Measuring Student Engagement in the Undergraduate General Chemistry Laboratory
Peer reviewed Peer reviewed
Direct linkDirect link
Smith, K. Christopher; Alonso, Valeria – Chemistry Education Research and Practice, 2020
In this study a survey was developed to investigate students' engagement during general chemistry laboratory sessions. Aspects of engagement surveyed included cognitive, behavioral, and emotional engagement, and the survey items were focused on activities during the pre-laboratory introduction, laboratory procedures, and data collection.…

Smith, K. Christopher; Sepulveda, Adrian – Chemistry Education Research and Practice, 2018
In this study 635 general chemistry I and general chemistry II students completed a 40-item Likert-scale survey on their opinions of various practices, including some academically dishonest practices, that might occur in the general chemistry laboratory. The practices surveyed were focused on areas including preparation before coming to the…

Smith, K. Christopher; Villarreal, Savannah – Chemistry Education Research and Practice, 2015
In this reply to Elon Langbeheim's response to an article recently published in this journal, authors Smith and Villarreal identify several types of general chemistry students' misconceptions concerning the concept of particle position during physical change. They focus their response on one of the misconceptions identified as such: Given a solid…

Using Animations in Identifying General Chemistry Students' Misconceptions and Evaluating Their Knowledge Transfer Relating to Particle Position in Physical Changes
Peer reviewed Peer reviewed
Direct linkDirect link
Smith, K. Christopher; Villarreal, Savannah – Chemistry Education Research and Practice, 2015
This article reports on the types of views and misconceptions uncovered after assessing 155 freshman general chemistry students on the concept of particle position during the reversible physical change of melting, using the Melting Cycle Instrument, which illustrates particulate-level representations of a melting-freezing cycle. Animations…

Smith, K. Christopher; Nakhleh, Mary B. – Chemistry Education Research and Practice, 2011
Undergraduate and graduate students' predictions and submicroscopic level explanations for the melting of four materials (salt, chalk, sugar, and butter), and for the mixing of these solutes in two solvents (water and cooking oil) were collected. Twenty-three undergraduate students and seven graduate students participated in the study, and data…

An Expanded Framework for Analyzing General Chemistry Exams
Peer reviewed Peer reviewed
Direct linkDirect link
Smith, K. Christopher; Nakhleh, Mary B.; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2010
This paper describes an expanded framework to aid chemical educators in constructing exams for their courses. The framework has three primary levels: definition, algorithmic, and conceptual. These primary levels have often been used in chemical education research to analyze and describe exam questions, but in this study the definition,…
