The four treatment conditions were as follows: 1) inquiry instruction with homogeneous collaborative groups, 2) inquiry instruction with heterogeneous collaborative groups, 3) didactic instruction with homogeneous collaborative groups, and 4) didactic instruction with heterogeneous collaborative groups (see Table 1).
Apoptosis was confirmed by elevated capase-3/7 activity[ 39], determined using a commercially available kit according to manufacturer's instructions (Apo-ONE Homogeneous Caspase-3/7 Assay, Promega).
Caspase-3/-7 activity was measured at 90 min by a fluorescence plate reader (FLUOstar Galaxy, Isogen Life Science, Maarssen, The Netherlands) as per the manufacturer's instructions (Apo-ONE™ homogeneous caspase-3/-7 assay, Promega UK Ltd., Southampton, UK).
The assay was performed according to the manufacturer's instructions (Apo-ONE Homogeneous Caspase 3/7 Assay, Promega) and the release of the fluorogenic moiety by activated caspases was measured by reading plates at 405 nm using a fluorometric plate reader.
Further, inquiry sections had higher scores on reasoning transfer items, with significantly higher performance within homogeneous groups, showing that inquiry instruction improves reasoning skills more effectively than noninquiry instruction.
The Wenzel and Cassie-Baxter models, which correspond to the homogeneous and heterogeneous wetting respectively, are currently primary instructions for designing superhydrophobic surfaces.
Apoptosis was detected by measuring enzyme activity of caspase 3/7 using the Apo-One® Homogeneous Caspase 3/7 Assay following the manufacturer's instructions (Promega Corporation, Madison, USA).
Capase-3/7 activity was measured after 4 days of culture using Apo-ONE Homogeneous Caspase-3/7 (Promega) according to the manufacturer's instructions.
The extent of apoptosis was assessed by measuring the activities of caspases 3 and 7 using the Apo-ONE Homogeneous Caspase-3/7 Assay, according to the manufacturer's instructions (Promega, Charbonnieres, France).
The central argument behind different school-types, tracking or ability grouping is that homogeneous learning environments permit a focused curriculum and paced instruction, which increases the average performance of all students (Hanushek and Wössmann, 2005).
