To enhance critical thinking and problem-solving skills, a project-based learning (PBL) approach for "Instrumental Techniques" courses in undergraduate physical chemistry was specifically developed for a pharmacy bachelor degree program. The starting point of this PBL was an open-ended question that is close to the student scientist's…

Surface structures on the nanometer size scale can impart new and exciting properties to bulk materials. Nanoscopic structures on hydrophobic materials can result in superhydrophobicity and structural coloration. We present an interdisciplinary experiment that introduces undergraduate students to nanotechnology by manipulating the…

Science teachers' practical knowledge of inquiry-based learning influence their beliefs about science teaching and learning. The Indonesian Curriculum released in 2013 has required teachers to teach science via inquiry-based approaches. In fact, some previous studies have found that teachers have difficulties in practically implementing the…

Chemical processes can be fully explained only by employing quantum mechanical models. These models are abstract and require navigation of a variety of cognitively taxing representations. Published research about how students use quantum mechanical models at the upper-division level is sparse. Through a mixed-methods study involving think-aloud…

This study aimed at: 1) Examining the effect of RMS learning model to metacognitive skills. 2) Examining the effect of different academic abilities against metacognitive skills. 3) Examining the effect of interaction between RMS learning model and different academic abilities against metacognitive skills. This study is quasi experiment which…

Global carbon cycling describes the movement of carbon through atmosphere, biosphere, geosphere, and hydrosphere; it lies at the heart of climate change and sustainability. To understand the global carbon cycle, students will require "interdisciplinary knowledge." While standards documents in science education have long promoted…

We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

The use of creativity in science practices is many times lost on secondary students. Creativity is seen as something central to the arts and humanities, but tangential at best in the sciences. However, an examination of many great scientific discoveries and the work of everyday contemporary scientists shows the depth and breadth of the use of…

It is now required for teachers to incorporate computational thinking (CT) into their science classes. Our research modifies the existing structure of a science methods course for preservice teachers to include CT via modeling and simulations. In the first study, preservice teachers were introduced to the basics of coding through an Hour of Code…

Anyone who has spent decades in public education is aware of the pendulum swing of ideas, strategies, and policies that can cause drastic changes. Since the 1980s, inclusion of critical thinking development in classrooms has sharply declined, given accountability mandates and legislation such as No Child Left Behind. A potential reawakening to…

A computational chemistry exercise for the undergraduate physical chemistry laboratory is described. In this exercise, students use the molecular dynamics package Amber to generate trajectories of bulk liquid water for 4 different water models (TIP3P, OPC, SPC/E, and TIP4Pew). Students then process the trajectory to calculate structural (radial…

This study in Zambia examined 66 junior high school pre-service science teachers' familiarity with, conceptual understanding of and levels of interest in learning more about electrochemistry concepts. Data were collected using the Familiarity with Electrochemistry Questionnaire, the Conceptual Understanding of Electrochemistry Test and the…

It is widely agreed upon that the goal of science education is building a scientifically literate society. Although there are a range of definitions for science literacy, most involve an ability to problem solve, make evidence-based decisions, and evaluate information in a manner that is logical. Unfortunately, science literacy appears to be an…

Modeling is considered an important scientific practice, and modeling instruction has the potential to support conceptual change in students in physics. However, when students are not taught how to think about modeling, and how to develop and use models, the learning potential of modeling may be limited. This paper argues that the use and explicit…

We describe a set of conceptual and hands-on activities based around understanding the dynamics of a Slinky that is hung vertically and released from rest. This Slinky drop experiment typically lasts a fraction of a second, but when observed in slow motion, one sees the Slinky compress from the top down while the bottom portion remains at…
