Learning a second language is a complex task. Adopting the innovative use of a multimodal literacies approach provides young second language (L2) learners with expanded opportunities to immerse themselves in the target language. This study explored how participants utilized their multimodal literacies along with the level of investment…

Errors in mathematics are common hurdles for teachers and students; therefore, it is important to learn what errors students make and how students treat them. This study initially identified the types of errors students made while working with algebraic expressions and documented and analyzed the process of students completing an error analysis…

The Common Core State Standards for Mathematics emphasize the importance of developing students' conceptual understanding, mathematical reasoning, and problem solving skills. This is a shift from the traditional approach to teaching mathematics and many teachers rely on curriculum resources to help them meet these new standards and expectations.…

The No Child Left Behind Act (NCLB, 2006) set a precedent that established even higher expectations for all students, including those with disabilities. More recently, the National Governors Association Center for Best Practices and the Council of Chief State School Officers developed a common set of state standards for proficiency in English…

Morphological skills have been associated with performance on multiple literacy outcomes. While growth in derived word knowledge has been documented during mid-elementary grades, little research has studied the development of knowledge of specific morphemes, separate from whole-word knowledge. This study examined the development of knowledge of a…

The aims of this study were to investigate how upper-elementary-grade students compare the volume of rectangular prisms of equal volume (specifically, students' noticing and reasoning for invariance of volume and coordination of the three linear dimensions of rectangular prisms) and how students' levels of sophistication in volume measurement…

Professional development (PD) is key to improving mathematics teaching and learning in the middle grades. Many PD projects and initiatives have been undertaken across the United States. Yet, we know very little about what teachers learn in and through such PD, nor about what those who conduct the PD might be learning as well. This knowledge gap…

This study reports how 24 grade 4-6 students in one elementary and middle school interpreted formal and informal representations of variables. While interpretations for variables represented as letters (e.g., x and y) have been well established for students in algebra classes and beyond, little research into elementary school students'…

Two choice-making interventions (task sequence and where) were implemented by a classroom teacher to determine the effects on the percentage of task completion, accuracy, and classroom disruption for ten sixth through eighth grade students with E/BD in a residential math classroom using a reversal design. An FBA was conducted to determine the…

The purpose of this study was to determine the relationship between Collective Teacher Efficacy and minority student achievement gap over and above that explained by socioeconomics, school size, and prior achievement gaps for Black and Hispanic students with White students. Forty-seven Virginia middle schools were selected to participate in the…

Size and scale are crosscutting ideas integral to scientific understanding. However, research shows that students have little understanding of the size of objects, particularly objects too small to see with the unaided eye. Using a cross-sectional study with 101 middle-school through undergraduate students, a teaching experiment with 24 middle…
