Dropout and low academic performance at university level constitute a big current challenge. In this work, materials comprising different interactive tools were developed following instructional design, rooted in the cognitive load theory. They were applied in a first-year lecture chemistry course to tackle low academic performance and high…

Scientific literacy is an important skill for students' success, given the characteristics of today's society. However, not all students have a natural predisposition toward science, chemistry in particular. Considering the relevance of transdisciplinary learning, schools should foster the scientific abilities for which students may have less…

To help educators deliver their physiology laboratory courses remotely, we developed an inexpensive, customizable hardware kit along with freely available teaching resources. We based the course design on four principles that should allow students to conduct insightful experiments on different physiological systems. First, the experimental setup…

Long before the "Next Generation Science Standards" ("NGSS") were formalized, sensors and other probeware engaged students in science and engineering practices (Metcalf and Tinker 2004). A new generation of probeware based on modern Internet of Things (IoT) technologies is beginning to expand the ways that students can…

The Integrated Concentration in Science (iCons) 4-year program at the University of Massachusetts Amherst was designed to promote interdisciplinary STEM collaboration in the solution of real-world problems and encourage student independence and interdependence through a student-centered teaching approach that structures all projects as group…

The current work explores the secondary school teachers' and students' perception on web-based discussions in teaching and learning and its potentiality to enhance students' performance in organic chemistry. A mixed approaches typically interviews and achievement tests were applied for collecting qualitative and quantitative data respectively for…

We introduce two new software tools, Bongojontro and Bongojontro Baksobandi, aimed at reducing the barriers to programming for native speakers of Bengali, the fifth most spoken language in the world. The highlights of these software include programming in the native language of Bengali, simpler construction of programs which is friendly for…

Scientists rely heavily on tree-ring records to better understand climate variability of the past millennium. Tree rings can also be utilized to give students a window into paleoclimate research, the methods scientists use, and the importance of scientific findings. Here, we present five online labs that introduce undergraduate students to the…

Innovative didactive strategies such as online learning and flipped classroom can improve student performance while maximizing university resources and personnel. Assessing how students perceive courses designed using these strategies, as well as perform within them, is becoming increasingly important. An introductory soil science course at a…

The paper reports about a study that examines changes in teachers' incorporation of epistemic practices in their design of engineering lessons and compares them to their views about the nature of engineering knowledge across 100 hours of professional development. Nineteen K-8 teachers in the USA, who were new to teaching engineering as part of a…

Inspired by the approach first employed by C.S. Holling in his classic "disc experiment," this article provides a sequence of learning activities that increase students' understanding of the mechanisms behind saturating effects in predator-prey scenarios. The proposed lesson is recommended for inclusion in courses that address…

The present work describes a simple hands-on experiment kit for colorimetric quantification of ferric (III) ion (Fe[superscript 3+]) in an aqueous medium using anthocyanin extracted from "Ruellia tuberosa" L. as a green indicator. The extraction of a high amount of anthocyanin was easily accomplished by using only hot water instead of an…

The increased demand for bilingual education has resulted in a growing need for professionally and linguistically qualified teachers whose shortage is evident in most Slovak schools. As science subjects form a major part of bilingual school curricula, the aim of our research is to determine the current situation from the combined opinions of…

The objective of this article is to identify and discuss the views of teachers of physics-chemistry (Ph-Ch) and Life and Earth Sciences (LES) on the use and effectiveness of interactive simulations PhET (Physics Education Technology) in student teaching and learning. A survey research method was used in this study. 114 Moroccan science teachers…

The present study aimed to determine the effects of arduino-assisted robotics coding applications integrated into the 5E learning model used in science teaching on students' scientific creativity, robotics attitude and motivation toward science. For this aim, the study was planned according to the convergent parallel mixed research method and was…
