This article is the first in a new series of hands-on activities designed especially for early childhood students to encourage their natural curiosity and promote development of scientific thinking. The activity presented was created to help children learn how to make scientific observations using their senses. Children develop science inquiry…

The purpose of this research was to design and develop hands-on practical physics activity for the determination of relationship between the fundamental frequency and wavelength of standing waves using open or closed resonance tubes. In this study, an innovative use of smartphone device for the hands-on practical activity was developed with the…

The purpose of this study was to examine the effects of using 'hands-on' models (HOMs) to teach the subject of seasons--a topic about which students often have misconceptions--on students' expressed models. To this end, three different HOMs were developed. The study sample consisted of 80 seventh graders (ages 12-13). The study had a…

Youth are introduced to STEM topics through informal settings like science camps, aquaria, and zoos. In these interactive and sensory-rich environments, a well-designed programme can help participants to acquire knowledge and cultivate interest through experiential learning. Given the importance of informal activities in environmental education,…

Large gender gaps in performance on questions involving projectile motion have been observed at high school and university level, even amongst high-achieving students. This gap is particularly problematic because projectile motion is typically one of the first topics formally taught in physics, and this may give girls an inappropriately negative…

This article is a qualitative study that explored bilingual/ESL science teachers' reflections about subject matter knowledge (SMK) and instructional practice in the elementary grades. Thirty-three teachers were part of a 5-year professional development program designed to enhance instructional quality and effectiveness to teach English learners.…

While computational biology and bioinformatics became an inherent part of most life science degrees, it remains challenging to encourage students to employ these diverse skills in a practical research context. In this education paper, we present a method to enable students to acquire hands-on skills by the data-driven study of complex biomolecular…

Design2Learn (D2L) is a NYC-based afterschool program aimed at increasing middle school students' interest, engagement, and achievement in science. Designed by ExpandED Schools, D2L centers around three core strategies: (1) collaborative teaching between an in-school science teacher and two afterschool educators; (2) curricular bridging, which…

In this article, we examine whether an inquiry-based, hands-on physics lab can be delivered effectively as a distance lab. In science and engineering, hands-on distance labs are rare and open-ended project labs in physics have not been reported in the literature. Our introductory physics lab at a large Canadian research university features…

This qualitative study explores the in- and out-of-school experiences that could have influenced elementary preservice teachers? beliefs and attitudes toward learning and teaching science. Participants were 126 Latina/o EC-6 preservice teachers in the context of a 16-week undergraduate level elementary methods course. Data sources consisted of…

A shortcoming of Massive Open Online Courses (MOOCs) is the lack of substantive integration of hands-on activities into online classrooms. We conducted a randomised control trial (RCT) in a MOOC where we sent the treatment group at-home lab kits with which they could perform experiments in their own homes. In our intervention research, we found…

Authentic student-led inquiry and exposure to scientific research impact students' science career choices. Given Australian students decline in STEM [science, technology, engineering and mathematics] skills, knowledge of whether such programmes impact student learning is critical. This research examined the short-term impact of an authentic,…

Art and science help students investigate light energy and practice fair testing. With the goal of finding a way to save "Beady Kid" from invisible rays, students used science practices to investigate the transfer of light energy from the Sun. During this art-integrated science lesson presented in this article, upper elementary (grades…

Having high-quality early childhood education programs that prepare children for success in school and later years continues to be an ever increasing national priority. While the "Next Generation Science Standards" ("NGSS") do not provide standards for preschool, there are ample opportunities to use the Standards as a guide to…

A Wolff-Kishner reaction that does not require hydrazine has been developed. The reaction sequence has two steps: formation of a carbomethoxyhydrazone from methyl hydrazinocarboxylate and acetophenone, then decomposition of this intermediate by treatment with potassium hydroxide in triethylene glycol. Purification is by filtration through a plug…
