Abstract

BACKGROUND AND OBJECTIVE: This study examines the effect on third-grade students’ academic achievement and their pleasure and interest in lessons as a result of the incorporation of music into science classes.

MATERIAL AND METHODS: Sixty third grade Arab school children were studied before and after listing a Mozart Concerto. Their pleasure and interest in the lesson was evaluated using the 20-statement Barak questionnaire. Comparison was made between an initial 6 lessons without music and subsequent 6 lessons with music.

In another study at the Institute of Neurology and Neurosurgery in Havana, Cuba, continuous electroencephalographic monitoring (CEEG) was performed in 15 third-grade school children during 10 minutes at basal condition and for 10 minutes while listening to the same piece of music. 

RESULTS: Assessment scores in the science examination were significantly higher overall after listening to music. A clear increment of alpha and gamma absolute powers was found when listening to music, although for the alpha band this augmentation was significantly greater. An increment of the alpha band power was related to significantly better performance of spatial–temporal tasks when listening to music. Changes in the gamma frequency band represent cognitive processes. Hence, CEEG analysis adds to evidence that listening to music can increase enjoyment and  improve academic achievement among elementary school students.

CONCLUSION: We propose that music stimulates the formation of neural networks that prime the brain for learning. We recommend that teachers of core subjects, especially mathematics, science and languages, begin their lessons with 5 minutes of calm music.

1.INTRODUCTION

1.The effect of music on human development

The positive impact of music on human cognitive development, including fetal development, has been extensively studied [1]. The first three years of life are the most crucial in brain development [1-7]. A child’s interaction with his or her environment determines the level of development of brain architecture [4,8] as neurons multiply rapidly from the moment of birth, creating neural networks important for the rest of life [2,3,6-8]. Neurons not exposed to stimuli are less likely to connect - music is an important stimulus for the growth of functional neural networks throughout the brain [1-7]. The effect on brain development remains significant in school age children and is, therefore, of considerable interest in improving learning conditions in children’s formative years, especially in the classroom. An empirical study measuring differences in spatial intelligence showed an improvement of 43% in students learning to play the piano versus 11% in students studying computer science [3]. Music also impacts intellectual development, in particular the ability to listen and absorb language [7]. Listening to Mozart has been found to significantly help mothers cope with stress and improve their temperament [1-3,6,7] which in turn, may positively impact the environment at home for children. Music also encourages calm and good quality sleep [1,3,8]. Some researchers argue that intellectual improvement is only in the short term, and that if music does have an effect on a child's intelligence, the effect would be later – in the teenage years [1,6,8]. 

1.2 How music affects the brain

The main argument of most studies dealing with the effect of music on brain development [9-13] is that there are two important characteristics common to both language and music: both are used for communication; and, both have syntax with rules that dictate the correct combination of different components (the characters and words) [13, 15-17 ]. The findings of the various visualizations performed on the human brain indicate the existence of an area in the frontal lobe that allows the construction of syntax in music and language, while other parts of the brain address aspects related to verbal and musical processing [8]. When an individual listens to music, other areas located outside the auditory cortex are usually involved in thinking processes [6,9,10,15,17]. The visual, tactile and emotional experiences that an individual experiences earlier in life affect the specific location in which the human brain processes music [7,13,15-17]. When a musician plays an instrument, activity occurs in other areas such as the motor cortex and regions involved in planning and performing certain precisely timed movements. [17]. In 1998, Pentev showed that when musicians listen to piano playing, about 25% of their auditory cortical regions in the left hemisphere are highly activated [18,19]. This phenomenon is unique to music and does not occur with other sounds [7,15,17]. The researchers found that the expansion of the activated area was greater if the subject began to study music from a very young age. Studies in children suggest that musical experience at an early age promotes their cognitive development [7,9,10,13,15-17]. In 2004, an experiment was conducted in Canada among children aged four and five, in which brain responses were recorded while listening to tunes of the piano, violin and to pure tones. The findings of the study showed that children who were more exposed to music in their homes, showed stronger auditory brain activity compared to children aged approximately three years who were not exposed to music. The response to sounds among musicians is stronger in part because their auditory cortex is larger. There is a relationship between the percentage increase in the volume of the auditory cortex and the level of musical training. This implies that learning music increases the number of neurons and neural networks that process music. [18,19]

1.3 Cognitive processes in classroom learning

Effective teaching strategies focus on how information is presented in the classroom and how, children receive, organize and commit this information to memory. Classroom teaching efforts focus on increasing motivation, pleasure and attention in the classroom, and facilitating the process of building associations and connections children make between pieces of information [20-21]. Repetition and application of what is learned during class are two strategies in enhancing memory and understanding. Problem-solving skills further augment recall and understanding while promoting reasoning and executive functions such as decision-making [21-22]. 

In education psychology these teaching and learning strategies may be described in terms of four cognitive steps: attention, encoding information, storage (memory), and retrieval of information. Music may enhance any or all of these processes [22-23]. 

One possible mechanism rests on Stanovich's tripartite model of the mind – the interplay of the reflective, algorithmic and autonomous (intuitive) mind which may describe the connectivity of the frontal and prefrontal areas with the limbic system. The effect of music on the limbic system causes relaxation while priming the reflective (rational/reasoning) and algorithmic minds for learning [5-10]. In terms of Bloom’s taxonomy [30], (Figure. 1), priming or creating favourable conditions for learning may assist focus and concentration that enhances the acquisition of facts (knowledge), stimulates neuronal activity toward memory and recall, analysis and understanding, and algorithmic thinking essential to the application of knowledge and higher order cognitive executive functions such as decision making (31). Thus, cognition and neuronal pathways are implicated in measurable educational competencies and CEEG brain activity while listening to music would be expected to show increased alpha waves brought on by relaxing music and increased gamma wave activity during enhanced problem-solving and concentration as learning occurs in the classroom.

1.4 Study objective

The aim of this research was to investigate the effect of music on learning by testing three aspects of cognition: [1] pleasure and interest (attention) [2] recall and retrieval of information [3] brain activity while listening to music.

2. MATERIAL AND METHODS

This research is presented in two parts:

Israel: (1) pleasure and interest (attention) and (2) recall and retrieval of information were assessed in the classroom in an elementary school in Israel

Cuba: (3) brain activity after listening to music was investigated using CEEG in school children in Cuba.

2.1. Israel:

Participants

Research was conducted among 60 elementary school children - 24 female and 36 male - in grade 3 (aged 8 to 9 years) in Galilee. All participants were from middle class backgrounds as defined by Hollingshead and Redlich criteria [32]. IRB approval was obtained from the Research Committee of Oranim Academic College.

2.2. Procedure

Research was conducted in class during the teaching of the Science and Technology course: Materials and their Properties. The course comprised twelve 30-minute lessons, which proceeded as follows: The first five lessons were taught without music. Assessment was conducted during the sixth lesson (also without music). The next five lessons were conducted after participants listened to a piece of music. The twelfth lesson comprised assessment preceded by the same piece of music.

Music:

The piece of music used from the seventh to twelfth lesson was Mozart’s concerto for Flute and Harp Concerto in C major, K.299/297c also known as Mozart’s Relaxing Concerto for studying or Classical Study Music for Reading and Concentration played on YouTube for five minutes before each lesson (https://www.youtube.com/watch?v=vwIUJbIU57s&feature=youtu.be). Exactly the same excerpt of music was played for all six lessons to participants seated at their desks. The lesson began immediately after the music stopped.

Lesson delivery:

Lessons were conducted in Arabic by a single teacher in the format used for all Science and Technology teaching at the school.

Assessment:

On the sixth (without music) and twelfth (with music) lessons participants completed a questionnaire on (1) pleasure and interest (attention) (2) took a science examination on the topic on ‘Materials and their Properties’ that assessed overall academic performance (A) knowledge and recall, (B) understanding and application and (C) evaluation and synthesis

Motivation and pleasure were assessed using a 20-statement-Likert-scale-questionnaire (Appendix No. 1) devised by Barak [33] translated into Arabic.

Academic performance was examined using the national grade 3 written examination developed by the National Center for Science Teaching at Tel Aviv University (www.matar.ac.il) and the Ministry of Education in Israel translated into Arabic by a lecturer of the Department of Science at Oranim College (a local teacher-training college). The examination comprises open and closed questions on ‘Materials and their Properties’ and tested educational competencies of (A) knowledge and recall, (B) understanding and application and (C) evaluation and synthesis.

2.3. Statistical analysis

Paired t-test comparisons were performed with and without music as each participant served as his or her own control. Non-parametric Spearman’s rho correlations were performed in order to examine the impact of pleasure and interest on exam performance.

2.4 Cuba

Brain activity after listening to music was investigated using continuous EEG. CEEG is a rapidly evolving technology. Because the brain undergoes continuous and dynamic changes, CEEG was considered to be an effective method for real-time monitoring of functional brain changes after listening to music.

Participants

Fifteen school children in the third grade (aged 8 to 9) of “Gonzalo de Quezada” Havana School underwent CEEG analysis with IRB approval of the Institute of Neurology and Neurosurgery, Havana, Cuba.

Procedure

CEEG analysis

Participants were studied in our laboratory under conditions of controlled temperature (from 24 to 26O Celsius), noise attenuation and dimmed lights. CEEG was recorded from 19 standard locations over the scalp according to the 10-20 system: Fp1, Fp2, F3, F4, F7, F8, T3, T4, C3, C4, P3, P4, T5, T6, O1, O2, Fz, Cz, and Pz.

After careful cleansing of the skin, disc EEG tin electrodes were fixed using a conductor paste and connected to the input box of the digital Continuous EEG Monitoring system (Neuronic, S.A.). Monopolar leads were recorded using linked ears as a reference. Technical parameters for EEG were: gain 20,000; pass-band filters 0.1 -70 Hz; “notch” filter at 60 Hz; noise level of 2 μV (root mean squared); sampling frequency 200 Hz; and electrode-skin impedance never higher than 5 KΩ. For monitoring purposes, a 7 bipolar chest electrocardiogram (ECG) lead was simultaneously recorded with 0.5 to 30 Hz EEG filters. CEEG was recorded for 5 minutes without music (basal condition) and during 5 minutes after listening to the YouTube recoding of Mozart’s concerto for Flute and Harp Concerto in C major, K.299/297c (https://www.youtube.com/watch?v=vwIUJbIU57s&feature=youtu.be) in all 15 children.

3. RESULTS

3.1. Effects of Music on Educational Achievement

To test the effect of music on examination performance, a t-test was performed for dependent samples as shown in Table 1 below:

***p<0.001

Table 1: T-test for dependent samples to examine the differences between aspects of cognition and academic performance with and without music  

Scale from 0-100.

Overall mean examination scores (out of a total of 100) for all 60 participants were (64.81 + 7.44) without music and 85.22+6.46 after listening to music – an improvement of 31.5%. (significancet 15.25, p <0.001).

Out of 100 (A) knowledge and recall scores without music were 69.0+-8.81 and with music 89.23+ 6.23, an increase of 29.3% (significance t- 12.25, p<0.001). In (B) understanding and application scores without music were 65.22+8.49 and with music 85.63+_7.42, an increase of 31% (significance (t 13.32, p <0.001).  In (C) evaluation and synthesis scores without music were 60.23+6.2 and with music 80.8+-7.10, an increase of 34% (significance 16.7, p<0.001).

A strong correlation (Table 2 below) was found between examination scores of students who listened to music in A, B and C: the strongest between A, B and C (r = 0.82, p <0.001), then between A and B (r = 0.76, p<0.001); and finally between B and C (r = 0.68, p <0.001).

3.2. Effects of music on pleasure and interest

The effect of music on pleasure and interest was evaluated using a t-test for dependent samples as shown in Table 3 below:

 

Table 3: T-test for dependent samples to examine the differences between students' pleasure and interest (attention) in lessons with music and without music Scale from 1-5

Out of a total score of 5, pleasure an interest in lessons that incorporated music were 4.17+0.62 versus 2.20 +0.77, an increase of 89.5% (significancet 14.57, p <0.001).

3.3 Effect of attention on learning

Using Pearson's correlation, in lessons that incorporated music a strong correlation was found between pleasure and interest scores and examination scores (r = 0.77, p <0.001). There is also a significant positive relationship (r = 0.69, p <0.001) between pleasure and interest and A, pleasure and interest and B (r = 0.70, p <0.001) and pleasure and interest and C (r = 0.71, p <0.001) (Table 4).

3.4 CEEG analysis

In Figures 2, 3, and 4, we show representative subjects. There was a clear and statistically significant increment of the alpha absolute power comparing basal conditions and listening to music. Gamma absolute power also showed a significant incremental increase when listening music, but less than alpha absolute power.

Figure 3: Comparing basal condition and listening to music – incremental increase in both alpha and gamma absolute powers, although alpha band augmentation was greater.

4. DISCUSSION AND CONCLUSIONS

Listening to music for 5 minutes before each lesson and the examination resulted in a statistically significant improvement in examination performance overall and in specific educational competencies. Pleasure and interest (attention) were significantly improved by listening to music and affected overall academic performance as well as improving individual learning competencies – levels of cognition.

We propose a mechanism by which this improvement in cognition may have been achieved: CEEG analysis comparing basal conditions versus listening to music demonstrated incremental increases in the alpha and gamma bands, consistent with findings reported by Jausovec’s et al [34]. Regarding the gamma activity, oscillatory neural activity in the gamma frequency range (30-90 Hz) has been shown to accompany a wide variety of cognitive processes. Gamma-band activity and the synchronization of neural activity in the gamma-frequency range have been observed in different cortical and subcortical structures and have been associated with different cognitive functions. The results of EEG analysis in this research supports evidence that listening to music increases pleasure and interest (stimulation of the limbic pathway) which in turn primes the frontal and prefrontal areas for improved learning and cognition through stimulation of connecting neural networks. Music appears to stimulate all processes of cognition in learning - promoting the acquisition of basic knowledge, and its understanding, analysis and application.

There is neurochemical evidence to support these findings. Music increases the secretion of the neurotransmitter dopamine, which raises the level of pleasure and willingness to concentrate and learn. Dopamine is one of the neurotransmitters in the human brain that is also linked to serotonin. Dopamine is significantly involved in facilitating high cognitive functions, and, hence, also related to managerial/executive functions [35]. These findings are consistent with the reports of Crancic, Wilson, and Prior [36] that teaching music significantly improves spatio-temporal thinking skills and thinking skills. The findings of studies reviewed by Portowitz and Klein [37] indicate the existence of a significant positive relationship between music education and student academic achievement and social adaptation. However, few studies have examined how this process actually takes place. This research seeks to shed light on a possible mechanism of enhanced cognition through music priming of the cortico-limbic loop. If this mechanism is shown in further research to be the likely explanation, the implications for enhancing learning in the classroom are substantial. Music is a relatively inexpensive and accessible means of simulating learning among children. More research is needed to examine whether all music is equally effective, how long beneficial effects last and to what extent long term recall is enhanced by music. Portowitz and colleagues [38] reported the practice and evaluation of a musical education model called "Harmony," which uses new technologies and contemporary theories to improve learning. The findings of the study indicated that music has the ability to improve students' managerial functions, especially working memory, self-regulation and cognitive flexibility.

Fernandez [39] emphasized that music evokes movement and is a central and important force for the physical and mental development of the individual whose response to singing and music is mainly characterized by enjoyment derived directly from listening to music as a therapeutic tool.

Limitations and further research

There is clearly a need to replicate these results across language, mathematics and the teaching of all science topics in school children. While the effect of this particular Mozart piece is well documented, we want to know the effects of playing music for more than 5-minutes, playing music in the background during lessons, investigating the effects of other music (there are differences in what is perceived to be calming and what may be a distraction). While participants served as their own controls for the purposes of this research, we would like to know more about the confounding or additive effects of nutrition, sleep, exercise, mental health and, of course, the level of difficulty of the subjects learned during lessons. Assessment during or at the end of every lesson may elucidate the effect of music on learning versus performance in examinations – cognitive activity and related educational competencies would need to be carefully scrutinised, so that the most can be made of every learning opportunity, and both formative and summative assessment optimised.

Ideally, brain activity during lessons would be studied directly. There are obvious difficulties of simultaneous CEEG analysis in significant numbers of participants, and of performing this while lessons are in progress. Thus, for now, CEEG research and studies of cognition while learning in the classroom must be researched as separate entities.

In conclusion, we have shown the significant effect of music on learning in the classroom through improved academic performance. We have shown that music increases pleasure and interest (attention) in the lesson, and that improved attention significantly impacts learning and cognition at all levels.
