The ability to interpret and reason from Tree of Life diagrams is a key component of twenty-first century science literacy. This article reports on the authors' continued development of a multifaceted research-based curriculum--including an instructional booklet, lectures, laboratories and a field activity--to teach such tree thinking to biology…

Muelleman, Andrew W.; Glaser, Rainer E. – Journal of Chemical Education, 2018
Literacy requires reading comprehension, and fostering reading skills is an essential prerequisite to and a synergistic enabler of the development of writing skills. Reading comprehension in the chemical sciences not only consists of the understanding of text but also includes the reading and processing of data tables, schemes, and graphs. Thus,…

Chinni, Rosemarie C. – Journal of Chemical Education, 2012
This laboratory experiment introduces students to a different type of atomic spectroscopy: laser-induced breakdown spectroscopy (LIBS). LIBS uses a laser-generated spark to excite the sample; once excited, the elemental emission is spectrally resolved and detected. The students use LIBS to analyze a series of standard synthetic silicate samples…

Davis, Sarah – Voices from the Middle, 2012
In any content area, teachers have opportunities to help their students develop more robust vocabularies; however, many content area teachers "know relatively little about effective instructional practices for vocabulary development" (Fisher & Frey, 2008). This article offers content area teachers three examples of rich opportunities for word…

Grammer, Robert T. – American Biology Teacher, 2012
We propose a procedure for the assay of fermentation in yeast in microcentrifuge tubes that is simple and rapid, permitting assay replicates, descriptive statistics, and the preparation of line graphs that indicate reproducibility. Using regression and simple derivatives to determine initial velocities, we suggest methods to compare the effects of…

Euler, Manfred – Physics Education, 2013
A hands-on model of scanning tunnelling microscopy (STM) is presented. It uses near-field imaging with sound and computer assisted visualization to create acoustic mappings of resonator arrangements. Due to the (partial) analogy of matter and sound waves the images closely resemble STM scans of atoms. Moreover, the method can be extended to build…

Dopico, Eduardo; Linde, Ana R.; Garcia-Vazquez, Eva – Journal of Biological Education, 2014
Introducing research in undergraduate biology studies may contribute to creating research vocations and generate the idea that science may influence all aspects of common life. However, laboratory practices are too often disconnected from current investigations and rarely address real-life questions that are really interesting for students.…

Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with "business as usual." The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that…

Okebukola, Peter A.; Suwadu, Bugoma; Oladejo, Adekunle; Nyandwi, Ramadhani; Ademola, Ibukun; Okorie, Henry; Awaah, Fred – Journal of Chemical Education, 2020
This paper provides glimpses of transactions in chemistry classrooms in five African countries (Burundi, Ghana, Morocco, Nigeria, and Senegal) during the COVID-19 lockdown. Members of the secondary school community in the countries including teachers, students, and school managers were unprepared for the unprecedent demand in shift from a…

Geldenhuys, Elsje-Márie; Burger, Elsie Helena; van Helden, Paul David; Mole, Calvin Gerald; Kotzé, Sanet Henriët – Anatomical Sciences Education, 2016
An accurate knowledge of anatomy, especially natural variation within individuals, is of vital clinical importance. Cadaver dissection during anatomical training may be a valuable introduction to pathology for undergraduate students, which can contribute greatly to a successful medical career. The purpose of this study was to determine the extent…

Coles, S. J.; Mapp, L. K. – Journal of Chemical Education, 2016
An undergraduate practical exercise has been designed to provide hands-on, instrument-based experience of advanced characterization techniques. A research experience approach is taken, centered around the concept of solid-state polymorphism, which requires a detailed knowledge of molecular and crystal structure to be gained by advanced analytical…

Fonseca, Custódia S. C. – Journal of Chemical Education, 2016
Saccharin (1,2-benzisothiazole-3-one 1,1-dioxide) is an artificial sweetener used in the food industry. It is a cheap and easily available organic compound that may be used in organic chemistry laboratory classes for the synthesis of related heterocyclic compounds and as a derivatizing agent. In this work, saccharin is used as a starting material…

Rivera, Jennifer Hall – Open Learning, 2016
An increase in online education is causing science educators to evaluate student cognitive understanding after completing virtual, computer-simulated laboratories. Online education has demonstrated comparable learning gains when analysed to those of the traditional classroom, but research is mixed when reviewing students' ability to manipulate…

Nunn, John – Physics Education, 2016
This paper aims to enable schools to make their own low-cost temperature logging instrument and to learn something about its calibration in the process. This paper describes how a thermistor can be integrated into a simple potential divider circuit which is powered with the sound output of a computer and monitored by the microphone input. The…
