A hydroponics experiment growing microgreens was piloted by seniors where trials were conducted over 9-day growth periods and designed to test 12 different growth conditions in triplicate, including varying nutrient supply, nutrient flow rate, and seed density. Plant growth was assessed through changes in daily mass, height, and final dry weight.…

Twenty-first-century skills are increasingly recognized as critical skills that today's students must develop to adapt to increasingly rapid world changes. This research aims to test the effectiveness of the STEM-EDELCY learning model to improve students' 21st-century skills. This research involved 285 junior high school students (aged 12-13) from…

Reform efforts in K-12 science education have been gaining pace ever since the introduction of the "Next Generation Science Standards" (NGSS). The new vision calls for reconsidering teacher preparation programs to prepare future teachers who are confident and competent in delivering NGSS-based instruction. This study investigated the…

The problem addressed in this study was high school science teachers' lack of understanding of science, technology, engineering, and mathematics (STEM) and clarity for the integration of Next Generation Science Standards (NGSS) approaches to align standards in STEM with high school science education. The purpose of this qualitative case study was…

The current US science education reforms call for integrating engineering design in science instruction requires teachers to develop and teach engineering design-integrated science (EDIS) lessons. However, very few teachers have received training in engineering and how to integrate engineering design into science lessons. In response to this…

This research investigates students' argumentation quality in engineering design thinking. We implemented Learning by Evaluating (LbE) using Adaptive Comparative Judgment (ACJ), where students assess pairs of items to determine the superior one. In ACJ, students provided rationales for their critiques, explaining their selections. Fifteen students…

A problem-based learning (PBL) methodology was implemented to a project, whose main objectives were to discuss and apply the Twelve Principles of Green Chemistry to the study of poly(vinyl alcohol)'s cross-linking reaction with dicarboxylic acids. The five participating students were oriented to be responsible for their own learning and the…

In their collegiate studies, students are given a wide range of concepts, theories, and equations to assist them in their future endeavors. However, students have not been sufficiently exposed to practical critical thinking methodologies that will benefit them as they encounter open-ended problems. A course developed at the University of Michigan…

In this work, a specific implementation of a so-called experimental or open-ended laboratory is proposed and evaluated. Keeping in mind the scheduling limitations imposed by the context, first-year engineering physics laboratory practices have been revised in order to facilitate acquisition of the skills that are required in the experimental work.…

Do young children naturally develop the foundations of science, technology, engineering, and math (STEM)? And if so, should we build on these foundations by using STEM curricula in preschools? In this article, Douglas Clements and Julie Sarama argue that the answer to both these questions is yes. First, the authors show that young children possess…

The Next Generation Science Standards emphasize the need to promote equitable opportunities for all students to engage in science and engineering. This article offers eight tips that educators can use to support students of all abilities, including those with special learning needs, to engage in engineering challenges at the elementary level.

The aim of the International Society for Technology, Education, and Science (iHSES) conference is to offer opportunities to share ideas, discuss theoretical and practical issues, and connect with the leaders in the fields of "humanities," "education" and "social sciences." It is organized for: (1) faculty members in…

The new reorganization of university education has involved relevant changes in teaching and learning methodologies in order to help students to learn more effectively and to develop important skills and competences demanded by the professional world. In this sense the new configuration of the degree in Chemical Engineering required the…

An academic and professional development course has been introduced to help first-year chemical engineering students to deal proactively with the transition from secondary school to university and to develop professional skills. The course uses the Myers-Briggs Type Indicator (MBTI) as a personality model to facilitate skills development and many…

"Engineering Challenge for the 21st Century," a weeklong teacher workshop sponsored by the National Science Foundation, uses project-based learning (PBL) to help students and teachers build science, technology, engineering, and math (STEM) skills. The workshop, hosted by the U.S. Coast Guard Academy in New London, Connecticut, features the Coast…
