By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

Proteins must interact with a variety of other cellular components to properly perform their functions. We have developed a series of five experiments based on the robust bacterial single-stranded DNA binding protein (SSB) to characterize both known and unknown protein-protein and protein-DNA interactions. Students work in groups to generate and…

It is important that students understand the role the ocean plays in mitigating climate change, and how every person on this planet is uniquely connected to the ocean. Identifying these connections can be challenging for students in rural or underserved areas, many of whom do not live by, or interact with, the ocean. Through the use of the board…

In this study, a new model termed as "Flexible Inquiry Based Science Teaching", which is developed using the framework of the inquiry approach is proposed. Science teachers (n=2) who participated in the study were instructed on the inquiry approach and their in-class activity applications were examined. The "electricity module"…

This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Science instruction is a critical aspect of early learning. Teachers can support young children's learning about scientific concepts through the use of the Universal Design for Learning (UDL) framework, which is a proactive approach to instructional planning that helps ensure success for all learners. This teaching techniques article offers…

In this teaching laboratory, the students are directed in an exercise that involves designing and performing an experiment to determine estrogen's role in regulating delayed implantation (diapause) in female rats. To encourage active participation by the students, a discussion question is provided before the laboratory exercise in which each…

This study developed a web-based multimedia assessment system (WMA system) and applied it to science laboratory instruction. The goal was to improve students' knowledge acquisition under science laboratory instruction. The developed system enabled learners to perform self-assessments by responding to multimedia technology test items online. The…

This study investigated the management of teaching and assessment of the "qualified to be progressed" learners (QP) for quality learning and teaching. Mixed methods approach was adopted. Random and purposive sampling were used to select teachers and School Management Team (SMT) member respectively who formed the study sample. The study…

How to help teachers to design teaching plan for raising student's competency at secondary school in Laos is now of great concern. On the other hand, teachers teach sciences almost by lecturing theoretical only. They rarely explain the problems based on actual phenomena that occur in pupils' daily life nor do experiment during the class. Thus, one…

Analytical method transfer (AMT) and dissolution testing are important topics required in industry that should be taught in analytical chemistry courses. Undergraduate students in senior level analytical chemistry laboratory courses at Kennesaw State University (KSU) and St. John Fisher College (SJFC) participated in development, validation, and…

The laboratory is a mainstay in STEM education, promoting the development of critical thinking skills, dexterity, and scientific curiosity. The goals in the laboratory for nonchemistry, prehealth majors, though, could be distinguished from those for chemistry majors. In service courses such as organic chemistry, much laboratory time is often spent…

Tomlinson's explanation of Artful Teaching and her 2017 expansion of this concept The Five Key Elements of Differentiation provide the theoretical framework of this examination of the need for science investigations in elementary schools. The Artful Teaching framework uses an equilateral triangle with vertices labeled The Teacher, The Student, and…

Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed…

The physics curriculum is usually defined by content but this does not provide students with an authentic experience of the subject. An alternative is that physics is defined more as a way of thinking and this idea is explored in terms of the purposes of physics education, assessment and the relationship of the subject with other disciplines. A…
