The positive effect of peer assessment and self-assessment strategies on learners' performance has been widely confirmed in experimental or quasi-experimental studies. However, whether peer and self-assessment within everyday mathematics teaching affect student learning and achievement, has rarely been studied. This study aimed to determine with what quality peer and self-assessment occur in everyday mathematics instruction and whether and which students benefit from it in terms of achievement and the learning process. Two lessons on division were video-recorded and rated to determine the quality of peer and self-assessment. Six hundred thirty-four students of fourth-grade primary school classes in German-speaking Switzerland participated in the study and completed a performance test on division. Multilevel analyses showed no general effect of the quality of peer or self-assessment on performance. However, high-quality self-assessment was beneficial for lower-performing students, who used a larger repertoire of calculation strategies, which helped them perform better. In conclusion, peer and self-assessment in real-life settings only have a small effect on the student performance in this Swiss study.

This study focuses on online supervisory written feedback on PhD supervisees’ performance, given explicitly through online communication, particularly during the first wave of COVID-19. This unusual situation has brought many different effects on students’ academic lives. This scenario has influenced both students’ and teachers’ mutual communication. A directed qualitative content analysis (DQCA) approach was adapted from previous research and modified for the present context. The current study planned to bring forth the supervisee and supervisors’ perception of the communication and feedback process, considering that online feedback and communication has been a new experience for most students. According to the findings, teachers/supervisors give feedback on students’ production, whereas teacher-student communication also seemed crucial for the performance improvising of learners. The result brought forth a wide range of social, educational, and surprisingly psychological issues both supervisees and supervisors faced during online communication during COVID-19.

Learning activities are conducted to help students achieve optimal academic achievement. This research aims to optimize student academic achievement through a learning process that integrates comprehensive formative assessments, including formative tests, self-assessment, peer assessment, and the initiator of creating summaries or concept maps that are given to students in a structured manner at the end of every lesson. The research method used was a quasi-experimental method with a 2x2 factorial design. Students enrolled in the biology education program of the basic physics course for the 1st semester of the 2019 academic year participated in this study. The participants were 66 undergraduate students divided into two classes. Thirty-four students in the experimental group were in class A, while 32 students in the control group were in class B. Data were collected using a learning outcome test instrument to measure academic achievement, which was tested at the end of the semester. Data were analyzed using a two-way ANOVA. This study concluded that a learning process that includes comprehensive formative assessment significantly affects students' academic achievement. These findings support the theory that formative assessment provides feedback, correction, and improvement in student learning.

This study examines teachers’ perceptions of assessment and their relationship with instructional practice in primary education. It examines whether teachers perceive assessment as a tool to support student learning and development or as a mechanism for ensuring educational quality through teaching evaluation and exam preparation. The research is based on a survey conducted with 396 primary school teachers in Croatia, including both lower and upper grades. Descriptive statistics, Pearson’s correlation coefficients, multiple regression analysis, and one-way ANOVA were employed to analyze the data. The findings indicate a statistically significant correlation between teachers’ perceptions of assessment and the assessment strategies they implement in the classroom. Formative assessment is widely supported, yet summative methods remain prevalent. Lower primary teachers apply formative strategy more frequently than their upper primary counterparts. Teachers with mentor status demonstrate a stronger inclination toward student-centered assessment practices and report applying them more consistently. The results highlight the prevalence of a hybrid assessment model in which teachers balance formative and summative approaches, seeking to meet institutional requirements while simultaneously supporting student development. The findings underscore the need for continuous professional development and systemic support to empower teachers in adopting assessment practices that effectively enhance student learning and elevate educational quality. Training programs should be designed to address the specific needs of primary teachers, recognizing differences between lower and upper levels, as well as subject-specific requirements in grades 5 through 8. A targeted approach would facilitate the effective integration of contemporary assessment strategies into everyday teaching, supporting student progress and educational improvement.
