This research aims to know validity of thermochemistry suplement book based problem solving to train students metacognitive skills includes the content and construct. Content validity includes the suitability of the material and questions. Construct validity includes presentation and readability techniques. Problem solving model has 4 steps, that are understanding the problem, devising a plan, carrying out the plan, and lock back. Metacognitive skills consist of 3 components, namely planning, monitoring, and evaluating. The type of research used is the Research and Development (R&D) from Sugiyono. The supplement book was assessed by 3 experts in the field of chemical education using a validation instrument. The results showed that a chemical supplement book based on problem solving to train students' metacognitive skills on thermochemical material was very good with a score of 91.6% in content validation and 84.9% in construct validation.

Objective Improve the content validity of the instrument for classification of pediatric patients and evaluate its construct validity. Method A descriptive exploratory study in the measurement of the content validity index, and correlational design for construct validation through exploratory factor analysis. Results The content validity index for indicators was 0.99 and it was 0.97 for graded situations. Three domains were extracted in the construct validation, namely: patient, family and therapeutic procedures, with 74.97% of explained variance. The instrument showed evidences of content and construct validity. Conclusion The validation of the instrument occurred under the approach of family-centered care, and allowed incorporating some essential needs of childhood such as playing, interaction and affection in the content of the instrument.

Purpose - This study investigated the content and construct validity of the Reflective-Metacognitive Learning (RML) Model, and the effectiveness of the RML Model in comparison with Cognitive-Metacognitive Learning (CML) Model in improving students’ metacognitive knowledge, skills, and awareness after the learning process. Methodology - This experimental study began with developing the RML Model, which covered planning, development and evaluation. A focus group discussion involving four experts in science education was conducted to determine the validity of the RML Model and its supporting devices in terms of content validity and construct validity. An experimental study using a randomized pretest-posttest control group design was then implemented on forty senior high school students to evaluate the effectiveness of the RML Model against the CML Model. Data were analyzed descriptively and statistically. Findings - The results showed that the RML Model was highly valid in terms of content validity and construct validity, Metacognitive knowledge increased to a high degree, while metacognitive skills and awareness increased to a medium degree. Based on the results, it was concluded that the RML Model was valid and more effective than the CML Model in terms of improving students’ metacognitive ability. Significance - The RML Model, which is marked by the reflection of thinking processes as the core, is expected to improve students' metacognitive ability.
