It is common for high school physics teachers to comment on the challenges they face in supporting students' graph drawing skills, knowing their importance for the study of physics. This paper suggests a novel and alternative way to support students to develop their graph drawing skills as well as teach them about sound, frequency, and amplitude.…

Khan Academy (KA) is one of the world's most popular open educational resources (OER), with more than 57 million registered users and 15 million monthly site visits as of May 2016. It is popular with students seeking additional resources for their math studies, and gaming features (in the form of points, badges, and missions) add to its appeal. As…

The chemistry laboratory can be a daunting place for first year university students, especially those entering one for the first time with little or no prior laboratory experience. Increasing financial constraints placed on secondary schools has restricted the ability to provide rich laboratory experiences for students before entering tertiary…

Technique-centered biochemistry or molecular biology undergraduate laboratory curricula do not offer significant opportunities for thoughtful, in-depth exploration of the science to foster investigative learning. To demonstrate inclusion of inquiry-driven laboratory experiments into the undergraduate biochemistry and molecular biology curricula, a…

Use of flipped learning environments, where content is delivered online outside of class and class time features student-centered activities, is an increasingly popular way to facilitate active learning. The success of classroom activities, however, depends on students' willingness to complete the out-of-class work and come to class well prepared.…

Researchers have raised concerns about teachers' ability to embed nature of science (NOS) in their science instruction, a complicated situation that is certainly impacted by the availability of adequate resources to assist K-12 science teachers. In light of the implementation of the ideas from the "Framework for K-12 Science Education"…

Through Preschool and Foundation Level, children are confident in their knowledge about rocks. Five- to six-year-olds have firm ideas on what they consider rocks are and where they might be found (Preston, 2018). With the exception of children who are avid rock collectors, such knowledge usually comprises general, inconsistent ideas formed from…

Mathematical reasoning with algebraic and geometric representations is essential for success in upperdivision and graduate-level physics courses. Complex algebra requires student to fluently move between algebraic and geometric representations. By designing a task for middle-division physics students to translate a geometric representation to…

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 focus of this article is to expand María del Mar Aragón, José Antonio Acevedo-Díaz and Antonio García-Carmona's paper "Prospective Biology teachers' understanding of the nature of science through an analysis of the historical case of Semmelweis and childbed fever" by focusing on the discussion about teaching non-epistemic aspects of…

This article presents a qualitative study of the understanding of various epistemic and non-epistemic aspects of the nature of science (NOS), based on analysis of the historical case of Semmelweis and childbed fever. To this aim, an activity was designed which consisted of: (1) reading of a narrative of the case without instruction and discussion…

This article concerns a lacuna in chemistry students' reasoning about chemical bonding. Although chemistry students are familiar with the charges that make up the atom--both positive and negative--they refer only to the attraction between unlike charges. Specifically, they ignore the repulsion between the positive nuclei. We named this disregard…

In this qualitative study, we examined the process of active learning from the perspective of undergraduate students in a high-enrollment introductory biology class. Eight students participated in a series of five interviews throughout the semester that examined their experiences during and after class. Grades were collected for each student at…

Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Recent educational research emphasizes the importance of personal social cognitive beliefs and metacognitive knowledge and skills for achievement in science as well as retention in the field. In this project, a mandatory evening tutorial program was developed to provide direct instruction in metacognitive skills for first year students enrolled in…
