Dua kutub persepsi terkait pembelajaran berbasis konstruktivisme dan pembelajaran berbasis behaviorisme melahirkan variasi pada jenis model pembelajaran dengan argumen kelebihan dan kekurangannya masing-masing yang berpengaruh secara langsung terhadap hasil belajar dan kemampuan berpikir peserta didik. Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir peserta didik berdasarkan klasifikasi dari Hillocks dan Shulman yakni substantive, mechanical-syntactic, formal-rhetorical, dan combine mechanical-formal, metode penelitian melalui studi kualitatif dengan menganalisis jawaban peserta didik yang telah melalui pembelajaran aljabar dasar dengan menggunakan model pembelajaran ekspositori. Hasil analisis diperoleh temuan kemampuan berpikir peserta didik yang ditinjau dari jenis kemampuan berpikir, peserta didik menggunakan kemampuan berpikir substantive dan mechanical-syntactic dalam menyelesaikan masalah/soal yang diberikan oleh pendidik, kemudian permasalahan pengetahuan awal (prior knowledge) muncul dalam tahapan penyelesaian soal peserta didik, ketiadaan (lupa/tidak tahu) pengetahuan awal menjadikan beberapa soal yang diberikan menemui hasil yang keliru meskipun peserta didik menggunakan salah satu dari dua kemampuan berpikir tersebut (substantive, mechanical-syntactic). Implikasi dari masalah tersebut, peserta didik harus diupayakan melakukan peninjauan ulang (looking back) atas uraian jawaban yang telah dia kerjakan, dengan menganalisis jawaban dari pengetahuan lain (pengetahuan awal) yang mungkin ada dalam tahapan jawabannya.

The optimum portion of learning activities of students in a learning becomes urgent given to students, with the ultimate goal of obtaining the expected learning outcomes. However, the reality that occurs, the learning process often marginalizes the activities of students, one of the causes of this problem is the learning process that is fixed on the old pattern, namely the one-way learning process, from the teacher to the students, the teacher carries out learning by ignoring the optimization of participants' learning activities students, learning activities of students are only limited to listening and or taking notes. In other words, the teacher is active while the child is receptive. So that learning outcomes are expected to be at a low level or may not be achieved at all. This research is a Classroom Action Research (CAR/PTK), PTK is defined as a teacher's measured and systematic effort to solve problems that arise in learning events in his class, as well as to determine the quality of the process and learning outcomes of students. Solving these problems is done inclusive in the implementation of learning that is practical, situational, conditional, and contextual. The conclusion of this study is that cooperative model of TPS type can relatively improve student learning activities, cooperative model of TPS type can relatively improve student learning outcomes, and learning by using cooperative model of TPS type obtain positive responses from students.

Since its independence, Indonesia has had to overcome numerous difficulties. Terrorism, radicalism, intolerance, and separatism (TRIS), which endangers Indonesia's unity, are one of the problems. According to numerous studies, many colleges are affected by the threats of terrorism, radicalism, intolerance, and separatism. This study aims to portray how religious moderation is implemented in non-religious universities in West Java. The implementation of religious moderation is seen from six indicators: understanding the concept, university policies about religious moderation, national commitment, tolerance, anti-violence attitudes, the accommodation of local wisdom, and compliance with laws and regulations. A mixed-method approach was used in this study, which was conducted at ten universities in West Java. Observation, interviews, documentation, and questionnaires were used to obtain the data. University leaders, lecturers, and students served as the data sources. The study concludes that non-religious universities in West Java have a good and enough carrying capacity and anticipatory readiness to stop the expansion of TRIS by enforcing religious moderation. However, to have a powerful deterrent against the rise of terrorism, radicalism, intolerance, and separatism, it is vital to deepen and affirm the commitment to religious moderation.

The main problem in this study is students' ability to think mathematically in solving mathematical problems in learning social arithmetic in their class through minimum guidance-based learning (PBL and DL). This research uses a mixed method to look at the description of students' mathematical thinking abilities and the tendency of these abilities based on students' self-efficacy levels. The results showed that the increase in students' mathematical thinking skills at each level of low self-efficacy based on n-gain calculations. In addition, there is no significant difference in the scores for improving students' mathematical thinking skills based on the learning model and the level of self-efficacy. There is no significant interaction between the Learning Model and the Level of Self-efficacy in determining the increase in the average score of students' mathematical thinking abilities. Other findings show that students with low self-efficacy tend to have limitations in the ability to think mathematically in the process of conjecture and convincing. On the other hand, students with moderate and high self-efficacy have more complete mathematical thinking abilities, including specialization, generalization, conjecture, and convincing. However, in the process of conjecture and convincing, two sub-processes are found, namely knowledge modification using factual knowledge, contextual tools, or substantive thinking, as well as the process of selecting relevant information in solving problems. Therefore, the two groups are divided into four groups based on the way students use conjecture and convincing mathematical thinking abilities, namely: (1) students use specialization mathematical thinking skills based on the knowledge learned from the teacher, (2) students use specialization mathematical thinking abilities based on knowledge acquired in everyday life, (3) students use convincing mathematical thinking abilities by examining the formula used or based on knowledge learned from the teacher, and (4) students use convincing mathematical thinking abilities based on the knowledge obtained in everyday life (factual knowledge).
