Cruz-Ramírez de Arellano, Daniel; Towns, Marcy H. – Chemistry Education Research and Practice, 2014
Organic chemistry is an essential subject for many undergraduate students completing degrees in science, engineering, and pre-professional programs. However, students often struggle with the concepts and skills required to successfully solve organic chemistry exercises. Since alkyl halides are traditionally the first functional group that is…

Siweya, Hlengani J.; Letsoalo, Peter – Chemistry Education Research and Practice, 2014
This study investigated whether formative assessment is a predictor of summative assessment in a university first-year chemistry class. The sample comprised a total of 1687 first-year chemistry students chosen from the 2011 and 2012 cohorts. Both simple and multiple linear regression (SLR and MLR) techniques were applied to perform the primary aim…

Salah, Hazzi; Dumon, Alain – Chemistry Education Research and Practice, 2014
The concept of covalent bonding is characterized by an interconnected knowledge framework based on Lewis and quantum models of atoms and molecules. Several research studies have shown that students at all levels of chemistry learning find the quantum model to be one of the most difficult subjects to understand. We have tried in this paper to…

Dhindsa, Harkirat S.; Treagust, David F. – Chemistry Education Research and Practice, 2014
As an important subject in the curriculum, many students find chemistry concepts difficult to learn and understand. Chemical bonding especially is important in understanding the compositions of chemical compounds and related concepts and research has shown that students struggle with this concept. In this theoretical paper based on analysis of…

Robertson, Amy D.; Shaffer, Peter S. – Chemistry Education Research and Practice, 2014
On the basis of responses to written questions administered to more than one thousand introductory chemistry students, we claim that students often rotely apply memorized combustion rules instead of reasoning based on explanatory models for what happens at the molecular level during chemical reactions. In particular, many students argue that…

Allenbaugh, R. J.; Herrera, K. M. – Chemistry Education Research and Practice, 2014
Determining student readiness for gateway chemistry courses and providing underprepared students effective remediation are important as student bodies are growing increasingly diverse in their precollege preparation. The effectiveness of the ACT Mathematics Test and the Whimbey Analytical Skills Inventory (WASI) in predicting student success in…

Clauss, Allen D.; Nelsen, Stephen F.; Ayoub, Mohamed; Moore, John W.; Landis, Clark R.; Weinhold, Frank – Chemistry Education Research and Practice, 2014
We describe the logical flaws, experimental contradictions, and unfortunate educational repercussions of common student misconceptions regarding the shapes and properties of lone pairs, inspired by overemphasis on ''valence shell electron pair repulsion'' (VSEPR) rationalizations in current freshmanlevel chemistry textbooks. VSEPR-style…

Villalta-Cerdas, Adrian; Sandi-Urena, Santiago – Chemistry Education Research and Practice, 2014
Self-explaining refers to the generation of inferences about causal connections between objects and events. In science, this may be summarised as making sense of how and why actual or hypothetical phenomena take place. Research findings in educational psychology show that implementing activities that elicit self-explaining improves learning in…

Bain, Kinsey; Moon, Alena; Mack, Michael R.; Towns, Marcy H. – Chemistry Education Research and Practice, 2014
We review previous research on the teaching and learning of thermodynamics in upper-level, undergraduate settings. As chemistry education researchers we use physical chemistry as a context for understanding the literature. During our synthesis four themes of research emerged: factors that influence student success in learning thermodynamics,…

Chamberlain, Julia M.; Lancaster, Kelly; Parson, Robert; Perkins, Katherine K. – Chemistry Education Research and Practice, 2014
We studied how students engaged with an interactive simulation in a classroom setting and how that engagement was affected by the design of a guiding activity. Students (n = 210) completed a written activity using an interactive simulation in second semester undergraduate general chemistry recitations. The same simulation--PhET Interactive…

Nyachwaya, James M.; Wood, Nathan B. – Chemistry Education Research and Practice, 2014
That different levels of representation are important for complete understanding of chemistry is an accepted fact in the chemistry education community. This study sought to uncover types of representations used in given physical chemistry textbooks. Textbooks play a central role in the teaching and learning of science (chemistry), and in some…

Teo, Tang Wee; Tan, Kim Chwee Daniel; Yan, Yaw Kai; Teo, Yong Chua; Yeo, Leck Wee – Chemistry Education Research and Practice, 2014
In this paper, we define flip teaching as a curricular platform that uses various strategies, tools, and pedagogies to engage learners in self-directed learning outside the classroom before face-to-face meetings with teachers in the classroom. With this understanding, we adopted flip teaching in the design and enactment of one Year 1 and one Year…

Gillette, Gabriel; Sanger, Michael J. – Chemistry Education Research and Practice, 2014
This study analysed the distribution of questions from the gas law chapters of four high school and four college chemistry textbooks based on six variables--Book Type (secondary "versus" introductory college), Cognitive Skill (lower-order "versus" higher-order), Question Format (calculation "versus" multiple-choice…

Gulacar, Ozcan; Bowman, Charles R. – Chemistry Education Research and Practice, 2014
If the goal of teaching is to help students understand a subject, teaching cannot begin until student difficulties with a subject are understood. In order to create a guide for assessing student difficulties with chemistry material, students were asked to rate exam questions on three factors: problem difficulty, familiarity, and self-confidence.…

Becker, Nicole; Rasmussen, Chris; Sweeney, George; Wawro, Megan; Towns, Marcy; Cole, Renee – Chemistry Education Research and Practice, 2013
In college level chemistry courses, reasoning using molecular and particulate descriptions of matter becomes central to understanding physical and chemical properties. In this study, we used a qualitative approach to analyzing classroom discourse derived from Toulmin's model of argumentation in order to describe the ways in which students develop…
