This study aims to analyse students’ extraneous cognitive load (ECL) in cell biology lectures. Participants in the study were 31 students of the Biology Education Department who attended the Cell Biology course from a university in Jakarta, Indonesia. The Cell Biology lectures include fours topics. The data of ECL were measured using questionnaires with a semantically differential scale, containing statements about students’ mental efforts in understanding the information received in the lectures. The data obtained were then tabulated, categorised according to the mental effort rubric, and made into percentage for each step of the VARK (Visual, Aural, Read/write, Kinaesthetic) approach. The results of the data analysis show that students' mental effort (ECL) in understanding each concept in Cell Biology lectures through the VARK approach is generally in the lower category. This is indicated by the very high percentage in the low category for  visual, aural, read/write, and kinaesthetic steps.          Keywords: Extraneous cognitive load, cell biology, VARK;

This study aims to determine the level of Extranous Cognitive Load (ECL) of students through mental effort in learning activities. Mental effort can be known and analyzed from external or foreign aspects, such as learning design and learning strategies undertaken. The source of the burden obtained in the learning process is known as ECL. The effectiveness of ECL is influenced by information and learning activities that contribute to the process of constructing students' cognitive schemes in learning process received. Good learning process happen if the ECL owned by student is in low category. ECL is measured by the mental effort of students in attending lecture activities. This research is a descriptive study, which was carried out on the fourth semester students of biology education who took part in the ethics and professional education classes. ECL measurements were measured using a mental effort questionnaire during the lecture. The data acquired is analyzed on the conversion of values in the low to high categories. The results showed that in the lecturing activities the student’s mental effort average was in the low category at 32.45. A low mental effort represents a low extranous cognitive load (ECL). It can be concluded that the learning strategies carried out in the ethics and education professional lectures can suppress ECL biology education students.

ABSTRACTA good learning strategy, should have to reduce the psychological burden of students when the learning process. The purpose of the study is to get an idea of the magnitude of the cognitive load of students in aproject based learningon the subject of learning audio-visual media. The method used in this research is quantitative descriptive. These research subjects are students of the fifth semester Biology Education Studies Program Pakuan University academic year 2016/2017 as many as 50 people. Student cognitive load was measured on three components, namely the mental effort students to describeextraneous cognitiveload(ECL), the ability to receive and process information to describeinstrisic cognitive load(ICL), and the learning outcomes to describegermane cognitive load(GCL). Measurement of ability to receive and process information usingtask complexity worksheet(Brunkenet al.,2010). Measurements mental effort using a questionnaireof subjectiveratting scale(Likert scale).Measurement of learning outcomes in the form essay, referring to the standard of reasoning developed by Marzanoet al(1993).The results showed that the ability to receive and process information very high which means that ICL is in the range of working memory, mental effort which means low student ECL is also low, and a fairly high learning outcomes and describe the magnitude of GCL. The results of the correlation calculations between the three components of cognitive load showed a negative correlation between the ICL with ECL (r =-0.017), the positive correlation between the ICL with GCL (r =0,252), while ECL with GCL has a value of a positive correlation (r = 0.135) , These results illustrate that the GCL obtained by students at least caused by ICL. It can be concluded that the student is still at a high cognitive load while attending classproject based learning.

An emergent research area in software engineering and software reliability is the use of wearable biosensors to monitor the cognitive state of software developers during software development tasks. The goal is to gather physiologic manifestations that can be linked to error-prone scenarios related to programmers’ cognitive states. In this paper we investigate whether electroencephalography (EEG) can be applied to accurately identify programmers’ cognitive load associated with the comprehension of code with different complexity levels. Therefore, a controlled experiment involving 26 programmers was carried. We found that features related to Theta, Alpha, and Beta brain waves have the highest discriminative power, allowing the identification of code lines and demanding higher mental effort. The EEG results reveal evidence of mental effort saturation as code complexity increases. Conversely, the classic software complexity metrics do not accurately represent the mental effort involved in code comprehension. Finally, EEG is proposed as a reference, in particular, the combination of EEG with eye tracking information allows for an accurate identification of code lines that correspond to peaks of cognitive load, providing a reference to help in the future evaluation of the space and time accuracy of programmers’ cognitive state monitored using wearable devices compatible with software development activities.
