Animation model to conceptualize ATP generation: a mitochondrial oxidative phosphorylation

Abstract

Adenosine triphosphate (ATP) is the molecular unit of intracellular energy and it is the product of oxidative phosphorylation of cellular respiration uses in cellular processes. The study explores the growth of the misconception levels amongst the learners and evaluates the effectiveness of animation model over traditional methods. The data obtained from the sixty B.Sc. students found the growing misconception status in the mitochondrial oxidative phosphorylation test. Euclidean Distance Formula was used to analyzing and interpreting the various growing misconception levels among the students and found that 88% of students have different types of misconception those were rooted in preconception derived from everyday experiences of students. Similarly, Chi-Square test used to observe the effects of the animation model over the "correct" and "misconception" status of the students and it was resulted that misconception levels relatively decreased from 88% to 15%, and only 15% of students have the misconception problems. However, Univariate Analysis of Variance used to measure the effectiveness of animation model of mitochondrial oxidative phosphorylation over the control group. It results that F(1/ 118) 323.42 P < 0.01) was significant and there existed significant difference in between control and experimental group achievement of ATP generation of mitochondrial oxidative phosphorylation.

Development of an Online Three-Tier Diagnostic Test to Assess Pre-University Students’ Understanding of Cellular Respiration

“…The students ISSN 1648-3898 that chose the incorrect reason A may only have basic knowledge of chemiosmosis as a process to produce ATP; they did not understand the theory behind chemiosmosis and were not able to explain the concept of how energy is transferred or transformed in the production of ATP by chemiosmosis. This result is in line with research conducted by Jena (2014) who found that the growing misconception status of learners in ATP generation from mitochondrial oxidative phosphorylation is high.…”

“…According to researchers in this area (for e.g. Bajd, Praprotnik and Matyasek, 2010;Jena, 2014) cellular respiration topic is very difficult to understand.…”

Multimedia-aided instruction in teaching basic life support to undergraduate nursing students

“…Multimedia and its components. As misconceptions and difficulties among college students abound regarding cardiorespiratory physiology, and oxidative phosphorylation and ATP generation by mitochondria (10,16,18), together with an inability to integrate relevant science knowledge (7,14), a multimedia instruction package for undergraduate nursing students was developed. The multimedia package was created with a focus on correcting the misconceptions and reducing the barrier to attain basic science knowledge required for proper understanding of BLS.…”

“…A recent study involving healthcare providers in the U.S. reported students are unable to answer questions on basic human physiology and on reasons for performing chest compression (7). A clear comprehension on oxidative phosphorylation and adenosine triphosphate (ATP) generation by mitochondria prove difficult according to a study of undergraduate students at a university in India (10).…”
