The equivalence of learning paths in early science instruction: Effects of direct instruction and discovery learning.
It is concluded that the placebo caffeine research paradigm is not suitable for researching instruction effects in Germany, and that reported effects should be reproduced with tighter controls.
More than 1000 different instructions compose the scenarios that vary the processing unit rate, that is to account for the inter-instructions effect.
A 2 (Group) × 3 (Instruction) ANOVA for mean square root transformed VPA difference scores yielded a marginally significant main effect for Instruction, F 2, 66) = 2.48, p = .092, d = 0.54.
The P300 was enhanced to the infrequent stimuli, but there was no main effect for target instruction, although instruction did impact a higher-order interaction.
A main effect for Instruction was found, F 2, 65) = 5.27, p < .01, d = 0.80, indicating that, in line with predictions, women who received the genital pain instruction reported highest levels of negative affect, whereas women who received the sexual enjoyment instruction reported lowest levels of negative affect.
For example, if we measured student achievement in two courses with different instructional approaches in a typical pretest/posttest design, then the interaction between students' pretest scores and the type of instruction must be considered, because the instruction may have a different effect for high- versus low-achieving students.
The exploratory analyses with the SNAP ODD score as covariate did not yield significant effects for ODD: in the repeated measures MANCOVA (group by Reward by Instruction) neither a significant main effect for ODD (p =.224), nor interaction effects of Reward by ODD (p =.553) or Instruction by ODD (p =.544) emerged.
Now that the within-subjects effects have been explored, the main effect for between-subjects variable (type of instruction: 'focus on form' instruction versus 'focus on forms' instruction) needs to be considered.
A marginally significant group by instruction interaction effect was observed for positive affect, indicating that women with dyspareunia reported significantly less positive affect than controls after the sexual enjoyment instruction (d = 1.48).
For all medication groups a protocol is developed that describes the specific instructions or side effects for that specific group.
