Attitudes Toward Immigrants Are a Problem in Schools

In recent decades, it has long been known that humanitarian immigration has had harmful effects on Western societies. For example, the link between immigration and increased gang, drug, and sexual crime is quite clear (example, another).

Less has been said about other impacts of people from developing countries on Western nations. In Finland’s case, however, this is one of the reasons why, according to PISA tests, the country’s school system is no longer anywhere near the best in the world.

The matter was written about by a local Helsinki newspaper, which interviewed Ulla Talvensaari, who has worked as a primary school teacher for 25 years. To understand her views, my esteemed reader must know that in many Helsinki schools, the proportion of pupils with an immigrant background can exceed half of the student body.

According to the experienced teacher, insufficient Finnish language instruction for pupils with an immigrant background threatens to weaken the entire education system, from primary school to vocational studies. This is reflected in the fact that “today only the sharpest quarter of pupils can manage tasks that, at the start of my career around the turn of the millennium, were routine for the majority.”

This has led to a situation where “secondary school teachers wonder why children with such weak skills have been allowed to pass through primary school to higher levels. In vocational studies, people then question secondary school assessments. Eventually, in vocational schools, standards are lowered and incompetence becomes a burden for working life.”

Schools also do not take immigrant pupils’ lack of competence seriously, but instead “it is now difficult for a teacher to hold anyone back a grade or to give conditional passes. Many teachers end up lowering standards just to get everyone through the system.” In this way, they avoid being branded as racists for prolonging immigrant pupils’ time at school.

Thus, the teacher raises the question: “Is it really equality if there are huge gaps in skill levels within classrooms? We used to talk about the Gaussian curve. Most pupils were average, with only a small number being particularly weak or highly gifted. Now the middle group has almost disappeared, and classrooms consist mostly of extremes—either capable pupils or those with major learning challenges.”

As one way to improve the situation, the teacher also calls for more parental responsibility. In her view, “we [Finns] should demand that immigrant parents also practice Finnish regularly at home with their children.”

One can only hope that this teacher will be listened to both in Finland and elsewhere in Europe, and that society will abandon woke dogmas and instead uphold children’s right to learn at school—including those with immigrant backgrounds. This should remain the case even if their learning takes longer than that of the native population’s children.

Can climate models predict the distribution of warming?

According to climate models, greenhouse gases warm the Arctic region faster than the rest of the world, although there is some discrepancy between their predictions and actual measurements. Therefore, it has been more than interesting to follow the development of the northern sea ice over the years.

The National Snow & Ice Data Center (NSIDC) publishes two statistics on its development: the extent of the ice and its area. Of these, daily data is available for the extent, but only monthly averages for the area.

Now that India has suffered from an unprecedented heatwave and southern Europe has also been reported as one of the areas experiencing the most exceptional temperatures, it has been interesting to note that the latest data on the extent of the northern ice shows it is the 37th largest, or 10th smallest, for this time of year in the measurement history starting from 1979.

The monthly area statistic of the northern polar ice surprises even more, as in May, the ice area was the 23rd largest, or 24th smallest, in the statistics, thus roughly at the median value of the statistics. Therefore, the area of Arctic sea ice does not support the idea that the climate is warming fastest in the Arctic region. And even the estimate based on ice extent supports that only weakly.

All this raises questions about the ability of climate models to predict the distribution of warming caused by greenhouse gases across different parts of the globe. Or alternatively, about the reliability of climate statistics: in this regard, the measurements of the Arctic ice cover, carried out with easily interpretable methods, are surely among the most reliable, even though the two different measurement methods of the NSIDC produce surprisingly divergent views of the size of the northern polar ice cover.
