Instruction plays a critical role in student success. However, most studies of teachers' effects on student learning focus on face-to-face settings. Some aspects of online courses, such as the choice of synchronous or asynchronous instruction and the course structure, might reduce teachers' influence on their students. For example, online courses…

Despite proliferative use of anatomical virtual models, there are few studies exploring whether stereoscopic models help medical students retain information regarding three-dimensional (3D) relationships of structures. This pilot study examined first-year medical students' exposure to a virtual 3D stereoscopic pelvis model and their corresponding…

This study was designed to determine the effect of computer simulation instructional strategy on primary school pupils' achievement in basic science in Akure township in Ondo state, Nigeria. Constructivist theory was used as the framework, while the study adopted pretest-posttest control group quasi-experimental design. Four primary schools were…

Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main challenge of this teaching strategy is to stimulate students to watch these videos attentively before going to class. This paper describes the use of questions that pop-up within relatively long…

In this research an instrument was developed to measure students' anxiety about the jargon of physics. Levels of anxiety were then compared with student content performance and general classroom anxiety. Anxiety levels were also compared based on students' language of origin (native vs. nonnative English speaking students). Statistical analyses…

In previous published articles, formulae-based mnemonics by counting the total number of s bonds with a lone pair of electrons (LP), a localized negative charge (LNC), or a localized lone pair of electrons (LLP) and subtracting one (01) from this total value (TSLP, TSLNC, or TSLLP) to predict the power of the hybridization state of simple…

This paper is designed to synopsize the efforts of a team of general chemistry teachers to enact assessments during the abrupt transition to online-only instruction and reflect on what was done successfully and what could be improved. The focus is on the extent remote, online assessments accurately measured student knowledge described within the…

With limited time available in the classroom, e-learning tools can supplement in-class learning by providing opportunities for students to study and learn outside of class. Such tools can be especially helpful for students who lack adequate prior preparation. However, one critical issue is ensuring that students, especially those in need of…

Science students are increasingly challenged to use technical language related to the topics that they are studying, and therefore, science teachers benefit from knowing which tools are effective to support students in learning to use new terms. This study examined the impact of using one such tool--sentences frames--to teach science vocabulary,…

The identification of students' mental models is crucial in understanding their knowledge of scientific concepts. This research aimed to develop a Mental Models Representation Instrument on Newton's Laws (MeMoRI-NL). The ADDIE (Analyzing, Designing, Developing, Implementing and Evaluating) model was used as a research method. The sample consisted…

This study investigated the predictive effects of science self-efficacy, value in learning science, science attitudes, gender, and race on science achievement, among United States middle school students utilising Trends in International Math and Science Study 2011 data. A series of preliminary analyses using several descriptive statistics,…

In 2017 the University of Utah experienced a tragedy which catalyzed already active changes in the department. In the aftermath, admissions to the graduate program was paused while new policies were developed and implemented. This article outlines this change process through the perspectives and accounts of those involved. Through in-depth…

Practical classes are an important and essential part of undergraduate programs in Chemical Engineering, as each experiment provides an opportunity to reinforce the theory of discrete unit operations that are taught elsewhere in the course. While an expensive pedagogical method, when practical sessions are delivered well, they can be one of the…

The present study intends to explore the level of practical examination anxiety among secondary and higher secondary school students and its causes and remedies. A self-developed Perceived Science Practical Anxiety Scale (PSPAS) was used to collect quantitative data from 900 science students of two districts of central Punjab: Sargodha and…

A laboratory experiment was designed for upper-level undergraduate students in a bioanalytical course to demonstrate the concept of isoelectric point (pI) and the theoretical and practical applications of isoelectric focusing (IEF). This simple and inexpensive IEF procedure requires the same minigel SDS-PAGE equipment that is already available in…
