Background: Nanotechnology, a multidisciplinary field with increasing societal importance, demands for an increase in research abilities and capacities. Yet, nanoscience and nanotechnology (NST) are largely inaccessible to K-12 students. This situation demands efforts in research towards bringing NST learning into K-12 classrooms. Purpose: The…

The problem of practice being explored in this work was first identified at a suburban middle school in Massachusetts, where the assessment scores of students with learning disabilities were significantly lower than those of peers not on Individualized Education Plans. The collaboration between general education science teachers and special…

In the present study, we first examined the formality and use of academic language in students' scientific explanations in the form of written claim, written evidence, and written reasoning (CER). Middle school students constructed explanations within an intelligent tutoring system after completing a virtual science inquiry investigation. Results…

Many national policy documents underscore the importance of 21st century skills, including critical thinking. In parallel, recent American frameworks for K-12 Science education call for the development of critical thinking skills in science, also referred to as science inquiry skills/practices. Assessment of these skills is necessary, as indicated…

The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used…

We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

"If someone were traveling to our area for the first time during this time of year, what would you tell them to bring to wear? Why?" This question was used to engage students in a guided-inquiry unit about how climate differs from weather. In this lesson, students explored local and national data sets to give "travelers" advice…

Thirteen years ago, Minnesota was a state with no academic standards in mathematics and science and what some observers said was a mixed record in grounding students in crucial academic content, such as number skills and algebra. Since then, the state has set clear guidelines for schools in both subjects, and it also appears to have tuned up what…

Almost every time the results of an international test of student achievement are released to the world, the reaction among the American public and policymakers is like that of a parent whose child just brought home a disappointing report card. Elected officials and academic experts question where U.S. students fell short: Was it their curriculum,…

Guided by a new framework, the NAEP science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts related to properties and changes of matter, forms…

Teaching and assessing both content and 21st century skills are critical for student academic success and success in the workplace. In the "Highlights from TIMSS 2007" report, released in December of 2008 by the National Center for Education Statistics, Institute of Education Sciences, data shows that while 4th- and 8th-grade students in…

A representative sample of 122,000 eighth-graders participated in the 2011 National Assessment of Educational Progress (NAEP) science assessment, which is designed to measure students' knowledge and abilities in the areas of physical science, life science, and Earth and space sciences. This report covers the overall results, achievement level…

Guided by a new framework, the National Assessment of Educational Progress (NAEP) science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts…

Between 1994 and 2003, employment in science, technology, engineering and math (STEM) fields grew by a remarkable 23 percent, compared with 17 percent in non-STEM fields, according to federal data. The Bureau of Labor Statistics predicts continued strong growth in STEM job openings through 2014, with emphasis on life sciences, environmental…

In 1990, the National Assessment of Educational Progress (NAEP) included a Trial State Assessment (TSA); for the first time in the NAEP's history, voluntary state-by-state assessments were made. The sample was designed to represent the 8th grade public school population in a state or territory. In 1996, 44 states, the District of Columbia, Guam,…
