It is well-documented that cyberbullying and victimization co-occur with traditional forms indicating that they share similar mechanisms. Therefore, it was hypothesized that the general antibullying program ViSC might also be effective in tackling these new forms of bullying. A longitudinal randomized control group design has been applied to examine the program effectiveness in 18 schools. In total, 2,042 students in Grades 5 to 7 (47.3% girls) aged 11.7 (SD = 0.9) attending 105 classes participated in the study. Utilizing a multiple group bivariate latent change score model controlling for traditional aggression, traditional victimization, and age, results demonstrate program effectiveness for cyberbullying (latent d = 0.39) and cyber victimization (latent d = 0.29) indicating that these behaviors reflect a systemic (school) problem.

The term ‘Plant Blindness’ describes people tending to overlook plants, even though they have an enormous importance for life on earth, especially because of their ability to photosynthesise. Many attempts have been made to counteract plant blindness in biology education. However, so far there is no comprehensive tool to assess the degree of plant awareness (instead of plant blindness) in students. Here, plant awareness is conceptualised in four domains: (1) visual perception of plants, (2) categorising plants as living organisms, (3) knowledge about plants, and (4) attitudes towards plants. We present results from the two developed scales ‘Plants as living organisms’ and ‘Knowledge about plants’. To test the new scales, 345 Austrian secondary school students took part in a questionnaire study. A confirmatory factor analysis indicates sufficient model fit. Results show that students consider plants as ‘less alive’ than animals but ‘more alive’ than bacteria. Those who attribute the characteristics of life to plants have more knowledge about plants, indicating that both domains of plant awareness might have a common basis. The development of a plant awareness questionnaire will eventually provide a powerful tool to investigate the effectiveness of learning environments fostering plant awareness, a prerequisite to reach the sustainable development goals.

Understanding the structure, antecedents, and outcomes of students’ emotions has become a topic of major interest in research on mathematics education. Much of this work is based on the Achievement Emotions Questionnaire—Mathematics (AEQ-M), a self-report instrument assessing students’ mathematics-related emotions. The AEQ-M measures seven emotions (enjoyment, pride, anger, anxiety, shame, hopelessness, boredom) across class, learning, and test contexts (internal structure). Based on control-value theory, it is assumed that these emotions are evoked by control and value appraisals, and that they influence students’ motivation, learning strategies, and performance (external relations). Despite the popularity and frequent use of the AEQ-M, the research leading to its development has never been published, creating uncertainty about the validity of the proposed internal structure and external relations. We close this gap in Study 1 (N = 781 students, Grades 5–10, mean age 14.1 years, 53.5% female) by demonstrating that emotions are organized across contexts and linked to their proposed antecedents and outcomes. Study 2 (N = 699 students, Grade 7 and 9, mean age 14.0 years, 56.9% female) addresses another deficit in research on the AEQ-M, the lack of evidence regarding the assumption that emotions represent sets of interrelated affective, cognitive, motivational, and physiological/expressive components. We close this gap by evaluating extended AEQ-M scales, systematically assessing these components for five core mathematics emotions (enjoyment, anger, anxiety, hopelessness, boredom). Our work provides solid grounds for future research using the AEQ-M to assess emotions and their components in the domain of mathematics.

The effectiveness of a class-based antibullying prevention program on cognitions, emotions, and behaviors was investigated. The program consists of a cognitive-behavioral (Rational Emotive Behavioral Education; REBE) and a behavioral (Viennese Social Competence; ViSC) component. The REBE program is based on rational emotive behavioral theory and contains 9 student lessons. The ViSC program is based on social learning theory and comprises 10 student lessons. The order of the programs was experimentally manipulated. The REBE-ViSC program was implemented in 5 schools (14 classes), the ViSC-REBE program was implemented in 3 schools (9 classes), and 3 schools (11 classes) served as an untreated control group. Data were collected during 1 school year at pretest, midpoint, and posttest. Emotions (overt and internalizing anger), cognitions (learning and entitlement), and behaviors (bullying perpetration and bullying victimization) were measured with self-assessments. To examine the effectiveness of the REBE-ViSC/ViSC-REBE program, multilevel growth models were applied (time points at Level 1, individuals at Level 2, and classes at Level 3). The analyses revealed that the program effects differed depending on the order of the programs. The REBE-ViSC condition was more effective in changing negative emotions than the ViSC-REBE condition; both experimental conditions were effective in reducing dysfunctional cognitions, whereas no behavioral change was found in the 2 experimental groups when compared with the control group. To improve program effectiveness regarding behavioral changes, a multilevel whole-school approach including a teacher component is recommended.

The present study reports a high-quality evaluation of the ViSC Social Competence Program, which was implemented large scale in Austria. A rigorous test of program effectiveness has been performed to investigate the dynamic change of aggressive behavior and victimization and to ensure a high level of statistical conclusion validity. A cluster randomized control study was applied to examine program effectiveness regarding aggressive behavior and victimization. In sum, 1,377 adolescents (48.5% girls, Mage = 11.7) enrolled in 13 schools participated in the program; 665 adolescents (45.2% girls, Mage = 11.6) enrolled in 5 schools were in the control group. Data were collected with Internet-based questionnaires at pre- and posttest with several validated scales to capture the full range of the two constructs. To ensure construct validity, a series of invariance tests of the second-order factor models were performed. To test program effectiveness, a multiple group bivariate latent change score model was applied. Evidence for a dynamic change of aggressive behavior and victimization was found. As predicted, the pretest levels and the change scores of aggressive behavior and victimization were associated. Moreover, higher levels of pretest values predicted more change. The program was effective in reducing victimization but not aggressive behavior. Gender did not moderate the results. Results are important for national rollout and cross-national dissemination of the program. However, further research is needed to investigate the underlying mechanisms of the intervention effects.
