A traditional classroom usually focuses on concepts from a specific discipline. However, solving complex real-world problems requires integration and application of knowledge from various fields. Here, we describe a 4-hr undergraduate-level laboratory exercise that utilizes concepts of extraction and biological property, bridging between chemistry…

Models that are used to predict and explain phenomena related to molecular vibration and rotation are ubiquitous in physical chemistry, and are of importance in many related fields. Yet, little work has been done to characterize student use and application of these models. We describe the results of a multi-year, multi-institutional qualitative…

Although hands-on experience in hematology practical work has been an integral part of physiology education, the students' perception on the importance of the same has remained largely unexplored. The objective of this study was to explore students' perception on the importance of "doing" hematology experiments. The first-year medical…

This study aims to investigate the effects of Science Technology Education Math (STEM) practices on academic achievement and motivations of students in the 5th grade of middle school in "Exploring and Knowing the World of Living Creatures" section in Science lecture. The study was designed in a semi-experimental pattern with pre-test…

In this paper, we present a novel dynamical approach to teach circular motion. According to the principle of inertia, objects without external influences move in a uniform and straight way. With a kick, one can turn the motion towards one side. By successively continuing these turns, a complete circle can be reached. With the help of standard…

At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school-aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest…

This applied dissertation was designed to determine if there is a difference between students' gender, ethnicity, and age and their performance in General Chemistry I at a Christian University in Florida. Many scientific studies reveal the existence of a gender performance gap in chemistry: women mostly underperform men. Certain factors reported…

The purpose of this descriptive case study was to describe the successful instructional strategies that influence student engagement in an urban elementary school in Virginia. This study was designed to focus on the instructional strategies' teachers use to teach science and how those instructional strategies influence student engagement in third,…

The American Museum of Natural History (AMNH) in New York City implemented a science-based curriculum pairing augmented reality (AR) with a student-designed escape room experience to support astronomy learning. AR has the potential to simplify complex systems into digestible concepts. Designing an escape room experience provided students with an…

A major aim of science education reform documents (Achieve, 2013) is for K-12 students to engage in scientific practices to facilitate a better understanding of the processes and the aspects of doing science (Bybee, 2014). In this design case we present the design of a teaching unit on a socio-scientific issue (SSI) that can potentially engage…

A well-known physics demonstration is to pull a tablecloth rapidly from under some crockery without disturbing the crockery. An interesting question is whether the same result can be expected if the crockery is replaced by a ball, given that the ball might roll backwards on the tablecloth. Theoretical and experimental results are presented showing…

Some new experiments using an improved version of the "tornado tube" are described here. The improved tornado tube consists of two plastic transparent bottles whose openings are connected with a ball valve, available at most hardware stores. After being filled with fluid and inverting, this tube allows demonstration of the generation,…

Questions serve as an element that can be used to access and stimulate students' thinking ability. This research aimed at analyzing the students' ability to pose Higher-Order Thinking Skills (HOTS) questions during the learning process. This research was a survey research using a descriptive quantitative approach. The samples used in the research…

The purpose of this research is to know how the attitude of junior high school students to science mathematics with three indicators adopted from TOSRA are: 1) pleasure in learning science, 2) interest to increase study time of science, and 3) interest in a career in the science field. This research uses survey type research with design research…

We look at the problem of the minimum speed of projectiles in a constant gravitational field. In the absence of resistance, the problem may be studied in the frame of a high school curriculum. One needs only Newton's laws and a minimum amount of analytic geometry to compute the orbit, which turns out to be parabolic. Furthermore, in case the…
