Competency-based physiology and biochemistry education can benefit from the creative integration of imaginative narratives into traditional teaching methods. This paper proposes an innovative model using a pen and palm analogy to visualize enzyme function theories. The pen (substrate) must fit snugly into the palm (enzyme's active site) for catalysis to occur, akin to induced-fit theory. Pressing the pen's top button with the thumb represents the strain needed to convert substrate (pen with nib inside) into product (pen with nub out, ready to write). By leveraging everyday objects creatively, students can enhance their understanding and engagement with enzymatic reactions.

The emergence of ChatGPT as one of the most advanced chatbots and its ability to generate diverse data has given room for numerous discussions worldwide regarding its utility, particularly in advancing medical education and research. This study seeks to assess the performance of ChatGPT in medical biochemistry to evaluate its potential as an effective self-learning tool for medical students. This evaluation was carried out using the university examination question papers of both parts 1 and 2 of medical biochemistry which comprised theory and multiple choice questions (MCQs) accounting for a total of 100 in each part. The questions were used to interact with ChatGPT, and three raters independently reviewed and scored the answers to prevent bias in scoring. We conducted the inter-item correlation matrix and the interclass correlation between raters 1, 2, and 3. For MCQs, symmetric measures in the form of kappa value (a measure of agreement) were performed between raters 1, 2, and 3. ChatGPT generated relevant and appropriate answers to all questions along with explanations for MCQs. ChatGPT has "passed" the medical biochemistry university examination with an average score of 117 out of 200 (58%) in both papers. In Paper 1, ChatGPT has secured 60 ± 2.29 and 57 ± 4.36 in Paper 2. The kappa value for all the cross-analysis of Rater 1, Rater 2, and Rater 3 scores in MCQ was 1.000. The evaluation of ChatGPT as a self-learning tool in medical biochemistry has yielded important insights. While it is encouraging that ChatGPT has demonstrated proficiency in this area, the overall score of 58% indicates that there is work to be done. To unlock its full potential as a self-learning tool, ChatGPT must focus on generating not only accurate but also comprehensive and contextually relevant content.

This paper describes a teaching experiment in a Numerical Methods course for Master of Science students. The experiment uses scientific papers to develop modelling studies in the context of wine fermentation microbial interactions. The course involves theoretical and laboratory classes that focus on implementing numerical methods using Matlab for Initial Value Problems and Boundary Value Problems. The students are asked to formalise the mathematical model and build their own experiments using the information provided in the papers. Additionally, a parameter estimation experiment is organised, which involves generating synthetic data and computing noisy data to estimate the natural death rate of sensitive yeast. The results show that data noise significantly affects the parameter estimate and that scaling the data can help reduce the impact of measurement errors. The presented results can be used to investigate other possible assignments, such as how the evaluation of the Jacobian affects the estimation performance and compare different optimisation algorithms.

The authors, a chemistry professor and a librarian, used a qualitative survey to assess student perceptions of a Wikipedia editing assignment that they included in a large upper-level biochemistry course. The assignment was initially intended as a public-facing alternative to a short research paper, emphasizing information literacy and scientific literacy. The goal of the survey was to use the results to enhance the assignment. The results of the survey and research for the literature review inspired a novel approach to the assignment using the perspective of metaliteracy. This approach encourages students to think critically about their role as scholars in a participatory environment.

Teaching chemistry and biology students about biologics design remains challenging despite its increasing importance in pharmaceutical development. Monoclonal antibodies, commonly called mAbs, are the most popular biologics. They have been developed into drugs to treat various diseases in the past decades. Multiple challenges exist for designing proper formulations to stabilize mAbs, such as preventing aggregation and mitigating viscosity. Molecular modeling and simulations can improve pharmaceutical products by examining the interactions between mAbs and other compounds, such as excipients. To introduce students to biopharmaceuticals, eight students at the Stevens Institute of Technology participated in a semester-long course to learn the challenges of pharmaceutical development and different computational skills to study biologics design. The students started with a limited background in this field. Throughout one semester, they were introduced to various literature and software tools for modeling antibodies and studying their interactions with excipients. This paper aims to develop a course structure to be replicated at other universities and institutions to teach biopharmaceutical development to students.

Providing hands-on practical education without access to laboratories during the COVID-19 pandemic has required creativity and innovation. In this paper, co-authored by academic staff and students, we describe an at-home mobile phone-based 'spectrophotometer' experiment used in an introductory undergraduate biology course. Using colour picker apps, a smartphone can be used to quantify concentration, which was used to compare the strengths of different brands of tea. The protocol is designed to be low-cost and safe to perform outside of a laboratory. Students used the methods to learn important biochemical methods such as preparing dilutions, constructing calibration curves, normalising data and testing a hypothesis. We reflect on the experience of developing and using the protocol from a staff and student perspective, which highlights the advantages of this approach in terms of student independence and inclusivity. We also suggest alternative experiments that could be performed using the protocol. We encourage biology educators to think creatively about the possibilities for using mobile phones or at-home experiments in their teaching. Our experience suggests that at-home experiments like this protocol will have value even after the pandemic is over, particularly in terms of inclusivity.

The COVID-19 pandemic has forced a shift in thinking regarding the safe delivery of wet laboratory courses. While we were fortunate to have the capacity to continue delivering wet laboratory experiments with physical distancing and other measures in place, modifications to the mechanisms of delivery within courses were necessary to minimize risk to students and teaching staff. One such modification was introduced in BCH370H, an introductory biochemistry laboratory course, where a OneNote Class Notebook (ONCN) was used as an electronic laboratory notebook (ELN) in place of the traditional hardbound paper laboratory notebook (PLN) used prior to the pandemic. The initial reasoning for switching to an ELN was around safety - allowing course staff and students to maintain physical distancing whenever possible and eliminating the need for teaching assistants to handle student notebooks; however, the benefits of the ONCN proved to be significantly more. OneNote acted not only as a place for students to record notes but the Class Notebook's unique features allowed easy integration of other important aspects of the course, including delivery of laboratory manuals, posting of student results, notetaking feedback, sharing of instructional materials with teaching assistants, and more. Student and teacher experiences with the ONCN as used within a fully in person biochemistry laboratory course, as well as learned best practices, are reviewed.

An integrated and projected-based laboratory course was described, integrating interconnected knowledge points and biochemistry and molecular biology techniques on a research project-based system. The program, which served as an essential extension of theoretical courses to practice, was conducted with a sophomore of basic medical science who had completed the course in medical biochemistry and molecular biology. This course engaged students in learning "genetic manipulation" and "recombinant DNA technology" to understand the target gene's role in disease mechanics, thus altering evaluation and treatment for clinical disease. Students could master applied and advanced techniques, such as cell culture, transfection, inducing exogenous fusion protein expression, purifying protein and its concentration assay, quantitative polymerase chain reaction, and western bot analysis. This laboratory exercise links laboratory practices with the methods of current basic research. Students need to complete the experimental design report and laboratory report, which could be advantageous for improving their ability to write lab summaries and scientific papers in the future. The reliability and validity analyses were conducted on the questionnaire, and we examined students' satisfaction with the course and their gains from the course. The student feedback was generally positive, indicating that the exercise helped consolidate theoretical knowledge, increase scientific research enthusiasm, and provide a powerful tool to be a better person and make informed decisions.

Adult learning involves the analysis and synthesis of knowledge to become competent, which cannot be assessed only by traditional assessment tool and didactic learning methods. Stimulation of higher domains of cognitive learning needs to be inculcated to reach a better understanding of the subject rather than traditional assessment tools that relies primarily on rote learning. So, there is need for an alternative assessment tool. Hence, we conducted a study where we used case-based examination methodology. This study was conducted on 226 1st year MBBS students in Maulana Azad Medical College, New Delhi (India). Based on their compiled internal assessment marks according to monthly formative assessment, students were categorized into 3 groups (I: 0-7; II: 8-14; III: 15-20) marks out of 20 marks respectively. Two sets of question papers were set by three examiners, on the same topics carrying 50 marks each. The first set was based on traditional assessment tool (Paper-A) with recall questions and second set on case-based assessment method (Paper-B). Out of 226 students, 146 were males and 80 were females. For all groups, marks (mean ± SD) in Paper B were found to be higher (18.40 ± 4.29, 30.01 ± 4.12, and 40.33 ± 1.15) as compared to paper A (10.88 ± 4.34, 21.96 ± 7.34, and 31.50 ± 6.94) respectively. However, we found that there was significant (p < 0.001) difference in group I & II, whereas with group III, difference was found to be insignificant. Hence, we concluded that students performed better in case-based assessment rather than traditional method due to their direct involvement. Thus, for better memory and deeper learning the subjects can be assessed by case-based assessment method.

Presently, a variety of policies and measures has implemented to enhance the scientific research and innovation ability of medical students, but in the process of practice, there are many problems, such as they lack of independent topic selection ability, weak scientific research skills, lack of autonomous learning ability, the research results are simple and ineffective, limited teacher guidance time and so on. This paper attempted to build an effective model for the promotion of medical students' scientific research and innovation ability, in order to establish an efficacy evaluation model of the "Medical students' Innovative Scientific Research Program." Undergraduates, graduate assistants, and tutors were interviewed with the Behavioral Event Interview technique, and a questionnaire of efficacy evaluation characteristics concluded from the interviews was formed. The questionnaire was conducted on medical students in the Medical students' Innovative Scientific Research Program, and the constructed model was analyzed using reliability analysis, validity analysis, and variation analysis. At the same time, the experimental teaching models are summarized and combed, and compared with other methods such as independent sample test. The results show the model could effectively evaluate the efficacy of the Medical students' Innovative Scientific Research Program and its teaching model is effective in cultivating medical students' learning and scientific research ability. It can provide theoretical support and practical reference for the evaluation and reform of the teaching modes related to the cultivation of scientific and innovative ability of medical students.

The purpose of the presented article is to evaluate the students' perception of the online teaching educational model as a part of the "Biochemistry with Elements of Chemistry" course conducted during the COVID-19 pandemic at the Faculty of Medicine of the Jagiellonian University Medical College. The first part of the article reflects upon the pandemic impact on the transition from the in-person (standard format) to a complete remote learning format. The next part is based on the responses of the students to a questionnaire and presents an analysis of the students' preferences and perceptions regarding synchronous and asynchronous teaching methods. Students answered questions about the advantages and disadvantages of distance learning programs. They indicated the most suitable learning mode in terms of gaining knowledge and enhancing their motivation to learn. They listed factors that facilitated remote learning as well as those which made it difficult and posed a challenge to adjust to the new system, in all types of classes, that is, lectures, seminars, and laboratories. The last part of this paper presents the results of the students' performance in the pandemic-enforced system and compares them with the results from the previous class of students from the past year, when teaching was conducted mainly in the standard format. The conclusions from the given analysis may enable beneficial changes for the "Biochemistry with Elements of Chemistry" course for remote teaching in the future. It may also provide valuable insights for such types of courses conducted at other Universities and promote deliberations to continuously improve learning outcomes.

This paper explores language beliefs and writing practices of an international scholar in Biochemistry working at a large U.S. research university. Although the participant articulated monolingual ideologies and a desire to become like a 'native speaker,' he did not consider advanced writing skills in English a prerequisite for publishing in English in his field. Through 'talk-around-text' (Lillis 2008) and visits to his laboratory, we examine what resources the participant deemed valuable in the process of producing a scientific article. Adopting a spatial orientation to writing (Canagarajah 2018a), we pay particular attention to the spatial repertoires that shaped his recent first-author publication. We bring out the tensions between his language ideologies and actual communicative practices and discuss the theoretical and pedagogical implications of our research. Ultimately, we argue that a spatial orientation to communication expands the notion of bilingualism by urging us to consider people's actual creative practices of meaning-making in particular spaces rather than focus on isolated cognitive abilities.

Ion channel sensors have several applications including DNA sequencing, biothreat detection, and medical applications. Ion channel sensors mimic the selective transport mechanism of cell membranes and can detect a wide range of analytes at the molecule level. Analytes are sensed through changes in signal patterns. Papers in the literature have described different methods for ion channel signal analysis. In this paper, the authors describe a series of new graphical tools for ion channel signal analysis which can be used for research and education. The paper focuses on the utility of these tools in biosensor classes. Teaching signal processing and machine learning for ion channel sensors is challenging because of the multidisciplinary content and student backgrounds which include physics, chemistry, biology, and engineering. The paper describes graphical ion channel analysis tools developed for an online simulation environment called J-DSP. The tools are integrated and assessed in a graduate bio-sensor course through computer laboratory exercises.

This paper describes the development of a fully remote upper-class biochemistry lab course. The sudden change to online teaching in the middle of spring semester 2020 had a primarily negative impact on laboratory teaching. These effects were mitigated because the students had done many of the basic hands-on procedures before the switch. A true "at-home" biochemistry lab module was implemented in the fall semester of 2020 to ensure students could have a hands-on lab experience in a remote setting despite the remaining COVID-19 restrictions placed upon universities. The module covered several fundamental concepts and techniques found in a first semester biochemistry lab sequence: extraction and purification of a protein from a sample, and further analysis of the protein. Tyrosinase was isolated and purified from a banana extract followed by kinetic analysis of the enzyme. A key component to the module is an LED light board that, in combination with a cell-phone app, made a simple at-home colorimeter. The module was implemented in three sections of a first semester biochemistry lab course (81 students total) in the fall of 2020, and components of it have been used periodically since. Some of the procedures are now being implemented into normal in-lab sessions. An assessment in terms of a student survey showed that most of the students were able to adapt to this format and felt that their learning was not impeded.

Quantitative analysis in analytical chemistry is divided into semi-,relative, and absolute analysis. An example of each analysis is pH test paper, internal standard, and standard addition, respectively. However, their definition and differences have not yet been explained to students sufficiently in classes as well as textbooks. Polymerase chain reaction (PCR) is a good demonstration of quantitative analysis because it covers all three methods of quantification listed above. For example, traditional PCR can perform semi quantification; real-time PCR includes both relative and absolute quantitation. Therefore, in this tutorial article, we take PCR as an example to explain the kinds of methods of quantification to students. The basic principle and theories of the three PCR techniques for quantification are demonstrated and derived in detail. This will help students obtain comprehensive knowledge of quantitative analysis by studying the theoretical principles of different PCR techniques and further understanding their applications by comparing the characteristics of semi-, relative, and absolute quantification. This report is an attempt to combine teaching of chemistry with biology and present theoretical principles in a new way, which will be a helpful complement to teaching theoretical concepts in analytical chemistry and biochemistry courses.

As a representative catabolic reaction that widely exists in nature, anaerobic digestion (AD) exhibits great value regarding the global carbon cycle, renewable energy development, and environmental protection. Such an important biochemical reaction was ignored before and should be introduced into the teaching and textbooks of undergraduate biochemistry courses. However, students may face obstructions when learning AD theories since the metabolic pathways in AD are very complex. To solve these problems, an instructive metabolic minimap of the AD reaction was designed, including its reaction stages, reaction pathways, substrates, and enzymes. Furthermore, the interrelationships between aerobic catabolism (AEC) and anaerobic catabolism (ANC) were also summarized by combining the catabolic pathways of typical biological macromolecules. In this paper, AD theories were first replenished into undergraduate biochemistry courses by metabolic minimap, which not only provided valuable supports for the practical teaching of AD in undergraduate biochemistry courses, but also acted as an important reference for students in biology-related majors and biochemistry teachers.

Many disciplines have used concept inventories (CI) to better understand the alternative ideas held by students. Administering a CI at both the beginning and the end of the semester can yield much information. For example, a comparison of both pre- and post-test responses can help determine if specific gains in student learning were met. In this paper, we describe the development of a concept inventory over four academic years for the one-semester general, organic, and biochemistry (GOB) course required for nursing students. Questions were designed around course topics and to identify common misconceptions, which were gathered from the literature, student interviews, and content experts. The instrument was refined over several iterations to ensure that all questions were appropriate and understandable while providing useful information. The final version demonstrated appropriate gains in the comparison of pre- and post-test results for an active learning classroom and results are discussed. In addition, item quality was ascertained via the discrimination and difficulty values, and Cronbach's alpha coefficient was computed for the entire test as a measure of its reliability.

Games can help learners of all ages retain knowledge and build skills such as critical thinking. As such, they could be a useful tool in supporting practical training at the university level. This paper describes the development, use, and evaluation of a card game based on protein purification techniques, for a large cohort of undergraduates studying Molecular Biology and related subjects. Game materials are available and can be adapted for a different audience. Players collect cards representing chromatography columns, buffers, and elution methods by drawing cards from a common deck, and discard them in order to separate a single protein from a mixture of molecules with different properties (represented by a separate set of cards). Surveys showed that the game met its three goals: to assess, increase, and apply subject knowledge; to develop skills in communication and experimental planning; and to provide a fun experience. It was more successful for those students who enjoy games and puzzles in their spare time than for those who do not, correlating with the 'gamer' group finding it easier to understand and remember the rules of the game. Thus, games can form a useful part of biochemistry teaching practice.

Oxidation number (ON) is taught as an electron-counting concept for redox reactions in chemistry curriculum. The molecular formula method, the Lewis formula method, and the structural formula method have all been used to determine ON. However, the task of assigning ON still poses problems for some teachers and students. This paper explores a new method, the fragmentation method, which is a visual approach for counting the individual ON of any atom according to its structural formula. The critical step is to break the carbon-heteroatom bond into organic fragments and inorganic fragments. The individual ON of carbon atoms and heteroatoms can be determined by the bond cleavages in the organic and biological compounds. The mean ON of carbons can be calculated by the arithmetic mean of all individual ON of carbons in a molecule or molecular ion. The step-by-step operating procedures and examples are provided. When comparing corresponding molecules in organic conversions, the change of individual ON of atoms can be used as a tool for determining the number of transferred electrons. Furthermore, a reaction site can be identified by their changes of individual ON, chemical composition, and bond order in metabolic redox reactions.

Does early exposure to information literacy promote long-term student success? This paper describes a longitudinal case study testing the hypothesis that students who engage with scientific literature and develop information literacy early in their undergraduate studies will achieve higher grades on literature-based assignments in future coursework. We reasoned that students with previous experience in the scientific literature will develop more efficient and effective strategies to search and evaluate the literature and will ultimately favor higher-quality journals. To test these hypotheses, student performance data were collected during scientific literature-based assignments in two upper-division undergraduate lecture courses, Biochemistry 1 and Biochemistry 2. Data were analyzed from two student populations: students with prior information literacy instruction and critical practice from an Honors General Chemistry course sequence, and those students who had not undergone this training. The results indicate that, in Biochemistry 1, students with this prior information literacy training tend to use more professional, expert-like tools for exploring scientific literature and earn statistically higher scores on literature-based projects. However, by Biochemistry 2, the gaps close in both the exploration of the scientific literature and grade performance. This indicates that once students develop a foundation in information literacy, their sophistication in finding information and their performance on subsequent literature-based tasks improve. There was a small and statistically insignificant tendency for groups containing more students with prior information literacy training to cite more articles from the primary literature. However, the quality of the citations, as measured by journal impact factors, did not differ between the populations. The results of this interdisciplinary case study suggest that teaching information literacy to science students has both immediate and long-lasting benefits.
