Abstract

In this work the conical Ni structures were obtained from an electrolyte containing NH4Cl as a crystal modifier. This process is called one-step method and allows to cover large areas with micro- and nanostructures during a single electrodeposition. Presence of NH4Cl promotes a vertical direction of structure growth in order to block a horizontal one. Additionally, this method does not require using chromic acid solution, which is dangerous for the environment. Due to the ferromagnetic properties of Ni, obtained coatings could be applied as magnetic devices. The influence of the parameters such as a preparation of copper substrate, a composition of electrolyte and electrodeposition conditions (time, the electrolyte temperature and current density) was investigated in this work.

Abstract

Background: The aim of the study was to determine the predominant learning style and type of intelligence based on the VARK questionnaire and Multiple Intelligences Questionnaire respectively in second year medical students. Determining the relationship between individual preferences of students, based on their learning style and predominant type of intelligence and the perception of the modified Peyton’s four-step approach used to teach cardiac auscultation.

Methods: The opinion of participants 236 of the modified four-step approach was attained through the use of anonymous questionnaires. Using the VARK questionnaire, the participants’ learning style was defined. The predominant type of intelligence was determined by the Multiple Intelligences Question-naire.

Results: The kinesthetic style was the predominant unimodal learning style in second year medical students (in Polish and international students). The most predominant type of intelligence in Polish students was visual-spatial and mathematical and logical, while in international students the predominant types were visual-spatial and mixed type of intelligence. Quantitative analysis indicated that the modified Peyton’s approach is a valuable learning and teaching method for most students, independent of their predominant learning style or intelligence type. The exception was a small group of students with lin-guistic intelligence predominance according to the Multiple Intelligence Questionnaire, for which the Peyton method was more difficult.

Conclusions: This study proves that the modified Peyton’s approach is useful and effective didactic tool and can be successfully applied to most students. This is a new learning strategy for teaching cardiac auscultation in laboratory conditions in classes for a significant majority. Due to the fact that a group of students with a predominance of linguistic intelligence more often perceived the Peyton method to be difficult, it is worth combining traditional methods with new ones in class so that all students, regardless of unimodal learning style or prevailing type of intelligence, are taught satisfactorily.

Abstract

B a c k g r o u n d: The aim of the study was to evaluate the usefulness of the modified Peyton’s four-step approach in the teaching of cardiac auscultation and to determine students’ perception of Peyton’s four-step approach.

Me t h o d s: The opinion of the participants on the usefulness of the modifi ed four-step approach was attained through the use of anonymous questionnaires, voluntarily completed by students, and on the basis of semi-structured interviews conducted with a subset of students. 187 second-year students of our 6-year long curriculum were enrolled. They attended an obligatory Laboratory Training of Clinical Skills course. The average group size was 16 students.

R e s u l t s: The survey findings identified that 88.1% of participants found it helpful in developing their understanding of cardiac auscultation. 89.8% of all participants claimed that the new modified four-step approach facilitated memorization. The modified Peyton’s four-step method allows for better organization of classes in the opinion of 87.6% students. The advantages of the method were noticed by the majority of students.

C on c l u s i o n s: The modified Peyton’s four-step approach in the teaching of cardiac auscultation under laboratory conditions was perceived by students to be a comprehensible method that facilitates understanding and memorization. Th is approach allows for improved organization of classes. From the student’s perspective this method allows one to master the technique of cardiac auscultation in the classroom, through the increased demand of the participants’ attention, activity and involvement.
