A high-performance liquid chromatography experiment to determine the concentration of caffeine and vitamin B6 in sports energy drinks has been developed. This laboratory activity, which is appropriate for an upper-level instrumental analysis course, illustrates the standard addition method and simultaneous determination of two species. (Contains 1…

A primary goal of university instruction is the students' demonstration of improved, highly developed critical thinking (CT) skills. However, how do faculty encourage CT and its potential concomitant increase in student workload without negatively impacting student perceptions of the course? In this investigation, an advanced biology course is…

Academic writing at advanced levels is the most important way of demonstrating one's expertise in a discipline. Developing this kind of competence is especially a challenging effort for students in foreign language contexts. Many factors may be involved in determining why some students are more and some are less motivated in writing successful,…

Peer Instruction (PI) is an active learning pedagogical technique. PI lectures present students with a series of multiple-choice questions, which they respond to both individually and in groups. PI has been widely successful in the physical sciences and, recently, has been successfully adopted by computer science instructors in lower-division,…

Small and medium-sized businesses are generally considered to be a key driving force in national economies. In comparison with other countries, the percentage of nascent entrepreneurs in Germany is small. This has been attributed to a lack of entrepreneurial awareness, which can be created and developed in schools and higher education…

This study investigates students' individual patterns of adherence to a norm for creating and assessing definitions in an undergraduate real analysis classroom. Our findings indicate that, though all students understood the expectation to define, students differed in their individual adherence to the norm depending upon their perception of the…

This paper was intended to examine teacher's corrective feedback and student's preferences in an advanced writing course. The study was conducted using a questionnaire as the instrument and 15 MA TEFL students from Ilam state university in Iran as the participants. The students were asked to prioritize among a list of ten aspects of error…

We describe specific curricular decisions employed at Butler University that have resulted in student achievement in the actuarial science major. The paper includes a discussion of how these decisions might be applied in the context of a new actuarial program.

Despite the growing popularity of dual-credit courses as a college readiness strategy, numerous reviews of the literature have noted a number of important limitations of the research on the effects of dual-credit on student postsecondary outcomes. This study addressed these gaps in the literature by estimating the impact of dual-credit courses on…

Between 1990 and 2012, the percentage of 13-year-olds (most of whom are 8th graders) taking algebra more than doubled, from 15% to 34% (National Center for Education Statistics, 2013). Yet recent education policy changes suggest that this movement to encourage algebra-taking in 8th grade has begun to reverse course. Existing research suggests that…

We derived an index of high school academic rigor by optimizing the prediction of first-year college GPA based on high school courses taken, grades, and indicators of advanced coursework. Using a large data set (n~108,000) and nominal parameterization of high school course outcomes, the high school academic rigor (HSAR) index capitalizes on…

Advisory committees of mathematics consider abstract algebra as an essential component of the mathematical preparation of secondary teachers, yet preservice teachers find it challenging to connect the topics addressed in this advanced course with the high school algebra they must someday teach. This study analyzed the mathematical content…

The central aim of standardized exit exams is to motivate students and teachers to work harder on critical subject matters and thus increase student achievement. However, the effects of the implementation of central exams on student motivation have not been analyzed in a longitudinal section until now. In the present study, the consequences of…

Surveys in 1995, 2000, 2005, and 2010 investigated teaching and assessment methods in different undergraduate courses. In this article, the authors offer basic results from the 2010 survey. "Chalk and talk" remains the dominant teaching style, but there were drops in mean (although not median) values for those pedagogies and some growth in the use…

This article describes a three-year study assessing change in critical thinking demonstrated in essays written for regular class assignments. A rubric was designed and scorers trained to assess critical thinking holistically without knowledge of the writing prompt or author's status. The longitudinal improvement in scores earned by freshmen over…
