This article describes an interdisciplinary unit in which students explore biological "ice nucleation"--by particles that cause water to freeze at temperatures above -38°C--through the lens of the microbial ice nucleator "Pseudomonas syringae." Such This activity, which aligns with the "Next Generation Science…

Entirely predictable examinations are ones for which the questions are known in advance. Some assessments are designed this way, but in public examinations, predictability is subtler. Students familiarise themselves with the requirements broadly: likely topics that will come up, question formats and how to maximise their marks. If students can…

An undergraduate biochemistry laboratory experiment is described that utilizes free online bioinformatics tools along with readily available exonucleases to study the effects of base stacking and hydrogen bonding on the UV absorbance of DNA samples. UV absorbance of double-stranded DNA at the ?[subscript max] is decreased when the DNA bases are…

The phenomenon of industrial melanism (IM) became widely acknowledged as a well-documented example of natural selection largely as a result of H.B.D. Kettlewell's pioneering research on the subject in the early 1950s. It was quickly picked up by American biology textbooks starting in the early 1960s and became ubiquitous throughout the 1970s,…

This study investigated the effects of senior secondary school students' use of demo kits on their achievement in biology in Omu-Aran, Nigeria. The study utilized a quasi-experimental design and followed the non-randomized, non-equivalent pre-test and post-test control group of 2x2x3 factorial matrix. Data was obtained from four intact classes in…

The purpose of this quantitative study was to investigate the effects of using Twitter within the classroom on a secondary level and to determine whether the use of Twitter had statistically significant effects on student engagement and academic performance. Engagement is applied to student learning using Kearsley and Shneiderman's (1998)…

Transition metals play an important role in many biological processes, however, they are also toxic at high concentrations. Therefore, the uptake and efflux of these metals must be tightly regulated by the cell. Bacteria have evolved a variety of pathways and regulatory systems to monitor the presence and concentration of metals in the cellular…

This article is my reflection about the recent incident that took place in a sports ground in Pondicherry, India where a 17-year-old school boy collapsed and died in the sports ground after running only 80 meters in the 1500 meters race. The cause of death was an underlying cardiac cause that has manifested during the athletic event. The stress…

ASD research is at an important crossroads. The ASD diagnosis is important for assigning a child to early behavioral intervention and explaining a child's condition. But ASD research has not provided a diagnosis-specific medical treatment, or a consistent early predictor, or a unified life course. If the ASD diagnosis also lacks biological and…

History of science (HOS) plays a substantial role in the enhancement of rooted understanding in science teaching and learning. HOS of evolution and genetics has not been included in Vietnamese biology textbooks. This study aims to investigate the necessity of introducing evolution and genetics HOS into Vietnamese textbooks. A case study approach…

Background: Higher education outdoor studies programs retain a critical interest in student experiences as they seek to prepare citizens in a globalized, yet simultaneously neo-nationalist, world. Purpose: This research explored the impact of transculturality on the student experience of outdoor studies in the Transcultural European Outdoor…

The process of the language acquisition of children is reflected in two aspects; language structure and pragmatic functions. Data from "The Longtime Tracing Oral Corpus of Typical Development Children" (one child; 2,367 sentences) are analyzed. This study examines the child's sentence final particle (SFP) "ba", in which we…

Gender differences in reading development are a global phenomenon, with girls typically performing better than boys. Some studies have reported gender differences favouring girls in reading comprehension in South Africa, but little systematic evidence exists about gender differences in the cognitive-linguistic abilities that underlie reading…

A flipped-classroom environment generally strives to create more in-class time for activities that enhance student learning, while shifting some content delivery to outside the classroom through the use of short didactic videos. We compared a flipped-classroom setting with the traditional ("control") setting for an accelerated…

As well as providing a valuable and enjoyable experience for pupils, outdoor learning also enhances and contextualises learning in science by helping pupils understand science concepts. Teachers' lack of confidence in which aspects of the science curriculum they can actually teach outdoors deters them from venturing outside the classroom for…
