In this article, the authors proposed a distillation and matching model (DMM) that describes how evidence-based treatment operations can be conceptualized at a lower order level of analysis than simply by their manuals. Also referred to as the "common elements" approach, this model demonstrates the feasibility of coding and identifying the…

This article reports results from a study focused on teachers' knowledge of students' understanding of core algebraic concepts. In particular, the study examined middle school mathematics teachers' knowledge of students' understanding of the equal sign and variable, and students' success applying their understanding of these concepts. Interview…

Evolution is at the center of the biological sciences and is therefore a required topic for virtually every college biology student. Over the past year, the authors have been building a new simulation software package called EvoBeaker to teach college-level evolutionary biology through simulated experiments. They have built both micro and…

The idea for this project developed in a doctoral seminar taught by Caroline Helton, a white faculty member in voice at the University of Michigan. In a presentation on the performance practice of singing spirituals, Emery Stephens, an African American graduate student in the seminar, concluded by encouraging everyone in the room (all white with…

Most Americans are not very familiar with the first peoples of the Americas. Though some might argue that it is wholly unnecessary to have any knowledge about Native peoples, most would probably agree that some exposure to Native perspectives is a good thing for students. In this article, the author offers his perspective on the most important…

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week…

Multiple choice questions are a common method of assessing student understanding. In this article, the authors discuss and evaluate a student-focused collaborative learning strategy for working with such questions that results in greater student learning and allows instructors to better understand student thinking and ultimately to write better…

Using evidence from eye-tracking studies, Van Gompel, Pickering, Pearson, and Liversedge (2005) have argued against currently implemented constraint-based models of syntactic ambiguity resolution. The case against these competition models is based on a mismatch between reported patterns of reading data and the putative predictions of the models.…

Although researchers are exploring animals' capacity for monitoring their states of uncertainty, the use of some paradigms allows the criticism that animals map avoidance responses to error-causing stimuli not because of uncertainty monitored but because of feedback signals and stimulus aversion. The authors addressed this criticism with an…

Verleger, Jaskowski, Aydemir, van der Lubbe, and Groen (see record 2004-21166-002) and Lleras and Enns (see record 2004-21166-001) have argued that negative compatibility effects (NCEs) obtained with masked primes do not reflect self-inhibition processes in motor control. Instead, NCEs are assumed to reflect activation of the response opposite to…

"In his commentary to our paper on the use of knowledge, skill, and ability statements in developing credentialing examinations (Wang, Schnipke, & Witt, 2005 )," Dr. LaDuca set forth his concerns while commending our paper for providing helpful insights into the importance of careful delineation of KSAs. We believe that there is little substantive…

Physicists have known for some time that pendulum motion is a useful analogy for other physical processes. Chemists have played with the idea from time to time but the strength of the analogy between pendulum motion and chemical processes has only received prominent published recognition since about 1980, although there are details of the analogy…

Students' understanding of functions is a topic that has been researched extensively. In this qualitative study, five university students of varying mathematical backgrounds were interviewed to reveal strategies and misconceptions as they struggled with graphical and analytical tasks relating to sum functions. Weaker students are seen to rely…

"High stakes testing" is to be understood as testing with serious consequences for students, their teachers and their educational institutions. It plays a central role in holding teachers and educational institutions to account. In a recent article Randall Curren seeks to refute a number of philosophical arguments developed in my "The Limits of…

This article describes the central limit theorem (CLT) and its relation to analytical chemistry. The pedagogic rational, which argues for teaching the CLT in the analytical chemistry classroom, is discussed. Some analytical chemistry concepts that could be improved through an understanding of the CLT are also described. (Contains 2 figures.)
