Teachers’ Pedagogical Competence in Dealing with Teaching Aids in Tanzania: A Case of a Few Finalist Pre-service Science-teachers

The value of teaching aids in the process of teaching sciences cannot be overstated. The capacity of finalist university pre-service science teachers to incorporate teaching aids into their science classrooms to open up the potential of bringing about the critical features of an intended object into realisation is evaluated in this study. Observations and document reviews were used as data collecting techniques in this descriptive study, and they were used to investigate only 25 student-teachers during their final teaching practice placement. Evidence suggested that the study participants’ ability to select or design teaching aids was low as most of the materials they employed had didactic, structural, and technical concerns. Importantly, the study participants demonstrated significant difficulties in unpacking instructional materials during the science lessons. The study recommended various measures for policy and practice regarding both science teacher-education and science teaching process.

The Future of Science Teacher Education in Tonga

<p>The purpose of this research was to explore and document existing policy and practices contributing to the debate of science teacher education in the Pacific. The study took on a pragmatic approach for a mixed research, drawing from the positives of both the qualitative and the quantitative approaches using the kakala/kakala research frameworks guiding the methodological framework. Being a mixed research, the data collection method involved three elements: one-on-one semi-structured interviews with senior Tongan education officials, document analysis and a teacher questionnaire targeting science teachers. All the interviews were conducted in English and recorded using a digital recording device and transcribed by myself as the researcher. All the science teachers who participated in the questionnaire returned a signed consent form to confirm willingness to participate maintaining anonymity. In order to answer the research question, the study examined the significance of the fibre (fau)used in the kakala weaving process, extracting from the Kakala/Kakala research frameworks the metaphoric conceptual relevance of the fibre (fau) which holds the kakala providing it structural support. Hence the conceptualisation that, the three strands of fibre that holds and maintains the education system in Tonga can be attributed to; (i) strong cultural values, (ii) a clear and definitive education policy framework (Catherwood & Levine, 2004), and high teacher self-efficacy. The self-efficacy of Tongan science teachers is measured for the first time and reported in this study as high to very high on a Likert-type psychometric scale adapted from (Skaalvik & Skaalvik, 2009) to fit the Tongan context. The study also discusses challenges and teacher perceptions of being a science teacher in Tonga and the implications these challenges might pose in future.</p>

Breaching Learners’ Social Distancing through Social Media during the COVID-19 Pandemic

Higher education has been shifted toward blended learning during the COVID-19 pandemic. An increase in social media usage intensity and reduced face-to-face interaction due to the COVID-19 pandemic urged instructional communication researchers to revisit the dynamics of learners’ group development in terms of their socialization and academic performance during the COVID-19 crisis. This research aimed to determine the mediating role of social media sociability between face-to-face socialization and academic performance of higher education students in blended learning environments during the COVID-19 pandemic. It was also the aim of the study to determine the moderating effect of social media usage intensity on social media sociability. A cross-sectional survey was conducted with the students (n = 340) enrolled in science teacher education departments of universities in Pakistan. Partial least squares structural equation modeling (PLS-SEM) was used for multivariate analysis. Results revealed that face-to-face socialization gave an essential start to develop a learning group. However, when face-to-face socialization was reduced due to the COVID-19 pandemic, it was mediated by social media usage in blended learning environments to increase their socialization and academic performance during the crisis. The findings of the study are useful for higher education institutions to adopt social media strategies for students’ socialization during the crisis.

Professional Knowledge and Organizational Commitment of Faculty Members Handling Science Subjects in the University of Eastern Philippines

This study aimed to determine the professional knowledge of faculty members in terms of knowledge of science content, knowledge of general pedagogy, pedagogical content knowledge, and knowledge of the curriculum structure and materials and find out the degree of organizational commitment along with affective, continuance, and normative organizational commitment. A complete enumeration of faculty members handling science teacher education courses in the College of Education and College of Science. Descriptive-observational and survey were employed. The questionnaires were adapted from the framework for Philippine Science Teacher Education published by the Department of Science and Technology (DOST) and University of the Philippines-National Institute for Science and Mathematics Education Development (UP-NISMED) and the organizational commitment along with affective, continuance, and normative commitment constructed and tested. It was found out that faculty members have very high professional; specifically, very high knowledge content, very high knowledge of general pedagogy, and very high knowledge of the curriculum structure and materials. It was also found out that faculty members are very highly committed to the University. Specifically, faculty members are very highly committed to affective, continuance, and normative organizational commitment.

Using Kahoot! As A Formative Assessment Tool in Science Teacher Education

The development of 21st century competencies and skills in science teaching and learning is a key strategic imperative. Game-based learning platforms can be used to promote pedagogic innovation in various educational settings. Game-based applications such as Kahoot! have been increasingly used in education to facilitate meaningful enactment of formative assessment practices. Within the realm of science education, formative assessment is largely perceived as an assessment practice with pedagogic potential to enhance students’ academic performance, motivation and engagement during the teaching and learning process. Kahoot! is an interactive game-based learning platform which can essentially be utilised to enhance students’ academic performance, motivation and engagement in the classroom. This paper explores the role of Kahoot! as a formative assessment tool to enhance students’ academic performance, motivation and engagement with a view to help students to achieve stipulated learning outcomes during remote teaching and learning in undergraduate Physical Sciences teacher education. The research study adopted a generic qualitative design and involved 21 purposively selected preservice Physical Sciences teachers at a South African university. Data was collected through semi-structured interviews and the administration of qualitative user-generated online quizzes with the participants. The findings demonstrated that Kahoot! plays a significant role in enhancing students’ academic performance, motivation and active engagement during remote teaching and learning. Theoretical implications for technology-enhanced teaching and learning are discussed.

Measuring and Fostering Preservice Chemistry Teachers’ Scientific Reasoning Competency

Developing scientific reasoning (SR) is a central goal of science-teacher education worldwide. On a fine-grained level, SR competency can be subdivided into at least six skills: formulating research questions, generating hypotheses, planning experiments, observing and measuring, preparing data for analysis, and drawing conclusions. In a study focusing on preservice chemistry teachers, an organic chemistry lab course was redesigned using problem-solving experiments and SR video lessons to foster SR skills. To evaluate the intervention, a self-assessment questionnaire was developed, and a performance-based instrument involving an experimental problem-solving task was adapted to the target group of undergraduates. The treatment was evaluated in a pre-post design with control group (cook-book experiments, no SR video lessons) and alternative treatment group (problem-solving experiments, unrelated video lessons). Interrater reliability was excellent (ρ from 0.915 to 1.000; ICC (A1)). Data analysis shows that the adapted instrument is suitable for university students. First insights from the pilot study indicate that the cook-book lab (control group) only fosters students’ skill in observing and measuring, while both treatment groups show an increase in generating hypotheses and planning experiments. No pretest-posttest differences were found in self-assessed SR skills in the treatment groups. Instruments and data are presented and discussed.
