Teacher emotions are essential for teaching effectiveness and teachers’ professional development. Studying teacher emotions during a program in today’s world is crucial, where teachers are commonly involved in professional development programs. From an ecological perspective, this study employed a case study method to examine the emotions of two Chinese high school mathematics teachers in a 4-year teaching improvement program. Semi-structured interviews, teacher emotion logs, researcher memos, and informal dialogues were all used to collect data. This study aimed to better understand the emotions that Chinese high school mathematics teachers developed and the processes that generated them in their interactions with various ecosystems within a specific professional development program overlay. The study’s findings revealed that the two teachers triggered 65 emotions in their interactions with the various ecosystems over 4 years—A describing 51 and B describing 46—with an overall predominance of positive emotions. They triggered the broadest range of emotions in the mesosystem, particularly during interactions with program companions. During the early, medium, and late stages, their internal psychological factors and interactions with each system changed, resulting in significant changes in their emotions. They all went through phases of mixed sadness and happiness, ending in a state of delight and calmness. Finally, we recommended teachers’ professional development based on the study’s findings.
As one of the most important examinations in China, the National College Entrance Examination (commonly known as the Gaokao, hereafter denoted Gaokao) has a long history and has attracted attention from the Chinese educational community, among others. This study focused on mathematics test items of the Gaokao from the perspective of mathematical culture and examined the national papers (drafted by the Ministry of Education of the People’s Republic of China) of tests from 1978 to 2021 in order to investigate the content and time variation characteristics of mathematics test items reflecting mathematical culture since its restoration. A mathematical culture categorization conceptual framework was established based on previous studies and was applied to test item analysis. Mathematical culture in test items was classified using four categories: Historical Topics, Interdisciplinary Connections, Social Roles, and Aesthetics & Recreation. These were used for data coding and analysis. The results showed that mathematical culture in the mathematics test items of the Gaokao over a 44-year period, in terms of content categories, was diverse but uneven in distribution, with greater focus on demonstrating the social roles of mathematics and less on the historical development of mathematical knowledge. Moreover, the average number of items with mathematical culture during this period was small and fluctuated over time. The content of topics related to social context and technology also changed over time with the distinct characteristics of the times and changes in society. This study provides empirical evidence on how mathematical culture is integrated into test items and how they have changed over time.
