Curricular analysis indicates that the U.S. students are introduced to multiplication in additive terms (as the replication of equal groups and repeated addition). But the virtue of this introduction for supporting students' understanding of the full range of multiplicative relationships is unclear. This paper reports an analysis of all grade 4…

In this study, I investigated Grade 4 and 5 students' emotions while they engaged in the exploration of unsolved mathematics problems, including parts of the Graceful Tree Conjecture. Ten students from an after-school program in the Midwest participated in seven task-based interviews. The students exhibited a variety of emotions throughout the…

The aim of this study is to develop a valid and reliable Likert-type attitude scale for toward story writing for third- and fourth-grade primary school students. 354 children from three different schools in the Eregli district of Zonguldak province, Turkey constituted the sample of this research. Exploratory factor analysis (EFA) and confirmatory…

This paper addresses the initial components of an activity in which 4th-grade students engaged in meta-questioning as they created and refined survey questions with the aim of comparing life across two Australian cities. We propose the term, "meta-questioning", as a core, underrepresented feature of statistical investigations in the…

This study investigates consistent and inconsistent respondents to mixed-worded questionnaire scales in large-scale assessments. Mixed-worded scales contain both positively and negatively worded items and are universally applied in different survey and content areas. Due to the changing wording, these scales require a more careful reading and…

This research explored dream science classrooms of primary school third and fourth-grade students. Research is designed as a case study. The students were first asked to illustrate their dream science classroom and produce a short description of their drawings. Second, they were asked to write their expectations of their teachers, their…

We address the question: How can a student's conceptual transition, from attending only to singleton units (1s) given in multiplicative situations to distinguishing composite units made of such 1s, be explained? We analyze a case study of one fourth grader (Adam, a pseudonym) during the course of a video recorded cognitive interview. Adam's case…

Automatic speech recognition (ASR) can be used to score oral reading fuency (ORF) assessments to ameliorate current inadequacies (e.g., administration errors, high opportunity cost), and represents an important part of a larger solution to improve traditional ORF. But more research is needed on how ASR performs for diverse student groups. The…

Studies based on response processes of individuals can provide information that supports the assessment and increases the validity of the items in the scale or tests. The purpose of this study is to present the extent to which the student response processes are effective in identifying and developing the characteristics of the items in an…

This paper proposes structural modification of the Clarke and Hollingsworth (2002) Interconnected Model of Teacher Professional Growth (IMTPG) based on results from doctoral research that studied the changes in mathematical knowledge and beliefs of two Year 5/6 teachers as they implemented a four-week, innovative curriculum unit. These inclusions…

This paper contributes to the Symposium: "Research Methods Involving Children's Drawings in Mathematical Contexts" by exploring the use of digital pens as a data gathering tool. The availability of digital recording devices has been a boon to researchers wanting to capture the real-time dynamics of a research situation. When capturing a…

This study is designed to assess the effects of states' adoption of college- and career-ready (CCR) standards on student achievement. Relying on state-level NAEP data from 1990 to 2015, we use comparative interrupted time series analyses to assess whether the adoption of CCR standards led to a larger improvement in student achievement in states…

In this study, we use large-scale, longitudinal data to model the growth in student reading across 3rd, 4th, and 5th grade in three states using multi-level models for change (Singer & Willett, 2003) to fit individual growth models for students nested in schools and districts. Students who were identified as gifted had 3rd grade reading scores…

The Science Notebook in a Universal Design for Learning Environment (SNUDLE) is a digital notebook that uses the Universal Design for Learning framework to support active science learning among elementary school students, particularly those who struggle with reading and writing or are unmotivated to learn science. Preliminary findings from the…

The paper presents results from the evaluation of the Teach for Bulgaria (TFB) program, which is part of the Teach for All global network. TFB activities have relevance for a variety of fast-track pathways to the teaching profession. The evaluation is based on a quasi-experimental assessment of teacher performance through student value-added…
