Research shows that that children learn science and engineering subjects best by engaging from an early age in the kinds of practices used by real scientists and engineers. By doing science and engineering, children not only develop and refine their understanding of the core ideas and crosscutting concepts of these disciplines, but can also be…

Professionalism is a required curricular component in accredited medical laboratory science (MLS) programs in the United States and is a critical element for career success and optimal patient care. A standardized definition of professionalism in MLS, however, has yet to be established. This poses a challenge to MLS programs when pertaining to…

Molecular representations that show chemical bonding are ubiquitous in general and organic chemistry. These help in communicating chemistry concepts that are fundamental to understanding "how" and "why" molecules interact. The goal of this dissertation work is to offer an evidence-based report on the affordances and limitations…

Teachers must enhance their teaching skills in accordance with institutional policies at higher education institutions. This research aims to determine effective professional development techniques for biology teachers in higher education. The modified OZON form (cro. obrazac za opažanje nastave, teaching observation form) facilitated…

STEM fields, such as physics, increasingly rely on complex programs to analyse large datasets, thus teaching students the required programming skills is an important component of all STEM curricula. Since undergraduate students often have no prior coding experience, they are reliant on error messages as the primary diagnostic tool to identify and…

Knowledge related to photochemistry has been gradually introduced as a part of chemistry courses at both undergraduate and postgraduate levels. However, due to their complex conceptual principles, limited class time, and tedious experimental setup and methodologies, students tend to encounter difficulties in understanding the concepts and…

Reading and understanding scientific literature is an essential skill for any scientist to learn. While students' scientific literacy can be improved by reading research articles, an article's technical language and structure can hinder students' understanding of the scientific material. Furthermore, many students struggle with interpreting graphs…

Modeling an inter-ring torsional profile of a simple2,2'-bithiophenemolecule has been used to illustrate the main concepts associated with basic molecular modeling within an introductory course in a master's degree on computational modeling. The methodology proposed in the activity has been used to guide and train the student along the classical…

Learning needs to be well planned so that it can take place in accordance with the objectives to be achieved. This planning can be poured into the learning implementation plan (RPP) prepared by the teacher. Therefore, this study aims to describe the competence of prospective chemistry teacher students to prepare lesson plans using a scientific…

Co-curricular service-learning has increasingly attracted participants from students as it can enrich their experience of learning chemistry, among others. An example is "Kimikamahika," wherein chemistry students from a Catholic university in the Philippines volunteer in public schools, orphanages, daycare centers, and local…

Teachers select multiple representations and adopt multiple visualization approaches in supporting their students to make meaning of chemical phenomena. Representational competence underpins students' construction of their mental models of concepts thus it is important that teachers consider this while developing instructional resources. In…

Fernández-Chapou and colleagues analyzed projectile trajectories and showed an elliptic property hidden in them. For that analysis, they considered projectiles shot from a point with a common value of speed and different angles of projection. Such projectile paths exhibit some interesting characteristics. For example, pairs of projectiles with…

A power supply is needed to maintain the function of a computer, heat is needed to keep food from cooling down, and a force is needed to maintain motion. Those are notions that seem very natural to many people as they are based on everyday experiences. However, when it comes to motion, it is not force that maintains motion but momentum. Students…

Models were prepared by 3D printing that can be used to demonstrate the operations required for the study of molecular symmetry. The models were designed to emphasize the order and locations of rotation axes and to clearly illustrate the more abstract reflection and improper rotation axes. The models were well-received by students in a course on…

The ability to develop and use models to explain phenomena is a key component of the "Next Generation Science Standards", and without examples of what modeling instruction looks like in the reality of classrooms, it will be difficult for us as a field to understand how to move forward in designing curricula that foreground the practice…
