Don’t scrap it just yet! Primary English as a Foreign Language education is associated with motivation and anxiety

English as a Foreign Language (EFL) education at the primary level does not only lead to progress in terms of language learning. A study has shown that learners from the south-west of Germany displayed higher levels of achievement motivation and lower levels of inhibiting exam anxiety the longer they were exposed to primary EFL classes.

Let’s get this out of the way: We can all agree that the German system of education is in trouble. More than 30 % of its ninth-formers do not develop sufficient reading skills. Likewise, more than 30 % of primary schoolers do not attain acceptable standards regarding their spelling skills. The situation is dire. But how can it be remedied?

One suggestion which has repeatedly been put forward is the enhancement of spelling practice at the primary level. Who could disagree? Another suggestion concerns primary English as a Foreign Language (EFL) education. Opinions here are less unequivocal, ranging from “enhance it” to “scrap it altogether”.

The more primary EFL lessons, the more motivation and the less exam anxiety

Truthfully, primary EFL has often been reported to yield linguistically questionable results. However, children learn more in these lessons than a foreign language: A study (my own, incidentally) published in the International Journal of Bilingual Education and Bilingualism shows that more than six years after leaving primary school, primary EFL lessons are associated with higher levels of motivation and lower levels of exam anxiety.

Data were collected in the federal state of Baden-Württemberg, in the south-west of Germany. At the time of data collection, participants were attending Year 11, with only one further year of secondary education ahead of them. When these students were attending primary school, primary EFL had not been fully implemented across the state. As a result, the majority (228 students) had not taken part in primary EFL at all, while others had experienced either two years (116 students) or four years (71 students) of primary EFL education.

The data on motivation, anxiety and verbal intelligence used in this study came from a database compiled for a project investigating the development of writing skills in relation to diverse educational settings, learner biographies and individual differences such as motivation, anxiety and cognitive capacities.

FLM 7-13: A questionnaire covering motivation and anxiety in adolescents

Motivation and anxiety were measured with the achievement motivation questionnaire FLM 7-13 (Fragebogen zur Leistungsmotivation für Schüler der 7. bis 13. Klasse; achievement motivation questionnaire for students from Year 7 to 13). The questionnaire consists of the following five individual measures:

  • Orientation towards performance and success: This scale combines hope of success with the desire to expand one’s own scope of competence.
  • Perseverance and effort: This scale combines the notion of hope of success with information on self-control and self-discipline.
  • Activating exam anxiety: Activating exam anxiety describes a positive emotion related to eagerness and the willingness to take risks in exam situations.
  • Inhibiting exam anxiety: This scale describes the debilitating aspect of anxiety, i.e. a passive fear of failure.
  • Fear of success: Fear of success is a psychological barrier to achievement. It is based on the belief that success will cause negative consequences such as social rejection.

In the context of primary EFL, three of these scales proved to be of long-term relevance: Orientation towards performance and success, perseverance and effort, and inhibiting exam anxiety (cf. Figure 1).

The chart is a bar chart representing three groups of learners: No primary EFL, 2 years and 4 years of primary EFL. The bars show that learners display more orientation towards performance and success as well as perseverance and effort and less inhibiting exam anxiety the longer they took part in EFL classes at the primary level.

The more primary EFL lessons, the more orientation towards performance and success

Out of the three groups of students, those who had attended four years of primary EFL displayed the highest levels of orientation towards performance and success more than six years later. Students with no primary EFL experience attained the lowest levels, with the two-year group being located in between.

This trend was found to be particularly visible as well as statistically significant with the following items which students responded to:

  • I aspire to be one of the best students at school.
  • I strive to perform better than most other students.

The more primary EFL lessons, the more perseverance and effort

The situation was similar for perseverance and effort: The longer students had taken part in primary EFL, the higher their scores. The tendency was particulary visible in response to the item “When I cannot perform a task immediately, I try everything to find a solution.”

The more primary EFL lessons, the less inhibiting exam anxiety

Regarding inhibiting exam anxiety, the reverse situation was observed: The longer students had experienced primary EFL, the lower their anxiety levels more than six years later.

The trend was particularly significant when students responded to the following statements:

  • When I have to perform a difficult task, I am afraid of failing.
  • I only take part in classroom discussions when I am certain that my answer is correct.

PSB-R 6-13: An intelligence test for adolescents

Cognitive capacities were measured with the intelligence test PSB-R 6-13 (Prüfsystem für Schul- und Bildungsberatung für 6. bis 13. Klassen). This test comprises scales on verbal intelligence, reasoning and concentration. Verbal intelligence, in turn, consists of subtests for word recognition, word fluency and verbal relations.

Early primary EFL is associated with weaker word recognition in German

Only one result regarding word recognition was found to be of relevance in the context of primary EFL (cf. Figure 2). This subtest consists of five individual tasks with a context-related heading and a list of twenty words, with a misspelling in each of the given words. Students have to recognize the word which fits the given heading and indicate where the misspelling occurs. The group which had taken part in four years of primary EFL education recognized significantly fewer words than the other groups. In other words, early onset of primary EFL education may impair learners’ ability to correctly identify words in German more than six years later.

The chart is a bar chart representing three groups of learners: No primary EFL, 2 years and 4 years of primary EFL. The bars show that learners' word recognition skills are worse the longer they took part in EFL classes at the primary level. Bars for word fluency and verbal relations are shaded in grey as findings were non-signficant.

Primary EFL: Don’t scrap it altogether!

So, is there a point in retaining primary EFL education? There certainly is. As participants in the study had no control of how much EFL education they would get, it is safe to assume that findings regarding motivation and anxiety are not based on any kind of selectivity within the system of education. In other words, we can assume that primary EFL influences students’ capacities for self-regulation. On the other hand, it may contribute to lower reading and spelling proficiency in German.

Decisions should certainly be taken on the basis of empirical rather than anecdotal evidence. Cutting down on the number of EFL lessons and years in primary schools seems fine, but ending primary EFL altogether would certainly be throwing the baby out with the bathwater.

Cognitive decline is associated even with mild Covid – Can we now talk about indoor air hygiene?

Cognitive impairment occurs even after asymptomatic or mild Covid disease, as a study conducted at Imperial College London shows. Cognitive decline affects memory, verbal intelligence and spatial thinking in particular. Long Covid sufferers experience the greatest losses.

Whether it is demands for a review of the containment measures adopted during the pandemic or shouts of “Covid is over!” to people who still have to or choose to wear masks: It is hard to avoid the impression that Germany has now definitely entered a post-pandemic reality. Consequently, air hygiene measures are now also being scaled back. HEPA filters in educational establishments – if ever they did exist – are now mostly meeting one of the following fates:

  • Scrapping
  • Storage “until the next pandemic”
  • Lack of maintenance
  • Ban on use.

Where none of these apply, they are often simply being ignored. After all, children, teenagers and young adults are supposed to forget the difficult times they experienced during the pandemic. Air hygiene would only get in the way. Or would it?

Study reveals cognitive decline after Covid-19

SARS-CoV-2, the virus responsible for the pandemic, seems unconcerned: Wastewater monitoring by the Robert Koch Institute, Germany’s federal agency for disease control and prevention, showed an unprecedented peak in wastewater contamination with SARS-CoV-2 in December 2023. This went largely unnoticed, while Germans never ceased to be puzzled over the numbers of staff on sick leave. However, the virus still demands to be noticed, as even mild Covid leads to a decline in cognitive abilities, as shown in a study by a research team led by Adam Hampshire of the Medical Faculty at Imperial College London. Their article was published in the New England Journal of Medicine.

People with long-term impairments following a Covid infection in particular report concentration problems, word-finding difficulties and similar symptoms which suggest a decline in cognitive abilities, i.e. abilities related to a person’s intelligence. In their study, the researchers therefore collected data using the Cognitron battery, an intelligence test that measures verbal and non-verbal reasoning and planning as well as working memory. More than 140,000 people took part in the study and almost 113,000 completed all tasks.

Since the researchers were primarily interested in finding out whether cognitive impairments depend on the duration and severity of a Covid illness, the participants were assigned to the following groups:

  • Not infected with Covid
  • Infected with Covid, but asymptomatic
  • Infected, with symptoms that resolved after less than four weeks
  • Infected, with symptoms that resolved after four to twelve weeks
  • Infected, with symptoms that resolved after more than twelve weeks
  • Infected, with symptoms that remained unresolved after more than twelve weeks and were still present at the time of data collection (“Long Covid”).

Earlier variants caused more damage than later ones

The fact that the virus kept changing during data collection was taken into account by sorting participants into groups according to the variant prevailing at the time of infection:

  • Original virus: up to 30/11/2020
  • Alpha (B.1.1.7.): 01/12/2020 to 30/04/2021
  • Delta (B.1.617.2): 01/05/2021 to 15/12/2021
  • Omicron (B.1.1.529): 16/12/2021 to 31/03/2022, which marked the end of data collection.

Good news first: With the transition to the Delta and, later, the Omicron variant, cognitive decline decreased. While it was still 0.32 standard deviations (SD) for the original virus, it is only 0.16 SD with Omicron, i.e. half as much.

Results may be represented in points on the IQ scale

Standard deviations are, for instance, used in intelligence tests to represent results. Thus, the IQ scale is defined by a  mean of 100 and a standard deviation of 15. Hence, if you move 15 points to the left and 15 points to the right from the mean value, this defines the range of intelligence that is commonly referred to as “average”. Average intelligence therefore means an IQ of 85 and 115. Slightly more than 68% of the population attain an IQ between 85 and 115. Values below 85 count as below average, values above 115 as above average.

A loss of 0.32 SD with the original virus therefore means a decline in cognitive abilities corresponding to 4.8 IQ points. Accordingly, a decline of 2.4 IQ points is to be expected with Omicron.

Cognitive decline occurs with all degrees of severity

A decline in cognitive abilities can even be observed with asymptomatic infections (see Figure 1). A loss corresponding to around 2.6 IQ points can be expected here. With symptomatic infections, the decline is similar regardless of how long it takes for the symptoms to resolve: A decline of between 3.5 and 3.9 IQ points was observed in those groups. People affected by Long Covid face the greatest problem: The frequently reported issues with reasoning, word finding and memory correspond to a loss of around 6.3 IQ points.

Memory is one of the most severely affected cognitive abilities (see Figure 2). Although all people who have been infected with Covid are affected, Long Covid sufferers have to cope with the greatest losses regarding immediate and delayed memory.

Chart shows cognitive decline regarding immediate and delayed memory after Covid-19

The area of verbal intelligence is also affected (see Figure 3). While there are similar losses with asymptomatic infection and symptoms which have not persisted, Long Covid sufferers again show the greatest decline for both word definitions and verbal reasoning based on analogies.

Spatial planning is also impaired in all groups (see Figure 4). Again, Long Covid sufferers are those who have to live with the steepest declines, although all groups who have been infected with Covid are concerned.

Educational institutions must protect learners’ cognitive skills

What does this mean for education? Schools take pride in providing learners with the best possible support to match their cognitive abilities. This should include ensuring that those cognitive abilities are not knowingly jeopardised. It is therefore still important to avoid Covid infection wherever possible.

The city of Bradford has shown how this can be done: The use of HEPA filters reduced the number of Covid infections amongst pupils by more than 20 %. The number of lessons cancelled due to teachers on sick leave can be reduced in the much the same way. Air filters will also reduce the number of Long Covid cases amongst teaching staff. Thus, the quality of teaching can be maintained, as cognitive impairments will lead to changes in lesson organisation and classroom management, and will also increase stress in teachers.

Indoor air hygiene must become a normal fact of life if we wish to maintain the cognitive performance of the current and future workforce.
