The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a "science kid" and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom.…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

In this research, we have explored the possible differences in students' performance in grade nine chemistry exams that could have been influenced by a different instructional approach in grade eight. We compared two groups of students: one group had received a transmissive propaedeutic approach in grade eight (especially related to the memorising…

This report leverages state educational agency data to explore the association between Alabama Science in Motion (ASIM) implementation and student outcomes. We conducted this study in Alabama to evaluate the potential of teacher implementation of ASIM lab activities to improve high school level student achievement in science. This study follows a…

The purpose of this quantitative, causal-comparative research study was to determine if and to what extent there were differences in chemistry end-of-course (EOC) examination scores between high school chemistry students taught using POGIL pedagogy and non-POGIL pedagogy in the state of Utah. Piaget's cognitive development theory and Johnstone's…

Natural phenomena and scientific issues are intrinsically interdisciplinary. Students need to study a variety of academic disciplines in the natural sciences to explain a phenomenon or its related problems. Our goal in the current study was to examine the epistemological foundation of students' interdisciplinary understanding of carbon cycling…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

The purpose of this research was to explore the coherence and effectiveness of an assessment approach that combined principles of cognitive-based assessment, performance assessment, and the Next Generation Science Standards. By drawing on research on learning progressions and cognition in geoscience to design, implement, and analyze an Earth…

A dual-enrollment course was designed in which the elementary concepts of organic chemistry were introduced to high school students. Students were assessed at the end of the term using an American Chemical Society (ACS) standardized exam. The same exam was given to corresponding traditional on-campus sections of the same class taught by the same…

Recently Burkholder "et al." argued that class normalized gains over the entire population of courses is approximated by a Cauchy distribution, not by a normal distribution, and therefore should not be used to compare different classes because means and standard deviations cannot be calculated. They argued that multiple linear regression…

The purpose of this mixed-method study is to determine the effect of integrating Engineering design on high school students' scientific reasoning and science achievement. Thirteen eleventh-grade students participated in this eight-week long study. The intervention engaged students in the Engineering design of a functional Dialysis model. Students…

Students' motivational beliefs, such as disciplinary intelligence mindsets, can influence their physics performance and persistence. Intelligence mindset beliefs have long been argued to fall along of continuum between fixed and growth mindsets. Those with fixed physics mindsets believe that ability in physics is innate and unchangable, while…

Georgia adopted science standards encouraging teachers to use inquiry-based instruction in science instruction in 2016 to improve science exam scores. The problem was a lack of improvement in science exam scores in middle school and high school students in a small rural school district in South Georgia since inquiry-based standards have been put…

Local High School, a pseudonym, located in Northwest Mississippi has in place two differing Biology 1 curricula; in one curriculum, the students use interactive notebooks daily and in the other curriculum, they are not used. The purpose of this ex post facto quasi-experimental study was to investigate the impact that an instructional tool, such as…
