Focusing on the equity aspect of proposals for making opportunity-to-learn standards integral to an accountability system, this article discusses conceptual issues surrounding determination of equal educational opportunity and explores ways that these issues manifest themselves in empirical formulations of opportunity to learn (OTL). Using two databases, OTL measures are developed according to three alternative conceptions of equality—the Libertarian, Liberal, and Democratic Liberal conceptions—and the influence of these conceptions on the information provided is compared. This examination shows the intimate relation between values on equality and measures of equality and brings these issues to the fore for discussion by educators and policymakers.

Mathematical Connection

Mathematical connection is the ability of mathematics to connect conceptual and procedural knowledge, use mathematics in other subjects, use mathematics in life activities. Mathematics is a difficult subject for students as well as chemical equilibrium material, because both lessons are abstract. Mathematical ability is a basic ability that students must master in Chemical Equilibrium. Determination of Equilibrium Assets (Kc and Kp) requires mathematical connection capabilities. The results obtained from the Chemical Equilibrium test given are still low with a percentage of 65% for the calculation of removal, 45% root shape and the ability to multiply and divide the decimal number to 67%. This is because learning mathematics and chemical equilibrium are difficult subjects so students are less interested.
