In genetics education, symbols are used for alleles to visualize them and to explain probabilities of progeny and inheritance paradigms. In this study, we identified symbol systems used in genetics textbooks and the justifications provided for changes in the symbol systems. Moreover, we wanted to understand how students justify the use of…

The form and function of a collaborative assessment known as a "Buddy Quiz" is presented. The assessment is conducted in three successive phases over a contiguous 45-60 min class period. A portion of each quiz is completed in collaboration with one or two peers and a portion is completed without collaboration. The quiz is primarily…

The conception of Global Learning Communities (GLCs) was researched to discover potential benefits of the use of online technologies that facilitated communication and scientific data sharing outside of the normal classroom setting. 1,419 students in 635 student groups began the instructional unit. Students represented the classrooms of 33…

The School Quality or Student Success (SQ/SS) indicator was one of the most talked about and biggest decisions that fell to the states in drafting their new ESSA accountability plans. This memo summarizes the chosen SQ/SS measures for each state, DC, and Puerto Rico. The most common SQ/SS measures among the states are: (1) Chronic Absenteeism (37…

More schools in the United States have begun teaching physics to ninth-graders, but there continues to be limited evidence that such a change benefits students. Many arguments in favor of Physics First and the inverted sequence of physics-chemistry-biology are based more on the intellectual logic of the sequence than on measured outcomes. Paul…

This study examined science textbooks over time to better understand the "science content" expectations that the U.S. educational system deems appropriate for 8th and 9th grade science students. The study attempted to answer the questions: (1) What specific science content has been presented via the textbook from 1952 to 2008? (2) Within…

Spurred by a succession of reports pointing to the importance of algebra as a gateway to college, educators and policymakers embraced "algebra for all" policies in the 1990s and began working to ensure that students take the subject by 9th grade or earlier. A trickle of studies suggests that in practice, though, getting all students past…

The country's technological edge is receding, and the problem cannot be solved simply by flooding the workforce with more engineers and scientists. This comes as little surprise to administrators at the nation's community colleges. In 2007, the National Academy of Engineering, National Academy of Science, and the Institute of Medicine responded to…

The purpose of this mixed-method study was to investigate the changes in high school students' perceptions of fluency with innovative technologies (IT) and the levels of students' scientific inquiry abilities as a result of engaging students in long-term scientific research projects focusing on community-based environmental issues. Over a span of…

This First Look presents findings from the base-year survey of the newly launched High School Longitudinal Study of 2009 (HSLS:09), the first round of a study that will follow a ninth-grade cohort through high school and into their postsecondary years. HSLS:09 is the fifth in a series of National Center for Education Statistics (NCES) high school…

The focus of this First Look report is on base-year contextual data from the High School Longitudinal Study of 2009 (HSLS:09). This First Look is intended as a companion to the report, "High School Longitudinal Study of 2009 (HSLS:09): A First Look at Fall 2009 Ninth-Graders (NCES 2011327)" (ED521115), which focuses on the mathematics…

Compares the achievement in science for ninth grade students in China and the United States. Reveals a small difference between the two groups and presents a rationale for the comparison. Contains 31 references. (DDR)

Most comparative studies about China were challenged by many sinologists and educators for not grounding on representative samples. This research is mainly based on a Chinese data base collected from a random sample of more than 10,000 9th-grade students in the Second International Association for the Evaluation of Educational Achievement (IEA)…

English language learners (ELLs) often find themselves marginalized with respect to learning mathematics in U.S. schools due, in part, to language barriers and gaps in prerequisite math knowledge and skills. The goal of this study was to use Sen's (1980, 1992, 1999) capabilities approach model as a lens through which to analyze the relationship…

Using the national data from high school transcript studies conducted from 1982 to 2005, this special analysis addresses the following questions related to students' coursetaking patterns and trends during this period: (1) What do states require and what do schools offer for coursework?; (2) How many course credits do students earn by high school…
