The paper's main contribution—that pre-service teachers in resource-limited settings welcome immersive VR—requires that they actually encountered immersive VR, but the method section shows they did not. This is not an external-consensus dispute; it is an internal mismatch between data collection and conclusion. The paper's own text supplies the limitation in §3.2, which makes the concern concrete rather than speculative. Other weaknesses (convenience sample from researchers' home colleges, no baseline measure, short excerpts instead of full raw qualitative data) are real but secondary; even if participants were representative and truthful, the inference from screen-viewing to immersive VR would remain unsupported. The verdict should remain conditional: the paper can be repaired by reframing its claims and adding limitations, but as written it overreaches. I would not reject outright because the qualitative data may still contain useful evidence about perceptions of screen-based VR demonstrations, and the reported challenges (connectivity, equipment access) are likely informative in their own right. No verdict adjustment is needed because the reader's CONDITIONAL rating already captures this concern.","tokens_in":5513,"tokens_out":2920,"duration_ms":29514,"concrete_test":"Obtain the anonymized focus-group transcripts and reflective-journal entries; code each positive or negative statement for whether it references (a) what was seen on the Portal Screen, (b) imagined first-person headset use, or (c) generic expectations about VR.

A complementary check: run a small between-subjects comparison using the same lesson with a headset condition versus a screen-only condition; if the headset group reports higher presence and different perceived benefits, the current abstract overstates what the screen-only data can show.","verdict_should_be":"UNCHANGED","load_bearing_attack":"Section 3.2 states: 'participants were without VR headsets but joined the session via the Portal Screen, allowing them to view the VR environment through a screen projection.' The abstract and Section 4.5 nevertheless conclude that 'VR offers immersive and interactive experiences' and that participants 'believe VR's immersive capabilities could enhance both teacher preparation and learner engagement.' The inferential gap is load-bearing: the study measured responses to a two-dimensional screen-mediated demonstration of a VR platform, not to head-mounted immersive VR. Positive comments such as 'VR is very good and helpful' may reflect the novelty of the projected demonstration or social desirability, not the immersive qualities that the paper foregrounds. Without headset exposure, participants cannot experientially judge immersion, presence, or embodied interaction; their statements about 'immersive capabilities' are predictions, not perceptions. The conclusion that 'initial exposure to VR generated a positive perception' is therefore supported only for 'exposure to a projected VR video.' This is a construct-validity problem, not a mere wording issue, because the policy recommendations (VR as a substitute for Zoom or field trips) depend on the immersive affordances that were never experienced. The limitation appears in the manuscript itself, so the repair is feasible: reframe claims as perceptions about a screen-based VR demonstration and separate experiential claims from speculative ones.","agreement_with_reader":"agree"},"referee_report":{"model":"deepseek-v4-flash","summary":"This manuscript reports a qualitative case study of 36 Ghanaian pre-service teachers from two colleges of education who participated in a VR-facilitated guest lecture.

The authors are honest enough to say in Section 3.2 that participants watched the VR environment through a Portal Screen projection and never wore headsets. That admission does more for the paper's credibility than the abstract does.\n\nWhat the paper does well: it reports infrastructure and connectivity barriers that are consistent with the broader Ghanaian ed-tech literature, and the direct quotes support a modest claim about positive reactions to a screen-based demonstration. The thematic analysis is straightforward, and the recommendations—training, infrastructure, local content—are sensible and not inflated.\n\nThe load-bearing problem is that the abstract and Section 4.5 credit VR's immersive and interactive capabilities, but the participants could not experience immersion. They were watching a two-dimensional projection. Their statements about immersive potential are predictions, not perceptions. The first research question asks how participation influences perceptions, yet there is no baseline measurement, so the direction of influence is assumed. These two issues mean the central conclusions overreach the data. That said, the flaw is repairable: reframe the findings as perceptions of a screen-based VR demonstration, distinguish experiential from speculative claims, and soften the recommendations accordingly.\n\nThe self-citations [14,16,17] point to prior Ghanaian ed-tech work, and recruiting from the authors' home colleges raises minor independence concerns, but I don't see evidence of circular reasoning—the data are primary and not fitted to any model.\n\nWho is this for? Policymakers in similar resource-limited settings and researchers building a local literature on VR adoption. It doesn't resolve a general theoretical question, and the sample is convenience-based, but it is a legitimate local data point. With revision, it could be a useful case study. I would send it to peer review, with the clear expectation of a major revision that fixes the construct-validity framing.

Participants also said VR could reduce the need for expensive field trips, while cautioning that poor internet, lack of equipment, and insufficient training are obstacles to integration.

Participants believed VR could enhance both teacher preparation and learner engagement, and they specifically noted its potential to address costly educational field trips. The same participants identified limited infrastructure, unreliable internet connectivity, and insufficient access to VR equipment as barriers. The paper takes these perceptions as evidence that VR can be a useful supplement in resource-limited teacher education if the infrastructure gaps are addressed.","pith_inferences":["Because no

instruction is the natural next step.","If the screen-projection experience is enough to create positive perceptions, the per-learner cost of initial VR exposure could be far lower than headset-based
