One of the concepts taught to science students is the use of hemocytometer. Students in microbiology, genetics, and anatomy and physiology (A&P) classes use the hemocytometer in a variety of activities. In microbiology and genetics classes, it is used to quantify yeast cells, while in A&P classes; students learn how to count blood cells. This…

Remember the time when all you had to do was memorize these five steps: ask a question, formulate a hypothesis, perform experiment, collect data, and draw conclusions? And you received full credit for defining the scientific method. Well, those days are gone. This article discusses why the "scientific method ain't what it used to be." (Contains 2…

Twin strategies of Institutes on the Teaching and Learning of Science and Mathematics and support for faculty through minigrants are shown to be effective in stimulating college science and mathematics faculty to modify their introductory courses to include more active learning strategies. The institutes were designed to provide faculty who are…

Inquiry-based instruction is gaining favor in college classrooms because it improves scientific skills as well as critical thinking. As we seek ways to improve science education, elementary school is increasingly becoming an embattled component because of decreased time spent on science during those years. The approach that elementary educators…

A journal-club-based class has been developed to promote active and cooperative learning and expose seniors in biochemistry and cellular molecular biology to recent research in the field. Besides giving oral presentations, students also write three papers: one discussing an article of their own choosing and two, discussing articles presented by…

In times of economic downturn, college enrollments often increase. Entering students may come from diverse educational backgrounds and bring variable skill sets. In this article, the authors describe a skills-focused course developed to ensure that transfer and nontraditional students returning to education are prepared to succeed in…

Forensic science education has evolved as an interdisciplinary science that includes medicine, chemistry, biology, and criminal justice. Therefore, multiple paths can lead to a career in forensic science. A formal education usually requires the student to attend a college or university to obtain a bachelor's or master's degree. In many cases,…

An interdisciplinary and context-driven course focused on global water issues was developed and taught at the college level. Students designed a semester-long research project, collected and analyzed data, and ultimately presented their results and conclusions to the larger community. As a result of the course, students' science literacy improved…

Creative exercises (CEs) are a form of assessment in which students are given a prompt and asked to write down as many distinct, correct, and relevant facts about the prompt as they can. Students receive credit for each fact that they include that is related to the prompt and distinct from the other facts they list. With CEs, students have an…

Preservice preparation courses for elementary teachers of science can provide opportunities to build pedagogical content knowledge. One common concern of preservice teachers is how to cope with a preplanned lesson that does not proceed as planned. Providing opportunities for preservice teachers to experience the unexpected actually immerses them…

Preservice elementary education students often do not have a good feel for the process of science. Many may be acquainted with the steps of the scientific method but have never been through the scientific process. An exercise was designed using temperature-logging iButtons (Thermochrons) to improve knowledge of and familiarity with the process of…

If a picture is worth a thousand words, think about how long it takes your students to read a thousand words. Case studies are effective and stimulating ways to teach a variety of subjects, including the biological sciences. In learning the details of a particular case, students develop skills in both deductive and inductive reasoning, hypothesis…

Diagrams and figures play a central role in science and science education. Research has indicated that, when presented and used properly in a classroom setting, these external representations can contribute to students' understanding of scientific concepts; however, it is apparent that students do not always use, understand, interpret, or value…

Despite years of formal education, approximately one-third of all undergraduate students still cannot explain the causes of the seasons. Student manipulation of a handheld model is one approach to teaching this concept; however, the large number of students in many introductory classes can dissuade instructors from utilizing this teaching…

This case study's primary objective is to describe the implementation of the electronic response system (clickers) in a small (N = 25) second-year physics course at a large public university and to draw attention of the science faculty who teach upper-level science courses to the potential benefits of this pedagogy. This pilot study discusses the…
