The Monitoring the Future (MTF) study monitors historical and developmental changes in substance use prevalence among key subgroups of the general U.S. adolescent and adult population. The current study first devised and evaluated a cohort-specific pooled analysis weighing procedure for the MTF panel study that weighted back to the initial 12th grade samples. Following this, the cohort-specific weights were updated to age-specific weights in order to provide increased flexibility for a wide range of model specifications and to avoid the need to re-calculate a first half-sample respondent's final weight at a particular wave after the full cohort had completed that wave. The cohort-specific pooled analysis weights appear to result in an overall improvement in the degree to which the sociodemographic distributions of the initial 12th grade samples are retained, as well as likely producing slightly improved substance use estimates due to accounting for historical variation in panel sample selection and attrition over time. The updated age-specific pooled analysis weights continued to provide the benefits associated with the cohort-specific weights, but also brought increased flexibility for modeling both cohort- and age-specific research questions, and allowed all respondents' weights at each specific age to remain fixed across time.

We provide the first causal evidence of the returns to maternal educational curricula on offspring's health at birth. Educational programs that aim to deliver more general knowledge may potentially improve women's earning potential and maternal prenatal investment by increasing the portability of skills across occupations and improving women's ability to make informed decisions about fertility options and health behavior. We study the impacts of a comprehensive educational reform that postponed students' curriculum choices and integrated more general education into the high school system on infant health outcomes. Using a dose-response difference-in-differences (DiD) model research design applied to linked population registries, we find that the reform led to a significant reduction in the incidence of very low birth weight (less than 1,500 grams) and very preterm birth (less than 33 gestation weeks). Overall, the reform's positive effects on infant health at birth seem to be driven by increased mothers' labor market opportunities and better family planning, rather than increased ability to avoid risky behaviours or increased women's earnings via different occupational choices or assortative mating.

We provide evidence from a randomized controlled trial on the effectiveness of a novel, 100-percent online math tutoring program, targeted at secondary school students from highly disadvantaged neighborhoods. The intensive, eight-week-long program was delivered by qualified math teachers in groups of two students during after-school hours. The intervention significantly increased standardized test scores (+0.26 SD) and end-of-year math grades (+0.48 SD), while reducing the probability of repeating the school year. The intervention also raised aspirations, as well as self-reported effort at school.

Anti-scientific attitudes can impose substantial costs on societies. Can schools be an important agent in mitigating the propagation of such attitudes? This paper investigates the effect of the content of science education on anti-scientific attitudes, knowledge, and choices. The analysis exploits staggered reforms that reduce or expand the coverage of evolution theory in US state science education standards. I compare adjacent cohorts in models with state and cohort fixed effects and conduct fine-grained placebo tests to rule out scientific, religious and political confounders. There are three main results. First, expanded evolution coverage increases students' knowledge about evolution. Second, the reforms translate into greater evolution belief in adulthood, but do not crowd out religiosity or affect political attitudes. Third, the reforms affect high-stakes life decisions, namely the probability of working in life sciences.

In this paper, we use NWEA MAP test data to examine variation in students' achievement and growth during the pandemic across multiple dimensions. Consistent with prior evidence, we find that students' test scores in fall 2021, on average, were substantially below historic averages. Moreover, the average scores of students of color, students attending high poverty schools, and students in elementary school were more negatively impacted, and more so in math than reading. We present novel evidence on the distributions of test scores and growth in fall 2021 relative to pre-pandemic distributions, finding disproportionately larger declines for students with lower previous achievement levels across districts. However, between districts, there was considerable variation in the extent to which their fall 2021 achievement and growth distributions shifted from their historical distributions by subject, student subgroups, and baseline achievement levels. Therefore, accurately targeting students and choosing interventions for pandemic-related recovery will require careful assessment by districts of their students' achievement and growth in the 2021-22 school year (and into the future): assuming that students in a district reflect the national trends of achievement will often lead to incorrect conclusions about the degree to which they suffered pandemic-related learning losses and the amount of support they will need to recover.

This occasional paper presents national demographic subgroup data for the 1975-2021 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The study covers all major classes of illicit and licit psychoactive drugs for an array of population subgroups. The 2020 subgroup data presented here accompany the "Monitoring the Future National Survey Results on Drug Use: 1975-2021: Overview, Key Findings on Adolescent Drug Use" (see ED618240) and the "Monitoring the Future National Survey Results on Drug Use, 1975-2021, forthcoming: Volume I, Secondary School Students." The trends offered here in tabular and graphic forms cover demographic subgroups based on: (1) Gender; (2) College plans; (3) Region of the country; (4) Population density; (5) Education level of the parents (a proxy for socioeconomic level); and (6) Racial/ethnic identification. Detailed descriptions of the demographic categories are provided in the section starting on page 469 of this paper. The graphs and tables in this occasional paper present trend data for 8th-, 10th-, and 12th-grade respondents separately. Data for 12th grade begins with 1975, the first year in which a nationally representative sample of high school seniors was surveyed. Data for 8th and 10th grades begin with 1991, when the study's nationally representative annual surveys were expanded to include surveys of those lower grade levels.

This analysis uses the case of the Better Math Teaching Network (BMTN) to explore whether individuals participating in a networked improvement community (NIC) experienced common developmental trajectories on known dimensions of engagement. The analysis included quantitative data from annual network member surveys and qualitative data from annual member interviews. Evidence suggests potential developmental trajectories on three key dimensions of network participation: (1) learning how to engage in a network; (2) learning to use the tools of improvement science; and (3) learning to take up the theory of improvement. Additional findings show preliminary variations based on participant characteristics such as teaching tenure, whether they participated in the network with a colleague they knew prior to joining the network or with a school-based colleague, the context of their school, and how student centered they were at the outset of their participation.

This occasional paper presents subgroup findings from the Monitoring the Future (MTF) study on levels of, and trends in, the use of a number of substances for nationally representative samples of high school graduates ages 19-30, "Monitoring the Future National Survey Results on Drug Use, 1975-2018. Volume II, College Students & Adults Ages 19-60" (see ED599071). The data have been gathered in a series of follow-up surveys of representative subsamples of high school seniors who were first surveyed in 12th grade as part of the MTF study. Data were first available for the 19-22 age group in 1980 and for the older age groups in subsequent years as the early cohorts progressed in age, as the tables and figures in this occasional paper indicate. The subgroup trends shown in the current occasional paper complement the last section of Chapter 5 (Trends in Drug Use in Early and Middle Adulthood) of that monograph by presenting the trend data for young adult subgroups in both graphic and tabular form. The results are described and discussed in Chapter 5, but the extensive set of tables and figures is provided here for the reader who wishes to view the figures and the underlying numerical values in tabular form. Three demographic dimensions are differentiated: gender, region of the country, and population density. Gender includes trends for males and females; region describes trends for each of the four major regions defined by the U.S. Census; and population density differentiates trends for five levels of community size. The Table of Contents and List of Figures in this occasional paper contain links to the content and figures. Following each figure is a table giving the numerical values associated with each trend line in that figure. [For the 1988-2019 Monitoring the Future Occasional Paper, see ED608244.]

Education has faced unprecedented disruption during the COVID-19 pandemic; evidence about the subsequent effect on children is of crucial importance. We use data from an oral reading fluency (ORF) assessment--a rapid assessment taking only a few minutes that measures a fundamental reading skill--to examine COVID's effects on children's reading ability during the pandemic in more than 100 U.S. school districts. Effects were pronounced, especially for Grades 2-3, but distinct across spring and fall 2020. While many students were not assessed in spring 2020, those who were seemed to have experienced relatively limited or no growth in ORF relative to gains observed in other years. In fall 2020, a far more representative set of students was observed. For those students, growth was more pronounced and seemed to approach levels observed in previous years. Worryingly, there were also signs of stratification such that students in lower-achieving districts may be falling further behind. However, at the level of individual students, those who were struggling with reading prior to the pandemic were not disproportionately impacted in terms of ORF growth. This data offers an important window onto how a foundational skill is being affected by COVID-19 and this approach can be used in the future to examine how student abilities recover as education enters a post-COVID paradigm.

A growing body of evidence suggests that vocationally focused programs of study substantially improve high-school completion and longer-run economic success. However, the corresponding recommendations to expand vocational programs may have unintended, negative consequences for low-income, academically successful students (i.e., the "missing one offs") who have the capacity and motivation to attend highly selective universities. This study contributes to our understanding of these issues by examining an innovative, college-preparatory program targeted to academically successful Chilean students attending vocational high schools serving lower-income communities. This program (Escuela Desarrollo de Talentos or EDT) provides academic and social-emotional supports aligned with admission to selective universities. We examine the educational effects of EDT participation using a fuzzy regression-discontinuity design based on its eligibility rules. We find that the EDT program did not increase the probability of graduating from high school but did increase performance in math courses. We also find corresponding evidence suggesting that EDT participation increased math performance on college entrance exams and shifted students away from further postsecondary vocational training and towards matriculation at elite universities.

Using discontinuities within the Swedish SAT [scholastic aptitude test] system, we show that additional admission opportunities causally affect college choices. Students with high-educated parents change timing, colleges, and fields in ways that appear consistent with basic economic theory. In contrast, very talented students with low-educated parents react to higher scores by increasing overall enrolment and graduation rates. Remarkably, most of this effect arises from increased participation in college programs and institutions that they could have attended even with a lower score. This suggests that students with low-educated parents face behavioral barriers even in a setting where colleges are tuition-free, student grants are universal and application systems are simple.

Disrupted schooling can heavily impact the amount of education pupils receive. Starting in early June of 2011 a huge social outburst of pupil protests, walk-outs, riots and school occupations called the Chilean Winter caused more than 8 million of lost school days. Within a matter of days, riots reached the national level with hundreds of thousands of pupils occupying schools, marching on the streets and demanding better education. Exploiting a police report on occupied schools in Santiago, I assess the effect of reduced school attendance in the context of schools occupations on pupils' cognitive achievement. This paper investigates whether or not there is a causal relationship between the protests and school occupations and the standardised test performance of those pupils whose schools were occupied.

England currently faces a shortage of teachers, in part due to declining retention. Research suggests that one important influence on teachers' decisions about whether to leave teaching is the quality of working conditions in their school. Understanding which specific aspects of working conditions have the strongest relationship with retention could therefore help improve the supply of teachers. This report uses data collected from a large sample of teachers in the Teaching and Learning International Survey (TALIS) 2018, linked to data from the School Workforce Census (SWC), to investigate how the quality of working conditions varies and how it influences both job satisfaction and whether teachers subsequently leave their school or the teaching profession overall. Prior analysis using the TALIS 2013 data investigated the relationships between school working conditions and teacher job satisfaction and desire to move school. The present research updates and extends that analysis. In particular, the new data affords the opportunity to compare working conditions across primary and secondary phases, model the relationship between working conditions and whether teachers are observed to actually leave their school or the profession, investigate the importance of school discipline, and compare changes in working conditions for lower secondary teachers over time.
