Practicing innovative, constant, dynamic, ongoing and process-oriented assessment techniques with constructive and communicative feedback can consolidate and stabilize learners’ instruction and learning. This study investigated the impact of the think-pair-share (TPS) formative assessment (FA) strategy on Iranian EFL learners' reading comprehension skill and vocabulary knowledge. Sixty male intermediate EFL participants from two intact classes took part in the revised Cambridge Preliminary English Test and forty-eight students were chosen by analyzing their scores considering two standard deviations above or below the mean. The participants were from Allameh Jafari high school of Marand. They were assigned to two intact groups of twenty-four learners. This quasi-experimental study was implemented by using a pretest and posttest design to quantitatively collect data so as to compare the experimental group (EG) and the control group (CG). The EG was assessed through the TPS assessment technique, while the CG was assessed using the product-oriented summative assessment (SA) tool. To find out the effect of the assessment techniques on reading comprehension and vocabulary knowledge, the two groups of the study were assessed for twenty weeks. Then, Independent Samples T-test and the one-way ANCOVA were used to compare and analyze the pretest and the posttest scores of the participants in the two groups. The findings indicated that the EG with the TPS FA technique outperformed the CG with the SA strategy in reading comprehension and vocabulary learning. The findings can be pedagogically rewarding for learners, teachers and theoreticians and may cast light on SLA research in applying FA techniques.

Corporate Social Responsibility (CSR) has become increasingly significant for managerial authorities striving for organizational success. Comprehensive CSR initiatives are essential to address the growing pressures for heightened CSR commitment in corporate entities. These innovations enhance organizational performance within communities and have positive implications for individuals, communities, and state sectors. This study aims to highlight the impact of CSR on product innovation, exploring the mediating role of employer branding within medium and large manufacturing companies of Southern Iran's Bushehr City.

The study serves an applied purpose and employs a descriptive survey method for data collection. Its focus is on 100 medium and large manufacturing enterprises in Bushehr, Iran. Employing a combination of stratified and convenience sampling techniques, a total of 80 companies were chosen for inclusion in the study. To ensure the reliability of the questionnaire, Cronbach's alpha coefficient was calculated at 94%, and content validity analysis was employed for construct validity. The SmartPLS software was utilized to assess research hypotheses. The research instrument used in this study is a two-part survey. The initial section gathers general and demographic data from the participants, while the latter part includes inquiries for research assessment, utilizing a five-point Likert scale, comprising 46 questions in total. During the study, each company received between 3 to 5 in-person surveys. After the data were collected, an average was computed from each company's responses, and one survey per company was chosen as the foundation for the analysis. Consequently, our evaluation was fundamentally rooted in 80 completed surveys.

The achievements indicated that CSR notably and positively influences both product innovation and employer branding. Yet, the impact of employer branding on product innovation didn't show a significant statistical effect. Moreover, the intervening function of employer branding in the connection between CSR and product innovation didn't demonstrate any statistically meaningful importance.

The outcomes of structural equation modeling highlighted the significant and beneficial effect of CSR on product innovation and employer branding in medium to large businesses. Although there wasn't a direct correlation found between employer branding and product innovation, the general results underscored the crucial function of CSR in promoting innovation and brand growth. Companies ought to prioritize social responsibility in their operations, as it is crucial for their survival. It was observed that large corporations are significantly investing in socially responsible actions, proving it's not a burden but rather a competitive advantage. Companies, therefore, need to pour resources into social responsibility initiatives and innovations with the aspiration to meet diverse expectations. Put differently, firms focusing on socially responsible actions tend to innovate more in products and procedures for various reasons, primarily because the orthodox approach is no longer effective. They need to lean on innovation to carry out these practices. Moreover, stakeholders wish to amplify their social involvement which, in turn, bolsters potential innovative responsibility within the companies. Also, activities related to social responsibility compel companies to innovate to meet the requirements of emerging consumers.

Iranian high school students confront various challenges in understanding reading passages and learning vocabulary since appropriate process-oriented assessment techniques with constructive and communicative feedback are not practiced to consolidate instruction and learning. The effect of formative assessment (FA) retelling strategy on vocabulary knowledge and understanding passages was investigated and scrutinized in this quasi-experimental study in the EFL context. Thus, a sample of 48 intermediate EFL students was selected and assigned to two intact groups. The retelling assessment was implemented for the experimental group (EG), while the product-oriented summative assessment was applied to the control group (CG). The pre-test scores were taken at the first phase of the study followed by the eight-week assessment process. Finally, the post-test scores were taken. For the purpose of the analysis, the Independent Samples T-test and the one-way  ANCOVA were utilized to compare and contrast the mean scores. The findings were in favor of the retelling technique which developed the vocabulary command and text comprehension in the EG. Moreover, little or no significant impact was revealed for the product-oriented assessment in the CG. The findings can be pedagogically rewarding for learners, teachers and theoreticians and may cast light on SLA research in applying FA techniques.
