Districts now have access to a wealth of new information that can help target students with appropriate supports and bring focus and coherence to college readiness efforts. However, the abundance of data has brought its own challenges. Schools and school systems are often overwhelmed with the amount of data available. The capacity of districts to…

Visual data differs from visual information since it must be recorded, analyzed, and manipulated in some manner, whereas visual information is primarily sensory input. Our environment is constantly infused with visual inputs, and it is sometimes difficult to make sense of them or to determine how best to deal with them for instructional purposes…

Elementary students make great scientists. They are natural questioners and observers. Capitalizing on this natural curiosity and wonderment, the authors have developed a method of doing inquiry investigations with students that many teachers have found practical and user friendly. Their belief is that full inquiry lessons serve as a vital method…

The commentaries on my article contain a number of points with which I disagree but also several with which I agree. For example, I continue to believe that the existence of many cases in which between-person variability does not increase with age indicates that greater variance with increased age is not inevitable among healthy individuals up to…

Excitation of molecular iodine vapor with a green (543.4 nm) helium-neon laser produces a fluorescence spectrum that is well suited for the upper-level undergraduate physical chemistry laboratory. Application of standard evaluation techniques to the spectrum yields ground electronic-state molecular parameters in good agreement with literature…

Experimental data are analysed statistically to allow researchers to draw conclusions from a limited set of measurements. The hard fact is that researchers can never be certain that measurements from a sample will exactly reflect the properties of the entire group of possible candidates available to be studied (although using a sample is often the…

This qualitative study examined instructors' and students' perceptions of social relationship in distance learning. Interview and observational data were collected and analyzed to generate theories. Convenient sampling was used. Factors influencing a sense of distance were analyzed. Findings revealed greater difficulty establishing a social…

Our research addresses the role that context expertise plays when students compare data. We report findings from a study conducted in 3 countries: Australia, United States, and Thailand. In each country, six middle school students analyzed authentic data relating to selected students' areas of interest. We examined the data analysis processes and…

This study lies at an intersection between advancing educational data mining methods for detecting students' knowledge-in-action and the broader question of how conceptual and mathematical forms of knowing interact in exploring complex chemical systems. More specifically, it investigates students' inquiry actions in three computer-based models of…

Teachers can reflect on and analyze their classroom discourse to inform their instructional practice. When teachers try to do so however, they often face analytic difficulties, which include the data set (e.g., data input, data transformation, and utterances by unknown speakers), coding (e.g., coding complexity, reliability, and efficiency),…

Individuals and teams engaging in the scholarship of teaching and learning (SoTL) in multidisciplinary higher education settings must make decisions regarding choice of research methodology and methods. These decisions are guided by the research context and the goals of the inquiry. With reference to our own recent experiences investigating…

While problem solving as an instructional technique is widely advocated, educators are often challenged in effectively assessing student skill in this area. Students failing to solve a problem might fail in any of several aspects of the effort. The purpose of this research was to validate a scaffolded technique for assessing problem solving in…

While women now earn more bachelor's degrees than men in many parts of the world, large gender gaps persist in fields of study, and women remain underrepresented in the most prestigious institutions. This study updates and extends the literature on gender disparities in higher education by comparing the selectivity of the institutions where men…

Standardized tests are often designed to provide only a snapshot of test takers' knowledge, skills, or abilities at a single point in time. Sometimes, however, they are expected to serve more demanding functions, one of them is assessing change in knowledge, skills, or ability over time because of learning effects.The latter is the case for the…

In recent years, the much touted "difficult economic times" has resulted in a drastic reduction in arts and education funding in western capitalist nations (Fowles 2014; Henwood and Featherstone 2013; Murray and Erridge 2012; Smith 2013). Combined with this "age of austerity," schools have been subjected to decades of…
