Sharing stories has become increasingly popular as a means to foster young children’s vocabulary development and to target early vocabulary gaps between disadvantaged children and their better-equipped peers. Although, in general, the beneficial effects of story interventions have been demonstrated (Marulis & Neuman, 2010, 2013), many factors possibly moderating those effects – including method of story delivery as well as questioning style – merit further examination (R. L. Walsh & Hodge, 2018).
The aim of the present doctoral thesis was to test predictions from different theories on methods of story delivery and questioning styles regarding their influence on children’s vocabulary learning from listening to stories. Method of story delivery refers to the general way of how stories can be conveyed, with reading aloud and free-telling of stories (i.e., the narrator telling stories without reading from text) representing different approaches that are assumed to differ regarding narrator behavior and linguistic complexity. Questioning styles refer to different combinations of questions’ cognitive demand level (low vs. high vs. scaffolding-like increasing from low to high) and/or placement (within the story vs. after the story) during story sessions.
In the present doctoral thesis, the first two studies (Studies 1 and 2) compared reading aloud and free-telling of stories as different methods of story delivery. Study 1 consisted of two experiments utilizing a within-subjects design with 3- to 6-year-old preschool children (Nexperiment1 = 83; Nexperiment2 = 48) listening to stories once either presented read aloud or freely told. Study 2 extended the first study by examining effects on story comprehension and additionally including audiotape versions of both story-delivery methods as experimental conditions, which allowed separating narrator behavior and linguistic complexity. With the second study being conducted as a between-subjects design, 4- to 6-year-old preschool children (N = 60) heard each of the stories twice, but listened only to one type of story delivery. The results of Study 1 indicated that no differences between methods of story delivery regarding word learning and child engagement were observable when narrator behavior in terms of eye contact and gesticulation was similar. However in Study 2, when free-telling was operationalized in a more naturalistic way, marked by higher rates of eye contact and gesticulation, it resulted in better child engagement, greater vocabulary learning, and better story comprehension than reading aloud. In contrast, as indicated by both studies, differences in linguistic complexity had no short-term impact on learning and comprehension. The studies, however, could not isolate the influence of eye contact versus gesture usage and could not distinguish between different types of gestures.
The second set of studies (Studies 3 and 4) contrasted the effects of different types of question demand level (low vs. high vs. scaffolding-like increasing from low to high) and placement (within the story vs. after the story) and examined potential interactions with children’s cognitive skills. In one-to-one reading sessions (Study 3; N = 86) or small-group reading sessions (Study 4; N = 91) 4- to 6-year-old preschool children heard stories three times marked by different types of question demand level and placement or simply read-aloud without questions. The adult narrators encouraged the children to reflect on and answer questions (Study 1) and to give feedback on other children’s comments (Study 2), but in both studies, to ensure fidelity of the experimental conditions, the adult narrators did not provide corrective feedback or elaborate on the children’s answers. Results on measures of different facets of word learning indicated that asking questions resulted in better vocabulary learning than simply reading the stories aloud. However, in contrast to proposed hypotheses and across both studies, different types of question demand level and placement did not exert differential effects and they did not interact with children’s general vocabulary knowledge or memory skills. Thus, both studies suggest that those two types of questions features have no impact on children’s vocabulary learning, if questions are not followed up by narrator feedback and elaborations. However, whether different types of question placement and demand level produce differential learning gains through adult-child discussion following different questioning styles has still to be determined.
Taken together, the four studies of the present doctoral thesis underline the central role that adults play for successful story sessions with young children not only for engaging children in the story but also for extending and for correcting their utterances. Although the presented studies extend existing knowledge about methods of story delivery and questioning styles during story sessions, further research needs to examine the impact of questioning styles on word learning through subsequent adult-child discussion and to gain a better understanding of the role of nonverbal narrator behavior during story delivery.
This dissertation contributes to deepen our understanding of constructs that play a key role in individuals’ vocational career construction. In this regard, many previous studies have focused exclusively on a specific phase of an individual’s career. Yet, modern societies
require continuous investments in one’s career to adapt to changing Environments throughout the life span. Consequently, this dissertation takes a broad approach to capture a wide spectrum of career construction processes.
According to Super’s (1990) developmental stage framework, individuals have to manage vocational developmental tasks corresponding to each of the developmental life stages in order to be career mature across the life span. As the two stages exploration and
maintenance set the stage for individuals’ future career pathways, they are especially important in individuals’ vocational career construction. Therefore, both of them are addressed in this dissertation.
By answering open research questions relevant to career choice in early career stages and to career development in later career stages, this dissertation contributes to the overarching goal of shedding more light on constructs relevant to individuals’ vocational career construction processes across the life span. Beyond the results presented within each study’s horizon, this dissertation aimed at offering practical guidance to career counselors,
trainees, and training and development (T&D) professionals. Career counselors and T&D professionals are involved in guiding vocational career construction processes of individuals across the life span. Thus, on the one hand, this dissertation supports career counselors’ work so that they can help deliberating individuals make optimal and effective career choices. On
the other hand, this dissertation facilitates T&D professionals’ work so that they can effectively design and evaluate e‐learning and classroom trainings in corporate educational settings. Identifying individuals’ vocational interests combined with cognitive abilities through adequate test measures and maximizing success of learning and success of transfer through fostering evidence‐based transfer support actions will help individuals adapt quickly to the changing nature of work environments in the 21st century and to continue to successfully construct careers across the life span.
This dissertation focuses on the construct and criterion validity of integrity tests and aims to enhance both. To accomplish this goal, three approaches were adopted: First, an overview and systematic comparison of integrity tests was conducted with reference to the construction and application of the tests. Second, the nomological network of integrity tests was expanded with reference to honesty-humility and organizational citizenship behavior at their factor and facet level. Third, two promising methods to reduce faking on integrity tests were tested: the double rating method (Hui, 2001) and the indirect questioning technique. In line with previous research, the results of the overview and comparison of integrity measures confirmed that integrity tests are multidimensional and heterogenous. A clear definition of integrity is urgently needed. The personality trait of honesty-humility and its facets of fairness, and modesty revealed the most significant relationships to integrity. Moreover, organizational citizenship behavior and its facets of altruism, conscientiousness, and sportsmanship were found to significantly relate to integrity. Furthermore, integrity tests were able not only to predict organizational citizenship behavior but also to incrementally predict job performance and organizational citizenship behavior beyond the factor and facet level of the personality traits of conscientiousness and honesty-humility. In contrast to the indirect questioning technique, the double rating method, which includes an other rating and a self rating, was shown to be able to significantly reduce faking on integrity tests in an anonymous survey setting. This dissertation makes an important contribution to better explain the construct and nomological network of integrity, provide a more detailed view on integrity tests and their protection against faking, and expand the predictive and incremental validity of these tests. The implications for future research and practice are further discussed.
The field of giftedness and gifted education has long been characterized by internal fragmentation and inconsistent definitions of core concepts (e.g., Ambrose et al., 2010; Coleman, 2006; McBee et al., 2012). It was only in recent years that increased efforts have been made to organize available research findings and thereby bring back greater uniformity to the field of giftedness and gifted education. For example, Preckel et al.’s (2020) Talent Development in Achievement Domains (TAD) framework integrates theoretical perspectives and empirical knowledge from different parts of the field. It is general in concept and can be applied to a wide range of achievement domains. By specifically focusing on measurable psychological constructs as well as their relevance at different stages of the talent development process, Preckel et al.’s (2020) TAD framework is well suited as a starting point for generating more domain-specific talent development models.
The present thesis represents one of the first attempts to empirically test the validity of Preckel et al.’s (2020) TAD framework in academic domains using longitudinal data. The longitudinal data came from a sample of former junior students at Julius-Maximilians-Universität (JMU) Würzburg who showed high academic achievement potential.
There were two related research issues: Research Issue 1 first aimed to document in detail how the educational trajectories of former junior students unfold in the years following their Abitur. To this end, a follow-up was conducted among 208 young adults who had participated in the junior study program at JMU Würzburg between the winter semester of 2004/2005 and the summer semester of 2011. The design of the follow-up questionnaire was based on a series of research questions that had emerged from the relevant literature on junior study programs in Germany. The follow-up ran from October 2019 to February 2020. The data were analyzed descriptively and documented as a detailed report. The results of Research Issue 1 revealed that the former junior students continued to be academically (and later professionally) successful long after their school years. For example, at the time of the follow-up, almost all former junior students had earned a bachelor’s and a master’s degree, most often with notable academic successes (e.g., scholarships, awards/prizes). In addition, more than half of those who responded had begun or already completed a doctoral degree, also recording special academic accomplishments (e.g., scientific publications, scholarships). A significant proportion of the former junior students had already entered the workforce at the time of their response. A look at their current professional situation revealed an above-average expression of success indicators (e.g., income, professional status). The clear majority of the former junior students reported that, even in retrospect, they would choose to take part in the junior study program at JMU Würzburg again.
Research Issue 2 aimed to determine the extent to which the structure of Preckel et al.’s (2020) TAD framework could be empirically validated in academic domains. The educational trajectories of 84 former junior students at JMU Würzburg who had chosen a subject from the same subject field in their regular studies as in their junior studies served as the data basis. The educational trajectories were compiled from the former junior students’ follow-up data and from their data on the selection process for the junior study program at JMU Würzburg. Combining the structural assumptions of Preckel et al.’s (2020) TAD framework with relevant insights from individual academic disciplines made it possible to derive hypotheses regarding potential predictors and indicators of the talent development stages aptitude, competence, and expertise in academic domains. Structural equation models were used for data analysis. The results of Research Issue 2 suggested that the talent development stages aptitude, competence, and expertise, while being predictive of each other in their chronological order, could be satisfactorily modeled using framework-compliant indicators in academic domains. In comparison, the talent development stage transformational achievement could not (yet) be modeled based on the longitudinal data. Among the hypothesized predictors, former junior students’ investigative interests and their metacognitive abilities reliably determined the talent development stages competence and expertise, whereas the remaining predictors did not make significant contributions.
Taken together, the results of the present thesis suggest that the validity of Preckel et al.’s (2020) TAD framework can only be partially confirmed in academic domains. Unlike the postulated indicators, the predictors in Preckel et al.’s (2020) TAD framework do not seem to be easily generalizable to academic domains but to be highly specific with regard to the talent domain under consideration. Therefore, a natural progression of the present thesis would be to examine the structure of Preckel et al.’s (2020) TAD framework at the subordinate level of subject fields or even at the level of individual academic disciplines, for example.
