Policy guidelines of the Education Quality and Accountability Office (EQAO) state that accommodations and participation decisions on the Ontario Secondary School Literacy Test (OSSLT) do not threaten validity. However, these issues are contentious in American large-scale testing. New approaches integrate test access, administration, accommodation and participation within a unified fairness and validity construct. The current study, based on demographic and outcome data for the entire population of OSSLT-eligible students from 2006 to 2009, demonstrates changing patterns in accommodations and participation decisions across schools and years. In particular, English language learners are found to be considerably underrepresented among students receiving special needs accommodations. This has implications for the valid interpretation and fair use of test scores. Recommendations are proposed for improving fairness, consistency, and validity in administering accommodations and participation.

The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement. The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers’ attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden. The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole. The teachers use the tests in their instruction and they are a part of their planning. The advantages mentioned are the possibilities of showing off good examples, making the curriculum concrete, prepare the students for the test and get guidelines and support in assessment and grading. The teachers in the survey don’t consider the tests giving a full image of the abilities of a student nor do they consider the tests themselves relevant for the student’s learning. The result also shows a certain variation in the attitude of the teachers. Teachers, who have worked the longest period of time, more than 20 years, are those with the best attitude towards the test and their ability to contribute to increased goal attainment and equivalent assessment. Teachers who have worked the shortest period of time are the most skeptical to the positive effects of the tests. The teachers generally consider the tests contributing to equivalent assessment to some degree, but have the least positive stance toward the ability of the tests leading to improved quality meaning increased learning and goal attainment.

In the first essay, I assess the effect of indoor air quality (IAQ) in school buildings on student test performance and attendance rates. Results indicate that performance on standardized tests significantly improves while attendance rates are unresponsive to improvements in IAQ. The improvement in math scores ranges from 0.102 - 0.189 standard deviations per $500,000 spent on IAQ-related renovations and is 35% - 50% greater than the improvement in reading scores. For the same budget, results suggest that the improvement in math scores following IAQ-related renovations is several times larger than the improvement associated with class size reductions. In the second essay, I examine the responsiveness of the daily labor supply of fishermen to transitory variations in the daily wage using data from the Florida spiny lobster fishery. The applicability of this research is both narrow and general. Understanding this relationship is key to determining the effectiveness of landing fees as a means to regulate fisheries. Tracing out the labor supply curve is also fundamental to labor economics and policy. I find that the wage elasticity of labor supply (participation) is positive and statistically different from zero, with a point estimate of 0.967. This suggests an upward slopping labor supply curve and refutes the notion of reference dependent preferences. In the third essay, I examine the bias associated with ignoring the multi-species aspect of labor supply decisions in spatially explicit bioeconomic fishery models. Using a complete 15-year panel of all fishing trips made by fishermen possessing a Florida spiny lobster license, including non-lobster trips, I show that the simplifying assumption of a dichotomous choice structure at the first node (i.e. participate in the target fishery or not) is not innocuous and that predicted participation rates can change substantially with the addition of another species as an outside alternative in the first decision node. / text

This thesis investigates the role of classmates in the academic achievement of an individual student. I propose a new strategy to identify ability spillovers and combine this strategy with a unique data set to estimate peer effects in education. Using this innovative approach, I quantify the average effect of peers on own academic achievement in middle school and analyze heterogeneity of own response to peers along ability and gender lines. In Chapter 1, I provide a comprehensive empirical analysis of linear-in-means model of peer interactions and estimate the effect of the average quality of peers on academic progress of six-graders in Ontario public schools. I provide convincing evidence of the validity of my identification strategy and show that the average quality of classmates measured by their lagged test scores matters for individual academic achievement. I find positive, large and significant ability spillovers from peers in the same classroom. To reconcile the broad spectrum of peer effect's estimates in the literature, I also investigate the impact of peers in the same school and grade. I show that once a peer group is aggregated to a grade or class level, the effect attenuates towards zero. In Chapter 2, I relax the main assumption of linear-in-means model and compare alternative models of peer interactions with the empirical results from the first chapter. My findings imply that all students unambiguously benefit from the presence of high achieving peers. At the same time, academic progress of high-achievers does not suffer from the presence of low-achieving classmates. This finding provides important policy implications for ability grouping of students in schools. With the help of a policy experiment I demonstrate that spreading out high ability students across classrooms is an efficient strategy to increase the achievement level of every student. In the third chapter, I introduce gender dimension into the analysis of peer effects and investigate the role of class gender composition on individual academic achievement. I employ two different identification strategies and find that large share of girls in a class facilitates academic progress of both boys and girls. While he average quality of girls is one of the determinants of own achievement, peer-to-peer interactions and improved discipline in a classroom, when more girls are present, also play an important role.

This research project deals with the effects of standardized achievement tests on elementary-school mathematics. It contains a review of current literature dealing with the decline in mathematics achievement, mathematics assessment, concept development, and the effects of standardized testing. A survey was conducted in seven elementary schools throughout Clay County, Florida. The purpose of the survey was to assess teachers' perceptions of how preparation for the major annual standardized achievement test affects the pacing, sequence, and presentation of their mathematics curricula. Eighty-six teachers from grades one, three, and five completed a limited response questionnaire. The results indicate that a majority of elementary school teachers try to prepare their students for the standardized achievement test by covering all testable skills by testing time. However, most teachers feel that preparation for this test has a negative impact on their mathematics programs. This implies that the mathematics education of our students may be suffering due to the emphasis on preparing for a standardized achievement test.

Standardized tests are being administered to young children in greater numbers in recent years than ever before. Many more important educational decisions about children are being based on the results of these tests. This practice continues to escalate despite early childhood professional organizations' calls for a ban of standardized testing for children eight years of age and younger. Many early childhood educators have become dissatisfied with multiple-choice testing as a measure of student learning and are increasingly using various forms of alternative assessment to replace the more traditional testing formats. Teachers seem to be caught in the middle of the controversy between standardized testing and alternative assessment. This research examined what early childhood educators in one north Texas school district believe about assessment of young children and what assessment methods they report using in their classrooms, as well as factors which influence those beliefs and practices. The sample for this study was 84 teachers who taught prekindergarten through third grade. An eight-page questionnaire provided quantitative data and interviews and the researcher's journal provided qualitative data.

In this study, the associations of socioeconomic variables with reading test scores in grade 4 (PIRLS) and with math and science test scores in grades 4 and 8 (TIMSS) were examined across 28 OECD countries. This study adds to the current knowledge base by integrating measures of income inequality, which have been used in a few studies involving test scores, with other socioeconomic variables of interest. Bivariate correlations show that certain socioeconomic measures have stronger relationships with test score inequality than with average test scores: income inequality, gender inequality, and adolescent fertility rates all have significant relationships with test score inequality in reading, math, and science. There are also strong intercorrelations among these three socioeconomic variables. Income inequality is significantly associated with average science test scores in grades 4 and 8, while adolescent fertility rates hold significant relationships with average math and science test scores in both grades. Intercorrelations among the variables show that people who live in a country with high income inequality, and are at the lower end of that country’s income distribution, struggle in ways that people in countries with low income inequality do not. Health insurance and access to health care, paid maternity leave, and preschool education are easier to obtain in countries with lower income inequality. Examination of individual countries gives additional insight into the important role of income inequality. Slovenia, for example, has a relatively low GDP per capita but enjoys good test scores, perhaps because of its low income inequality. Finland, another country with low income inequality, attains PIRLS and TIMSS test scores that are among the highest in the world, in part because of social services that have the effect of further reducing income inequality. The U.S. is something of a puzzle because it has relatively high scores despite substantial inequality. Based on the results of this study and other current research, it seems likely that the U.S. could reduce test score inequality by providing targeted supports to low-income families, effectively reducing income inequality. Such supports may include: 1) installing wraparound services within school settings for low-income families; and 2) substantially expanding preschool access, especially among 3-year-olds.

The number of standardized achievement tests that students in the United States are required to take has increased significantly during the past decade. Researchers have found that test anxiety is often a problem related to the increase in testing. This correlational study investigated the relationship between anxiety levels of 50 4th grade students and their standardized test scores. Test anxiety questionnaires and pulse rates were used as a measure of the anxiety level of each of the 4th grade students just before the standardized test was administered, and standardized test scores were used as a measure of academic performance. The data were analyzed using 2 separate Pearson correlations. The first determined the relationship between students' responses on a test anxiety questionnaire and their academic test scores; the second correlation determined the relationship between students' pulse rates and their test scores. The results indicated a significant relationship between the students' levels of test anxiety as measured by pulse rate and performance on the New York State Standardized Science test, but no significant relationship between students' levels of anxiety as measured by the questionnaire. The findings of this study are important to school administrators, teachers, and parents because they could illuminate how test anxiety may impair students' academic performance on standardized tests and thereby mask their true abilities. This study has important implications for positive social change by providing research-based findings that could lead to the development of test anxiety prevention strategies at the local site.

There is a perceived crisis concerning public education in the United States. This has led to an increase in the use of standardized tests for the purpose of measuring school effectiveness. However, the use of standardized tests for this purpose is problematic. Among these problems is the concern that standardized tests may not measure what parents believe are the most important attributes of an effective school. Unfortunately, there is little in the way of empirical evidence regarding parent beliefs in this area. The purpose of this research was to answer the following four questions. 1. What do parents of school-aged children in Utah feel are the most important attributes of an effective school? 2. Are there statistical and practical differences between levels of respondents' association with public schools and their responses to question #1? 3. Are there statistical and practical differences between levels of respondents' level of education and their responses to question #1? 4. Are there statistical and practical significant differences between respondents' gender and their responses to research question #1? A mail survey of 800 randomly selected Utah parents of school-aged children was conducted to address these questions. To answer research question #1, the method of paired comparisons was used to derive a parent ranking of eight attributes of an effective school. To answer research questions #2, #3, and #4, a chi-square analysis of association was conducted. The practical significance of these results was assessed through the calculation of the effect size w. In total, 199 usable surveys were returned. Results indicated that parents believed that providing students with a balanced curriculum that encourages a wide range of learning experiences and providing students with the skills necessary to become a productive and useful citizen were more important attributes of an effective school than providing students with a good understanding of basic academic skills. This result is important because it indicates parent support for two attributes of an effective school-wide range of learning experiences and skills to become a productive and useful citizen-that are difficult to measure through the use of standardized tests.
