We describe a guided-inquiry laboratory experiment for instrumental analysis in which our students test an improved protocol for the recycling of silver chloride to produce nontoxic waste. Students are provided with samples of silver chloride that they created as waste products in a previous lab experiment and tasked with performing a stepwise…

Writing is an integral part of the process of science. In the undergraduate physics curriculum, the most common place that students engage with scientific writing is in lab classes, typically through lab notebooks, reports, and proposals. There has not been much research on why and how we include writing in physics lab classes, and instructors may…

Science assessments should evaluate the full complement of inquiry practices (NGSS, 2013). Our previous work has shown that a large proportion of students' open responses did not match their scientific investigations (Li et al., 2017a). The present study both unpacks and compares the sub-components underlying students' performance for…

In this study, we randomly assigned 69 Grade 4 students to a writing-to-learn treatment (n = 23), comparison (n = 23), or no-treatment control (n = 23). Treatment and comparison students completed a science experiment involving balance. During the experiment, treatment students wrote four short responses and an extended response to document their…

The present paper focuses on the acquisition of hedging techniques by first-year undergraduate students at the University of Tokyo in Japan. One of the major difficulties faced by aspiring science writers lies in positioning their arguments in relation to the preexisting literature. This originates from the fact that writing in the field of…

Argument-Driven Inquiry (ADI) is an instructional model that enables science teachers to transform a traditional laboratory activity into a short integrated instructional unit. To illustrate how the ADI instructional model works, this article describes an ADI lesson developed for a 10th-grade chemistry class. This example lesson was designed to…

The purpose of this study was to reconstruct writers' reasoning process as reflected in their written texts. The codes resulting from the text analysis were related to cognitive operations, ranging from simple to more sophisticated ones. The sequence of the cognitive operations as the text unfolded represents the writer's cognitive pathway at the…

Discusses the use of science process skills to help students think positively about writing assignments. Examines the four language arts skills of narration, description, explanation, and persuasion, as used in writing about hands-on science activities. (MDH)
