Portfolio Selection Using Multiple Factors: A Machine Learning Approach
Authors: Elmsili Bilal , Outtaj Benaceur
Published: January 2023

In this paper we present a novel framework for portfolio selection using deep neural networks and elastic net regularization: At the beginning of each month T, we follow a three-step methodology. First, for each stock, we use the previous seven years of data in order to compute over 36 firm-specific factors. Second, we perform features selection using elastic net regularization. Finally, we train a deep neural network in order to learn portfolio weights and hold this portfolio until the end of the month T. Compared with momentum, long-term reversal, and short-term reversal strategies, our approach demonstrates a superior performance in terms of the monthly rate of return (2% versus 1.22% for long-term reversal, 1.15% for momentum, and only 0.68% for short-term reversal), Sharpe ratio (21.67% versus 19.31% for momentum, 15.51% for long-term reversal, and 8.69% for short-term reversal), and the monthly risk-adjusted return (1.85% versus 0.74% for momentum, 0.72% for long-term reversal, and 0.31% for shortterm reversal). The results of our approach are all statistically significant at 1% level.

¿Lo técnico como factor de deshumanización?
Authors: Marcos Martínez Alfredo
Published: January 2023

Con frecuencia se asume que el desarrollo técnico implica un riesgo de deshumanización. En su versión divulgativa, este tesis se presenta como el peligro de que el ser humano sea sustituido por máquinas o que acabe esclavizado por las mismas o quizá fusionado con ellas. Lo que aquí sostengo es que lo técnico está en la entraña de lo humano, y que solo los usos e interpretaciones inadecuados de lo técnico y de lo propiamente humano pueden producir deshumanización. Curiosamente, el riesgo de deshumanización procede antes de una antropología desnortada que de lo técnico mismo. Guiado por esta idea, trato de esbozar el sentido de una vida propiamente humana, así como la posición de lo técnico al servicio de la misma. Sugiero, por último, que una actitud de serenidad ante lo técnico, propiciada por prácticas como el llamado silencio tecnológico, supone un antídoto adecuado contra el mencionado riesgo de deshumanización.

Vitamins and micronutrients in children with chronic kidney diseases
Authors: Ф.И. Руснак,
Published: January 2023

Хронические болезни почек у детей нашей страны развиваются на фоне гиповитаминоза, характерного для детского населения. И в наших, и в зарубежных исследованиях у детей с этим диагнозом отмечается дефицит витамина D. Однако снижение уровня витамина D в крови зависит от той нозологической единицы, которая лежит в основе развития хронической болезни почек. При тубулоинтерстициальных болезнях почек, для которых в основном характерно медленное прогрессирование, дефицит витамина D менее значителен. У детей с гломерулонефритом, особенно при применении глюкокортикоидов, дефицит витамина D и фосфорно-кальциевые нарушения более выражены. Сопутствующий вероятный дефицит витаминов С, В2, В6, Е, К и фолиевой кислоты еще больше усугубляет нарушения метаболизма витамина D и систему его рецепции, что требует проведения исследований для уточнения степени гиповитаминоза среди детей с хроническими болезнями почек и находящихся на заместительной почечной терапии. Гипервитаминоз А наблюдается уже на ранних стадиях хронических болезней почек из-за замедления выведения ретиноидов почками. Причем его уровни наиболее высоки у детей, получающих дополнительное питание, содержащее витамин А, по сравнению с одной только диетой. Повышение содержания ретиноидов в сыворотке крови значительно предопределяет развитие гиперкальциемии. При применении поливитаминных препаратов у детей с хроническими болезнями почек необходим дифференцированный подход, желательно обоснованный предварительным определением уровня витаминов в крови.

Chronic kidney diseases (CKD) in children of our country develop against the background of hypovitaminosis, characteristic of the child population. Both in our and foreign studies, vitamin D deficiency is noted in children with CKD. However, the decrease in vitamin D in the blood depends on the nosological unit that underlies the development of CKD. In tubulointerstitial kidney diseases, which are mainly characterized by slow progression of CKD, vitamin D deficiency is less significant. In children with glomerulonephritis, especially when using glucocorticoids, vitmin D deficiency and phosphorus-calcium disorders are more pronounced. The concomitant probable deficiency of vitamins C, B2, B6, E, K, folic acid further aggravates the metabolism of vitamin D and its reception system, requires research to clarify the degree of hypovitaminosis among children with CKD and those on renal replacement therapy. Hypervitaminosis A is observed already in the early stages of CKD due to a slowdown in the excretion of retinoids by the kidneys, and its levels are highest in children receiving supplemental nutrition containing vitamin A, compared with diet alone. Increased retinoids in the blood serum significantly predetermine the development of hypercalcemia. When using multivitamin preparations in children with CKD, a differentiated approach is necessary, preferably justified by the preliminary determination of vitamins in the blood.
Investigating the radiative effect of Arctic cirrus measured in situ during the winter 2015–2016

Published: January 2023

Abstract. The radiative energy budget in the Arctic undergoes a rapid transformation compared with global mean changes. Understanding the role of cirrus clouds in this system is vital, as they interact with short- and long-wave radiation,
and the presence of cirrus can be decisive as to a net gain or loss of radiative energy in the polar atmosphere. In an effort to derive the radiative properties of cirrus in a real scenario in this sensitive region, we use in situ measurements of the ice water content (IWC) performed during the Polar Stratosphere in a Changing Climate (POLSTRACC) aircraft campaign in the boreal winter and spring 2015–2016 employing the German High Altitude and Long Range Research Aircraft (HALO). A large dataset of IWC measurements of mostly thin cirrus at high northern latitudes was collected in the upper troposphere and also frequently in the lowermost stratosphere. From this dataset, we select vertical profiles that sampled the complete vertical extent of cirrus cloud layers. These profiles exhibit a vertical IWC structure that will be shown to control the instantaneous radiative effect in both the long and short wavelength regimes in the polar winter. We perform radiative transfer calculations with the uvspec model from the libRadtran software package in a one-dimensional column between the surface and the top of the atmosphere (TOA), using the IWC profiles as well as the state of the atmospheric column
at the time of measurement, as given by weather forecast products, as input. In parameter studies, we vary the surface albedo and solar zenith angle in ranges typical of the Arctic region. We find the strongest (positive) radiative forcing up to about 48 W m−2 for cirrus over bright snow, whereas the forcing is mostly weaker and even ambiguous, with a rather symmetric range of values down to -35Wm-2, over the open ocean in winter and spring. The
IWC structure over several kilometres in the vertical affects the irradiance at the TOA
via the distribution of optical thickness. We show the extent to which IWC profiles with a coarser vertical resolution can reflect this effect. Further, a highly variable heating rate profile within the cloud is found which drives dynamical processes and contributes to the thermal stratification at the tropopause. Our case studies highlight the importance of a detailed resolution of cirrus clouds and the consideration of surface albedo for estimations of the radiative energy budget in the Arctic.

Abstract. To investigate the impact of aging on the sources, volatility, and viscosity of organic aerosol (OA) in Chinese outflows, a high-resolution time-of-flight aerosol mass spectrometer (HR-AMS) coupled with a thermodenuder (TD) was deployed in the spring of 2018 in Dongying, which is
a regional receptor site of metropolitan emissions in the North China Plain
(NCP). The average mass concentration of PM1 is 31.5±22.7 µg m−3, which is mainly composed of nitrate (33 %) and OA (25 %). The source apportionment results show that the OA is mainly contributed by oxygenated OA (OOA) from secondary sources, including background-OOA (33 %) representing a background concentration of OA (2.6 µg m−3) in the NCP area, and transported-OOA (33 %) oxidized from urban emissions. The other two factors include aged hydrocarbon-liked OA (aged-HOA, 28 %) from transported vehicle emissions and biomass burning OA (BBOA, 5 %) from local open burning. The volatility of total OA (average C*=3.2×10-4 µg m−3) in this study is generally lower than that reported in previous field studies, which is mainly due to the high OA oxidation level resulting from aging processes during transport. The volatilities of OA factors follow the order of background-OOA (average C*=2.7×10-5 µg m−3) < transported-OOA (3.7×10-4µgm-3)< aged-HOA (8.1×10-4µgm-3)< BBOA (0.012 µg m−3). Extremely low volatilities in ambient air indicate that oligomers may exist in aged plumes. The viscosity estimation suggests that the majority of ambient OA in this study behaves as semisolid (60 %), liquifies at higher relative humidity (RH) (21 %), and solidifies (19 %) during
noon when the RH is low and the oxidation level is high. Finally, the
estimated mixing time of molecules in 200 nm OA varies dramatically from
minutes at night to years in the afternoon, emphasizing the need to
consider its dynamic kinetic limits when modeling OA. In general, the
overall results of this study improve our understanding of the impact of aging on OA volatility and viscosity.
Storm time polar cap expansion: interplanetary magnetic field clock angle dependence
Authors: Tulegenov Beket , Raeder Joachim , Cramer William D. , Ferdousi Banafsheh , Fuller-Rowell Timothy J. , Maruyama Naomi , Strangeway Robert J.
Published: January 2023

Abstract. It is well known that the polar cap, delineated by the open–closed field line boundary (OCB),
responds to changes in the interplanetary magnetic field (IMF).
In general, the boundary moves equatorward when the IMF turns southward and contracts
poleward when the IMF turns northward. However,
observations of the OCB are spotty and limited in local time,
making more detailed studies of its IMF dependence difficult.
Here, we simulate five solar storm periods with the coupled model consisting of the Open
Geospace General Circulation Model (OpenGGCM) coupled with the Coupled Thermosphere Ionosphere
Model (CTIM) and the Rice Convection Model (RCM),
i.e., the OpenGGCM-CTIM-RCM, to estimate the location and dynamics of the OCB.
For these events, polar cap boundary location observations are also obtained from Defense Meteorological
Satellite Program (DMSP) precipitation spectrograms and compared with the model output.
There is a large scatter in the DMSP observations and in the model output.
Although the model does not predict the OCB with high fidelity for every observation,
it does reproduce the general trend as a function of IMF clock angle.
On average, the model overestimates the latitude of the open–closed field line boundary
by 1.61∘. Additional analysis of the simulated polar cap boundary dynamics across
all local times shows that the MLT of the largest polar cap expansion closely correlates
with the IMF clock angle, that the strongest correlation occurs when the IMF is southward, that
during strong southward IMF the polar cap shifts sunward, and that the polar cap rapidly
contracts at all local times when the IMF turns northward.
Peatlands and their carbon dynamics in northern high latitudes from 1990 to 2300: a process-based biogeochemistry model analysis
Authors: Zhao Bailu , Zhuang Qianlai
Published: January 2023

Abstract. Northern peatlands have been a large C sink during the Holocene,
but whether they will keep being a C sink under future climate change is
uncertain. This study simulates the responses of northern peatlands to
future climate until 2300 with a Peatland version Terrestrial Ecosystem
Model (PTEM). The simulations are driven with two sets of CMIP5 climate data
(IPSL-CM5A-LR and bcc-csm1-1) under three warming scenarios (RCPs 2.6, 4.5 and
8.5). Peatland area expansion, shrinkage, and C accumulation and
decomposition are modeled. In the 21st century, northern peatlands are
projected to be a C source of 1.2–13.3 Pg C under all climate scenarios
except for RCP 2.6 of bcc-csm1-1 (a sink of 0.8 Pg C). During 2100–2300,
northern peatlands under all scenarios are a C source under IPSL-CM5A-LR
scenarios, being larger sources than bcc-csm1-1 scenarios (5.9–118.3 vs.
0.7–87.6 Pg C). C sources are attributed to (1) the peatland water table depth
(WTD) becoming deeper and permafrost thaw increasing decomposition rate; (2) net primary production (NPP) not increasing much as climate warms because
peat drying suppresses net N mineralization; and (3) as WTD deepens,
peatlands switching from moss–herbaceous dominated to moss–woody dominated,
while woody plants require more N for productivity. Under IPSL-CM5A-LR
scenarios, northern peatlands remain as a C sink until the pan-Arctic annual
temperature reaches −2.6 to −2.89 ∘C, while this threshold is −2.09
to −2.35 ∘C under bcc-csm1-1 scenarios. This study predicts a
northern peatland sink-to-source shift in around 2050, earlier than previous
estimates of after 2100, and emphasizes the vulnerability of northern
peatlands to climate change.
Short communication: age2exhume – a MATLAB/Python script to calculate steady-state vertical exhumation rates from thermochronometric ages and application to the Himalaya
Authors: van der Beek Peter , Schildgen Taylor F.
Published: January 2023

Abstract. Interpreting cooling ages from multiple thermochronometric systems and/or
from steep elevation transects with the help of a thermal model can provide
unique insights into the spatial and temporal patterns of rock exhumation.
Although several well-established thermal models allow for a detailed
exploration of how cooling or exhumation rates evolved in a limited area or
along a transect, integrating large, regional datasets in such models
remains challenging. Here, we present age2exhume, a thermal model in the
form of a MATLAB or Python script, which can be used to rapidly obtain a
synoptic overview of exhumation rates from large, regional
thermochronometric datasets. The model incorporates surface temperature
based on a defined lapse rate and a local relief correction that is
dependent on the thermochronometric system of interest. Other inputs include
sample cooling age, uncertainty, and an initial (unperturbed) geothermal
gradient. The model is simplified in that it assumes steady, vertical
rock uplift and unchanging topography when calculating exhumation rates. For
this reason, it does not replace more powerful and versatile
thermal–kinematic models, but it has the advantage of simple implementation
and rapidly calculated results. We also provide plots of predicted
exhumation rates as a function of thermochronometric age and the local
relief correction, which can be used to simply look up a first-order
estimate of exhumation rate. In our example dataset, we show exhumation
rates calculated from 1785 cooling ages from the Himalaya associated with
five different thermochronometric systems. Despite the synoptic nature of
the results, they reflect known segmentation patterns and changing
exhumation rates in areas that have undergone structural reorganization.
Moreover, the rapid calculations enable an exploration of the sensitivity of
the results to various input parameters and an illustration of the
importance of explicit modeling of thermal fields when calculating
exhumation rates from thermochronometric data.
SUHMO: an adaptive mesh refinement SUbglacial Hydrology MOdel v1.0
Authors: Felden Anne M. , Martin Daniel F. , Ng Esmond G.
Published: January 2023

Abstract. Water flowing under ice sheets and glaciers can have a strong influence on ice dynamics, particularly through pressure changes, suggesting that a comprehensive ice sheet model should include the effect of basal hydrology. Modeling subglacial hydrology remains a challenge, however, mainly due to the range of spatial and temporal scales involved – from subglacial channels to vast subglacial lakes. Additionally, networks of subglacial drainage channels dynamically evolve over time. To address some of these challenges, we have developed an adaptive mesh refinement (AMR) model based on the Chombo software framework. We extend the model proposed by Sommers et al. (2018) with a small but significant change to accommodate the transition from unresolved to resolved flow features. We handle the strong nonlinearities present in the equations by resorting to an efficient nonlinear full approximation scheme multigrid (FAS-MG) algorithm. We outline the details of the algorithm and present convergence analysis results demonstrating its good performance. Additionally, we present results validating our approach, using test cases from the Subglacial Hydrology Model Intercomparison Project (SHMIP) (de Fleurian et al., 2018).
We finish by presenting a more complex, 100 km-by-100 km synthetic test case with peaks and valleys that we use to investigate the effective pressure distribution as the number of AMR levels increases. These preliminary results suggest that a minimum spatial resolution is needed to properly capture channel features, but additional work is required to precisely quantify this and its impact on accurately modeling the coupled ice sheet–hydrology system. The efficiency of our approach, relying on localized refinement, is also demonstrated. Future work will include coupling the SUbglacial Hydrology MOdel (SUHMO) with the BISICLES AMR ice sheet model (Cornford et al., 2013), both built on the same numerical framework.
An empirical model to calculate snow depth from daily snow water equivalent: SWE2HS 1.0
Authors: Aschauer Johannes , Michel Adrien , Jonas Tobias , Marty Christoph
Published: January 2023

Abstract. Many methods exist to model snow densification in order to calculate the depth of a single snow layer or the depth of the total snow cover from its mass. Most of these densification models need to be tightly integrated with an accumulation and melt model and need many forcing variables at high temporal resolution. However, when trying to model snow depth on climatological timescales, which is often needed for winter tourism related applications, these preconditions can cause barriers. Often, for these types of applications empirical snow models are used. These can estimate snow accumulation and melt based on daily precipitation and temperature data, only. To convert the resultant snow water equivalent time series into snow depth, we developed the empirical model SWE2HS. SWE2HS has been calibrated on a data set derived from a manual observer station network in Switzerland and validated against independent data from automatic weather stations in the European Alps. The model fits the calibration data with root mean squared error (RMSE) of 8.4 cm, coefficient of determination (R2) of 0.97 and BIAS of 0.2 cm and is able to reach RMSE of 20.5 cm, R2 of 0.92 and BIAS of 2.5 cm on the validation data. The temporal evolution of the bulk density can be reproduced reasonably well on both data sets. Due to its simplicity, the model can be used as post-processing tool for output of any other snow model that provides daily snow water equivalent output. SWE2HS is available as a Python package which can be easily installed and used.
Short communication: Part contour error prediction based on LSTM neural network
Authors: Zhang Yun , Liang Guangshun , Cao Cong , Zhang Yun , Li Yan
Published: January 2023

Abstract. Machine tools are subject to multiple sources of error during
machining, resulting in deviations in the dimensions of the part and a
reduction in contour accuracy. This paper proposes a contour error
prediction model based on a long short-term memory (LSTM) neural network,
taking hexagonal recess machining as an example and considering the power,
vibration, and temperature signals that affect the contour error. The
experimental data show that the model can accurately predict the contour
error of the machined part. A more accurate and robust contour error
prediction model can provide data support for online compensation of contour
errors.

Authors: Pavlyuk K. , Leonov M. , Akobyan A. , Sinitskaya T. , Gospirovich O. , Artemova E. , Yeleubayeva Zh.
Published: January 2023

Relevance: Cytological criteria of tumors in exudate fluids are associated with certain subjective difficulties, one of which is the differential
diagnosis of proliferating mesothelial and adenocarci-noma cells.
The study aimed to increase the informational value of cytological diagnostics in a multidisciplinary hospital.
Methods: From 2018 to 2021, 10,082 serous cavity effusions (pleural – 8,166 (81%), abdominal cavity – 1,512 (15%), pericardial – 404 (4%))
were included in the cytological examination. Micro-scopic examination of traditional preparations was carried out, and immunocytochemical
(ICC) ex-amination was carried out in difficult diagnostic situations.
Results: Analysis of the study showed that by the traditional cytological method in effusion fluids in women, metastatic lesions of the serous
cavities were diagnosed in 672 cases (58%), mainly due to the progression of breast cancer (26%). In men, pleurisy was mainly due to metastasis
of adenocar-cinoma of the lung – 266 cases (23%). ICC research increased the diagnostic accuracy of cytological examination by 62-93% and the
specificity – by 95-99%.
Conclusions: An algorithm for conducting ICH studies, differing in the number of panels of mono-clonal antibodies used to determine the
histological form and organ - the source of the tumor, has been developed. In specific cases, conducting ICR studies with 2-3 monoclonal antibodies
may be quite enough to confirm the histological form of the tumor and, where necessary, perform additional ICR studies without significant loss
of time for obtaining results.

Published: January 2023

Purpose: The aim of the study is the comparative analysis of the operating time, blood loss during surgery, postoperative discomfort, and pain, hospital stay, cost-effectiveness, and patient satisfaction in patients undergoing laparoscopic cholecystectomy and conventional cholecystectomy in UMHATEM "N.I.Pirogov". Material and Methods: For a one-year period (from 01.01.2018 to 01.01.2019) 512 patients with calculous cholecystitis were operated on the Department of General, Visceral, and Emergency surgery on UMHATEM "Pirogov". In 487 of these cases, laparoscopic cholecystectomy was performed (group I), the remaining 25 cases were treated with conventional cholecystectomy (group II). Women with laparoscopic cholecystectomy (group I) were 392 (75.82%), men 95 (24.18%). From the open surgery cohort (group II), women were 19 (75.41%), men 6 (24.59%). The age in this retrospective analysis varied from 18 to 83 years (average 52.7 years). Results: From group I (lap. cholecystectomy), women were 392 (80.49%), men 95 (19.51%). In group II (open cholecystectomy), women were 19 (76%), men 6 (24%). Age in this retrospective analysis ranged from 18 to 83 years (average 52.7 years) for both groups. There was no significant difference between demographic variables in the two groups. The operating time varied between 23 and 165 min (average 39.4 min) for group I and 35 to 104min (average 44.6min) for group II respectively. The hospital stay was recorded from 48 hours to 7 days (2.7 days on average) for group I and 3 to 9 days (average 4.5 days) for group II respectively. Surgical morbidity included 12 patients (operative wound suppuration, ileus, postoperative hernia, jaundice), 7 from group I (1.44%) and 5 from group II (20%), which was considered a significant difference. Conclusion: Laparoscopic cholecystectomy is an easy intervention, reduced time-consuming procedure, with shortened complication rates compared to open cholecystectomy. It completely debates an advantage of a decreased hospital stay and early return to work compared to open surgery.

The experiment was laid out in Randomized Block Design (RBD) with three replications and nine treatments viz.T1 (Farm Yard Manure @ 40 t ha-1), T2 (Compost (NADEP) @ 18 t ha-1), T3 (Vermicompost @ 13.5 t ha-1), T4 (Poultry manure @ 6.6 t ha-1) and T5 (Farm Yard Manure @ 40 t ha-1 + Soil application of Azotobacter+ PSB @ 5 kg ha-1 each), T6 (Compost (NADEP) @18 t ha-1 + Soil application of Azotobacter+ PSB @ 5 kg ha-1 each), T7 (Vermicompost @ 13.5 t ha-1 + Soil application of Azotobacter+ PSB @ 5 kg ha-1 each), T8 (Poultry manure @ 6.6 t ha-1 + Soil application of Azotobacter+ PSB @ 5 kg ha-1 each), T9 Control (RDF- 200:100:100 NPK Kg/ha). The various observations in respect of vine growth and yield of watermelon were recorded periodically. From the present findings, it was observed that the growth parameters in respect length of main vine, number of leaves, number of primary branches, chlorophyll index, days for first female flower appearance, internodal distance and male female ratio were found better with Vermicompost @ 13.5 t ha-1+ soil application of Azotobacter +PSB @ 5kg ha-1 each. Yield parameters viz days required for edible maturity, number of fruits per vine, average fruit weight kg, fruit yield kg per vine and fruit yield per ha-1 (tons) were found to be maximum with Vermicompost @ 13.5 t ha-1+ soil application of Azotobacter +PSB @ 5kg ha-1 each.

O currículo de ciências na perspectiva dos professores da rede estadual de ensino de São Paulo
Authors: Carvalho Celso Do Prado Ferraz de , Vicente Luciane Da Silva
Published: January 2023

O artigo em tela tem como objeto de problematização o currículo da disciplina de ciências da Secretaria de Educação do Estado de São Paulo, elaborado por um grupo de especialistas definidos pela SEESP, sem a participação dos professores.  Apresentamos dados de pesquisa que apresentam a compreensão que os professores de ciências possuem do currículo oficial e como esse entendimento tem impactado em seu trabalho. Realizamos um conjunto de entrevistas semiestruturadas com professores de Ciências, que tratou da experiência, percepção e compreensão que eles possuem do currículo e de como impactou a prática escolar.  As entrevistas foram analisadas por meio da articulação entre técnicas de pesquisa qualitativa e metodologia da análise de conteúdo. Os resultados dessa investigação indicam que a Currículo Oficial para a Rede Estadual de Ensino do Estado de São Paulo desconsidera as peculiaridades dos contextos escolares, não disponibiliza recursos didáticos e infraestrutura adequada para que os professores realizem seu trabalho. Além disso, sua concepção, reduz os professores à meros reprodutores de um currículo construído sem a participação dos envolvidos diretamente no processo educativo da rede.
Os significados de Intenção e Disposição para aprender na Teoria da Aprendizagem Significativa
Authors: Belmont Rachel , Da Cunha Karla Maria Castello Branco , Lemos Evelyse Dos Santos
Published: January 2023

O conceito Aprendizagem Significativa, ainda polissêmico no contexto educativo e da sua investigação, foi cunhado no escopo de uma teoria que explica seu processo, condições de ocorrência e facilitação. Intenção e disposição (para aprender) são momentos diferentes da aprendizagem, mas comumente assumidos como sinônimos em estudos de língua portuguesa que se baseiam na Teoria. O objetivo deste manuscrito é apresentar reflexões sobre os significados dos referidos conceitos presentes na obra original de Ausubel, publicada em 2000, e em sua tradução para o português, em 2003. A análise do texto original revela inconsistência na tradução de termos essenciais para a compreensão do processo da aprendizagem, especialmente o meaningful learning set. Este fato pode ter contribuído para um entendimento superficial desses significados. Propomos o uso do termo “learning set com significado” pela complexidade do conceito e inexistência de palavra em português com correspondência direta para o seu significado. Por fim, sugerimos maior atenção a tais conceitos e que novos estudos sejam realizados.
Aprendizagem ativa com significado
Authors: Moreira Marco Antonio
Published: January 2023

O ensino de ciências tradicional, centrado no professor que “dá a matéria”, tentando explicá-la o melhor possível, é pior do que ineficaz, é anticientífico (Carl Wieman). O ensino não pode ser monológico, mas sim dialógico (Paulo Freire), e o aluno deve participar ativamente no processo ensino-aprendizagem. No entanto, participação ativa não é simplesmente “mão na massa”, pois deve envolver, fundamentalmente, aspectos cognitivos significativos. Por mais ativo que seja o ensino, por mais tecnológico que seja, a aprendizagem tem que ser significativa (David Ausubel), i.e, com significado, compreensão, capacidade de explicar, de aplicar conhecimentos adquiridos, declarativos ou procedimentais. Aprendizagem ativa sem significado não tem sentido.
