Can I Have Your Recipe? Using a Fidelity of Implementation (FOI) Framework to Identify the Key Ingredients of Formative Assessment for Learning

For decades, formative assessment has been identified as a high-impact instructional practice that positively affects student learning. Education reform documents such asVision and Change: A Call to Actionexpressly identify frequent, ongoing formative assessment and feedback as a key instructional practice in student-centered learning environments. Historically, effect sizes between 0.4 and 0.7 have been reported for formative assessment experiments. However, more recent meta-analyses have reported much lower effect sizes. It is unclear whether the variability in reported effects is due to formative assessment as an instructional practice in and of itself, differences in how formative assessment was enacted across studies, or other mitigating factors. We propose that application of a fidelity of implementation (FOI) framework to define the critical components of formative assessment will increase the validity of future impact studies. In thisEssay, we apply core principles from the FOI literature to hypothesize about the critical components of formative assessment as a high-impact instructional practice. In doing so, we begin the iterative process through which further research can develop valid and reliable measures of the FOI of formative assessment. Such measures are necessary to empirically determine when, how, and under what conditions formative assessment supports student learning

Lighten the Load: Scaffolding Visual Literacy in Biochemistry and Molecular Biology

The development of scientific visual literacy has been identified as critical to the training of tomorrow's scientists and citizens alike. Within the context of the molecular life sciences in particular, visual representations frequently incorporate various components, such as discipline-specific graphical and diagrammatic features, varied levels of abstraction, and spatial arrangements of visual elements to convey information. Visual literacy is achieved when an individual understands the various ways in which a discipline uses these components to represent a particular way of knowing. Owing to the complex nature of visual representations, the activities through which visual literacy is developed have high cognitive load. Cognitive load can be reduced by first helping students to become fluent with the discrete components of visual representations before asking them to simultaneously integrate these components to extract the intended meaning of a representation. We present a taxonomy for characterizing one component of visual representations-the level of abstraction-as a first step in understanding the opportunities afforded students to develop fluency. Further, we demonstrate how our taxonomy can be used to analyze course assessments and spur discussions regarding the extent to which the development of visual literacy skills is supported by instruction within an undergraduate biochemistry curriculum

Hints of a Fundamental Misconception in Cosmology

To explore the frequency and range of student ideas regarding the Big Bang, nearly 1,000 students from middle school, secondary school, and college were surveyed and asked if they had heard of the Big Bang and, if so, to describe it. In analyzing their responses, we uncovered an unexpected result that more than half of the students who stated that they had heard of the Big Bang also provided responses that suggest they believe that the Big Bang was a phenomenon that organized pre-existing matter. To further examine this result, a second group of college students was asked specifically to describe what existed or occurred before, during, and after the Big Bang. Nearly 70% gave responses clearly stating that matter existed prior to the Big Bang. These results are interpreted as strongly suggesting that most students are answering these questions by employing an internally consistent element of knowledge or reasoning (often referred to as a phenomenological primitive, or p-prim), consistent with the idea that “you can’t make something from nothing.” These results inform the debate about the extent to which college students have pre-existing notions that are poised to interfere with instructional efforts about contemporary physics and astronomy topics

Comparison of Views of the Nature of Science between Natural Science and Nonscience Majors

Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited. In this study, NOS views of undergraduates in introductory environmental science and upper-level animal behavior courses were measured using Likert items and open-ended prompts. Analysis revealed similarities in students' views between the two courses; both populations held a mix of naïve, transitional, and moderately informed views. Comparison of pre- and postcourse mean scores revealed significant changes in NOS views only in select aspects of NOS. Student scores on sections addressing six aspects of NOS were significantly different in most cases, showing notably uninformed views of the distinctions between scientific theories and laws. Evidence-based insight into student NOS views can aid in reforming undergraduate science courses and will add to faculty and researcher understanding of the impressions of science held by undergraduates, helping educators improve scientific literacy in future scientists and diverse college graduates

Investigation of a Stand-Alone Online Learning Module for Cellular Respiration Instruction

With the recent rise of alternative instructional methodologies such as flipped classrooms and active learning, many core concepts are being introduced outside of the classroom prior to scheduled class meeting times. One popular means for external concept introduction in many undergraduate biology courses is the use of stand-alone online learning modules. Using a group of four large introductory biology course sections, we investigate the use of a stand-alone online learning module developed using animations from Virtual Cell Animation Collection as a resource for the introduction of cellular respiration concepts outside of the classroom. Results from four sections of introductory biology ( = 629) randomized to treatments show that students who interacted with the stand-alone online learning module had significantly higher normalized gain scores on a cellular respiration assessment than students who only attended a traditional lecture as a means of concept introduction ( < 0.001, = 0.59). These findings suggest a superior ability to convey certain introductory cellular respiration topics in a stand-alone manner outside of the classroom than in a more traditional lecture-based classroom setting

Development of a Certification Exam to Assess Undergraduate Students\u27 Proficiency in Biochemistry and Molecular Biology Core Concepts

With support from the American Society for Biochemistry and Molecular Biology (ASBMB), a community of biochemistry and molecular biology (BMB) scientist-educators has developed and administered an assessment instrument designed to evaluate student competence across four core concept and skill areas fundamental to BMB. The four areas encompass energy and metabolism; information storage and transfer; macromolecular structure, function, and assembly; and skills including analytical and quantitative reasoning. First offered in 2014, the exam has now been administered to nearly 4000 students in ASBMB-accredited programs at more than 70 colleges and universities. Here, we describe the development and continued maturation of the exam program, including the organic role of faculty volunteers as drivers and stewards of all facets: content and format selection, question development, and scoring
