Taking higher-level mathematics courses was generally associated with higher scores on the 2008 mathematics assessment at ages 13 and 17. For example, 13-year-olds who were enrolled in algebra classes scored higher on average than those enrolled in pre-algebra or regular mathematics. The percentages of 13-year-olds who reported taking pre-algebra or algebra in 2008 were higher than the percentages in 1986. The percentage of 17-year-olds who reported they had taken pre-calculus or calculus was higher in 2008 than in 1978, as was the percentage who had taken second-year algebra or trigonometry.

Research has shown that positive school climate is tied to high or improving attendance rates, test scores, promotion rates, and graduation rates. For example, a 2008 study examined seven years of longitudinal data on school leadership, parent and community ties, faculty quality, school safety and order, and instructional guidance. Schools that measured strong in most supports were 10 times as likely as schools with one or two strengths to show substantial gains in reading and mathematics.
The tidal forces due to the Moon and Sun generate very long waves which travel all around the ocean following the paths shown in co-tidal charts. The time when the crest of the wave reaches a port then gives the time of high water at the port. The time taken for the wave to travel around the ocean also means that there is a delay between the phases of the Moon and their effect on the tide. Springs and neaps in the North Sea, for example, are two days behind the new/full moon and first/third quarter moon. This is called the tide's age.[60][61]
In the Menai Strait, the results showed that the main Ci drop (spawning) events occurred during the third-quarter lunar phase, approaching neap tides, contrary to the result from Newell et al. (1982), who observed spawning during spring tides in North America. In North Wales, spring low water always occurs approximately during mid-morning (06:00) and late-afternoon (18:00), whereas neap low water occurs during midday and midnight. During neap tides, therefore, intertidal mussels are exposed to minimal (midnight) and maximal (midday) air temperatures each day. Yet, as stated above, no strong correlation was made between CI and daily thermal difference. Further investigations should be conducted on the hydrostatic pressure, which might cause stress on the feeding rate, for example, and so influence spawning (Battle 1931; Famme et al. 1986). Holt and Proctor (2003) showed that wind influences AT and SST in the Irish Sea; however, we found no strong correlation between the wind direction and strength of CI drops. Hence, our study suggests that spawning events of mussels in the Irish Sea are the results of more complex interactions between the organisms and their environment than solely a thermal shock, as seen in laboratory experiments. Further studies should work on the impact of food availability on mussel spawning events as it has been previously shown that the quality and abundance of phytoplankton can influence spawning patterns (Ram et al. 1996). 2ff7e9595c
