Professional Development Workshop for Physical Education Teachers in Southwest China: Benefiting Tai Chi Students with Pedagogical Content Knowledge

Researchers have examined the common and specialized content knowledge (CCK/SCK) of physical education (PE) teachers and compared their pedagogical content knowledge (PCK) with student learning outcomes globally. However, little research has been reported in China on the relationship between PCK and student learning in PE settings. The aims of the study were (i) to investigate the influence of teacher content knowledge (CCK/SCK) on student development stages in PE settings and (ii) to examine the impact of teachers' PCK on students' performance in Tai Chi techniques (TCTs) after six days of instruction. Two PE teachers were chosen from two urban, public, mid-sized middle schools located in Chengdu, Sichuan Province, China. This study involved 332 students from six 5th and six 6th grade classes. The study consisted of 185 5th-grade students (98 boys and 87 girls) and 147 6th-grade students (70 boys and 77 girls). We examined how teacher PCK and student TCT changed after a professional development workshop (PDW). Each PE teacher had two classes randomly assigned to the control or experimental condition groups. This study had three phases. Initially, the control condition was introduced; then, a PDW was provided for the teachers; and finally, the experimental condition was implemented. Teaching behaviors were described using mean values, and t-tests based on the highest TCT scores were conducted to examine the effect of teachers' PCK on students' TCT learning. Furthermore, PCK effect sizes were calculated using Cohen's d. Significant relationships existed between teachers' PCK, CK, and students' knowledge, with effect sizes ranging from 1.92 to 6.82. Additionally, improvements in teachers' PCK were associated with improved TCT performance in students (p < 0.05). Increased knowledge and skills can improve teachers' PCK behavior, resulting in improved student performance in TCTs. These findings may provide evidence for future recommendations regarding knowledge and skill training programs for physical education teachers.
