Resonance is a fundamental concept that is necessary for students' successful learning in organic chemistry. However, there is a need to know more about both (1) what students find important when describing resonance and (2) students' conceptual understanding. This research seeks to address this discrepancy by examining second-semester organic…

Background/Context: The emphasis on scientific practices articulated by the National Research Council framework and the Next Generation Science Standards requires significant pedagogical shifts for U.S. science teachers. Purpose/Objective/Research Question/Focus of Study: This study provides a rare window into the challenges and opportunities…

Understanding how chemistry teachers' interventions shape the reasoning that students express after a lesson is critical to support prospective and in-service teachers as they work with students' ideas in the classroom. In this qualitative research study, we analysed changes in the reasoning expressed by 10th grade students in a Chilean school in…

Problem solving and critical thinking are buzzwords used in defining general chemistry learning goals. Assessments including well-structured homework, quizzes, and exams are designed and incorporated to build these skills. Our research expanded upon the types of assessments and analyzed the effect of writing assignments for promoting problem…

At universities where introductory physics labs are taught by graduate student teaching assistants (TAs), there is a need for specialized professional development for those TAs. This paper presents a specific instantiation of a model for lab TA professional development that uses a combination of cognitive apprenticeship and expectancy-value…

This study investigated the value of using a scaffolded critique framework to promote two different types of writing--argumentative writing and explanatory writing--with different purposes within an argument-based inquiry approach known as the Science Writing Heuristic (SWH) approach. A quasi-experimental design with sixth and seventh grade…

The aim of this study is to investigate the impact of writing poems and keeping a journal as writing-to-learn activities on the academic achievement of students in teaching the Force and Motion unit in the Science class of fifth grade students in secondary school. Sample of the study consists of 50 students who study in the fifth grade of two…

We describe a pair of fully integrated courses designed to teach biology to non-majors in a manner that connects authentically to the liberal arts. The co-taught courses were organized around the question: What does it mean to be human? Students investigated this question in the context of three topics: dis/ability, race, and sex and gender. In…

We describe the structure of a writing-intensive, chemistry first year seminar designed to support a three week, research focused summer bridge program. Writing assignments in the seminar helped students understand their research activities, learn to conduct themselves as scientists, and reflect upon their lab work. The writing intensive seminar…

Non-major students taking science courses to fulfill degree requirements may show low interest in traditional lecture-based classrooms. While professors may try to incorporate hands-on activities to the classroom to foster enthusiasm, the development of a low-cost, low-hazard scienitfic activity that engages students can be challenging. Moreover,…

Capstone experiences are typically the culmination of an undergraduate program and allow students to integrate their content knowledge with communication and technical skills, many of which are desirable in the job market and graduate school. Learner-centered teaching fits well with a capstone course because it requires students to be more engaged…

Literacy remains an area of concern in early secondary education in Scotland (ages 12-14), with recent research suggesting a continued decline in attainment levels. As literacy underpins learning, interdisciplinary and collaborative approaches to teaching literacy are now being emphasized through the new Curriculum for Excellence that aims to…

The authors tested the predictions of a game theory model of plagiarism, using a test population of student papers submitted to an online plagiarism detection program, over five semesters in a non-majors biology course with multiple sections and high enrollment. Consistent with the model, as the probability of detection and the penalty if caught…

This study evaluated the effects of a short-term professional development session. Forty volunteer high school biology teachers were randomly assigned to one of two professional development conditions: (a) developing deep content knowledge (i.e., control condition) or (b) evaluating student errors and understanding in writing samples (i.e.,…

In this paper we studied the effectiveness of the writing criteria that are proposed to be applied during the construction of physics texts so that students with dyslexia do not confront reading difficulties with them. The effectiveness of the criteria has been assessed by the accomplishment of an investigation among students with and without…
