Students' understanding about analogy was investigated after a CORE learning cycle general chemistry experiment. CORE (Chemical Observations, Representations, Experimentation) is a new three-phase learning cycle that involves (phase 1) guiding students through chemical observations while they consider a series of open-ended questions, (phase 2)…

Quick and real-time plotting equations using the Winplot software can be employed to create accurate hybrid atomic orbitals without complicated scripting. Performing this task on their own, students can more easily understand and remember hybrid atomic orbitals, in terms of shape and orientation.

This paper describes a student designed experiment using titrations involving conductivity measurements to identify unknown acids as being either HCl or H[subscript 2]SO[subscript 4], and to determine the concentrations of the acids, thereby improving the utility of standard acid-base titrations. Using an inquiry context, students gain experience…

The physiology of breath holding is complex, and voluntary breath-hold duration is affected by many factors, including practice, psychology, respiratory chemoreflexes, and lung stretch. In this activity, we outline a number of simple laboratory activities or classroom demonstrations that illustrate the complexity of the integrative physiology…

A "tessellation" is a pattern of geometric shapes that fulfills three conditions: (1) No gaps exist between the shapes; (2) The shapes do not overlap; and (3) The pattern can go on forever in all directions. Tilings (such as tiling a floor) are familiar to children and provide a rich resource at all grade levels for learning many…

Our study of pre-service teachers' (PSTs) inquiry projects includes two levels of practitioner-research: on one level, we examine the research questions PSTs pose about their classrooms; and on the second, the study is an action-research investigation of our own practice in teaching PSTs both pedagogical and inquiry practices. We study PSTs'…

A discovery-based Grignard experiment for a second-year undergraduate organic chemistry course is described. The exclusive Grignard reagent formed by the reaction of 1-bromo-4-fluorobenzene (1) with Mg is 4-fluorophenylmagnesium bromide (2), which is treated with either benzophenone or CO[subscript 2] to produce the corresponding fluorinated…

The aim of this review is to identify specific types of guidance for supporting student use of online labs, that is, virtual and remote labs, in an inquiry context. To do so, we reviewed the literature on providing guidance within computer supported inquiry learning (CoSIL) environments in science education and classified all identified guidance…

The study we have carried out aims to characterize 15-to 16-year-old students' learning progressions throughout the implementation of a teaching-learning sequence on the acoustic properties of materials. Our purpose is to better understand students' modeling processes about this topic and to identify how the instructional design and actual…

This inquiry-based experiment is designed for organic or biochemistry undergraduate students to deduce the identity of phospholipids extracted from chicken eggs and dietary supplements. This is achieved using thin-layer chromatography (TLC) data, a series of guided questions of increasing complexity, and provided relative retention factor (Rf)…

A mind mapping approach to evaluation called Ripple Effects Mapping (REM) has been developed and used by a number of Extension faculty across the country recently. This article describes three approaches to REM, as well as key differences and similarities. The authors, each from different land-grant institutions, believe REM is an effective way to…

The concept of belonging is widely recognised as a fundamental part of human development and a key element of early childhood curricula. The research presented here explores the role of singing in the development of children's sense of belonging in a day nursery for children aged from six months to two years. The research design incorporated…

The College, Career, and Civic Life (C3) Framework from the National Council for Social Studies (NCSS) features an inquiry approach to teaching K-12 social studies in which social studies standards are organized into an "inquiry arc." Inquiry in elementary economics is often underused in practice (Laney 2001). This study describes how a…

The Industrial Revolution is the subject of one of the high school inquiries of the New York State Toolkit. Social Education presents the following excerpts from the inquiry as an example of a typical Toolkit lesson. The supporting questions include: (1) Where did people move to and from during the Industrial Revolution?; (2) How did daily life…

This study explored secondary agriculture education as practiced by four teachers and sought to examine and describe how they interpreted and practiced the Biological Science Applications in Agriculture (BSAA) curriculum. The following questions were examined: (a) What does BSAA teaching look like in practice? (b) How do teachers perceive their…
