Diagnostic Competences

Teachers’ diagnostic competences are essential with respect to student achievement, classroom assessment, and instructional quality. Important components of diagnostic competences are teachers’ professional knowledge including content knowledge (CK), pedagogical knowledge (PK), and pedagogical content knowledge (PCK), their diagnostic activities as a specification of situation-specific skills, and diagnostic accuracy. Accuracy is determined by comparing a teacher’s observation of classroom incidents with subject-specific challenges to be identified from scripted instructional situations. To approximate diagnostic situations close to real-life, the assessment of science teachers’ diagnostic competences requires a situated context that was provided through videotaped classroom situations in this study. We investigated the relationship between professional knowledge (PCK, CK, PK) of 186 pre-service biology teachers, their diagnostic activities, and diagnostic accuracy measured with the video-based assessment tool DiKoBi Assess. Results of path analyses utilizing Rasch measures showed that both PCK and PK were statistically significantly related to pre-service teachers’ diagnostic activities. Additionally, biology teachers’ PCK was positively related to diagnostic accuracy. Considering higher effect sizes of PCK compared to PK, the findings support previous findings indicating the importance of PCK, thus demonstrating its importance in the context of subject-specific diagnosis as well.

Psychological 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.

Teachers Perceptions

The integration of Information and Communications Technology (ICT) in classrooms has been a challenge for the educational systems that aim to cope with the needs and the demands of the 21st century. The TPACK framework represents the knowledge needed by teachers bringing together content knowledge, technological knowledge and pedagogical knowledge with the aim of integrating ICTs into teaching-learning processes. The aim of this study is to determine the primary science teachers’ perceptions of technological pedagogical content knowledge (TPACK) addressing teachers’ perceptions of the affordances of technology application in instruction. A total of 133 prımary science teachers in Malaysia were surveyed (Female= 67, Male= 66). Data were collected through “Technological Pedagogical and Content Knowledge” (TPACK) scale. The questionnaire consisted of 47 questions about TPACK and is based on the survey instrument developed by Schmidt et al. (2009). TPACK involving the seven factors of technological knowledge (TK), pedagogical knowledge (PK), content knowledge (CK), technological content knowledge (TCK), technological pedagogical knowledge (TPK), pedagogical content knowledge (PCK), as well as synthesized knowledge of technology, pedagogy, and content (TPC). The findings indicate that primary science teachers perceive higher self-confidence in pedagogical knowledge in general. Further, no differences between science teachers’ perceptions according to thier gender, while there are diferences between the teachers perceptions of PK, CK, and PCK accordıng to their age

Design Paper

In a diagnostic context of reasoning about instructional quality, scientific reasoning skills can be described as diagnostic activities, which require professional knowledge. Different approaches to enhance pre-service teachers’ professional knowledge (PCK, CK, PK), as well as diagnostic activities exist. However, results about their effectiveness are still inconsistent. We systematically investigated the effectiveness of self-directed knowledge acquisition via texts on PCK, CK, PK, and diagnostic activities of 81 pre-service biology teachers following an experimental design. Paper-pencil tests, measuring PCK, CK, and PK, and the video-based assessment tool DiKoBi Assess, measuring diagnostic activities in the context of diagnosing instructional quality, were used pre and post an intervention. Intervention included four treatments on self-directed knowledge acquisition via texts on (1) PCK, (2) CK, (3) PK, (4) combination PCK/CK/PK. Treatment (5) served as control. Mixed ANOVAs showed large time effects for PCK and CK, but no interaction effect concerning knowledge facets between time and treatment for any of the treatments. Time effects might be due to pre-service teachers’ scientific reasoning on biology instruction that activated knowledge. An ANCOVA showed no significant effect of treatment on diagnostic activities either. We conclude that scientific reasoning about instructional quality is more effective for knowledge acquisition than text-work.

The study investigates how Science teachers articulate their self-confidence in teaching Science with technology. Technological Pedagogical Content Knowledge (TPACK) is used as the primary tool to describe their practice. Using a quantitative approach, with an initial survey of 408 science teachers from 59 secondary schools in a state in East Malaysia, descriptive and inferential statistics were conducted to assess science teachers’ level of TPACK and discriminate differences between perceptions on TPACK related to their teaching experience. Findings revealed that the level of Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK) and Pedagogical Content Knowledge (PCK) are high, in comparison to their Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK) and Technological Pedagogical Content Knowledge (TPACK) which were recorded at a moderate level. The study also found how teachers with more extensive experience teaching reported higher confidence with their CK, PK and PCK. Novice teachers indicated slightly higher confidence in their TK. The study provides a set of determiners for professional development opportunities for Sarawak Science teachers to upskill their knowledge to integrate science content, pedagogy, and technology.
