This study investigated how students' and teachers' pedagogical roles in mobile learning moderated the relationship between high school students' perceived usefulness of mobile technology and the actual use frequency, as well as how students' perceived usefulness impacted their physics learning achievement. We examined 803 high school freshmen who…

In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

This research study is an investigation of student-laboratory (i.e., lab) learning based on students' perceptions of experiences using questionnaire data and evidence of their science-laboratory performance based on paper-and-pencil assessments using Maryland-mandated criteria, Montgomery County Public Schools (MCPS) criteria, and published…

We investigated the impact of an augmented reality (AR) versus interactive simulation (IS) activity incorporated in a computer learning environment to facilitate students' learning of a socio-scientific issue (SSI) on nuclear power plants and radiation pollution. We employed a quasi-experimental research design. Two classes (a total of 45…

The present study examines whether the seductive-details effect is moderated by spatial ability and prior knowledge, which are two of the most relevant learner characteristics in multimedia learning. It is assumed that the seductive-details effect with an increase in extraneous cognitive load and a decrease in perceptual processing and learning…

The goal of this study was to determine if laptop use in lecture negatively impacts learning outcomes of surrounding students taking notes on paper. Two sections of a large introductory biology course (greater than 400 students/section) were zoned into a laptop-permitted and a laptop-free area. Two sections in which laptop users could sit anywhere…

The purpose of this quantitative causal-comparative study was to investigate the relationship between the instructional effects of the interactive whiteboard and students' proficiency levels in eighth-grade science as evidenced by the state FCAT scores. A total of 46 eighth-grade science teachers in a South Florida public school district completed…

During the beginning years of teaching, science teachers develop the knowledge and skills needed to design and implement science laboratories. In this regard, this quantitative study focused on the reported laboratory practices of 61 beginning secondary science teachers who participated in four different induction programs. The results…

This study examines middle school students' learning and motivation as they engaged in a new media enriched problem-based learning (PBL) environment for middle school science. Using a mixed-method design with both quantitative and qualitative data, we investigated the effect of a new media environment on sixth graders' science learning, their…

The purposes of this study were to investigate students' conceptual learning outcomes and the effect of motivation on students' conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were…

Teaching presence is one of three components of the Community of Inquiry Model proposed by Garrison, Anderson, and Archer (2000). This study examined teaching presence, as measured by the instructional design and organization, and directed facilitation (Shea, Li, Swan, and Pickett, 2005), in a large undergraduate science course, contrasting two…

Various modern electronic structure methods are now days used to teach computational chemistry to undergraduate students. Such quantum calculations can now be easily used even for large size molecules.

This study examines the practical work of a pair of students and an instructor using probeware in a mechanics lab. The aim of the study is to describe and discuss a type of interactional sequence that we refer to as "dark matter", the ordinary backdrop to the extraordinary sequences that are easily recognizable as clear-cut instances of learning.…

This paper reports the findings of a study of student attitudes and student improvement in conceptual understanding using conceptests with an electronic response system in lecture courses. Students and instructors valued the feedback and interaction that the response system afforded. For a majority of the chemistry topics studied, student…
