A core syllabus for histology within the medical curriculum-The cell and basic tissues

Transforming histology students from passive lecture listeners into active lecture learners

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. This descriptive article outlines a strategy of inserting active learning PowerPoint slides into traditional histology lectures. Suggestions and advice for adding or improving existing active learning slides are being offered to readers, who are planning to modify their own lecture presentations. The author's experience of using this formative assessment strategy with different types of histology learners is also discussed.

A core syllabus for histology within the medical curriculum - The cardiovascular and lymphoid systems, the respiratory and digestive systems, and the integument

Medical courses worldwide are undergoing significant curricular changes, including the teaching and learning of histology. In order to set international standards for the anatomical sciences, the International Federation of Associations of Anatomists (IFAA) is developing core anatomical syllabuses by means of Delphi panels. Already published is a core syllabus for the teaching of the cell and the basic tissues within medicine. Here, we record the deliberations of an IFAA Delphi panel commissioned to develop core subject matter for the teaching within a medical histology course of the cardiovascular and lymphatic circulatory system, the lymphoid, respiratory, and digestive systems, and the integument. The Delphi panel was comprised of academics from multiple countries who were required to review relevant histological topics/items by evaluating each topic as being either "Essential," "Important," "Acceptable," or "Not required." Topics that were rated by over 60% of the panelists as being "Essential" are reported in this paper as being core topics for the teaching of medical histology. Also reported are topics that, while not reaching the threshold for being designated as core material, may be recommended or not required within the curriculum.

Histology as a paradigm for a science-based learning experience: Visits by histology education spirits of past, present, and future

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. Traditionally, it has been taught in two major components, a didactic transfer of information, either in a lecture or self-learning format, and in active-learning laboratory sessions. These two modes of histology instruction conform with the dual-processing theory of learning, one being more automatic and depending mainly on rote memorization, whereas the other is analytical, requiring more advanced reasoning skills. However, these two components of histology education are not separate and independent, but rather complementary and part of a multi-step learning process that encourages a scientific analysis of visual information and involves higher-level learning skills. Conventional, as well as modern electronic instruction methods (e-learning) have been used in complementary ways to support the integrated succession of individual learning steps as outlined in this manuscript. However, as recent curricular reforms have curtailed instructional time, this traditional format of teaching histology is no longer sustainable and a reflective reassessment of the role of histology in modern biomedical education is a timely necessity.

Identification of histological threshold concepts in health sciences curricula: Students' perception

Students' metacognitive skills and perceptions are considered important variables for high-quality learning. In this study, students' perceptions were used to identify histological threshold concepts (integrative, irreversible, transformative, and troublesome) in three health sciences curricula. A specific questionnaire was developed and validated to characterize students' perceptions of histological threshold concepts. A sample of 410 undergraduate students enrolled in the dentistry, medicine, and pharmacy degree programs participated in the study. Concepts assessed in the study were clustered to ten categories (factors) by exploratory and confirmatory factor analysis. Concepts linked to tissue organization and tissue functional states received the highest scores from students in all degree programs, suggesting that the process of learning histology requires the integration of both static concepts related to the constituent elements of tissues and dynamic concepts such as stem cells as a tissue renewal substrate, or the euplasic, proplasic and retroplasic states of tissues. The complexity of integrating static and dynamic concepts may pose a challenging barrier to the comprehension of histology. In addition, several differences were detected among the students in different degree programs. Dentistry students more often perceived morphostructural concepts as threshold concepts, whereas medical students highlighted concepts related to two-dimensional microscopic identification. Lastly, pharmacy students identified concepts related to tissue general activity as critical for the comprehension and learning of histology. The identification of threshold concepts through students' perceptions is potentially useful to improve the teaching and learning process in health sciences curricula.

Teaching Cellular Architecture: The Global Status of Histology Education

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. Traditionally, histology has been taught in two sequential phases, first a didactic transfer of information to learners and secondly a laboratory segment in which students develop the skill of analyzing micrographic images. In this chapter, the authors provide an overview of how histology is currently taught in different global regions. This overview also outlines which educational strategies and technologies are used, and how the local and cultural environment influences the histology education of medical and other students in different countries and continents. Also discussed are current trends that change the teaching of this basic science subject.

Past and Current Learning and Teaching Resources and Platforms

For over two centuries, the educational landscape both nationally and globally has changed tremendously. The more traditional teaching and learning resources and platforms, such as traditional textbooks, chalkboards and whiteboards, overhead transparency and carousel projectors, and traditional classroom settings, have been either replaced or supplemented in the anatomical sciences by integrated and virtual eBooks, online learning management (OLM) platforms, and virtual learning and meeting apps. Virtual teaching and learning, especially proliferated with the advent and aftermath of the COVID-19 pandemic, and institutions worldwide that had already been utilizing virtual class and lab sessions in their anatomy curricula expanded virtual course offerings. Many institutions have retained virtual course offerings even after the pandemic, given the distance learning benefits. The future of anatomy education holds many promising possibilities given the voracious speed with which technology is advancing. One such promising advancement is the full, seamless incorporation of virtual three-dimensional (3D) immersive and semi-immersive learning into anatomy laboratories and classroom settings globally as well as into students' laptops and handheld devices for easy use at home or anywhere.

Histology education in an integrated, time-restricted medical curriculum: Academic outcomes and students' study adaptations

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. In accordance with the shortened instructional time, the number of histology examination questions was reduced more than twofold. This study analyzed students' histology examination results and assessed their motivation to learn histology and use of educational opportunities before and after these curricular changes were implemented. Students' motivation to learn histology and their evaluation of histology lectures increased in the new curriculum. However, students devoted less study time to studying histology. Students' cumulative histology examination scores were significantly lower in the new curriculum and the number of students with overall scores <75%, defined as a substandard performance, increased more than 15-fold. Academically weaker students' histology scores were disproportionately more affected. As medical educational strategies, priorities, and curricular frameworks continue to evolve, traditional didactic topics like histology will need to adapt to continue providing educational value to future health care providers.
