How can critical and analytical thinking be improved so that they mimic real-life research and prepare students for university courses? The data sets obtained in students' experiments were used to encourage students to evaluate results, experiments, and published information critically. Examples show that students can learn to compare and defend ...

Global Positioning System (GPS) technology can be used to connect students to the natural world and improve their skills in observation, identification, and classification. Using GPS devices in the classroom increases student interest in science, encourages team-building skills, and improves biology content knowledge. Additionally, it helps educators meet the ISTE's ...

The way an animal moves from place to place can inform us about its life and environment. In this lesson, students examine the travel patterns of juvenile flatfishes in an estuary. The process of sampling bottom-dwelling fishes is explained, and data from a university-based marine science laboratory are evaluated. Students ...

We present a class discussion that took place in the second author's high school biology class. Working from video data that we transcribed, studied, and analyzed closely, we recount how the question "Is air matter?" posed at the beginning of a unit on photosynthesis led to student-driven inquiry and learning. ...

This article discusses a number of aspects of the nature of science that can be illustrated by considering the development of pangenesis, a principle proposed by Charles Darwin to describe the rules of inheritance, explain the source of new variation, and solve other natural history puzzles. Pangenesis--although false--can be used ...

Science requires the acquisition and analysis of empirical (sense-derived) data. Given the same physical objects or phenomena, the sense organs of all people do not respond equally to these stimuli, nor do their minds interpret sensory signals identically. Therefore, teachers should develop lectures on human sensory systems that include some ...

Teaching and learning animal anatomy has a long history in the biology classroom. As in many fields of biology, decades of experience teaching anatomy have led to the unofficial selection of model species. However, in some cases the model may not be the best choice for our students. Our struggle ...

I describe a design-based learning activity that utilizes the interdisciplinary content domain of biomimicry. Design-based learning requires student creativity and technological innovation to address novel science problems, characteristics of the nature of science not often addressed in schools. Alignment with national standards documents, protocols, and assessment recommendations are provided.

A key issue facing countries that are scaling up circumcision services is the technical difficulty, resources used, complications, and time to healing using open surgical techniques, the only methods approved by the major external funding agency, PEPFAR. The WHO has developed a framework for evaluating new circumcision devices, and two ...

Chromosome 22q11 aberrations substantially increase the risk for developing schizophrenia. Although micro-deletions in this region have been extensively investigated in different populations across the world, little is known of their prevalence in African subjects with schizophrenia. We screened 110 African Xhosa-speaking participants with schizophrenia for the presence of micro-deletions. As ...

Clinical and technical information imparted in most African languages involves inexact terminology and code switching, so it lacks the explanatory power characterised by the English language. African languages are absent in the tertiary science education environment and forums where African scientists could present scientific material in the medium of African ...
