Assessment of learners in the anatomical sciences is a complex task as it not only tests students' fact knowledge, but also the analysis of visual information. Sometimes, novice histology learners must acquire image recognition skills of microscopic structures in a short time frame. This paper describes a strategy of offering first year dental students at the University of Michigan a short, non-grade contributing, formative assessment quiz in order to better prepare them for a high-stakes, final summative histology examination.

Traditional academic lectures have long been criticized as providing a passive learning environment to students. Often, they do not capture the audience's attention, resulting in learners being distracted or bored and thereby reducing their learning efficacy. Consequently, they are being abandoned by many schools and universities as an educational modus or modified into more learner-centered experiences.

Histology or microanatomy is the science of the structure and function of tissues and organs in metazoic organisms at the cellular level. By definition, histology is dependent on a variety of microscope techniques, usually light or more recently virtual, as well as electron microscopy. Since its inception more than two centuries ago, histology has been an integral component of biomedical education, specifically for medical, dental, and veterinary students.

For the last two centuries, the scholarly education of histology and pathology has been based on technology, initially on the availability of low-cost, high-quality light microscopes, and more recently on the introduction of computers and e-learning approaches to biomedical education. Consequently, virtual microscopy (VM) is replacing glass slides and the traditional light microscope as the main instruments of instruction in histology and pathology laboratories. However, as with most educational changes, there are advantages and disadvantages associated with a new technology.

Over the past decades, biomedical education has changed considerably, mostly by the introduction of novel didactic strategies, as well as the addition of technology. As a consequence, the centuries-old lecture-style presentation has come under criticism for providing only a one-directional transfer of information. However, the delivery of traditional lectures has also seen considerable changes such as the use of Microsoft PowerPoint slides which can be projected and serve as lecture handouts to learners.

With anatomical education becoming a global endeavor, free online resources offered via the Internet or other electronic venues are of increasing importance for teaching and learning communities worldwide. Students and instructors from developing countries, often limited in access to modern instructional resources by infrastructural and financial constraints, are frequent users of such online learning tools. During the recent Covid-19 pandemic when all academic institutions were forced to quickly switch to a non-contact mode of teaching, free online instructional resources were often essential for continuing the educational mission.

The term "histology" was coined a little over 200 years ago and the subject has always relied on microscopy as its defining technology. Microscopy was and still is an essential approach for the description of cellular components and their arrangements in living organisms. For more than a century and a half, histology or microanatomy has also been part of the basic science education for biomedical students.

Introduction: New technologies like virtual microscopy have revolutionized histology education. However, first-year students often require additional assistance with virtual slides. Online self-directed learning modules (SDLMs) were developed to provide such support to learners by offering them short instructional videos that are uploaded to YouTube and the instructional website.

E-learning strategies have become an important part of biomedical education. However, why and how medical students select hardware tools and software formats during their preclinical education has not been sufficiently evaluated. These aspects should be considered when designing or offering new e-learning modalities to learners.

The availability of social media in biomedical education is rapidly expanding. However, there is little information comparing the utility of different social media platforms. The authors sought to describe and evaluate a student-led medical education tool, ObGyn Delivered, that uses three social media platforms (Facebook, Instagram, and Twitter) in order to understand each platform's potential roles, benefits, and barriers and describe their advantages and limitations.

In an ever-changing medical curricular environment, time dedicated for anatomical education has been progressively reduced. This happened at the University of Michigan Medical School starting in 2016-2017 when preclinical medical education was condensed to one year. Histology instruction remained integrated in organ system courses but reduced to a lecture-only format without scheduling time for laboratory exercises, requiring students to study virtual histology slides on their own time.

Background: Using revised Bloom's taxonomy, some medical educators assume they can write multiple choice questions (MCQs) that specifically assess higher (analyze, apply) versus lower-order (recall) learning. The purpose of this study was to determine whether three key stakeholder groups (students, faculty, and education assessment experts) assign MCQs the same higher- or lower-order level.

Methods: In Phase 1, stakeholders' groups assigned 90 MCQs to Bloom's levels.

Electronic learning resources are popular with today's students. However, how students choose their favorite e-learning resources is not well-understood. The popular histology self-review tool was offered in three different interfaces to students participating in two histology courses (Cell and Developmental Biology [CDB] 450/550 and DENT 510).

The scientific endeavor has many facets, extending well beyond the experimental research bench. However, in most fields, especially in the biomedical sciences, the traditional career pathway for scientists is first joining and later leading an experimental research laboratory or program. As a result, scientific education is often focused on training new bench researchers.

Introduction: Histology teaching in India and in other developing countries has not changed much over the past decades and has not joined the global movement of using virtual microscopy (VM). Many factors may have contributed to this academic inertia-including curricular requirements for traditional microscopy (TM) skills, assessments that are heavily based on TM, and unfamiliarity with modern technology among faculty, as well as infrastructural shortcomings. This study is aimed at overcoming these roadblocks by using a blended approach combining VM with TM in a tradition-centered curricular setting.

When educators develop and introduce new learning approaches or resources, they usually have specific didactic goals in mind that they want to achieve. However, these goals may not always match the needs of their students, who often confound such plans by finding new and different uses for the educational tools that are offered to them. Originating from the author's work as the histology component director at the University of Michigan, the experience described here provides an example of a learning resource being reappropriated by the learning community.

Over the last 20 years, virtual microscopy has become the predominant modus of teaching the structural organization of cells, tissues, and organs, replacing the use of optical microscopes and glass slides in a traditional histology or pathology laboratory setting. Although virtual microscopy image files can easily be duplicated, creating them requires not only quality histological glass slides but also an expensive whole slide microscopic scanner and massive data storage devices. These resources are not available to all educators and researchers, especially at new institutions in developing countries.

New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi-year study of the first-year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated.

Bloom's taxonomy was adopted to create a subject-specific scoring tool for histology multiple-choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher- and student-generated quiz and examination questions from a graduate level histology course. Multiple-choice questions using histological images were generally assigned a higher BTHT level than simple text questions.
