Getting students to use grading feedback as a tool for learning is a continual challenge for educators. This work proposes a method for evaluating student performance that provides feedback to students based on standards of learning dictated by clearly delineated course learning outcomes. This method combines elements of standards-based grading…

Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and…

This study describes how students' intuitions about sampling are informed by extended experiences in investigating local ecosystems. Elementary students in a rural/suburban district in the upper midwest spent a year conducting first-hand comparative field studies of nearby ponds, prairies, and forests. At the close of the term, we conducted…

University laboratory science courses are typically designed to prepare science majors or those who are pursuing health related careers. These courses often do not provide the experiences necessary to improve elementary preservice teacher science teaching efficacy or attitudes and beliefs toward science. This research utilized a university science…

Researchers are trying to develop assessments for inquiry practices to elicit students' deep science learning, but few studies have examined the relationship between students' "doing," i.e. "performance assessment," and "writing," i.e. "open responses," during inquiry. Inquiry practices include generating…

Teaching science as inquiry has been at the forefront of many educational reforms related to teaching science in K-12 settings. However, educators' understandings of the term and practices related to science as inquiry vary. This study examined a group of middle school science teachers' perspectives and practices related to teaching science as…

Practicing scientists' views of science recently have become a topic of interest to nature of science researchers. Using an interview protocol developed by Carey and Smith that assumes respondents' views cohere into a single belief system, we asked 15 research chemists to discuss their views of theories and experimentation. Respondents expressed a…

An experiment based on the sublimation of a solid was introduced in the undergraduate Transport Phenomena course. The experiment required the students to devise their own apparatus and measurement techniques. The theoretical basis, assignment of the experiment, experimental results, and student/instructor observations are described in this paper.…

A detailed rubric initially designed as a scoring instrument for grading APA-style empirical research reports was tested for its ability to help students improve their scientific writing skills. Students who used the rubric while preparing their reports wrote a higher quality report than did students who did not. Students also improved the quality…

Human beings depend on a set of benefits that emerge from functioning ecosystems, termed Ecosystem Services (ES), and make decisions in everyday life that affect these ES. Recent advancements in science have led to an increasingly sophisticated understanding of ES and how they can be used to inform environmental decision-making. Following suit, US…

Facilitating students' deep-strategy behaviors and positive learning performances of science inquiry is an important and challenging educational issue. In this study, a contextual science inquiry approach is proposed for developing a 3D experiential game to cope with this problem. To evaluate the impacts of the game on students' science learning…

This author wanted to begin her 10-grade biology course with an authentic inquiry that included a review of equipment use, investigation methods, and critical thinking skills. She also wanted to engage students in the practice of science while teaching biological core ideas and crosscutting concepts. She was at a loss as to what that inquiry might…

Researchers taking a domain-general approach to the development of scientific reasoning long thought that the ability to engage in scientific reasoning did not develop until adolescence. However, more recent studies have shown that preschool children already have a basic ability to evaluate evidence and a basic understanding of experimentation.…

Inquiry-based science interventions aim to improve students' science proficiency by helping them understand scientific processes. In these interventions, students conduct hands-on investigations of science concepts and everyday phenomena, construct explanations for what they observe, consider alternative explanations, and communicate and justify…

The intermolecular forces activity presented in this article is designed to foster concept-building through students' use of concrete, manipulative objects, and it was developed to be pedagogically sound. Data analysis via pre- and posttesting and subsequent exam questions indicated that students who had the opportunity to participate in the…
