This study addressed the following research questions: 1) What is the effect of differentiated gamified instruction on the cognitive engagement of ninth grade students in the unit of plant and animal systems? 2) What is the effect of differentiated gamified instruction on the behavioral engagement of ninth grade biology students in the unit of…

Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

This quantitative study examined the impact of a multi-subject double-dose STEM intervention on the academic achievement of underprepared 9th-grade males. The intervention consisted of heterogeneously grouped core classes of Algebra 1 and biology accompanied by a second multi-subject (Algebra 1 and biology) support class. This nine-week study did…

Science, technology, engineering, and mathematics (STEM) education is an economic opportunity for an urban school district in Tennessee. Lack of interest in STEM courses was throughout schools with underrepresented populations. An urban district in Tennessee with few schools implementing STEM initiated instructional practices to increase…

This three-manuscript dissertation used a rapid PDSA to improve teacher efficacy concerning designing and teaching an unleveled 9th grade science class. Leveling and tracking can lead to inequitable outcomes and experiences for minoritized students. However, designing and implementing effective heterogeneous, unleveled classes that meet the needs…

Ninth-grade students with learning difficulties typically underperform those without learning difficulties, particularly in an integrated geoscience course. Despite the growing demand for STEM careers, science remains challenging to understand and inaccessible to many, especially those with learning difficulties (Vavougios et al., 2016).…

This dissertation focuses on the development and implementation of an action research study that seeks to determine the impact of integrating literacy strategies in the biology classroom on standardized test scores. The teacher-researcher identified the problem of practice in her classroom after four years of observation of ninth-grade biology…

This dissertation is a case study of a school district in the Pacific Northwest that developed three-year high school science curricula using a Physics First course sequence (Physics, Chemistry, Biology), with the crosscutting concept "Patterns" as the central theme of the courses. The purpose of the study was to examine the impact of…

This study examined the effects of the instruction of four youth cultural border crossing behaviors: flexibility, being at ease, playfulness, and citizenship as an intervention aimed at helping students to transition across three borders, student to student, student to science, and student to teacher. The research involved 12 ninth- and 10th-grade…

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of…

This study was conducted in response to the growing concern about the lack of U.S. students majoring in STEM fields and pursuing STEM careers (NSF, 2013). In order for the U.S. to compete in a global economy that is increasingly technologically-based, a skilled STEM workforce is a necessity (National Academies, 2010). Understanding the factors…

The purpose of this within-group experimental study was to find out to what extent ninth-grade students improved their science performance beyond their middle school science performance at one Georgia high school utilizing a freshman academy model. Freshman academies have been recognized as a useful tool for increasing academic performance among…

Co-teaching is a method that is increasing within schools across the US as educators strive to leave no child behind. It is a costly method, having two paid instructors in one classroom, with an average of 24 students shared between them. If it significantly increases the achievement of all students, it is well worth the costs involved. However,…

Analogies are ubiquitous during instruction in science classrooms, yet research about the effectiveness of using analogies has produced mixed results. An aspect seldom studied is a model of instruction when using analogies. The few existing models for instruction with analogies have not often been examined quantitatively. The Teaching With…

Using emergent motivation theory, this study analyzes the relationships between high school students' perceptions of their reading skills, task challenge, and personal control over assigned reading activities and their reading engagement (i.e., interest, enjoyment, and concentration) during science instruction. The study also examines how…
