Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…

Purpose: The purpose of this paper is to present the results of measuring a sample of engineering students' perceived achievement of complex thinking at different stages of their professional training. This study intended to analyze and predict the differences in the self-perception of achieved complex thinking competency by gender, semester,…

Students develop process skills through repeated practice of data interpretation, problem solving, and critical thinking. The primary literature provides a rich source of data and application problems to engage students in this practice within the context of chemistry content knowledge. However, most existing classroom activities based on the…

Challenge Statement: Laboratory classes are indispensable in the teaching of biomedical engineering education, offering students invaluable hands-on experience and opportunities for practical application of theoretical knowledge. However, without a deep understanding of the underlying principles, students may find themselves merely going through…

Evidence-based reasoning and critical thinking are two crucial scientific abilities of students, sharing a close relationship with each other critical thinking is not just randomly refuting but a logical-reasoning thinking based on solid evidence. However, in real teaching circumstances of experiment classes, students easily directly accept the…

Scientific/chemical literacy is currently the goal of science education in many countries. Students' chemical literacy can be developed through an innovative learning strategy that explicitly direct student learning to aspects of chemical literacy. This research aimed to examine the effectiveness of SOIE (Strengthening, Orientation, Investigation,…

Scientific thinking is considered as a cognitive process in which the underlying causes of a basic problem are solved. It is of great importance for teachers to have scientific thinking skills to improve their professional lives, to create effective learning environments, to continuously question the events and processes in the classroom, to carry…

Background: The competencies for the 21st century are defined as a broad and interrelated system of knowledge, skills, values and attitudes enabling the full application of man in personal and professional life. Regarding the science education competencies combining science and scientific knowledge, as well as skills such as inquiry, critical…

Today science teachers are expected to understand the nature of environmental education, and be competent in skills, methods, and procedures relevant to a science discipline. The purpose of this research was to explore pre-service science teachers' views with regard to environmental education, investigation conducted during a freshwater ecosystem…

We reported a redesign of a physical chemistry laboratory course (CHEM 166) for our chemistry majors at the University of Vermont carried out during the COVID-19 pandemic. We started to teach this course after a curriculum reform, which split an upper-division undergraduate laboratory course into physical and analytical chemistry laboratories. To…

The development of good learning resources on inquiry learning model with science literacy as a strategy to facilitate active learning has become a trend in education. Critical thinking ability is needed as a strategy to build students competencies in problem solving and discovery as required in science learning. This study aims to develop a set…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Fisheries scientists make sure that fish populations ("fisheries") are managed properly, neither over- or under-utilized, to maintain long-term economic and ecological stability. Scientists collect data and conduct surveys to determine fish populations, and then make recommendations about how many fish may be caught by commercial and…

In today's science classrooms, with the integration of the Next Generation Science Standards (NGSS), teachers are encouraged to guide instruction through real-world phenomena and promote critical thinking through inquiry-based learning that helps students learn the reasoning and practical skills of scientists, rather than just rote memorization of…

Assessment, including course exams, clearly indicates to students what learning goals they are expected to master in a certain course. However, most of these assessments tend to focus on generating a correct answer rather than on the type of reasoning or skills used to arrive at the answer. If educators value skills in addition to the correctness…
