His concepts are seen as abstract and difficult to understand and can be contextualized through experimentation. Experimentation is used in the classroom to allow students to view the applicability of the contents through observation, creating hypotheses, discussion and conclusions. OBJECTIVES: The aim of this study was to evaluate the presence of experimentation in biochemistry content  in high school books. MATERIALS AND METHODS: In this way, it was analyzed the presence of experimental activities in the textbooks approved by the National Textbook Plan 2015 \"Biology 1\", authored by Cesar da Silva Junior, Sezar Sasson and Nelson Caldini Junior, and in the book \" Chemistry - Volume 3 \"by Martha Reis. RESULTS: At the end of the unit where the biochemical concepts are covered in the book \"Biology 1\" is presented an interdisciplinary project called \"Enzymes - chemical tools of life\" that proposes four experiments on catalase, pH and contact surface enzyme-substrate. They are easy activities to be implemented with affordable materials. Already at the Chemistry book, when addressing the biochemistry there is only one proposal for experimental activity called \"Glycolic Extract of milk proteins\". In this case, we need materials like food processor and enameled pots, which can hinder your performance in virtual classes, however, the experiment is easy to perform. Both books contain questions after the experimental proposals enhancing the questioning of the activities and understanding the contents addressed. CONCLUSIONS: The present experimental activities in the textbooks are mostly easy to apply and is not required sophisticated equipment of Sciences laboratories.

In order to motivate biology undergraduates for contents of central energetic metabolism, we addressed the Krebs cycle structure and functions to an evolutionary view. To this end, we created a study guide which contextualizes the emergence of the cyclic pathway, in light of the prokaryotic influence since early Earth anaerobic condition to oxygen rise in atmosphere. OBJECTIVES: The main goal is to highlight the educational potential of the material whose subject is scarcely covered in biochemistry textbooks. MATERIALS AND METHODS: The study guide is composed by three interrelated sections, the problem (Section 1), designed to arouse curiosity, inform and motivate students; an introductory text (Section 2) about life evolution, including early micro-organisms and Krebs cycle emergence, and questions (Section 3) for debate. The activity consisted on a peer discussion session, with instructors tutoring. The questions were designed to foster exchange of ideas in an ever-increasing level of complexity, and cover subjects from early atmospheric conditions to organization of the metabolism along the subsequent geological ages. RESULTS AND DISCUSSION: We noticed that students were engaged and motivated by the task, especially during group discussion. Based on students’ feedbacks and class observations, we learned that the material raised curiosity and stimulated discussion among peers. It brought a historical and purposeful way of dealing with difficult biochemical concepts. CONCLUSIONS: The whole experience suggests that the study guide was a stimulus for broadening comprehension of the Krebs cycle, reinforcing the evolutionary stance as an important theme for biology and biochemistry understanding. On the other hand, we do not underestimate the fact that approaching Krebs cycle from an evolutionary standpoint is a quite complex discussion for the majority of students. KEYWORDS: Evolution.

Gagianone, M. Ribeiro","doi":"10.16923/REB.V13I2.574","DOIUrl":"https://doi.org/10.16923/REB.V13I2.574","url":null,"abstract":"Introduction The X-linked adrenoleukodystrophy (X-ALD) is characterized by mutations in very long chain fatty acids (VLCFA) peroxisome transporter, leading to VLCFA accumulation in myelin sheath. In the 70’s and 80’s it was hypothesized that X-ALD is caused by enzymatic deficits in FA-coenzyme A connection, VLCFA degradation or FA elongation. The latter enabled Lorenzo’s oil (LO) treatment, which became famous by the homonym movie. The apparent initial therapy effectiveness lead to LO administration in many patients, although with biochemical knowledge progress its relevance has been questioned. Objectives Our aim was to discuss X-ALD researches in “Lipids Metabolism” classes during 2014 Biochemistry courses to Biology and Biomedicine undergraduate students at Fluminense Federal University to illustrate how scientific knowledge is constructed. Materials and Methods In order to contrast the recent scientific advances with the information spread to society through “Lorenzo’s Oil”, the movie in edited version was presented to students followed by a questionnaire with Likert scale to evaluate the perception of scientific knowledge exposed by the movie. Afterwards, a Guided Study containing a brief history and discursive questions based upon a paper (Wiesingner et.al, J. Biol. Chem. 288:19269, 2013) was applied in class. Results and Discussion From 58 students who filled in the questionnaire,72,4% considered the movie shows that X-ALD biochemical knowledge has been achieved. This notion was confirmed since 84,5% agreed LO is an effective alternative treatment if X-ALD is early detected. The same percentage agreed that based on the movie the biochemical deficiency relies on an enzyme involved in VLCFA degradation. Although the movie transmits the idea that the cure has been found, 67,2% believed X-ALD biochemical mechanisms are not fully comprehended. Conclusions The Guided Study/movie application was very effective because allowed the understanding of mechanisms completely unknown by the time of LO development and also the comprehension of scientific knowledge construction through a playful and participative activity.

The selected topics were, amino acids and proteins, enzymes, cellular respiration, glycogen metabolism, gluconeogenesis, lipid metabolism, metabolic integration, dyslipidemia and atherogenesis, pathophysiology of diabetes mellitus and metabolic syndrome, mechanisms of diabetes mellitus complications. The hobby activities chosen were direct, duplex, self-defined, cryptogram, bugs game. Both issues such as the type of hobby was drawn between groups. The groups had to: elaborate hobby; presents it to class orally, applying the questions prepared; printing and expose the hobby at the wall in the University; answer an evaluation regarding the preparation of work; and all groups should get together and organize one titled magazine \"Hobby with Biochemistry\" and deliver it printed. Results and conclusions: According the groups, the greatest difficulty was the adequacy of the questions posed in the required format, once they had only one issue and restricted space for the responses. Furthermore, the formatting was also identified as a point very difficult in activity elaboration.

However, although most academics would agree that assessment is a critical aspect of their roles as teachers it is often an aspect of teaching that is regarded more as an additional task rather than an integral component of the teaching/learning continuum. An additional impediment to high quality assessment is the non-evidence based-approach to the decision making process. The overall aim of this project was to improve the quality of assessment in Biochemistry and Molecular Biology undergraduate education by promoting high quality assessment. Materials and methods To do this we developed and trialled an audit tool for mapping assessment practices. The audit tool was designed to gather data on current assessment practices and identify areas of good practice in which assessment aligned with the learning objectives and areas in need of improvement. This evidence base will then be used to drive change in assessment. Results and conclusions Using the assessment mapping tool we have mapped the assessment regime in a Biochemistry and Molecular Biology major at Monash University. Criteria used included: assessment type, format, timing, assessors, provision of feedback, level of learning (Bloom’s), approaches taken to planning assessment. We have mapped assessment of content and the systematic development of higher order learning and skills progression throughout the program of study. The data has enabled us to examine the assessment at unit (course) level as well as the vertical development across the major.
