In this article, the author describes the "Be your own groundhog" project in her grades 9-12 Earth and environmental sciences courses, in which students use citizen science databases to research the physical changes that signal the arrival of spring. This project starts with a simple question, "When will spring spring?" This goes beyond the…

The recreational fishing activity presented in this article provides a hands-on, problem-based experience for students; it unites biology, math, economics, environmental policy, and population dynamics concepts. In addition, the activity allows students to shape environmental policy in a realistic setting and evaluate their peers' work. By…

In their research, scientists generate, test, and modify scientific models. These models can be shared with others and demonstrate a scientist's understanding of how the natural world works. Similarly, students can generate and modify models to gain a better understanding of the content, process, and nature of science (Kenyon, Schwarz, and Hug…

It's that time of year again, when avoiding the flu is on everyone's mind. As we brace ourselves for possible flu outbreaks, the need to understand biological issues related to this virus becomes clear. Through modeling, the lesson presented in this article helps students understand how the influenza virus (or flu) evolves and how flu vaccines are…

Educators and educational researchers alike are discovering that inductive methods--in which learners start with specific observations, problems, or cases and infer general laws from these instances--are more effective when higher-order thinking is the primary goal (Yadav et al. 2007). For decades, the case-study method has been widely used in law…

"A Tale of Four Electrons" is a creative writing assignment used with 10th-grade Honors Chemistry students. The project helps students consolidate their learning about bonding--an important unifying theme in chemistry--and answers questions such as (1) How are ionic, metallic, and covalent bonds related? (2) How do variations in electron…

Recent press coverage of the decrease in worldwide honeybee population (Kaplan 2010) has significantly increased public awareness of its ecological and economic importance. In addition, honeybees' social nature, novel method of gender determination, distinctive caste system, and behaviorally and chemically based language make them immediately…

Since 1995, the population of English language learners (ELLs) in the United States has increased by an astonishing 57% (Maxwell 2009). Though ELLs come from many different backgrounds, they share the common challenge of learning English while responding to academic content demands. Part I of this two-part article provides key strategies every…

Despite the burgeoning numbers of English language learners (ELLs) in our schools, many science teachers have little training in meeting their specialized needs. By the year 2010, it is estimated that 40% of K-12 classrooms in the United States will contain nonnative English speakers with varying levels of proficiency (Thomas and Collier 2002).…

Teaching new biology concepts to ninth graders can be tough, and teaching students with disabilities even tougher--but we are accountable for "all" students. These authors used a cooperative learning strategy called "Collaborative Strategic Reading" in an inclusive ninth-grade biology class to see whether they could "hook" students and, at the…

Research indicates that increased parental involvement has a positive impact on student achievement, especially among Hispanic students (Zarate 2007; NSTA 2010). This author helped science teachers at Falfurrias High School in Falfurrias, Texas, implement Family Science events, which were held three times a semester and attended by high school…

The National Science Education Standards are designed to provide a vision of scientific literacy for "all" students--regardless of age, race, ethnic background, English-language proficiency, socioeconomic status, disability, or giftedness. One of the most powerful strategies in science instruction--which aligns with the Standards--is the use of…

Have you ever bought a computer program that you thought would be great for your struggling students, only to find that it did not work on your school computers, or that your students found it difficult to use? Selecting science software for students with learning and other disabilities can be a challenge. This Idea Bank provides a list of…

We all have misconceptions about the world in which we live--how it works, how we interact with it, how it changes, and the reasons behind those changes. These misunderstandings are personal notions we create to make meaning of our surroundings. Often, these misunderstandings go unchallenged for a lifetime. This article addresses how these…

Conceptual change instruction recognizes that students bring personal, or naive, conceptions to the classroom, which they use to explain their world, interpret situations, and create meaning (Driver et al. 2007). But what happens when students' personal conceptions are inconsistent with experts' views of scientific knowledge? Even after direct…
