This article presents findings of a study conducted to determine the impact of academic support provided through videoconferencing on the academic outcomes of Science, Technology, Engineering, and Mathematics students enrolled in high-risk science courses in higher education. A quasi-experimental nonequivalent posttest only design was employed to…

A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to…

We analyzed effects of peer teaching on non-science major undergraduates' knowledge, perceptions, and opinions about genetically modified (GM) crops and their use in agriculture. Undergraduates enrolled in an introductory nonmajors biology course participated in a service-learning program (SLP) in which they acted as cross-age peer teachers to…

This paper presents results from a randomized experimental design replicated over four semesters that compared students' performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods…

Situated within the CID (Communication in the Disciplines) theoretical framework that promotes the focus of communication instruction on the oral genre standards of effectiveness, and employing a transdisciplinary approach, the current study explores science students' attitudes and motivation concerning an oral skills development (OSD)…

The purpose of this research was to know the effect of blended learning strategy on learning achievement and science process skills of students in plant tissue culture course in the Universitas Negeri Medan. The research method was quasi experiment. The population of this study was all semester VIII students of biology education program. The study…

The flipped classroom pedagogy was implemented in two core undergraduate science courses; Animal and Plant Biochemistry II (APB) and Microbiology and Invertebrate Biology II (MIB) to encourage students to prepare for laboratory classes. Students often attend class without little understanding or appreciation of what they are going to learn in the…

Currently, the number of smartphones with an embedded gyroscope sensor has been increasing due games whose performance relies on 3D augmented reality. In general, teaching papers on the gyroscope sensor address very simple spatial configuration, where the fixed rotation axis coincides to the z-axis of the smartphone. This work presents five…

Graduates' retrospective program evaluations can provide relevant and reliable feedback on an institutions' performance in delivering quality instruction and services to its students. This descriptive survey research ascertains graduates' evaluations of science education program areas, including curriculum adequacy and relevance. Study…

A Sonogashira experiment was transformed into a problem-based learning platform for third-year undergraduate students. Given a target that could be synthesized in a single step, students worked in groups to investigate which method was the best for large-scale production. Through this practical scenario, students learn to conduct a literature…

The role of practical work in the training of student teachers is central to the development of their future pedagogy and practice. However, not all laboratory based activities give sufficient challenge in the development of both cognitive and practical skills. The activity proposed in this paper helps reinforce an understanding of reaction…

In biology education research, it has been common to model cognition in terms of relatively stable knowledge structures (e.g., mental models, alternative frameworks, deeply held misconceptions). For example, John D. Coley and Kimberley D. Tanner recently proposed that many student difficulties in biology stem from underlying cognitive frameworks…

Fundamental quantum chemistry concepts--quantization of energy, electronic structure, and light-matter interaction--are essential for understanding chemistry and spectroscopy, an important tool for studying molecules. However, very few studies have investigated how students learn and understand these concepts or how their learning can be…

It is well known that many students have tremendous difficulties with applying Gauss's law for purposes of solving quantitative as well as qualitative problems. In this study, it was investigated how understanding of Gauss's law can be facilitated by analyzing the superposition of electric field vectors for increasingly complex geometric…

Analyzing and interpreting data is an important science practice that contributes toward the construction of models from data; yet, there is evidence that students may struggle with making meaning of data. The study reported here focused on characterizing students' approaches to analyzing rate and concentration data in the context of method of…
