This study made a preliminary attempt to conduct a needs assessment of teachers' utilization of the SSI-based approach in teaching Science by exploring Filipino teachers' awareness, perceived need, readiness, and willingness. It also aimed to determine which among the demographic profiles of the teachers had significant differences in their…

Colleges throughout the United States typically expect their students to take at least one course in the sciences to fulfill liberal studies curriculum requirements. For nonscience majors, the choice of science class can include introductory chemistry, introductory biology, and astronomy, among others. Based upon interactions both in and out of…

Science education researchers and curriculum documents have advocated scientific inquiry for more than six decades; however, inconsistent findings concerning its effects on students' learning outcomes have been revealed in recent analyses of large-scale international assessment data (e.g., the Programme for International Student Assessment…

The area of application of electrospray ionization mass spectrometry (ESI-MS), usually coupled with liquid chromatography, seems to be much larger than those of any other ionization method. It gives rise to the demand for new teaching methods that would effectively help students to master the principles of working with and making full use of the…

Explicitly attending to justice in science teaching and learning is long overdue. Here, we examined the professional teacher identity development of 13 science teachers as they collaborated in networked professional learning communities (PLCs) to implement and revise a culture-setting unit focused on the science of COVID and engaging in…

Purpose: This research paper aims to provide information about certified learning apps for biological education and gave an ordered list of all learning apps currently used by Austrian biology teachers in the classroom, which should serve as an overview for all biology teachers. In addition, the (currently little known) certification process of…

The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

Cultivating in preservice science teachers (PSTs) the competence required to teach scientific models and modeling is a valued outcome of teacher preparation programs. However, science teacher educators face inherent tensions when designing and implementing teacher preparation experiences to achieve this outcome. In this systematic review, we first…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

Micropaleontology is a critical tool for determining the ages of geologic records, reconstructing ancient environments, and monitoring modern ecosystem health. However, most students are not exposed to micropaleontology in their college coursework. To enable non-expert instructors to integrate microfossil identification training in their…

The BSCS 5E Instructional Model, an elaboration of the well-known and accepted three-part learning cycle, is a five-part approach to incorporating inquiry-based, active learning in the classroom. Developed in 1987 by the Biological Sciences Curriculum Study, "the 5Es" is a popular K-20 instructional practice, and as such, the Biological…

Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in…

Curriculum reform worldwide has often reflected changing perspectives on the teaching and learning of science. Such perspectives underline the notion that not only the teaching of science content knowledge is relevant but also the aims and methods scientists use to further their knowledge and the social context in which science is applied. We call…

Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…
