Student's ability to use and manipulate scientific concepts has been widely explored; however there is still a need to define the characteristics and nature of science ability. Also, the tests and performance scales that require minimal conceptual knowledge to measure this ability are relatively less common. The aim of this study was to develop an…

Students' self-efficacy expectations (SEE) in mathematics are associated with their engagement and learning experiences. Going beyond previous operationalisations of SEE we propose a new instrument that takes into account not only "facet-specificity" (expectations related to particular competences or skills) and "strength"…

The intention of the present study is to know how students' performance on number sense based on the components of number sense and also the sub-components in it. The participants of the study are 80 six graders (12-13 year-old) from three different schools that represent the city, rural, and small town areas. The data were collected using the…

Developing instructional capacity in schools is a central challenge of the Common Core movement. Most conceptualizations of capacity building focus on infusing externally generated professional development into schools. In this article, we explore the professional resources that reside inside schools that might be utilized to develop instructional…

Pair programming is a strategy that grew out of industry and has shown promise for performance and retention in computer programming courses at universities and in industry. In this study, we examine whether pair programming is effective in K-12, what it is effective for, and how partners influence each other. We collected the data from 320 middle…

We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

While today's curriculum is largely driven by standards, many teachers find the lack of specificity in the standards to be confounding and even intimidating. Now this practical book provides middle and high school teachers with explicit guidance on designing specific objectives and developing appropriate formative and summative assessments to…

This paper reports a study on elementary students' ideas regarding changes in mass associated with melting. An open-ended probe was designed and distributed to fifth-grade students (n = 230). In addition, 50 students were asked their reasons behind predictions on mass change. The written responses indicate that, despite conventional teaching,…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

For four years middle-level students and science teachers have participated in a two-week summer workshop outreach project collaboratively designed and implemented by School of Medicine and Department of Education faculty. The project's goals included improving the attitude of student participants toward the study of science; increasing…
