A quasi-experimental design was used to investigate aptitude-treatment interaction in conditions of high instructional support (Personalized System of Instruction) and low instructional support (Lecture). A test for the homogeneity of regression coefficients indicated a significant (p <. 01) prior mathematics preparation x level of instructional support interaction. The most dramatic differences in post-course achievement favoring the high instructional support condition accrued to those students at the relatively lowest levels of prior mathematics preparation. Moreover, as level of prior mathematics preparation increased, the achievement differences between levels of instructional support tended to decrease. A verification analysis conducted on a separate sample yielded essentially the same interactive effect.

Mathematics Self Efficacy

This study aims to determine differences in mathematics self-efficacy among students who learn to use the Aptitude Treatment Interaction (ATI) approach with students receiving conventional learning. This study is a quasi-experimental research, where teachers who play a direct role in the learning process and there researcher as an observer. Subjects in this study were 32 students on grade VIII SMP Negeri 2 Bangkinang Pekanbaru. Data collected by aptitude tests, observation, test result, and questionnaire. The result of this experiment indicated that self-efficacy scores students who learn using ATI approach and students receive conventional learning are different.

Selected results from an ATI (aptitude × treatment interaction) study are presented in support of the importance of including class analyses in ATI research. This study investigated the interactive effects on performance and motivation of four motivational aptitudes and two cognitive aptitudes with a choice versus no-choice treatment manipulation. Both treatments were implemented in each of nine fourth- or fifth-grade classrooms (n = 165) over a 4-week period. Three sets of simple regression results (by treatment, within class, and between class) highlighted the differential effects of treatment on individuals versus classes and suggested substantive hypotheses about these effects.

Summary: This article describes a triarchic analysis of an aptitude-treatment interaction in a college-level introductory-psychology course given to selected high-school students. Of the 326 total participants, 199 were selected to be high in analytical, creative, or practical abilities, or in all three abilities, or in none of the three abilities. The selected students were placed in a course that either well matched or did not match their pattern of analytical, creative, and practical abilities. All students were assessed for memory, analytical, creative, and practical achievement. The data showed an aptitude-treatment interaction between students' varied ability patterns and the match or mismatch of these abilities to the different instructional groups.

This research constitute my research experiment attention. Subjec in observational it is student braze VIII4 as agglomerate as experiment by totals student 40 person and VIII3'S classes as agglomerate as controls by totals students 40. Base analisis data to pretes's score to know student startup ability on agglomerate experiment and control group. On student experiment group that will study by ATI'S approaching has average early learned result mathematics (pretes) as big as 17,15. Meanwhile on group controls student who will study by ordinary learning (conventional) have average early learned result mathematics (pretes) as big as 13,85. Analisis is data to postes's score on agglomerate learned student experiment with ATI'S approaching has average final learned result mathematics (postes) as big as 74,63. Meanwhile on group controls learned student with ordinary learning (conventional) have average final learned result mathematics (postes) as big as 62,93.

Toxic Compound

The effects of three common agrochemicals, lindane, methyl parathion and atrazine, on crustacean Daphnia magna, alga Selenastrum capricornutum and marine bacterium Vibrio fischeri were investigated in this study. Methyl parathion was the most toxic compound towards all three organisms, while lindane was more toxic to Daphnia magna and Vibrio fischeri than atrazine, and atrazine was more toxic to Selenastrum capricornutum than lindane. Among the three aquatic organisms, Selenastrum capricornutum was most sensitive in detecting lindane and atrazine toxicity, while Daphnia magna was most sensitive in detecting methyl parathion toxicity. The interactive effects of the pesticides were also investigated. The interactive effect between lindane and methyl parathion on survival of Daphnia magna was synergistic, while the ones between lindane and atrazine and between methyl parathion and atrazine were generally additive. The interactive effect of the three pesticides applied together on Daphnia magna was synergistic. The interactive effect of the three pesticides on the growth of Selenastrum capricornutum was antagonistic with few cases of addition, while the effect of all the three pairs of pesticides on algal growth was also antagonistic. The interactive effect of lindane and methyl parathion on Vibrio fischeri was additive.

Purpose This paper proposes that categorization flexibility, operationalized as the cognitive capacity that cross-categorizes products in multiple situational categories across multiple domains, might favorably influence a consumer’s evaluation of unconventional options. Design/methodology/approach Experimental research design is used to test the theory. An exploratory study first establishes the effect of categorization flexibility in a non-food domain. Study 1 documents the moderating role of decision domain, showing that the effect works only under low- (vs high-) consequence domain. Studies 2A and 2B further refine the notion by showing that individuals can be primed in a relatively higher categorization flexibility frame of mind. Study 3 demonstrates the interactive effect of categorization flexibility and adventure priming in a high-consequence domain. Study 4 integrates the interactive effects of decisions with low- vs high-consequence, adventure priming and categorization flexibility within a single decision domain of high consequence. Findings Consumers with higher- (vs lower-) categorization flexibility tend to opt for unconventional choices when the decision domain entails low consequences, whereas such a result does not hold under decision domain of high consequences. The categorization flexibility effects in case of low-consequence decision domain holds true even when consumers are primed to be categorization flexible. Furthermore, with additional adventure priming, consumers show an increased preference for unconventional options even under a decision domain with high consequence. Research limitations/implications This study could not examine real purchase behavior as results are based on cross-sectional, behavioral intention data. In addition, it did not examine the underlying reason for presence of cross-domain categorization flexibility index. Practical implications The results suggest that stimuli may be tailored to consumers in ways that increase the salience and the perceived attractiveness of unconventional choices. Further, data reinforce the notion of cross-categorical interrelations among different domains, which could be leveraged by marketers. Originality/value This study represents the first documentation of the potential ways by which unconventional product choice might be a function of individuals’ categorization flexibility level across different types of decision domains. The findings yield implications that are novel to both categorization and consumer decision-making literature.
