However, three candidates were requested to exit the assessment process because they did not adhere to the prescribed assessment regulations. Consequently, a total number of respondents This was conducted over six assessment sessions.
Measuring instruments Trade Aptitude Test Battery: The aim of the Trade Aptitude Test TRAT battery is to assist in the selection of potential students for admittance into technical institutes and colleges.
The test battery also indicates the candidates' potential to progress and successfully finish training in a specific technical field Taljaard, The authors used five sub-tests from the TRAT battery to ascertain the identified technically specified aptitudes required for the automotive operator position.
The key differences with regard to purpose, items per instrument and time limits of these sub-tests are discussed. This tool determines an aspect of the candidate's two-hand eye coordination, a facet of psychomotor coordination. The sub-test is based on the postulation that the capacity to simultaneously, rapidly and accurately pencil in circles, by employing a pencil in each hand, between the provided pairs of concentric circles is a valid indicator of two-hand-eye coordination.
The instrument consists of 72 items with a 2-min test completion time Taljaard, The intention of this sub-test is to establish the candidate's hand-eye coordination, another facet of psychomotor ability.
The test rests on the hypothesis that the skill required to pencil in an unbroken line rapidly and precisely, by hand, between circular zones by going above one and below the other, without contacting the zones or picking up one's pencil, is regarded as a valid gauge of hand-eye coordination.
Two minutes are allowed to attempt items in this sub-test Taljaard, The aim of this sub-test is to reveal the candidate's ability to build illustrations mentally of mechanical parts to shape a provided mechanical object. This sub-test comprises 25 multiple-choice type questions and a time limit of 25 min Taljaard, The spatial perception 2-D sub-test: This sub-test seeks to disclose the candidate's two-dimensional spatial perceptual ability.
The test rests on the assumption that the degree to which a candidate sees 2-D geometrical shapes and is able to mentally rotate them on a flat surface is regarded to be a valid measurement of 2-D spatial perceptual ability. The sub-test comprises multiple-choice type questions with a time limit of 17 min for completion Taljaard, The spatial perception 3-D sub-test: This instrument is aimed at determining the candidate's three-dimensional spatial perceptual ability.
This test rests on the assumption that the degree to which a candidate is able to visualise mentally, turn and merge 3-D figures, in order to formulate them to appear similar to a given representation and to shape mentally a 3-D composition from a 2-D plan, is a valid measurement of his or her 3-D spatial perceptual ability. This tool consists of two sections: Section 1 comprises 13 multiple-choice type questions to be attempted in 7 min; Section 2 has 12 multiple-choice type questions to be completed in 9 min Taljaard, The reliability coefficients of three of the TRAT sub-tests used in this study, namely the assembly, spatial perception 2-D and 3-D sub-tests, range from 0.
The dexterity and coordination measures are speed tests and the K-R 21 formula is therefore not applicable Taljaard, With regards to the validity of the TRAT battery, the test manual indicates that no validity data were available at the time of printing. There is also a risk of restriction of range because of the potential lack of sensitivity of the instrument, which should be noted. However, the TRAT battery is a registered and approved psychological test by the Health Professions Council of South Africa and on this basis it was decided to continue using this instrument within the research study.
Research procedure and ethical considerations Data were collected over a period of several months. Following an in-house initial pre-screening process, candidates were required to participate in a multiple-hurdle selection process comprising two assessment phases.
Those successful in phase 1, the general aptitude tools, were requested to complete phase 2, the technical aptitude sub-tests. Answer sheets were manually scored using a scoring stencil, except for the dexterity and coordination measures, which were scored according to the psychological test manuals' scoring instructions.
In adherence to standard psychometric assessment practice, raw scores were converted to stanines, using the Grade 8 to Grade 10 norm table. Statistical analysis Statistical analysis of the data was conducted using the SPSS 20 statistical package. Descriptive and inferential statistics were calculated.
The descriptive statistics were intended to present a snapshot of the data, and the Chi-square test of independence was used to evaluate the relationship between secondary education incorporating subject choice and the five aptitudes assessed. In preparation for the execution of the inferential statistics, the aptitude sub-tests results were tabulated into three categories: The low-scoring category included stanine scores ranging from 1 to 3, the moderate category comprised the stanine scores 4 to 6, whilst the stanine scores 7 to 9 were designated to the high-scoring category.
Inferential statistics were then performed on these three scoring categories. In this study, the dependent variables were the five aptitudes assessed and the independent variable was the type of secondary education incorporating subject choice obtained. To test the significance of the relationship between the variables for the five hypotheses, the Chi-square test of independence was used.
An alpha level of 0. The null hypotheses were not rejected if there was independence between the variables, whilst the alternate hypotheses were acknowledged if there was covariation between the dependent and independent variables. In order to elucidate the magnitude of the relationship between the variables, effect size statistics were employed and interpreted.
Ethical consideration Permission was obtained from the automotive plant's head office to collect data in the organisation. All research respondents were also thoroughly informed of the assessment process and each participant voluntarily completed a specifically designed informed consent form.
Results Descriptive statistics Table 1 displays the descriptive statistics for the five aptitude sub-tests. The 2-D and 3-D spatial perception tools recorded the highest medians at seven, being in the high range.
The medians for the assembly and coordination sub-tests were within the moderate range, being six and five, respectively. The lowest median, three, was found for the dexterity measure. The highest mode, nine, was established for the spatial perception 2-D sub-test, with the second highest mode, being seven, recorded for the spatial perception 3-D instrument. The mode for the assembly sub-test was six, whilst a mode of five was documented for the coordination sub-test.
The mode for the dexterity sub-test was the lowest at three. Inferential statistics Chi-square tests of independence were completed to scrutinise the relationship between the form of secondary education incorporating subject choice and the stanine scores achieved in the five aptitude tests, grouped according to low, moderate and high scores. There is a significant relationship between levels of dexterity and type of secondary education qualification incorporating subject choice obtained.
The data provided in Table 2 show that the type of matriculation incorporating subject choice education obtained was significantly related to the dexterity sub-test scores. The p-value was 0.
Table 2 also illustrates that low stanine scores on the dexterity tool were associated with the technical and general Grade 12 qualifications. Hypothesis 1 was therefore accepted. There is a significant relationship between levels of coordination and type of secondary education qualification incorporating subject choice obtained.
The study's second null hypothesis stated that there would not be a significant relationship between levels of coordination and type of secondary education qualification incorporating subject choice obtained.
The significant correlation coefficient for this relationship was found to be The effect size 0. Seventy per cent of the respondents with mathematics and science as matric subjects and a general type of secondary education obtained moderate scores in this instrument. Hypothesis 2 was therefore accepted. There is a significant relationship between assembly scores and type of secondary education qualification incorporating subject choice obtained.
The relationship between these variables was characterised by a high, significant correlation coefficient of Stanine scores in the high category were associated with candidates who had obtained a matriculation education with either mathematics and science or just mathematics as subjects.
Ninety-eight per cent of the candidates with a Grade 12 qualification inclusive of science attained stanine scores of four and above for this tool. Hypothesis 3 was therefore accepted. There is a significant relationship between spatial perception 2-D and type of secondary education qualification incorporating subject choice obtained. Ninety per cent or more of the respondents with mathematics or mathematics and science or a technical Grade 12 qualification attained moderate- to high-level scores.
Hypothesis 4 was therefore accepted.
More than 75 percent decline over 27 years in total flying insect biomass in protected areas
There is a significant relationship between levels of spatial perception 3-D and type of secondary education incorporating subject choice qualification obtained. Table 6 provides the data supporting the relationship between the type of Grade 12 qualification incorporating subject choice and the spatial perception 3-D sub-test stanine scores. The effect size between the dependent and independent variables in this hypothesis was regarded as large and hence contextualises the importance of this hypothesis' findings Pallant, Just under half of the respondents with this type of matriculation also realised high stanine scores in this measure.
The technical and general types of matriculants were also associated with moderate to high stanine scores. Of the respondents with a general Grade 12 qualification, obtained stanine scores of four and above. Based on the results, Hypothesis 5 was therefore accepted. Discussion The primary objectives of this study were to investigate the relationship between hand-eye coordination test scores and types of secondary education incorporating subject choice and to determine whether the forms of secondary education incorporating subject choice were related to the spatial visualisation test scores.
Outline of the results Three conclusions have been derived from the study's five hypotheses. The first conclusion points to a differing complexity level across the five instruments employed in this study, whilst the second and third conclusions outline the different levels of aptitudes presented by matriculants with different types of secondary education. In Table 1which summarised the distribution of the five aptitude sub-tests, the increased intensity of exertion is clearly evident from the wide frequency distribution across the stanine scores of the five tools.
The median and mode for the dexterity measure, which assessed the respondents' two-hand-eye coordination, is significantly below those of the other four tools. The median and mode for the one-hand-eye coordination instrument was slightly higher than that obtained for the dexterity sub-test. The three measures of spatial visualisation realised central tendency stanine scores in the high-average to superior range. Thus, it is concluded that the respondents found the two psychomotor tools more challenging than the three spatial visualisation techniques.
Previous research has offered two explanations for this lower ability on high-speed aptitude tests. Firstly, because of outcomes-based education, SA students tend to be less speed oriented Van der Merwe, Secondly, the maintenance of selective attention in the youth has been radically reduced because of the continuous over-stimulation offered by readily available entertainment Cocodia et al.
The second conclusion pertains to the endorsed types of secondary education. Based on the results obtained across the five aptitude measures, three forms of secondary education incorporating subject choice are recommended, namely a Grade 12 qualification inclusive of science; a matriculation education with mathematics as a subject; and a secondary education including both mathematics and science subjects.
The applicants with the secondary education inclusive of science consistently outperformed the other applicants educated through matriculation type in three of the instruments, namely, dexterity, assemble and spatial perception 3-D. However, in two of the sub-tests, namely coordination and spatial perception 2-D, they were outperformed.
These three forms of secondary education are concluded to have been positively associated with the applicants' accomplishments in these specific aptitude measures. These forms of Grade 12 qualifications may also have afforded the applicants with exposure to a spatially enriched education as described in the research by Hsi et al.
This conclusion is in line with previous research which established that enhanced spatial ability is significantly associated with accomplishment in STEM domains Humphreys et al. Thirdly, the technical and general types of secondary education were not optimal performers in the five aptitude sub-tests. Whilst the technical matriculation applicants performed moderately well in the assembly and spatial perception 2-D sub-tests, they did not perform optimally in the other three sub-tests.
It is therefore concluded that these two forms of matriculation incorporating subject choice education are not able to reliably provide the technically oriented abilities required of automobile operators.
This confirms the abundance of literature indicating the educational crisis that is being experienced in the technical school system, both internationally and nationally. This study has emphasised the challenges faced by national FET institutions Department: Here, we investigate total aerial insect biomass between and across 96 unique location-year combinations in Germany, representative of Western European low-altitude nature protection areas embedded in a human-dominated landscape S1 Fig.
More than 75 percent decline over 27 years in total flying insect biomass in protected areas
In all years we sampled insects throughout the season March through Octoberbased on a standardized sampling scheme using Malaise traps. We investigated rate of decline in insect biomass, and examined how factors such as weather, habitat and land use variables influenced the declines.
Our study makes a first step into filling this gap, and provides information that is vital for the assessment of biodiversity conservation and ecosystem health in agricultural landscapes. Materials and methods Data Biomass data Biomass data were collected and archived using a standardized protocol across 63 unique locations between and resulting in 96 unique location-year combinations by the Entomological Society Krefeld.
The standardized protocol of collection has been originally designed with the idea of integrating quantitative aspects of insects in the status assessment of the protected areas, and to construct a long-term archive in order to preserve identified and not-identified specimens of local diversity for future studies.
In the present study, we consider the total biomass of flying insects to assess the state of local entomofauna as a group. All trap locations were situated in protected areas, but with varying protection status: For all location permits have been obtained by the relevant authorities, as listed in the S1 Appendix.
