Abstract:Prostorske sposobnosti, ki jih Linn in Petersen opisujeta kot "spretnost za zastopanje, preoblikovanje, ustvarjanje in priklic simboličnih nejezikovnih informacij" (Linn & Petersen, 1985), se kot take ne poučujejo v šolah. Prepušča se jih naravnemu razvoju in s pomočjo nekaterih dejavnosti v otroštvu, ki so se pokazale, da so prediktorji zelo razvitih prostorskih sposobnosti (Sorby & Baartmans, 2000). Kljub temu je bil pomen visoko razvitih sposobnosti študentov STEM (znanosti, tehnologije, inženiringa in matematike) znanstveno dokazan (npr. Gohm, Humphreys, & Yao, 1998; Humphreys, Lubinski, & Yao, 1993; Lohman, 1988, 1994a, 1994b; Smith, 1964), kar neposredno nakazuje, da lahko prostorske sposobnosti pomembno vplivajo na uspeh ne le študija predmetov STEM, temveč tudi na uspeh v STEM karieri. Glavna hipoteza naše raziskave je bila: „prostorske sposobnosti je mogoče izboljšati s posebej razvitim programom z uporabo računalniškega programa Geogebra v obdobju najmanj enega meseca. Glede na prejšnje raziskave bodo izboljšane prostorske sposobnosti študentom predstavljale temelj za uspeh pri njihovem študiju in tudi v prihodnosti. " V naši raziskavi je bil uporabljen računalniški program GeoGebra kot glavno orodje za razvijanje prostorskih veščin. Eksperimentalno skupino je sestavljalo 35 moških (67,3%) in 17 žensk (32,7%), medtem ko je bilo v kontrolni skupini 33 moških (63,5%) in 19 žensk (36,5%). Vsi udeleženci so študirali na Fakulteti za naravoslovje in izobraževanje v Mostarju, Bosna in Hercegovina, s tem da so obiskovali različne študijske programe. Statistično značilna korelacija med točkami eksperimentalne skupine na začetnem in končnem preskusu prostorskih sposobnosti Smith in Whetton (1988) pomeni znaten skok v uspešnosti, ki ga v takšnem merilu lahko pripišemo le učinku eksperimentalnega programa (r = 0,833 ; p <0,01). Zato lahko trdimo, da je bila potrjena hipoteza 4, to je „razlike med začetnim in končnim preskušanjem prostorskih sposobnosti v eksperimentalni skupini so statistično pomembne“. Ugotovljena je bila tudi statistično pomembna povezava med rezultati kontrolne skupine na začetnem in končnem testu Smith in Whetton (1988) (r = 0,952; p <0,01). Čeprav razlika v njihovih povprečnih ocenah ni tako velika kot pri poskusni skupini, je to mogoče razložiti z učinkom treninga. Vendar pa je empirično dokazano, da ni mogoče ustvariti tako velikih razlik v rezultatih z uporabo metode testnega treninga (Zarevski, 2000). Ugotovljena je bila tudi statistično pomembna korelacija med rezultati eksperimentalne skupine na začetnem testu Smith in Whetton (1988) ter končnem prostorskem testu Newtona in Bristola (2009) (r = 0,474; p <0,01) ter med končnim testom Smith in Whetton (1988) ter končnim testom Newton in Bristol (2009) (r = 0,576; p <0,01), kar je mogoče razložiti tudi z učinkom eksperimentalnega programa. Zanimivo je, da smo med skupno oceno na končnem prostorskem preizkusu Newtona in Bristoll (2009) in povprečno oceno matematike našli statistično pomembne korelacije med povprečno oceno matematike v srednji šoli in vsemi rezultati katere koli od obeh skupin. (r = 0,272; p <0,05) in posebej med oceno eksperimentalne skupine (r = 0,392; p <0,05), ki pa je ni mogoče upoštevati, saj je upoštevanje rezultatov na končnem testu v najboljšem primeru nesmiselno. Zato lahko trdimo, da pomožna hipoteza 2, „znanje, pridobljeno med srednješolskim izobraževanjem, nima statistično pomembnega vpliva na razlike med uspešnostjo učencev v eksperimentalni skupini“, ni bilo potrjeno.

Title:Development and validation of spatial training curriculum using dynamic geometry software for university-level education
Abstract:Spatial abilities which are described by Linn and Petersen (1985) as “skill in representing, transforming, generating, and recalling symbolic, non-linguistic information“ (Linn & Petersen, 1985) are as such not trained nor they are taught in schools. They are left to develop naturally and on their, aided perhaps by some of the activities in childhood which have been shown to be predictors of highly developed spatial abilities, such as playing with construction toys, gender, math scores, previous experience in design-related courses such as drafting, mechanical drawing etc. (Sorby & Baartmans, 2000). Nevertheless, the importance of highly developed abilities for STEM (science, technology, engineering and mathematics) students has been scientifically proven (e.g. Gohm, Humphreys, & Yao, 1998; Humphreys, Lubinski, & Yao, 1993; Lohman, 1988, 1994a, 1994b; Smith, 1964), what directly implies that spatial abilities can have a significant impact on the success in not only studying STEM subjects, as well as success in STEM careers. The developed experimental programme employing GeoGebra 5 ran over the course of four weeks (1.5 hour per week) and was conducted at the Faculty of Science and Education in Mostar, Bosnia and Herzegovina. The sample consisted of first-year students, with 35 M and 17 F in experimental and 33 M and 19 F in control group. The programme content entailed following topics: 1) introduction to GeoGebra 5 and sketching basic geometrical objects, 2) measuring wooden objects, sketching them on paper and then in GeoGebra and v.v., 3) working with reflection and rotation in 2D using already designed GeoGebra apps, 4) solving various mathematical problems which require spatial visualisation by first sketching them on paper and then in GeoGebra. For pre-testing Smith and Whetton (1988) spatial test has been used, atop of which a background questionnaire has been administered, which also contained items hypothesised as possible spatial abilities predictors. For post-test Smith and Whetton (1988) test has been administered once again, along with Newton and Bristoll (2009) test. Dependent variables were 1) students’ success during the experimental programme and 2) students’ results on the spatial abilities pre-test and post-test, whereas the independent variable was students' gender. With the application of ANCOVA analysis it has been shown that average score was 55.89 for the experimental and 53.36 for control group (F=54.572, df=1, p=0.000, ηp2=0.406), from what it can be concluded that differences between the control and experimental group at initial testing of spatial abilities are not statistically significant. Results also showed that with the experimental group a statistically significant jump in performance on the post-test has occurred (t=-9.126, df=38, p<0.05), whereas with regard to the control group no statistically significant changes in performance have been noted (t=1.431, df= 43, p>0.05 ). Similarly, statistically significant correlation between the scores of the control group on the initial and final Smith and Whetton (1988) test has also been found (r=0.952; p<0.01), as well as between the scores of the experimental group on the initial and final Smith and Whetton (1988), where a significant jump in performance has been noted (r=0.833; p<0.01). No statistically significant differences have been found either with regard to gender (F=3.904; df=1; p=.052) or between the experimental and control groups and gender (F=1.688; df=1; p=.198). Statistically significant correlations between the average mathematics grade in high school and any scores of any of the two groups has been found between the total score on the final Newton and Bristoll (2009) spatial test and average mathematics grade (r=0.272; p<0.05).
