  TIMSS 1999 Benchmarking Science Report Chap5_1
The most striking difference among science curricula of the TIMSS 1999 countries in the eighth and earlier grades is that the sciences are taught as separate subjects in some countries and integrated to form a general science course in others.
Exhibit 5.1 shows how science instruction is organized in these grades in the TIMSS 1999 countries and Benchmarking jurisdictions.
Of the countries that taught science as separate subjects, most taught chemistry and physics as separate subjects by the eighth grade, while in separate-science Benchmarking jurisdictions these were taught together as physical science.

 Highlights of APA Science Directorate Activities - 1999
Plans are being developed to work with behavioral and social science departments and programs in colleges and universities throughout the country to infuse an element of public outreach and education into their efforts over the course of the academic year.
At its spring 1999 meeting, the CARE initiated a number of new projects, which focused on educating the public about the nature of nonhuman animal research, in general, and in psychology in particular.
The Science Directorate has continued to monitor the curriculum development of last year's award recipients and is pleased to announce that the universities-Bowling Green State University, Kansas State University, and University of Minnesota--offered their first courses this fall.

 October 8, 1999, Hour Two: Science in the Courtroom
Science often plays an important role in the courtroom -- DNA evidence, medical malpractice suits, and the like.
Once, the only test of science in the courtroom was whether or not the science was generally accepted by the scientific community.
The decision places the judge in a "gatekeeper" role, controlling what is accepted as "good science" in his or her courtroom.

 NAEP - Long-Term Trend Science 1999 Results
Although the average score in 1999 was higher than the average scores from 1977 through 1990, it remained lower than the average score in 1969.
A slight decline since 1992, however, resulted in an average score in 1999 that was similar to that in 1970.
Increases between 1982 and 1990, followed by relatively stable performance in the 1990s, resulted in an average score in 1999 that was higher than that in 1970.

 SCI-BYTES: Science in Singapore, 1999-2003
Singapore's world share of science and social-science papers over a recent five-year period, expressed as a percentage of papers in each of 21 fields in the Thomson Scientific database.
As the right-hand column indicates, the impact (or average citations per paper) of computer-science papers from Singapore was 18% below the average in the field during the five-year period (1.03 cites per paper for Singapore versus the world average of 1.26 citations), with an identical score recorded in engineering.
In agricultural sciences, Singapore-based authors contributed to only 104 Thomson-indexed papers, but at least a few of these reports, evidently, were very highly cited, giving the nation a score 48% above the world average.

In "Space: 1999" gravity is often modified by unknown forces.
Bergman reveals an even worse misconception of scientific principles in Space Brain when he states that the only two practical schemes for changing the Moon's course are "shockwaves and anti-gravity screens".
While the second is a made-up part of "Space: 1999" science, the first could not operate in the vacuum of space (the same shockwaves error is made in Collision Course and The A B Chrysalis).

In 1973, the scientists Harmon and Julesz published block portraits of Abraham Lincoln that were important in vision science (5).
Their "critical-band" explanation of the block-portrait effect implicitly assumes size invariance and thus predicts that face recognition requires a certain number of marks per face independent of face size (but they only tested the effect at one small size).
The author is in the Department of Psychology and the Center for Neural Science, New York University, New York, NY 10003, USA.

 NAEP - Long-Term Trend: Science 1999
Because the long-term trend assessment uses different instruments from those used in the main assessments, and because students are sampled by age for the long-term trend assessment rather than by grade as in the main assessments, it is not possible to compare results from the two assessment programs.
The  cognitive dimension assesses students' understanding of the nature of science within the context of both the content and cognitive dimensions.
In order to maintain the long-term trend in science, the National Assessment Governing Board (NAGB) determined in 2002 that technical studies were required to enable necessary changes to the design of the assessment and revisions to the item pool. For these reasons, science was not assessed in the 2003-2004 school year.

 1998-1999 Writing Science Sessions
Over a broad sweep of history, I think it may be useful to think about three things together: the object of the scientist's (or philosopher's) knowledge, the nature of that knowledge and the means of securing it, and the identity of the knower.
Arguing that the work of metaphor and narrative is simultaneously scientific and cultural work, I shall touch upon such issues as borders/boundaries and the possibility of translations in science, cognitive approaches to science and cultural studies of science, and problems of agency and change.
As science studies moved toward cultural studies, the question arose what the term "culture" in cultural studies of science meant, and what explanatory power it was supposed to have.

The Penn State Department of Mathematics has received a grant for a new National Science Foundation program titled "Vertical Integration of Research and Education in the Mathematical Sciences" (VIGRE).
"With this grant we aim to build on the department's rise to research prominence in recent years by broadening and unifying its existing educational initiatives to develop it into a premier center for training in the mathematical sciences at all levels," says Gary Mullen, head of the Department of Mathematics.
Burago and Ono are developing an extensive set of thought-provoking and challenging problems whose solutions do not require advanced mathematical skills, which they plan to use during regular small-group discussion sessions with the students to emphasize problem solving and the development of logical and mathematical thinking.

 STIA-102: Introduction to Environmental Science, Fall 1999
Environmental science has always been a science that integrates natural with social science because it studies natural systems not only to understand nature but also to understand human relationships with nature.
Global Warming, for example, is a central concern of environmental science, but to understand it fully requires understanding the history and science of natural climate change, the history of human-induced greenhouse gas emissions, and the models that predict climate change.
Moreover, environmental science has always been an applied science; thus we must also introduce the practical approaches for solving problems.
