Undergraduate Students’ Evaluation of Internships in Special Education Programs in Saudi Universities
This study aimed to identify the views of undergraduate students on internships in special education programs in Saudi universities and delineate any statistically significant differences in the students’ views attributable to gender, specialization, university, and grade point average. The study also attempted to investigate the extent to which education outcomes meet the labor market requirements of Saudi Arabia Vision 2030 from the perspective of internship students in special education programs in Saudi universities. To this end, a descriptive approach was applied, using a questionnaire to collect the study data. The study sample consisted of 271 internship students of special education in Saudi universities. The results revealed a high rating level for internships from the perspective of special education students. There were statistically significant differences in the ratings based on gender, with female students reporting better on the academic supervisor dimension. Students specializing in learning disabilities also shared better ratings than those in the autism program, and students with “Excellent” grades reported higher ratings of internship than those with “Good” grades. Overall, there was a high level of compatibility between educational outcomes and the requirements of the labor market stipulated by Vision 2030
4a-Methyl-2,3,4,4a-tetrahydro-1H-carbazole-6-sulfonamide
In the title molecule, C13H16N2O2S, the nine non-H atoms comprising the indole residue are approximately coplanar (r.m.s. deviation = 0.031 Å). The partially saturated ring adopts a chair conformation. One amine H forms an intermolecular N—H⋯O hydrogen bond to a sulfonamide O atom, while the other amine H form is connected to the indole N atom of an adjacent molecule via an N—H⋯N hydrogen bond, resulting in a three-dimensional architecture
2-Amino-4-phenyl-5,6-dihydrobenzo[h]quinoline-3-carbonitrile–3-amino-1-phenyl-9,10-dihydrophenanthrene-2,4-dicarbonitrile (5/3)
The asymmetric unit of the 5:3 title co-crystal of 2-amino-4-phenyl-5,6-dihydrobenzo[h]quinoline-3-carbonitrile and 3-amino-1-phenyl-9,10-dihydrophenanthrene-2,4-dicarbonitrile, 0.625C20H15N3.0.375C22H15N3, has the atoms of the fused-ring system and those of the amino, cyano and phenyl substitutents overlapped. The fused-ring system is buckled owing to the ethylene linkage in the central ring, the two flanking aromatic rings being twisted by 20.1 (1)°. This ethylene portion is disordered over two positions in a 1:1 ratio. The phenyl ring is twisted by 69.5 (1)° relative to the amino- and cyano-bearing aromatic ring. In the crystal, two molecules are linked by an N—H⋯N hydrogen bond, generating a a helical chain along [010]
3-Amino-1-(4-bromophenyl)-9,10-dihydrophenanthrene-2,4-dicarbonitrile
In the title compound, C22H14BrN3, the fused-ring system is buckled owing to the ethylene linkage in the central ring; the two flanking aromatic rings are twisted by 25.9 (1) ° with respect to each other. The phenyl ring is twisted by 77.0 (1)° relative to the amino- and cyano-bearing aromatic ring. In the crystal, adjacent molecules are linked by two N–H⋯N hydrogen bonds, generating a zigzag chain along [101]
3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carbaldehyde
In the title molecule, C12H12N2O, the five- and six-membered rings form a dihedral angle of 68.41 (16)°. The aldehyde group is nearly coplanar with the pyrazole ring [C—C—C—O torsion angle = −0.4 (5)°]. The three-dimensional architecture is sustained by weak C—H⋯O and C—H⋯π interactions
3-Amino-1-(thiophen-2-yl)-9,10-dihydrophenanthrene-2,4-dicarbonitrile
In the title compound, C20H13N3S, the partially saturated ring adopts a twisted half-boat conformation with the methylene C atom closest to the aminobenzene ring lying 0.690 (6) Å out of the plane defined by the five remaining atoms. The dihydrophenanthrene residue has a folded conformation [dihedral angle between the outer benzene rings = 26.27 (18)°]. The thiophen-2-yl ring forms a dihedral angle of 63.76 (19)° with the benzene ring to which it is attached. In the crystal, inversion dimers linked by pairs of N—H⋯N hydrogen bonds generate R
2
2(12) loops. The dimers are linked into layers in the bc plane by weak C—H⋯π interactions. The thiophen-2-yl ring is disordered over two essentially coplanar but opposite orientations in a 0.918 (4):0.082 (4) ratio
(2E)-2-[(2H-1,3-Benzodioxol-5-yl)methylidene]-2,3-dihydro-1H-inden-1-one
In the title compound, C17H12O3, each of the five-membered rings in the inden-1-one and 1,3-benzodioxole residues is almost planar (r.m.s. deviations = 0.041 and 0.033 Å, respectively). A small twist about the single bond linking the two residues is evident [the C—C—C—C torsion angle = 8.7 (4)°]. Supramolecular zigzag layers propagating in the ac plane are formed in the crystal via C—H⋯O interactions. The layers are linked via π–π interactions between the five- and six-membered rings of 1,3-benzodioxole residues [centroid–centroid distance = 3.4977 (14) Å]
