A new approach, termed the "scale factor method," is presented for solving a variety of stoichiometry problems. Students taught to solve mass-mass stoichiometry problems using this method found it more intuitive and had a higher rate of success than students using the traditional dimension analysis approach. The scale factor approach…

Science education has an important role to play in supporting our young people to meet the complex challenges of the modern age. Students need a curriculum that can prepare them to work collaboratively, competently and confidently to address the wicked "glocal" problems of our time. Rangatahi themselves recognise this - those involved in…

Everyone has problems, from the smallest ant competing for a food source to the largest elephant needing to cool down. Fortunately, organisms have structures that function to help them solve these problems. So when a group of fourth-grade students look for solutions to their problems, who do they turn to? A biological champion, of course! Plants…

Science and mathematics are becoming computational endeavors. This fact is reflected in the recently released Next Generation Science Standards and the decision to include "computational thinking" as a core scientific practice. With this addition, and the increased presence of computation in mathematics and scientific contexts, a new…

The vision for science education set forth in "A Framework for K-12 Science Education" (NRC 2012) makes it clear that for today's students to become the scientifically literate citizens of tomorrow their educational experiences must help them become mathematically proficient. "The focus here is on important practices, such as modeling, developing…

An emerging body of research suggests that a set of broad "21st century skills"--such as adaptability, complex communication skills, and the ability to solve non-routine problems--are valuable across a wide range of jobs in the national economy. However, the role of K-12 education in helping students learn these skills is a subject of current…

This National Aeronautics and Space Administration (NASA) document presents activities on the properties of galaxies for additional curriculum support. The activities presented in this document include: (1) "How Big Is the Universe"; (2) "Identifying Galaxies"; (3) "Classifying Galaxies Using Hubble's Fork Diagram"; (4) "Identifying Unusual…

This document is a guide for teaching and learning concerning inquiry education. It identifies scientific inquiry in correlation with the National Science Education Standards and discusses the various functions and strategies for assessment. Contents include: (1) Inquiry in Science and in Classrooms; (2) Inquiry in the National Science Education…

This brief report highlights findings from the two assessments in mathematics and three assessments in science conducted by the National Assessment of Educational Progress between 1969 and 1978. In mathematics, average scores declined during the mid-1970s, especially on problem solving. In science, students generally declined in knowledge, skills,…

This learning activities notebook presents creative, elementary- and secondary-level, standards-based learning activities for teachers by teachers. They include a November-December teaching almanac, mathematics activities, language arts activities, science activities, and social studies activities. A reproducible sheet presents a Santa Sightings…

There is consensus in the United States that schools are not succeeding. This paper presents recent research in mathematics, science, language arts, social studies, and the arts to discuss ways in which to improve instruction and learning in these areas. Featured topics include cooperative learning, problem solving, use of technology, whole…

Teachers' beliefs about science reform have an important effect on how science is taught. This article examines a kindergarten teacher's science curriculum as she seeks to implement five of Washington State's Essential Academic Learning Requirements (EALRs) for core concepts and principles of science. The authors examine factors that affect…

This summary report of the National Assessment of Educational Progress (NAEP) 1996 State Assessment Program in Science and Mathematics provides comparisons of average mathematics scale scores for Grades 4 and Grade 8 in public schools and comparisons of average science scale scores for Grade 8 in participating jurisdictions. Data is presented in a…

This report was drawn from the 1996 National Assessment of Educational Progress (NAEP) and describes the science performance of eighth grade students in North Carolina. It compares results for various groups of students within that population and examines the results for individual demographic groups as well as individual background questions. The…

This technical report on the National Association of Educational Progress (NAEP) 1996 State Assessment Program in Science provides an overview of the design, implementation and analysis of the educational assessment including details of sampling design, field administration, preliminary data analysis, and reporting of state results. This report…
