This study aims to investigate the effect of Resource Based Learning Design Thinking (RBLDT) model to improve student's creative thinking skills, concept gaining, and digital literacy. It is a quasi-experimental study using pre-test and post-test nonequivalent control group design. Furthermore, it was conducted at several senior high schools in…

We investigate upper-division student difficulties with direct integration in multiple contexts involving the calculation of a potential from a continuous distribution (e.g., mass, charge, or current). Integration is a tool that has been historically studied at several different points in the curriculum including introductory and upper-division…

This study designs and implements interdisciplinary STEM instruction by adopting modelling-based physics programming, and explores its effectiveness on learning. A quasi-experimental study was conducted. The experimental group wrote programs to solve physics problems by following the modelling process, while the control group solved general…

Problem Roulette (PR), an online study service at the University of Michigan, offers points-free formative practice to students preparing for examinations in introductory science, technology, engineering, and mathematics courses. Using four years of PR data involving millions of problem attempts by thousands of students, we quantify the benefits…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

As a foundational evolutionary concept, the Hardy-Weinberg principle should be taught enthusiastically in introductory biology courses. In a companion Perspectives paper, I made the case that students are often given limited or incorrect information on the HW principle due to a lack of mastery or confidence on the part of their teachers. The…

Le Châtelier's principle is used as a basis to derive an expression to calculate solution pH during titrations that involve only strong acids and strong bases. Central to this model are the reaction quotient and a re-equilibration term that represents the extent of neutralization during a titration. Unlike the method traditionally taught to…

An important but challenging problem-solving technique in introductory mechanics is that of using "tilted axes." For inclined plane and centripetal motion problems, using axes that are aligned relative to the ramp direction or the radial direction (rather than the horizontal and vertical) yields equations that are conceptually more…

Chemical engineering problems often involve the solution of systems of nonlinear algebraic equations (NLE). There are several software packages that can be used for solving NLE systems, but they may occasionally fail, especially in cases where the mathematical model contains discontinuities and/or regions where some of the functions are undefined.…

The need to develop clean-energy storage systems, harvesting technologies, and new functional materials are but a few of the many contemporary challenges in the domain of science today. To address these challenges, problem solving has become a key skill of the 21st century. It is generally documented, however, that experts and students differ in…

The case study described in this article focused on a topic of real national concern, landslides, which can trigger sudden and tragic environmental problems and bring considerable loss of life. Landslides occur in many parts of Thailand, for example on mountain slopes, areas eroded by water or areas with rock degradation (Department of Mineral…

Novel assessment tools are more often used in class especially after the Bologna Process (Pereira, D.; Flores, M. A.; Niklasson, I. Assess. "Eval. Higher Educ." 2016, 41, (7), 1008-1032, DOI: 10.1080/02602938.2015.1055233) in Europe. "Kahoot" has emerged as an attractive and interactive gaming platform, and considerable…

Mathematics is of major importance in science subjects. Unfortunately, students struggle with applying mathematics in science subjects, especially physics. In this qualitative study we demonstrate that transfer of algebraic skills from mathematics in physics class can be improved by using pre-knowledge effectively. We designed shift-problems…

This research study was conducted to examine the effectiveness of activity-based science teaching practices on the acquisition of problem-solving skills for 5-6 year old preschool children. A total of 32 children were included in this research study. The Personal Information Form and 4-7 Age Problem Solving Ability Scale were used as the data…

The flipped classroom is a relatively new active learning pedagogical intervention, gaining popularity as a blended learning methodology. The flipped classroom comprises two distinct parts, directed learning carried out at the student's own pace away from the classroom and an interactive, class-based activity encouraging problem-solving and…
