Cognitive Diagnosis for Small Educational Programs: The General Nonparametric Classification Method

The focus of cognitive diagnosis (CD) is on evaluating an examinee’s strengths and weaknesses in terms of cognitive skills learned and skills that need study. Current methods for fitting CD models (CDMs) work well for large-scale assessments, where the data of hundreds or thousands of examinees are available. However, the development of CD-based assessment tools that can be used in small-scale test settings, say, for monitoring the instruction and learning process at the classroom level has not kept up with the rapid pace at which research and development proceeded for large-scale assessments. The main reason is that the sample sizes of the small-scale test settings are simply too small to guarantee the reliable estimation of item parameters and examinees’ proficiency class membership. In this article, a general nonparametric classification (GNPC) method that allows for assigning examinees to the correct proficiency classes with a high rate when sample sizes are at the classroom level is proposed as an extension of the nonparametric classification (NPC) method (Chiu and Douglas in J Classif 30:225–250, 2013). The proposed method remedies the shortcomings of the NPC method and can accommodate any CDM. The theoretical justification and the empirical studies are presented based on the saturated general CDMs, supporting the legitimacy of using the GNPC method with any CDM. The results from the simulation studies and real data analysis show that the GNPC method outperforms the general CDMs when samples are small.     

Strategies to Engage Underrepresented Parents in Child Intervention Services: A Review of Effectiveness and Co-occurring Use

The purpose of this review was to estimate the impact of parent engagement strategies tested with underrepresented families of young children with social, emotional, or behavioral disorders, and describe the combinations in which these strategies are commonly used together. We conducted a systematic review using the PracticeWise Engagement Coding System to identify which strategies had the strongest empirical support for engaging underrepresented (i.e., minority race or ethnicity, or low income) families receiving psychosocial services for their children. Social network analyses were used to identify the frequency of strategy use and how strategies were combined to engage underrepresented families. Linear regression was used to estimate the impact of each strategy on parent engagement, using attrition as a proxy for non-engagement. Thirty-five studies met inclusion criteria. Parent attrition was predicted by larger sample sizes, lower maternal education, interventions that were more community or home-based, less therapist monitoring, positive reinforcement from therapists, and more pairing families with peers. Social network analyses suggested that more effective strategies were more frequently implemented alone and less effective strategies were commonly combined with each other. Our findings suggest that researchers and practitioners require guidance in selecting engagement strategies to reduce attrition of underrepresented families in treatment. Although we identified promising strategies for improving parent engagement in treatment for underrepresented children with social, emotional, or behavioral disorders, the frequent combining of engagement strategies in research means that there is little data on the independent effects of interventions to increase parent engagement for this population.     

Blazing the trail versus trailing the group: Culture and perceptions of the leader’s position

Research suggests that power triggers assertive action. However, people from different cultures might expect different types of action from powerful individuals such as leaders. In comparing cultural differences in leadership imagery, we find that Americans represent leaders standing ahead of groups, whereas Asians also represent leaders behind groups. We propose that front versus back positions embody two faces of leader action: individual assertion versus group-focused action. Studies 1a and 1b respectively employed etic and emic methods to demonstrate that Singaporeans were more likely than Americans to represent leaders behind groups. In Study 2, Singaporeans evaluated back leaders more favorably than Americans did, and group focus mediated cultural differences. Simulating the conditions under which cultural differences arise, Study 3 demonstrates that a primarily Western managerial sample primed with threat (versus opportunity) preferred back leaders. By describing cultural variations in imagery, we reveal more nuanced implicit theories of leader action.     

Asians as the model minority: Implications for US Government's policies

Asian Americans are often perceived as a 'model minority'– an ethnic minority that are high achieving, hardworking, self-reliant, law-abiding, as well as having few social and mental health problems. Although the impact of the model minority image on the US government's redistributive policies is a widely contested topic in public discourses, there has been little research on the association between the model minority image, people's worldviews, and attitudes towards the US government's redistributive policies. In an experiment that measured American participants' worldviews and manipulated the salience of the model minority image, we have demonstrated that those who believed in a malleable social reality were relatively unsupportive of government policies that help the Asian American ( vs African American) communities. Theoretical and practical implications of this finding are discussed.     

Green Tea and Ham: Cultural Mixing Reminders Decrease Considerate Behavior

Past research examined how encounters with cultural mixing affect people’s responses toward those cultures. We examined broader effects of cultural mixing—on general social behavior. We tested that reminders of mixing between one’s local culture and a foreign culture make people less considerate. Also, this response is more likely for people who are voluntarily psychologically distant (vs. close) to the foreign culture. In studies with Americans, reminders of American and Asian (local–foreign) cultural mixing decreased considerate behavior. Individuals who were psychologically distant from Asian culture showed this effect (Studies 1–5). The underlying process involved perceived threat (Studies 2–5). Threat was decreased by highlighting cleansing (Study 3) or priming affinity to Asian culture (Study 5). Overall, mixing between home and foreign cultures can put people in a self-protective (self-concerned) mode that decreases their consideration of others. We discuss the implications for research on cultural mixing and organizational behavior.     

The relative importance of math‐ and music‐related cognitive and affective factors in predicting undergraduate music theory achievement

Based on research identifying relations between math and music, we aimed to identify the group of cognitive and affective factors related to math and music theory that best explained undergraduate music theory achievement. Using dominance analysis, we predicted the music theory course grades of 230 undergraduate music majors. Potential predictors were narrowed from measures of knowledge, aptitude, experience, confidence, and anxiety in both music theory and math as well as spatial skills and reading test scores. Results suggested that ACT math scores and music theory confidence were important predictors for Music Theories I and II grades. Music Theory I was also predicted by aptitude‐based music theory skills, and Music Theory II was also predicted by math course experience. These findings provide evidence for a relation between math and music theory and support the use of several readily available measures for college‐level music instructors to identify students who may struggle in music theory.     

Biases in the perceived prevalence and motives of severe acute respiratory syndrome prevention behaviors among Chinese high school students in Hong Kong

In two studies conducted in Hong Kong during and immediately after the outbreak of severe acute respiratory syndrome (SARS), participants displayed several social cognitive biases when they estimated the prevalence of and inferred the motives underlying SARS preventive behaviors. First, participants who practiced preventive behaviors (practicers) consistently estimated that more people practiced such behaviors than did non-practicers (false consensus bias). Second, for some preventive behaviors, participants believed that their own behaviors were more motivated by prosocial concerns (relative to self-interest) than were other practicers (pluralistic ignorance). Finally, non-practicers underestimated the importance of prosocial concerns underlying some preventive behaviors (actor-observer bias). We discussed the relevance of these social cognitive biases to health education and to Hong Kong people's psychological reactions to SARS.
