It revealed the vulnerability of education systems to external changes and risks and challenged institutions and educators to transform and adapt at short notice. Following the COVID-19 outbreak, one of the natural consequences was the unprecedented rise in online education. The transition from the in-person teaching format to e-learning exposed teachers and students to significant challenges. In the biomedical field, e-learning forced teachers to rethink hands-on wet lab teaching into a hands-off virtual one; this digital transformation has continued in the post-pandemic period and has resulted in the emergence of hybrid models trying to harmonize the benefits of e-learning with those of in-person teaching. In this narrative review, we analyzed articles published between 2020 and 2024 focusing on the teaching of molecular and cellular biology laboratory through online or blended learning formats. We focused on the impact that pedagogical innovation in laboratory e-learning has had on student perceptions, experience, and outcomes. We have extracted five major themes that should be considered by educators involved in course design to enhance the benefits of exposing students to learning in a virtual lab: (1) the varying effectiveness of laboratory e-learning, (2) the potential for online labs to foster self-efficacy and confidence, (3) the reduced opportunities for social interaction in virtual settings, (4) students' perspectives on virtual, blended, and in-person lab work, and (5) the importance of addressing student inequities in digital access.</p>","PeriodicalId":8830,"journal":{"name":"Biochemistry and Molecular Biology Education","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to develop a 2D Mobile-Based Virtual Laboratory Simulation (2D-MViLS) for blood glucose level measurement and evaluate its impact on pharmacy students' learning experience. In stage 1, storyboards were developed and expanded to show the overall flow and simulation in interactive 2D form using Unity for Android devices. In stage 2, usability testing was carried out. In Stage 3, reflective essays from first-year pharmacy students were analyzed using both qualitative and quantitative methods. Three key themes were identified: students' feelings, their understanding of the learning outcomes, and their reflections on the need to enhance their current knowledge and skills. Thematic analysis revealed a positive shift in students' feelings after using the 2D-MViLS. Quantitatively, 44% of students demonstrated a highly positive change, moving from pessimistic to optimistic feelings, 17% showed moderate positive change, and 51% expressed optimism before and after the simulation. Quiz marks were consistently high across all groups, with minimal variation regardless of the number of learning outcomes mentioned. Additionally, 73.9% of students identified areas for knowledge and/or skill enhancement, highlighting their engagement with the simulation. In conclusion, students' reflections reveal the positive impact of 2D-MViLS on their learning experience, indicating that implementing mobile-based virtual laboratories could significantly enhance the learning experience in biochemistry education and potentially lead to improved teaching methods in pharmacy and related disciplines.</p>","PeriodicalId":8830,"journal":{"name":"Biochemistry and Molecular Biology Education","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that one source of this perceived mismatch is that biology and chemistry textbooks use different visual representations of bond breaking and formation. We analyzed figures of ATP hydrolysis from 12 college-level introductory biology textbooks and coded each figure for its representation of energy, bond formation, and bond breaking. For comparison, we analyzed figures from six college-level introductory chemistry textbooks. We found that the majority (70%) of biology textbook figures presented ATP hydrolysis in the form \"one reactant → multiple products\" and \"more bonds in reactants → fewer bonds in products\". In contrast, chemistry textbook figures of the form \"one reactant → multiple products\" and \"more bonds → fewer bonds\" were predominantly endothermic reactions, which directly contradicts the exothermic nature of ATP hydrolysis. We hypothesize that these visual inconsistencies may be a contributing factor to student struggles in constructing a coherent mental model of energy and bonding.</p>","PeriodicalId":8830,"journal":{"name":"Biochemistry and Molecular Biology Education","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143647066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory-based instruction enhances engagement with the subject while fostering the development of practical competencies and deepening comprehension of theoretical concepts. However, constraints on time and financial resources limit the feasibility of conducting extended laboratory sessions that incorporate cutting-edge genetic techniques. This study evaluated a hybrid teaching method that combined face-to-face (F-2-F) laboratory sessions with an online simulation to instruct undergraduates on gene editing and DNA sequencing. A Unity-based simulation was developed to complement traditional F-2-F laboratory sessions, allowing students to practice DNA sequencing techniques in a low-stakes environment. The simulation was integrated into a course-based undergraduate research experience (CURE) focused on CRISPR/Cas9 gene editing in yeast. Student performance, engagement, and perceptions were assessed through laboratory assignments, access logs, and surveys. Students who engaged with the simulation prior to F-2-F sessions and those who engaged with the simulation over multiple days performed significantly better in assessments. Survey results indicated that most students found the simulation realistic and relevant and reported enhanced learning of DNA sequencing principles. Student confidence in DNA sequencing knowledge increased significantly after using the simulation. Student feedback highlighted benefits such as improved procedural understanding, stress reduction, and increased preparedness for F-2-F sessions. This approach addresses logistical challenges of traditional laboratory education while providing students with authentic, repeatable experiences in complex techniques. Our findings demonstrate the potential of integrating simulations with F-2-F instruction to enhance undergraduate education in genetics and molecular biology.</p>","PeriodicalId":8830,"journal":{"name":"Biochemistry and Molecular Biology Education","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143633373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide five detailed Nanome exercises that address a variety of key learning objectives in biochemistry and molecular biology including reviewing protein structure (secondary, tertiary, and quaternary), properties of active sites, chirality of amino acids, and ligand-enzyme interactions. The exercises we designed include built-in assessment to monitor student learning in Nanome. In addition, we supply instructor resources for starting with Nanome and implementing the exercises. After the VR exercises, we used surveys to assess student impressions. All students reported that the activities were somewhat or very helpful in learning about molecular structure.

This study involved 150 first-year medical students divided into 25 small groups of 6 each. Participants were assessed before and after engaging with the game through a structured formative assessment, a validated questionnaire measuring engagement and learning effectiveness, and a confidence level questionnaire. In-depth small-group interviews were also conducted for qualitative feedback and thematic analysis was performed. Statistical analyses were performed using SPSS version 17. The introduction of \"Pancreata-The Keto Struggle\" resulted in significant improvements in students' formative assessment scores, from a mean of 19.2 ± 1.9 before the game to 39.3 ± 2.2 out of 50 after the game (p < 0.0001). Notably, students demonstrated the highest confidence gains in managing DKA and interpreting laboratory results. Qualitative analysis identified seven common themes reflecting the game's impact on learning: collaboration, retention of concepts, internal drive, self and peer assessment, joyful learning, beyond books, and aesthetic content. Over 95% of students reported increased engagement and learning effectiveness due to the game's intrinsic motivation, narrative, and group learning mechanics. \"Pancreata-The Keto Struggle\" effectively revitalizes collaborative learning in medical education by integrating game-based learning with traditional teaching methods.
