Teachers' pedagogical content knowledge (PCK) is highly important for effective design and implementation of school teaching. Thus, the current status, development and efficacy of this knowledge, its relationships with teaching quality parameters, and its impact on students' learning processes and success, require rigorous examination. Thoroughly validated, objective and reliable test instruments that are highly sensitive to changes in variables of proven knowledge-related relevance in teacher education are also required. Previous attempts to design such instruments for assessing science teachers' PCK have largely focused on mathematical content. Therefore, here we present an instrument (the pedagogical content knowledge in biology inventory, PCK-IBI), based on conceptualizations of teachers' professional competence, for assessing secondary school preservice biology teachers' PCK. In a series of three evaluations and refinements it was tested with samples of N = 274 and N = 432 German pre-service as well as one sample of n = 65 German pre-service and n = 35 German in-service biology teachers. Item analysis, scale analysis and empirically obtained indicators of validity suggest that the final 34-item-version of the PCK-IBI is unidimensional, provides objective test scores and enables reliable and valid registration of pre-service biology teachers' PCK. Thus, hypotheses regarding specific aspects of the model on which the PCK-IBI's construction is based on are empirically supported. The results of our study provide empirical support for the instrument's potential utility.

Concept Mapping (CM) is a learning strategy to organize and understand complex relationships, which are particularly characteristic of the natural science subjects. Previous research has already shown that constructing concept maps can promote students’ meaningful learning in terms of deeper knowledge and its more flexible use. While researchers generally agree that students need to practice using CM successfully for learning, key parameters of effective CM training (e.g., content, structure, and duration) remain controversial. This desideratum is taken up by our study, in which three different training approaches were evaluated: a CM training with scaffolding and feedback vs. a CM training without additional elements vs. a non-CM control training. In a quasi-experimental design, we assessed the learning outcome of N = 73 university students who each had participated in one of the trainings before. Our results suggest that an extensive CM training with scaffolding and feedback is most appropriate to promote both CM competence and acquisition of knowledge. From an educational perspective, it would therefore be advisable to accept the time-consuming process of intensive practice of CM in order to enable students to adequately use of the strategy and thus facilitate meaningful learning in terms of achieving sustained learning success.

The Conceptual Model Map (CMM) presented here is intended to show the connections between different theories and constructs in the field of health and nutrition behavior (including literacy models, the knowledge–attitude(s)–practice(s) survey structure (KAP), behavior change theories, and Maslow’s pyramid of needs). The CMM can be used as a map to locate existing and future studies, to show their range of effect as well as their limitations. In this context, the CMM also reveals reasons for the attitude/intention–behavior gap.

Despite the need for enduring preventive behavior in times of the COVID-19 pandemic, several counteracting behavioral reactions can be observed worldwide. Considering the grave consequences resulting from such health-related risk behavior, we carried out an online questionnaire study to identify personal characteristics that frame a motivational sketch of those who refuse to follow the pandemic-related preventive measures. Our results from a sample of N = 570 German participants already indicate obvious changes in relevant variables in the four-week investigation period during the pandemic’s initial phase (25 March to 22 April 2020). Above all, the willingness to take preventive measures decreased, as did the assessment of the pandemic’s severity. The perceived own vulnerability also turned out to be clearly age-dependent and, overall, our sample showed a negative affectivity deviating distinctively from a reference sample. These and other findings allow for identification of sources for public health interventions that can help to increase compliance with required prevention behavior, and thus, counteract COVID-19.

BACKGROUND: Food literacy, a sub-area of health literacy, is achieving attention in schools, academia, research, health care, businesses, and governments worldwide. Against the current COVID-19 pandemic backdrop, the relevance of food literacy's interconnected attributes such as nutritional knowledge, food skills, and food environment is gaining traction. Enhancing health and food literacy in the K-12 school environment are important empowerment tools with the potential to reduce health inequalities as vulnerable people are at risk of limited health literacy. METHODS:We aim to clarify the meaning of food literacy and its relationship to health literacy and other factors influencing eating behavior. RESULTS:We offer a proposed conceptual model depicting connections between relevant theories and constructs in the field of health and nutrition. Concrete actions are offered that contemporary schools can take guided by the utility of the model. CONCLUSIONS:This visual can help guide schools' multidimensional health and food literacy efforts while considering the realities of the current COVID-19 pandemic context and beyond. This model will provide an overarching reference for schools to consider key constructs to support practice, research, policy, and intervention efforts to advance their health and food literacy agendas.
