Using the Plan–Teach–Reflect Cycle of the Refined Consensus Model of PCK to Improve Pre-Service Biology Teachers’ Personal PCK as Well as Their Motivational Orientations

In this article, we analyse how to improve pre-service biology teachers’ pPCK (personal Pedagogical Content Knowledge), professional values and motivational orientations in the field of academic and scientific language. On the basis of the theory of the Refined Consensus Model of PCK (RCM), we made a two-month quasi-experimental intervention study with 32 pre-service biology teachers. As a treatment, we trained the participants in the Plan–Teach–Reflect Cycle of enacted PCK in a school class, in the framework of a seminar. In the control group, the teaching of the cycle was replaced by presentations of their lesson plans. As dependent variables, we analysed participants’ pPCK, professional values and motivational orientations. Our results showed an increase in pre-service biology teachers’ pPCK (F(1,28) = 3.51, p = 0.04, part. η2 = 0.11, d = 0.70) and motivational orientations (F(1,23) = 29.68, p < 0.01, part. η2 = 0.56, d = 2.26) in both groups, but no effects on participants’ professional values. The teaching experience in a school class strengthened the effects both in participants’ pPCK (F(1,28) = 2.92, p = 0.04, part. η2 = 0.10, d = 0.67) and motivational orientations (F(1,23) = 7.64, p < 0.01, part. η2 = 0.25, d = 1.15). We recommend integrating the use of the Plan–Teach–Reflect Cycle of ePCK into science teacher education programmes

The Refined Consensus Model of Pedagogical Content Knowledge (PCK): Detecting Filters Between the Realms of PCK

In this article, we analyse potential filters that moderate the transformation process between the realms of PCK defined in the refined consensus model of pedagogical content knowledge. We tested 58 preservice biology teachers in a 15-week one-group pretest/post-test design. To identify filters between collective PCK (cPCK) and personal PCK (pPCK), we set up moderation models with pretest pPCK as an independent variable, post-test pPCK as a dependent variable, and motivational orientations or professional values as moderator variables. To identify filters between pPCK and enacted PCK (ePCK), we set up moderation models with post-test pPCK as an independent variable, ePCK as a dependent variable, and noticing or knowledge-based reasoning as moderator variables. We did this specifically with a focus on language in biology education. We found that only the variable knowledge-based reasoning had a role as a filter. It moderates the transformation process between pPCK and ePCK (moderation analysis: F(3,19) = 10.40, p < 0.001, predicting 25.72% of the variance). In future studies, other filters should be identified

Integrating or Not-Integrating—That is the Question. Effects of Integrated Instruction on the Development of Pre-Service Biology Teachers’ Professional Knowledge

For successful classroom instruction, teachers require a well-founded knowledge base consisting of the three knowledge facets pedagogical-psychological knowledge (PK), content knowledge (CK), and pedagogical content knowledge (PCK). However, there is not yet clarity about the circumstances and instructional pathways through which teachers can best develop these knowledge facets. In an experimental study (N = 118 pre-service biology teachers), we investigated the effects of separated instruction (knowledge facets were treated successively without linking) or integrated instruction (knowledge facets were presented in an interrelated way) on PK, CK, PCK and the application of PCK in a video-based assessment tool in comparison to a control group (receiving no instruction). Both pathways of instruction were provided by a lecturer on the curricular topic of senses and sensory organs, exemplified for the topic skin. Results point to the effectiveness of both ways of instruction in terms of knowledge increases for CK and PCK. In addition, working with the video-based assessment tool may have had an additional effect on PCK. No effects for PK could be found, possibly due to a ceiling effect. Moreover, there was no effect of the intervention on the application of PCK. However, tendencies in descriptive results indicating a possible advantage concerning separated or integrated instruction with regard to CK and PCK are discussed. Overall, our results indicate that the use of video-based tools can complement instructional approaches to knowledge acquisition

Learning to diagnose secondary school students' scientific reasoning skills in physics and biology: video-based simulations for pre-service teachers

Since the ability to teach and therefore also diagnose not only subject-specific but also cross-domain skills are an important part of every teacher’s day-to-day work, we developed simulations to quantify and furthermore support the competence to diagnose secondary school students’ scientific reasoning skills. For this purpose, the simulations also include the possibility to rehearse interdisciplinary collaborations between physics and biology pre-service teachers. The simulations are video-based, containing short, scripted videos showing two students working on different inquiry tasks, including a physics and a biology experiment. Participants have to observe the students and can individually decide which pre-formulated questions they want to ask the students before, during and after the experiments to gather relevant information. The corresponding simulated answers are subsequently presented via additional videos. The information gained during the simulations is supposed to be used to diagnose the students’ scientific reasoning skills later in the process

Scientific Reasoning in Biology – the Impact of Domain-General and Domain-Specific Concepts on Children’s Observation Competency

Research on the development of scientific reasoning has put the main focus on children's experimentation skills, in particular on the control-of-variables strategy. However, there are more scientific methods than just experimentation. Observation is defined as an independent scientific method that includes not only the description of what is observed, but also all phases of the scientific inquiry, such as questioning, hypothesizing, testing, and interpreting. Previous research has shown that the quality of observations depends on specific knowledge in the domain. We argue that observation competency shares the domain-general ability to differentiate hypotheses from evidence with other scientific methods. The present study investigates the relations of both domain-general scientific thinking and domain-specific knowledge in biology with observation competency in grade K children. We tested relations between observation competency, domain-general scientific reasoning, domain-specific knowledge, and language abilities of 75 children (age 4;9 to 6;7). Both scientific reasoning and domain-specific knowledge proved to be significant predictors of observation competency, explaining 35% of the variance. In a mediation analysis, we found a significant indirect effect of language via these two predictors. Thus, the present results indicate that observation skills require not only domain-specific knowledge but also domain-general scientific reasoning abilities

The diagnosis of scientific reasoning skills: how teachers' professional knowledge predicts their diagnostic accuracy

Diagnostic competences of teachers are an essential prerequisite for the individual support of students and, therefore, highly important. There is a substantial amount of research on teachers’ diagnostic competences, mostly operationalized as diagnostic accuracy, and on how diagnostic competences may be influenced by teachers’ professional knowledge base. While this line of research already includes studies on the influence of teachers’ content knowledge (CK), pedagogical content knowledge (PCK), and pedagogical-psychological knowledge (PK) on the diagnosis of subject-specific knowledge or skills, research on the diagnosis of cross-domain skills (i.e., skills relevant for more than one subject), such as scientific reasoning, is lacking although students’ scientific reasoning skills are regarded as important for multiple school subjects (e.g., biology or physics). This study investigates how the accuracy of pre-service teachers’ diagnosis of scientific reasoning is influenced by teachers’ own scientific reasoning skills (one kind of CK), their topic-specific knowledge (i.e., knowledge about a topic that constitutes the thematic background for teaching scientific reasoning; which is another kind of CK), and their knowledge about the diagnosis of scientific reasoning (one kind of PCK) and whether the relationships between professional knowledge and diagnostic accuracy are similar across subjects. The design of the study was correlational. The participants completed several tests for the kinds of professional knowledge mentioned and questionnaires for several control variables. To ensure sufficient variation in pre-service teachers’ PCK, half of the participants additionally read a text about the diagnosis of scientific reasoning. Afterwards, the participants completed one of two parallel video-based simulations (depicting a biology or physics lesson) measuring diagnostic accuracy. The pre-service teachers’ own scientific reasoning skills (CK) were a statistically significant predictor of diagnostic accuracy, whereas topic-specific knowledge (CK) or knowledge about the diagnosis of scientific reasoning (PCK), as manipulated by the text, were not. Additionally, no statistically significant interactions between subject (biology or physics) and the different kinds of professional knowledge were found. These findings emphasize that not all facets of professional knowledge seem to be equally important for the diagnosis of scientific reasoning skills, but more research is needed to clarify the generality of these findings

Basic needs support and achievement emotions in daily research of life scientists considering academic positions

Emotions are a crucial factor in daily research of academic staff and, accordingly, affect scientific progress. Already before but especially during the COVID-19 pandemic, the strong connection between working conditions and work-related emotional states as antecedents for mental health of academic staff gained more and more attention. However, in depths investigations of researchers’ emotions in academia are still rare. In the highly competitive field of academia, experiencing the working environments as supportive may be an important influential factor for researchers’ emotions. On a structural level, academic positions may also be tied to different emotional experiences. Taking a Self-Determination Theory approach, we therefore investigate, whether a basic need-supportive environment (regarding perceived competence and autonomy support, and social relatedness to the scientific community) and the academic position (research assistants without leading responsibility and principle investigators with leading responsibility) predict activity-related achievement emotions (enjoyment, anger, frustration, and boredom) during daily research activities. However, measurements on basic needs support and achievement emotions tailored to the specific academic research context are lacking. Therefore, this study is aimed at developing fitted scales on these constructs. In a cross-sectional survey, we questioned N = 250 life scientists in 13 German universities. Results of multiple linear regression analyses suggest that supportive environments in academia were positively associated to the level of experienced enjoyment and negatively to the level of experienced frustration. Surprisingly, social relatedness to the scientific community does not affect frustration. Principle investigators report a more favorable emotional pattern with higher levels of enjoyment than research assistants. However, the level of experienced frustration was not affected by the academic position. The scales on anger and boredom seemed not to differentiate emotional experiences on these two negative achievement emotions in the research context accurately. Therefore, we needed to exclude anger and boredom from analyzes. Further research on these achievement emotions is needed. We discuss our findings on enjoyment and frustration and derive both theoretical and practical implications, taking an international and interdisciplinary perspective

Effects of Teachers' Professional Knowledge and Their Use of Three-Dimensional Physical Models in Biology Lessons on Students' Achievement

Using three-dimensional physical models elaborately in their learning, students can develop high-level understanding of models and modeling in science, thereby attaining higher achievement. However, there are in the literature few indications of how teachers should use three-dimensional physical models in instruction and whether teachers' professional knowledge is a prerequisite for teaching with elaborate use of models. Therefore, our study used a mixed-methods approach to analyze the effects of biology teachers' domain-specific pedagogical content knowledge (PCK) and content knowledge (CK) on students' achievement mediated by elaborate model use (ELMO). Our quantitative sample comprised 36 German secondary school teachers whose lessons on the topic of neurobiology were videotaped twice (N = 72 lessons). Teachers completed professional knowledge tests on their PCK and CK. Students' achievement was measured using pre- and post-knowledge tests. Our qualitative analysis involved five selected teachers according to aspects of ELMO. The results of our study indicated that teachers' PCK and CK had no direct effect on students' achievement. However, teachers' PCK had a significant indirect and positive effect on students' achievement mediated by ELMO. The findings of our study can provide teachers and researchers examples of how to implement biology instruction with elaborate use of three-dimensional physical models

Unterrichtsqualität in den Naturwissenschaften. Eine vergleichende Gegenüberstellung von Ansätzen zwischen Fachspezifik und Generik

What constitutes to good science teaching and to which extent should criteria of instructional quality be considered subject-specific or generic are fundamental questions within educational research. Currently, a consensus about the necessity to differentiate and add domain-specific criteria to the broadly used basic dimensions of teaching quality, classroom management, constructive support and cognitive activation has emerged in science education. However, there are many approaches to differentiate and add to the three basic dimensions. In the context of this contribution, three approaches of instructional quality were selected and compared in order to arrive at a comprehensive picture from the perspective of the natural sciences. For this purpose, the three science specific approaches were compared with regard to the purpose of use, the theoretical foundation and the operationalization of individual criteria of instructional quality. Subsequently, the criteria used in one approach were transferred into the other two approaches to compare their compatibility. Five categories were identified, which can be used for a future systematic comparison with other approaches. The article thus presents a possibility to systematically relate different research approaches of instructional quality to each other in order to obtain a comprehensive picture of instructional quality.Die Frage danach, was einen guten naturwissenschaftlichen Unterricht ausmacht und die Frage, inwiefern Unterrichtsqualitätsmerkmale fachspezifisch oder generisch betrachtet werden müssen, sind grundlegende Fragestellungen mit denen sich die Unterrichtsqualitätsforschung beschäftigt. Inzwischen zeichnet sich in den Naturwissenschaftsdidaktiken ein breiter Konsens ab, dass die drei Basisdimensionen der Unterrichtsqualität, Klassenführung, konstruktive Unterstützung und kognitive Aktivierung, fachspezifisch ausdifferenziert und ergänzt werden müssen. Zur konkreten fachspezifischen Ausdifferenzierung und Ergänzung existieren in den Naturwissenschaftsdidaktiken jedoch unterschiedliche Ansätze. Im Rahmen dieses Beitrages wurden exemplarisch drei Ansätze zur fachspezifischen Ausdifferenzierung von Unterrichtsqualitätsmerkmalen herausgegriffen und vergleichend betrachtet, um so zu einem umfassenden Bild aus der Perspektive der Naturwissenschaften zu gelangen. Dazu wurden die drei Ansätze aus dem naturwissenschaftlichen Fachbereich hinsichtlich des Verwendungszwecks, der theoretischen Fundierung und der Operationalisierung einzelner Qualitätsmerkmale verglichen. Anschließend wurden die in einem Ansatz genutzten Qualitätsmerkmale jeweils in den beiden anderen Ansätzen verortet. Hierbei konnten fünf Kategorien herausgearbeitet werden, die für einen zukünftigen systematischen Vergleich mit weiteren Ansätzen genutzt werden können. Der Beitrag stellt somit eine Möglichkeit vor, unterschiedliche Forschungsansätze zur Unterrichtsqualität systematisch aufeinander zu beziehen, um so ein umfassendes Bild der Unterrichtsqualität zu erhalten
