Assessments and student expectations can drive learning: students selectively study and learn the content and skills they believe critical to passing an exam in a given subject. Evaluating the nature of assessments in undergraduate science education can, therefore, provide substantial insight into student learning. We characterized and compared…

In a middle school classroom, the science of fluidics was introduced using the rig. Afterwards the students were able to make informed choices about using air or water as the medium inside their syringes. The three kits available through the NFPA were explored, reverse-engineered, discussed, and analyzed as a lead-in to the in-house culminating…

This paper reports case studies of five Chinese secondary physics teachers' beliefs and instructional decisions in relation to inquiry-based teaching (IBT). It is part of a larger study intended to explore Chinese secondary physics teachers' beliefs and the ways in which their beliefs influence their classroom practices in the context of the…

Achievement in science is a national concern, and graduating students who are college and career ready is a national imperative. In this study, we examine student achievement on the ACT science test as a high school transitioned from teaching biology, chemistry and physics with a teacher-centric pedagogy (the traditional instructional context) to…

In this paper we investigate how student disengagement relates to two performance metrics in a spoken dialog computer tutoring corpus, both when disengagement is measured through manual annotation by a trained human judge, and also when disengagement is measured through automatic annotation by the system based on a machine learning model. First,…

Purpose: The purpose of this study was to examine differences between boys and girls in their performance on STEM related AP exams. Specifically, gender differences were examined for the following STEM related AP exams: Calculus AB, Calculus BC, Physics B, Physics C: Electricity and Magnetism, Physics C: Mechanics, Chemistry, and Computer Science…

The purpose of this study was to examine the confidence levels that community college students have in transferring basic math skills to science classes, as well as any factors that influence their confidence levels. This study was conducted with 196 students at a community college in central Mississippi. The study was conducted during the month…

The use of science classroom discourse analysis as a way to gain a better understanding of various student cognitive outcomes has a rich history in Science Education in general and Physics Education Research (PER) in particular. When students talk to each other in a collaborative peer instruction environment, such as in the CLASP classes…

English textbooks are widely used in every discipline in the majority of colleges and universities in Taiwan. To prepare college students for their future careers, it is necessary they be given systematic training and practice in reading these books. However, due to time constraints, most content teachers focus on the delivery of content rather…

The existence of gender-STEM (science, technology, engineering, and mathematics) stereotypes has been repeatedly documented. This article examines physics teachers' gender bias in grading and the influence of teaching experience in Switzerland, Austria, and Germany. In a 2?×?2 between-subjects design, with years of teaching experience included as…

This case study examines the role of playful talk in negotiating the "how" of collaborative group work in a 6th-grade science classroom. Here we develop and test a Vygotsky-derived hypothesis that postulates playful talk as a mechanism for identity exploration and group status negotiation. Our findings indicate that students utilized the…

We investigated the effect of modeling and visualization resources on upper-division, undergraduate and graduate students' performance on an open-ended assessment of their understanding of physical hydrology. The students were enrolled in one of five sections of a physical hydrology course. In two of the sections, students completed homework…

The purpose of this study was to determine teachers' reasons for choosing the profession of teaching and their level of job satisfaction and to investigate the effects of certain variables on their job satisfaction. The research data were collected via a questionnaire form to determine the demographic backgrounds of the participants and a Job…

Academic year 2009-10 produced more astronomy bachelor's than in any other time in US history. The 382 astronomy physics bachelor's degrees earned in the class of 2010 represent a 19% increase from the previous class and an increase of 89% from a decade earlier. The number of astronomy PhDs conferred has remained at around 150 for the last 3…

The natural-language tutorial dialogue system that the authors are developing will allow them to focus on the nature of interactivity during tutoring as a malleable factor. Specifically, it will serve as a research platform for studies that manipulate the frequency and types of verbal alignment processes that take place during tutoring, such as…
