Early forms of state-run schooling emerged, which would later evolve into the "factory model" in the mid- to late-19th century. Its primary purpose is not intellectual development but rather social control by producing punctual, obedient, and efficient factory workers (Schraeger, 2018). The system is regimented with a standardized curriculum and scheduling that mimics the rhythms of industrial labor. At this time, science education is not formally part of most curricula. When present, it consists mainly of natural philosophy focused on memorization and recitation rather than hands-on investigation or contextual understanding (Klopfer & Aikenhead, 2022). This reflects a broader goal of disciplining the mind instead of cultivating inquiry and critical thinking. First-generation students, particularly from working-class backgrounds, are largely excluded from formal education. Schooling is intended to sort laborers, so access to advanced subjects like science is nonexistent for these populations.

The Common School Movement, led by Horace Mann, expanded free public education and promoted compulsory schooling. Schools are designed to standardize instruction and instill civic values. Early expansion of education benefits white, middle-class children. Working-class youth and immigrant families have limited access to secondary or higher education.

Universal public education expands to serve an industrializing nation. Industrialists support schooling as a way to standardize labor discipline and national identity. Education is structured around efficiency, repetition, and uniform curriculum delivery (Schraeger, 2018). Science enters urban curricula more widely, but is taught through rigid lectures and factual recall. There is minimal emphasis on experimentation, contextual application, or critical thinking (Klopfer & Aikenhead, 2022). Science was often framed as "natural philosophy," and was not yet a formalized subject in most secondary schools until after the Civil War. First-generation students, primarily children of laborers and immigrants, are steered into vocational training and denied access to advanced coursework. Higher education remains restricted to middle- and upper-class families.

Plessy v. Ferguson upholds “separate but equal,” legally codifying school segregation. This establishes inequitable access to educational resources for students of color. Segregated schools often lack science labs, up-to-date equipment, or trained science teachers, particularly in Black and Indigenous communities.

The U.S. education system formalizes the factory model through age grading, standardized testing, and curricular tracking. Schools increasingly sort students by perceived “ability” and social class, reinforcing structural inequities (Sleeter, 2015). Biology, chemistry, and physics are formally established as core science disciplines, but instruction remains heavily lecture-based, with a focus on content coverage rather than scientific practices (Klopfer & Aikenhead, 2022). Low-income and immigrant students are systematically tracked into non-college preparatory programs, preventing most first-generation students from pursuing higher education.

Brown v. Board of Education declares school segregation unconstitutional, marking a turning point in educational equity. Integration efforts slowly improve access to better-resourced science programs for previously segregated students, though implementation is uneven. Students of color begin gaining access to schools with more advanced science instruction, but systemic barriers persist.

The launch of Sputnik 1 triggers a nationwide panic over perceived educational shortcomings. The National Defense Education Act of 1958 channels major federal investment into math and science education to produce a technologically advanced workforce. Federal initiatives introduced inquiry-oriented curricula, such as the Biological Sciences Curriculum Study (BSCS) and the Chemical Education Material Study (CHEMS), which emerged in the early 1960s as a response to Sputnik. These reforms expand laboratory work and shift science teaching toward experimentation and reasoning (Klopfer & Aikenhead, 2022). However, implementation is concentrated in well-resourced schools. These reforms expand opportunity but deepen inequality. Schools serving working-class and immigrant communities often lack the funding, facilities, or teacher expertise to implement these curricula, leaving first-generation students with less rigorous science preparation.

The Civil Rights Movement brings attention to inequities in access to quality education. The Elementary and Secondary Education Act (ESEA) of 1965 increased federal involvement in public education to address disparities. Multicultural education frameworks begin to emerge. Science education begins to integrate the history of science and early Science-Technology-Society (STS) approaches, making content more relevant to everyday life and civic participation (Klopfer & Aikenhead, 2022). First-generation students, especially students of color and children of immigrants, benefit indirectly from expanded public education access but still face structural barriers in college readiness, especially in STEM preparation.

The Higher Education Act (HEA) establishes need-based financial aid to make college more accessible to low-income students. This marks the first major federal commitment to increasing access to higher education. Title I of the Elementary and Secondary Education Act (ESEA) specifically targeted funding to schools serving low-income communities. HEA lays the groundwork for TRIO programs, expanding access for first-generation students (Engle & Tinto, 2008). However, inequitable K–12 preparation continues to limit who benefits from these policies. Science courses serve as essential “gatekeeper” courses for postsecondary STEM pathways. Schools that offer advanced science sequences provide significant advantages for college-bound students (Klopfer & Aikenhead, 2022).

The Individuals with Disabilities Education Act, originally passed as the Education for All Handicapped Children Act (EHA) in 1975 and later reauthorized as IDEA, mandated free and appropriate education for students with disabilities (Marian High School, n.d.). Mainstreaming students into science classrooms prompts some diversification of the curriculum, but implementation and delivery remain inconsistent.

A new era of educational accountability emerges, marked by the release of A Nation at Risk (1983), which claimed U.S. schools are failing to prepare students for a competitive global economy (Marian High School, n.d.). In response, federal and state leaders pushed for uniform curriculum standards and standardized testing to ensure measurable outcomes. By the 1990s, this “standards-based reform” movement had shaped instructional priorities nationwide. While intended to improve quality and equity, it often reinforced resource disparities: schools with fewer funds face increased pressure to meet benchmarks without sufficient support. In science education, national frameworks began promoting inquiry-based teaching and the integration of technology, but high-stakes testing frequently narrowed classroom practices to rote content (Klopfer & Aikenhead, 2022). At the same time, multicultural and humanistic science education grew as a counter-movement, emphasizing the history and philosophy of science, socioscientific issues, and culturally relevant pedagogy to increase inclusivity in STEM fields. Despite expanded financial aid, many first-generation students remain underprepared for college due to continued inequities in access to advanced STEM coursework during high school (Engle & Tinto, 2008).

The No Child Left Behind Act (NCLB) of 2001 imposes strict test-based accountability and proficiency standards. While aiming to close achievement gaps, these policies narrow the curriculum and place disproportionate pressure on underfunded schools (Marian High School, n.d.). In science, the focus shifts toward standardized test preparation at the expense of laboratory work and inquiry (Klopfer & Aikenhead, 2022). This disproportionately affects schools already lacking science resources. Because many first-generation students attend under-resourced schools, they experience reduced access to high-quality instruction, widening opportunity gaps in college readiness.

2015-Present: Every Student Succeeds Act (ESSA) and the Rise of Next Generation Science Standards (NGSS)

# data[].attributes.body
The Every Student Succeeds Act (2015) replaces the punitive accountability model of the No Child Left Behind Act (2001), shifting much of the responsibility for educational accountability from the federal government to the states (Marian High School, n.d.). ESSA encouraged states to adopt more holistic measures of student success, including growth models, school climate, and postsecondary readiness. This allowed states to adopt more holistic definitions of student achievement beyond standardized test scores. Curriculum standards evolved to include 21st-century skills, global competencies, STEAM, environmental literacy, and social-emotional learning. During the same period, many states adopted the Next Generation Science Standards (NGSS), developed earlier in 2013. NGSS represents a paradigm shift in science education by emphasizing three-dimensional learning: disciplinary core ideas, science and engineering practices, and crosscutting concepts. This moves instruction away from rote memorization toward phenomena-based inquiry, engineering design, and real-world application of scientific reasoning. UDL (Universal Design for Learning) and culturally responsive teaching gain momentum as guiding frameworks for inclusive instruction. These shifts reflect an increasing recognition that schools must prepare students for a rapidly changing, technology-rich world. First-generation students benefit from broader accountability frameworks that allow schools to prioritize college and career readiness in more flexible ways. Programs such as bridge courses, early-college pathways, and STEM-focused mentoring aim to close preparation gaps (Engle & Tinto, 2008). At the postsecondary level, many colleges develop targeted first-generation initiatives, such as cohort-based learning communities, undergraduate research opportunities, and identity-affirming support services. Despite these gains, disparities in access to advanced high school science courses and college persistence remain, particularly for students in under-resourced communities.

The COVID-19 pandemic led to the largest and fastest shift to remote learning in U.S. history. Schools rapidly adopted digital platforms to maintain instruction, exposing deep inequities in technology access and student support. Educators integrated video conferencing, online learning management systems, and virtual labs at unprecedented scales. Science education faced unique challenges as hands-on lab work moved online. Teachers adapt by using simulations, at-home experiments, and digital lab notebooks. The pandemic accelerated the integration of digital literacy, blended learning models, and flexible instructional approaches, making technology a core component of teaching and learning rather than an add-on.

These changes amplified conversations about educational equity, student mental health, and the need for resilient learning systems. Post-pandemic recovery includes expanded one-to-one device programs, hybrid learning options, and professional development focused on technology integration and social-emotional learning.
