The relationship between student activity data and performance in the online classroom is well-documented, yet the parameters of this relationship and their implications for K-12 online schools are not yet well understood. This study examined the role of student chronotype (defined here as the time of day a student is most active in an online…

Collecting data in a mobile augmented reality (AR) settings is challenging, as participants are dispersed in the physical space and move often; therefore, it is imperative that new techniques are investigated to facilitate richer and more ecologically-valid data collection. This study examined three in vivo techniques for collecting authentic data…

Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study. [For "The Data Files: A Series of Articles to Support Mathematics Teachers to Teach Statistics," see EJ1259108.]

This paper is a summary study of team Postgraduate on 11th grade. The objective of this study is to develop a learning model based on problem solving which can construct high-order thinking on the learning mathematics in SMA/MA. The subject of dissemination consists of Students of 11th grade in SMA/MA in 3 kabupaten/kota in North Sumatera, namely:…

This study reports the use of data mining tools in order to examine the influence of the methodology used in chemistry lab classes, on the weight attributed by the students to the lab work on learning and own motivation. The answer frequency analysis was unable to discriminate the opinions expressed by the respondents according to the type of the…

Graphing subjects in chemistry has been used to provide alternatives to verbal and algorithmic descriptions of a subject by handing students another way of improving their manipulation of concepts. Teachers should therefore know the level of students' graphing skills. Studies have identified that students have difficulty making connections with…

The traditional Run the Football Field physics activity--in which students are timed as they move at different speeds on a football field to investigate displacement and velocity--has been updated for the 21st century. Nowadays, GPS-enabled tablets and smartphones replace the stopwatches and yard markers of the past, allowing students to collect…

Teacher practices are essential for supporting learners in scientific inquiry practices of framing research questions, designing and conducting investigations, collecting data, and drawing conclusions. This study examines instructional practices of two Grade 11 Physical Science teachers engaged in teaching practical investigations. Data were…

In 2013-14, the high school graduation rate reached a record high of 82 percent (U.S. Department of Education 2015a). Despite the gains, over half a million students still drop out of high school each year (U.S. Department of Education 2015b). High schools have adopted various strategies designed to keep students who are at risk of not graduating…

This naturalistic study focused on the perceptions of leadership and student performance in science from campus leaders in three purposefully selected secondary campuses of ninth through twelfth grades. Each school had experienced an improvement in student passing rates on the science TAKS test that exceeded the state's percent improvement in…

The Bee Hunt! project and curriculum are designed with cultural and environmental sensitivity in mind. In this project, K-12 students develop their awareness and understanding of science and investigate North American pollinator declines. Bees, butterflies, and other pollinators are integrally connected to the pollination of the world's crops for…

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context-based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the…

This study investigated the conceptual pathways of 19 Grade 11 introductory chemistry students (age 16-17) as they participated in a multirepresentational instruction on the particulate nature of matter (PNM). This study was grounded in contemporary conceptual change theory, in particular, research on students' conceptual pathways that focuses on…

There is a growing emphasis on academic performance and educational outcomes for students with disabilities. This focus is demonstrated, in part, by the federal requirement to collect post-school outcome data from these former students (i.e., Indicator 14). The purpose of this paper is to introduce two states' approaches to collecting post-school…

This report examines the results of the field test for the base year of the High School Longitudinal Study of 2009 (HSLS:09). The general purposes of the field test were, in anticipation of the base-year full-scale effort, to test instruments, forms, and procedures; to experiment with different approaches to questionnaire content and survey…
