The rhetorical argument that laboratory courses are crucial for training skilled STEM practitioners is ill-evidenced in teaching practice. The arduous task of implementing instructor-led skill assessment in large-cohort courses and persistent student "disengagement" from its educative goals are some obstacles. This study emphasized the…

The results of an earlier empirical research study on modifying 'step-by-step' instructions to practical activities requiring one or more steps of the experiments to be designed by students initiated a longitudinal study to investigate the effectiveness of the approach for younger students and over a period of time. The longitudinal study that…

Chemists refer to chemical phenomena on different representational levels--macroscopic, symbolic, and submicroscopic--which are directly related and connected to each other. Especially in the laboratory, students have to reason about various mechanistic features at the submicroscopic level and connect them in a meaningful way to make sense of the…

In the field of science education, laboratory learning environment has gained renewed interest in the recent decade. This study aimed to investigate the relationships among students' conceptions of science laboratory learning, perceptions of the science laboratory learning environment, and their academic self-efficacy in science learning by…

STEM is an educational practice to integrate science, mathematics, engineering, and technology within the formal and informal context and it provides practical opportunities for the child to make sense of the world holistically. Moreover, the most important benefit of STEM activities for children, including engineering design, is to improve or…

Biology learning, especially the topic of plant physiology, requires Higher Order Thinking Skills (HOTS). This ability needs to be improved with HOTS based teaching materials. The teaching materials, however, have not been developed, especially those in plant physiology topic. Students' HOTS in biology learning still requires an improvement as…

Practical work is critical to understanding science concepts. A case study was carried out to understand teachers' perceptions regarding practical work in Mankweng Circuit, South Africa. Four Grade 11 Physical Science teachers from different high schools were purposively selected. Data were collected through interviews, classroom observations, and…

Competence-based, science e-testing (CBSeT) is a novel external assessment tool which provides feedback to science teachers about their students' competence-based skills, thereby giving relevant assessment information which teachers could potentially use in their teaching practice. The aim of this study was to determine the extent to which…

The 'Moss Safari' activity was developed to assist with knowing which organisms to look for when observing a drop of water squeezed from moss for the first time. In this case study, the activity was introduced online to 34 trainee science teachers. This was followed by a post-session questionnaire evaluating their experience of the Moss Safari.…

The current mixed method study examined a Teacher Leadership Program (TLP) to determine to what extent participating teachers had changes in content knowledge (CK), practices, leadership skills, and leadership knowledge. The purpose was to determine if this program could be utilized to suggest a sustainable model for improving science education by…

This study explores how an afterschool science program for girls that uses a curriculum written by female scientists/science educators and highlights the contributions of women in science, technology, engineering, and mathematics (STEM) fields affects girls' perception of scientists, confidence in their science skills, belief in their ability to…

Practical classes are an important and essential part of undergraduate programs in Chemical Engineering, as each experiment provides an opportunity to reinforce the theory of discrete unit operations that are taught elsewhere in the course. While an expensive pedagogical method, when practical sessions are delivered well, they can be one of the…

This study aims to determine the effects of activities based on the Prediction-Observation-Explanation [POE] strategy on sixth grade students' understanding of the particulate nature of matter. The study was carried out with a sixth grade group consisting of 41 students from a middle school in an eastern city. Three activities were carried out…

Building on Carey and Smith's work on epistemology of science, this study characterized elementary students' scientific epistemology from the role-of-idea and theory-building perspective. The participants included 102 elementary students in Hong Kong. Open-ended questions and coding schemes were developed to examine and characterize their…

Attaining the vision for science teaching and learning emphasized in the Framework for K-12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS-inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating…
