Background: Guidance during inquiry learning plays an important role in developing conceptual understanding and inquiry skills. This study analysed learner‐tutor interactions in a simulation‐assisted learning environment to investigate how tutor guidance enabled knowledge construction and fostered epistemic practice. Objectives: This research aimed to illuminate challenges learners encounter in the inquiry process and forms of guidance that support learning in both conceptual and epistemic aspects. Methods: This study uses a mixed methods approach. We analysed video recordings in which nine participants asked 72 questions and the microsequences of interactions immediately surrounding and including each question. We coded properties of each question and whether the tutors' utterances were intended to increase (upregulate) or decrease (downregulate) the complexity of the inquiry processes, and used a two‐step cluster analysis to explore groupings emerged from tutors' regulation guidance and learners' questions. Results and Conclusions: The regulatory intent of tutors' utterances depended on various characteristics of student questions. The microsequences clustered in five categories: 1) upregulated investigation and inference, 2) upregulated evidence‐based justification, 3) downregulated cognitive load, 4) downregulated procedural uncertainties, and 5) downregulated perceptual dissonance. Our findings suggest tutors offering guiding prompts should consider dual processes in the inquiry and, by strategically prompting them, strike a balance between the goals of guiding learners to discover scientific knowledge and grounding their conceptual understanding in concepts, data, and procedures. Implications: We emphasize conceptual and epistemic learning should be concurrently guided in scientific inquiry. We propose a bidirectional guidance model as a pedagogical approach to guide instructional practice. Lay Description: What is currently known about the subject matter: Rapid technological change urges schools to equip students with research and inquiry skills.Computer simulations provide an information‐rich environment for inquiry‐based learning.Guidance in inquiry learning is important for knowledge acquisition and the development of inquiry skills. What this paper adds: We illuminated challenges learners encounter in the inquiry learning process.We analysed forms of guidance that support learning in both conceptual and epistemic aspects.We identified dual processes involved in the inquiry process that have important implications.We proposed a bidirectional model for adaptive guidance in scientific inquiry. Implications of study findings for practitioners: Adaptive guidance facilitates conceptual and epistemic understanding by stimulating curiosity and reducing uncertainty in the inquiry process.Conceptual and epistemic learning need to be concurrently guided in scientific inquiry.

Blended synchronous learning (BSL) represents several contexts that enable to bring remote students into the classroom, in real time, by the means of videoconferencing, web conferencing and virtual world. As BSL seems to be more and more implemented in many higher education institutions, especially in the current context of the COVID‐19 pandemic, and given the recent interest and scarce published research in BSL, more studies are needed on this kind of learning. The purpose of this research was to explore students and instructors perspective regarding their experience in BSL, according to three dimensions: pedagogy, technology and organization/logistics. To meet the study objective, a qualitative methodology was adopted. The study participants were remote students (n = 4) and face‐to‐face students (n = 4) enrolled in a graduate program in education offering only blended synchronous courses, and instructors (n = 5) in this program. Semi‐structured interviews were selected as the data collection method. Nine sub‐themes in reference to the three dimensions emerged from the study participants. They have also highlighted some challenges associated with BSL. The results reported in this study should provide faculties and higher education administrators with additional information and guidance, based on empirical data, on the use of BSL if they wish to implement it in academic programs. Moreover, in regard to the challenges revealed by the study participants, the results will permit to surpass the obstacles when implementing BSL successfully. Lay Description: What is already known about this topic: Blended synchronous Learning (BSL) is more and more used in higher education.BSL may be a good alternative for higher education institutions in the context of the COVID‐19 pandemic, as it permits to reduce the number of involved students in face‐to‐face activities, by offloading some students to online from their home or a remote site.Despite its gain in popularity, little research has been performed on BSL and this research is somewhat sparse.Further research and recommendations are needed for faculties and higher education administrators to assist them in ascertaining what works and what does not in BSL. What this paper adds: The purpose of this study was to report on students and instructors experience on BSL, with remote students participating from multiple sites and face‐to‐face students from a single site.Students and instructors perspectives were explored using three dimensions: pedagogy, technology and organisation/logistics.Challenges associated with BSL were highlighted by the study participants Implications for practice and/or policy: The results of this study will guide faculties in designing and implementing BSL for their students.The challenges highlighted in the study results should be taken into account when implementing BSL.
