In this article, we assume that discursive language aspects of science education are highly intertwined with students' knowledge-building and meaning-making in science. In an empirical case study, we investigate secondary students' (ages 15 to 16) discursive language use during group interactions. The focus is on how students define and explain…

A chemistry course designed as an elective for chemistry, biochemistry, biology, and pharmaceutical science majors is described. The course is designed for second- through fourth-year undergraduate students. The prerequisite is first-semester, second-year undergraduate organic chemistry with the second semester of the organic sequence as a…

Students come into the classroom with a variety of background knowledge. Therefore, it is imperative that educators are able to help all students, regardless of their familiarity with the content. Since it can be challenging for some large enrollment classes to schedule recitation classes after lectures due to logistical constraints, this study…

Course-based undergraduate research experiences (CUREs) have been increasingly incorporated into science, technology, engineering, and mathematics (STEM) curricula, leading to greater inclusion of students in real-world STEM practices. Implicit within the definition of CUREs is the notion that generated research findings will have relevancy to one…

Teachers are eager for professional development on teaching evolution, especially if it includes direct ties to relevant curricula and detailed lesson plans. Howard Hughes Medical Institute's BioInteractive Online Professional Learning: Evolution course was developed to provide educators with free, in-depth, multimedia resources that highlight…

The aim of this paper was to investigate chemistry teachers' attitudes towards certain characteristics of the nature of science and history and philosophy of science, and the influence of those views on their teaching practice. The sample comprised 272 chemistry teachers. A questionnaire was used for data collection. Most teachers recognised some…

An introductory plant science lab offered by the Department of Agronomy & Horticulture at the University of Nebraska-Lincoln was adapted for online delivery. This paper describes the adjustments made for online delivery and examines students' perceptions of learning and engagement from surveys administered in both the in-person and online…

Academic vocabulary networks were examined in 3 elementary grades textbook programs (first through fifth grade) in 3 domains--science, mathematics, and social studies. Within each program, a given network consisted of a focal domain-specific academic word and the collection of words from all grades that overlapped in meaning with the focal word.…

Active learning pedagogical approaches and methodologies have been shown to increase undergraduate student success. Specifically, the flipped classroom approach pushes course content outside of the classroom, allowing for the focus of each class period to be centered on student-student interactions and reducing student cognitive load in comparison…

Controversies in science are an essential feature of scientific practice: defined here as current problems that are unresolved because there are no accepted procedures by which they can be resolved or there are differing assumptions that affect the interpretation of evidence. Although there has been much attention in science education literature…

The Next Generation Science Standards (NGSS) require teachers to think very carefully about the structure of lessons, which content must be taught to allow students to achieve NGSS expectations, and how content is delivered. With the standards' focus on three-dimensional learning and the use of relevant phenomena, most teachers are urged to make…

The washback effect is particularly relevant when it comes to high-stakes tests, such as university entrance exams. This article presents a research study performed with the aim of determining the current influence of these exams on the teaching of chemistry in upper secondary education. The study was based on a questionnaire distributed among…

This study investigated the effect of explicit nature of science (NOS) instruction and explicit argumentation instruction in socioscientific and scientific contexts, on students' NOS conceptions and their argumentation skills. Undergraduate students enrolled in two sections of a science content course were assigned into two groups: Socioscientific…

To address the problems of too specialized content and single teaching methods in general education courses of science and engineering in colleges and universities, this study tries to reform such general courses under the guidance of the "student-centered" concept. A general chemical education course, "Chemical Mysteries in Movie…

Using external representations (ERs) to foster content understanding in biology education has increased as they allow for the visualization of abstract biological phenomena. However, the extent to which students have visualization skills required to learn from ERs effectively remains an open question. The current quantitative quasi-experimental…
