This updated third edition of "Curriculum Planning and Instructional Design for Gifted Learners": (1) Is a guide to designing curriculum for the gifted at any level of learning and in any subject area; (2) Addresses the need to differentiate at all levels in the design process; (3) Shows how to customize curriculum for advanced learners;…

The authors' school's second-grade science curriculum has always focused on trees and their role in the ecosystem during the first half of the year. Curricular goals have largely emphasized what students ought to "know" by the end of the semester, such as identifying the parts of a tree, describing the process of photosynthesis, and…

Everyday occurrences with evaporation are so ordinary that adults may not realize that children wonder about them and create explanations about what happens to water as wet objects dry. The process of evaporation is not visible, making it hard for young children to understand. Because they like to look for clues and participate in group…

There are many ways to share a collection of data and students' thinking about that data. Explaining the results of science inquiry is important--working scientists and amateurs both contribute information to the body of scientific knowledge. Students can collect data about an activity that is already happening in a classroom (e.g., the qualities…

Categorizing organisms as living or nonliving things may seem to be intuitive by nature. Yet, it is regulated by scientific criteria. Students come to school with rules already in place. Their categorizing criteria have already been influenced by their personal experiences, also known as observations and inferences. They believe that all things…

It is important to help young children make connections between events in their lives and science concepts in preschool classrooms, so introducing basic meteorology ideas offer a great opportunity to make weather connections and awaken scientific curiosity (Spiropoulou, Kostopoulos, and Jacovides 1999). Therefore, this article presents a science…

It is important for students to be exposed to the concept of osmotic pressure. Understanding this concept lays the foundation for deeper discussions that lead to more theoretical aspects of water movement associated with the concepts of free energy, water potential, osmotic potential, pressure potential, and osmotic adjustment. The concept of…

You'll gain plenty of weather resources from this month's issue (temperature concepts, weather instruments, the water cycle/evaporation). You can use that information with these outdoor seasonal connections.

Too often, students enter our classrooms with insufficient knowledge of physical science. As a result, they have a difficult time understanding content in texts, lectures, and laboratory activities. This lack of background knowledge can have an impact on their ability to ask questions and wonder--both key components of inquiry. In this article,…

A main reason for using the history of science in classroom instruction is its utility in promoting students' understanding of the nature of science (NOS). As indicated in such documents as the "National Science Education Standards," it is important to help students develop their understanding of NOS so that they will become more critical…

Amongst the challenges that elementary teachers may often face as they introduce their students to science is the need to maintain a solid understanding of the many scientific concepts and details themselves. This indispensible resource, intended for pre- and in-service elementary school teachers, provides concise and comprehensible explanation of…

How can a science teacher find professional development (PD) opportunities that are meaningful, coherent, and sustained that will foster teacher and student learning? The authors believe that science teachers can and should be savvy consumers of PD--seeking out learning experiences that are designed with a few key features in mind. The purpose of…

Individual recommendation plans (IRP) for student teaching practice were co-constructed with two methods students based on the select application of National Science Teachers Association's National Standards for Science Teacher Preparation. Methods students completed a resume, an interview on pedagogical preferences, and a learning styles survey…

This longitudinal study of middle school science teachers explored the relationship between effective science instruction, as defined by the National Science Education Standards (NRC in National science education standards. National Academy Press, Washington, DC, 1996), and student achievement in science. Eleven teachers participated in a three…

Almost three decades ago, the birth of Louise Brown in England marked the beginning of the "in vitro" fertilization (IVF) era. IVF is done to overcome infertility problems that some couples experience. Sperm and eggs are collected and fertilized in the lab. ("In vitro" means "in glass" and is used to refer to…
