secondary school students educated in four different countries. Statistical modelling approaches employed country of…

This paper evaluates the effects of a high school curriculum reform on students' probability to enroll at university and to choose a Science, Technology, Engineering or Mathematics (STEM) major. The reform increased the difficulty of graduating from high school by increasing the instruction time in core subjects and by raising the graduation…

Guided by the interpersonal theory of suicide, this study examines the associations between gun carrying, bullying, and suicidal behaviors among high school students. Arizona Youth Risk Behavior Surveys were completed by 2,677 students in 2011; 9.0% reported suicide attempt in the past year, 5.5% carried a gun in the past 30 days, 8.5% were…

Community college transfer students often experience "transfer shock" at receiving four-year institutions, which includes a variety of academic, social, and institutional challenges associated with the first-year transfer experience. Research has demonstrated that first-year program interventions can facilitate the transition of…

The aim of this study is to evaluate learning and acquisition strategies used by second/foreign language learners. This study is a comparative investigation of learning and acquisition strategies of successful and less successful language learners. The main question of the study is to investigate if there is a relationship between the learners'…

Instructional technologies can be effective tools to foster student engagement, but university faculty may be reluctant to integrate innovative and evidence-based modern learning technologies into instruction. Based on Rogers' diffusion of innovation theory, this quantitative, nonexperimental, one-shot cross-sectional survey determined what…
