Test-Enhanced Learning: The Potential for Testing to Promote Greater Learning in Undergraduate Science Courses

Testing within the science classroom is commonly used for both formative and summative assessment purposes to let the student and the instructor gauge progress toward learning goals. Research within cognitive science suggests, however, that testing can also be a learning event. We present summaries of studies that suggest that repeated retrieval can enhance long-term learning in a laboratory setting; various testing formats can promote learning; feedback enhances the benefits of testing; testing can potentiate further study; and benefits of testing are not limited to rote memory. Most of these studies were performed in a laboratory environment, so we also present summaries of experiments suggesting that the benefits of testing can extend to the classroom. Finally, we suggest opportunities that these observations raise for the classroom and for further research.Almost all science classes incorporate testing. Tests are most commonly used as summative assessment tools meant to gauge whether students have achieved the learning objectives of the course. They are sometimes also used as formative assessment tools—often in the form of low-stakes weekly or daily quizzes—to give students and faculty members a sense of students’ progression toward those learning objectives. Occasionally, tests are also used as diagnostic tools, to determine students’ preexisting conceptions or skills relevant to an upcoming subject. Rarely, however, do we think of tests as learning tools. We may acknowledge that testing promotes student learning, but we often attribute this effect to the studying students do to prepare for the test. And yet, one of the most consistent findings in cognitive psychology is that testing leads to increased retention more than studying alone does (Roediger and Butler, 2011 ; Roediger and Pyc, 2012 ). This effect can be enhanced when students receive feedback for failed tests and can be observed for both short-term and long-term retention. There is some evidence that testing not only improves student memory of the tested information but also ability to remember related information. Finally, testing appears to potentiate further study, allowing students to gain more from study periods that follow a test. Given the potential power of testing as a tool to promote learning, we should consider how to incorporate tests into our courses not only to gauge students’ learning, but also to promote that learning (Klionsky, 2008 ).We provide six observations about the effects of testing from the cognitive psychology literature, summarizing key studies that led to these conclusions (see

Yer Doin’ it Wrong: How NOT to Interact with Vendors,Publishers, or Librarians

Three librarians who have extensive experience working in libraries or for publishers, vendors, or consortia presented an informal discussion on librarian–vendor relationships. The audience was encouraged to participate. Problems were articulated; speakers and audience members contributed suggestions for better approaches or behaviors when handling difficult situations.     

#MeToo,sexual harassment: an article,a forum,and a dream for the future

#MeToo has breathed new life into the women’s movement and especially into understanding and rectifying sexual harassment, abuse and assault. It has galvanized activists around the globe. And it has placed thousands of stories of the harassed in full view of the public. Sexual harassment, abuse and assault may occur within the organizational context or beyond; but sexual harassment, in particular has been legally labeled an organizational phenomenon. With this in mind, Robin Clair frames the early part of this article around the most recent organizational communication theories (see the appendix for an overview of these theories). Following the essay is a forum, in which invited scholars address questions related to the #MeToo movement.     

THE BULLYING DYNAMIC: PREVALENCE OF INVOLVEMENT AMONG A LARGE‐SCALE SAMPLE OF MIDDLE AND HIGH SCHOOL YOUTH WITH AND WITHOUT DISABILITIES

Bullying has been the topic of much debate and empirical investigations over the past decade. Contemporary literature contends that students with disabilities may be overrepresented within the bullying dynamic as both perpetrators and victims. Unfortunately, prevalence rates associated with the representation of students with disabilities is limited due to measurement, disability status identification, and definition issues. The present study attempted to address these issues by assessing the prevalence rates of specific subgroups of students with disabilities in a large‐scale cross‐sectional study with 13,325 students without disabilities and 1,183 students with disabilities in Grades 6 through 12. Results suggest that overall, students with disabilities reported proportionally higher rates of bullying, fighting, relational aggression, victimization, online victimization, and relational victimization than did their peers without disabilities. These findings suggest that schools must begin to establish targeted interventions to support skill development based on characteristics associated with specific disability identification.     

Intimate partner violence during infancy and cognitive outcomes in middle childhood: Results from an Australian community-based mother and child cohort study

The cognitive functioning of children who experience intimate partner violence (IPV) has received less attention than their emotional-behavioral outcomes. Drawing upon data from 615 (48.4% female) 10-year-old Australian-born children and their mothers (9.6% of mothers born in non-English speaking countries) participating in a community-based longitudinal study between 2004 and 2016, this study examined the associations between IPV in infancy and cognition in middle childhood (at age 10). Results showed that IPV in the first 12 months of life was associated with lower general cognitive ability and poorer executive attention but not working memory skills. IPV in middle childhood (in the 10th year postpartum) was not associated with cognition. This study provides evidence for the long-term impact of early life exposure to IPV on children's cognition, and points to the importance of early intervention to optimize development.

Changes in children’s anger,sadness, and persistence across blocked goals: Implications for self-regulation

The current study took a person-centered approach to examine the heterogeneity of changes in children’s emotions and persistence during a goal-blocking task and examined how different profiles of emotions and persistence related to children’s self-regulation. Children’s anger, sadness, and persistence were rated in a goal-blocking task in toddlerhood (T1; N = 140, 72 boys, M_age = 2.67 years, 90.7% White) and preschool (T2). Children’s self-regulation, specifically sustained attention and engagement, was assessed at T1, T2, and early school-age (T3) from 2005 to 2012. Growth mixture modeling revealed two classes of children at T1 and three classes at T2 with different patterns of anger, sadness, and persistence. Children’s classification at T2, but not T1, significantly predicted their sustained attention and engagement both concurrently and longitudinally.     

The Nature of Scientific Explanation: Examining the perceptions of the nature,quality, and “goodness” of explanation among college students,science teachers,and scientists

Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform efforts. Nonetheless, there is a dearth of research on conceptualizing explanation in science education. Using a philosophically guided framework—the Nature of Scientific Explanation (NOSE) framework—the study aims to elucidate and compare college freshmen science students', secondary science teachers', and practicing scientists' scientific explanations and their views of scientific explanations. In particular, this study aims to: (1) analyze students', teachers', and scientists' scientific explanations; (2) explore the nuances about how freshman students, science teachers, and practicing scientists construct explanations; and (3) elucidate the criteria that participants use in analyzing scientific explanations. In two separate interviews, participants first constructed explanations of everyday scientific phenomena and then provided feedback on the explanations constructed by other participants. Major findings showed that, when analyzed using NOSE framework, participant scientists did significantly “better” than teachers and students. Our analysis revealed that scientists, teachers, and students share a lot of similarities in how they construct their explanations in science. However, they differ in some key dimensions. The present study highlighted the need articulated by many researchers in science education to understand additional aspects specific to scientific explanation. The present findings provide an initial analytical framework for examining students' and science teachers' scientific explanations.
