This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

Inquiry-based learning (IBL) is a student-centered teaching technique that promotes engagement through higher-order thinking, collaboration, and creativity. This study examines the impact of IBL levels on students' interest, motivation, and engagement. Three levels of IBL (traditional, structured, and guided) were implemented in an introductory…

This study's general theme revolves around practical work in chemical education, and its scope is the employment of a novel inquiry strategy combined with a new openness level. We investigate how the controlled positive error, a new device for inquiry activities developed by us, affects undergraduate students' experience of an experiment and…

An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…

Structured collaborative peer teams are widely recognized as a high-impact pedagogy that supports learning outcomes for diverse learners but it can be difficult to implement this pedagogy in an online environment. This communication describes a structure to use collaborative teams to develop and sustain a community of inquiry in an asynchronous…

Many agencies, organizations, and researchers have called for the incorporation of inquiry-based learning in college classrooms. Providing inquiry-based activities in laboratory courses is one way to promote reformed, student-centered teaching in introductory geoscience courses. However, the literature on inquiry has relatively few geoscience…

In this article, the author describes a chemistry gas experiment that she developed with the intent of integrating inquiry and Problem-Based Learning (PBL). The lab activity follows the principles of Ambitious Science Teaching (AST). Teachers (1) engage students with important science ideas, (2) elicit students' ideas while making visible what…

Energy is one of the most complex yet central concepts taught in schools and is featured in the Australian Science Curriculum, as one of the six key organising ideas (Australian Curriculum, Assessment and Reporting Authority (ACARA), 2015). The literature portrays a multitude of complications associated with teaching energy (see Millar, 2005 for a…

The recent revisions to the advanced placement (AP) chemistry curriculum promote deep conceptual understanding of chemistry content over more rote memorization of facts and algorithmic problem solving. For many teachers, this will mean moving away from traditional worksheets and verification lab activities that they have used to address the vast…

This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Studies comparing virtual and physical manipulative environments (VME and PME) in inquiry-based science learning have mostly focused on students' learning outcomes but not on the actual processes they engage in during the learning activities. In this paper, we examined experimentation strategies in an inquiry activity and their relation to…

We present a hands-on, inquiry-based activity exploring how CO[subscript 2] input to seawater affects the skeletons of several species of reef-building corals and other marine organisms by testing for changes in pH and calcium ion concentrations. Originally developed to inspire and recruit high school students in the state of Hawai'i into the…

The history of learning biology through distance education is documented. A review of terminology and unique problems associated with biology instruction is presented. Using published research and their own teaching experience, the authors present recommendations and best practices for managing biology in distance-based formats. They offer ideas…

The authors combined content-driven and inquiry-based lessons into the framework of problem-based learning (PBL). They did this in eight third- through sixth-grade classrooms--two each from grades 3-5, one from sixth grade, and one mixed-grade special education. These older elementary students explored a local problem of lobsters infected by…
