Published: January 2023

Technological advances affect people’s working lives and contribute to the education system, especially in the learning process for generation 4.0. Generation 4.0 is a generation that is fully exposed to technological developments even from birth, so learning using technology will have a very good effect on them. However, conventional learning in schools is still dominated by conventional learning that uses textbooks as teaching media. Therefore, this study was conducted to determine the benefits of implementing interactive learning using the E-Learning Module. The data was collected through a review of international journals starting from 2015 to 2019. The findings show that one of the appropriate media used to teach the current 4.0 generation is interactive learning or known as learning, which uses interactive multimedia with interesting materials to motivate students to learn when and anywhere. This study also found that learning using the interactive learning module has advantages in pedagogical aspects such as collaborative learning, mixed learning, interactive learning, experiential learning, and problem-based learning.

Keywords: E-learning; Interactive Learning Module; Multimedia; Motivation; and Generation 4.0.

This research aims to describe and examine the obstacles and obstacles to the life process of religious moderation in Hindu learning in high school education in Mataram City. The city of Mataram consists of a reasonably plural community life, including the lives of people who adhere to diverse religions, with most Muslims. Tolerance among religious believers is capital in building hope for the development of a harmonious life in the community. Hindu learning in high schools becomes a habituation in building the foundation of moderate religious life. However, its integration in learning has obstacles that will undoubtedly hinder the acceleration of the development of religious moderation among students as a national resource. This study uses qualitative research with a case study approach with data collection techniques, namely observation, interviews and document studies. Based on the results of the study and analysis of the data, there are obstacles and obstacles in the form of not optimal learning in the learning process of religious moderation in Hindu religious education. This is because the material on religious moderation has not been directly written. However, in essence, it is contained in materials such as yajna values, catur asrama, upaveda, catur Warna, Vedic as a source of Hindu law and dasa Yama and nyama brata as a teaching of self-control in Hinduism. It is hoped that through this study, Hindu students at the high school level can understand and implement religious moderation learning in building a harmonious and tolerant life when entering society. This study can also be a reference library for relevant research in the future.

Published: January 2023

The analysis of existing surveys associated with the occurrence of gas shows in the well drilling, for the elimination of which a great amount of cost and time spent has been carried out. The most widespread of them are the complications of gas shows while pulling-out of drilling tool from the well. It was revealed that to prevent such complications, it is necessary to reduce the pressure of drilling mud under the bit of pulled-out drill stem from the well. Existing methods of reducing the fluid pressure under the drill bit of a pulled-out drilling tool lie in the fill-up of drilling mud through the borehole annulus with special fill-up devices. Therefore, the fill-up is conducted through various quantities of pulled-out flares. Considering this, we offer a method of specification of reducing fluid pressure under the bit of pulled-out drill stem via squeezing the drilling mud through the drilling tubes. The fill-up period is defined from the graphics of continuous changes of shearing strength in time obtained during the periodic deterioration of structure in the moments of a maximum value of shearing strength via stirring the drilling mud in shearing rates corresponding to the speed of pulling-out of drilling tool. The maximum value of the shearing strength is specified via the dependence provided

The paper deals with the issue of the rational use of well stock via the specification of the capacity increase of production in the long-term developed fields. The distribution graph of oil by all wells has been developed based on the statistical processing using a system approach of obtained field data. The hyperbolic nature of obtained distributions indicates the irregularity of the development and operation processes of the fields. The distributions of the total oil and water production by selected output intervals have been developed and analyzed as well. Mathematic models of obtained distribution functions have been specified. The results of studies carried out enable us to estimate the theoretic production capacity of reviewed well stock.

Since the effect of phase interrelation was not considered in hydrodynamic calculations of multiphase flows, such phenomena as mass transfer and migration of the particles of dispersed phases along the cross-section of the flow are related to the hydrodynamic paradox and the calculations did not meet the requirements of engineering practice. The paper reviews the issues of the formation of structural regimes in the vertical upward multiphase flow considering the effect of phase interaction (Bernoulli principle). The speed of transfer of the particles of dispersed phase into the flow core and the factors affecting them were estimated as well.

The paper studies the methods of prevention of necking of casings and in particular, production strings, as well as the complications occurring in the drilling process in the Caspian Sea as a result of clay flowing out and prediction of such kind of issues. Moreover, in the selection of production strings, “Stress Check” software program was used. One of the geological issues leading to the necking of casing is probably poorly cemented clay layers. In addition, the structure of the well drilled in Bulla-deniz field, formation pressure and the selection of casing for this well have been considered. In conclusion, the selection of casing to be lowered into the gas well in Bulla-deniz field has been executed via “Stress Check“ software program.
On the replacement in layer-heterogeneous formations (in the order of discussion)
Authors:   Azerbaijan State University of Oil and Industry, Mammadova E.V.
Published: January 2023

The oil fields of Azerbaijan are predominantly classified with layered formations with heterogeneous permeability. This is the reason for the fast watercut, formation of residual non-recoverable reserves in low-permeable reservoir zones, and for the decrease of production rate. The paper reviews the specification of the averaged value of phase permeability for the layers with decreasing permeability by depth in case when the water moves equally from upper to lower layers. The method described is generalized and effectively implemented provided that the curves of relative phase permeability corresponding to the end points change from layer to layer as well.

Published: January 2023

The paper deals with the development and employment of a new method providing more reliable joint of metallic consolidation piles with upper constructions of offshore hydrotechnical facilities operated in the Caspian Sea. With this purpose, new monolite iron-concrete units providing more reliable joint, particularly in the points of joints of consolidation piles and supporting collars of offshore piers and pier areas (in the inner space of collar structure) considering design features of mentioned facilities are developed and applied. The employment of these monolite iron-concrete units in hydrotechnical facilities operated in the offshore conditions has a great significance in the context of the extension of their service life after the turnaround up to thirty years, the assurance of their reliability and minimization of possible risks in the operation process. Nevertheless, the paper presents the fragments of the objects of the special state significance where developed monolite iron-concrete units are applied, and the arguments on the role of these units in the assurance of durability, hardness and reliability of these facilities provided as well.

The process was carried out in two hours in the laboratory conditions at 20 °С temperature. Dissolvan 4411, Alkan 415 and ND-12 demulsifiers were taken in 600 g/t, Gossipol resin – in 200 g/t, and А-1 and А-2 compositions – in 800 g/t ratio correspondingly. It was defined that two hours after adding Dissolvan 4411, Alkan 415, ND-12, А-1 and А-2 compositions at 20 °С temperature into the oil samples from Muradkhanly, Bulla-deniz, Balakhany-Sabunchu-Ramana, Neft Dashlary and Surakhany fields, the parameters of density, viscosity, water content, chloride salts and mechanical impurities sharply decrease. The composition of resin, asphaltene and paraffin compounds increases. The freezing temperature in the oil samples from Muradkhanly and Bulla-deniz fields do not change while in the samples from Balakhany, Neft Dashlary and Surakhany fields it dramatically reduces. The results of comparative analysis carried out at 20 °С temperature in the laboratory tests revealed that specifically А-1 and А-2 compositions mostly affect the improvement of physical-chemical characteristics of oil samples from Muradkhanly, Bulla-deniz, Balakhany-Sabunchu-Ramana, Neft Dashlary and Surakhany fields. It justifies that the employment of multi-functional compositions in the preparation to transportation of heavy oils is more efficient.

Authors: Boyko V. V. , Kravtsov O. V. , Lykhman V. M. , Kravtsova O. O.
Published: January 2023

Summary. Introduction. Burn injury remains one of the serious problems of clinical medicine. For successful spontaneous epithelization of surface burns in the prescribed time frame, it is necessary to create favorable conditions to reduce bacterial insemination and limit additional traumatization of dermal burns.

Goal. Evaluation of the clinical effectiveness of Arederma spray with probiotics for the local treatment of superficial burns.

Materials and methods. The results of complex local treatment of 26 patients with superficial burns are presented. Patients were divided into 2 clinical groups. The main group consisted of 14 patients who, before standard local treatment, underwent additional treatment of burn surfaces with a spray with probiotics. The comparison group consisted of 12 victims who underwent standard local therapy of burn surfaces. In patients of the main group, the burn area on average was (6.4 ± 1.8) % of body surface, in patients of the comparison group (5.9 ± 1.3) % of body surface. The effectiveness of the treatment was carried out on the basis of a microbiological study with the study of the wound process using cytological studies and visual assessment.

Results and discussion. The obtained results testify to the effectiveness of the local application of probiotics in the complex treatment of superficial burns due to the reduction of infection of the burn surface and the positive effect of the drug on epithelization processes, which made it possible to shorten the terms of inpatient treatment of burned patients.

Conclusions. The combined complex application of a neutral wound dressing and a spray containing probiotics optimizes the inflammatory process, reduces the infection of the burn surface with pathogenic microflora, which ensures epithelization of superficial burns in the prescribed time. The use of Arederma spray helped reduce the bacterial load on the burn surface at all stages of complex local treatment.

Published: January 2023

Summary. An analysis of clinical guidelines and literary articles on the treatment of patients with chronic hemorrhoids was carried out. Clinical recommendations do not differ in different countries regarding the approaches in terms of choosing options for conservative or operative therapy and methods of surgical treatment. Changing the diet, which allows you to eliminate constipation, normalize intestinal motility and obtain soft and voluminous stools, is an important stage of treatment. Pharmacological therapy has a low evidence base. Studies on the effectiveness of flavonoids for the treatment of chronic hemorrhoids are very heterogeneous, which does not allow for unequivocal conclusions. Rubber band ligation is the most effective procedure for the rapid elimination of chronic hemorrhoid symptoms, but it cannot effectively eliminate hemorrhoidal prolapse. Injection sclerotherapy has severe specific complications, which is why it is predicted to decrease in frequency for the treatment of chronic hemorrhoids. The only surgical approaches that experts recommend are open and closed hemorrhoidectomy. Stapler hemorrhoidopexy has a high frequency of specific complications, so it is necessary to approach its choice for the treatment of chronic hemorrhoids with caution. Doppler-guided hemorrhoid artery ligation is a physiological method of treatment, but it has a very high cost and is not economically viable. Conclusions. In patients with chronic hemorrhoids Goligher-1, Goligher-2, and in some cases - Goligher-3, “office procedures” can be chosen, but the patient should be informed about questionable results in the remote period. The operation of choice for patients with chronic Goligher-3 and Goligher-4 hemorrhoids remains open hemorrhoidectomy, the current modifications of which mainly include various technological approaches to cutting out nodes. Techniques in which a slightly different principle was proposed can be used as an alternative approach due to worse results when observing in distant terms.

A thermally stable composite reagent to polyvalent cations has been obtained, which reduces filtration and improves the anti-wear properties of clay suspensions. The values of the optimal reaction time and temperature were determined, the viscosity of the sampled polymer solutions was determined. The ratio of monomers and modification conditions are selected, this ensures a high conversion of monomers, and also increases the yield of the final product. The synthesized polymer of acrylonitrile and in the presence of fatty acids of gossypol resin and sulfuric acid in the pH = 3.5-5.5, with subsequent modification. The synthesized water-soluble polymer has a diphilic structure throughout the structure, the macromolecules of which contain a hydrophobic group and a hydrophilic part. They are able to adsorb and lower the interfacial free energy, which allows them to be classified as high-molecular surfactants.

Published: January 2023

Температурные напряжения в сопряженных системах, выполненных из разных материалов и в слоистых конструкционных материалах, даже при условии равномерного распределения температуры являются в первую очередь следствием разных механических свойств материалов, из которых выполнены сопряженные элементы или слои. В тоже время существенное влияние на общую картину температурных напряжений оказывают свойства сопряжения разнородных материалов и тип полученного соединения: склейка, сварка, или горячая посадка; идеальный контакт, свободное или частичное проскальзывание в разных направлениях. Предложено условие и метод совместного деформирования соосных цилиндров при разных условиях сопряжения по боковым поверхностям при неоднородных термомеханических характеристиках с учетом стесненного перемещения вдоль образующей для разных качественных условий взаимодействия на границе сопряжения. Метод позволяет существенно упростить задачу при условии термоупругого деформирования слое, а в случае вязкоупругого поведения с простыми ядрами релаксации позволяет получить аналитическое решение. Практическая значимость метода заключается в возможности моделирования технологических и остаточных напряжений в слоистых конструкционных цилиндрических системах, работающих в условиях циклического нагрева - охлаждения до высоких температур.

Temperature stresses in conjugate systems made of different materials and in layered structural materials, even under the condition of uniform temperature distribution, are primarily a consequence of the different mechanical properties of the materials from which the conjugate elements or layers are made. At the same time, the coupling properties of dissimilar materials and the type of joint obtained have a significant impact on the overall picture of temperature stresses: gluing, welding, or hot fit; ideal contact, free or partial slippage in different directions. The condition and method of joint deformation of coaxial cylinders under different conditions of coupling along the lateral surfaces with inhomogeneous thermomechanical characteristics, taking into account the constrained movement along the generatrix for different qualitative conditions of interaction at the interface, are proposed. The method makes it possible to significantly simplify the problem under the condition of thermoelastic deformation of the layer, and in the case of viscoelastic behavior with simple relaxation nuclei, it allows to obtain an analytical solution. The practical significance of the method lies in the possibility of modeling technological and residual stresses in layered structural cylindrical systems operating under conditions of cyclic heating and cooling to high temperatures.

This study proposed a dual-uncertainty two-stage fractional power system management (DUTSF-PSM) model to deal with uncertainties and dual objectives in the power management system of Ontario. This model integrates interval linear programming (ILP), chance-constrained programming (CCP), mixed-integer linear programming (MILP), and two-stage stochastic programming (TSP) methods into the framework of a linear fractional programming (LFP) model. Two-objective issues and capacity expansion schemes under multiple uncertainties can be addressed by the DUTSF-PSM model. Economic and environmental elements are considered in the objective function of the DUTSF-PSM model at the same time in order to get maximal system benefit with minimum environmental influence. This model can tackle effectively the tradeoff between the economic and environmental objectives. Through the DUTSF-PSM model for power systems in Ontario, the maximal system efficiency based on the least environmental influence under different levels of constraint-violation probabilities can be achieved. The results indicate that both hydroelectric and wind power have development potential when the economic and environmental factors are considered in the objective function at the same time. In addition, the results of factorial analyses reflected that the effect of CO2 emission of each power generation technology on the system revenue is most significant among the chosen three factors.

Results from 11 yr of radio timing for the eclipsing black widow millisecond pulsar (MSP) binary J1544+4937 is presented in this paper. We report a phase-connected timing model for this MSP, using observations with the Giant Metrewave Radio Telescope (GMRT) at multiple frequencies and with the Green Bank Telescope. This is the longest-duration timing study of any galactic-field MSP with the GMRT. While extending the timing baseline from the existing 1.5 yr to about a decade we report the first detection for a significant value of proper motion (μ

T
∼ 10.14(5) mas yr−1) for this pulsar. Temporal variations of dispersion measure (ΔDM ∼ 10−3 pc cm−3) manifested by significant determination of first-, second-, and third-order dispersion measure (DM) derivatives are observed along the line of sight to the pulsar. We also noticed frequency-dependent DM variations of the order of 10−3 pc cm−3, which could arise due to spatial electron density variations in the interstellar medium. This study has revealed a secular variation of the orbital period for this MSP for the first time. We investigated possible causes and propose that variation in the gravitational quadrupole moment of the companion could be responsible for the observed temporal changes in the orbital period.

However, measurements of the CRIR in low-to-intermediate density gas environments are rare, especially when background stars are absent. In this work, we combine molecular line observations of CO, OH, CH, and HCO+ in the star-forming cloud IC 348, and chemical models to constrain the value of the CRIR and study the response of the distribution of chemical abundances. The cloud boundary is found to have an A
V of approximately 4 mag. From the interior to the exterior of the cloud, the observed 13CO line intensities drop by an order of magnitude. The calculated average abundance of 12CO (assuming 12C/13C=65) is (1.2 ± 0.9) × 10−4, which decreases by a factor of 6 from the interior to the outside regions. The average abundance of CH (3.3 ± 0.7 × 10−8) is in good agreement with previous findings in diffuse and translucent clouds (A
V < 5 mag). However, we did not find a decline in CH abundance in regions of high extinction (A
V ≃ 8 mag) as previously reported in Taurus. By comparing the observed molecular abundances and chemical models, we find a decreasing trend of the CRIR as A

Rotation Measure Variations and Reversals of Repeating FRBs in Massive Binary Systems
Authors: Zhao Z. Y. , Zhang G. Q. , Wang F. Y. , Dai Z. G.
Published: January 2023

Recent observations discovered that some repeating fast radio bursts (FRBs) show complicated variations and reversals of Faraday rotation measures (RMs), indicating that the sources of these FRBs are embedded in a dynamically magnetized environment. One possible scenario is that repeating FRBs are generated by pulsars in binary systems, especially containing a high-mass companion with strong stellar outflows. Here we study the RM variations caused by stellar winds and a possible stellar disk. If the magnetic field is radial in the stellar wind, RMs will not reverse except if the magnetic axis inclination angle is close to 90°. For the toroidal magnetic field in the wind, RMs will reverse at the superconjunction. For the case of the toroidal field in the disk, the RM variations may have a multimodal and multiple reversal profile because the radio signals travel through different components of the disk during periastron passage. We also apply this model to FRB 20180916B. By assuming that its 16.35 day period is from a slowly rotating or freely precessing magnetar, we find that the secular RM variation can be explained by the periastron passage of a magnetar in a massive binary system. In addition, the clumps in the stellar wind and disk can cause short timescale (<1 day) variations or reversals of RM. Therefore, long-term monitoring of RM variations can reveal the environments of repeating FRBs.

In this study we examine the radial dependence of the inertial and dissipation range indices, as well as the spectral break separating the inertial and dissipation range in power density spectra of interplanetary magnetic field fluctuations using Parker Solar Probe data from the fifth solar encounter between ∼0.1 and ∼0.7 au. The derived break wavenumber compares reasonably well with previous estimates at larger radial distances and is consistent with gyro-resonant damping of Alfvénic fluctuations by thermal protons. We find that the inertial scale power-law index varies between approximately −1.65 and −1.45. This is consistent with either the Kolmogorov (−5/3) or Iroshnikov–Kraichnan (−3/2) values, and has a very weak radial dependence with a possible hint that the spectrum becomes steeper closer to the Sun. The dissipation range power-law index, however, has a clear dependence on radial distance (and turbulence age), decreasing from −3 near 0.7 au (4 days) to −4 [±0.3] at 0.1 au (0.75 days) closer to the Sun.

Data-driven simulation is becoming an important approach for realistically characterizing the configuration and evolution of solar active regions, revealing the onset mechanism of solar eruption events, and hopefully achieving the goal of accurate space weather forecasting, which is beyond the scope of any existing theoretical modeling. Here we performed a full 3D MHD simulation using the data-driven approach and followed the whole evolution process from the quasi-static phase to eruption successfully for solar active region (AR) NOAA 11429. The MHD system was driven at the bottom boundary by a photospheric velocity field, which is derived by the DAVE4VM method from the observed vector magnetograms. The simulation shows that a magnetic flux rope was generated by a persistent photospheric flow before the flare onset and then triggered to erupt by torus instability. Our simulation demonstrates a high degree of consistency with observations in the preeruption magnetic structure, the timescale of the quasi-static stage, the pattern of flare ribbons, as well as the time evolution of the magnetic energy injection and total unsigned magnetic flux. We further found that an eruption can also be initiated in the simulation driven by only the horizontal components of the photospheric flow, but a comparison of the different simulations indicates that the vertical flow at the bottom boundary is necessary for reproducing more realistically these observed features, emphasizing the importance of flux emergence during the development of this AR.

The effect credit term structure of monetary policy on firms' "short-term debt for long-term investment" behavior: empirical evidence from China
Authors: Zheng Liping , Liao Jia , Yu Yuan , Mo Bin , Liu Yun
Published: January 2023

This paper examines the effects and mechanism paths of monetary policy on firms' "short-term debt for long-term investment (SDFLI)" behavior using panel data of Chinese A-share listed firms from 2007-2019. The findings indicate that loose monetary policy suppresses corporate SDFLI behavior by lengthening corporate credit maturity structure through the credit maturity structure channel. In addition, heterogeneity analysis shows that loose monetary policy significantly inhibits the SDFLI behavior of state-owned enterprises(SOEs), non-high-tech firms, and firms in regions with high bank competition levels through the credit term structure channel, and the monetary policy credit term structure channel fails for non-state-owned enterprises(non-SOEs), high-tech firms, and firms in regions with low bank competition levels. The results of the heterogeneity analysis validate the plausibility that monetary policy affects firms' SDFLI behavior through the credit term structure channel.
Solvability of a nonlinear integro-differential equation with fractional order using the Bernoulli matrix approach

Published: January 2023

Under some suitable conditions, we study the existence and uniqueness of a solution to a new modification of a nonlinear fractional integro-differential equation (NFIDEq) in dual Banach space CE (E, [0, T]), which simulates several phenomena in mathematical physics, quantum mechanics, and other domains. The desired conclusions are demonstrated with the use of fixed-point theorems after applying the theory of fractional calculus. The validation of the provided strategy has been done by utilizing the Bernoulli matrix approach (BMA) method as a numerical method. The major motivation for selecting the BMA approach is that it combines Bernoulli polynomial approximation with Caputo fractional derivatives and numerical integral transformation to reduce the NFIDEq to an algebraic system and then derive the numerical solution; additionally, the convergence analysis indicated that the proposed strategy has more precision than other numerical methods. Finally, as a verification of the theoretical work, we apply two examples with numerical results by using [Matlab R2022b], illustrating the comparisons between the exact solutions and numerical solutions, as well as the absolute error in each case is computed.
Former les enseignants du supérieur à l’évaluation des textes des étudiants
Authors: Boch Françoise , Rinck Fanny , Sorba Julie
Published: January 2023

L’objectif du présent article est de contribuer à la formation des enseignants du supérieur, dans la perspective d’accompagner les étudiants dans la réécriture de leurs textes. Notre propos s’inscrit dans le champ des littéracies universitaires. Nous prenons appui sur une base de données élaborée dans le cadre du vaste projet français écri+, qui vise le développement de la formation à l’écrit et de la formation de formateurs à l’écrit dans l’enseignement supérieur. La base de données que nous avons conçue associe des extraits d’écrits d’étudiants et des commentaires produits par des enseignants sur ce qu’ils ont de problématique. Nous proposons de l’utiliser comme ressource pour la formation des enseignants du supérieur : l’observation guidée des extraits et commentaires pourrait favoriser leur réflexion sur le discours évaluatif, les normes et attendus des relecteurs et l’étayage didactique qu’implique un enseignement de l’écriture prenant en charge sa dimension processuelle. L’analyse de ces extraits et commentaires évaluatifs met en effet en évidence les normes en jeu dans la réception des écrits des étudiants et permet de s’interroger sur la manière de les rendre explicites à l’attention des scripteurs.
L’abandon aux études doctorales : un problème de direction?
Authors: Denis Constance , Lison Christelle
Published: January 2023

En parcourant la littérature scientifique et professionnelle en enseignement supérieur, il arrive fréquemment de lire qu’un doctorant sur deux abandonne ses études. Un tel taux d’abandon est-il alarmant? Est-il réaliste, voire souhaitable, que tous les doctorants achèvent leurs études? Quelles que soient les réponses à ces questions, il est généralement admis que l’encadrement joue un rôle prépondérant dans la persévérance aux études. Toutefois, il n’est pas aussi aisé qu’il y paraît de questionner les pratiques pédagogiques dans le cadre de l’encadrement. Dans cet article, les auteures s’appuient sur les résultats d’une recherche menée auprès de 20 doctorants et de 20 directeurs de recherche sur leurs expériences de l’encadrement à la recherche. Elles se penchent sur les potentiels effets de l’encadrement sur la persévérance aux études doctorales en trois temps : 1) un recrutement guidé, dès le début, permet d’éviter certains abandons; 2) la communication transparente, notamment pour gérer les inévitables deuils, affecte favorablement la poursuite des études; 3) l’insertion professionnelle, pensée tout au long du parcours, permet de cibler des objectifs concrets et de mieux amener l’étudiant à se préparer à la suite. Les questions et les réflexions ponctuent cet article de manière à apporter un regard scientifique et pragmatique tout en admettant le travail qui reste à effectuer pour valoriser l’encadrement à la recherche et ses limites.

Published: January 2023

The past two decades have ushered changes regarding the national science curriculum for K-12 students. Focusing on gifted and talented (GT) students, the literature reveals they clamor for unique experiences in constructing their knowledge in science education. This chapter explores science instruction for GT in this digital age using a Makerspace learning environment. Guided by the tenets of the Next Generation Science Standards, this chapter is supported by outlined standards and objectives connecting science content to GT learners' unique needs. The theory of socialization, specifically cognitive development coupled with the theory of constructivism, was used to ground this chapter. Results show Makerspace learning environments where GT students are exposed to inductive strategies and yield a greater return on student learning investments compared to the traditional deductive science classroom environment.
