This study explored the practice and spacing-of-practice effects in people living with dementia during an artistic painting activity. The video recordings of 23 participants were systematically observed during their first and fourth session of the activity. Improvements in independence, engagement, and well/ill-being expressions were analyzed from the first to the fourth session. Moreover, it was analyzed whether a group who had practiced three times a week (n = 12) improved more than a group who had practiced once a week (n = 13). Participants became more independent as they practiced, but the spacing of the sessions did not show any significant effect. Participants with severe dementia showed greater independence improvements than participants with mild to moderate dementia, although they required significantly more assistance throughout the entire study. The positive rates in active engagement and well/ill-being expressions suggest that artistic painting activities promote the motivation and well-being of participants, including those in the severe stage of dementia.

The Metacognitive Awareness Inventory (MAI) is used all over the world to identify metacognitive components that are relevant to learning. However, there is not enough evidence confirming its factorial structure or the suitability of its Shortened Version, proposed by various authors. Also, to date, the MAI has not been validated in the Spanish context.After adapting the MAI to Spanish, it was administered to 1076 university students from different regions of Spain. Different structures of the MAI Shortened Version, with 19 items, were compared with the structures of the original 52-item MAI. Indexes of validity and reliability were analyzed, considering the factorial structure and relationships to other validated questionnaires.Only the MAI Shortened Version that differentiates between knowledge and regulation of cognition achieved a good fit. These two scales showed good convergent and divergent validity, high criterion validity in relation to academic achievement, high test- retest reliability, and high internal reliability.results support the traditional differentiation between knowledge of cognition and regulation of cognition, but only for the Shortened Version of the MAI. This instrument allows quick evaluations and identification of these components in Spanish contexts with adequate metric properties.

Nowadays, how to encourage students' reflective thinking is one of the main concerns for teachers at various educational levels. Many students have difficulties when facing tasks that involve high levels of reflection, such as on STEM (Science, Technology, Engineering and Mathematics) courses. Many also have deep-rooted anxiety and demotivation towards such courses. In order to overcome these cognitive and affective challenges, researchers have suggested the use of "Problem-Solving before Instruction" (PS-I) approaches. PS-I consists of giving students the opportunity to generate individual solutions to problems that are later solved in class. These solutions are compared with the canonical solution in the following phase of instruction, together with the presentation of the lesson content. It has been suggested that with this approach students can increase their conceptual understanding, transfer their learning to different tasks and contexts, become more aware of the gaps in their knowledge, and generate a personal construct of previous knowledge that can help maintain their motivation. Despite the advantages, this approach has been criticized, as students might spend a lot of time on aimless trial and error during the initial phase of solution generation or they may even feel frustrated in this process, which might be detrimental to future learning. More importantly, there is little research about how pre-existing student characteristics can help them to benefit (or not) from this approach. The aim of the current study is to present the design and implementation of the PS-I approach applied to statistics learning in undergraduate students, as well as a methodological approach used to evaluate its efficacy considering students' pre-existing differences.

Invention activities can promote reflective learning processes. However, their inclusion in educational practice can generate doubts because they take up time that can otherwise be invested in explaining content, and because some students might experience frustration and anxiety while trying to solve them. This study experimentally evaluated the efficacy of invention activities in a university statistics class, considering both emotions (self-reported) and learning achieved. In total, 43 students were randomly assigned to either (a) inventing variability measures before receiving instruction about the topic of statistical variability, or (b) completing a similar problem-solving activity, but only after they had received guidance with a worked example concerning the target concepts. Students in the first condition acquired greater conceptual knowledge, which is an indicator of deep learning. The emotions experienced during the learning activities were similar in both learning conditions. However, it was notable that enjoyment during the invention phase of the invention condition was strongly associated with higher achievement. Invention activities are a promising educational strategy that require students to play an active role, and can promote deep learning. This study also provides implementation guidelines for teachers while discussing the possibilities offered by new technologies.
