Twenty-first century chemistry education researchers reported challenges in chemistry education pertaining to high school chemistry teaching-learning outcomes. Even though all studies intended to improve chemistry teaching-learning outcomes, unfortunately the impact of chemistry education research found not to be much encouraging. A few of these…

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…

Science performance is highly affected by students' reading comprehension. Recently, there has been a growing attention to the role of linguistic features for science performance, but findings are ambivalent, especially when looking into item word count. The aim of this study was to investigate the interaction of students' reading comprehension…

The impacts of a technology-integrated formative assessment technique on students' conceptual and procedural knowledge in studying chemical equilibrium are studied in this study. To attain the purpose, a quasi-experimental pretest-posttest strategy nested with a qualitative study method was adopted. The study has three groups: two experimental and…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

The purpose of this study was to investigate the effect of 5E learning cycle model oriented instruction (LCMI) on 11th-grade students' conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The study, which lasted for 7 weeks, involved two groups: An experimental group (LCMI) and a control group (the…

A cluster-randomized trial (CRT) relies on random assignment of intact clusters to treatment conditions, such as classrooms or schools (Raudenbush & Bryk, 2002). One specific type of CRT, a multi-site CRT (MSCRT), is commonly employed in educational research and evaluation studies (Spybrook & Raudenbush, 2009; Spybrook, 2014; Bloom,…

The main focus of this study was to investigate if, or to what extent, there is a significant relationship between high school science course sequencing and proficiency on 11th grade Florida Comprehensive Assessment Test (FCAT) Science. The Florida Legislature mandated a specific number of sciences as a requirement for graduation. High schools…

Recent studies on professional development programs indicate these programs, when sustained, have a positive impact on student achievement; however, many of these studies have failed to use longitudinal data. The purpose of this study is to understand how one particular instructional practice (STEM PBL) used consistently influences student…

The Maine Department of Education wanted to use longitudinal data from its data system to better understand whether and how student and school characteristics are associated with student performance on the state-mandated Maine High School Assessment (MHSA). It was particularly interested in understanding the factors associated with changes in test…

This study investigates whether or not (a) 252 Jamaican high school students (168 boys, 84 girls, 171 grade 10 and 81 grade 11 students) had favourable attitudes to biology, (b) their level of biology performance was satisfactory, (c) there were significant differences in their performance based on their gender, grade level, school-type,…

This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean = 28 or 70% and above) or not (less than 70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities…
