In this study, we investigated the relationships between three pivotal factors that influence student performance, including opportunity-to-learn (OTL) factors, which included proximal indicators that represent science-specific learning opportunities, student motivation (propensity factor), and crucial student and teacher antecedent factors by…

Self-efficacy and achievement goals represent two extensively researched motivational factors in education and have been related to numerous academic outcomes. However, little is known about how they relate to different types of problem-solving. Furthermore, while prior work has found these motivational factors are related, less work has examined…

The paper reports about an empirical study investigating the relationship between scientific epistemological beliefs, intellectual risk-taking in science learning and science achievement of middle school students via path analysis. The sample was composed of 2119 middle school students enrolled in public schools. Nearly half of the students…

Reading comprehension is an essential skill for learning in general and in science classes. Problems with reading comprehension might hinder students' participation in learning science. Text in science includes specific language features that distinguishes it from narrative text, so should reading instruction be part of teaching science? The…

The purpose of this study was to investigate the student and teacher-level predictors of Turkish middle school students' engagement in science classes. Students' engagement was examined in terms of agentic, behavioral, cognitive, and emotional engagement. The participants of the study were 134 Turkish science teachers and their 3394 grade 7…

A hotly debated topic is the effectiveness of inquiry-based instructional practice in science classrooms on student achievement and motivation. Numerous studies based on multinational large-scale education data show such student-centered instructional practice positively led to students' motivational beliefs but was negatively associated with…

Academic language is a kind of social language for the purpose of schooling. It is central to disciplinary learning, thinking, and communication. This study examined adolescents' use of academic language in informational writing, a genre highly valued in school, workplace, and society. Ninety-three seventh and ninth grade students from a U.S.…

Researchers have highlighted how tracking learners' eye-gaze can reveal their reading behaviors and strategies, and this provides a framework for developing personalized feedback to improve learning and problem solving skills. In this paper, we describe analyses of eye-gaze data collected from 16 middle school students who worked with Betty's…

Mid-adolescence is a period of considerable potential growth in the language for academic writing. Yet, to date, few writing studies explore language development during this period and even fewer focus on longitudinal or diverse samples. In this study, we examined the development of language skills for academic writing in a socio-economically…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

The purpose of this quantitative study was to compare and evaluate two types of vocabulary interventions using grade 9 physics vocabulary terms using two lists of 10 words. A quasi-experimental crossover research design was used to compare the two interventions, presented during two separate sessions, 1) active, multimedia that includes the…

This study investigated middle school students' engagement in science in relation to students' perceptions of the classroom learning environment (teacher support, student cohesiveness, and equity) and motivation (self-efficacy beliefs and achievement goals). The participants were 315 Turkish sixth and seventh grade students. Four hierarchical…

Anson County School District wished to determine the relationship between Fast ForWord Scientific Learning data and North Carolina End of Grade reading scores at Anson Middle School in Anson County, North Carolina. The specific research questions that guided this study include: 1. How does the literacy intervention, Fast ForWord, affect EOG growth…

In an experimental study (N = 209), the authors compared the effects of exposure to typical middle-school written science content when presented in the context of the scientific discovery narrative and when presented in a more traditional nonnarrative format on 7th and 8th grade students in the United States. The development of texts was…

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child-…
