The real time PCR (qPCR) method provides a powerful method to assess levels of particular species of DNA. When combined with reverse transcription (RT-qPCR) it is the predominate technique to measure expression of gene transcripts. While this approach is very powerful, particular care must be taken in the design of the primers to facilitate…

This paper describes a reading assignment that resulted in students completing 80-90% of the assigned reading in a content-heavy science course taught in a flipped format. Students reported almost unanimously that the assignment was valuable in helping them learn the material, and a majority reported that other professors should adopt a similar…

Digital media assignments empower students to become co-creators of knowledge rather than passive consumers of content. The Internet explosion and the affordability of digital technologies and devices such as smartphones, tablets and action cameras have created opportunities to use digital media in the classroom. This article aims to present an…

Online formative assessment is still challenging although it is getting an increased attention as a significant tool for diagnosing and analysing students' motivation and achievement in various education domains. This research examines the effects of an online formative assessment tool (OFAT) about science motivation and achievement in second-year…

Active learning yields better learning outcomes than traditional, lecture-based teaching. Common approaches in large lecture courses are activating elements during the lectures and warm-up activities using online learning environments. However, implementing warm-up exercises, on which students work on by themselves makes formative feedback…

Pencasts are videos of problem solving with narration by the problem solver. Pedagogically, students can create pencasts to illustrate their own problem solving to the instructor or to their peers. Pencasts have implications for teaching at multiple levels from elementary grades through university courses. In this article, we describe the use of…

Learner-Generated Digital Media (LGDM) in tertiary science education focuses on research skills, inquiry, active learning, teamwork, and collaboration. LGDM across disciplines is under-theorised, under-researched, and only in its early development. This paper evaluates the research in the field of LGDM in tertiary science education. The literature…

This article describes the use of peer review in a writing project involving upper-level chemistry students in a chemical literature course, with the goal of improving student performance in meeting information literacy outcomes. Students were asked to find articles on a topic of their choice over the course of a semester and assemble the results…

Previous research on problem diagrams suggested that including a supportive diagram, one that does not provide necessary problem solving information, may bring little, or even negative, benefit to students' problem solving success. We tested the usefulness of problem diagrams on 12 different physics problems (6A/B experiments) in our massive open…

This case study reports the instructional development, impact, and lessons learned regarding the use of Facebook as an educational tool within a large enrollment Biology class at Spelman College (Atlanta, GA). We describe the use of this social networking site to (a) engage students in active scientific discussions, (b) build community within the…

This article describes the conversion of a lecture-based molecular biology course into an active learning environment in a studio classroom. Specific assignments and activities are provided as examples. The goal of these activities is to involve students in collaborative learning, teach them how to participate in the learning process, and give…

This work describes efforts to incorporate and evaluate the use of a YouTube writing assignment in large lecture classes to personalize learning and improve conceptual understanding of chemistry through peer- and self-explanation strategies. Although writing assignments can be a method to incorporate peer- and self-explanation strategies, this…

The objective of this study was to develop an online report writing activity that was a constructive and cooperative learning process for a course on traditional general physics experiments. Wiki, a CMC authoring tool, was used to construct the writing platform. Fifty-eight undergraduate students (33 men and 25 women), working in randomly assigned…

Constructing concept sketches (diagrams annotated with short captions in which students demonstrate their understanding of form, process, and interactions) provides a new and different way to teach Earth surface processes and assess the depth of student learning. During a semester-long course in Geomorphology, we used concept sketches as an…

Calibrated Peer Review™ (CPR), a web-based instructional tool developed as part of the National Science Foundation reform initiatives in undergraduate science education, allows instructors to incorporate multiple writing assignments in large courses without overwhelming the instructor. This study reports successful implementation of CPR in a…
